5.3View Event Log
In addition to alarms, the Liebert AC4 tracks other changes in the Event Log to assist users with verifying operational and troubleshooting problems. Events reflect changes in the status of an input that is defined as an event or the change of state of an output (i.e., manually forced ON or OFF). Other events may be informational, such as a user login. The Event Log contains up to 99 records of events, which are added as they occur.
To view the Event Log:
•From the Main Menu, use the arrows ↑↓ to choose View Status, then press Enter ↵.
•From the View Status Menu, use the arrows ↑↓ to choose View Event Log, then press Enter ↵.
5.3.1Event Log
The Event Log screen displays up to 99 recent events. If the log contains any event records, the Event Log screen displays details for each event:
•the event source (for example, DEVICE_1)
•the status of an input or output (CONTACT CLOSED) or a brief description of the event (USER LOGIN)
•the date and time the event occurred
Table 9 shows conditions that the event log records for inputs and outputs and in the panel itself.

5.3.2Backing Up the Event Log (Service Terminal Interface only)
The event log is stored as a file in the Liebert AC4; it can hold no more than 99 records. When the log is full, the oldest records are deleted from the end of the file as new event records are added at the beginning.
You may back up the event log file to a remote computer using the Service Terminal Interface, as described in 6.2 Back Up Log Files (Service Terminal Interface only).
To delete all records in the event log, see 7.10 Clear Alarms & Logs.
