8.3 Fault display (inactive)

An inactive fault is displayed by 

. If several faults have occurred, the number of faults 

will also be indicated. 

The message shown on the display below means that there has been a fault in the past 
but the device is no longer in fault condition.

If several fault messages have appeared, you can navigate through the faults using the 

and   buttons. In addition to the type of fault and the associated alarm value, you can 

see when the fault has occurred and for how long it has been active.
