4.3.10CALIBRATE SENSOR

The local and the remote temperature and humidity sensors can be calibrated by selecting this menu item. The temperature sensor can be calibrated ± 5°F and the humidity sensor can be calibrated ±10% RH. To prevent coil condensation that could damage the Liebert XDP, the sensors must be cali- brated to a known source.

4.3.11ALARM ENABLE

Some alarms can be disabled or enabled as part of the user’s customized setup. An alarm that has been disabled will not report to the wall box beeper nor to the common alarm relay. Alarms are enabled by default.

Use the Up or Down arrow key to select a particular alarm; “YES” enables the alarm, “NO” disables the alarm. Press ENTER to save the change.

4.3.12ALARM TIME DELAY

Some alarms can be programmed with a time delay as a means of preventing nuisance alarms. This function specifies the amount of time an alarm must be present before the Liebert XDP recognizes and annunciates the alarm. If the alarm condition goes away before the time delay has expired, the alarm will not be recognized, and the time delay timer will be reset.

4.3.13COM ALARM ENABLE

Each individual alarm can be selected to energize or not to energize the common alarm relay. If the energize common alarm function is set to YES, the relay is energized immediately as the alarm is annunciated and de-energized when the alarm condition goes away (only after the alarm has been recognized). If the alarm is completely DISABLED, the alarm has no effect on the common alarm relay.

Use the Up or Down arrow key to scroll to a particular alarm, press the ENTER button to select it, then press the ENTER button to change the state (Yes or No).
