3.6 Short circuit/overload
3.6.1 Output module
If there is a short circuit or overload:
1. all digital outputs of a string will be switched off
2. the green LED "Diag" on the output module will flash
fast
3. the short circuit/overload bit of the octets 9-12 "De-
vice-related diagnosis 2..5" will be set to logic "1".
PLEASE NOTE
The outputs cannot be used until the short circuit or
overload is eliminated and the error reset.
Reset error
In order to reset the error, the 8 outputs must be reset.
The following possibilities are available:
Possibilities Explanation
• Set all outputs of the output module
to logic "0" (RESET)
or
• Briefly interrupt CP connection on the
CP output module
or
• Briefly interrupt operating voltage of
the CP system on the fieldbus node
- manually or automatically in the program
- Outputs of the output module
are reset automatically
- All outputs of the CP system
are reset automatically
The outputs can then be operated again. If the short
circuit still exists, the outputs will be switched off again.
