Tab. 3/13: Error messages of the input modules
3-18
Specific faults of the input modules are registered or sup-
pressed depending on the module parametrizing.
The faults are shown on-the-spot by means of the Error LED
and, if necessary, can be evaluated with the handheld.
Depending on the module parametrization the faults are reg-
istered by the field bus node, where they can be evaluated
according to the field bus protocol used.
An input module can register the following standard faults:
Error treatment
1. Eliminate short circuit/overload or
). 2. Depending on parametrization (Para-
EL/SEN
check connected sensors
meters "Reaction after short circuit"):
Setting "Switch on voltage again":
•
Power supply for sensors will be
switched on again automatically
when short circuit is eliminated.
Setting "Leave voltage switched off":
•
– Power Off/On necessary
or
– Parameters "Modify Reaction after
short circuit" to "Switch on
voltage again".
