6.5 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.
6.5.1 24 VDC signaling contact (XR-300M EEC)
The signaling contact is connected to a 2-pin plug-in terminal block.
