1.7 Signal contact
Depending on the device variant (equipped with one or two power supply
units), one or two signal contacts are available.
 The signal contact is a potential-free relay contact.
The device allows you to perform remote diagnosis via the signal contact.
In the process, the device signals events such as a line interruption. When
an event occurs, the device opens the relay contact and interrupts the
closed circuit. The management setting specifies which events switch a
contact.
You can also use the management to switch the signal contact manually
and thus control external devices.

You can use the Management to set the signal contact manually and thus
control external devices.
The potential-free signal contact (relay contact, closed circuit) reports
through a break in contact:
 At least one power supply is inoperable.

The device is not operational.

The failure of the connection on at least one port.
The report of the link status can be masked by the Management for each
port. In the delivery state is deactivated.
 Loss of the ring redundancy reserve.
 A detected error during the self-test.

Incorrect configuration of the HIPER-Ring or ring coupling.

Permitted temperature range exceeded/not reached.
The following condition is also reported in RM mode:
 Ring redundancy reserve is available. On delivery, there is no ring
redundancy monitoring.
Note:
The signal contact functions are available when the power supply is
connected. If a redundant power supply is present but switched off, contact
interruption occurs at the associated signal contact.
