7.8Setup Operation
The Liebert AC4 operation features allow you to set up a rotation sequence to alternate which devices are operating and which are placed on Standby, as well as test devices while in Standby mode and specify what to do when a Standby device goes into alarm as it is powered up. You may also specify delay times after an output changes state, directing the Liebert AC4 to wait before acknowledging inputs or turning an output on or off.
