Audible alarms
The PSUs incorporate audible alarms, which indicate when a fault state is present. A Voltage Out Of Range condition will activate the audible alarm.
The audible alarm can be muted by pressing the Enclosure ID button on the front operator’s panel.
Alarm interpretation
The following table summarizes the various interpretations when combining LED states and audible alarms. Use this table to help understand a pattern of lights and beeps. Each light/beep is taken in turn and shows linked items, so some of the data is duplicated in several places to make ease of search better.
Note: There will be no beep if the enclosure is muted.
