Time Delay
Time delay prevents unintentional activation-deactivation cycles. You can delay the time before the alarm is triggered when the alarm state goes from normal state to alarm state and when it goes from alarm state to reset state.
For example, an out of range alarm is configured with a 2 second time delay before the alarm is triggered, and a 3 second time delay before the alarm is reset. The monitored variable alarm exceeds the upper limit for 1 second before it returns to a value below the upper limit, but this does not trigger the alarm. The alarm is triggered when the variable has been in alarm state for more than 2 seconds. When the problem is corrected, the alarm must remain in normal state for longer than 3 seconds to reset.
Time delay can be added to all EcoStruxure Building Operation alarms except for system information alarms.
