Figure 3.33 Suction Group Setup Screen

The E2 will default to a (Board / Point) application.

Before proofing can be programmed the E2 must be

changed to accept a (Controller / Application / Output)

format by following these steps:

1. With the cell next to CMP RUN PROOF highlight-

ed, press F3 (Edit).

2. Press 1 to select Alternate I/O Formats.

3. Press 2 to select Controller / Application /

Property.

4. Input the appropriate Controller / Application /

Property using F4 (Lookup).

Once the proofing associations have been made, the

suction group setup screen should look like figure

3.34 below:

4. Compressor Status Codes

The LED on the Intelligent Store™ Discus® front box

is designed to provide a rapid assessment of the

compressor’s operation condition. The LED codes

also provide some basic diagnostics to aid

troubleshooting of the system or compressor.

• Steady Code (not flashing): An indication of nor-

mal operation. There are no faults or issues with

the compressor.

• Flashing Code (a continuously flashing status

code): Refer to the status code table for interpre-

tation of the fault.

• Flashing of Random Symbols: Occurs for 30 sec-

onds after module power has been turned on. Also

occurs after “Reset” button is pushed. The

sequence of numbers will be an “8” followed by

the node and subnet address for the compressor.

This is normal, and is not an indication of fault.

4.0 Definitions

• Trip: The module has shut off the compressor due

to the fault condition. The compressor will be

available to run when the fault condition no longer

exists, and the minimum off time has been satis-

fied. The reset button does not need to be pushed

to clear a “Trip.” Pushing the reset button will not

clear the trip if the fault condition still exists.

• Lockout: The module has shut off the compressor

due to a fault condition. The compressor will NOT

be available to run when the fault condition has

been cleared until the reset button has been

pushed, or a remote reset has been activated.

4.1 Status Code Descriptions

Here is a brief description of each code that the

Intelligent Store™ Discus® can display, and what the

specific code means.

Description

0 Normal - Off. The contactor is de-ener-

gized, and the rack controller has not

called for the compressor to run.

1 Normal - Running. The rack controller has

called for the compressor to run, and the
