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

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.)

“HyS-1” < > “1” to “9999”

ALARM #1 HIGH OR LOW ACTING

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.
