Note: A fault record can be generated by connecting one or a number of
contacts to the “Fault Record Trigger” in PSL. It is recommended that
the triggering contact be ‘self reset’ and not a latching. If a latching
contact were chosen the fault record would not be generated until the
contact had fully reset.
