Fault Reset
You can reset all output channels in error status by briefly connecting the selected reset channel to
ground.
A reset channel can be assigned as an event. In this case any input - analogue, digital or CAN –
and the dedicated warning light output can be assigned.
Use the event settings to define the switching conditions.
Resetting PCM2 only affects channels in error state. The reset function will not reboot the PCM in
general and has no influence on outputs in normal operation state. It will only reboot channels
which have switched off after their pre-defined automatic resetting conditions.
Please see section 5.3.1.13 for setting up a reset event.
The reset will reboot channels which were shut down due to overload of OCH, OCL and OCS.
