Signaling faults
● The signaling of errors/faults by the signaling contact is synchronized with the fault LED
"F". All faults/errors indicated by the fault LED "F" (freely configurable) are also signaled
by the signaling contact.
● If an internal fault occurs, the fault LED "F" lights up and the signaling contact opens.
● If you connect a communications node to an unmonitored port or disconnect it, this does
not cause an error message.
● The signaling contact remains open until one of the following events occurs:
– The problem is eliminated.
– The current status is entered in the fault mask as the new desired status.
