7. Diagnosis with the ABB CS31
7.4.3 Short circuit in the sensor supply on an input module
7-14
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 fast
–
the error bit in the diagnostic byte will be set to "logical 1".
Please note
The inputs cannot be used again until the short circuit or
the overload is eliminated and the error is deleted.
Deleting the error/short circuit/overload
You can delete the error in one of the following ways:
S
Briefly interrupt the CP connection on the CP input module
or
S
Briefly interrupt the power supply to the CPV Direct
The inputs can then be interrogated again.
If the short circuit/overload still exists, the error will be shown
again.
