4 . 5 Diagnostics
Specific faults of the multi I/O modules are registered or
suppressed depending on the module parameterization.
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 parameterizing, the faults are sent
to the bus node, where they can be evaluated according to
the field bus protocol used.
4.5.1 Error messages of the multi I/O modules
A multi I/O module can register the following standard faults:
Fault
num
b e r
Desc r iption Fault t r eatment
2 Fault s h o r t ci r cuit/ove r load
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 parameterization Behaviour
after short circuit/overload in sensor supply (SCS)":
·
Setting V
SEN
switch on again:"
Power supply for sensors will be switched on
again
automatically when short circuit is
eliminated.
·
Setting V
SEN
remains switched off":
Power off/on necessary
or
Modify parameter Behaviour to short circuit/
overload at sensor supply (SCS)" to
V
SEN
switch on again".
