7 SYSTEM AND CONTROL OPTIONS
NOTE: For ease of understanding, this section uses the LCD interface to illustrate most instructions,
except for features that are available only through the Service Terminal Interface. All Service Terminal
Interface screens appear in Service Terminal Interface on page109.
The System and Control menu allows you to configure the Liebert AC8—setting up inputs and outputs
and an input/output matrix to trigger actions, the modem and pagers, and system features such as date
and time. This menu also provides a vehicle for manually changing the state of an output to ON or OFF,
clearing active alarms and deleting records from the Liebert AC8’s alarm log, event log and trend logs.
The arrows are used to scroll through the menu. The Enter key is used to select the menu item and enter
new information. Table 7.1 below shows characters that may be entered in labels and values.
