5.6 Replacement Module Information

5.6.1 Determine the Replacement Module

Part Number

When ordering a replacement module (front box) the

address (node number) is required. The replacement

part number reflects the node number that is pre-pro-

grammed into the module. There are several screens

on the E2 that display the node number of the

compressor. An example is the online status screen:

1. Press menu to open the Main Menu.

2. Press 7 (System Configuration).

3. Press 7 (Network Setup).

4. Press 1 (Online Status).

The replacement part number reflects the node

number. An easy way to verify that the node number

is correct is to see that the status is “off line” when

the module is not powered up, or has been

removed in the service process.

The module P/N will be 985-0102-xx, where “xx” is the

node number.

Example:

Node number 3: order 985-0102-03

Node number 11: order 985-0102-11

Note: To avoid paying a core charge, return the

failed module to your Authorized Emerson® Full-

Line or Authorized Copeland® Wholesaler when

taking delivery of the new module.

5.6.2 Power-Up Instructions for the New

Module

1. Complete the mechanical installation procedures

for installation of the module (section 5.3 for 2D /

3D, section 5.4.2 for 4D). Always turn off com-

pressor power before working with the module

and its associated wiring harness.

2. After making all harness connections (including

plugging in the communication line), move the

blue communication board jumpers to the proper

position. If the compressor is at the end of the

communication line daisy-chain, the jumpers are

positioned to “terminated”. If the compressor is in

the middle of the daisy-chain, the jumpers are

positioned to “unterminated”. Refer to figure 2.1

for a diagram explaining the jumper positions.

3. Turn on power to the module. A module that has

been installed on a 2D or 3D compressor will typ-

ically display a flashing “7” code until step 4 below

has been completed.

. After verifying that communication has been

established with the new module (observe that the

decimal point blinks at least once), reboot the E2.

This can be accomplished by temporarily turning

the E2 power off, and after 10 seconds turning it

back on. It is important that the module power

remain ON for this process. The E2 will download

all of the configuration settings from the previous

module into the new module. This may take sev-

eral minutes. All compressors on the rack may

momentarily shut off for a few seconds as the E2

reboots.

5.7 Event Counters - Service Procedures

Updating the Event Counters

The E2 cannot clear or re-zero the “Event Counters”

in the module. This means that if a compressor or

module is replaced, the Event Counters reflected in

the E2 will not be correct. We recommend that the

user use the Notepad feature of the E2 to indicate the

change in the Event Counters of the module when
