If there is a short circuit or overload:
– all the digital outputs of the module will be switched off
– the green LED "Diag" on the output module will flash fast
– the bit short circuit/overload of the diagnostic byte will be
set to "logical 1".
Please note
The outputs cannot be used again until the short circuit or
the overload is eliminated and the error is deleted.
Deleting the error
You can delete the error by resetting all eight outputs. You
can do this in one of the following ways:
Explanation
– Manually or automatically in the program
– Outputs on the output module will be reset
automatically
– All the outputs of the CP system will be reset
automatically
The outputs can then be reset to "logical 1".
If the short circuit still exists, the outputs will be switched off
again.
