9.3 Out-of-band signaling
The signal contact is used to control external devices and monitor the oper-
ation of the device. Function monitoring enables you to perform remote diag-
nostics.
The device reports the operating status via a break in the potential-free signal
contact (relay contact, closed circuit):
X Incorrect supply voltage,
the failure of at least one of the two supply voltages,
a permanent fault in the device (internal supply voltage).
X The temperature threshold has been exceeded or has not been reached.
X The removal of a module (for modular devices).
X The removal of the SCA.
X The interruption of the connection at at least one port. In the Basic Set-
tings:Port Configuration menu, you define which ports the device
signals if the connection is down (see on page 72 „Displaying connection
error messages“) . On delivery, there is no link monitoring.
X Event in the ring redundancy:
Failure of the redundancy (in ring manager mode). On delivery, there is
no ring redundancy monitoring.
X Event in the ring/network coupling:
Failure of the redundancy. On delivery, there is no ring redundancy
monitoring.
The following conditions are also reported by the device in standby mode:
– Defective link status of the control line
– Partner device is in standby mode
Select the corresponding entries to decide which events the device status
includes.
Note: With non-redundant voltage supply, the device reports the absence of
a supply voltage. You can prevent this message by feeding the supply volt-
age over both inputs, or by switching off the monitoring
(see on page 162
„Monitoring the device functions via the signal contact“) .
