Short circuit/overload at an output module

Festo P.BE−CP−FB11−E−EN en 0802d
In the event of a short circuit or overload:
all the digital outputs of a string will be switched off,
the green LED Diag" on the output module will flash
quickly.
Please note
The outputs cannot be used again until the short circuit or
overload has been eliminated and the error deleted.
Deleting the error
You can delete the error by resetting all eight outputs. You
can do this in one of the following ways:
Possibilities
S Set all the outputs of the
output module to logical 0"
(RESET)
or
S Briefly interrupt the CP
connection at the CP output
module
or
S Briefly interrupt the operating
voltage for the CP system at
the field bus node
The outputs can then be used again. If the short circuit/over
load still exists, the outputs will be switched off again.
Explanation
Manually or automatically in
the program
Outputs on the output
module will be reset auto
matically.
All outputs of the CP system
will be reset automatically.
