The outputs can then be used again. If the short circuit/over-
load still exists, the outputs will be switched off again.
If there is a short circuit, overload or voltage fault in the
sensor 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 bit V (index 1002, byte 1, bit 4) will be set to"1".

Please note
The outputs cannot be used again until the short circuit or
overload has been eliminated and the error deleted.
Deleting the error/short circuit/overload
You can delete the error in one of the following ways:
S
Briefly interrupt the CP connection at the CP input module
or
S
Briefly interrupt the operating voltage of the CP system on
the CPV Direct
The inputs can then be scanned again. If the short circuit/
overload still exists, the error will be shown again.
Module CP-E16-M8-Z:
The short circuit/overload will be reset automatically and the
voltage will be switched on again.
