Please note
Please note when using the multi I/O modules:
If there is a short circuit, all sensor supplies will be
switched off together.
If not parametrized otherwise, the sensor supply voltage
will be switched on again automatically when the short
circuit is eliminated.
Fault treatment
1. Check actuators, eliminate short circuit/over
load (number of faulty channel: see module
diagnostic data).
2. Depending on the parametrizing Reaction
after short circuit/overload at outputs (SCO)":
Set output to 0, then set to 1 again or
·
modify parameter Reaction after short
circuit/overload at outputs (SCO)" to V
switch on again".
If the output current is lower than 400 mA:
·
The voltage will be switched on again
automatically when the short circuit is
eliminated. If the output current is greater
than 400 mA:
Set output to 0, then set to 1 again.
Check the load voltage
