7.8.2Turn Standby Testing On or Off

Standby testing permits scheduling an automatic operational check of devices in Standby mode.

When this feature is activated (ON), the Liebert AC4 tests all devices in Standby mode by putting each device in operating mode for a designated time. You may specify the time of day the testing begins, the duration of the test and the interval between tests. Standby testing is OFF (deactivated) by default.

To change the standby testing settings:

•From the Setup System Operation Menu, use the arrows ↑↓ to choose Standby Testing, then press Enter ↵.

•In the Change Standby Testing screen, press Enter ↵ to edit Standby Testing, then use the arrows ↑↓ to choose ON to activate or OFF to deactivate the standby testing feature. Press Enter ↵.

•Select the desired interval for how frequently the testing should occur in the Every 03 Days field. The default is 3 days; valid entries range from 0 to 99 days.

7.8.3Specify Failed Standby Response

The Liebert AC4’s Failed Standby feature determines what happens when an operating device fails and a standby device then becomes an operating unit. A subsequent alarm in the newly operating unit (previously the standby device) results in either restarting the previously operating device that was alarmed or not. This feature specifies whether each device remains in its current state or returns to its previous state of operation.

When this feature is activated (Y), each device returns to its previous state, as Table 19 shows: the newly enabled Standby device is disabled and the previously operating device is returned to Operating mode. The default setting is N (deactivated), meaning that each device remains in its current state: the Standby device remains enabled and the previously operating unit remains disabled.
