6.5 Diagnosis
Specific faults of the multi I/O modules are registered or
suppressed 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 (MMI).
Depending on the module parametrizing, the faults are sent
to the field bus node, where they can be evaluated according
to the field bus protocol used.
6.5.1 Error messages of the multi I/O modules
A multi I/O module can register the following standard faults:
Fault
number Description Fault treatment
2 Fault short circuit/overload
Short circuit/overload in
sensor supply (V
EL/SEN
).
or (see continuation)
1. Eliminate short circuit/overload or check connected
sensors.
2. Depending on the parametrizing Reaction after
short circuit/overload in sensor supply (SCS)":
·
Setting V

Power supply for sensors will be switched on
again
automatically when short circuit is
eliminated.
·
Setting V
