7.10.2 Turn 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 AC8 tests all devices in Standby mode by putting each
device in operating mode for a designated time. If an operating unit is designated as disabled on alarm,
the unit is turned off during standby testing, then turned on when the test ends.
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.
