The following terms are used to describe the control and operation of the Liebert RAC2-8. For each term, both the operator actions and the system performance are defined. Refer to this section if necessary while setting up your system or to answer any questions about how the system operates.

Alarms

For each alarm condition or warning condition, the RAC2-8 locally annunciates the condition, locally displays the message, provides a time and date stamp, stores up to 20 messages in memory, and displays the message at a remote terminal. Alarms are produced for normal alarm conditions such as Common Alarm inputs and Temp/Hum alarms. Warnings are produced for conditions such as Manual Override.
