If there is a short circuit, overload or voltage fault in the sen
sor supply:
the sensor supply for all inputs of the module will be
switched off.
the green LED Diag" on the input module will flash
quickly.
the fault bit in the diagnostic byte will be set to
logical 1."
Please note
The outputs cannot be used again until the short circuit or
overload has been eliminated and the fault deleted.
Deleting the fault / short circuit/overload
You can delete the fault in one of the following ways:
Briefly interrupt the CP connection at the CP input module
·
or
Briefly interrupt the operating voltage for the CPV Direct
·
The inputs can then be scanned again.
If the short circuit/overload still exists, the fault will be shown
again.
