Fault message Alarms
In an error situation the LED’s on the front will ash and the alarm relay will be activated. If you
push the top button in this situation you can see the alarm report in the display. If there are
further push again to see them.
There are two kinds of error reports - it can either be an alarm occurring during the daily opera-
