7.8.4 Specify Hold Delay Time | Setup Operation Menu |
|
After an output changes state, the hold delay timer directs the Liebert AC4 to ignore all inputs in the same zone for the specified time.
This delay is the amount of time that must elapse before the Liebert AC4 acknowledges a change of state in any input. The default is 10 minutes (displayed as 10 MIN : 00 SEC).
The time delay applies only when a monitored output device changes from its normal
When the output device returns to its normal state, the Liebert AC4 acknowledges any input change of state immediately.
The hold delay timer also takes effect when the Liebert AC4 is powered up. All alarms are ignored until the hold delay time expires.

7.8.5 Specify Restart Time | Setup Operation Menu |

The restart delay timer directs the Liebert AC4 to wait a specified time before changing the state of an output. This feature can prevent needless responses to transient conditions.
If two or more outputs change state simultaneously, the Liebert AC4 begins a new countdown between each output change of state.
The default is 6 seconds (displayed as 00 MIN : 06 SEC).
