6.4 Overload Status Indicator
The LED designated "OVERLOAD", when illuminated, indicates the presence
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
• Communication error
A fault is detected if a transmitted value of '1' by the master controller does not
produce a threshold voltage at a corresponding output.
The I/O module switches the LED off again once the fault has been corrected.
The I/O module switches the LED off after a 1 second delay and and reset the
bit in the attribute Module Status Value.
