INTRODUCTION

Overview

CoreSense™Communications is a breakthrough

innovation for 20 to 40 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.

Features

CoreSense Communications has the following key

features:

1. Motor temperature protection

2. Scroll high temperature protection

3. Missing phase protection

4. Reverse phase protection

5. Low control circuit voltage protection

6. Short cycling detection and alert

7. Communication to system controller through

RS485/Modbus

8. Storage of operational history, runtime information,

fault counters, etc.

9. Display of status, warning, and alert information

via LEDs

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.

Flashing red and green LEDs communicate Status,

Warning, and Alert codes to the service technician and

the master controller.

Application Usage

WARNING

CoreSense Communications modules are not

interchangeable with any other brand of motor

protection module that may have been previously

used with Copeland Scroll compressors.

CoreSense Communications modules are not intended

tobeusedaseldretrotsforothermotorprotection

modules that may have been previously used with

Copeland Scroll compressors. The motor and scroll

thermistor circuits are configured differently for

Copeland Scroll with CoreSense Communications and

are not compatible with motor protection modules that

were previously used.

Copeland Scroll compressors equipped with CoreSense

Communications will have an “E” in the electrical code.

An example is the 40-ton scroll, ZP485KCE-TED.

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.

Agency Recognition

CoreSense Communications carries the following

agency recognitions:

INSTALLATION

Mounting

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.

WARNING

Always disconnect and lockout the power supply

before removing the compressor electrical box

cover for servicing.

Terminal Description and Basic Field Wiring

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:

T2-T1:Modulepowersupply,24or120/240VAC.

L1-L2-L3: Phase inputs corresponding to compressor

input power L1-L2-L3.

AE8-1384 R5

M2-M1: Normally open control circuit contacts; M2-

M1 should be wired in series with the compressor

contactor.

A (-), GND, B (+): RS485 communications.

Temperature Plug: See Figure 3foridenticationof

the PTC, NTC, and common connections.

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.

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.

Dielectric (Hipot) Testing

CAUTION

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

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ashingLED.Warningcodesdonot

result in a trip or lockout condition. Alert codes are

communicated via a red ashing LED. Alert codes

will result in a trip condition and possibly a lockout

condition.

Warning Codes (Green LED Flash Code)

Code 1 – Loss of Communication

Themodulewillash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 2 – Reserved For Future Use

Code 3 – Short Cycling

ThemodulewillashthegreenWarning LED three

times indicating the compressor has short cycled more

than48timesin24hours.Ashortcycleisdenedas

compressor runtime of less than 3 minutes. 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.

Code 4 – Open/Shorted Scroll Thermistor

ThemodulewillashthegreenWarning LED four

times indicating the scroll NTC thermistor has a

resistance value that indicates an open/shorted

thermistor (see Table 2). The Warning will be cleared

when the resistance value is in the normal range.

Alert/Lockout Codes (Red LED Flash Code)

Code 1 – Motor High Temperature

The module will ash the red Alert LED one time

indicating the motor PTC circuit has exceeded 4.5K

Ohms ± 25%. A code 1 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 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.

Code 2 – Open/Shorted Motor Thermistor

Themodulewill ash 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.

AE8-1384 R5

Once the module has locked out the compressor,

a power cycle or Modbus reset command will be

required to clear the lockout.

Code 3 – Short Cycling

Themodulewillash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

congured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.

Code 4 – Scroll High Temperature

ThemodulewillashtheredAlert LED four times

indicating the scroll NTC circuit is less than 2.4K

Ohms. A Code 4 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 scroll

NTC circuit is higher than 5.1K Ohms. The module

will lockout the compressor if the number of Code

4 Alerts exceeds the user congurable number of

Code 4 events within 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.

Code 5 – Reserved for Future Use

Code 6 – Missing Phase

The module will ash 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 M2-

M1 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ash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 M2-

M1 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.

Code 8 – Reserved For Future Use

Code9–ModuleLowVoltage

Themodulewillash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.

Please see Table 6 for a summary of Warning and Alert

codes and troubleshooting information.

Resetting Alert Codes

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.

Power Up Delay

When CoreSense Communications is cycled off, there

isathirteentofteenseconddelaybeforethemodule

is active.

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ashingLED.

COMMISSIONING

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:

1. Device ID Messages

2. CoreSense Status Messages

AE8-1384 R5

3. CoreSense History Status Messages

4. CongurationMessages

5. Command Messages

6. Firmware Update Messages

CoreSense status, conguration, 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.

For more information on CoreSense™Communications

features and to request Modbus maps please contact

your Application Engineer.

DIP Switch Conguration

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.

NOTICE

The module must be reset after changing any of

the DIP switch settings for changes to take effect.

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

control check to verify communications capability of the

module before it leaves the compressor manufacturing

plant. Switch 9 is also turned “on” for TE* motor code. All

other DIP switch default settings are in the “off” position.

NOTICE

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

signicant bit (LSB) and switch 5 is the most

signicant 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).

2. Switch6denes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.

3. Switch 7 denes 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.

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.

5. Switch9denesthethermistorconguration.If

the compressor has a voltage code of TE*, the

compressor has PTC and NTC thermistors for

motor and scroll temperature protection. If the

compressor voltage code is TW*, the compressor

has only PTC thermistors for motor and scroll

temperature protection. The default setting is “on”

for PTC and NTC thermistor types.

6. Switch 10 enables short cycling protection if

turned “on”. The default setting is “off”.

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

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

PC Interface Software

PC interface software is available from Emerson Climate

Technologies, Inc. The PC interface software allows

the design engineer access to status, conguration,

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.

AE8-1384 R5

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.

For more information on the PC interface software, how

to obtain it, and a tutorial on its use, please contact your

Application Engineer.

SERVICE

Field 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 with TE* motor codes.

NOTICE

If a compressor with CoreSense Communications

fails in the eld, 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.

Troubleshooting

WARNING

Always disconnect and lockout the power supply

before removing the compressor electrical box

cover for servicing.

For troubleshooting purposes the scroll and motor

thermistor circuits are similar to those of other Copeland

Scrolls with one exception, the scroll thermistor is a

negativetemperaturecoefcient(NTC)typethermistor.

This means that as the discharge temperature

increases, the resistance of the thermistor decreases.

The motor has positive temperature coefficient

(PTC) type thermistors; as the motor temperature

increases, so does the resistance of the thermistor

chain. To measure the resistance of the PTC and NTC

circuits 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 trouble shooting causes of high motor

and scroll temperatures please refer to the application

engineering bulletin for the compressor.

A loss of communications with the master controller for

morethanveminutesiscommunicatedviaagreen

ash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
