Output current
has been exceeding the
programmable current trip.
If the measured output current exceeds the programmed current trip then the corresponding bits will be set.
The output voltage is not present and the channel is ‘OFF’ (Bit o = 0 in ‘Status channel’). A programmed
current limit with value zero has no effect to the current flow.
The setting bits in DATA_1 and DATA_0, the bit t in ‘Status channel’ and the bit z in ‘General status module’
will be reset after this access.
With help of the ‘Group access’ ‘Switch
ON
/OFF’ the concerning channels are switched ‘ON’ again.
