GENERAL DESCRIPTION

The Apollo Intelligent RTD Meter (IMR) accepts standard RTD inputs and
precisely linearizes them into temperature readings. A full 6-digit display
accommodates a wide range of temperature inputs and holds large totalization
values. State-of-the-art digital circuitry virtually eliminates errors dueto drift. A full
complement of option packages is available to fulfill many process applications.

The indicator featuresa readout choice of eitherFahrenheit or Celsius with 0.1
or 1degree of resolution. English Style display prompts aid the operator through
set-up and operation. A front panel lock-out menu protects set-up data and
operation modes from unauthorized personnel. Programmable digital filtering
enhances the stabilityof the reading. Programmable remoteinput “E1-CON” pin
can be utilized to control a varietyof functions, such as totalizing,alarm control,
peak/valley reading, display hold or offset operations. All set-up data is stored in

2

E

PROM, which will hold data for a minimum of 10 years without power.

An optionalintegrator/totalizer can be used tototalize or integrate temperatures
up to a maximum display value of 999,999. It features independent scaling and a
low temperature cut-out to suit a wide variety of temperature integration
applications. Programmable remote input “E2-CON” pin is included with the
option and can be utilized to control a varietyof functions,such as totalizing, alarm
control, peak/valley readings, display hold or offset operations, simultaneously
with “E1-CON” pin. Peak/valley (max/min) reading memory functions are
included with this option and they are easily recalled and controlled by either the
front panel or a remote input. All readings are retained at power-down.

Optional dual relays with parallel solid state outputs are fully programmable
to operate ina wide variety of modes to suit many controlor alarm applications.

Optional 20 mA loop, bi-directional serial communications provides
computer and printer interfacingto extend the capabilities of the indicator.More
than one unit can be connected in the loop with other RLC products which have
serial communications capabilities.

An optional 4 to 20 mA or 0 to 10 VDC re-transmitted analog output can be
scaled by the user to interface with a host of recorders, indicators and controllers.
The type of analog output is determined by the Model No. that is ordered. (See
Ordering Information for available models.) The indicator has several built-in
diagnostic functions to alert operatorsof most malfunctions. Extensivetesting of
noise interference mechanisms and full burn-in make the indicator extremely
reliable in industrialenvironments. The die-castfront bezel meetsNEMA 4/IP65

requirements for washdown applications, when properly installed. Plug-in style
terminal blocks simplify installation wiring and change-outs.

THEORY OF OPERATION

The IMRemploys a microprocessor to perform the A/D conversion on the input
signal via a voltage-to-frequency converter. It digitally scales the result, corrects
for meter drift which maybe present and then displays the resultin a6-digit display
(4 digits for temperature, 6 digits for totalizer). The inputs are filtered to enhance
the stability of the display. A non-volatile E
permanent data retention for operating variables. The display consists of drivers
and 6-digit solid-state LEDs. The alarm option employs opto-isolators to isolate
the open collector devices from meter common. Operating in parallel, the relays
are type Form-C and arerated at5-amps. The serial communication option features
a built-in 20 mA current source and complete opto-isolation. The analog option
features a 12-bit DAC and provides an output signal that is digitally scaled. The
re-transmitted output is isolated from meter common.

PROGRAMMING AND OPERATING THE IMR

PROGRAMMING THE IMR

Although the unit has beenprogrammed at thefactory, the set-ups will generally
have to be changed to suit the application. Basic set-up is complete after units of
temperature selection, decimalpoint selection, and digitalfiltering level selection.

Before actually trying to program the indicator,it isadvised toorganize allthe
data for the programming steps to avoid any possible confusion and to read the
programming procedure entirely before proceeding.

To set-up the indicator, connect AC power and signal wires as outlined in the
connections section(Appendix “A”). Remove the jumperwire (if installed) from
TBA #3 (PGM. DIS.). This will allow the operator to enter and modify all of the
indicator’s parameters. Press the front panel button labeled “P”, momentarily.
Briefly, the display will show “Pro” alternately flashing with “0”.Thisisthe
indicator’s programming mode. The programming mode isdivided into sections,
numbered 0-9, each of which can be individually accessed. The front panel
“UP” and “DOWN” arrow buttons can be used to select one of these numbers
and the “P” button can be used to enter theselected programming module. In all
of theprogramming modules, “UP” and “DOWN” are used toeither select from
a list of choices or enter avalue. The “P” buttonisusedtosavethenewvalueand
progress to the next step within a module (Note: the new value takes effect when
“P” is pressed). Upon completion of a module, theindicator returns to the“Pro”
<>“0” stage. Pressing the “P” button at this time causes the unit to display
“End” after which the unit returns to the normal display mode. The following
table explains the basic function of each step.

Note: < > This indicates that the display will alternate between the English

prompt and the actual data.

-6-

DISPLAY RESULT OF “P” BUTTON

DISPLAY

RESULT OF “P” BUTTON

“Pro” < > “0” - Causes the indicator to return to normal display mode. Any

changes to set-updata arepermanently storedin the E

2

PROM.

“Pro” <>“1”- Entry into this module allows the user to select the RTD type,

whether the display will read in degrees Fahrenheit (F) or
Celsius (C), and display decimal point position.

“Pro” <>“2” - Entry into this module allows the user to select non-standard

display slope and display offset values. This enables the meter
to be “scaled” to a calibrated temperature probe. (This scaling

is NOT required for most applications.)

“Pro” <>“3”- Module #3 allows the user to program what can be accessed

from the front panel when the PGM. DIS. (Program Disable,
TBA #3) pin is connected to common. This feature protects
critical set-up data from accidentalmodification while allowing
access to setpoints and otherfunctions. The front panel lock-out
menu (quick programming) includes setpoint modification,
integrator/totalizer resetting, and peak/valley resetting.

Note: The term “Quick Programming” is used to refer to the
ability to change the information that can be accessed from the
front panel when the “PGM. DIS.” terminal is connected to
“COMM.”.

“Pro” <> “4” - Module #4 programs the digital filtering level and the function

of the remote input “E1-CON” pin (TBA #4), and if the totalizer
option isinstalled, theremote input“E2-CON” pin(TBA #8).The
functions of the remote E1 and E2 pins are the same and include
display hold, peak/valley modes, totalizer reset, alarm reset,
temperature offset, reading synchronization or print request.

“Pro” <>“5”- This module sets the time base,scale factor and low temperature

disable function for the optional integrator/ totalizer.

“Pro” < > “6” - This module allows programming forthe basic configuration of

the alarm option. The programming includes HI/LO acting,
tracking, alarm display, latched or auto-reset, assignment to
either the input or the integrator/totalizer, and alarm and
hysteresis values.

“Pro” <>“7” - Module #7 is the serial communication parameter programming.

Baud rate, unit address, print request function and condensed
prints are all programmable.

“Pro” <>“8”- This module allows digital scaling of the retransmitted analog

output. Display values that correspond to 4 mA or 0 VDC and
20 mA or 10 VDC arekeyed-in to scale the output and it may be
assigned to either the input or the integrator/ totalizer.

“Pro” <>“9”- This module is the service operation sequence and is not

normally accessed by the user. This step re-calibrates the basic
input and is used to compensate for long-term drift. Execution
of this module should be done by technicians with the proper
equipment in accordance with a maintenance plan of yearly
recalibrations. Acode numberentry step is used to protect from
inadvertent entries. Also, there is a number of other access
codes which provide test and set-up changes as an aid in
troubleshooting.

* Note: Thisfunction operates independent of the state ofthe “PGM. DIS.”pin.

-10-

MODULE #4 - PROGRAM DIGITAL FILTER AND REMOTE INPUT

PROGRAM DIGITAL FILTERING

If the displayed process signal is difficult to read due to small process
variations or noise, increased levels of filtering will help to stabilize the display.
This programming step may be used in conjunction with display rounding
programming(Pro1&2)to help minimize this effect. The digital filter used isan
“adaptive” filter. That is, the filter coefficients change dynamically according to
the nature of the input signal. This feature simultaneously allows the filter to
settle quickly for large inputchanges whileproviding a stable display reading for
normal process variations. Because of the adaptive nature of the filter, it cannot
be characterized in terms of a time constant. The following table lists the
maximum settling time for a step input to within 99% of final value.

“FILter” < > “0” - no digital filtering 1.5 sec.

Filter Value Settling Time (99%)

“1” - normal filtering 2 sec.
“2” - increased filtering 6 sec.
“3” - maximum filtering 13 sec.

PROGRAM FUNCTION OF E1-CON AND
OPTIONAL E2-CON PIN

The function of the remote input “E1-CON” pin (TBA #4) and, if the totalizer
option is installed, the remote input “E2-CON” pin (TBA #8) are the same.
Functions are activated, as described in the appropriate function, when
connected to signal common (TBA #7). Whether a function is edge or level
activated it must be held low for a minimum of 20 msec in order for the function
to occur. The remote input pins can be used simultaneously and with any
combination of functions. When pins are tied together and activated, E1-CON
function is generally performed first.

“E1-CON”< > “0” - If the Totalizer/Peak/Valley/Display Offset option is

installed, a negative going edge offsets the displayed
temperature to zero.(At the timethe E-Pin isactivated, the value

of the actual temperature being displayed is placed in the
location of the display offset value. To bring the unit into the
normal temperature display mode, reset the offset value to zero
via the front panel.)

“1” - A negative goingedge resets the contents ofthe totalizerto zero.

Totalization commences regardless of the state of the input.

“2” - A negative going edge resets the contents of the totalizer to

zero and allows totalization as long as input is low. If the input
goes high, totalization is stopped and the contents are saved.
This acts as a totalization enable control from time T1 to T2.

“3” - A low level allows totalization as long as the input is low. If the

input goes high, totalization isstopped and the contents aresaved.
This acts as a totalization enable control from time T1 to T2.

“4” - Alow level holdsthe display (display hold).While thisinput is

low, the indicator continues to process the input signal and
drive the alarms, totalizer, etc. with the actual signal. The
contents of the totalizer are stored at the same time the input
display is held.

Note: If display hold is activated, and input value is requested via

serial, the value onthe displaywill besent instead of the actual
input value at that time.

“5” - A negative going edge resets both peak and valley buffers.

Note: If P/V is called up, a change will not appear on the display

until the next time the P/V is called up.

“6” - A negative going edge resets only the peak buffer and the

indicator enters a peak reading display mode as long as the
input is low. If the input goes high, peak detection and
indication are stopped and the last peak reading is retained.

“7” - A negative going edge resets only the valley buffer and the

indicator enters a valley reading display mode as long as the
input is low. If the input goes high, valley detection and
indication are stopped and the last valley reading is retained.

“8” - If the alarmoption is installed, a negativegoing edgeresets the

latched alarm(s).

-11-

PROGRAM FUNCTION OF E1-CON AND
OPTIONAL E2-CON PIN (Cont’d)

“9” - If the alarm option is installed, a low level resets a latched or

unlatched alarm into its inactive state. This provides manual
override of alarms for systemstart-up and otherunusual events
such as system testing.

“10” - A negative going edge toggles the display between “input”

and “total” (from input to total, or vice versa). No action is
taken on the positive going edge.

“11” - A negative going edge zeros (tares) the input signal and adds

the value that was in the input display to the totalizer value,
every time this operation is performed. The time-base, scale
factor and low cut-out in “Module #5” are in affect disabled,

when this function is selected.

“12”- Displayhold with offset. A negative going edgetares (zeros) the

input signal. Prior to the offset operation, the input signal is saved
and held (display hold) as long as the remote input pin is low. On
the positive edge, the input display will show zero. If there is an
increase to the input signal while the remote input is low, the
display will reflect (show) the increase at the positive edge.

“13”- Instrument reading synchronization. A low level disables all

meter operations (alarms, total, analog out, etc.). A positive
edge resets the start of the A/D conversion, to allow
synchronization withexternal processes and controls. While in
this function, the other E-CON pin will be operational.

“14”- Print request. Transmits data according to the print options

that have been selected in Program Module #7. If the low time
exceeds 800 msec, a second print-out may occur.

“E2-CON” < > If the totalizer option is installed, E2-CON has the same

programmable functions as E1-CON.

-12-

MODULE #5 - PROGRAM INTEGRATOR/TOTALIZER

Programming for the integrator/totalizer consists of four programming steps:
totalizer decimal point position, time base, scale factor and low temperature
disable. Note that the decimal point position of the integrator/totalizercan be set
independent of the decimal point position of the input. The totalizer value will
roll over and flash when the total exceeds, 999999 or -99999, indicating an
overflow condition. Reverse signal inputwill cause the totalizervalue to count in
the opposite direction and eventually no longer be in an overflow condition.

PROGRAM DECIMAL POINT POSITION FOR THE
INTEGRATOR/TOTALIZER

The decimal point position for the totalizer are as follows:

“dECPNt”<>“0”

PROGRAM INTEGRATOR/TOTALIZER TIME BASE

The time base determines the rate at which readings increase. The
integrator/totalizer display is updated
base selected, butlonger time bases decrease themagnitude ofeach increase.The
three time bases are per second, per minute and per hour. A constant input
temperature of 100°, forexample, wouldintegrate/totalize to 100° in one second
(withaTBof1sec.), 100° in one minute (withaTBof1min.), and 100° in one
hour (withaTBof1hr.). (Note: Input changes can be made synchronous to the

display byprogramming E1or optional E2-CON pin for function 13, Instrument
reading synchronization.) A multiplying scale factor may be used to span the

standard time ranges (or divide if scale factor < 1). The following equation
expresses the integration/totalization process.

PROGRAM THE INTEGRATOR/TOTALIZER SCALE FACTOR

As explained in the previous programming step, a multiplyingscale factorcan
be used to scale the update rateas required.This may be used tospan thestandard
ranges. A scale factor of “1.000” has no effect on the standard ranges.

“SCLFAC” < > “0.001” to “100.000”

PROGRAM THE LOW-END CUTOUT (low temperature level
disable)

In order to prevent false integration/totalization in situations where
integration/totalization is undesirable, a programmable setpoint can be used to
disable integration/totalization when the input temperature falls below this
low-end cutout level.

“Lo-cut” < > “-999” to “9999”

-13-

MODULE #6 - PROGRAM ALARM/SETPOINT

If the alarm option is installed, this module is used to configure the operation of
the alarms to a variety of combinations. The programmable options are HI/LO
acting, auto/manual reset (latching), tracking, assignment to input or
integrator/totalizer, display alarms,alarm values and hysteresis (deadband)values.

ALARM TRACKING

With alarm tracking, whenever alarm#2 ischanged, alarm #1 will also change
so thatthe offset between alarm #2 and alarm#1 remainsthe same.This is useful
for hierarchical setpoints (pre-alarm and alarm) when one change applies to
both alarm values.When programmingfrom thefront panel, trackingonly occurs
when PGM. DIS. is low (front panel lock-out mode, alarm #1 will not appear).
Tracking will always occur if alarm #2 is modified via serial communications
independent of PGM. DIS.

DISPLAY ALARMS

If display alarms are desired, a message will flash on the display every 5-10
secs when an alarm activates. For alarm 1, themessage will flash “AL1 ON”and
alarm 2 will flash “AL2 ON”, this warns an operator of an alarm condition. The
message will stop when the unit is no longer in an alarm condition.

AUTO OR MANUAL RESET FOR ALARM #1

The reset action of alarm #1 may be programmed to reset automatically
(unlatched) or be programmed torequire amanual reset (latched), through either
a remote input (E1-CON or optional E2-CON) or through the front panel.
Latched alarms are usually used when an operator is required to take some action

Alarm #1 may be programmed to activate on either the input or the
integrator/totalizer value. If the integrator/totalizer option is not installed, this
step defaults to the input.

“ASN-1” < > “INPUt” or “totAL”

PROGRAM VALUE FOR ALARM #1

The range of the alarm value is -999 to 9,999 for the input display and -99999
to 999999 for the totalizer option display.

“AL-1” < > “-999” to “9999”

PROGRAM HYSTERESIS VALUE FOR ALARM #1

(Cannot be programmed if alarm latch is programmed)

The hysteresis (deadband) value for alarm #1 may be programmed from 1 to
9,999 for the input and 1 to 999999 for the totalizer option. The value is either
added to or subtracted from the alarm value depending on whether the alarm is
high or low acting. (See “alarm” section for operation.)

The action of alarm #1 may be programmed to activate either when the signal
goes above the alarm value (high acting) or goes below it (low acting).

“Act-1”<>“HI”or“LO”

AUTO OR MANUAL RESET FOR ALARM #2

The reset action of alarm #2 may be programmed to reset automatically
(unlatched) or be programmed torequire amanual reset (latched), through either
a remote input (E1-CON or optional E2-CON) or through the front panel.
Latched alarms are usually used when an operator is required to take some action
for the alarm condition.

Note: Depending on options selected under Pro 3 and Pro 6, alarms, hysteresis,

peak, and valley values can be monitoredand/or changed when PGM. DIS. is

tied to COMM. This provides a “QUICKPROGRAMMING” method for “day

to day” process changes. (See QUICK PROGRAMMING SECTION for more

details.)

MODULE #7 - PROGRAM SERIAL COMMUNICATIONS

Several programmable parameters must be programmed before serial
communication can occur.

BAUD RATE

Select one of the baud rates from the list to match the baud rate of the printer,
computer, controller, etc.

“bAud” < > “300” - 300 baud

“600” - 600 baud
“1200” - 1200 baud
“2400” - 2400 baud

UNIT ADDRESS NUMBER

To allow multiple units to communicate on the 20 mA loop, different address
numbers must be assignedto each unit. If only one unit is on the loop, an address
of “0” may be given, eliminating the need for the address command.

“AddrES” < > “0” to “99”

PRINT REQUEST FUNCTION

A selection of print operations can be programmed. A print operation occurs
when a print request is activated via E1-CON (TBA #4) or optional E2-CON
(TBA #8) pin, or a “P” command is sent from a terminal via the serial
communications option. If the option to which a particular print code applies is
not installed, then that parameter will not be printed.

If the totalizer is overflowed, an asterisk (*) will precede the digits that are
printed (ex. *000127 positive overflow, -*00127 negative overflow).Ifthe
temperature exceeds the range of the unit or the sensor opens, the print-out will
show “OPEN” and for the negative direction or shorted will show “SHOrt”.

“Print” < > “0” - input signal

“1” - input signal, peak, valley and offset
“2” - input signal and alarm 1 and alarm 2
“3” - input signal, alarm 1, alarm 2, hysteresis 1,

hysteresis 2, peak, valley, and offset
“4” - totalizer
“5” - input signal and totalizer
“6” - input signal, totalizer, peak, valley, and offset
“7” - totalizer and alarm 1, and alarm 2
“8” - input signal, totalizer, alarm 1, and alarm 2
“9” - input signal, totalizer, alarm 1, alarm 2,

hysteresis 1, hysteresis 2, peak, valley, and offset

FULL OR ABBREVIATED TRANSMISSION

When transmitting data, the IMR can be programmed to suppress the address
number, mnemonics and some spaces,if desired,by selecting“NO”. Aselection
of “NO” results in faster transmission. This feature may be helpful when
interfacing with a computer. When interfacing to a printer, a “yES” response is
usually desirable.

“FULL” < > “yES” or “NO”

An example of full and abbreviated transmission is shown below:

2 RTD -125.7F < CR > < LF > Full transmission

-125.7 < CR > < LF > Abbreviated transmission

-16-

MODULE #8 - PROGRAM RE-TRANSMITTED ANALOG OUTPUT

This programming module allows digital scaling of the 4 to 20 mA or 0 to 10
VDC analog output. The type of analog output is determined by the Model
ordered. (See Ordering Information for available models.) The display value at
which4mAor0VDCandthedisplayvalueatwhich20mAor10VDCare
transmitted are keyed-in. The indicator automatically calculates slope and
intercept values to complete the scaling. The analog output then follows the
calculated display value and as such will update every measurement cycle. The
output may also be programmed to proportionally re-transmit the contentsof the
totalizer instead of the input. Reverse acting output can be achieved by
programming the “high” display value for the “AN-LO” programming step and
the “low” display value for the “AN-HI” step.

Note: DO NOT ADJUST THE ANALOG OUTPUT POTS ON THE BACK OF

THE UNIT. Fine offset and span adjustment pots are externally accessible to

compensate for small drifts in the output. These pots have been set at the

factory and do not normally require adjustment.

ANALOG OUTPUT SOURCE

Program whether the input or the totalizerwill serveas the basis for the analog
output signal. If the integrator/totalizer option is not installed, then this step
defaults to “Input”.

ANALOG OUTPUT LO DISPLAY VALUE

Program the display value at which the analog output transmits 4 mA or 0
VDC.

ANALOG OUTPUT HI DISPLAY VALUE

Program the display value at which the analog output transmits 20 mA or 10
VDC.

“ASIN” < > “INPUt” or “totAL”

“AN-Lo” < > “-999” to “9999” for “INPUt”

“-99999” to “999999” for “totAL”

“AN-HI” < > “-999” to “9999” for “INPUt”

“-99999” to “999999” for “totAL”

-17-

MODULE #9 - SERVICE OPERATIONS

The indicator has been fully calibrated at the factory. If the unit appears to be
indicating incorrectlyor inaccurately, refer to the troubleshootingsection before
attempting this procedure.

When re-calibration is required (generally every 2 years), this procedure
should onlybe performedby qualified technicians using appropriate equipment.
Resistance source accuracies of 0.02% or better are required.

The procedure consists of applying accuratesignal levels to the indicator in a series
of two steps. Allow a 30 minute warm-up period before starting this procedure.

Note: Once the access code has been entered, there is no exiting the program

module without completing the calibration procedure.

ENTER ACCESS CODE

A code number (48) must be keyed-in prior to the calibration sequence to
guard againstinadvertent entries.Access codenumbers otherthan thoselisted in
this section should not be entered at this step. If any are entered, undefined or
unpredictable operation could result.

“CodE” < > “0” to “99”

If the code number forthe previous stepwas not recognized,the indicator returns
to “Pro 0”, with no action taken. Otherwise, the calibration procedure is started.

ENTER ZERO REFERENCE

Apply 0 ohms to input by shorting Terminals 5, 6, and 7 as
shown in the drawing to the right. Allow to stabilize for 20
seconds before pressing “P”.

“StEP 1” (Press “P”)

APPLY PRECISION RESISTANCE

Terminals 5 and 6 remain shorted. (Note: Be certain to short
Terminals 5 and 6 at the resistor as shown in the drawing to the
right. Shorting terminals may lead to incorrect calibration.)

Connect a precision 300W resistor across Terminals 6 and 7.

Allow to stabilize for 20 seconds before pressing “P”.

“StEP 2” (Press “P”)

Indicator calibration is complete. It is recommended that calibration be

checked by comparingthe displayed temperaturewith a precisionthermometer.

SERIAL HARDWARE (loop-back) DIAGNOSTICS

The internal serial
communications hardware
in the IMR can be tested to
verify proper operation. The
procedure consists of
connecting the Serial Input
(SI), Serial Output (SO),and
20 mA Source into a simple
loop, and then entering an
access code.

Connect the IMR as
shown at right. Enter “Pro
9”,key-in“Code 39”, and
then press “P”.Iftheserial
communication hardware is
OK, “PASS” will be
displayed.

Conversely, if there is an internal problem, “FAIL” will be displayed. After
the diagnostic test is complete, press “P” to return to “Pro 0”.

“CodE” < > “39”

RESTORING ALL PROGRAMMING PARAMETERS BACK TO
FACTORY CONFIGURATION

All of the programming in Modules #1 through #8 can be restored back to the
factory configuration by entering a specific access code (refer to the “Factory
Configuration” section for the data that willbe entered).The procedure consists of
entering “Pro 9”, keying-in “Code 66”, then pressing “P”.The IMR responds by
displaying “INItAL” for several seconds, and then returns to “Pro 0”.

Note: When this procedure is performed, all of the scaling, presets, etc. that
were programmed into the IMR will be overwritten.

“CodE” < > “66”

-18-

OPERATING THE IMR

After completing all set-up operations, the unit is ready to install and operate.
After power is applied, a display test consisting of illuminating all segments for 2
seconds is performed.Afterward, the inputor total willappear, dependingupon the
display mode prior to the last power-down. To switch the display to input, press

“DOWN” (indicated by“arrows” onthe front panel) andtoswitchittototal,press
“UP”. If the integrator/totalizer option is not installed, then display switching to
total is inoperative. A minus sign “-” will precede numbers that are negative.

QUICK PROGRAMMING

To limit access to the set-up parameters, connect a key-switch or wire from
PGM. DIS. (TBA #3) to COMM. (TBA #7). With this pin connected to common,
only a predetermined amount of data can be viewed or altered, as programmed by
programmingmodule #3. If “NO” was programmed for all of the available stepsin
module #3, then pressing “P” will cause the unit to display “Loc”. However, if
“YES” was programmed in one or more of the steps, then “P” will invoke entry
into a series of commonly modified parameters while protecting the crucial set-up
information. This is referred to as the “quick programming” mode. When “quick
programming” mode is entered, the alarms and hysteresis values can be modified
in the same manner as in the regular programming mode. The new alarm and
hysteresis values will take effect when “P” is pressed. The other operations in the
“quick programming” mode require special key sequences as shown:

To reset latched alarm, scrollthrough stepsin “quick programming”
mode using the “P” button until “LAtCH1” or “LAtCH2” appears
in the display. If they do not appear, they are not latched.

To reset: While “LAtCH1” or “LAtCH2” is being
displayed, press and hold “DOWN” and press “P”.
Pressing “P” alone causes a step to the nextitem with
no action on the alarm.

To reset peak and valley buffers, scroll through steps in “quick
programming” mode using the “P” button until “PEA” or “VAL”
appears in the display.

To reset: While “PEA” or “VAL”is being displayed,
press and hold “DOWN” and press “P”. Pressing
“P” alone causes a step to the next item with no
action taken on the buffer.

The front panel buttons are not only used to input data during the programming
and “quickprogramming” mode, but controla number of other functions (if enabled
in Pro “3”) as well. In the normal meter mode, these functions are available:

To switch to display of input: Press “DOWN” button.
To switch to display of totalizer: Press “UP” button.
To reset totalizer to zero: Press and hold “UP” and press “P”.
To enter programming or “quick programming”:Press“P”.

After each operation,a message willappear briefly toacknowledge the action.

TEMPERATURE MONITORING EXAMPLE

An IMR is installed as a monitoring device and back-up controller
for a freezer storage facility. Normally, the freezer temperature is
maintained at about -29°C ±2°. The absolute maximum allowable
temperature of thefreezer is 0°C.In theevent of a systemfailure, alarm
output #1 of the IMR is programmed to start a secondary cooling
system should the temperature reach 0°C. The additional alarm of the
IMR is used to signal personnel with a warning bell when the
temperature rises above -17°C (indicating a possible failure of the
main cooling system). This alarm is programmed to latch in order to
assure that personnel inform maintenance of a possible problem. Key
switches are installed to lock out the front panel from unauthorized
personnel and to provide the means to reset the latched alarm. The
Integrator/totalizer option is specified to store peak and valley
temperatures overnight, weekly, etc.Programming module #5 (Pro 5)
is used to set up the integrator. The re-transmitted analog output is
specified to drive a chart recorder with 4-20 mA for a hard copy of
temperature profiles for later evaluation.

-22-

PROCESS CONTROL EXAMPLE

Four IMRs are used to control a Plastic Injection Molding
Process. The raw material (Thermo-Plastic Resin) is contained
in a bulk storage bin and is removed and prepared for mold
injection by a screw feed. While the material is inthe screwfeed,
band heaters, placed around the screw barrel and controlled by
IMR RTD indicators, gradually melt the material. The
temperature of the material must be brought up to injection
temperature in three stages, 300, 400, and finally, 500 degrees.
Using the controlled relay outputs of three IMRs, the various
temperatures of the bands are controlled precisely. After the
material is injected into the mold, the mold temperature must fall
below 250 degrees before the mold can be opened and the part
removed. A fourth IMR is used to control actuators which open
the mold andeject the partand restart the moldingcycle when the
mold temperature falls below the temperature threshold. After
the process is set-up and running properly, the indicators can be
programmed into the “quick programming” mode to allow
modification to setpoints and deadband only, if desired.

INTEGRATOR /TOTALIZER / PEAK/VALLEY/ TEMPERATURE OFFSET (Optional)

INTEGRATOR/TOTALIZER

The integrator/totalizer option simply adds input readings together using a
programmable time base and scaling coefficient. The decimal point position of
the integrator/totalizer can be programmed independent of the scaled input
signal. The integrator/totalizer may be reset through a remote input, by the front
panel or through the serial communications option. Alarms may be programmed
to triggerfrom integrator/totalizer values; forexample to total “degreeminutes”
for batching operations. The programmable time bases are “per second”, “per
minute” and “per hour”, meaning the integrator/totalizer will accumulate at a
fixed rate of
selected time period. For example, if the input is a constant 100° and the “per

1

times per second and be equal to a fixed input level over the

2

2

minute” time base is selected, the integrator/totalizer will accumulate at the rate
of 100° per minute. The totalizer is updated at this rate every 400 msec. As a
result, the input is accumulated in “batches” of 6.6 counts every 400 msec.
Therefore, the totalizer start and stop sequencing, as well as alarm values set for
triggering at specific totalizer values, are only accurate to the 400 msec totalizer
update rate. The preceding example requires a scale factor of 1.000 to yield exact
time bases, but any scale factor can be used to span between the ranges. (See
section on integrator/totalizer programming for detailed information.) A
programmable low temperature level disable feature completes the
integrator/totalizer features (this will stop totalization when the input drops
below this programmed value, “low cut”). At loss of power to the indicator, the
contents of the integrator/totalizer issaved. Thiswill allow integrating/totalizing
of interrupted processes. The total can accumulate to 999,999. If the low-end
cut-out value is programmed negative (ex. -100, reference Program Module #5),
and the input signal is between zero and the low-end cut-out value, the totalizer
value will decrement. If the input signal goes above zero the total will increment.
If the signal goes below (more negative than), the low-end cut-out value,
totalization will stop.

PEAK/VALLEY

The other features of the integrator/totalizer option are peak and valley
detection. The indicator will record the lowest reading (valley) and the highest
reading (peak), automatically, for later recall. This information is valuable in
monitoring the limitsof theprocess over any length of timesince thesevalues are

stored at power-down to span over shifts, days, etc. An external input can be
programmed to reset or engage the unit into a peak/valley reading indicator.
Additionally, thepeak andvalley can be viewed and reset from the front panel, if
so programmed, and viewed and reset from the serial communication option.

Note: The peak/valley measurement is not instantaneous, and is based on a

nominal 2 sec. response time.

OFFSET AND SLOPE DISPLAY TEMPERATURE

This feature allows the operator to manipulatethe displayed temperature reading.
The operator may utilize this feature for example, when switching RTD probes, to
compensate for differences in RTD probe accuracy from one manufacturer to
another or to offset the input reading to match a “Reference” temperature.

The displayed temperature can be offset either positive or negative to the
actual measured temperature. Programming a positive number for the offset
value increases the display value. Programming a negative number for the offset
value decreases the display value. For example, if the displayed temperature is
10° less than the measured temperature, programming a +10 for the offset value
will increase the displayed value by 10 throughout the entire range. If the
displayed temperature is 10° higher than the measured temperature,
programming a -10 for the offset value will decrease the display value by 10
throughout the entire range.

If a difference exists between the displayed temperature and a reference
temperature point, the display may be offset for this effect. Similarly, a
correcting “slope” may be programmed, with the offset, to allow for two point
temperature correction.

For most applications, the slope and offset values are not changed. But if it is
required to scale the display to match a calibrated probe, the following formula
and example show the calculation of appropriate slope and offset values.

Desired Display = (slope x actual temp. display) + offset

difference of two desired temperature points

slope =

offset = one desired temperature point - (slope x one

-24-

difference of two actual temperature points

corresponding actual temperature point)

Example:

The meter is displaying 502 degrees and 696 degrees (actual temperature)
when the calibrated temperature reference shows that 500 degrees and 700
degrees respectively should be displayed (desired temperature).

First determine the new slope value using the sets of temperature points.

700 - 500

slope =

696 - 502 194

Next, determinethe new offset value byusing either one of the temperature pairs.

offset = 700 - (696 x 1.0309)

offset = 17.5

INTEGRATOR/TOTALIZER EXAMPLE

The indicator is employed to indicate average daily (8 hour) temperature of a
“Hot Room” usedfor storing variousingredients at alarge food processing plant.

Ingredients which must be kept at temperatures above 100.0°F are stored in this

INTEGRATOR/TOTALIZER SET-UP (Cont’d)

The integrator/totalizer will accumulate up to 99999.9. At the end of the shift,
the average temperature over the previous 8 hours can be read directly. The
integrator/totalizer can then be reset for thenext eighthour shift. Anytime during
the shift, the average temperature can be calculated by the following formula:

Av =

ALARMS (Optional)

The alarm option consists of an additional printed circuit board with nine
terminals. Six of these terminals are the two Form-C relays and the other three are
the two open collector transistors, which act in parallel with the relays. The two
alarms are completely independent with programmable values, hysteresis
(deadband), high or low acting,auto ormanual reset, triggeringfrom input or total,
and tracking one another, if desired. If the alarmsare programmed tolatch (manual
reset), then they will have to be reset either by the front panel or remote input. The
alarms can be made to trigger from the integrator/totalizer instead of the input, to
activate external alarms, control valves, etc. Additionally, the alarms may be
programmed to activate an alarm display to alert operators of the condition.

Alarm #1 can be madeto track Alarm #2 by enablingalarm tracking. This is useful
in alarm set-ups where a pre-warning control activates before a second alarm shuts
off the process. When tracking is programmed, changing the shut-off trip value

ALARM TIMING DIAGRAMS

(Alarm #2)automatically changes Alarm #1 so that the offset between Alarm #2and
Alarm #1 remains the same. Alarm and hysteresis values can be modified through
the optional serial communications to provide automatic control. The following
diagrams depict how the alarms work with both “HI” and “LO” acting set-ups.

Programming of the alarms can be accomplished in the normal programming
mode “Pro 6” or the unit can be programmed so that the values can only be
changed in the “quick programming” mode.

If the display should indicate an “OPEN” or “SHort” the alarms will
de-energize, whether they are latched or unlatched.

Note: Alarm Comm. (TBB #8) must be kept isolated from analog “-”.

20 mA CURRENT LOOP SERIAL COMMUNICATIONS (Optional)

GENERAL DESCRIPTION

The serial communication option is a half-duplex, two-way, 20 mA loop that
can connect to a variety of printers, computers, terminals and controllers to suit
many data-polling orautomatic operationapplications. The indicatorresponds to
a host of commands, including change alarm value, reset totalizer and transmit
input value.Two loops are required for all hook-ups; a transmit (out-going data)
loop and a receive (in-coming data) loop. Since the indicator monitors the
receive loop for a busy signal (current interrupted) while transmitting, the
receive loop must be connected even if the indicatoris transmitting only, such as
to a printer. A built-in 20 mA source can be used in the transmit loop (only) by
connecting the currentreturn wire to-20 mA SRC.,instead of SO+. Tobypass the
built-in current source, make transmit loop connections to SO+ and SO-.
Additionally, multiple units and other Red Lion Controls instruments can be
serially addressed, up to a maximum of 99 units. (The actual number in a single
loop is limited by the serial hardware specifications.) To eliminate problems
with ground loops, the serial circuitry is isolated from both signal common and
output common. Optional 20 mA to RS232C and 20 mA to RS422 converter
modules expand the unit’s flexibility.

Note: When operating the unit with a printer, the receive loop of the indicator

must have current flowing into it before transmission can take place.

COMMUNICATION FORMAT

Data is sent by switching current on and off in the loop and is received by
monitoring the switching action and interpreting the codes that are transmitted.
In order for data to be correctly interpreted, there must be identical formats and
baud rates among the communicating equipment. The only formatavailable with
this indicator is 1 start bit, 7 data bits, 1 odd parity bit and 1 stop bit. The baud
rates are programmable and the choices are: 300, 600, 1200 and 2400.

DATA FORMAT-10 BIT FRAME [300, 600, 1200, 2400 Baud]

Before serial communication can take place, the indicator must be
programmed to the same baud rate as the connected equipment. In addition, the
loop address number, print options and full or abbreviated transmission must be
programmed. If only one indicator is to be used, then a loop address number of
“0” may by used, to eliminate the requirement for the address specifier when
sending a command. If more than one indicator is on the loop, assignment of
unique addresses, other than zero, for each indicator is recommended. Valid
addresses of 0 to 99 may be assigned, but the built-in current source, if used, is
capable of driving up to 7 units. Additional drive capability may be afforded by
an external current source with a higher compliance voltage. Refer to
programming section “Pro 7” to program the serial option.

-28-

SENDING COMMANDS TO THE IMR

When sending commands to the unit a command string must be constructed.
The command string may consist of command codes, value identifiers, and
numerical data. Belowis a table outliningthe codesthe indicator will recognize.

COMMAND FUNCTIONS

T transmits the requested information specified by the identifier

V change a value specified by the identifier (C-F, K, & L)
N address a particular indicator in a multiple unit loop (0-99)
R reset a value specified by the identifier (B-D, G, H, I, & J)
P print per programmable print options (A-I)

VALUE IDENTIFIERS SERIAL MNEMONICS

Note: RJ - offset the input (re-zeros). When the input is offset (via front panel or

“RJ”) the amount is stored in the offset reading (I). Ex. When an offset is

performed, the display reads “5.0”, the offset value will be “-00005.0” (and

the display will show 0.0).

A command string is constructed by using the above commands and
identifiers along with any data values thatare required. The indicator will accept
“+” or“-” infront of the data value. Numberswithout “+” are understood to be
positive. Leading zeros can be eliminated and both lower and upper case
characters are accepted. The address command is used toallow a command to be
directed to a specific unit on the loop. If the indicator is assigned an address of
“0”, transmission of the address command is not required. This is done where
only one indicator is in the loop.

(A-I, K, & L)

A temperature RTD
B integrator/totalizer TOT
Calarm#1 AL1
Dalarm#2 AL2
Ehysteresis#1 HS1
Fhysteresis#2 HS2
G peak reading PEK
H valley reading VAL

I zero offset OFS
J offset input —
K analog low ANL
L analog high ANH

The command string is constructed in a specific logical sequence. The
indicator will reject command strings that do not conform. Only one operation
can be performed per command string. Below isa description of how to construct
a command string.

1. If theindicator has an addressother than zero, thefirst two characters of the

string must consist of the address command (N) followed by the unit

address number (0-99). If the indicator has an address of 0, the address

command is optional.

2. The next two characters in the string are the actual command the indicator

must perform and the identifier on which it operates. Command P-print,

Value I-zero offset and J-offset input, have implied operators and need no

additional characters.

3. If the change value command is being used (V), the next characters in the

string after the value identifier, are the numerical data. When sending

numerical data, suchas change an alarm value, the correct number of digits

to the right, must be included. As an example, to change an alarm value

from 750.2 to500.0. Sending 500 would causethe indicator to see 50.0 and

change the alarm value accordingly.

4. All commands must be terminated by an asterisk(*). The indicator will not

respond to any other code. Carriage return and line feed are not valid

terminators and should be suppressed with the character “;”,ifusinga

BASIC print statement (ex. Print “N9TA*”;).

COMMAND STRING EXAMPLES

Indicator with address 3, transmit temperature reading.

N3TA*

Indicator with address 0, change alarm #1 to 1500.

VC1500*

Indicator with address 1, reset totalizer.

N1RB*

Indicator with address 99, print the print options.

N99P*

Indicator with address 0, zero the offset value.

RI*

-29-

If illegal commands or character is sent to the IM, an asterisk (*) must be sent to
clear the input buffer. The IM will not respond to an illegal or incomplete
transmission. The diagrams show the difference in the timing considerations for
either Abbreviated or Full CharacterTransmission, or ifa ResetCommand isissued.

RECEIVING DATA FROM THE IMR

Data is transmitted from the indicator whenever a “T” or “P” command is
received via serial communications or a remote input, E1-CON or optional
E2-CON pin is programmed for print request, is activated. If the abbreviated
transmission was programmed, just data will be transmitted with no built-in
delay. (If full transmission is programmed, then there is a 400 msec min to 800
msec max delay built-in to the string.)

A data string transmission is shown below.

The first two characters transmitted are the unit address number, unless it is
zero, in whichcase itis leftblank. Then two blank spaces are sent. The next three
characters are the abbreviation for the value (mnemonics), which is then
followed by a blank. The actual data is transmitted next. The field is right
justified with leading zeros. Negative numbers are indicated by a minus sign
fixed next to the identifier. A carriage return and a line feed are transmitted next.
For various reasons, “extra” characters are added onto the end of the above
character string. (These characters could be and are used for control or signaling
purposes.) These characters are:
< CR> sent after single line transmissions from IM unit.
< SP>< CR>< LF> sent after “last line of a block” transmission from IM unit.

For a “T” commandor after each “line of a block” transmission, no additional
characters are sent. If the abbreviated transmission is selected, the address,
mnemonics, and any blankspaces (first eight characters) arenot transmitted (the
data strings are left justified in this case).

If the transmitted data is overrunning the peripheral’s buffer, the receive
channel to the indicator may be used for handshaking purposes. As a
consequence of this, even if the indicator is to transmit only (ex. to a printer),
current must be flowing in the receive channel to allow transmission. Examples
of transmissions are as follows:

2 RTD -125.7F < CR> < LF > full transmission

-125.7 < CR> < LF > abbreviated transmission

CURRENT LOOP INSTALLATION

WIRING CONNECTIONS

It is recommended that shielded (screened) cable be used for serial
communications. This unit meets the EMC specifications using Alpha #2404
cable or equivalent. There are higher grades of shielded cable, such as four
conductor twisted pair, that offer an even higher degree of noise immunity.

When wiring the 20 mA current loop, remove the bottom terminal block
(TBA), located on the rear of the unit. Refer to the numbers listed with the
terminal descriptions below or those located on the label. Install each wire in its
proper location on the terminal block. When all connections are made, replace
the terminal block into its proper location.

SERIAL COMMUNICATIONS EXAMPLE

PROCESS CONTROLLING SYSTEM

Six Model IMRs with Serial Communication Option are
used to monitor and control the temperature of 6 ovens at a
large bakery. The IMRs are located at each of the ovens in
the production area of the building. The communications
lines are run to an industrial computer located in the
production offices.

The drawing belowshows the CurrentLoop set-up. Each
IMR is given an address and programmed accordingly
(Program Module #7). A baud rate of 1200 is selected.

An application program is written, which sends and

retrieves data from the IMRs.

Note: On all IM indicators,the SO+ and the +20mA SRC

are connected internally. Thereforeit is notnecessary
to have this terminal tied to any other terminal on the
unit if that unit is serving as the loop supply source.

-33-

RE-TRANSMITTED ANALOG OUTPUT (Optional)

The re-transmitted analog output option transmits a digitally programmable 4
to 20 mA or 0 to 10 VDC signal to drive chart recorders, remote indicators and
controllers. The option is contained on the upper PCB and has two outputs,

“ANALOG-” (TBB #10) and “ANALOG+” (TBB #11) and is self-powered
(active) with acompliance of 10 VDC.The analog“-” outputis isolated from the

input common, eliminating problems from ground loops. Programming of the
option is performed in “Pro 8” of the normal programming mode. Display
values are simply keyed into provide a 4 mAor 0VDC output, “AN-Lo”,anda20
mA or 10 VDC output, “AN-HI”. The analog output then follows the assigned
value and as such will update every measurement cycle. Nonstandard current or

ANALOG OUTPUT DIAGRAMS

voltage ranges can be supported by calculating the slope and intercept of the
display/output and calculating the required display values at 4 mA (0 VDC) and
20 mA (10 VDC). Reverse action can be achieved by programming a “high”
display value for “AN-Lo” and a “low” display value for “AN-HI”.

If the display should indicate an “OPEN” or “SHort” the analog output will

go to 20 mA (10 VDC) for an open and 4 mA (0 VDC) for a short.

Note: Analog “-” must be kept isolated from Alarm Comm. (TBB #8).

-34-

ANALOG OUTPUT CALIBRATION

Although the analog output has been calibrated at the factory, zero and span
adjustments are provided to compensate for small offsets and drifts. If excessive
drift is noticed, the following calibration procedure may be performed.

Scale the analog output by entering an arbitrarily larger display value for

“AN-HI” then for “AN-LO”, in “PRO 8”.
Note: Set the analog output source assignment for input.

4 to 20 mA Calibration

Exit the programming mode and apply a (temperature)/(resistance) to the
input of the indicator so that the display readingis belowthat of the value entered
for “AN-LO”. Adjustthe zero potentiometer (rightside) so that exactly 4.00 mA
flows, as verified by an accurate ammeter. Next, apply a (temperature)/
(resistance) to the indicator so that the display reading is above that of the value
entered for “AN-HI”. (See Appendix “B” for max. input voltage.) Adjust the
span potentiometer (left side) so that 20.00 mA is flowing. Repeat the zero and
span adjustments untilboth are accurate.Analog output calibration is complete.

0 to 10 VDC Calibration

Exit the programming mode and apply a (temperature)/(resistance) to the
input of the indicator so that the display readingis belowthat of the value entered
for “AN-LO”. Adjustthe zero potentiometer (rightside) so that exactly 0.00 VDC
flows, as verified by an accurate voltmeter. Next, apply a (temperature)/
(resistance) to the input of the indicator so that the display reading is above that of
the value entered for “AN-HI”. (See Appendix “B” for max. inputvoltage.) Adjust
the span potentiometer (left side) so that 10.00 VDC is flowing. Repeat the zero
and span adjustments until both are accurate. Analog output calibration is
complete.

APPENDIX “A” - INSTALLATION & CONNECTIONS

INSTALLATION ENVIRONMENT

The unit should be installed in a location that does not exceed the maximum
operating temperature and provides good air circulation. Placing the unit near
devices that generate excessive heat should be avoided.

The bezel should be cleaned only with a soft cloth and neutral soap product.
Do NOTuse 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 unit.

Before installing the IM into the panel, the user should first become familiar
with the unit. It may also be desirable to program the unit for the application.
When programming is complete, all parameters will be saved in non-volatile
memory. The Program Disable (PGM.DIS.) terminal should be connected to
COMM. to prevent accidental or unauthorized programming changes.

PANEL INSTALLATION

SELECT AC POWER (115/230 VAC)

The AC power to the unit must be selected for either 115 VAC or 230 VAC.
The selector switch is located through an access slot on the side of the case (See
figure above or label on case). The unit is shipped from the factory with the
switch in the 230 VAC position.

The unit meets NEMA 4/IP65 requirements for indoor use, when properly
installed. The units are intended to be mounted into an enclosed panel with a
gasket to provide a water-tight seal. Two mounting clips and screws are
provided foreasy installation.Consideration shouldbe givento the thickness
of the panel. A panel which is too thin may distort and not provide a
water-tight seal. Recommended minimum panel thickness is 1/8".)

After the panel cut-out has been completed and deburred, carefully slide the
gasket over the rear of the unit to the back of the
bezel. Insert the unit into the panel. As depicted
in the drawing, install the screws intothe narrow
end of the mounting clips. Thread the screws
into the clips until the pointed end just protrudes
through the other side. Install each of the
mounting clips by inserting the wide lip of the
clips into the wide end of the hole, located on
either side of the case. Then snap the clip onto
the case. Tighten the screws evenly to apply
uniform compression, thus providing a
water-tight seal.

Caution: Only minimum pressure is required to seal panel. Do NOT

overtighten screws.

Caution: Make sure the AC selector switch is set to the appropriate

position before applying power to the unit. Damage to the unit
may occur if the AC selector switch is set incorrectly.

-36-

EMC INSTALLATION GUIDELINES

Although this unit is designed with a high degree of immunity to
ElectroMagnetic Interference (EMI), proper installation and wiring methods must
be followed to ensure compatibility in each application. The type of electrical
noise, source or coupling method into the unit may be different for various
installations. In extremely high EMI environments, additional measures may be
needed. The unit becomes more immuneto EMI with fewerI/O connections. Cable
length, routing and shield termination are very important and can mean the
difference between a successful or a troublesome installation. Listed below are
some EMC guidelines for successful installation in an industrial environment.

1. The unit should be mounted in a metal enclosure, which is properly

connected to protective earth.

a. If the bezel is exposed to high Electro-Static Discharge (ESD) levels,

above 4 Kv,it should be connected to protective earth. This can be done
by making surethe metalbezel makes propercontact to thepanel cut-out
or connecting the bezel screw with a spade terminal and wire to
protective earth.

2. Use shielded(screened) cables for all Signal and Controlinputs. 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.

a. Connect the shield only at the panel where the unit is mounted to earth

ground (protective earth).

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 unit and leave the other end of the

shield unconnected and insulated from earth ground.

3. Never run Signal orControl cables in the same conduit or raceway withAC

power lines, conductors feeding motors, solenoids, SCR controls, and

heaters, etc. The cables should be run 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 away

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. Installline filters on the power input cableto the unit
to suppress powerline interference. Install themnear 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 (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 #1VR3

Note: Reference manufacturer’sinstructions wheninstalling a linefilter.

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.
Snubbers:

RLC #SNUB0000

-37-

WIRING CONNECTIONS

After the unit has been mechanically mounted, it is ready to be wired. All
conductors should meet voltage and current ratings for each terminal. Also
cabling should conformto appropriate standards ofgood installation,local codes
and regulations. It is recommended that power supplied to the unit be protected
by a fuse or circuit breaker. All wiring connections are made on removable
plug-in terminal blocks. There is a separate terminal block for the bottom board
(TBA) and optional top board (TBB). When wiring the unit, remove the terminal
block and use the numbers on the label to identify the position number with the
proper function. Strip the wire, leaving approx. ¼" bare wire exposed (stranded
wires should be tinned with solder). Insert the wire into the terminal and tighten
down the screw until the wire is clamped tightly. Each terminal can accept up to
one 14-gage, two 18-gage or four 20-gage wire(s). After the terminal block is
wired, install it into properlocation onthe PCboard. Wireeach terminalblock in
this manner.

POWER WIRING

Primary AC power is connected to terminal 1 and 2 (marked VAC 50/60 Hz,
located onthe lefthand sideof thebottom terminalblock). Toreduce thechance of

noise spikesentering the AC line and affecting theindicator, theAC power should
be relatively“clean” and within the specified 10% variationlimit. Drawing power
from heavily loaded circuits or circuits which also power loads that cycle on and
off, (contactors, relays, motors, machinery, etc.) should be avoided.

USER INPUT WIRING

User inputs (PGM.DIS., E1-CON, and optional E2-CON) are digital inputs
that are active when connected to TBA #5 Common. Any form of mechanical
switch, sinking collector logic with less than 0.7 V saturation may be used. The
use of shielded cable is recommended. Follow the EMC Installation Guidelines
for shield connection.

Basic Connection

Connection w/3-Wire Sensor

-38-

OUTPUT WIRING

Relay Connections

To prolong contact life and suppress electrical noise interference due to the
switching of inductive loads, it is good installation practice to install a snubber
across the contactor. Follow the manufacturer’s instructions for installation.

Note: Snubber leakage current can cause some electro-mechanical devices

to be held ON.

SIGNAL WIRING (RTD SENSOR)

RTD sensors are used in applications where a high degree of accuracy is
required. Most RTD sensors available are the 3-wire type. The 3rd additional
wire is a sense lead for cancelling the effects of lead resistance at the probe. The
sense lead connects to TBA #6 (+ signal),thecommontoTBA#7(­signal/comm), and the excitation to TBA #5 (+ excitation). The excitation and
sense leads are generally the same color because they are functionally the same
and maybe interchanged at the instrument. Four wire sensors have an additional
sense lead connected (at the probe) to the common lead. Leave the extra sense
lead disconnected when using a four wire probe with the IMR.

Always refer to the sensor manufacturer’s instructions for probe wiring
connections, if available.

Two wire RTD sensors may be used with theIMR byshorting TBA #5 to TBA
#6, if the distance between sensor and instrument is not too great (<30ft).The
total lead resistance can be used to predict the temperature error for 2-wire
sensors, according to 2.5°C/W of lead resistance.

Note: Extended cable runs can be made provided the lead resistance is less than

20W/lead andthe resistance is equal in each lead. For further information see

“Appendix B - Specifications” or consult factory.

APPENDIX “D” - PROGRAMMABLE FUNCTIONS

Programming of the indicator is divided into modular steps.Each moduleis a
short sequence of data entries. The front panel buttons “UP” and “DOWN”
(shown as “arrows”on the front panel) areusedtochangethedataandset-ups,
while the “P” buttonisusedtosave or enter the data. Afterpressing “P”,which
gains entry into the programming mode, the programming modules are
identified by the message “Pro” and a number in the display. “UP” and
“DOWN” are used to selectthe desired programmingmodule and“P” isused to
enter it. All of the subsequent programming steps follow the same procedure.
The rear terminal labeled “PGM. DIS.” must be ungrounded to gain access to
programming. The following table lists the programming steps.
