Fault
When a NC (Normally Closed) contact has a discontinuity longer than the set in
time interval, it is a FAULT, for NO (Normally Open) contact continuity for a period
longer than the set in time interval constitutes a fault. When a FAULT is detected
the FAULT LED for that channel illuminates and a +12 V signal is present on the
FAULT output terminal on the rear panel. To remove the fault the FAULT RESET
switch should be depressed, this removes the fault from all channels. The FAULT
RESET can be accomplished remotely by ap12 volts to the RESET
terminal on the rear panel.
