WARNING  
!
The instrument must only be installed and commissioned by qualified  
personnel.  
The device may be used solely for the purposes described in this  
manual.  
The instrument is designed for connection to functional and safety  
extra low voltage.  
Electrical safety depends only on the power supply equipment.  
Pneumatic actuators exert considerable positioning forces. The safety  
precautions of the actuator used must therefore be scrupulously  
observed during installation and commissioning in order to prevent  
injuries.  
We explicitly draw your attention to the necessity of observing safety  
regulations regarding operation in zones subject to explosion hazard,  
if applicable.  
The specifications of the examination certificate valid in your country  
must be observed. Laws and regulations valid in your country must be  
observed for the electrical installation in explosions hazardous areas.  
In Germany these are for example:  
--  
--  
Working reliability regulations  
Regulations for installing electrical equipment in hazardous areas,  
DIN EN 60079-14 (in the past VDE 0165, T1).  
It should be checked whether the available power supply, insofar as  
this is required, is compliant with the power supply specified on the  
rating plate and specified in the examination certificate valid in your  
country.  
Take care to avoid electrostatic discharges within the hazardous area,  
such as can arise if a dry cloth is used to clean the positioner in the  
plastic housing.  
Devices with the protection type “flameproof enclosure” may only be  
opened when the power is off.  
WARNING  
!
Devices with the protection type “intrinsically safe” lose their certifica-  
tion as soon as they are operated with circuits that do not conform to  
the specifications laid down in the examination certificate valid in your  
country.  
The successful and safe operation of this equipment is dependent  
upon its proper handling, installation, operation and maintenance.

Design and Method of Operation  
2
The following chapter describes the mechanical and electrical design,  
the instrument components and method of operation of the positioner.  
2.1 Overview  
The electropneumatic positioner forms a control system in connection  
with an actuator. The current position of the actuator is detected by a  
servo potentiometer and fed back as actual value x. The setpoint and  
actual value are output simultaneously on the display.  
Introduction  
The setpoint w is formed by a current fed to the positioner which at  
the same time serves to supply the positioner in two-wire operation.  
In 3/4-wire operation the supply comes from a 24 V voltage input.  
The positioner operates as a predictive five-point switch by the output  
variable ±∆y of which the integrated actuating valves are controlled with  
pulse length modulation.  
These actuating signals cause fluctuations in pressure in the actuator  
chamber(s) and thus adjustment of the actuator until the control error is  
zero.  
Operation (manual) and configuration (structuring, initialization and  
parameterization) is effected by three keys and a display with the hous-  
ing cover removed.  
The standard controller has one digital input (DI1). This can be config-  
ured individually and can be used for blocking the operating modes for  
example.  
With the Iy-option module, the current actuator position can be output  
as a two wire signal Iy = 4 to 20 mA.  
In addition the actuator can be monitored for two programmable limit  
values which respond on exceeding or dropping below the stroke or  
angle of rotation.  
The limit value alarms are output by the alarm option module which can  
monitor and report the function of the positioner and the actuator addi-  
tionally through a fault message output. The value of the control differ-  
ence dependent on the travel time is monitored in automatic mode. The  
fault signal is always set when the control error cannot be leveled after  
a certain time because for example the valve is blocked or the mains  
pressure is insufficient. The three digital outputs are implemented as  
semiconductor outputs and are error self-reporting, i.e. the outputs re-  
SIPART PS2 Manual  
A5E00074631--06

Design and Functional Principle  
spond even when the power supply fails or the electronics are defec-  
tive.  
The actuator can also be blocked or driven to its final positions depend-  
ing on the configuration for example by an external event via a digital  
input (DI2) on the alarm module.  
If you require electrically independent limit value messages from the  
standard controller, you will have to use the SIA module with the slot  
initiators instead of the alarm module.  
Communication with the controller is possible via the optional HART  
interface.  
To be able to use the positioner with a variety of different part-turn and  
linear actuators, it has a friction clutch and switchable gearing.  
The switchable gearing allows you to adjust the positioner for small and  
large lifts. You can switch using the yellow switch (8, Fig. 2-11, page 28)  
between 33_ (as delivered) and 90_.  
The friction clutch (8, Fig. 2-11, page 28) allows you to set the working  
range, particularly for linear actuators, after installation. You thus do not  
have to ensure symmetrical mounting during the installation.  
As it is not allowed to open the housing of an explosion-proof version in  
a potentially explosive atmosphere, the shaft has an externally fitted,  
additional friction clutch (8, Fig. 2-12, page 31).  
NOTICE  
for the explosion-proof version:  
Only adjust the outer friction clutch (8, Fig. 2-12, page 31). The internal  
friction clutch (8, Fig. 2-11 page 28) is fixed and, for the explosion-  
proof version, must not be adjusted.

2.3.1 Motherboard  
The motherboard contains all the electronic elements such as the CPU,  
memory, A/D converter. It also contains the display and the operating  
keys.  
In addition, the terminal strips for connecting the options modules are  
also on the motherboard.  
2.3.2 Electrical Connections  
The terminals of the standard controller, the Iy- and alarm-option mod-  
ule are arranged at the left-hand front edges and offset against each  
other in staircase form.  
A module cover protects the modules from being pulled out and pre-  
vents incorrect installation.

2.3.4 Mounting Kit  
The positioner can be mounted on almost all actuators with the ap-  
propriate mounting kit.  
2.3.5 Purge air switching (not in the explosion proof version)  
The purge air switch is accessible above the pneumatic terminal strip  
with the housing open (figure 2-7). In the IN position the inside of the  
housing is purged with very small amounts of clean, dry instrument air.  
In the OUT position the purge air is fed directly to the outside air.

2.3.6 Restrictors  
In order to achieve travel times of > 1.5 s in small actuators, the air rate  
can be reduced with the restrictors Y1 and Y2 (figure 2-8, in explosion  
proof version, see figure 2-5, page 19). By turning to the right the air  
rate is reduced up to shutting off. To set the restrictors it is advisable to  
close them and then open them slowly (see initialization RUN3).  
In the case of double-acting valves make sure that both chokes are set  
approximately equal.

Design and Functional Principle  
2.4 Method of Operation  
The electropneumatic positioner SIPART PS2 forms a control circuit  
with the pneumatic actuator in which the actual value x is the position  
of the actuator bar in linear actuators or the position of the actuator  
shaft in part-turn actuators and the command variable w is the  
actuating current of a controller or a manual control station of 4 to  
20 mA.  
The stroke or part-turn movement of the actuator is transferred by the  
appropriate mounting accessories, the feedback shaft and a play-free  
switchable gearwheel to a high quality conductive plastic potentiometer  
and to the analog input of the microcontroller. The current position can  
also be preset for the positioner via an external sensor. The detection  
of the stroke or rotation andle is performed by a non-contacting posi-  
tion sensor (Non Contacting Position Sensor) directly at the actuator.  
This may correct the angle error of the stroke tap, compares the  
potemtiometer voltage as actual value x with the setpoint w fed in at  
the terminals 3 and 7 and calculates the manipulated variable  
increments Δy. Depending on the size and direction of the control  
error (x-w) the piezo-controlled supply air or exhaust air valve is  
opened. The volume of the actuator integrates the positioning  
increments to actuating pressure y open which moves the actuator bar  
or actuator shaft approximately proportionally. These positioning  
increments change the actuating pressure until the control error  
becomes zero.  
The pneumatic actuators are available in single and double-acting  
versions. Only one pressure chamber is aerated or deaerated in the  
single-acting version. The resulting pressure operates against a spring.  
In the double-acting version, two pressure chambers are counteractive.  
In this case the one volume is deaerated when the other volume is  
aerated. See the block diagram figure 2-10, page 25.  
The control algorithm is an adaptive predictive five-point switch  
(see figure 2-9, page 24).  
The valves are controlled with continuous contact at large control errors  
(fast step zone). At medium control errors the valve is controlled by  
pulse length modulated pulses (short step zone).  
No actuating pulses are output in the small control error zone (adaptive  
dead zone). The dead zone adaptation and the continuous adaptation  
of the minimum pulse lengths in automatic operation cause the best  
possible control accuracy to be achieved at the lowest switching fre-  
quency. The start parameters are determined during the initialization  
phase and stored in a non-volatile memory. These are basically the real  
travel with the mechanical limit stops, the travel times, the size of the  
dead zone etc.  
In addition the number of fault messages, changes in direction and the  
number of strokes are determined and stored every 15 minutes during  
operation. These parameters can be read out and documented by the  
communication programs such as PDM and AMS. Conclusions as to  
the wear on the fitting can be drawn (diagnostic function) especially by  
comparing the old value with the currently determined values.

2.5 HART-function  
Function  
The positioner is also available with built-in HART-functions. The HART  
protocol allows you to communicate with your instrument with a hand-  
held communicatorR, PC or programming unit. This enables you to  
configure your instrument comfortably, save configurations, call diag-  
nostic data, display online measured values and much more. Commu-  
nication takes place as frequency modulation over the existing signal  
lines for the command variable from 4 to 20 mA.  
The SPART PS2 is integrated in the following parameterization tools:

Operation on the positioner has priority over the settings via the HART  
interface.  
Communication is aborted by a power failure at the positioner.  
2.6 State as supplied  
There are no mechanical mounting accessories on the controller in the  
state as supplied. These must be ordered and installed according to  
the “operating instructions” depending on the application.  
The respective connections for single or double-acting versions are  
prepared at the factory as ordered.  
The pneumatic connections on the rear are sealed.

2.7.1 Installation of options modules in normal and intrinsically safe  
versions  
The following option modules are available for the positioner in the  
standard and the intrinsically safe version:  
-- ly-module  
-- Alarm module  
-- SIA-module  
-- Mechanical limit switch module  
-- EMC filter module  
The installation of the options modules is described below:  
Installation  
The option modules are secured by a assembly covering ((1), see  
figure 2-11, page 28) and mechanically fixed.  
NOTE  
.
To install the option modules the housing of the positioner needs to be  
opened. As soon as the positioner is opened, the IP66 degree of  
protection is not guaranteed.  
Open positioner  
To open the positioner, the four screws of the housing cover must be  
loosened with a Phillips screwdriver.  
Disconnect or isolate the power supply cables.  
Remove the module cover (1). To do this, the two screws (1.1) must be  
removed with a screwdriver.  
NOTE  
.
To prevent premature wearing of the fixture by the self-tapping screws  
(1.1), the following method of mounting the module cover (1) has  
proven effective.  
1. Turn the screws counterclockwise until you feel them snap into the  
thread  
2. Tighten both screws carefully in clockwise direction

-- Alarm module  
Installation  
The options modules are protected and mechanically fixed by a module  
cover ((1), see figure 2-12, page 31).

.
The housing must be opened to install the options modules. The  
degree of protection IP66/NEMA4x is not guaranteed as long as the  
positioner is open.  
WARNING  
!
In areas in which the atmosphere may be potentially explosive, the  
explosion-proof positioner may only be supplied with electrical auxiliary  
power when the housing is closed and when built-in, approved elec-  
tronics are used.  
The feed-though openings for the electronic connections must be  
sealed with EEX-d certified cable glands or EEx-d certified plugs or  
an ignition lock must be mounted at a maximum distance of 46 cm  
(18 inches) when using the “conduit”-system.  
Open the  
positioner  
See figure 2-12, page 31. Disconnect or isolate the power supply  
cables first.  
To open the positioner, the safety catch (12) must be opened and the  
screw-on cover unscrewed.  
After loosening the four fixing screws (13.1) the complete rack (13) can  
be removed. The actuator may have to be turned so that the clutch can  
be easily disengaged.  
Remove the module cover (1). To do this, the two screws (1.1) must be  
removed with a screwdriver.

2.7.4 Alarm module  
The alarm module contains  
S
S
3 digital outputs and  
1 digital input  
Function  
The digital outputs serve to output fault messages and alarms. The  
configuration is described in chapter 4.4, page 95, with the para-  
meters 44 to 54.  
By an external signal applied at digital input (DI2) the actuator can be  
blocked or driven to its limit positions for example depending on the  
configuration. The configuration is described in chapter 4.4, page 95,  
with the parameters 43.  
The alarm module is available in two versions:  
S
explosion protected for connecting to switching amplifier  
EN 60947-5-6  
S
non-explosion protected for connection to voltage sources with a  
maximum 35 V  
The semiconductor outputs of the alarm module report an alarm (signal  
state Low) by switching off with high resistance. They are conductive in  
the High state (without alarm). The dynamic control makes them error  
self-reporting.  
The outputs are potentially isolated from the basic circuit and each  
other.  
The digital input is double.  
S
S
one potential isolated for voltage level  
one not potential isolated for floating contacts  
These two inputs are designed as logic OR links.  
Installation  
Insert the alarm unit (4) below the motherboard in the rack up to the  
stop and use the 8-pin flat ribbon cable (5) to connect it to the mother-  
board (see figure 2-11, page 28).

2.7.5 SIA module  
The SIA module contains:  
S
S
one binary output  
two binary outputs  
Function  
A collected fault message (see alarme module) is output via the binary  
output. The floating digital output is implemented as a self error report-  
ing semiconductor output.  
The two binary outputs are used to report two mechanically adjustable  
limit values (L1, L2) via slot initiators. These two outputs are electrically  
independent of the rest of the electronics.  
Installation  
(Slot Initiator Alarm module) Proceed as follows for installation  
(figure 2-11, page 28)::  
1. Remove all the electrical connections from the motherboard (2).  
2. Loosen the two fixing screws (2.1) of the motherboard.  
3. Snap out the motherboard by carefully bending the four holders.  
4. Insert the SIA module (7) from above until it reaches the upper  
circuit board rail of the rack.  
5. Push the SIA module into the circuit board rail of the rack approx.  
3 mm towards the right.  
6. Screw the special screw (7.1) through the SIA module into the axle  
of the positioner (Torque: 2 Nm):  
CAUTION  
The pin pressed into the actuating disc bearing (12) must be adjusted  
to just before touching with the special screw. The actuating disc bea-  
ring and the special screw must then be turned simultaneously so that  
the pins slot into the special screw.  
7. Place the insulating cover (10) over the SIA module underneath  
the surface of the motherboard at the container wall on one side.  
The recesses in the insulating cover must slot into the correspond-  
ing lugs on the container wall. Place the insulating cover on the  
SIA module by carefully bending the container walls.  
8. Snap the motherboard into the four holders and screw it tight again  
with the two fixing screws (2.1).

9. Make all the electrical connections between the motherboard and  
the options with the ribbon cables provided and between the mo-  
therboard and potentiometers with the potentiometer cable.  
10. Fix the enclosed module cover instead of the standard version with  
the two screws (1.1).  
11. Select the plates which already exist on the standard version of the  
module cover from the set of plates enclosed. Stick the selected  
plates according to the standard version to the mounted module  
cover. In the case of the version which doesn’t feature explosion  
protection, stick the warning sign onto the side of the ground plate  
opposite the name plate.  
12. Make the electrical connections.  
Setting the two limit values:  
NOTE  
.
Connect a suitable display instrument such as the Initiator-Tester  
type 2/Ex made by Peperl+Fuchs to the terminals 41 and 42 or termi-  
nals 51 and 52 of the SIA module to be able to see the switching state  
of the slot initiators.  
1. Drive the actuator to the first desired mechanical position.  
2. Adjust the top actuating disc (7.2) by hand until the output signal  
on terminals 41 and 42 changes.  
3. Drive the actuator to the second desired mechanical position.  
4. Adjust the bottom actuating disc (7.3) by hand until the output sig-  
nal on terminals 51 and 52 changes.  
NOTE  
.
If you turn the actuating disc beyond the switching point up to the next  
switching point, you can set a high-low or a low-high change.  
To avoid the actuating discs being accidentally adjusted during opera-  
ting, they are relatively sluggish. The following remedy might be of help  
if you are having trouble with the adjustment: open and close the ac-  
tuator several times while holding the actuating discs. This temporarily  
reduces the friction. This allows an easier and finer adjustment.

S
S
A binary output for the output of a group error message)  
Two switches for signaling two limit values that can be set mechani-  
cally. These two switches are electrically independent from the rest  
of the electronic system.  
Installation  
The installation has to be carried as follows (figure 2-11, page 28):  
WARNING  
!
When the mechanical limit switch module is run with AC > 16 V or  
DC > 35 V (low voltage), the housing must be protected against  
mechanical actions of > 1 Joule, since otherwise the proper functioning  
of the IP66 protective system is not guaranteed.  
DANGER  
!
When the module is supplied with low voltage, you must observe the  
basic safety rules before beginning work on the device, such as:  
1. Deenergizing the module by disconnecting it via the disconnecting  
device located directly upstream from the module  
2. Securing it against being turned on again  
3. Ensuring that the module is disconnected from the voltage supply  
CAUTION  
The following maximal values only refer to the clamps 41 and 42 as  
well as the clamps 51 and 52.  
Maximal voltage (not Ex)  
Maximal current (not Ex)  
Maximal voltage (Ex)  
Maximal current (Ex)  
AC 250 V or DC 24 V  
AC/DC 4 A

DC 100 mA  
When you supply one circuit breaker with extra-low voltage (AC <16 V  
or DC 35 < V) and the other with low voltage, you ensure that the ca-  
ble insulation is doubled.  
When operating the switch with low voltage, you must position the low  
voltage circuits so that they are separated from the extra-low voltage  
circuits.

CAUTION  
The pin pressed into the actuating disc bearing (12) must be adju-  
sted just before it touches the special screw. In order that the pin  
slot into the special screw, you must then turn the actuating disc  
bearing and the special screw simultaneously  
7. Place the insulating cover (10) over the mechanical limit switch  
module underneath the surface of the motherboard onto the con-  
tainer on the wall. The recesses in the insulating cover must slot  
into the corresponding lugs on the container wall. Place the insulat-  
ing cover on the mechanical limit switch module by carefully bend-  
ing the container walls.  
8. Snap the motherboard board into the four holders and screw it tight  
again with the two fixing screws (2.1).  
9. Make sure all electrical connections between the motherboard and  
the options using the ribbon cables provided and between the mo-  
therboard and potentiometer using the potentiometer cable.  
10. Fix the enclosed module cover (1) instead of the standard version  
using the two screws (1.1).  
NOTE  
.
To prevent premature wearing of the fixture by the self-tapping screws  
(1.1), the following method of mounting the module cover (1) has pro-  
ven effective:

General  
WARNING  
!
To avoid injury or mechanical damage to the positioner/mounting kit,  
the following order must be observed for assembly:  
1. Mechanical fitting of positioner  
this chapter  
2. Connection of electric power supply  
see chapter 3.4, p. 57  
3. Connection of pneumatic power supply see chapter 3.5, p. 71  
4. Put into operation  
see chapter 3.6, p. 72  
Please also observe the warning on page 58!  
SIPART PS2 Manual  
A5E00074631--06

Preparing for Operation  
NOTE  
.
The positioner will be equipped at the factory and delivered complete  
with the necessary options at the customer’s request. Options modules  
may only be retrofitted by our service technicians.  
The positioner must be assembled – especially in a moist environment  
– in such a way as to rule out freezing of the positioner axle at low  
ambient temperature.  
The operating keys must be covered to prevent liquid getting in.  
WARNING  
!
In the combination of components it must be ensured that only  
positioners and options modules are combined which are approved  
for the respective area of application. This applies especially for safe  
operation of the positioner in areas in which the atmosphere is poten-  
tially explosive (zone 1 and 2). The instrument categories (2 and 3) of  
the instrument itself and those of its options must be observed.  
In addition, you must always make sure that no water gets into an open  
housing or screw-type gland. This may be the case for example when  
the positioner cannot be finally assembled and connected immediately.  
It generally applies that the positioner may only be operated with dry  
compressed air. Therefore use the normal water traps. An additional  
drying unit may even be necessary in extreme cases. This is particu-  
larly important when operating the positioner at low ambient tempera-  
tures. Please set the purge air switch (on the valve block above the  
pneumatic terminals) additionally to the “OUT” position.  
Use a sufficiently rugged console (e.g. plate thickness > 4 mm with  
reinforcements) for part-turn actuators and the mounting kit “linear  
actuator” or integrated connection for linear actuators.  
3.3.1 Instructions for using positioners in a wet environment  
This information gives you important instructions for the assembly and  
operation of the positioner in a wet environment (frequent, heavy rain  
and/or prolonged tropical condensation) in which the IP66 degree of  
protection is no longer sufficient and especially when there is a danger  
that water may freeze.  
To prevent water getting into the instrument in normal operation (e.g.  
through the exhaust air openings) or the display being poorly legible,  
please avoid the unfavorable installation positions illustrated in  
figure 3-5.

Figure 3-5  
Favorable and unfavorable installation positions  
If conditions oblige you to operate the positioner in a unfavorable  
installation position, you can take additional precautionary measures to  
prevent penetration by water.  
NOTE  
.
Never clean the positioner with a high pressure water jet because the  
IP66 degree of protection is inadequate protection for this.  
The necessary additional measures to prevent penetration by water  
depend on the installation position chosen and you may additionally  
require:

S
screw-type gland with sealing ring (e.g. FESTO: CK –1 / 4–PK–6)  
plastic hose approx. 20 to 30 cm (e.g. FESTO PUN- 8X1,25 SW)  
cable straps (number and length depends on local conditions)  
Procedure  
S
Connect the pipes in such a way that rain water which runs along  
the pipes can drip off before it reaches the terminal strip of the posi-  
tioner.  
S
S
Check the electrical connections for perfect firm contact.  
Check the seal in the housing cover for damage and contamination.  
Clean and replace if necessary.  
S
Mount the positioner if possible so that the sinter bronze silencer  
faces downwards on the underside of the housing (vertical installa-  
tion position). If this is not possible, the silencer should be replaced  
by a suitable screw-type gland with a plastic hose.

Make sure that the hose has no kinks and the exhaust air can flow  
out unhindered.  
3.3.2 Instructions for using positioners which are exposed to strong  
accelerations or vibrations  
NOTICE  
for explosion-proof versions:  
Only adjust the outer friction clutch (8, Fig. 2-12, page 31). The internal  
friction clutch (8, Fig. 2-11, page 28) is fixed and, for the explosion-  
proof version, must not be adjusted.  
The electro-pneumatic positioner SIPART PS2 has a friction clutch and  
switchable gearing and can thus be used universally for part-turn and  
linear actuators. This means that, for part-turn actuators you don’t have  
to worry about the zero point and for linear actuators, you don’t have to  
worry about symmetrical mounting, as you can adjust the working  
range after installation, with the help of the friction clutch.  
The switchable gearing allows you to also adjust the positioner for  
small or large lifts.  
Occasionally it can happen, that in the rough environment of process  
systems (e.g. due to incorrectly fitted valves or if “steam pulses” occur)  
that the shaft to monitor the position of the SIPART PS2 positioner is  
exposed to extreme acceleration, which far exceeds its specified load  
limits, and which could result in an unwanted shift in the friction clutch  
or in the gears in the position monitoring jumping briefly out.  
For cases like this, as standard, the SIPART PS2 positioner is fitted  
with a locking device for the friction clutch and you can also lock the  
setting of the transmission ratio selector. This means that an unwanted  
change to the position monitoring due to the above mentioned effects  
can be reliably prevented.  
Both of these locking options are labeled via additional tags inside the  
device (see Figure 3-6, page 47). Note that these locks are only re-  
quired if extreme acceleration or strong vibration might be present  
within your process.  
SIPART PS2 Manual  
A5E00074631--06

Preparing for Operation  
Procedure  
After you have installed the positioner and put it fully into operation, you  
can set the torque for the friction clutch as follows:  
S
On the module cover, insert an ordinary 4 mm wide screwdriver into  
a slot on the yellow wheel.  
S
Now use the screwdriver to move the yellow wheel to the left, until  
you can feel that it clicks in. This increases the torque of the friction  
clutch.  
S
S
You can recognize a locked friction clutch by an approx. 1 mm wide  
gap between the yellow and black wheels.  
If you have to set the zero pint e.g. after exchanging the actuator,  
first reduce the torque by turning the yellow wheel to the right until  
you hit the stop. After setting the zero point, you can refix the friction  
clutch as described above.  
Starting from the neutral setting (as delivered), you can lock the trans-  
mission ratio selector as follows:  
S
Adjust the yellow wheel underneath the terminals with an ordinary  
4 mm wide screwdriver to correspond to the setting that you would  
like (33_ or 90_), turning to the left or right, until you can feel that it  
clicks in.  
S
Please note that you can only adjust the transmission ratio selector  
after releasing the fixing.  
For this reason you first have to put the yellow ring into the neutral  
position, if you have to adjust the transmission ratio selector  
e.g. after exchanging the actuator).

Applications in which the measures described above are inadequate  
are also conceivable. This applies for instance with continuous and  
heavy vibration, increased or too low ambient temperatures and in the  
case of nuclear radiation.  
The separate attachment of position displacement sensor and  
controller unit can help here. A universal component is available which  
is suitable both for linear and part-turn actuators.  
You require the following:  
S
The external position detection system (order no.  
C73451-A430-D78). This consists of a SIPART-PS2-housing with  
integrated friction clutch, built-in potentiometer and various dummy  
plugs and seals.  
S
S
S
or a Non-Contacting Position Sensor (e.g. 6DR4004-6N).  
The controller unit, any positioner version.  
The EMC filter module, this is is a set together with cable clips  
and M-20 screw-type cable gland and has the order number  
C73451-A430-D23. The EMC filter module must be installed in the  
positioner. The installation instructions enclosed with the EMC filter  
module explain how to assemble the components.  
S
A 3-wire cable for connecting the components.  
This EMC filter module should always be used for the controller unit  
when any actuator-mounted potentiometer (resistance 10 kΩ) is to  
be used instead of the position detection system C73451-A430-D78.  
WARNING  
!
The explosion-proof version may not be run together with the external  
position detection system.

and fix with the hexagon socket cap screw (17).  
7. Fit the mounting bracket (1) with two hexagon head screws (9),  
lock washer (10) and flat washer (11) on the rear of the positioner.  
8. Selection of the row of holes depends on the width of the actuator  
yoke. The pin (4) should engage in the pick-up bracket (2) as close  
as possible to the spindle but may not touch the clamping  
assembly.  
9. Hold the positioner with the mounting bracket on the actuator so  
that the pin (4) is guided within the pick-up bracket (2).  
10. Tighten the pick-up bracket.  
11. Position the mounting parts according to the type of actuator.  
-- Actuator with ledge: Hexagon head screw (8), flat washer (11)  
and lock washer (10).  
-- Actuator with plane surface: Four hexagon head screws (8), flat  
washer (11) and lock washer (10).  
-- Actuator with columns: Two U bolts (7), four hexagon nuts (21)  
with flat washer (11) and lock washer (10).  
12. Secure positioner onto the yoke using the previously positioned  
mounting parts.  
NOTE  
.
Set the height of the positioner so that the horizontal lever position is  
reached as close to the stroke center as possible. You can use the  
lever scale as orientation. It must be guaranteed that the horizontal  
lever position is passed through within the stroke range.

centering hole.  
3. Push the coupling wheel (2) onto positioner axis, pull back by  
about 1 mm and tighten the hexagon socket head screw (18) with  
the Allen key provided.  
4. Place the carrier (3) onto the end of the actuator and secure using  
Fillister head screw (16) and washer (17).  
5. Carefully place positioner with mounting console onto the actuator  
such that the pin of the coupling wheel engages in the actuator.  
6. Align the positioner/mounting console assembly in the center of the  
actuator and screw tight.  
(Screws not included in delivery; they are part of the actuator  
mounting console!)  
7. Following startup as described in Chapter 3.6, page 72: Drive the  
actuator to the end position and adhere scale (4.1) on the coupling  
wheel (2) according to direction of rotation and part-turn actuator.  
The scale is self--adhesive!

3.4 Electrical Connection  
NOTE  
.
Any necessary options modules must be installed before electrical  
connection (see chapter 2.7, page 27).  
N.B.: The transmission ratio selector can only be set when the  
positioner is open. Therefore check this setting before closing the  
controller.  
WARNING  
!
The specifications of the examination certificate valid in your country  
must be observed.  
Electrical connection in hazardous areas  
The national directives and laws which apply in your country for haz-  
ardous areas, must be followed for electrical installations. In Germany  
these are, for example:  
--  
--  
Working reliability regulations  
Regulations for installing electrical equipment in hazardous areas,  
DIN EN 60079-14 (in the past VDE 0165, T1).  
--  
The EC type examination certificates  
SIPART PS2 Manual  
A5E00074631--06  
57  
Preparing for Operation  
WARNING  
!
If the intrinsically safe version is operated with a higher operating vol-  
tage by mistake, the positioner must no longer be used for intrinsically  
safe application.  
The explosion-proof positioner may only be supplied with electrical  
power in areas in which the atmosphere may be potentially explosive  
when the housing is closed. Where power supply is required, we  
recommend checking the power supply to ensure that it corresponds  
with that on the name plate and with the test certification valid for your  
country.  
The feed-though openings in the explosion-proof version for the  
electronic connections must be sealed with EEX-d certified cable  
glands or EEx-d certified plugs or an ignition lock must be mounted at  
a maximum distance of 46 cm (18 inches) when using the “conduit”-  
system.  
The plastic housing is metal lined to increase the electromagnetic  
compatibility (EMC) against high frequency radiation. This screen is  
connected electrically to the threaded bushes shown in figure 3-12,  
page 58.  
Please bear in mind that this protection can only be effective if you con-  
nect at least one of these bushes with grounded fittings by electrically  
conductive (blank) mounting parts.  
Shield  
Figure 3-12 Base plate  
SIPART PS2 Manual  
A5E00074631--06  
58  
Preparing for Operation  
NOTE  
.
Use standard M20 x 1.5 cable gland nuts to ensure leakage (IP-protec-  
tion of the housing) and for the necessary tensile strength use only  
cables with a cable diameter ≥ 8 mm, or for smaller diameters use a  
suitable sealing insert.  
For the NPT version, the positioner will be delivered with an adapter.  
Make sure that when fitting a part into the adapter, that the maximum  
permissible torque of 10 Nm is not exceeded.  
NOTE for use in zone 2:  
Non-sparking equipment for Zone 2 may not be connected or discon-  
nected under power in normal operation.  
However, during installation or repair work the positioner may be con-  
nected or disconnected even under power (see also certificate for  
zone 2).  
NOTE for use in two-wire systems:  
Never connect the current input (terminal 6 and 7) to a voltage source  
as this could destroy the positioner.  
Always use a current source with a maximum output current of 20 mA.  
To maintain the power supply, the input current must be ≥3.6 mA.

Connect supply air to PZ.  
NOTE  
.
In order for spring-loaded pneumatic actuators to be able to reliably  
exploit the maximum possible travel, the supply pressure must be  
sufficiently greater than the maximum required final pressure of the  
actuator.  
After installing the device, check the pneumatic connections of the entire  
assembly for leakage. Any leakage would cause not only continuous  
consumption of compressed air but also would cause the positioner to  
continually endeavor to compensate for the variance in position, leading  
in time to premature wear of the whole control mechanism.

3.6 Commissioning  
Once the positioner has been fitted to a pneumatic actuator, it must be  
provided with electrical and pneumatic auxiliary power.  
Then you can then adapt the position controller to the respective actua-  
tor by parameterizing and initializing it.  
Mode” operating mode (which can also if necessary be attained by  
“PRST”) -- “NOINI” will flash.  
If the positioner has not been initialized it will be in the “P Manual  
Mode“ operating mode (which can also if necessary be attained by  
“PRST”) -- “NOINI“ will flash.  
This initialization can be effected in three different ways:  
S
Automatic initialization  
Initialization takes place automatically. Hereby the positioner deter-  
mines the direction of action, the stem travel and the angle of rota-  
tion, the travel times of the actuator one after the other and adapts  
the control parameters to the dynamic behavior of the actuator.  
S
S
Manual initialization  
The stem travel or angle of rotation of the actuator can be set  
manually, the other parameters are determined as in automatic init-  
ialization. This function is useful in actuators with soft limit stops.  
Copying initialization data (positioner exchange)  
In the devices with HART function the initialization data of a posi-  
tioner can be read out and copied to another positioner. This en-  
ables a defective device to be changed without having to interrupt  
an ongoing process by initialization.  
Only a few parameters need to be set in the positioner prior to initializa-  
tion. The others are defaulted so that they do not normally need to be  
adjusted. You will have no problems with commissioning if you observe  
the following points.  
The possible operating modes and parameters, together with the  
adjustment capabilities and their effects are described in chapter 4,  
page 89 “Operation“.  
NOTE  
.
N.B.: The operating pressure should be at least one bar greater than is  
necessary for closing/opening the valve during initialization. However,  
the operating pressure may not be higher than the maximum permis-  
sible operating pressure of the actuator.  
N.B.: The transmission ratio selector can only be set when the  
positioner is open. Therefore check this setting before closing the  
housing.

3.7 Copying initialization data (positioner exchange)  
With this function you have the possibility of starting up a positioner  
without running the initialization routine. This allows for example a posi-  
tioner to be changed on a running system in which automatic or manual  
initialization cannot be performed without disturbing the process.  
NOTICE  
Initialization (automatic or manual) should be performed as soon as  
possible afterwards because only then can the positioner be optimally  
adapted to the mechanical and dynamic properties of the actuator.  
Data are transmitted from the positioner to be replaced to the  
replacement instrument via the HART®- communication interface.  
The following steps must be performed to exchange a positioner:  
1. Read in and save instrument parameters and initialization data  
(determined in initialization) of the instrument to be replaced with  
PDM (Process Device Manager). This step is unnecessary if the  
instrument has been parameterized with PDM and the data have  
already been stored.  
2. Fix the actuator in its momentary position (mechanical or  
pneumatic).  
3. Read and note the current position actual value of the positioner to  
be changed. If the electronics are defective, determine the current  
position by measuring on the actuator or valve.  
4. Disassemble the positioner. Mount the lever arm of the positioner  
on the replacement instrument. Mount the replacement instrument  
on the fitting. Move the transmission ratio selector to the same  
position as the defective instrument. Copy the instrument data and  
initialization data from the PDM or handheld.  
5. If the displayed actual value does not match the noted value of the  
defective positioner, set the correct value with the friction clutch.  
6. The positioner is now ready to operate.  
The accuracy and dynamic behavior may be restricted in relation  
to correct initialization. The position of the hard stops and the rela-  
ted maintenance data may show deviations in particular. Therefore  
initialization must be performed at the earliest opportunity.

The following chapter describes the operation of the positioner.  
4.1 Display  
The LC display has two lines whereby the lines have different  
segmentation. The elements of the top line consist of 7, those of the  
bottom line of 14 segments. The contents of the display depend on the  
selected operating mode (see chapter 4.3, page 92)  
NOTE  
.
If the positioner is operated in ranges with temperatures below --10 °C  
the liquid crystal display becomes sluggish and the display refresh rate  
is reduced considerably.  
Figure 4-1 shows you the various display options. The meaning of fur-  
ther display capabilities is detailed in chapter 4.3 page 139.  
4.2 Input keys  
The positioner is operated by three keys (figure 4-2, page 91) the  
function of which depends on the selected operating mode. In the  
explosion proof version of the positioner the input keys are underneath  
a key cover which can be lifted up after loosening the cover screw.  
NOTE  
.
The input keys of the explosion proof version must be covered to  
prevent liquid getting in. The IP66/NEMA4x degree of protection is not  
guaranteed when the housing is open or the key cover is open.  
The housing cover must be removed to operate the keys in the normal  
and intrinsically safe versions of the positioners.

Operation  
The display of the positioner shows you the current potentiometer  
P-manual mode  
(ex-factory state)  
setting in the top line and “NOINIT” flashes in the second line. You can  
move the actuator with the decrement and increment key . In order  
to adapt the positioner to your actuator, you have to change to the  
Configuration menu. See also chapter 3.6, page 72 “Commissioning”.  
Output of alarms and position feedback is possible after successful init-  
ialization.  
Configuration and  
initialization  
To go to the Configuration menu, press the operation mode key  
at least 5 seconds. In the Configuration menu you can adapt the  
for  
positioner individually to your actuator and start initialization. Only a few  
parameters need to be set in the positioner prior to initialization. The  
others are defaulted so that they do not normally need to be adjusted.  
You can block the Configuration menu against manipulation by an  
appropriately parameterized and activated digital input. Which  
parameters you need to set and all other parameters are explained in  
chapter 4.4, page 95 Parameters.  
The configuration mode can be reported by outputting a  
parameterizable fault message, a position feedback or output of limit  
values A1 and A2 is not possible.  
NOTE  
.
If the electric power supply fails during configuration, the positioner  
switches back to the first parameter after recovering the power supply,  
values which have already been parameterized are retained. When  
doing this, please note that the new value will only be saved when  
leaving the configuration menu or when another parameter is selected.  
Without a power failure you re-enter the configuration menu at the  
point you exited it when you call the Configuration menu again.

In this operating mode you can move the actuator with the decrement  
) and increment keys ( ) and the current position is held regard-  
(
less of the setpoint current and any leakages.  
NOTE  
.
You can move the actuator quickly by pressing the other direction key  
additionally whilst keeping the direction key selected first pressed.  
The manual mode can be reported by outputting a parameterizable  
fault message, a position feedback or output of limit values A1 and A2  
is only possible in automatic mode.  
NOTE  
.
The positioner switches over to automatic mode automatically after an  
electrical power failure.  
Automatic (AUT)  
The automatic mode is the normal mode. In this mode the positioner  
compares the setpoint current with the current position and moves the  
actuator until the control deviation reaches the parameterizable dead  
zone. Error messages are output if this is not possible for various  
reasons.  
Diagnostic display  
In this operating mode you can have the current operating data (such  
as number of strokes, number of changes in direction, number of faults  
messages, etc.) displayed (see table 4-1, page 123).  
From the automatic or manual mode you go to the diagnostic display  
by simultaneously pressing all three keys for at least two seconds.

Operation  
See chapter 4.5, page 122 for further information.  
NOTE  
.
The respective operating mode (MAN or AUT) of the positioner is retai-  
ned when you switch to the diagnostic display, i.e. in automatic opera-  
tion the specified setpoint is still used for controlling and in manual  
operation the position last reached is retained.  
4.4 Parameters  
All the parameters of the positioner are listed in this chapter. Figure 4-6  
shows an overview of the parameters.  
The parameter name is shown once in plain text and once as it ap-  
pears in the display. The function of the parameter is described briefly  
in the “Function” column. In addition, the possible parameter values,  
the physical unit and the factory setting of the parameters are shown.

Operation  
Normally adjustment of the first three following parameters is com-  
pletely sufficient to enable a positioner to be operated by an actuator.  
If you wish to become familiar with all details of the positioner, try out  
incrementally the effects of the remaining parameters by selective  
trials.  
NOTE  
.
In particular if the positioner has previously been operated using a  
different actuator, it must always be reinitialized in order to restore the  
factory settings. Only in this way can the positioner matching process  
start from known conditions. The parameter “55.PRST” is provided for  
this purpose.  
This is also recommended if multiple parameters have been changed  
in a single session, the effects cannot be assessed and unintended  
consequences may result.  
1.YFCT  
Positioning actuator type  
This is to match the positioner with the respective actuator and where  
necessary to the position sensor being used. The following adjustment  
capabilities are provided:  
S
S
YFCT = turn  
This adjustment is necessary for the part-turn actuator.  
If “turn” is selected, the following parameter “2. YAGL” is automati-  
cally set to 90_ and cannot be changed.  
YFCT = WAY (Factory setting)  
This is necessary for a linear actuator. This allows the positioner to  
compensate for the non-linearity that arises due to the conversion of  
the linear movement of the linear actuator into the part-turn move-  
ment of the feedback shaft. For this the positioner is factory set so  
that it shows between “P 49.0 and P 51.0” when the arm on the  
feedback shaft is vertical to the linear actuator spindle.  
S
YFCT = LWAY  
This must be adjusted, if an external linear potentiometer is to be  
connected to a linear actuator.  
TIP: use this adjustment also for part-turn actuators with reverse  
direction of control action.  
S
S
YFCT = ncSt  
Use this when an NCS is fitted to a part-turn actuator.  
YFCT = -ncSt  
This must be set when an NCS is used with a part-turn actuator with  
reverse direction of control action.  
S
YFCT = ncSL  
This must be set when an NCS is used with a linear actuator.  
SIPART PS2 Manual  
A5E00074631--06  
98  
Operation  
S
YFCT = ncSLL  
This must be adjusted if an NCS is to be connected to a linear ac-  
tuator with the position converted by an arm into a part--turn move-  
ment.  
NOTE  
.
After “LWAY, ncSt, --ncSt or ncSL” have been adjusted, the parameter  
“3. YWAY” will not be displayed.  
2.YAGL  
Rated angle of rotation of the feedback shaft  
In part-turn actuators, an angle of 90° is preset automatically by  
1.YFCT = turn (see above). In linear actuators (1.YFCT = WAY) a  
value of 33° or 90° can be selected depending on the stroke range:  
S
S
33° for strokes ≤ 20 mm  
90° for strokes > 20 mm  
When using the lever up to 35 mm, both angles of rotation (33° and  
90°) are possible.  
The long lever (> 35 mm stroke) is only designed for an angle of  
rotation setting of 90°. It is not part of the mounting kit set 6DR4004-8V  
but must be ordered separately under order number 6DR4004-8L.  
NOTE  
.
The setting of the transmission ratio selector on the positioner (see  
figure 2-2, page 17 and figure 2-3, page 18) must correspond to the  
angle value selected under “2.YAGL”.  
3.YWAY  
Lever arm transmission  
Selection of the lever arm range: serves to display the real stroke after  
initialization. The use of this parameter is optional. You only need to set  
this parameter if you want to have the way in mm displayed at the end  
of the initialization.  
If the parameter value “oFF” is selected here, the real stroke is not  
displayed after initialization.  
NOTE  
.
The specification “YWAY” must match the mechanical lever arm trans-  
mission. The carrier must be set to the value of the actuator stroke,  
if this is not scaled to the next highest scaled value.

Operation  
4.INITA  
Automatic initialization (see chapter 3.6, page 72)  
By selecting “Strt” and pressing the increment key  
for at least  
5 seconds, automatic initialization is started. The initialization process  
is displayed by “RUN 1” to “RUN 5” (see figure 3-35, page 83 to  
figure 3-38, page 86).  
5.INITM  
Manual initialization  
By selecting “Strt” and pressing the increment key  
for at least  
5 seconds, manual initialization is started. The manual initialization  
process is described in chapter 3.6.3, page 76 and chapter 3.6.6,  
page 81.  
NOTE  
.
If the positioner has already been initialized, for INITA and INITM it is  
possible to transfer it to its non-initialized state without changing the  
remaining parameters by pressing the decrement key  
for 5 s.  
6.SCUR  
7.SDIR  
Current range of the setpoint  
The selection of the current range depends on the connection type.  
“0mA” (0 to 20 mA) is only possible in three-/four-wire connections (see  
figure 3-23, page 64).  
Setpoint direction (see figure 4-8, page 101)  
The setting of the setpoint direction serves to reverse the direction of  
action of the setpoint. It is used mainly for the split range mode and in  
single-acting actuators with the safety position “up”.  
8.SPRA  
9.SPRE  
Split range start (see figure 4-8)  
and  
Split range end (see figure 4-8)  
The parameters “8.SPRA” and “9.SPRE” in connection with the  
parameter “7.SDIR” serve to restrict the active setpoint range. In this  
way split range tasks can be solved with the following characteristics.

10.TSUP  
11.TSDO  
Setpoint ramp UP  
and  
Setpoint ramp DOWN  
The setpoint ramp is effective in automatic operation and limits the  
speed of alteration of the active setpoint. When switching over from  
manual operation to automatic the active setpoint is adjusted to the set-  
point on the positioner with the setpoint ramp.  
This bumpless manual/automatic switchover avoids excessive pressure  
increases on long pipelines.  
In the position TSUP = Auto the slower of the two travel times deter-  
mined during initialization is used for the setpoint ramp. TSDO is then  
ineffective.

Operation  
34.DEBA  
Dead zone of the controller  
At dEbA = AUto the dead zone in automatic operation is adapted con-  
tinuously to the requirements of the control circuit. The dead zone is  
gradually increased on detecting a control oscillation. The reverse  
adaptation takes place by a time criterion.  
In the other discrete settings the fixed value is used for the dead zone.  
35.YA  
36.YE  
Manipulated variable limiting start (see figure 4-9 and 4-10)  
and  
Manipulated variable limiting end (see figure 4-9 and 4-10)  
With the parameters “YA” and “YE” the mechanical actuating distance  
(from stop to stop) is limited to the set values. In this way the mechani-  
cal setting range of the actuator can be limited to the active flow and  
the integral saturation of the commanding controller avoided.  
NOTE  
.
YE must always be set to greater than YA.  
37.YNRM  
Manipulated variable standardization (see figure 4-9 and 4-10)  
With limiting of the manipulated variable (by “35.YA” and “36.YE”) two  
different scalings are produced for the display and the position feed-  
back via the current output (MPOS or FLOW).  
The MPOS scaling shows the mechanical position (0 to 100%) be-  
tween the hard stops of the initialization. This is not affected by the pa-  
rameters “35.YA” and “36.YE”. The parameters “35.YA” and “36.YE”  
are displayed in the MPOS-scale.  
The FLOW-scale is the standardization (0 to 100%) to the range be-  
tween “35.YA” and “36.YE”. The setpoint w (0 to 100%) is always re-  
ferred to this range. This gives (also by using valve characteristics) a  
quasi-flow-proportional display and position feedback Iy.  
To calculate the control difference, the setpoint is also shown in the ap-  
propriate scale on the display.

Manipulated variable direction of action  
The direction of action (rising or falling) of the display and the position  
feedback (Iy) can be set with this.  
Tight closing with manipulated variable (see figure 4-9, page 102)  
With this function the valve can be driven to the seat with the maximum  
actuating force of the actuator (continuous contact of the piezo-valves).  
The tight closing function can be activated on one side or for both limit  
positions. YCLS becomes active when the setpoint is below the value  
set with parameter “YCDO” or above that set with parameter “YCUP”.

NOTE  
.
If the control function to close tightly is activated, for parameter  
“49. LIM” the monitoring of the control deviation in each overrun direc-  
tion (YCDO: < 0 %, YCUP: > 100 %) is disabled. This function is par-  
ticularly useful for valves with a soft seating. For long term monitoring  
of the end-stop positions, we recommend activating the parameters  
“52. ZERO” and “53. OPEN”.

NOTE  
.
“40.YCDO” must always be set to less than “41.YCUP”. The tight  
closing function has a fixed hysteresis of 1 %. “40.YCDO” and  
“41.YCUP” relate to mechanical stops and are independent of the  
settings of “7.SDIR” and “38.YDIR”.

The actuator can report the exceeding (max.) or dropping below (min)  
of a specified stroke or angle of rotation. The response of the alarms  
(limit values) is related to the MPOS-scaling (see figure 4-10,  
page 104). The alarms are reported by the alarm module (order no.  
6DR4004-6A or -8A). In addition the alarms can be read out through  
the HART interface (optional).  
The direction of action of the digital outputs can be adapted from high  
active to low active sequence systems.

48. TIM  
Monitoring time for setting the fault messages  
The set value(s) is/are for the specification of the time, within which the  
positioner must have reached a compensated state. The corresponding  
response threshold is preset with “49. LIM”.  
If the set time is exceeded, the fault message output is set.  
NOTE  
.
If the tight closing function is activated, for parameter “49. LIM”, the  
monitoring of the control deviation in each overrun direction (YCDO:  
< 0 %, YCUP: > 100 %) is deactivated. This function is particularly  
useful for valves with a soft seat. For the long-term monitoring of the  
endstop positions, we recommend activating the parameters  
“F. ZERO” and “G. OPEN”.  
You can find more information on fault messages in chapter 4.5.3  
Online Diagnostics.  
49. LIM  
Response threshold for fault messages  
A value (%) can be set here for the permissible control deviation for  
triggering the fault message.  
If parameters 48 and 49 are set to “Auto” (factory setting), the fault  
message is set if the short step zone is not reached within a certain  
time. Within 5 to 95 % of the actuator travel, this time is 10 to 90 % of  
10 times the initialization actuating time.  
50.PRST

the range of 0.1 to 10.0%. That means, with a start position of e.g. 50%  
and a start tolerance of 2%, a partial stroke test can only be triggered  
during operation if the current position is between 48 and 52%.  
A3.STEP  
Step height  
Input of the step height of the partial stroke test within the range of  
0.1 to 100.0%. The factory setting is 10.0%.  
A4.STEPD  
Step direction  
Input of the step direction of the partial stroke test. The following  
options are available:  
“up”, “do” (down), “up do” (up and down). If “up” is selected, the  
actuator is moved in a controlled manner from its start position to the  
target position (start position + step height) and then back to the  
original position in a controlled way once the target position has been  
reached. The procedure for the “do” option is the same but in the  
opposite direction. With “up do”, the actuator first travels in a controlled  
manner from its start position to the upper target position (start position  
+ step height), then controlled from the upper to the lower target  
position (start position -- step height). After reaching the lower target  
position, it returns to its original position in a controlled manner.  
A5.INTRV  
Test interval  
Input of the interval for the cyclic partial stroke test within the range of  
one day to 365 days.

A6.PSTIN  
Partial stroke test reference step time  
(PSTIN = Partial Stroke Test Initialization)  
Measurement of the reference step time for the partial stroke test. After  
the initialization of the device, the calculated (C = calculated) average  
actuating time of the control valve is displayed in seconds in the form:  
C ###.#. This time can be used as reference step time, however it is  
only a rough guide value.  
That is why it is recommended to measure the reference step time here  
after the specification of the partial stroke test (parameters A1 to A5)  
by pressing the Greater Than button for five seconds. In doing so,  
“rEAL” is shown in the display. The device then automatically moves to  
the set start position, performs the desired step and saves the time  
required to do this. The time that is measured is the controlled  
movement from start position to target position. After the succesful  
measurement, this reference step time is shown in the display in the  
form: “###.#” seconds.  
If a reference step is attempted without previous initialization of the  
device, “noini” appears in the display. If the start position cannot be  
approached or if the jump destination cannot be reached, “Fdini“  
(Failed PST Initialization) is displayed.  
A7.FACT1  
A8.FACT2  
A9.FACT3  
Factor 1  
Input of the factor for the threshold 1 error message. The factor 1  
refers to the reference step time. If a specified partial stroke test results  
e.g. in a reference step time of 1.0 second and factor 1 is used in the  
factory setting of 1.5, the threshold 1 error message of the partial  
stroke test is performed for a measuring time of 1.5 seconds.  
Factor 2  
Input of the factor for the threshold 2 error message. The factor 2  
refers to the reference step time. If a specified partial stroke test results  
e.g. in a reference step time of 1.0 second and factor 2 is used in the  
factory setting of 3.0, the threshold 2 error message of the partial  
stroke test is performed for a measuring time of 3.0 seconds.  
Factor 3  
Input of the factor for the threshold 3 error message. The factor 3  
refers to the reference step time. If a specified partial stroke test results  
e.g. in a reference step time of 1.0 second and factor 3 is used in the  
factory setting of 5.0, the threshold 3 error message of the partial  
stroke test is performed for a measuring time of 5.0 seconds. At the  
same time, if this time threshold is exceeded, the excitation signal of  
the actuator is cancelled to prevent any sudden breaking free and  
overshooting of a valve that might be jammed or rusted in place.  
The partial stroke test is thus stopped immediately, a threshold 3 error  
is reported and the actuator is moved back to its original position.

b. DEVI  
General control valve malfunction  
This parameter activates the dynamic monitoring of the control valve  
reaction. To do this, the actual position sequence is compared to the  
guide value and the expected position sequence, which allows  
conclusions with regard to the correct operational behavior of the  
control valve.  
When the parameter is activated, the submenu for the general control  
valve malfunctions from b1 to b5 opens. The function can be  
configured there.  
b1.TIM  
Time constant of the low-pass filter  
The time constant of the low-pass filter is determined during the  
automatic initialization of the device. In the factory setting, parameter  
b1 therefore indicates “Auto”.  
If the user is very familiar with the process sequence or desires a  
certain filter time constant for application-specific reasons, parameter  
b1 can be set from one second to 400 seconds manually. One second  
causes no damping, 400 seconds result in a strong damping effect.  
b2.LIMIT  
Limit for the general control valve malfunction  
Sets the limit for the deviation from the model behavior. This limit is a  
reference value for the error message factors. Factory setting is 1.0 %.  
b3.FACT1  
Factor 1  
Input of the factor for the threshold 1 error message. This factor refers  
to the limit for the general control valve malfunction. Factory setting for  
factor 1 is 5.0. That means, for b2.LIMIT = 1.0% and factor 1 = 5.0, the  
first error message is triggered at a control deviation of 5.0 % from the  
model behavior.  
b4.FACT2  
b5.FACT3  
Factor 2  
Input of the factor for the threshold 2 error message. This factor refers  
to the limit for the general control valve malfunction. Factory setting for  
factor 2 is 10.0. That means, for b2.LIMIT = 1.0% and factor 2 = 10.0,  
the second error message is triggered at a control deviation of 10.0 %  
from the model behavior.  
Factor 3  
Input of the factor for the threshold 3 error message. This factor refers  
to the limit for the general control valve malfunction. Factory setting for  
factor 3 is 15.0. That means, for b2.LIMIT = 1.0% and factor 3 = 15.0,  
the third error message is triggered at a control deviation of 15 % from  
the model behavior.

Operation  
C. LEAK  
Pneumatic leakage  
This parameter is used to activate the function for the detection of a  
pneumatic leakage. To do so, the changes of position and the internally  
used controller output are recorded and filtered, depending on the  
direction. The filter result provides a coefficient that allows the detection  
of any leakage.  
Note that the detection of a leak can only provided clear results for  
spring-loaded actuators.  
C1.LIMIT  
Limit for the leakage indicator  
Sets the limit for the leakage indicator The leakage indicator is scaled  
within the range of 0.0 to 100.0. Factory setting for the limit is 30.0.  
In other words, there is leakage below this limit. A leak can be  
expected if this value is exceeded.  
To be able to make full use of the sensitivity of the detection process,  
it is recommended to perform a ramp test with a calibrator after the  
automatic initialization of the device. The ramp should cover the  
standard operating range of the valve and correspond in steepness to  
the approximate dynamic requirements of the application. During the  
ramp test, parameter 15.ONLK of the diagnosics menu provides  
information on the values shown by the leakage indicator. This allows  
the limit for the leakage coefficient to be defined above the maximum  
ramp test value.  
C2.FACT1  
C3.FACT2  
C4.FACT3  
Factor 1  
Input of the factor for the threshold 1 error message. This factor refers  
to the limit for the leakage indicator. Factory setting for factor 1 is 1.0.  
That means, for C1.LIMIT = 30.0 and factor 1 = 1.0, the first leakage  
error message is triggered at a leakage indication of 30.0.  
Factor 2  
Input of the factor for the threshold 2 error message. This factor refers  
to the limit for the leakage indicator. Factory setting for factor 2 is 1.5.  
That means, for C1.LIMIT = 30.0 and factor 2 = 1.5, the second  
leakage error message is triggered at a leakage indication of 45.0.  
Factor 3  
Input of the factor for the threshold 3 error message. This factor refers  
to the limit for the leakage indicator. Factory setting for factor 3 is 2.0.  
That means, for C1.LIMIT = 30.0 and factor 3 = 2.0, the third leakage  
error message is triggered at a leakage indication of 60.0.

Operation  
d. STIC  
Slipstick effect  
This parameter is used to activate the function for the detection of a  
slipstick effect. The device tries to detect sudden changes of the valve  
position that indicate excess slipstick. If the device detects a slipstick,  
the filtered step is saved as slipstick value. When the valve moves  
normally again (without detection of a slipstick), the slipstick value is  
reduced slowly.  
Note that to avoid misinterpretations, for actuators with actuating times  
below 1 s, the positioner cannot distinguish reliably between a normal  
movement and a sudden change.  
d1.LIMIT  
Limit for the slipstick detection  
Sets the limit for a step caused by a slipstick effect. The limit can be  
set within the range of 0.0 to 100.0%. Factory setting for the limit is 1.0.  
d2.FACT1  
Factor 1  
Input of the factor for the threshold 1 error message. This factor refers  
to the limit for the slipstick detection. Factory setting for factor 1 is 2.0.  
That means, for d1.LIMIT = 1.0 and factor 1 = 2.0, the first slipstick  
error message is triggered when the current slipstick value has reached  
2.0.  
d3.FACT2  
d4.FACT3  
Factor 2  
Input of the factor for the threshold 2 error message. This factor refers

That means, for d1.LIMIT = 1.0 and factor 2 = 5.0, the second slipstick  
error message is triggered when the current slipstick value has reached  
5.0.  
Factor 3  
Input of the factor for the threshold 3 error message. This factor refers  
to the limit for the slipstick detection. Factory setting for factor 3 is 10.0.  
That means, for d1.LIMIT = 1.0 and factor 3 = 10.0, the third slipstick  
error message is triggered when the current slipstick value has reached  
10.0.

Threshold for the monitoring of the dead zone adaptation.  
This value (%) can be used for the automatic adaptation of the dead  
zone. If the dead zone exceeds the set value, the threshold 3 error  
message is triggered. The three-level error message is not imple-  
mented for dead zone monitoring.  
F. ZERO  
Zero point offset  
This function is for detecting when the lower stop has changed its value  
compared to the value during initialization by more than the set

If the positioner is in automatic mode, statistical information is  
generated as to how long a valve or a flap was operated in which  
section of the actuating range. For this purpose, the entire actuating  
range (0 to 100 %) is divided into 8 sections (actuating ranges). The  
positioner registers the current position continuously and increments  
the operating hours counter that is assigned to the relevant section  
(actuating range) every hour. This allows conclusions to be made about  
past operating conditions and is in particular for the assessment of the  
control characteristics of the control loop or of the entire control valve.  
The actuating range is divided as follows:

4.5.3 Online diagnosis  
While the positioner is in operation, some important values and  
parameters are monitored on a continuous basis. In “Configuration”  
mode, you can configure this monitoring in such a way that the fault  
message output is activated when a certain event occurs, such as e.g.  
when a limit is exceeded.  
Table 4-2, page 133, shows which events can activate the fault  
message output and the alarm outputs, how the parameters need to be  
set for this event to be monitored, when the fault messages disappears  
again and what the possible causes of the malfunction are.  
In automatic and manual mode, the display shows what triggered the  
fault message when the fault message output reacts. The two numbers  
at the bottom left indicate the relevant error code. If several triggers  
occur simultaneously, they are display in succession cyclically. The  
device status that also includes all fault messages, can be called using  
command #48 via HART.  
The parameters of the extended diagnostics allow error messages to  
be displayed in one, two or three levels. In addition to the fault  
message output, alarm outputs 1 and 2 are then used. For this  
purpose, para-  
meter 51.XDIAG needs to be set according to the following table:

Table 4-2  
Events that can activate the fault message output  
Explanations for the “Error codes” column:  
1
Control deviation monitoring  
In automatic mode, the deviation between the setpoint and actual value  
is monitored continuously. According to the setting of parameter  
48. TIM, the monitoring time for setting the fault messages, and  
49. LIM, the response threshold of the fault message, the fault  
message is activated if the control deviation remains. As soon as the  
control deviation falls below the response threshold again, the fault  
message is cancelled.  
2
3
Automatic mode monitoring  
If parameter “47. FCT”, the fault message output function, is set  
accordingly, a fault message is generated if the device is not in  
automatic mode. In this way, e.g. the control system can be warned if  
the device was switched to manual mode or configuration on location.  
Binary input BE1 or BE2 active  
If parameter “47. FCT”, the fault message output function, and  
parameter “42.BIN1”, the binary input 1 function, are set accordingly,  
a fault message is generated when the binary input is activated. This  
can be e.g. a stuffing box monitoring switch, a temperature switch or a  
limit switch (e.g. for pressure).  
Binary input 2 (for the alarm unit option) can be configured in the same  
way.

Operation

Stroke number monitoring  
Monitoring of the number of changes of direction  
The two values, number of strokes and number of changes of direction,  
are compared to the threshold values on a continuous basis. These  
values result from the parameters “L1.LIMIT” to “L4.FACT3” and  
“O1.LIMIT” to “O4.FACT3”. If they are exceeded, depending on the  
operating mode of the extended diagnostics, the fault message output  
reacts, and possibly also the alarm outputs. The two functions can  
be deactivated by the parameter setting “OFF” for “L. STRK” or  
“O. DCHG”.  
6
7
Monitoring of the lower limit stop (valve seat)  
Monitoring of the upper limit stop  
The monitoring of the lower limit stop is activated if parameter  
“F. ZERO” has a value ¸OFF. This function can be used e.g.  
to detect valve seat errors. If the limit is exceeded, this can be an  
indication of deposits or foreign particles on the valve seat. If the limit is  
fallen short of, wear to the valve seat or reactor body could be the  
cause. The mechanical misadjustment of the position feedback can  
also trigger this error message.  
Monitoring takes place every time the valve is in “bottom tight closing”  
position. In doing so, the current position is compared to the position  
that was determined as lower end stop during the initialization phase.  
The activation of the “bottom tight closing function” (parameter  
“39.YCLS”) is therefore prerequisite.  
Example: 3% is set as value. For “bottom tight closing”, the 0% position  
is normally established. If a value of >3% or <--3% is determined  
instead, a fault is reported.  
The fault message remains activated until either a subsequent  
monitoring process remains within the tolerance range or a  
re-initialization is carried out. The deactivation of the monitoring  
process (“F. ZERO”=OFF) also deletes any fault messages.  
This monitoring function does not provide any useful results if the stops  
were not determined automatically during initialization but instead the  
limits were set by hand (manual initialization, “5.INITM”).  
An appropriate diagnosis was carried out for the upper limit stop. The  
parameter “G. OPEN” is used to set this limit. The activation of the  
“top tight closing function” (parameter “39.YCLS”) is therefore  
prerequisite.  
8
Dead zone adaptation monitoring  
If, during the automatic adaptation of the dead zone (parameter  
34.DEBA=Auto) the dead zone increases disproportionately during  
operation, this is an indication of a fault in the system (e.g. significantly  
increased stuffing box friction, play in the position displacement sensor,  
leakage). Therefore a limit can be specified for this value (“E1.LEVL3”,  
threshold for dead zone monitoring) that activates the fault message  
output if it is exceeded.

Partial stroke test exceeds reference step time  
This error message appears on the one hand if a manual or cyclic  
partial stroke test is triggered and the test cannot be started because  
the valve is not within the start tolerance range. The error message  
also appears if one of the three thresholds of the partial stroke test that  
are a result of the reference step time (A6.PSTIN) times factors  
(A7.FACT1 to A9.FACT3) is violated. How serious the error message  
is, can be seen at the bar graph on the right side of the display. At the  
same time, the severity of the error message is output via the fault  
message output or the alarm outputs, according to the operating mode  
of the extended diagnostics.  
10  
General control valve malfunction  
The monitoring of the operational behavior triggers if the actual valve  
position leaves a narrow corridor between guide value and expected  
position sequence. In this case, the deviation between expected and  
actual position sequence is filtered and output and compared to the set  
thresholds that are the result of the limit (b2.LIMIT) times the factors  
(b3.FACT1 to b5.FACT3).  
11  
12  
Pneumatic leakage  
This error message appears if the leakage indicator exceeds the set  
thresholds. Note that the function can only take effect with its entire  
sensitivity if a ramp test is performed to set the leakage indicator after  
initialization (see Explanations on C1.LIMIT).  
Slipstick effect too high  
If the slipstick of the control valve is increased during operation of if an  
increasing number of slip jumps are detected, the relevant limits can be  
exceeded, resulting in an error message.  
13  
14  
15  
Temperature fallen short of  
This error message appears if the lower temperature limit thresholds  
are fallen short of.  
Temperature exceeded  
This error message appears if the upper temperature limit thresholds  
are exceeded.  
Monitoring of the position average  
If a position average is calculated when a comparison interval passes  
that deviates from the reference value by more than the set thresholds,  
this error message triggers.

Operation  
4.7 Optimizing the controller data  
The data for the control quality that was automatically determined  
during initialization is optimized for short compensation with low  
overshooting. In special cases (e.g. extremely small and therefore  
particularly fast actuators or for operation with boosters), you might  
want to modify this data specifically for faster compensation or a  
greater damping effect. The following six parameters are available for  
this purpose:  
13 Pulse length up  
14 Pulse length  
down  
This is for defining the smallest pulse lengths with which the actuator is  
to move for each actuating direction. The optimal value mainly depends  
on the volume of the actuator.  
Small values result in small actuating increments and frequent activa-  
tion of the actuator. Bear in mind that if the values are too small, there  
will be no movement. Large values are advantageous for large actuator  
volumes. Also bear in mind that large actuating increments for small  
actuators also result in large movements.  
17 Short step zone up  
18 Short step zone down  
The short step zone is the range of the control deviation between the  
fast step zone and the dead band in which the actuator is activated by  
pulses.  
In the case of small control deviations, small values already cause  
relatively high actuating speeds and can therefore result in over-  
shooting. Large values in particular reduce overshooting in the case of  
large changes in the nominal value and result in slow actuating speeds  
near the compensated status.  
34 Prediction up  
35 Prediction down  
This parameter has the same effect as a damping factor and is used to  
set the control dynamics.  
Small values cause fast compensation with overshooting. Large values  
cause slow compensation without overshooting.  
We recommend that you perform an automatic initialization first and only then adapt the  
parameter determined by the positioner to your own special requirements.  
TIP: To have a fixed reference value, it is helpful if you specify a fixed value for the dead zone  
(DEBA parameter) instead of “Auto” for the optimization of your particular controller.  
You select the parameters above from the diagnosis menu in the accustomed manner and  
activate the joint adjustment by pressing the increment or decrement button for 5 seconds.  
If you now adjust the relevant parameter, the new value is activated immediately. You can test  
the effects of the new values on the controller results immediately.  
When you quit the diagnosis menu, the parameter adjustment option is deactivated again.

Service and Maintenance  
5
The positioner is largely maintenance-free. The positioners are fitted  
with filters in the pneumatic connections as protection against coarse  
particles of dirt. If the pneumatic energy supply contains particles of  
dirt, the filters may clog and impair the function of the positioner. In this  
case the filters can be cleaned as follows.  
Positioner in metal housing and explosion proof version  
1. Switch off the pneumatic power supply and remove the pipes.  
2. Remove the metal filters carefully from the holes and clean  
(e.g. with compressed air).  
3. Insert the filters.  
4. Re-connect the pipes and supply pneumatic energy.  
Positioner in plastic housing  
Removal  
1. Switch off the pneumatic power supply and remove the pipes.  
2. Unscrew the cover  
3. Remove the three screws from the pneumatic connector strip.  
4. Remove the filters and O-rings behind the connector strip.  
5. Clean the filters (e.g. with compressed air).  
Installation  
6. First insert the filters in the recesses in the plastic housing and then  
place the O-rings on the filters.  
7. Align the pneumatic connector strip on the two lugs and screw tight  
with the three self--tapping screws.  
Important:  
Make sure that the same thread is used. To do this turn the screws  
counterclockwise until they snap into the thread audibly. Only then  
should you tighten the screws.

Care and Maintenance  
8. Replace the cover and screw it tight.  
9. Re-connect the pipes and supply pneumatic energy.  
DANGER  
!
Electrostatic charging must be prevented in hazardous areas. These  
could be caused by example when cleaning the positioner in plastic  
housing with a dry cloth.  
Repair/Upgrade  
Faulty equipment should be sent to the repair department with details  
of the fault and its origin. When ordering replacement equipment,

The positioner and its options modules are delivered as separate units  
and in different versions. Positioners and options modules for operation  
in hazardous areas and non-hazardous areas are available. These ver-  
sions are identified respectively by a special rating plate.  
WARNING  
!
In the combination of components it must be ensured that only positio-  
ners and options modules are combined which are approved for the  
respective area of application. This applies especially for safe  
operation of the positioner in areas in which the atmosphere is poten-  
tially explosive (zone 1 and 2). The instrument categories (2 and 3) of  
the instrument itself and those of its options must be observed.
