5.3.16 CUSTOM TEXT

This menu permits the user to set up a custom text message with a maximum length of 16 characters.

The message may use any of the following characters or a blank space:

ABCDEFGHIJKLMNOPQURSTUVWXYZ#%*-0123456789.

This custom text can be designated as the custom alarm text in the CUSTOM ALARMS menu (see

CUSTOM ALARMS above). To define the message:

1. Press the ENTER button to access the menu.

2. Use the up or down arrow key to change the character with the pointer below it.

3. Press the ENTER button to go to the next character.

4. Repeat the steps for all characters in the message (maximum of 16 characters).

5. Press the ENTER button to accept new custom text.

5.3.17 DIAGNOSTICS

This allows the user to perform checks on inputs, outputs, and conduct a test of the Liebert XDC con-

trol board from the wall box.

Entering the TEST OUTPUTS will interrupt system operation. Selecting TEST INPUTS or TEST

MICRO will not interrupt system operation. Pressing ENTER and selecting TEST OUTPUTS will

permit the user to toggle the following outputs on and off:

PUMP 1—On/Off

PUMP 2—On/Off

COMP 1A, 2A, 1B, 2B—On/Off

GREEN LAMP—On/Off

RED LAMP—On/Off

COMMON ALARM—On/Off

LLSV1, LLSV2—On/Off

HGSV1, HGSV2—On/Off

HGV1, HGV2—On/Off

DEHYDRATION1, DEHYDRATION2—On/Off

Pressing ENTER and selecting TEST INPUTS will permit the user to read the following inputs:

INPUT POWER—On/Off

CONDENSATION—On/Off (condensation detection)

DIFF PRESSURE—On/Off (differential pressure switch)

CUSTOMER ALARM—On/Off

Pressing ENTER and selecting TEST MICRO will permit the user to test the microcontroller and

associated circuitry on the Liebert XDC control board.
