Signaling contact

The signaling contact (relay contact) is a floating switch with which error/fault states can be
signaled by breaking the contact.
Error indication
● The signaling by the signaling contact is synchronized with the fault LED, in other words,
all errors displayed by this LED (freely configurable) are also signaled on the signaling
contact.
● If an internal fault occurs, the fault LED lights up and the signaling contact opens.
● The connection or disconnection of a communication node on an unmonitored port does
not lead to an error message.
● The signaling contact remains activated until the error/fault is eliminated or until the
current status is entered in the fault mask as the new desired status.
