5.5.1 Fault messages of the anaolgue output modules
An analogue output module can register the following faults:
F au l t num b e r D esc r i p ti o n F au l t t r eatment
2 Shor t ci r cuit /ov e rlo a d in vol ta g e
su pply
1)
Only with voltage outputs with signal
range 0...10 V:
Short circuit/overload at an output
(see Parameters Monitoring the
CPX module monitoring short cir
cuit/overload at output").
The reaction depends on the parame
trizing, parameter Behaviour after
short circuit/overload at output":
Setting Leave voltage/current
switched off":
The output is switched off.
Setting Switch on voltage/current
again":
The output current is limited to
approx. 15mA.
1. Check actuators, eliminate short
circuit/overload (number of faulty
channel: see LED display or module
diagnostic data).
2. Depending on parametrizing:
(Parameter Behaviour after short
circuit/overload at output")
·
Power off/on necessary
(operating voltage supply for
electronics/sensors V
EL/SEN
), or
change parameter Behaviour
after short circuit/overload at
output" to Switch voltage on
again".
·
The voltage will be switched on
again
aut o matica lly
when the
short circuit is eliminated.
1)
The module displays the relevant fault depending on the parametrizing. The analogue output
signals, however, will be processed further.
