1.7 Signal contact
Depending on the MACH 1000 device variant (equipped with one or two
power units), you have either one or two signal contacts.
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 also use the Management to switch the signal contact manually
and thus control external devices.
The potential-free signal contact (relay contact, closed circuit) reports
through a break in contact:
The failure of at least one supply voltage.
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.
Failure of the ring redundancy reserve.
Errors detected during the self-diagnostic 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: You can use the signal contact functions when the voltage supply is
connected. If there is redundant voltage supply, but this is turned off, there is
a contact interruption at the corresponding signal contact.
