Operator Control and Display Panel

9.0OPERATOR CONTROL AND DISPLAY PANEL

9.1Operator Control Panel

The control panel and LCD on the front of the Liebert® APM™ lets the operator:

•Turn the UPS On or Off.

•Transfer into the various operating modes.

•Silence alarms.

•Check the status of the UPS and its batteries, including all measured parameters, events and alarms.

The main areas of the control panel are shown below in Figure 51 and explained in Table 23.

•Mimic Display - view the status of the Liebert APM in single-line diagram format—indicators show status by changing color when ON, flashing or OFF

•Liquid Crystal Display (LCD) and Navigation keys - view status and operational data from the Liebert APM in tabular format

•Control buttons - turn the Liebert APM on or off, silence alarms
