Display
If no external supply voltage is connected, switching off supply voltages 1U
leads to switching off the associated channel status LED Qn.
Response to error detection
All channels that are in pause mode on "PE_MODE_PROCEED" report their diagnostic
status as in productive mode.
The following applies for all channels which switch to a different pause mode:
● During the "pause", error detection of "Load voltage 2L+" is not possible:
– Alarms for errors already pending before the "pause" are retained.
– After the "pause" is over, the error status is updated and incoming/outgoing errors are
