GENERAL DESCRIPTION
The PAXTM (PAX Timer) and PAXCK (PAX Clock/Timer) offer many
features and performance capabilities to suit a wide ran e of industrial
applications. Both can function as an Elapsed Timer or Preset Timer, while the
PAXCK also offers Real-Time Clock with Date capability. The Plu -in option
cards allow the opportunity to confi ure the meter for the present application,
while providin easy up rades for future needs.
Both units can function as an Elapsed Time Indicator. By usin two separate
si nal inputs and 23 selectable timer ran es, the meters can be pro rammed to
meet most any timin application. With the addition of a Plu -in Setpoint card,
they can easily become a dual or quad output preset timer.
The PAXCK can also operate as a Real-Time Clock (RTC), with the Real-
Time Clock Card already installed. The meter is capable of displayin 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 PAXCK is also capable of a calendar display in
which the day, month and/or year can be displayed. The meter will reco nize
leap years, and can automatically adjust for Dayli ht Savin s Time. The Real-
Time Clock has the ability to externally synchronize with other PAXCK meters
to provide a uniform display network throu hout the plant.
If the application calls for both a Preset Timer and a Real-Time Clock at the
same time, the PAXCK 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 pro rammed date; and Real-Time Clock, which
displays the current time. A battery-backed Real-Time Clock plu -in card is
provided with the PAXCK. This card, which includes a lithium coin-cell battery,
will maintain the time and date when main power is removed.
The meters accept inputs from a variety of sources includin switch contacts
and outputs from CMOS or TTL circuits. The input can be confi ured to tri er
on the ed e or level of the incomin pulse. Internal jumpers are available to allow
the selection for sinkin inputs (active low) or sourcin inputs (active hi h).
The front panel keys and three user inputs are pro rammable to perform
various meter functions. One of the functions includes exchan in parameter
lists, allowin for two separate listin s of setpoint values, timer start/stop
values, counter start/stop values and RTC daily on and off values.
The meters can have up to four setpoint outputs, determined by the optional
plu -in cards. The setpoint plu -in cards provide dual FORM-C relays (5A),
quad FORM-A relays (3A) or either quad sinkin or quad sourcin open
collector lo ic outputs. The outputs can be assi ned to the timer, counter, RTC
date, and RTC time. The outputs can also be independently confi ured to suit a
variety of control and alarm requirements.
Plu -in cards can also provide serial communications. These include RS232,
RS485, Modbus, DeviceNet, and Profibus-DP. Display values, setpoint alarm
values and setpoint states can be controlled throu h serial communications.
With the RS232 or RS485 communication card installed, it is possible to
confi ure the meter usin a Windows®based pro ram. The meter confi uration
data can be saved to a file for later recall.
Once the meters have been initially confi ured, 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 throu h a security code or user input.
The meters have been specifically desi ned for harsh industrial environments.
With a NEMA 4X/IP65 sealed bezel and extensive testin to meet CE
requirements, the meter provides a tou h yet reliable application solution.

3.0 INSTALLING PLUG-INCARDS
The Plu -in cards are separately purchased optional cards that perform
specific functions. These cards plu into the main circuit board of the meter. The
Plu -in cards have many unique functions when used with the meters.
CAUTION: The Plu -in card and main circuit board contain static
sensitive components. Before handlin the cards, dischar e static
char es from your body by touchin a rounded bare metal
object. Ideally, handle the cards at a static controlled clean
workstation. Also, only handle the cards by the ed es. Dirt, oil or
other contaminants that may contact the cards can adversely
affect circuit operation.
To Install:
1. With the case open, locate the Plu -in card connector for the card type to be
installed. The types are keyed by position with different main circuit board
connector locations. When installin the card, hold the meter by the rear
terminals and not by the front display board.*
2. Install the Plu -in card by ali nin the card terminals with the slot bay in the
rear cover. Be sure the connector is fully en a ed and the tab on the Plu -in
card rests in the ali nment 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 Plu -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 desi nated
by the lar e case label.

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 volta e and
current ratin s. All cablin should conform to appropriate standards of ood
installation, local codes and re ulations. It is recommended that the power
supplied to the meter (DC or AC) be protected by a fuse or circuit breaker.
When wirin the meter, compare the numbers embossed on the back of the
meter case a ainst those shown in wirin drawin s for proper wire position.
Strip the wire, leavin 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 ti hten until the wire is secure. (Pull wire to verify
ti htness.) 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).
EMC INSTALLATION GUIDELINES
Althou h this meter is desi ned with a hi h de ree of immunity to Electro-
Ma netic Interference (EMI), proper installation and wirin methods must be
followed to ensure compatibility in each application. The type of the electrical
noise, source or couplin method into the meter may be different for various
installations. The meter becomes more immune to EMI with fewer I/O
connections. Cable len th, routin , and shield termination are very important
and can mean the difference between a successful or troublesome installation.
Listed below are some EMC uidelines for successful installation in an
industrial environment.
1. The meter should be mounted in a metal enclosure, which is properly
connected to protective earth.
2. Use shielded (screened) cables for all Si nal and Control inputs. The shield
(screen) pi tail 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 connectin the shield, in order
of their effectiveness.
a. Connect the shield only at the panel where the unit is mounted to earth
round (protective earth).
b. Connect the shield to earth round 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 round.
3. Never run Si nal or Control cables in the same conduit or raceway with AC
power lines, conductors feedin motors, solenoids, SCR controls, and
heaters, etc. The cables should be ran in metal conduit that is properly
rounded. This is especially useful in applications where cable runs are lon
and portable two-way radios are used in close proximity or if the installation
is near a commercial radio transmitter.
4. Si nal 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 hi h EMI environments, the use of external EMI suppression
devices, such as ferrite suppression cores, is effective. Install them on Si nal
and Control cables as close to the unit as possible. Loop the cable throu h 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
followin EMI suppression devices (or equivalent) are recommended:
Ferrite Suppression Cores for si nal and control cables:
Fair-Rite # 0443167251 (RLC# FCOR0000)
TDK # ZCAT3035-1330A
Steward # 28B2029-0A0
Line Filters for input power cables:
Schaffner # FN610-1/07 (RLC# LFIL0000)
Schaffner # FN670-1.8/07
Corcom # 1 VR3
Note: Reference manufacturer’s instructions when installing a line filter.
6. Lon cable runs are more susceptible to EMI pickup than short cable runs.
Therefore, keep cable runs as short as possible.
7. Switchin of inductive loads produces hi h EMI. Use of snubbers across
inductive loads suppresses EMI.
Snubber: RLC# SNUB0000.
4.0 WIRING THE METER

7
Before connectin the wires, the Timer Input lo ic jumper should be verified for proper position.
4.2 TIMER INPUT WIRING
CAUTION: Timer Input common is NOT isolated from ser 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 ser Inputs and ser Input Common terminals. Appropriate considerations must then be given to the potential
of the ser Input Common with respect to earth ground; and the common of the isolated plug-in cards with respect to input common.

4.5 SERIAL COMMUNICATION WIRING
RS232 Communi ations
RS232 is intended to allow two devices to communicate over distances up to
50 feet. Data Terminal Equipment (DTE) transmits data on the Transmitted Data
(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 PAX emulates a DTE. If the other device connected to the meter also
emulates a DTE, the TXD and RXD lines must be interchan ed 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 be ins to transmit data, the RXD line (RS232) is monitored to
determine if the receivin device is “busy”. The receivin device asserts that it
is busy by settin the RXD line to a space condition (lo ic 0). The meter then
suspends transmission until the RXD line is released by the receivin device.
RS485 Communi ations
The RS485 communication standard allows the connection of up to 32
devices on a sin le pair of wires, distances up to 4,000 ft. and data rates as hi h
as 10M baud (the PAX is limited to 19.2k baud). The same pair of wires is used
to both transmit and receive data. RS485 is therefore always half-duplex, that is,
data cannot be received and transmitted simultaneously.

Time synchronization between multiple
PAXCK meters can be accomplished throu h a
hardware interface on the Real-Time Clock option
card. This RS485 type interface allows connection
of up to 32 PAXCK meters in a two-wire
multidrop network, at distances up to 4000 ft.
In a synchronization network, one PAXCK
meter is pro rammed as the Host, while all other
meters are pro rammed as Slaves. Once every
hour, the Host meter outputs a time
synchronization pulse onto the network. Upon
receivin the synchronization pulse, each Slave
meter automatically adjusts the minutes and
seconds of its RTC Time settin to synchronize
with the Host. Real-Time Clo k Syn hronization Figure

PROGRAMMING MODE ENTRY (PAR KEY)
The Pro rammin Mode is entered by pressin the PAR key. If this mode is
not accessible, then meter pro rammin is locked by either a security code or a
hardware lock. (See Modules 2 and 3 for pro rammin lock-out details.)
MODULE ENTRY (ARROW & PAR KEYS)
Upon enterin the Pro rammin Mode, the display alternates between
and the present module (initially ). The arrow keys (F15and F26) are used
to select the desired module, which is then entered by pressin 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 chan ed, without chan in the
pro rammin of precedin parameters. After completin a module, the display
will return to . From this point, pro rammin may continue by selectin
and enterin additional modules. (See MODULE ENTRY above.)
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 (F15and F26) are used to sequence throu h the list
until the desired selection is displayed. Pressin the PAR key stores and activates
the displayed selection, and also advances the meter to the next parameter.
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 lon er the key is held, the faster the display scrolls.
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 di it to be
chan ed, which blinks when selected. Once a di it is selected, the arrow keys
are used to increment or decrement that di it to the desired number. The RST
key is then pressed a ain to select the next di it to be chan ed. This “select and
set” sequence is repeated until each di it is displayin the proper number.
Pressin the PAR key stores and activates the displayed value, and also
advances the meter to the next parameter.
PROGRAMMING MODE EXIT (DSP KEY or PAR KEY at )
The Pro rammin Mode is exited by pressin the DSP key (from anywhere
in the Pro rammin Mode) or the PAR key (with displayed). This will
commit any stored parameter chan es to memory and return the meter to the
Display Mode. If a parameter was just chan ed, the PAR key should be pressed
to store the chan e before pressin the DSP key. (If power loss occurs before
returnin to the Display Mode, verify recent parameter chan es.)
STEP BY STEP PROGRAMMING INSTRUCTIONS:
OVERVIEW
PROGRAMMING MENU
DISPLAY MODE
The meter normally operates in the Display Mode. In this mode, the meter
displays can be viewed consecutively by pressin 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 throu h pro rammin . (See Module 3.)
PROGRAMMING MODE
Two pro rammin modes are available.
Full Progra ing Mode permits all parameters to be viewed and modified.
Upon enterin this mode, the front panel keys chan e to Pro rammin Mode
operations. This mode should not be entered while a process is runnin , since
the meter timin functions and User Input response may not operate properly
while in Full Pro rammin Mode.
Quick Progra ing Mode permits only certain parameters to be viewed and/or
modified. When enterin this mode, the front panel keys chan e to
Pro rammin Mode operations, and all meter functions continue to operate
properly. Quick Pro rammin Mode is confi ured in Module 3. The Display
Intensity Level “” parameter is only available in the Quick Pro rammin
Mode when the security code is non-zero. For a description, see Module 9—
Factory Service Operations. Throu hout this document, Pro rammin Mode
(without Quick in front) always refers to “Full” Pro rammin Mode.
PROGRAMMING TIPS
The Pro rammin Menu is or anized into nine modules. (See above.) These
modules roup to ether parameters that are related in function. It is
recommended to be in pro rammin with Module 1 and proceed throu h each
module in sequence. Note that Modules 5 throu h 8 are only accessible when
the appropriate plu -in option card is installed. If lost or confused while
pro rammin , press the DSP key to exit pro rammin mode and start over.
When pro rammin is complete, it is recommended to record the meter settin s
on the Parameter Value Chart and lock-out parameter pro rammin with a User
Input or lock-out code. (See Modules 2 and 3 for lock-out details.)
FACTORY SETTINGS
Factory Settin s may be completely restored in Module 9. This is a ood
startin point if encounterin pro rammin problems. Throu hout the module
description sections which follow, the factory settin for each parameter is
shown below the parameter display. In addition, all factory settin s are listed on
the Parameter Value Chart followin the pro rammin section.
ALTERNATING SELECTION DISPLAY
In the module description sections which follow, the dual display with arrows
appears for each pro rammin parameter. This is used to illustrate the display
alternatin between the parameter (top display) and the parameter’s Factory
Settin (bottom display). In most cases, selections or value ran es for the
parameter will be listed on the ri ht.

This parameter determines how the Timer Input Si nals affect the
“Run/Stop” status of the Timer. The timin dia rams below reflect a Sinkin
input setup (active low). A Sourcin input setup (active hi h) is available
throu h plu jumper selection (see Section 2.0). In this case, the lo ic levels of
the timin dia rams would be inverted.
The Timer can also be stopped usin a Timer Stop Value or a Setpoint. This
type of Stop condition is cleared when a Timer Reset occurs, or another start
ed e is applied.
For and operation, Input B provides a level active Timer
Inhibit function. This function is also available throu h a User Input (see
Module 2). Timin dia rams are shown below for “” throu h “”
modes. The “” throu h “” modes are identical except the
timer display value is also reset at “Time Start” ed es. In the “” and

.2 MODULE 2 - USER INPUT AND FRONT PANEL FUNCTION KEY
PARAMETERS (#)
PARAMETER MENU
Module 2 is the pro rammin module for the rear terminal User Inputs and
front panel Function Keys.
Three rear terminal User Inputs are individually pro rammable to perform
specific meter control functions. While in the Display Mode, the function is
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” Pro rammin Mode. User Inputs should be pro rammed
while in the inactive state.
Three front panel Function Keys, F1, F2 and RST, are also individually
pro rammable to perform specific meter control functions. While in the Display
Mode, the primary function is executed when the key is pressed. Holdin the
F1 or F2 Function Keys for three seconds executes a secondary function. It is
possible to pro ram a secondary function without a primary function. The front
panel key functions are disabled in both Pro rammin Modes.
In most cases, if more than one User Input and/or Function Key is
pro rammed 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 (ed e tri ered) 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 pro rammed function. The function
will only be performed on the parameters entered as in the sublist. If a User
Input or Function Key is confi ured for a function with a sublist, then that
sublist will need to be scrolled throu h each time, in order to access any
parameters for the User Inputs or Function Keys which follow.

Display Mode, the CNT annunciator indicates the Cycle Counter display is
currently bein shown. An EXCHANGE PARAMETER LISTS feature, which
includes the Cycle Counter Start and Stop Values, is explained in Module 2.
This parameter selects the source from which a count is added to or
subtracted from the Cycle Counter. Select if the Cycle Counter is not
bein used, which will exit the module and bypass the remainin parameters.
When is selected, a count is enerated each time the User 1 Input is
activated. When selected as the count source, User Input 1 can still be
pro rammed to perform a User Function described in Module 2, if desired. In
this case, the Cycle Counter would be countin the number of times the
particular User Function occurred.
The Timer Reset () selection enerates a count when either a manual
or automatic reset occurs. (See Module 6 for pro rammin Automatic Resets.)
The Output ON/OFF selections enerate 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.

.5 MODULE 5 - TIMER OPERATING MODES ()
PARAMETER MENU
This module an only be a essed if a Setpoint Card is installed.
* Only the value parameters which apply t the selected m de will appear.
- Interval Timing (Edge Triggered)
- Interval Timing (Level Triggered)
- On-Delay/Interval Timing
- Repeat Cycle Timing
- Off-Delay Timing
- On-Delay Timing
This parameter is used to select Predefined Operatin Modes for the Timer.
These modes cover a variety of timin applications frequently encountered in
industrial control processes. When usin a Predefined mode, the operator needs
only to set the actual Setpoint On/Off or Time-out values for the particular
application. However, each pro rammin parameter will still be accessible, in
order to make modifications to the predefined settin s if desired.
PREDEFINED TIMER OPERATING MODE
ª
«
The Predefined modes control the activation and deactivation of Output 1, in
relation to Start and Reset si nals applied to the Timer inputs. (See timin
dia rams which follow.) When a selection other than is chosen, the
parameters for Setpoint 1 () in Module 6 are automatically confi ured to
implement the selected operatin mode. For some modes, parameters in
Modules 1 and 2 are also automatically confi ured to properly implement the
predefined mode. Refer to the chart shown with the timin dia rams for the
specific parameters loaded for each predefined mode. Also, note the specific
external wirin or plu jumper settin s required for some modes.
The Setpoint On/Off or Time-out values for the specific application should
be entered directly in Module 5 after selectin the operatin mode. Only the
value parameters which apply to the selected mode are displayed. These values
can also be entered throu h Module 6, Setpoint (Alarm) Parameters, if desired.
Select if not usin a Predefined Operatin Mode, in which case Setpoint
parameters must all be individually pro rammed for the particular application.
