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
reported correspondingly.
Mode parameter
The following table shows the "Mode" parameter.
