Sensor Supply On One Input Module - Festo CPV-D102 Elektronics Manual

3.5.2 Sensor supply on one input module

3−28
If there is a short circuit, overload or voltage fault in the
sensor supply:
the sensor supply of all inputs of the module will be
switched off
if it exists, the diagnostic LED on the output module will
light up, otherwise the green LED will flash
the fault bit V
sen
will be set to 1.
Note
The inputs cannot be used again until the short circuit or
overload has been eliminated and the fault quitted.
Deleting faults
You can quit the fault in one of the following ways:
interrupt briefly the CP connection on the CP input module
or
interrupt briefly the operating voltage for the CPI system
on the CPV Direct.
The inputs can then be scanned again. If the short circuit/
overload still exists, the fault will be shown again.
Module CP−E16−M8−Z:
The short circuit/overload will be reset automatically and the
voltage will switched on again.
