2.Use the Up or Down arrow key to view the messages.

3.Press the ENTER button to select the message to be displayed.

4.3.15CUSTOM 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.

4.3.16DIAGNOSTICS

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

CTR VALVE XX.Xma—OPEN/CLOSE (control valve and 4-20mA feedback signal) GREEN LAMP—On/Off

RED LAMP—On/Off COMMON ALARM—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 XDP control board.
