INTRODUCTION
Copeland Scroll compressors equipped with CoreSense
Communications will have an “E” in the electrical code.
An example is the 15-ton scroll, ZP182KCE-TED.
Overview
CoreSense ™ Communications is a breakthrough
innovation for 13 to 15 ton Copeland Scroll ™
air conditioning compressors. The CoreSense
Communications module, installed in the compressor
electrical box, provides advanced diagnostics,
protection, and communications that enhance
compressor performance and reliability.
Module Part Numbers
OEM and service compressors will have the CoreSense
Communications module installed in the compressor
electrical box. Individually packaged modules are
available to the aftermarket for component replacement.
Part numbers for OEM and service applications are
listed in Table 1 at the end of this bulletin.
Features
CoreSense Communications has the following key
features:
1. Motor temperature protection
Agency Recognition
CoreSense Communications carries the following
agency recognitions:
2. Missing phase protection
U.L. file E253322, Volume 7, Software Class B
3. Reverse phase protection
CB Test Certificate
4. Low control circuit voltage protection
Product Specifications
5. Short cycling detection and alert
CoreSense specifications are shown in Table 2. Many of
the electrical specifcations are the same as previously
used electronic motor protection modules.
6. Communication to system controller through
RS485/Modbus
7. Storage of operational history, runtime information,
fault counters, etc.
INSTALLATION
Mounting
8. Display of status, warning, and alert information
via LEDs
As mentioned above, CoreSense Communications will
be shipped already installed in the compressor electrical
box. Two holding tabs secure the module in the box.
To remove the module depress the holding tabs and
remove the module.
CoreSense Communications provides compressor
and system protection through its proprietary lockout
feature. Depending on the severity and frequency of
the fault that caused the trip condition, the CoreSense
Communications module can lockout the compressor
contactor to prevent damage to the compressor and
system components. Less severe fault conditions
resulting in an occasional trip will not result in a lockout
condition.
WARNING
Always disconnect and lockout the power supply
before removing the compressor electrical box
cover for servicing.
Terminal Description and Basic Field Wiring
Flashing red and green LEDs communicate Status,
Warning, and Alert codes to the service technician and
the master controller.
Figure 2 at the end of this bulletin shows the CoreSense
Communications module. Figures 1a and 1b are the
terminal box wiring diagrams. An explanation of the
terminal designations follows:
Application Usage
WARNING
T2-T1: Module power supply, 24 or 120/240 VAC.
CoreSense Communications modules may only be
used to retrofit Kriwan INT69 SU2 modules. They are
not interchangeable with any other brand of motor
protection module that may have been previously
used with Copeland Scroll compressors.
L1-L2-L3: Phase inputs corresponding to compressor
input power L1-L2-L3.
M2-M1: Normally open control circuit contacts; M2M1 should be wired in series with the compressor
contactor.
CoreSense Communications modules are only intended
to be used as field retrofits for Kriwan INT69 SU2 motor
protection modules that have been previously used with
13 to 15 ton Copeland Scroll compressors.
A (-), GND, B (+): RS485 communications.
© 2014 Emerson Climate Technologies, Inc.
Temperature Plug: See Figure 3 for identification of
the PTC and common connections.
4
AE8-1408 R1
When multiple CoreSense Communications modules
are networked, a shielded, twisted pair cable such
as Beldon #8761 (22 AWG) should be used for the
communication wiring.
Code 3 – Short Cycling
The module will flash the green Warning LED three
times indicating the compressor has short cycled more
than 48 times in 24 hours. A short cycle is defined
as compressor runtime of less than 1 minute. The
Warning will be activated when the “Short Cycling”
dipswitch (#10) is "off" or in the "down" position. When
fewer than 48 short cycles are accumulated in 24
hours the Warning code will be cleared.
NOTICE
The RS485 is polarity sensitive. When “daisy
chaining” modules the A (-) must connect to other
A (-) terminals and B (+) must connect to other B
(+) terminals.
Code 4 – Not used with this compressor family
Dielectric (Hipot) Testing
Alert/Lockout Codes (Red LED Flash Code)
CAUTION
Code 1 – Motor High Temperature
The module will flash the red Alert LED one time
indicating the motor PTC circuit has exceeded 4.5K
Ohms. A code 1 Alert will open the M2-M1 contacts.
The Alert will reset after 30 minutes and the M2M1 contacts will close if the resistance of the motor
PTC circuit is below 2.75K Ohms. Five consecutive
Code 1 Alerts will lockout the compressor. Once the
module has locked out the compressor, a power cycle
or Modbus reset command will be required for the
lockout to be cleared.
Use caution with high voltage and never hipot
when compressor is in a vacuum.
U.L. sets the requirement for dielectric strength testing
and should be consulted for the appropriate voltage
and leakage values. Emerson Climate Technologies
does not recommend hipot testing at voltages higher
than 1,000 VAC.
OPERATION
WARNING
Code 2 – Open/Shorted Motor Thermistor
The module will flash the red Alert LED two times
indicating the motor PTC thermistor circuit has a
resistance value that indicates an open/shorted
thermistor chain (see Table 2). A Code 2 Alert will
open the M2-M1 contacts. The Alert will reset after
30 minutes and the M2-M1 contacts will close if the
resistance of the motor PTC circuit is back in the
normal range. The module will lockout the compressor
if the trip condition exists for longer than 6 hours.
Once the module has locked out the compressor,
a power cycle or Modbus reset command will be
required to clear the lockout.
The CoreSense Communications module is a
recognized safety device and must be used with
all compressors that have TE* electrical codes.
A solid green LED indicates the module is powered and
operation is normal. A solid red LED indicates an internal
problem with the module. See the Troubleshooting
section of this bulletin for more information on what to
do if the red LED is solid.
CoreSense Communications communicates Warning
codes via a green flashing LED. Warning codes do not
result in a trip or lockout condition. Alert codes are
communicated via a red flashing LED. Alert codes
will result in a trip condition and possibly a lockout
condition.
Code 3 – Short Cycling
The module will flash the red Alert LED three times
indicating the compressor is locked out due to short
cycling. A Code 3 Alert will open the M2-M1 contacts.
Code 3 will be enabled when the "Short Cycling"
dipswitch (#10) is "on" or in the "up" position and the
compressor has exceeded the number of short cycles
configured by the user in a 24 hour period. Once the
module has locked out the compressor, a power cycle
or Modbus reset command will be required to clear
the lockout.
Warning Codes (Green LED Flash Code)
Code 1 – Loss of Communication
The module will flash the green Warning LED one
time indicating the module has not communicated
with the master controller for longer than 5 minutes.
Once communication is reinitiated, the Warning will
be cleared.
Code 4 – Not used with this compressor family
Code 2 – Reserved For Future Use

COMMISSIONING
Code 6 – Missing Phase
Communications
Programming knowledge and a familiarity with
Modbus will be required by the system designer
to use the communications features of CoreSense
Communications. CoreSense Communications
has opto-isolated RS485 for the physical layer. The
communication protocol is Standard Modbus and
Emerson Climate Technologies Modbus. CoreSense
Communications will act as the Modbus slave, while
the master will be implemented in a system controller,
PC software, or any other equivalent external device.
Use of the communications feature of CoreSense
Communications allows the master access to much of
the data that resides in the CoreSense Communications
module. Emerson Climate Technologies Modbus has
six message categories:
The module will flash the red Alert LED six times
indicating a missing phase in one of the three leads
to the compressor. A Code 6 Alert will open the M2M1 contacts. The Alert will reset after 5 minutes and
the M2-M1 contacts will close if the missing phase
condition is not present. The module will lockout the
compressor after 10 consecutive Code 6 Alerts.
Once the module has locked out the compressor,
a power cycle or Modbus reset command will be
required to clear the lockout.
Code 7 – Reverse Phase
The module will flash the red Alert LED seven times
indicating a reverse phase in two of the three leads
to the compressor. A Code 7 Alert will open the M2M1 contacts. The module will lockout the compressor
after one Code 7 Alert. A power cycle or Modbus
reset command will be required to clear the lockout.
1. Device ID Messages
2. CoreSense Status Messages
3. CoreSense History Status Messages
Code 8 – Reserved For Future Use
4. Configuration Messages
Code 9 – Module Low Voltage
5. Command Messages
6. Firmware Update Messages
The module will flash the red Alert LED nine times
indicating low module voltage (see Table 2) on the
T2-T1 terminals for more than 5 seconds. A Code 9
Alert will open the M2-M1 contacts. The Alert will reset
after 5 minutes and the M2-M1 contacts will close if
the T2-T1 voltage is above the reset value in Table 2.
CoreSense status, configuration, history, and device
information messages available to the master include
those listed in Table 4.
The history status messages give the order in which the
Warning/Alert has happened, with the total compressor
run time. Information about the Warning/Alert
occurrence during the last 7 days and the cumulative
Warning/Alert counter are also available.
Please see Table 6 for a summary of Warning and Alert
codes and troubleshooting information.
Resetting Alert Codes
For more information on CoreSense™ Communications
features and to request Modbus maps please contact
your Application Engineer.
Resetting Alert codes can be accomplished in two
different ways. First, Alert codes can be reset manually
by cycling power to the module (disconnect T2 or T1
for 5 seconds). The second way to reset Alert codes
is to send a Modbus reset command from the master
controller.
DIP Switch Configuration
DIP switch selection for the Modbus address, baud rate,
parity, and other operating conditions simplify service
and start-up procedures. Table 5 lists the purpose of
each switch.
Power Up Delay
When CoreSense Communications is cycled off, there
is a thirteen to fifteen second delay before the module
is active.
NOTICE
The module must be reset after changing any of
the DIP switch settings for changes to take effect.
If the fault that initiated the Alert code is absent after
one of the above resets is performed, the Alert code will
be cleared and CoreSense will allow normal operation.
If the fault is still present after the reset is performed the
fault code will continue to be displayed via the green
or red flashing LED.

CoreSense Communications modules are shipped from
the factory with the DIP switches set to default settings
for standalone operation. Default settings are shown
in Table 5. Switch 1 is turned “on” as part of a quality
6
AE8-1408 R1
control check to verify communications capability of the
module before it leaves the compressor manufacturing
plant. All other DIP switch default settings are in the
“off” position.
the modules on the ends of the daisy chain. All other
jumpers in the sequence of daisy chained modules
should be removed. The jumper can be removed using
miniature electronics needle nose pliers
NOTICE
PC Interface Software
PC interface software is available from Emerson Climate
Technologies, Inc. The PC interface software allows
the design engineer access to status, configuration,
history, and data logging via a computer. This method of
connecting and communicating with CoreSense is very
helpful during the unit development stage if CoreSense
is in stand-alone mode and not communicating with a
master controller.
If DIP switch settings are inadvertently changed,
the compressor will operate, but could have some
loss of protection. Scroll temperature protection
and short cycle protection could be disabled.
The following steps cover the DIP switch settings
throughout the commissioning process for a multiple
compressor system with communications.
1. Switches 1 through 5 are used for setting
the device address. DIP switch 1 is the least
significant bit (LSB) and switch 5 is the most
significant bit (MSB). DIP switch addresses
0 through 31 are shown in Figure 4. Each
CoreSense Communications module that is daisy
chained and connected to a master controller
must have a unique node address (as determined
by the DIP switch settings).
The RS-485/USB adapter used to connect the laptop
to the CoreSense is B & B Electronics model number
USOPTL4. Figure 5 illustrates the wiring and DIP switch
settings necessary to enable communications.
2. Switch 6 defines the communication baud rate for
the CoreSense Communications module. If the
switch is “off”, the baud rate is 19200. If the switch
is “on” the baud rate is 9600. The baud rate of
each CoreSense Communications module should
be set to match the master controller baud rate.
Field Service
For more information on the PC interface software, how
to obtain it, and a tutorial on its use, please contact your
Application Engineer.
SERVICE
Service compressors will be shipped with the CoreSense
Communications module installed in the compressor
terminal box. Special attention should be given to the
module DIP switch settings of the compressor being
replaced so the DIP switch settings can be transferred
to the module of the replacement compressor. As
mentioned earlier, the CoreSense Communications
module is a recognized safety device and shall be used
only with approved compressors.
3. Switch 7 defines the communications parity.
The default parity setting for the CoreSense
Communications module is no parity. If the switch
is set to “on” the module will communicate using
even parity. The parity setting must match the
parity setting of the master controller.
NOTICE
4. Switch 8 defines the control mode. The
default setting is standalone mode (off). If
communications with a master controller is
desired, switch 8 should be turned “on” to
network.
If a compressor with CoreSense Communications
fails in the field, the CoreSense module should
remain with the failed compressor so Emerson
technicians can download the CoreSense data
to assist with determining the root cause of
compressor failure.
5. Switch 9 defines the thermistor configuration. The
default setting is “off” for PTC thermistor types.
Troubleshooting
6. Switch 10 enables short cycling protection if
turned “on”. The default setting is “off”.
WARNING
Always disconnect and lockout the power supply
before removing the compressor electrical box
cover for servicing.
Jumper Setting
CoreSense Communications modules are shipped
with the jumper installed. For standalone operation
the jumper should remain installed. For daisy chained
applications the jumper should remain installed for

For troubleshooting purposes the motor thermistor
circuits are similar to those of other Copeland Scrolls.
The motor has positive temperature coefficient (PTC)
7
AE8-1408 R1
type thermistors; as the motor temperature increases,
so does the resistance of the thermistor chain. To
measure the resistance of the PTC circuit simply
remove the temperature plug from the CoreSense
module and measure the resistance in the appropriate
pins shown in Figure 3. The measured values should
be in the ranges listed in Table 2. For information on
troubleshooting causes of high motor temperatures
please refer to the Application Engineering Bulletin for
the compressor.
A loss of communications with the master controller for
more than five minutes is communicated via a green
flash code 1 if DIP switch #8 is enabled. CoreSense
Communications has no provisions to detect incorrect
wiring neither between daisy chained modules nor to
the master controller. Ideally, the master controller will
contain advanced troubleshooting menus for help in
diagnosing communications issues between the master
controller and the CoreSense module.
NOTICE
In some rare cases communication between the
master controller and the CoreSense module is
problematic. Reversing the polarity will re-initiate
communication.
To reverse polarity:
1. Adjust CoreSense to negative
2. Adjust master controller to positive
