DESCRIPTION
Series 801T Transmitters and combination Transmitter/
Alarms are members of the popular Acromag IntelliPack
transmitter & alarm family. These models will condition DC
voltage, thermocouple, or RTD inputs. The transmitter output is
an isolated process current or voltage, plus an optional Single-
Pole Double-Throw (SPDT) electro-mechanical alarm relay
(Model 801T-1500). All IntelliPacks contain an advanced
technology microcontroller with integrated downloadable flash
memory and EEPROM for non-volatile program, configuration,
calibration, and parameter data storage. Units are fully
reconfigurable via our user-friendly Windows 95or NT
IntelliPack Configuration Program. Field reconfigurability is also
possible with module push-buttons and status LED’s. Once
configured, these modules may operate independent of the host
computer for true embedded monitoring and control.
Each module provides a single input for either DC millivolts,
thermocouple, or RTD signals. RTD sensor excitation,
linearization, lead-wire compensation, and lead break detection
are included. Thermocouple reference-junction compensation,
linearization, and open circuit or TC break detection is also
provided. Model 801T Transmitters provide an isolated process
current or voltage output and Model 801T-1500 units include an
isolated alarm relay. The relay has a yellow LED on the front of
the module that provides a visual indication of the high or low
alarm condition. Additionally, green “Run”, yellow “Status”, and
“Zero/Full-Scale” LED’s provide local feedback of operating
mode, system diagnostics, and field configuration status.

Front panel push buttons are available to reset a latched alarm
and to facilitate field configuration without connecting to a host
computer.
The module uses a high resolution, low noise, Sigma-Delta,
Analog to Digital Converter (-ADC) to accurately convert the
input signal into a digitized value. An optically isolated Digital-to-
Analog Converter (DAC) provides the corresponding process
current or voltage output. A separate alarm circuit controls the
relay contacts.
Flexible transmitter functionality and an optional alarm
combined in a single device, plus convenient reprogrammability,
makes this instrument extremely powerful and useful over a
broad range of applications. This transmitter may be configured
for several input transfer functions (with millivolt input), such as,
proportional, 24-segment linearizer, and square root. Input
averaging may also be combined with any function. The output
may produce a normal (ascending), or reverse (descending)
response. The optional relay of 801T-1500 models may be
configured as a limit alarm with deadband, with latching or non-
latching contacts, and for failsafe or non-failsafe modes. A
programmed relay time delay may be implemented to filter
transients and minimize nuisance alarms.
All IntelliPack modules are designed to withstand harsh
industrial environments. They feature RFI, EMI, ESD, EFT, and
surge protection, plus low temperature drift, wide ambient
temperature operation, and isolation between input, power,
output, and relay contacts. They also have low radiated
emissions per CE requirements. As a wide-range DC-powered
device, the unit may be powered from DC power networks
incorporating battery backup. Additionally, the input power
terminal is diode-coupled, providing reverse polarity protection.
This allows the unit to be connected to redundant power supplies,
or several units to safely share a single DC supply.
Units are DIN-rail mounted and removable terminal blocks
facilitate ease of installation and replacement, without having to
remove wiring. Transmitter power, output, and relay wiring are
inserted at one side of the unit, while input wiring is inserted at
the other side. Connectors are an industry standard screw clamp
type and accept a wide range of wire sizes.
The safe, compact, rugged, reconfigurable, and reliable
design of this transmitter makes it an ideal choice for control
room and field applications. Custom IntelliPack module
configurations are also possible (please consult the factory).

Your application may differ from the default configuration and
will require that the transmitter be reconfigured to suit your needs.
This is accomplished with Acromag’s user-friendly Windows 95
or NTConfiguration Program and Serial Port Adapter.
Configuration is normally done prior to field installation since field
configurability via the module’s push-buttons is generally limited
to zero, full-scale, setpoint, and dropout adjustments. See the
Transmitter Configuration Manual (8500-570) for instructions.
Jumper Installation (For Voltage Output Only)
For voltage output, a short jumper must be installed between
the output “I+” and “JMP” terminals. A jumper wire has been
included with the unit and is already installed between the “JMP”
and I+ terminals. Verify jumper installation if your application
requires output voltage. Remove this jumper for current output
applications. Refer to the Electrical Connections Drawing
4501-681.
Mounting: Refer to Enclosure Dimensions Drawing 4501-642 for
mounting and clearance dimensions.
DIN Rail Mounting: This module can be mounted on "T"
type DIN rails. Use suitable fastening hardware to secure the
DIN rail to the mounting surface. Units may be mounted
side-by-side on 1-inch centers for limited space applications.
"T" Rail (35mm), Type EN50022: To attach a module to this
style of DIN rail, angle the top of the unit towards the rail and
locate the top groove of the adapter over the upper lip of the
rail. Firmly push the unit towards the rail until it snaps solidly
into place. To remove a module, first separate the input
terminal block(s) from the bottom side of the module to
create a clearance to the DIN mounting area. Next, insert a
screwdriver into the lower arm of the DIN rail connector and
use it as a lever to force the connector down until the unit
disengages from the rail.
Electrical Connections
Output, power, and relay terminals can accommodate wire
from 12-24 AWG, stranded or solid copper. Strip back wire
insulation 1/4-inch on each lead before installing into the terminal
block. Input wiring should be shielded twisted-pair. Since
common mode voltages can exist on signal wiring, adequate wire
insulation should be used and proper wiring practices followed. It
is recommended that transmitter output and power wiring be
separated from the input signal wiring for safety, as well as for
low noise pickup. Note that input, power, output, and relay
terminal blocks are a plug-in type and can be easily removed to
facilitate module removal or replacement without removing
individual wires. If your application requires voltage output, you
must install a jumper between the output “I+” and “JMP”
terminals. This jumper is installed at the factory and should be
removed for current output applications. Be sure to remove
power and/or disable the load before unplugging the terminals to
uninstall the module, installing or removing jumpers, or before
attempting service. All connections must be made with power
removed.
CAUTION: Risk of Electric Shock - More than one
disconnect switch may be required to de-energize the
equipment before servicing.
1. Power: Refer to Electrical Connections Drawing 4501-681.
Variations in power supply voltage within rated limits has
negligible effect on module accuracy. For supply
connections, use No. 14 AWG wires rated for at least 75C.
The power terminal is diode-coupled for reverse polarity
protection.
2. Input: Connect input per Electrical Connections Drawing
4501-681. Observe proper polarity when making connections
(see label for input type).
3. Analog Output Connections: Wire outputs as shown in
Electrical Connections Drawing 4501-681. For voltage
output, you must also install a jumper between the output “I+”
and “JMP” terminals (installed at the factory). Remove this
jumper for current output.
Note: For sensitive applications, high frequency noise may
be reduced by placing a 0.1uF capacitor directly across the
load.
4. Output Relay Contacts: Wire relay contacts as shown in
Electrical Connections Drawing 4501-681. See the “Alarm
Relay Specifications” for power capacity. If necessary, an
interposing relay can be used to switch higher currents as
shown in Interposing Relay Connection Drawing 4501-646.
Electromechanical Relay Contact Protection: To
maximize relay life with inductive loads, external protection is
required. For DC inductive loads, place a diode across the
load (1N4006 or equivalent) with cathode to (+) and anode to
(-). For AC inductive loads, place a Metal Oxide Varistor
(MOV) across the load. See Relay Contact Protection
Drawing 4501-646 for details.
IMPORTANT: Noise and/or jitter on the input signal has the
effect of reducing (narrowing) the instrument’s deadband and
may produce contact chatter. The long term effect of this will
reduce the life of mechanical relays. To reduce this
undesired effect, you should increase the effective deadband.
Note that the input averaging function of this transmitter may
also be used to reduce contact chatter.
5. Grounding: See Electrical Connections Drawing 4501-681.
The module housing is plastic and does not require an earth
ground connection. However, there are mounting positions
on the output terminals to connect a cable shield, plus earth
ground. These connections are isolated from the internal
circuit and are recommended to minimize noise and help
protect the unit from damaging I/O transients.
WARNING: For compliance to applicable safety and
performance standards, the use of shielded cable is
recommended as shown in Drawing 4501-681. Further, the
application of earth ground must be in place as shown in
Drawing 4501-681. Failure to adhere to sound wiring and
grounding practices may compromise safety & performance.

3.0 MODULE CONFIGURATION
This transmitter/alarm module needs to be configured for
your application. Configuration is done using Acromag’s
Windows 95or NTIntelliPack Configuration Program and
Serial Port Adapter. Transmitter calibration and configuration
details are included in the IntelliPack Transmitter Configuration
Manual (8500-570). Field calibration of transmitter zero, full-
scale/span, setpoint, and dropout/deadband via the module’s
push-buttons and LED’s is covered in the following paragraphs.
FIELD CALIBRATION/CONFIGURATION
This program mode allows adjustment to key transmitter
calibration and alarm parameters in the field, without having to
connect a host computer. Field reprogrammability of zero & full-
scale (input to output scaling), plus alarm setpoint & deadband
(Model 801T-1500) is alternately accomplished via the
transmitter/alarm module’s “SET”, “MODE”, “UP”, and “DOWN”
push buttons, and the zero/full-scale and relay LED’s (see
Drawing 4501-642).
Equipment Required
An accurate input source (voltage or resistance) adjustable
over the range required for alarm setpoint and dropout. A
thermocouple (or mV source with an ice-point reference) or RTD
calibrator may also be used. Note: For best results, the input
source must be accurate beyond the required specifications. For
voltage inputs, use a voltage source with an output impedance of
100or less. An accurate current or voltage meter is also
required to monitor the output level. This meter must be accurate
beyond the module specifications for best results.
Note: The module’s input range must already be set via the
IntelliPack Configuration Software. Input levels outside of the
configured input range will not be accepted for zero, full-scale,
setpoint, or dropout calibration. Since input levels cannot be
validated during field programming, entering incorrect signals can
produce an undesired output response. Install a jumper between
the output “I+” and “JMP” terminals for voltage output, remove
this jumper for current output.
Transmitter/Alarm General Field Programming Procedure
The following procedure uses the corresponding zero/full-
scale (labeled “Z/FS”) and relay (labeled “RLY”) LED’s to indicate
which parameter is being programmed. A constant ON zero/full-
scale LED refers to zero configuration (scaling input for 0%
output), a flashing ON/OFF zero/full-scale LED refers to full-
scale/span configuration (scaling input for 100% output). A
constant ON relay LED indicates setpoint adjustment, a flashing
ON/OFF relay LED indicates dropout/deadband adjustment.
Refer to Table 3.

CAUTION: Do not insert sharp or oversized objects into the
switch openings as this may damage the unit. When depressing
the push-buttons, use a blunt tipped object and apply pressure
gradually until you feel or hear the tactile response.
Note: The transmitter’s input type, temperature units, sensor
break direction, CJC on/off (TC models), input wiring (RTD
models), and output range can only be set via the IntelliPack
Configuration Program. For example, use the software to select
a Type J thermocouple, degrees Celsius units, CJC ON, a normal
acting 4 to 20mA output. You may use field program mode to
scale virtually any part of the input range to the selected output
range via the front panel push buttons. For example, use the 0 to
200C portion of the type J TC input to drive the 4 to 20mA output
range--this configuration will be used as an example range in the
following procedure.
IMPORTANT: You must allow the unit to warm-up, powered and
oriented as in its final application, for at least 5 minutes prior to
calibrating the unit. Failure to warm the unit prior to calibration
may result in measurement error.
1. Connect a precise voltage source; thermocouple calibrator,
or RTD calibrator to the input, as required (refer to Electrical
Connections Drawing 4501-681). Also, according to the
module’s output configuration, connect a precise current or
volt meter to read the transmitter’s output signal.
2. Apply power and the module’s green “Run” LED will light.
3. Press and hold the “MODE” push button until the green
“Run” LED turns OFF and the yellow “Zero/Full-Scale” LED
turns ON. In this mode, the unit is ready to accept a zero
input for the transmitter (equivalent to the scaling input for
0% output). If you do not wish to change the zero
parameter, skip to step 7.
4. Adjust the input source to the zero value (this value must be
within the input range selected). For our example: use 0C.
5. Press the “UP” or “DOWN” push-button once. Refer to
Functional Block Diagram 4501-689 and note that internally,
the output of the Range Adjust Box is now set for 0.0% for
the input zero value of 0C. The transmitter will adjust it’s
output to the minimum output value (4.000mA). If the
measured output is not exactly at the zero level (4.000mA),
press the UP or DN switches continuously until the desired
output is achieved.
Note: After first pressing the UP & DN push-buttons, they
will function as trim adjustments for the output stage. The
output trim adjustment should be limited to 10%. Each
successive depression of the “UP” or “DN” switch will
increment or decrement the output signal by a small
amount. Holding the switch depressed will increase the
amount of increment or decrement.
6. Press the “SET” push-button to accept the zero value.
Note that every time “SET” is pressed, the yellow “Status”
LED will flash once and the zero output will be captured.
7. Press the “MODE” push button one time. The yellow
“Zero/Full-Scale” LED will flash on/off, indicating that the unit
is ready to accept the full-scale value (equivalent to the
scaling input for 100% output). If you do not wish to change
this parameter, skip to step 11.
8. Adjust the input source to the full-scale value (the input
value must be within the input range selected). For
example: 200C. Note: The full-scale value must be
greater than the zero value. If the zero and full-scale points
are too close together, performance will be degraded.

9. Press the “UP” or “DOWN” push-button once. Refer to
Functional Block Diagram 4501-689 and note that internally,
the output of the Range Adjust Box is now set for 100.0% for
the input full-scale value of 200C. The transmitter will
adjust it’s output to the maximum output value (20.000mA).
If the output is not exactly at the full-scale level (20.000mA),
press the UP or DN switches continuously until the desired
output is achieved. Note: After first pressing the UP & DN
push-buttons, they will function as trim adjustments for the
output stage. The output trim adjustment should be limited
to 10%. Each successive depression of the “UP” or “DN”
switch will increment or decrement the output signal by a
small amount. Holding the switch depressed will increase
the amount of increment or decrement.
10. Press the “SET” push-button to accept the full-scale value.
Note that every time “SET” is pressed, the yellow “Status”
LED will flash once and the full-scale output will be captured.
11. If you are configuring an 801T-0500 model, which has no
alarm function, then you should skip steps 12-17 and jump
ahead to step 18.
12. Press the “MODE” push button one time until the yellow
zero/full-scale LED goes out and the yellow relay LED turns
ON (see Table 3). In this mode, the unit is ready to accept
an input setpoint level for the alarm. If you do not wish to
change the setpoint, skip to step 15.
Note: The setpoint can be set to any value within the input
range selected regardless of the zero/full-scale settings.
For example, you can have a setpoint of 300C with a
TC Type J transmitter calibrated for 0-200C as its nominal
range is from -200C to 760C.
13. Adjust the input source to the High or Low alarm setpoint
level.
14. Press the “SET” push button to accept the setpoint. Note
that every time the “SET” button is pressed, the yellow
status LED will flash once and the value at the input will be
captured.
15. Press the “MODE” push button one time and the yellow
relay LED should start flashing (see Table 3). This means
that the unit is ready to accept the dropout level for the
alarm relay. If you do not wish to change the dropout, skip
to step 18.
16. Adjust the input source to the desired dropout level.
17. Press the “SET” push button to accept the input dropout
level. Note that every time the “SET” button is pressed, the
yellow status LED will flash once and the value at the input
will be captured. The module will use the difference
between the setpoint and dropout values to calculate relative
deadband.
18. Press the “MODE” push button one time to complete the
program sequence and return to run mode. The green
“RUN” LED will turn ON, the yellow “Zero/Full-Scale” LED
will be OFF, and the yellow alarm LED will be on or off
according to the alarm status. The module will now assume
a transfer function based on the zero and full-scale values
just set. The setpoint and dropout of 801T-1500 units is
used to determine the alarm deadband. Note: If no push-
buttons are depressed for a period greater than 3 minutes,
then the module will automatically revert to run mode (green
“Run” LED will light) and no changes will be made to the
original zero, full-scale, and optional setpoint & dropout
settings.
4.0 THEORY OF OPERATION
Refer to Simplified Schematic 4501-680 and Functional Block
Diagram 4501-689 to gain a better understanding of the circuit.
Note that these transmitters will accept a thermocouple, an RTD
sensor, or a voltage input, and condition it to a voltage signal for
the A/D converter. The A/D converter stage then applies
appropriate gain to the signal, performs analog-to-digital
conversion, and digitally filters the signal. The digitized signal is
then transmitted serially to a microcontroller. The microcontroller
completes the transfer function according to the transmitter type
and its embedded function, and sends a corresponding output
signal to an optically isolated Digital-to-Analog Converter (DAC).
The DAC then updates its current or voltage outputs in response.
The microcontroller also compares the signal value to the limit
value according to the alarm type and completes all necessary
alarm functions per its embedded program (801T-1500 units
only). The embedded configuration and calibration parameters
are stored in non-volatile memory integrated within the micro-
controller. Only the functions required by an application are
actually stored in memory—new functionality can be downloaded
via the IntelliPack Configuration Program and Serial Port Adapter.
A wide input switching regulator (isolated flyback mode) provides
isolated +5V power to the circuit, plus an isolated +15V output
circuit supply. Refer to Functional Block Diagram 4501-689 for
an overview of how the software/push-button configuration
variables are arranged.
5.0 SERVICE AND REPAIR
CAUTION: Risk of Electric Shock - More than one
disconnect switch may be required to de-energize the
equipment before servicing.
SERVICE AND REPAIR ASSISTANCE
This module contains solid-state components and requires no
maintenance, except for periodic cleaning and transmitter
configuration parameter (zero, full-scale, setpoint, deadband, etc)
verification. Since Surface Mounted Technology (SMT) boards
are generally difficult to repair, it is highly recommended that a
non-functioning module be returned to Acromag for repair. The
board can be damaged unless special SMT repair and service
tools are used. Further, Acromag has automated test equipment
that thoroughly checks and calibrates the performance of each
module. Please refer to Acromag’s Service Policy Bulletin or
contact Acromag for complete details on how to obtain service
parts and repair.
PRELIMINARY SERVICE PROCEDURE
Before beginning repair, be sure that all installation and
configuration procedures have been followed. The unit routinely
performs internal diagnostics following power-up or reset. During
this period, all LED’s will turn ON momentarily, and the green
“Run” LED flashes. If the diagnostics complete successfully, the
“Run” LED will stop flashing after approximately one second and
remain ON. This indicates that the unit is operating normally. If
the “Run” LED continues to flash, then this is indicative of a
problem.

IntelliPack Series 801T Transmitter/Alarm User's Manual mV/TC/RTD Input
___________________________________________________________________________________________
- 8 -
In this case, use the Acromag IntelliPack Configuration Software
to reconfigure the module and this will usually cure the problem.
If the diagnostics continue to indicate a problem (a continuously
flashing green LED), or if other evidence points to a problem with
the unit, an effective and convenient fault diagnosis method is to
exchange the questionable module with a known good unit.
The IntelliPack Serial Port Adapter also contains a red LED
visible at the small opening in the enclosure to the right of the
RJ11 receptacle. If this LED is OFF or Flashing and power is
ON, then a communication interface problem exists. Note that
the adapter receives its power from the IntelliPack module. A
constant ON LED indicates a properly working and powered
serial interface adapter.
Acromag’s Application Engineers can provide further
technical assistance if required. When needed, complete repair
services are available from Acromag.

FIELD CONFIGURATION AND CONTROLS
Field programming of transmitter zero and full-scale (all
models), plus alarm setpoint and dropout levels (801T-1500
only), is accomplished with module push-buttons and LED
indicators. Note: The unit must first be configured using the
Configuration Software before its configuration can be changed in
the field.
Module Push Buttons (See Dwg. 4501-643 For Location):
Mode - Used to change mode of field configuration.
Set - Used to accept input data during field calibration.
Up (Reset) - Used to increment output level during field
calibration. Used to reset a latched alarm relay in
operating mode.
Down (Reset) - Used to decrement output level during field
calibration. Used to reset a latched alarm relay in
operating mode.
LED Indicators (Operating Mode):
Run (Green) - Constant ON indicates power is applied and
unit is operating normally. Flashing ON/OFF indicates
unit is performing diagnostics (first second following
power-up), or has failed diagnostics (after a few
seconds).
Status (Yellow) - Flashing ON/OFF indicates an open sensor
or that the input is outside of the selected input range. A
constant ON indicates the input is outside of the
transmitter’s calibrated input range.
Zero/Full-Scale (Yellow) - OFF in Run mode.
Relay (Yellow) - Constant ON indicates alarm condition for
relay. During field configuration, this LED has a different
function (see below).
LED Indicators (Field Configuration Mode):
Run (Green) - Turned OFF in this mode.
Status (Yellow) - Flashes each time the “SET” push button is
pressed to capture an I/O signal in this mode.
Zero/Full-Scale (Yellow) - ON or FLASHING in this mode if
zero or full-scale is being adjusted (See Table 3).
Relay (Yellow) - ON or FLASHING if alarm setpoint or
dropout is being adjusted (See Table 3) in this mode.
HOST COMPUTER COMMUNICATION
Host Communication Port (SPI): IntelliPack SPI port (standard
RJ11 6-wire phone jack). See Drawing 4501-643 for location.
Configuration information is downloaded from the host
computer through one of its EIA232 serial ports. This port
must be connected to the module through an Acromag
IntelliPack Serial Port Adapter. This Serial Port Adapter
serves as an isolated interface converter between EIA232
and the IntelliPack’s SPI port.
Baud Rate (EIA232): 19.2K baud.
SOFTWARE CONFIGURATION
Units are fully reprogrammable via our user-friendly Windows
95or NTIntelliPack Configuration Program (Model 5030-881).
A cable (5030-902) and converter (5030-913) are required to
complete the interface (Software Interface Package 800C-SIP).
See Drawing 4501-643.
The following transmitter and alarm attributes are selectable
via the IntelliPack Configuration Software. Refer to the
IntelliPack Transmitter Configuration Manual (8500-570) for a
more detailed explanation of these attributes and their
application.
Input Configuration
Input - Range: The transmitter can be configured to accept any
one of the input types described in the Input Specifications
using the IntelliPack Configuration Software.
Input - Temperature Units: Select C, F, or K units.
Input - RTD Wiring: The RTD wiring must be specified for
proper lead-wire compensation. Transmitter can be
configured for two, three, or four-wire (Kelvin or
compensation loop) RTD sensors.
Input - CJC (Cold Junction Compensation): Thermocouple
units only. Must be set to ON when directly connecting a
thermocouple to the module (default). The CJC can be set to
OFF when connecting a millivolt source, representing
temperature, directly to the module’s input terminals.
Input - Samples/Averaging: Samples can be set to 1 (default),
2, 4, 8, or 16, for calculation of an average value. The
number selected indicates the number of input signal A/D
conversions used in the average. Useful to help filter out
transients. The response time will be increased by the factor
selected. Both the alarm relay and transmitter output will use
the averaged value.
Input - Sensor Break: The detent for detection of a temperature
sensor failure (TC or RTD) can be set to upscale or
downscale.
Input Calibration: The configuration software can be used to
calibrate the input conditioning circuit of this module.
Analog Output Configuration
Output - Range: Unit can be configured for either a voltage or
current output range. A jumper must also be installed
between the output “I+” and “JMP” terminals for voltage
output (remove this jumper for current output).
Voltage: 0 to 10V DC, 0 to 5V DC
Current: 0 to 20mA DC, 4 to 20mA DC, or 0 to 1mA DC
Output - Mode: Select a normal acting (ascending), or reverse
acting (descending) output response.
Output Calibration: The configuration software can be used to
calibrate the output conditioning circuit of this module.
Transmitter Configuration
Transmitter - Scaling: Scaling is performed after averaging and
converts the engineering units of the input range (or a portion
of the input range) to 0 to 100% at the output. That is,
scaling allows virtually any part of the selected input range to
be scaled to 0% and 100% at the transmitter analog output.
The scaling may also be adjusted in-field via front panel
push-buttons and status LED’s.

Transmitter - Computation: The following gives a brief
description of current available transmitter transfer functions
that can be applied to this model via the Configuration
Software:
•None/Proportional (Default): Each input sample is
converted into a directly proportional output update.
•Square Root: Each input sample is converted into a
corresponding output update that is the square root of
the input signal. Output in percent is computed as the
square root of the product of input in percent and 100
percent.
•Linearizer: Permits the entry of 25 user-defined input-
to-output break points to facilitate up to 24-segment
linearization of a non-linear sensor signal.
Minimum Input Spans: See Table 6.
End Points Configuration: Transmitter: Zero/Full-Scale Input
maps to Zero/Full-Scale Output.
Alarm Configuration (801T-1500)
Model 801T-1500 units may be configured for simple limit alarms.
You may also refer to the IntelliPack 800A Alarm Family for
dedicated alarm modules that support other operating functions.
Alarm - Input: The input signal range to the alarm is the full
range for the configured input type, regardless of the calib-
rated range. For example: If a type J TC is selected using
the configuration program, the alarm can be programmed to
any setpoint from -200C to +760C. If input averaging is
used, an averaged input value will be used by the alarm.
Alarm - Mode: Select a High or Low limit for the alarm function
of this model. The relay will trip on an increasing input signal
for a high limit, and on a decreasing input for a low limit.
Alarm - Setpoint: A high or low setpoint (plus deadband) may
be assigned to the relay and is programmable over the entire
input range. The relay will enter the alarm state when either
the user-defined high or low setpoint is exceeded for the
specified amount of time (this allows input transients to be
filtered). Relay remains in the alarm state until the input
signal has retreated past the defined setpoint, plus any
deadband, for the specified amount of time. Please refer to
the IntelliPack alarm family for dedicated alarm modules that
support other operating functions.
Alarm - Deadband: Deadband is associated with the setpoint
and is programmable over the entire input range. Deadband
determines the amount the input signal has to return into the
“normal” operating range before the relay contacts will
transfer out of the “alarm” state. Deadband is normally used
to eliminate false trips or alarm “chatter” caused by
fluctuations in the input near the alarm point. Note that
deadband may also apply to latched alarms. If the alarm is
latching, it is recommended that the deadband be set to a
minimum.
IMPORTANT: Noise and/or jitter on the input signal has
the effect of reducing (narrowing) the instrument’s
deadband and may produce contact chatter. Another
long term effect of contact chatter is a reduction in the
life of the mechanical relay contacts. To reduce this
undesired effect, increase the deadband setting.
Visual Alarm Indicator: A yellow LED (labeled “RLY”) for the
relay provides visual status indication of when the relay is in
alarm (LED is ON in alarm). This LED is also used in field
configuration mode to indicate whether setpoint or deadband
is being adjusted.
Relay - Time Delay: Programmable from 0 milliseconds to 4
seconds in 200ms increments for this model (typically used
to help filter input transients and avoid nuisance alarming). A
minimum delay of 200ms is recommended for increased
noise immunity and conformance to applicable safety
standards. This delay does not apply to control of the
transmitter’s analog output.
Relay - Operating Mode: User configurable for “failsafe”
operation (relay deenergized in alarm state), or non-failsafe
operation (relay energized in alarm state). Failsafe mode
provides the same contact closure for alarm states as for
power loss, while non-failsafe mode uses alarm contact
closure opposite to power loss conditions.
Relay - Reset: The relay may be configured to automatically
reset when the input retreats past its setpoint and deadband,
or the relay may latch into its alarm state. Use the up or
down push-buttons on the front of the module to reset a
latched relay and exit the latched state (this may also be
accomplished under software control).
Other IntelliPack Configuration Software Capabilities
In addition to configuring all features of the module described
above, the IntelliPack Configuration Software includes additional
capabilities for testing and control of this module as follows:
•Monitors the input and output signal values and allows
polling to be turned on or off. Also monitors the reference
temperature of the CJC circuit.
•Allows a configuration to be uploaded or downloaded to/from
the module. Also provides a means to rewrite a module’s
firmware if the microcontroller is replaced or a module’s
functionality is updated.
•Provides controls to separately calibrate the input & output
stages, and the temperature reference. Also provides
controls to restore the original factory input, output, or
reference calibration in case of error.
•Provides controls to reset a module and reset a latched
alarm.
•Provides a control to adjust a transmitter’s output signal
independent of the input signal.
•Allows optional user documentation to be written to the
module. Documentation fields are provided for tag number,
comment, configured by, location, and identification
information. This information can also be uploaded from the
module and printed via this software.
•Allows a module’s complete configuration to be printed in an
easy to read, two-page format, including user
documentation.
For complete information on the IntelliPack Configuration
Software, refer to Transmitter Configuration Manual 8500-570.
