3.4 Short circuit/overload
Detailed information on input and output modules can be
found in the manual “CP modules electronics”.
3.4.1 Output module
If there is a short circuit or overload
– all the digital outputs of an output module will be
switched off
– the green LED “Diag” on the output module will flash fast
– the bit Short circuit/overload (Index 1002, byte 1, bit 2)
will be set to “1”.
Note
The outputs cannot be used again until the short circuit or
overload has been eliminated and the fault deleted.
Deleting faults
You can delete (quit) the fault by resetting all 8 outputs. You
can do this in one of the following ways:
Options Explanation
•
Set all the outputs of the output module to “0” (RESET)
or
•
Interrupt briefly the operating voltage for the
CP system
– Manually or automatically in the
program
– All outputs on the CP system will be
reset automatically
Tab. 3/14: Possibilities of deleting the fault
The outputs can then be used again. If the short circuit/
overload still exists, the outputs will be switched off again.
