5.3.11 CALIBRATE SENSORS

The temperature and humidity sensor can be calibrated by selecting this menu item. The tempera-

ture sensor can be calibrated ± 5°F and the humidity sensor can be calibrated ±10% RH. To prevent

coil condensation that could damage the Liebert XDC, the sensors must be calibrated to a known

source.

5.3.12 ALARM ENABLE

At the user’s discretion, some alarms may be enabled or disabled. If an alarm is disabled, the alarm

condition will not be monitored and will not trip, will not be in ACTIVE ALARMS, will not be in

ALARM HISTORY and will not be annunciated.

These alarms may be enabled or disabled:

FLOW LOSS P1—loss of refrigerant flow with Pump 1 alarm

FLOW LOSS P2—loss of refrigerant flow with Pump 2 alarm

CUSTOMER—customer alarm

HI RMT TEMP—high remote temperature alarm

LO RMT TEMP—low remote temperature alarm

HI LCL TEMP—high local temperature alarm

LO LCL TEMP—low local temperature alarm

To determine whether an alarm is enabled or disabled:

1. Press the MENU key.

2. Use the up and down arrow keys to move to the ALARM ENABLE menu.

3. Press the ENTER key to access the menu. Use the up and down arrow keys to move through the

menu and view which alarms are enabled or disabled. (YES means that the alarm is enabled, NO

means that the alarm is disabled.)

To change an alarm from enabled to disabled, or vice versa

1. Determine whether the alarm is enabled or disabled (see above).

2. Use the up and down arrow keys to scroll to the alarm to be changed.

3. Press the ENTER key. (The control will ask for a service password if passwords are enabled. Use

the up and down arrow keys and ENTER key to enter the three-digit password.)

4. Press the ENTER key again to change the alarm.

5. Press the ESC key two to three times to return to the main display.
