MOUNTING REQUIREMENTS  
Select a mounting location where there is  
minimum vibration and the ambient temperature  
range between 0 and 50 °C.  
The instrument can be mounted on a panel up to  
15 mm thick with a square cutout of 45 x 45 mm.  
For outline and cutout dimensions refer to Fig. 2.  
The surface texture of the panel must be better  
than 6,3 mm.  
The instrument is shipped with rubber panel  
gasket (50 to 60 Sh).  
To assure the IP65 and NEMA 4 protection, insert  
the panel gasket between the instrument and the  
panel as shown in fig. 1.  
While holding the instrument against the panel  
proceed as follows:  
Screw  
1) insert the gasket in the instrument case;  
2) insert the instrument in the panel cutout;  
3) pushing the instrument against the panel,  
insert the mounting bracket;  
bracket  
Panel  
4) with a screwdriver, turn the screws with a  
torque between 0.3 and 0.4 Nm.

CONNECTION DIAGRAMS  
NOTE: Any external components (like zener  
barriers etc.) connected between sensor and  
input terminals may cause errors in measurement  
due to excessive and/or not balanced line  
resistance or possible leakage currents.  
Connections are to be made with the instrument  
housing installed in its proper location.

NOTES:  
1) Before connecting the instrument to the power  
line, make sure that line voltage corresponds to  
the description on the identification label.  
2) To avoid electrical shock, connect power line at  
the end of the wiring procedure.  
3) For supply connections use No 16 AWG or larger  
wires rated for at last 75 °C.  
4) Use copper conductors only.  
5) Dont run input wires together with power cables.

OPEN INPUT CIRCUIT  
This instrument is able to identify the open circuit  
for TC and RTD inputs.  
The open input circuit condition for RTD input is  
shown by an "overrange" indication.  
For TC input, it is possible to select overrange  
indication (standard) or underrange indication set-  
ting the CH101 and SH101 according to the follow-  
ing table:  
PRELIMINARY HARDWARE  
SETTINGS  
1) Remove the instrument from its case.  
2) It is necessary to set J106 according to the  
desired input type as shown in the following figure.

DIRECT ACCESS TO SET POINT  
The transfer from AUTO to MANUAL and  
viceversa is bumpless (this function is not  
provided if integral action is excluded).  
If transfer from AUTO to MANUAL is performed  
during the first part of SMART algorithm (TUNE)  
when returning in AUTO the device will be forced  
automatically in the second part of the SMART  
algorithm (ADAPTIVE).  
At power up the device will be in the AUTO mode  
or as it was left prior to power shut down  
depending on P35 configuration selection.  
NOTE:When start up occurs in Manual mode with  
power output set to 0, the control outputs will be  
in accordance with the following formula: "rEV"  
output - "dir" output = 0  
When the device is in AUTO mode and in Normal  
Display Mode, it is possible to access directly to  
set point modification (SP or SP2).  
Pushing s or t for more than 2 s, the set point  
will begin changing.  
The new set point value becomes operative since  
no pushbutton has been depressed at the end of  
2 s timeout.  
MANUAL FUNCTION  
The MANUAL function can be accessed (only if  
enabled by P34=On) by depressing the MAN  
pushbutton for more than 1 sec.  
The command is accepted and executed only if  
the display is in "Normal Display Mode".  
When in MANUAL mode the LED's MAN  
annunciator will light up while the lower display  
shows the power output values.  
The value of "rEV" is shown in the two most signifi-  
cant digit field while the value of "dir" (if present) is  
shown in the two less significant digit field.  
The decimal point between the two values will be  
flashing to indicate instrument in manual mode.  
NOTE :  
LAMP TEST  
When it is desired to verify the display efficiency,  
push FUNC pushbutton for more than 10 s. The  
instrument will turn ON, with a 50 % duty cycle,  
all the LEDs of the display (we define this function  
"LAMP TEST").  
No time out is applied to the LAMP TEST.  
When it is desired to come back to the normal  
display mode, push FUNC pushbutton again.  
During the LAMP TEST the instrument continues  
to control the process but no keyboard functions  
are available (exception made for the FUNC  
pushbutton).

SERIAL LINK  
The device can be connected to a host computer  
by a serial link.  
SMART function  
It is used to optimize automatically the control  
action.  
The host can put the device in LOCAL (functions  
and parameters are controlled via keyboard) or in  
REMOTE (functions and parameters are  
controlled via serial link).  
To enable the SMART function, push the FUNC  
pushbutton until "Snrt" parameter is shown.  
Pushing s or t set the display "On" and push  
the FUNC pushbutton.  
The REMOTE status is signalled by the decimal  
point (labelled REM) at the right hand of the LSD  
of the upper display.  
This instrument allows to modify the operative  
and configuration parameters, via serial link.  
The necessary conditions to implement this  
function are the following:  
1) Serial parameters from SEr1 to SEr4 should be  
properly configured using the standard front  
keyboard procedure  
The SMRT LED will turn on or flashing according  
to the algorithm selected.  
When the smart function is enabled, it is possible to  
display but not to modify the control parameters.  
To disable the SMART function, push the FUNC  
pushbutton again until "Snrt" parameter is shown.  
Pushing s or t set the display "OFF" and  
push the FUNC pushbutton.  
The SMRT LED will turn off.  
2) Device must be in the OPERATING mode

parameters and it enables parameter modifica-

When P37 is different from zero and an out of  
range condition is detected, the instrument  
operates in accordance with P37 and P38  
parameters.  
ERROR MESSAGES  
OVERRANGE, UNDERRANGE AND  
SENSOR LEADS BREAK INDICATIONS  
The device is capable to detect a fault on the  
process variable (OVERRANGE or  
UNDERRANGE or SENSOR LEADS BREAK).  
When the process variable exceeds the span  
limits established by configuration parameter P 1  
an OVERRANGE condition will be shown on  
display as show in the following figure:  
NOTE: in every cases, the P18 and P20  
parameters will conditioned the real outputs of the  
instrument.  
The sensor leads break can be signalled as:  
- for TC/mV input : OVERRANGE or  
UNDERRANGE selected by  
a solder jumper  
- for RTD input  
- for mA/V input  
:
:
OVERRANGE  
UNDERRANGE  
NOTE : For mA/V input the leads break can be  
detected only when the range selected has a zero  
elevation (4/20 mA or 1/5 V or 2/10 V)  
For RTD input a special test is provided to signal  
OVERRANGE when input resistance is less than  
15 ohm (Short circuit sensor detection).  
An UNDERRANGE condition will be shown on  
display as show in the following figure:  
ERROR MESSAGES  
The instrument performs same self-diagnostic  
algorithm.  
When an error is detected, the instrument shows  
on the lower display the Errindication while the  
upper display shows the code of the detected  
error.  
When P37 is equal to 0, the following conditions  
may occur:  
- The instrument is set for one output only and if  
an OVERRANGE is detected, the output turns  
OFF (if reverse action) or ON (if direct action).  
- The instrument is set for heating/cooling action  
and an OVERRANGE is detected, "rEV" output  
turns OFF and "dir" output turns ON.  
- The instrument is set for one output only and if  
an UNDERRANGE is detected, the output turns  
ON (if reverse action) or OFF (if direct action).  
- The instrument is set for heating/cooling action  
and an UNDERRANGE is detected, "rEV"  
output turns ON and "dir" output turns OFF.
