Overload Status Indicator - WAGO 752 Owner's Manual

6.4 Overload Status Indicator

The LED designated "OVERLOAD", when illuminated, indicates the pres-
ence of an output fault.
Possible output faults:
• Short circuit of one or more outputs
• Missing supply voltage to the output drivers
• Fault of an output driver
• Feedback
A fault is detected if a transmitted value of '1' by the master controller does not
produce a threshold voltage at a corresponding output.
When an output fault is detected, the electronic module transmits a periphery
fault signal to the fieldbus controller board. The I/O module switches the LED
off again once the fault has been corrected, and after a 1 second delay, cancels
the periphery fault message.
