The meters can have up to four setpoint outputs, determined by the optional  
plug-in cards. The setpoint plug-in cards provide dual FORM-C relays (5A),  
quad FORM-A relays (3A) or either quad sinking or quad sourcing open  
collector logic outputs. The outputs can be assigned to the timer, counter, RTC  
date, and RTC time. The outputs can also be independently configured to suit a  
variety of control and alarm requirements.  
Plug-in cards can also provide serial communications. These include RS232,  
RS485, and Modbus. Display values, setpoint alarm values and setpoint states  
can be controlled through serial communications. With the RS232 or RS485  
communication card installed, it is possible to configure the meter using a  
Windows® based program. The meter configuration data can be saved to a file  
for later recall.  
Once the meters have been initially configured, the parameter list may be  
locked out from further modification entirely, or the setpoint, timer start/stop  
values, counter start/stop values, RTC time SET, and Display Intensity can be  
made accessible. This lockout is possible through a security code or user input.  
The meters have been specifically designed for harsh industrial environments.  
With a NEMA 4X/IP65 sealed bezel and extensive testing to meet CE  
requirements, the meter provides a tough yet reliable application solution.  
GENERAL DESCRIPTION  
The PTC900 (Timer) and PTC901 (Clock/Timer) offer many features and  
performance capabilities to suit a wide range of industrial applications. Both can  
function as an Elapsed Timer or Preset Timer, while the PTC901 also offers  
Real-Time Clock with Date capability. The Plug-in option cards allow the  
opportunity to configure the meter for the present application, while providing  
easy upgrades for future needs.  
Both units can function as an Elapsed Time Indicator. By using two separate  
signal inputs and 23 selectable timer ranges, the meters can be programmed to  
meet most any timing application. With the addition of a Plug-in Setpoint card,  
they can easily become a dual or quad output preset timer.  
The PTC901 can also operate as a Real-Time Clock (RTC), with the Real-  
Time Clock Card already installed. The meter is capable of displaying time in  
12 or 24-hour time formats. The 12-hour format can be displayed in hours and  
minutes, with or without an AM/PM indication or in hours, minutes, and  
seconds. The 24-hour format can be displayed in hours and minutes or in hours,  
minutes, and seconds. The PTC901 is also capable of a calendar display in  
which the day, month and/or year can be displayed. The meter will recognize  
leap years, and can automatically adjust for Daylight Savings Time. The Real-  
Time Clock has the ability to externally synchronize with other PTC901 meters  
to provide a uniform display network throughout the plant.  
If the application calls for both a Preset Timer and a Real-Time Clock at the  
same time, the PTC901 can handle this requirement as well. The meter provides  
up to four different displays, accessed via front panel push buttons or external  
inputs. The displays are Timer (TMR), which displays the current timer value;  
Count (CNT), which displays the current cycle counter value; Date (DAT),  
which displays the current programmed date; and Real-Time Clock, which  
displays the current time. A battery-backed Real-Time Clock plug-in card is  
provided with the PTC901. This card, which includes a lithium coin-cell battery,  
will maintain the time and date when main power is removed.  
SAFETY SUMMARY  
All safety related regulations, local codes and instructions that appear in this  
literature or on equipment must be observed to ensure personal safety and to  
prevent damage to either the instrument or equipment connected to it. If  
equipment is used in a manner not specified by the manufacturer, the protection  
provided by the equipment may be impaired.  
Do not use this unit to directly command motors, valves, or other actuators  
not equipped with safeguards. To do so can be potentially harmful to persons or  
equipment in the event of a fault to the unit.  
The meters accept inputs from a variety of sources including switch contacts  
and outputs from CMOS or TTL circuits. The input can be configured to trigger  
on the edge or level of the incoming pulse. Internal jumpers are available to allow  
the selection for sinking inputs (active low) or sourcing inputs (active high).  
The front panel keys and three user inputs are programmable to perform  
various meter functions. One of the functions includes exchanging parameter  
lists, allowing for two separate listings of setpoint values, timer start/stop  
values, counter start/stop values and RTC daily on and off values.  
CAUTION: Risk of Danger.  
Read complete instructions prior to  
installation and operation of the unit.  
CAUTION: Risk of electric shock.  
Note: Recommended minimum clearance (behind the panel) for mounting  
clip installation is 2.1" (53.4) H x 5" (127) W.

1.0 INSTALLING THE METER  
Installation  
The meter meets NEMA 4X/IP65 requirements for indoor use when properly  
installed. The meter is intended to be mounted into an enclosed panel. Prepare  
the panel cutout to the dimensions shown. Remove the panel latch from the  
meter. Slide the panel gasket over the  
While holding the meter in place, push the panel latch over the rear of the  
meter so that the tabs of the panel latch engage in the slots on the case. The  
panel latch should be engaged in the farthest forward slot possible. To achieve  
a proper seal, tighten the latch screws evenly until the meter is snug in the panel  
(Torque to approximately 7 in-lbs [79N-cm]). Do not over-tighten the screws.

bezel. The meter should be  
installed fully assembled.  
Insert the meter into the  
Installation Environment  
The meter should be installed in a location that does not exceed the operating  
temperature and provides good air circulation. Placing the meter near devices  
that generate excessive heat should be avoided.  
panel cutout.  
The bezel should only be cleaned with a soft cloth and neutral soap product.  
Do NOT use solvents. Continuous exposure to direct sunlight may accelerate  
the aging process of the bezel.  
Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to operate the  
keypad of the meter.  
PANEL CUT-OUT  
2.0 SETTING THE JUMPERS  
To access the jumpers, remove the meter base from the meter case by firmly  
squeezing and pulling back on the side rear finger tabs. This should lower the  
latch below the case slot (which is located just in front of the finger tabs). It is  
recommended to release the latch on one side, then start the other side latch.  
Timer Input Logic Jumper  
One jumper is used for the logic state of both timer inputs. Select the proper  
position to match the input being used.  
User Input Logic Jumper  
One jumper is used for the logic state of all user inputs. If the user inputs are  
not used, it is not necessary to check or move this jumper.  
Warning: Exposed line voltage exists on the circuit boards. Remove  
all power to the meter and load circuits before accessing inside of  
the meter.

3.0 INSTALLING PLUG-IN CARDS  
The Plug-in cards are separately purchased optional cards that perform  
specific functions. These cards plug into the main circuit board of the meter. The  
Plug-in cards have many unique functions when used with the meters.  
To Install:  
1. With the case open, locate the Plug-in card connector for the card type to be  
installed. The types are keyed by position with different main circuit board  
connector locations. When installing the card, hold the meter by the rear  
terminals and not by the front display board.*  
CAUTION: The Plug-in card and main circuit board contain static  
sensitive components. Before handling the cards, discharge static  
charges from your body by touching a grounded bare metal  
object. Ideally, handle the cards at a static controlled clean  
workstation. Also, only handle the cards by the edges. Dirt, oil or  
other contaminants that may contact the cards can adversely  
affect circuit operation.  
2. Install the Plug-in card by aligning the card terminals with the slot bay in the  
rear cover. Be sure the connector is fully engaged and the tab on the Plug-in  
card rests in the alignment slot on the display board.  
3. Slide the meter base back into the case. Be sure the rear cover latches fully  
into the case.  
4. Apply the Plug-in card label to the bottom side of the meter. Do Not Cover  
the vents on the top surface of the meter. The surface of the case must be  
clean for the label to adhere properly. Apply the label to the area designated  
by the large case label.

for internal or external supply operation before continuing.  
4.0 WIRING THE METER  
b. Connect the shield to earth ground at both ends of the cable, usually when  
the noise source frequency is above 1 MHz.  
c. Connect the shield to common of the meter and leave the other end of the  
shield unconnected and insulated from earth ground.  
WIRING OVERVIEW  
Electrical connections are made via screw-clamp terminals located on the  
back of the meter. All conductors should conform to the meter’s voltage and  
current ratings. All cabling should conform to appropriate standards of good  
installation, local codes and regulations. It is recommended that the power  
supplied to the meter (DC or AC) be protected by a fuse or circuit breaker.  
When wiring the meter, compare the numbers embossed on the back of the  
meter case against those shown in wiring drawings for proper wire position.  
Strip the wire, leaving approximately 0.3" (7.5 mm) bare lead exposed (stranded  
wires should be tinned with solder.) Insert the lead under the correct screw-  
clamp terminal and tighten until the wire is secure. (Pull wire to verify  
tightness.) Each terminal can accept up to one #14 AWG (2.55 mm) wire, two  
#18 AWG (1.02 mm), or four #20 AWG (0.61 mm).  
3. Never run Signal or Control cables in the same conduit or raceway with AC  
power lines, conductors feeding motors, solenoids, SCR controls, and  
heaters, etc. The cables should be ran in metal conduit that is properly  
grounded. This is especially useful in applications where cable runs are long  
and portable two-way radios are used in close proximity or if the installation  
is near a commercial radio transmitter.  
4. Signal or Control cables within an enclosure should be routed as far as possible  
from contactors, control relays, transformers, and other noisy components.  
5. In extremely high EMI environments, the use of external EMI suppression  
devices, such as ferrite suppression cores, is effective. Install them on Signal  
and Control cables as close to the unit as possible. Loop the cable through the  
core several times or use multiple cores on each cable for additional protection.  
Install line filters on the power input cable to the unit to suppress power line  
interference. Install them near the power entry point of the enclosure. The  
following EMI suppression devices (or equivalent) are recommended:  
Ferrite Suppression Cores for signal and control cables:  
Fair-Rite # 0443167251  
EMC INSTALLATION GUIDELINES  
Although this meter is designed with a high degree of immunity to Electro-  
Magnetic Interference (EMI), proper installation and wiring methods must be  
followed to ensure compatibility in each application. The type of the electrical  
noise, source or coupling method into the meter may be different for various  
installations. The meter becomes more immune to EMI with fewer I/O  
connections. Cable length, routing, and shield termination are very important  
and can mean the difference between a successful or troublesome installation.  
Listed below are some EMC guidelines for successful installation in an  
industrial environment.  
TDK # ZCAT3035-1330A  
Steward # 28B2029-0A0  
Line Filters for input power cables:  
Schaffner # FN610-1/07  
1. The meter should be mounted in a metal enclosure, which is properly  
connected to protective earth.  
Schaffner # FN670-1.8/07  
Corcom # 1 VR3  
2. Use shielded (screened) cables for all Signal and Control inputs. The shield  
(screen) pigtail connection should be made as short as possible. The  
connection point for the shield depends somewhat upon the application.  
Listed below are the recommended methods of connecting the shield, in order  
of their effectiveness.  
Note: Reference manufacturers instructions when installing a line filter.  
6. Long cable runs are more susceptible to EMI pickup than short cable runs.  
Therefore, keep cable runs as short as possible.  
7. Switching of inductive loads produces high EMI. Use of snubbers across  
inductive loads suppresses EMI.  
a. Connect the shield only at the panel where the unit is mounted to earth  
ground (protective earth).

CAUTION: Timer Input common is NOT isolated from User Input common. In order to preserve the safety of the meter application, the timer input  
common must be suitably isolated from hazardous live earth referenced voltage; or input common must be at protective earth ground potential. If not,  
hazardous voltage may be present at the User Inputs and User Input Common terminals. Appropriate considerations must then be given to the potential  
of the User Input Common with respect to earth ground; and the common of the isolated plug-in cards with respect to input common.  
4.3 USER INPUT WIRING

(TXD) line and receives data on the Received Data (RXD) line. Data Computer  
Equipment (DCE) receives data on the TXD line and transmits data on the RXD  
line. The meter emulates a DTE. If the other device connected to the meter also  
emulates a DTE, the TXD and RXD lines must be interchanged for  
communications to take place. This is known as a null modem connection. Most  
printers emulate a DCE device while most computers emulate a DTE device.  
Some devices cannot accept more than two or three characters in succession  
without a pause in between. In these cases, the meter employs a busy function.  
As the meter begins to transmit data, the RXD line (RS232) is monitored to  
determine if the receiving device is “busy”. The receiving device asserts that it  
is busy by setting the RXD line to a space condition (logic 0). The meter then  
suspends transmission until the RXD line is released by the receiving device.

4.6 REAL-TIME CLOCK WIRING (PTC901)  
Time synchronization between multiple  
PTC901 meters can be accomplished through a  
hardware interface on the Real-Time Clock option  
card. This RS485 type interface allows connection  
of up to 32 PTC901 meters in a two-wire  
multidrop network, at distances up to 4000 ft.  
In a synchronization network, one PTC901  
meter is programmed as the Host, while all other  
meters are programmed as Slaves. Once every  
hour, the Host meter outputs  
a
time  
synchronization pulse onto the network. Upon  
receiving the synchronization pulse, each Slave  
meter automatically adjusts the minutes and  
seconds of its RTC Time setting to synchronize  
with the Host.

DISPLAY MODE  
module in sequence. Note that Modules 5 through 8 are only accessible when  
The meter normally operates in the Display Mode. In this mode, the meter  
displays can be viewed consecutively by pressing the DSP key. The  
annunciators to the left of the display indicate which display is currently shown;  
Timer (TMR), Cycle Counter (CNT), or Date (DAT). The Time Display for the  
Real-Time Clock is shown with no annunciator. Any of these displays can be  
locked from view through programming. (See Module 3.)  
the appropriate plug-in option card is installed. If lost or confused while  
programming, press the DSP key to exit programming mode and start over.  
When programming is complete, it is recommended to record the meter settings  
on the Parameter Value Chart and lock-out parameter programming with a User  
Input or lock-out code. (See Modules 2 and 3 for lock-out details.)  
PROGRAMMING MODE  
FACTORY SETTINGS  
Two programming modes are available.  
Factory Settings may be completely restored in Module 9. This is a good  
starting point if encountering programming problems. Throughout the module  
description sections which follow, the factory setting for each parameter is  
shown below the parameter display. In addition, all factory settings are listed on  
the Parameter Value Chart following the programming section.  
Full Programming Mode permits all parameters to be viewed and modified.  
Upon entering this mode, the front panel keys change to Programming Mode  
operations. This mode should not be entered while a process is running, since  
the meter timing functions and User Input response may not operate properly  
while in Full Programming Mode.  
Quick Programming Mode permits only certain parameters to be viewed and/or  
modified. When entering this mode, the front panel keys change to  
Programming Mode operations, and all meter functions continue to operate  
properly. Quick Programming Mode is configured in Module 3. The Display  
Intensity Level “ꢀꢄꢊꢅꢋ” parameter is only available in the Quick Programming  
Mode when the security code is non-zero. For a description, see Module 9—  
Factory Service Operations. Throughout this document, Programming Mode  
(without Quick in front) always refers to “Full” Programming Mode.  
ALTERNATING SELECTION DISPLAY  
In the module description sections which follow, the dual display with arrows  
appears for each programming parameter. This is used to illustrate the display  
alternating between the parameter (top display) and the parameter’s Factory  
Setting (bottom display). In most cases, selections or value ranges for the  
parameter will be listed on the right.

PROGRAMMING TIPS  
The Programming Menu is organized into nine modules. (See above.) These  
modules group together parameters that are related in function. It is  
recommended to begin programming with Module 1 and proceed through each  
ꢊꢅꢋꢅꢊ Selection/Value  
ª
Factory Settings are shown.  
STEP BY STEP PROGRAMMING INSTRUCTIONS:  
PROGRAMMING MODE ENTRY (PAR KEY)  
NUMERICAL VALUE ENTRY (ARROW, RST & PAR KEYS)  
For parameters which require a numerical value entry, the arrow keys can be  
used to increment or decrement the display to the desired value. When an arrow  
key is pressed and held, the display automatically scrolls up or scrolls down.  
The longer the key is held, the faster the display scrolls.  
The Programming Mode is entered by pressing the PAR key. If this mode is  
not accessible, then meter programming is locked by either a security code or a  
hardware lock. (See Modules 2 and 3 for programming lock-out details.)  
In addition, the RST key can be used in combination with the arrow keys to  
enter numerical values. The RST key is pressed to select a specific digit to be  
changed, which blinks when selected. Once a digit is selected, the arrow keys  
are used to increment or decrement that digit to the desired number. The RST  
key is then pressed again to select the next digit to be changed. This “select and  
set” sequence is repeated until each digit is displaying the proper number.  
Pressing the PAR key stores and activates the displayed value, and also  
advances the meter to the next parameter.  
MODULE ENTRY (ARROW & PAR KEYS)  
Upon entering the Programming Mode, the display alternates between ꢆꢁꢇ  
and the present module (initially ꢈꢉ). The arrow keys (F1S and F2T) are used  
to select the desired module, which is then entered by pressing the PAR key.  
PARAMETER (MODULE) MENU (PAR KEY)  
Each module has a separate parameter menu. These menus are shown at the  
start of each module description section which follows. The PAR key is pressed  
to advance to a particular parameter to be changed, without changing the  
programming of preceding parameters. After completing a module, the display  
will return to ꢆꢁꢇ ꢈꢉ. From this point, programming may continue by selecting  
and entering additional modules. (See MODULE ENTRY above.)  
PROGRAMMING MODE EXIT (DSP KEY or PAR KEY at ꢆꢁꢇ ꢈꢉ)  
The Programming Mode is exited by pressing the DSP key (from anywhere  
in the Programming Mode) or the PAR key (with ꢆꢁꢇ ꢈꢉ displayed). This will  
commit any stored parameter changes to memory and return the meter to the  
Display Mode. If a parameter was just changed, the PAR key should be pressed  
to store the change before pressing the DSP key. (If power loss occurs before  
returning to the Display Mode, verify recent parameter changes.)  
PARAMETER SELECTION ENTRY (ARROW & PAR KEYS)  
For each parameter, the display alternates between the parameter and the  
present selection or value for that parameter. For parameters which have a list of  
selections, the arrow keys (F1S and F2T) are used to sequence through the list  
until the desired selection is displayed. Pressing the PAR key stores and activates  
the displayed selection, and also advances the meter to the next parameter.

TIMER START VALUE  
This parameter determines how the Timer Input Signals affect the  
“Run/Stop” status of the Timer. The timing diagrams below reflect a Sinking  
input setup (active low). A Sourcing input setup (active high) is available  
through plug jumper selection (see Section 2.0). In this case, the logic levels of  
the timing diagrams would be inverted.  
The Timer can also be stopped using a Timer Stop Value or a Setpoint. This  
type of Stop condition is cleared when a Timer Reset occurs, or another start  
edge is applied.

The Timer returns to this value whenever a Timer Reset occurs. The value is  
entered in the same display format as the Timer Range selected. Non-zero  
values are normally used for “timing down” applications, but they can also  
provide an “offset” value when timing up.  
For ꢊꢅꢋꢅꢊ and ꢅꢀꢎꢅꢄꢏ operation, Input B provides a level active Timer  
Inhibit function. This function is also available through a User Input (see  
Module 2). Timing diagrams are shown below for “ꢊꢅꢋꢅꢊ” through “ꢐꢇꢊꢀꢄꢑ”  
modes. The “ꢊꢅꢋꢁꢂꢃ” through “ꢐꢁꢂꢃꢄꢑ” modes are identical except the  
timer display value is also reset at “Time Start” edges. In the “ꢐꢇꢊꢀꢄꢑ” and

6.2 MODULE 2 - USER INPUT AND FRONT PANEL FUNCTION KEY  
PARAMETERS (ꢑꢄꢚꢈꢡ)  
PARAMETER MENU  
Module 2 is the programming module for the rear terminal User Inputs and  
front panel Function Keys.  
PROGRAMMING MODE LOCK-OUT  
ꢝꢂꢅꢁꢄ«  
ꢆꢊꢉꢡ  
Three rear terminal User Inputs are individually programmable to perform  
specific meter control functions. While in the Display Mode, the function is  
ª
executed when the User Input transitions to the active state. Refer to the User  
Input specifications for active state response times. Certain User Input functions  
are disabled in “Full” Programming Mode. User Inputs should be programmed  
while in the inactive state.  
Three front panel Function Keys, F1, F2 and RST, are also individually  
programmable to perform specific meter control functions. While in the Display  
Mode, the primary function is executed when the key is pressed. Holding the  
F1 or F2 Function Keys for three seconds executes a secondary function. It is  
possible to program a secondary function without a primary function. The front  
panel key functions are disabled in both Programming Modes.  
Programming Mode is locked-out, as long as activated (maintained action).  
In Module 3, certain parameters can be setup where they are still accessible  
during Programming Mode Lock-out. A security code can be configured to  
allow complete programming access during User Input lock-out. This parameter  
does not apply to the function keys. Program only one user input for this function.  
EXCHANGE PARAMETER LISTS  
In most cases, if more than one User Input and/or Function Key is  
programmed for the same function, the maintained (level active) functions will  
be performed while at least one of those User Inputs or Function Keys are  
activated. The momentary (edge triggered) functions are performed every time  
any of those User Inputs or Function Keys transition to the active state.  
Some functions have a sublist of parameters, which appears when PAR is  
pressed at the listed function. A sublist provides yes/no selection for Display  
Values or Setpoints which pertain to the programmed function. The function  
will only be performed on the parameters entered as Z&4 in the sublist. If a User  
Input or Function Key is configured for a function with a sublist, then that  
sublist will need to be scrolled through each time, in order to access any  
parameters for the User Inputs or Function Keys which follow.

Two lists of parameter entries are available for the Timer/Counter Start and  
Stop Values; Setpoint On/Off and Time-Out Values; and Setpoint Daily On/Off  
Occurrence (for Real-Time Clock option). The two lists are named ꢊꢌꢂꢃꢄꢓ and  
ꢊꢌꢂꢃꢄꢢ. If a User Input is used to select the list, then ꢊꢌꢂꢃꢄꢓ is selected when  
the User Input is in the inactive state and ꢊꢌꢂꢃꢄꢢ is selected when the User  
Input is in the active state (maintained action). If a front panel Function Key is  
used to select the list, then the list will toggle for each key press (momentary  
action). The display will only indicate which list is active when the list is  
changed or when entering any Programming Mode.  
To program the values for ꢊꢌꢂꢃꢄꢓ and ꢊꢌꢂꢃꢄꢢ, first complete the  
programming of all the parameters. Exit programming and switch to the other

to access the “Full” Programming Mode. Access will only be allowed after  
entering a matching security code or the universal unlock code of ꢑꢑꢑ. With this  
lock-out, a User Input would not have to be used for the Program Lock-out  
function. Note however, the Security Code lock-out is overridden when an User  
Input, configured for Program Lock-out (ꢆꢊꢉꢡ), is not active (See Chart.)

PROGRAM LOCK-OUT PARAMETERS (VALUE ACCESS)  
“Full” Programming Mode permits all parameters to be viewed and  
modified. This programming mode can be locked with a Security Code and/or  
a User Input. When locked, and the PAR key is pressed, the meter enters a  
Quick Programming Mode. In this mode, access to Setpoint Values, Timer &  
Cycle Counter Start/Stop Values, and Time Setting for the Real-Time Clock can  
be programmed for “Read”, “Enter”, or “Lock” defined as follows:

This parameter selects the source from which a count is added to or

being used, which will exit the module and bypass the remaining parameters.  
When ꢝꢂꢅꢁꢄꢏ is selected, a count is generated each time the User 1 Input is  
activated. When selected as the count source, User Input 1 can still be  
programmed to perform a User Function described in Module 2, if desired. In  
this case, the Cycle Counter would be counting the number of times the  
particular User Function occurred.  
The Timer Reset (ꢃꢄꢁꢂꢃ) selection generates a count when either a manual  
or automatic reset occurs. (See Module 6 for programming Automatic Resets.)  
The Output ON/OFF selections generate a count when the chosen output  
either activates or deactivates. These selections only appear when a Setpoint  
Card is installed. O3 and O4 selections only appear for Quad Setpoint cards.

PREDEFINED TIMER OPERATING MODE  
The Predefined modes control the activation and deactivation of Output 1, in  
relation to Start and Reset signals applied to the Timer inputs. (See timing  
diagrams which follow.) When a selection other than ꢈꢉ is chosen, the  
parameters for Setpoint 1 (ꢂꢆꢄꢏ) in Module 6 are automatically configured to  
implement the selected operating mode. For some modes, parameters in  
Modules 1 and 2 are also automatically configured to properly implement the  
predefined mode. Refer to the chart shown with the timing diagrams for the  
specific parameters loaded for each predefined mode. Also, note the specific  
external wiring or plug jumper settings required for some modes.

This parameter is used to select Predefined Operating Modes for the Timer.  
These modes cover a variety of timing applications frequently encountered in  
industrial control processes. When using a Predefined mode, the operator needs  
only to set the actual Setpoint On/Off or Time-out values for the particular  
application. However, each programming parameter will still be accessible, in  
order to make modifications to the predefined settings if desired.  
The Setpoint On/Off or Time-out values for the specific application should  
be entered directly in Module 5 after selecting the operating mode. Only the  
value parameters which apply to the selected mode are displayed. These values  
can also be entered through Module 6, Setpoint (Alarm) Parameters, if desired.  
Select ꢈꢉ if not using a Predefined Operating Mode, in which case Setpoint  
parameters must all be individually programmed for the particular application.

Module 6 is the programming module for the Setpoint (Alarm) Output  
Parameters. This programming module can only be accessed if a Setpoint card  
is installed. Depending on the card installed, there will be two or four Setpoint  
outputs available. The Setpoint Assignment and Setpoint Action parameters  
determine the applicable Setpoint features, and dictate which subsequent  
parameters will appear for the Setpoint being programmed.

SETPOINT SELECT  
This parameter determines when the Setpoint output will activate. Output  
activation can occur at a specific Setpoint Value (ꢋꢓꢊꢝꢅ) or can be triggered by  
various “events”, as shown in the parameter list. Such events include the Timer  
starting (ꢃꢄꢂꢃꢁꢃ) or stopping (ꢃꢄꢂꢃꢉꢆ), or by the action (event) that causes  
another Setpoint output to turn On or Off. When programmed for an event, the  
Setpoint must not be used as the Setpoint On event for another Setpoint.  
Selecting ꢋꢓꢊꢝdisplays a sub-menu where the Setpoint value is entered. The  
Setpoint value is based on the meter display to which the Setpoint is assigned  
(ꢓꢂꢈꢄꢥ). When assigned to the Timer or Cycle Counter, the Setpoint value is  
entered in the same format as the assigned display. When assigned to the Real-  
Time Clock Date Display (ꢁꢃꢡꢄꢀ), the date value is entered in month.day.year  
format (ꢥꢥꢗꢀꢀꢗꢪꢪ). When assigned to the Real-Time Clock Time Display (ꢁꢃꢡꢄꢃ),  
the Setpoint value is always entered in ꢐꢐꢄꢈꢈꢆ format (Hours-Minutes with  
AM/PM selection). In Setpoint One-shot mode (See Daily On Occurrence), the  
One-shot Setpoint is enabled (armed) by scrolling the AM/PM digit until the 2nd  
digit decimal point is lit.

determines when the Setpoint output will deactivate. Output deactivation can  
occur at a specific Setpoint Off Value (ꢋꢓꢊꢝꢅ) or can be triggered by various  
“events”, as shown in the parameter list. Such events include the Timer starting  
(ꢃꢄꢂꢃꢁꢃ) or stopping (ꢃꢄꢂꢃꢉꢆ), or by the action (event) that causes another

If all days are set to ꢈꢉ, the Setpoint will operate in “One-shot” mode. When  
a One-shot setpoint is enabled (armed), the setpoint output will activate at the  
set time and disable itself from activating again. To enable or re-enable a one-  
shot alarm, go to the Setpoint value entry display and press the Up or Dn key  
repeatedly while the AM/PM digit is selected (flashing). When the 2nd digit  
decimal point is lit, the Setpoint is enabled. The Setpoint enable status is saved  
at power-down. The enable state of the Setpoint is not affected or changed when  
the Parameter List is exchanged.  
The setpoint will turn off (de-activate) as programmed per the Setpoint  
Action selected. If ꢉꢈꢄꢉꢜꢜ mode is selected, program all the Daily Off days to  
ꢟꢅꢖ to have the Setpoint turn off at the next Daily Off Occurrence. The One-  
shot status can also be viewed or set from the Setpoint Off value entry display.

This parameter only appears when the Data Bits parameter is set to a 7-bit  
data word length. Set the parity bit to match that of the other serial  
communications equipment on the serial link. The meter ignores parity when  
receiving data and sets the parity bit for outgoing data. If parity is set to ꢈꢉ, an  
additional stop bit is used to force the frame size to 10 bits.  
Selecting ꢪꢅꢂ displays a sublist for choosing the meter parameters to appear

decimal point and conforms the number to the scaled resolution. (ie. The meter’s  
scaled decimal point position is set for 0.0 and 25 is written to a register. The value  
of the register is now 2.5. In this case, write a value of 250 to equal 25.0).

procedure details construction of a command string:  
Day - 1 = Sunday through 7 = Saturday  
EX: 3 = Tuesday  
1. The first characters consist of the Node Address Specifier (N) followed by a  
1 or 2 character address number. The address number of the meter is  
programmable. If the node address is 0, this command and the node address  
itself may be omitted. The address suffix , “?” is the global broadcast address  
specifier. A command string that is sent with N? prefix will be accepted by  
all PAXCKs on the RS485 network (software code version 2.3 or greater).  
This is useful for setting all meters to the current time, date or day that may  
have unique meter addresses on a bus. It is important not to send (P)rint or  
(T)ransmit commands using N? prefix, as it will result in multiple meters  
responding at the same time. This is the only command that may be used in  
conjunction with other commands.  
Notes:  
1. Since the meter does not issue a reply to value change commands, follow  
with a transmit value command for readback verification.  
2. The date and day must be set separately.  
Transmitting Data From the Meter  
Data is transmitted from the meter in response to either a transmit command  
(T), a print block command (P) or User Function print request. The response  
from the meter is either a full field transmission or an abbreviated transmission.  
The meter response is established in Module 7.  
2. After the optional address specifier, the next character is the command  
character.

3. The next character is the Register ID. This identifies the register that the  
command affects. The P command does not require a Register ID character.  
It prints according to the selections made in print the options. If constructing  
a value change command (writing data), the numeric data is sent next.  
4. All command strings must be terminated with the string termination  
characters * or $. The meter does not begin processing the command string  
until this character is received. See Timing Diagram figure for differences  
between terminating characters.

This register sets the controlling mode for the outputs. In Auto Mode (0) the  
meter controls the setpoint output. In Manual Mode (1) the outputs are defined  
by the registers SOR. When transferring from auto mode to manual mode, the  
meter holds the last output value (until the register is changed by a write). Each  
output may be independently changed to auto or manual. In a write command  
string (VU), any character besides 0 or 1 in a field will not change the  
corresponding output mode.

These characters only appear in the last line of a block print.  
The abbreviated response suppresses the address and register mnemonics,  
leaving only the numeric part of the response.  
Note: Transmissions are formatted to match the way the parameter is displayed.  
This includes setpoints.  
Example: VU0011 places SP3 and SP4 in manual.  
Example: SP1 assigned to RTC. RTC format = 12:00 P.  
SP1 printout = 12:00 P.  
Setpoint Output Register (SOR) ID: X  
This register is used to view or change the states of the setpoint outputs.  
Reading from this register (TX) will show the present state of all the setpoint  
outputs. A “0” in the setpoint location means the output is inactive and a “1”  
means the output is active. The output logic parameter in Module 6 will affect  
the active logic state.  
Meter Response Examples:  
1. Address = 17, full field response, Cycle Counter = 875

In Automatic Mode, the meter controls the setpoint output state. In Manual  
Mode, writing to this register (VX) will change the output state. Sending any  
character besides 0 or 1 in a field or if the corresponding output was not first in  
manual mode, the corresponding output value will not change.  
Example: VX10* will result in output 1 active and output 2 inactive.  
COMMAND RESPONSE TIME  
SERIAL TIMING  
The meter can only receive data or transmit data at any one time (half-duplex  
operation). During RS232 transmissions, the meter ignores commands while  
transmitting data, but instead uses RXD as a busy signal. When sending  
commands and data to the meter, a delay must be imposed before sending  
another command. This allows enough time for the meter to process the  
command and prepare for the next command.

Transmit  
Refer to the Timing Diagrams below. At the start of the time interval t1, the  
computer program prints or writes the string to the com port, thus initiating a  
transmission. During t1, the command characters are under transmission and at  
the end of this period, the command terminating character (*, $) is received by  
the meter. The time duration of t1 is dependent on the number of characters and  
baud rate of the channel.  
P
Print  
Timing Diagrams  
NO REPLY FROM METER  
t1 = (10 times the # of characters) / baud rate  
At the start of time interval t2, the meter starts the interpretation of the  
command and when complete, performs the command function. This time  
interval t2 varies. If no response from the meter is expected, the meter is ready  
to accept another command.  
If the meter is to reply with data, the time interval t2 is controlled by the use  
of the command terminating character. The '*' terminating character results in a  
response time window of 50 msec. minimum and 100 msec. maximum. This  
allows sufficient time for the release of the sending driver on the RS485 bus.  
Terminating the command line with '$' results in a response time window (t2) of  
2 msec. minimum and 50 msec. maximum. The faster response time of this  
terminating character requires that sending drivers release within 2 msec. after  
the terminating character is received.  
RESPONSE FROM METER  
At the beginning of time interval t3, the meter responds with the first  
character of the reply. As with t1, the time duration of t3 is dependent on the  
number of characters and baud rate of the channel. At the end of t3, the meter is  
ready to receive the next command.  
t3 = (10 times the # of characters) / baud rate  
23  
COMMUNICATION FORMAT  
Data is transferred from the meter through a serial communication channel.  
In serial communications, the voltage is switched between a high and low level  
at a predetermined rate (baud rate) using ASCII encoding. The receiving device  
reads the voltage levels at the same intervals and then translates the switched  
levels back to a character.  
Start Bit and Data Bits  
Data transmission always begins with the start bit. The start bit signals the  
receiving device to prepare for reception of data. One bit period later, the least  
significant bit of the ASCII encoded character is transmitted, followed by the  
remaining data bits. The receiving device then reads each bit position as they  
are transmitted.  
The voltage level conventions depend on the interface standard. The table  
lists the voltage levels for each standard.  
Parity Bit  
LOGIC  
INTERFACE STATE  
mark (idle)  
RS232*  
RS485*  
After the data bits, the parity bit is sent. The transmitter sets the parity bit to  
a zero or a one, so that the total number of ones contained in the transmission  
(including the parity bit) is either even or odd. This bit is used by the receiver  
to detect errors that may occur to an odd number of bits in the transmission.  
However, a single parity bit cannot detect errors that may occur to an even  
number of bits. Given this limitation, the parity bit is often ignored by the  
receiving device. The meter ignores the parity bit of incoming data and sets the  
parity bit to odd, even or none (mark parity) for outgoing data.

* Voltage levels at the Receiver  
Data is transmitted one byte at a time with a variable idle period between  
characters. Each ASCII character is “framed” with a beginning start bit, an  
optional parity bit and one or more ending stop bits. The data format and baud  
rate must match that of other equipment in order for communication to take  
place. The figures list the data formats employed by the meter.  
Stop Bit  
The last character transmitted is the stop bit. The stop bit provides a single bit  
period pause to allow the receiver to prepare to re-synchronize to the start of a  
new transmission (start bit of next byte). The receiver then continuously looks  
for the occurrence of the start bit. If 7 data bits and no parity is selected, then 2  
stop bits are sent from the meter.

Time synchronization between multiple PTC901 meters can be  
accomplished through a hardware interface on the Real-Time Clock option  
card. This RS485 type interface allows connection of up to 32 PTC901 meters  
in a two-wire multidrop network, at distances up to 4000 ft. (See Section 4.6,  
Real-Time Clock Wiring).  
In a Synchronization network, one PTC901 meter is programmed as the Host  
(ꢐꢉꢂꢃ), while all other meters are programmed as Slaves (ꢂꢊꢓꢋꢅ). Once every  
hour (at 30 min. past the hour), the Host meter outputs a time synchronization  
pulse onto the network. Upon receiving the synchronization pulse, each Slave  
meter automatically adjusts the Minutes and Seconds of its RTC Time setting to  
synchronize with the Host. Synchronization, using the Real-Time Clock Wiring,  
adjusts the Minutes and Seconds only, and does not change the Hours, AM/PM,  
Day or Date settings in the Slave meter's RTC.

Full-time synchronization (hours, minutes and seconds) is possible for  
PAXCKs that are connected in an RS485 network (RS485 Serial Option cards  
required). In this configuration, one meter is designated as the Serial RTC  
Master by setting the meter's address as 98 or 99 (see Serial Real-time Clock  
Addressing in Master Module 7). Every hour (at 30 min past the hour), the  
Serial RTC Master / Host will transmit the full time (Hours, minutes, seconds)  
to all meters through the RS485 serial card wiring network. The time, date, or  
day will also be transmitted and updated in the Slaves when changed in the  
programming of the Serial RTC Master. Only one meter should be configured  
as Master and that meter should also be configured as the Host.

* NOTE: DO NOT ADJUST TRIM CAP ON RTC CARD!  
The Real-Time Clock circuit uses a crystal controlled oscillator for high  
accuracy timekeeping. The oscillator is factory calibrated* and optimized for  
25°C ambient temperature operation. Since the PTC901 is designed to operate  
over a wide temperature range, and since the accuracy of a crystal oscillator  
varies with ambient temperature, some drift in the RTC time may be observed  
over an extended period. This is primarily seen in high or low temperature  
installations. To compensate for the wide operating temperature range, a  
calibration or “Offset” value can be entered, which effectively slows down or  
speeds up the clock to maintain accurate timekeeping.

PTC901 Application  
A big application request has always been for  
Real-Time Clocks to display time throughout the  
plant. The challenge has been to keep all the  
various clock locations synchronized with the  
right time. With the new PTC901 Timer/Real-  
Time Clock this problem is history. You can install  
up to a maximum of 32 units. Simply select one of  
the units in the system as the host and the balance  
are programmed as slaves. The host will send out  
a synchronization pulse every hour to correct the  
time on any clock unit wired in the system.
