PC-Programmable RTD, T/C, Ohms, mV
and Potentiometer Limit Alarm Trips

Introduction

This is the users’ manual for the Moore Industries
CPA PC-Programmable Alarm (TPRG: RTD, T/C,
mV, Ohms and Potentiometer Limit Alarm Trips). It
contains all of the information needed to confi gure,
install, operate, and maintain this instrument.

About this Manual

Wherever you see a “ Note”, “ Caution”, or “ WARNING
” pay particular attention.

WARNING - Hazardous procedure or condition that
could injure the operator.

Caution - Hazardous procedure or condition that could
damage or destroy the unit.

Note - Information that is helpful for a procedure,
condition, or operation of the unit.

The CPA

The CPA (TPRG) is a PC-Programmable, user­confi gurable alarm. The instrument includes two
alarm (relay) outputs and an optional analog output.
The alarms can be confi gured as trip or fault alarms.

Figure 1. The CPA (TPRG)

The CPA has a READY LED to indicate the health of
the unit, an INPUT LED to indicate the status of the
input and a dual color LED, per relay, to indicate alarm
status.

Model and Serial Numbers

Moore Industries uses a system of model and serial
numbers to keep track of all of the information on
every unit it sells and services. If a problem occurs
with your CPA, check for a tag affi xed to the unit
listing these numbers. Supply the Customer Support
representative with this information when calling.

Inputs

Refer to Table 3 of this manual for input ranges and
accuracies of the CPA (TPRG).

Options

Analog Output (-AO)

The analog output range of the CPA (TPRG) can
be voltage or current. The current output is a
confi gurable source or sink output. Four terminals
are provided to allow voltage/current and current sink/
source selection without the need for jumpers. The
output can be confi gured to narrower spans from the
PC Confi guration program. The range of the current
output is 0–24mA. The range of the voltage output is

-0.5–11V.

RF Option (-RF)

An RF option is also available. This version provides
30V/m RFI/EMI immunity compared to our standard
model which offers 10V/m RFI/EMI immunity.

Confi guring the CPA

One of the benefi ts of this alarm is that there are no
internal or external controls to adjust or settings to
change. All operating parameters are set using a PC
and Moore Industries’ Intelligent PC Confi guration
software.

4-Wire RTD or

Decade Resistance Input

Potentiometer Input

The software settings are downloaded to the
instrument in the form of a Confi guration File and
stored in the instruments’ memory. You can save a
backup copy of the fi le on your PC hard drive or disk.
The alarm communicates with the PC through an RS­232 connection to the PC’s serial port.

Installing the Confi guration Software

Refer to Table 5 for the equipment needed.

1. I

nsert the Moore Industries Interface Solution
PC Confi guration Software CD into the CD
drive of the PC. Access the CD and open the
“CPA CPT PC Confi guration Software” folder.

2.

Double-click the installation program located
in the folder. Follow the prompts to correctly
install the program

Once the Confi guration Program is installed on the
PC, the CPA can be connected to equipment to
simulate input and monitor output. You can then
change the operating parameters of the alarm.

No Alarm Needed

It is not necessary to connect the CPA to a PC to
create confi guration fi les using the software. The
Confi guration Program can be run without connecting
an alarm, and most parameters can be set without
benefi t of input from a sensor or CPA.

.

This makes it easy to create a set of operating
parameters, save them to disk, and download them to
one or more instruments at a later time.

The CPA must be connected to the PC in order to:
trim input, trim output, assign a tag, perform a loop
test, receive (via download) a confi guration fi le, and
save the confi guration fi le from the alarm’s memory.

Connecting the CPA to the PC

Connect the RS-232 end of the cable to the PC’s

COM port.

See Table 5 for information on the necessary
equipment.

PC Confi guration Software Summary

Figure 5. Most of the CPA (TPRG) Operating Parameters can be set from the Main Screen of the Confi guration Program

Once the default confi guration has been saved to
disk, it is safe to program other parameters. The PC
Software is made up of these sections:

1. Status– This portion of the program displays the
activity of the connected unit. It will show the COM
Port being used and the Measurement Mode.

2. Measurements– Displays current software
processes and indications. Allows you to select
the decimal place of your process variable (Decimal
Places (PV)) indication and monitor up to two
confi guration variables (Monitored Vars).

3. Device Information– This “read-only” display
indicates fi rmware version, hardware revision,
serial number, calibration date, software version,
confi guration date and the last confi guration source.

4. Communication– From here you may enable Start
Measurements and Stop Measurements, upload your

confi guration to PC or download your confi guration to
the unit, save your confi guration to a fi le, and print out
your confi guration settings.

5. Input Confi guration– Set 50/60Hz Rejection
Selection and selection of °C or °F. Allows you to
choose input type. You may also enable Input Trim,
Output Trim, Custom Table and Broken Wire Test
functions.

6. Device Confi guration– Use this parameter to
place an identifying “Message” (32 alphanumeric
characters max.), select an “I.D. Tag” (8 alphanumeric
characters max.) and a “Descriptor” (16 alphanumeric
characters max.).

7. Output Confi guration– Use this section to select
your output confi guration and output limits.

8. Output Level if Failure– Used to select
confi guration of Upscale/Downscale Drive failure
detection of sensor or sensor wiring. Refer to Output

Level if
Failure section for a complete description.

9. Broken Wire Test Override- Allows you to enable
or disable the Broken Wire Test by clicking the “BW
ON” or “BW OFF” buttons. Refer to the Broken Wire
Test Override section for a complete description.

10. Alarm Parameters– Use this to choose an
alarm mode and confi gure as either a Trip, Fault or
Band alarm. Select whether to use as a Fail Safe or
NON Fail Safe Alarm. You may also choose a Delay
(0-120sec) and a Deadband (0-100%). Refer to the
Alarms section for a complete description.

11. Trimming/Damping Tab– Selecting this
parameter allows you to perform Sensor Trim, Output
Trim and Output Damping functions. Refer to the
Trimming/Damping section for a complete description.

12. Custom Table Tab– The CPA has two modes of
operation: linear mode and custom mode. In linear
mode, the scaled output is proportional to the scaled
input. In custom mode, reached by selecting the Cus-
tom Table Tab, you defi ne a special linearization func­tion. Refer to the Custom Table section for a complete
description.

Confi guration

Output Level if Failure

In the Output Level if Failure section you will notice
Down Scale and Up Scale selection. Using its output,
the CPA can be confi gured to provide a special
warning of a breakdown or failure. Use this setting to
confi gure the instrument to drive its output either up or
down when a failure is detected. For current outputs,
limits are 3.6mA (downscale) and 23.6mA (upscale);
for voltage outputs, limits are -0.5V (downscale) and

11.0V (upscale).

When a failure is detected, the “Fail Last” feature, if
enabled, holds the last measured value before the
failure occurred.

If the “User Selected” feature is enabled, you may
enter any value, within the range, to view at the output
when a failure is detected.

Broken Wire Test Override

During operation, the CPA sends random microamp
pulses through input wiring to check for broken wiring
or a burned out sensor.

Upon power-up Broken Wire Test is enabled. If a
problem is detected, “Broken Wire Failure” in the
Process Information section of the confi guration
program will light to indicate a problem. The Broken
Wire Test may be temporarily disabled by clicking the
“BW OFF” button in the Broken Wire Test Override
section.

Note:

Once you have confi gured all parameters,

download to the unit by either selecting “Download

Confi guration” in the Confi guration dropdown menu

located in the Communications bar or by clicking the

button.

PC-Programmable RTD, T/C, Ohms, mV
and Potentiometer Limit Alarm Trips

Alarms

Trip Low and Trip High Alarms

In the Alarm Parameters portion of the Confi guration
Program you may choose a “Trip Low” and “Trip High”
limit. In choosing your limits you are setting the
parameters for your unit to notify you if your process
input drops below (Trip Low) or exceeds (Trip High)
your trip point setting.

Deadband

Deadband (0-100%) is a type of buffer zone. It allows
an alarm to remain tripped even after the process
input has returned to, or passed, the trip point. If
no deadband is set, the alarm will reset itself once
reaching the trip point.

Fail Safe/NON Fail Safe Alarms

A Fail Safe alarm, if in the alarm condition, will remain
in the alarm condition even if power to the unit is
removed.

The Band Alarm is activated when the Process
Variable is outside of the Low/High Trip point ranges.
The Trip Low is always lower than the Trip High and
their deadbands are inside the range of Low/High Trip.
The span between the Low and High Trip is not limited
which allows control of measurements in a very narrow
range.

The two alarms can be set in any combination. For
example, Alarm 1 can be set as the Band Alarm and
Alarm 2 as the Fault Alarm. Conversely, both alarms
can also be set as Band Alarms.

The HI/LO Alarm can be used when the input signal
reaches a critical level. The HI/HI / LO/LO Alarm is
used to provide early warning that an action is required
before a dangerous level is reached. See Figure 7 for
details.

Figure 7. Two Alarm Functionality Graph

Fail Safe alarm trip relays are energized whenever the
process input is in a non-alarm condition (including
any deadband setting). These relays de-energize
when the process input trips the alarm.

NON Fail Safe alarm trip relays are energized
whenever the process input is in an alarm condition.
These relays de-energize when the process input
returns to the reset point (including any deadband).

Band Alarm

The Band Alarm incorporates Low and High Trip
points, Deadband and Delay (0-120sec).

The Band Alarm combines two Trip Alarm settings.
The fi rst alarm is always confi gured as Low Trip
(Trip Point Low) and the second as High Trip (Trip
Point High). See Figure 6 for information on alarm
parameters.

CPA

PC-Programmable RTD, T/C, Ohms, mV

and Potentiometer Limit Alarm Trips

To access the Trim feature, click the Trimming/
Damping tab . Trimming increases the measurement

accuracy of the parameter you are trimming by
either matching the reading of its actual input to its
scaling (Sensor Trimming) or calibrating the output
to the device receiving the output (Output Trimming).
Damping allows you to introduce a delay into the
response of your transmitter in order to stop short­lived spikes from setting off alarms. Refer to Figure 9
for hookup.

Sensor Trim

Sensor Trimming increases the measurement
accuracy of your CPA by matching the reading of
its actual input to either a calibrated source or the
device to which it is connected. This verifi es that the
input from the sensor to the alarm is being interpreted
correctly.

The CPA can trim any point along the scale. Note
that one-point trimming applies an offset to the sensor
reading, while two-point trimming applies both an
offset and a gain.

Before you attempt to perform the Sensor Trim
function ensure that the Status section of the screen
indicates “Measurements On”. Sensor Trim can be
done only when the measurements are on. To do this
click the Mode dropdown box, from the menu bar, and
select “Measurements On”.

1. Select either one trim point or two trim points by
clicking the appropriate button. Each pair consists of
“trim” and “captured” values.

2. Enter the values that need to be trimmed into the
corresponding fi elds.

3. Apply the targeted signal to the input, wait until
it settles and click “Point 1 Trim” to capture the
measured value. If you chose “Two-point Trim” repeat
the step above for the second point and click “Point 2
Trim”.

4. To enable input trim and the values stored, click the
“Input Trim ON”.

Output Trim

Output Trimming increases the measurement accuracy
of your CPA by calibrating its analog output to the
device that is receiving the output. This ensures that
the instrument is being correctly interpreted.

Before you attempt to perform the Output Trim
function ensure that the Status section of the screen
indicates “Measurements Off”. To do this click the
Mode dropdown box from the Menu bar and select
“Measurements Off”.

1. Select either “Output: mA” or “Output: V”, whichever
is appropriate for your application.

2. Attach a multimeter to the analog output and select
the “4mA” or “0V” button. Use the scroll bar to trim the
measured output to your desired value.

3. With the multimeter still connected select the
“20mA” or “10V” button. Use the scroll bar to trim the
measured output to your desired value.

4. To enable Output Trim and the values stored, click
the “Output Trim ON”.

5. Set Status back to “Measurements On”.

If selected, the user trim values will be used and the
manufacturer settings will be nullifi ed.

Loop Test

A Loop Test may be performed in order to check
output performance and accuracy and to trim other
instruments in the loop. Your output will be a current
value, in mA, or a voltage equal to the value you input.
You can check the other current devices on the loop
and calibrate them to this signal.

This feature is independent of the input. If you fi nd
that the output requires adjustment you may perform
the Output Trim function.

1. To use the Loop Test function select the Mode
dropdown box in the Communications bar and select
“Measurements Off”.

2. Next, in the “Output Value %” box, type the
percentage of the output value you wish to test. You
may also use your mouse, left click and adjust the
scroll bar to adjust to your desired value. Hit “Enter”.

3. In the “Output Value” box enter the value, within
your confi guration range, that you wish to signify as
your output value. Hit “Enter”.

4. Perform your test and calibration.

5. When you are fi nished, return to Mode in the
Communications bar and reset your status to
“Measurements On”.

Output Damping

Output Damping allows you to introduce a delay into
the response of your unit in order to stop short-lived
spikes from setting off alarms. Output Damping is
activated when the value set in the “Output Step
Threshold” fi eld is exceeded.

1. To enable output damping, select the “Enabled”
button. If you do not wish to use the damping feature,
then select “Disabled”.

2. Insert a value between 1 and 16mA in the “Output
Step Threshold” fi eld. This is how much of an output
step change is allowed in a specifi ed time frame
before fl agging the software.

3. Insert a value between .5 and 120sec in the
“Damping Sec” fi eld. This is the amount of time it will
take for the output to reach 63% of the step output
change once the input exceeds the value in the
“Output Step Threshold” fi eld.

By checking the appropriate box in the Other Damping
Options section, you may also choose to select Output
Damping to occur upon power up or start up from
a PC, upon broken wire failure detection or upon
resolution of broken wire failure.

A possible source for this occurence is a rapid change
on the input. Another possiblity would be an existing
output level of 5.6mA upon Start Measurements from
a PC.

Figure 11 gives another damping example where the
output has been driven upscale to 23.6mA. After
fi ve seconds the 63% output change is reached at

16.98mA.

Figure 11. Damping When Output Driven Upscale to 23.6mA

In this instance, detection of an open sensor or broken
wire could be a cause. An instrument malfunction or
Adc/EEPROM failure may also be suspect.

A typical damping situation would be described as a
step change in output which causes the output to go
from 5.6mA to 20mA. After fi ve seconds the output
reaches 14.58mA which equals 63% of the output
step change. This is graphed in Figure 10.

Figure 10. Typical Damping Scenario

Output if Measurement OFF

Choose “Zero Range” to read zero volts or mA at
output if measurement was off.

Choose “Stay Last” to read the last value held before
the measurement was off.
