Signaling of errors at the signaling contact
• The signaling of errors by the signaling contact is synchronized with the fault LED "F",
see section "LED display (Page 30)".
All errors that the fault LED "F" indicates (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.
