RS22/RS32
RS22/RS32 signal contact
The signal contact ("FAULT", for pin assignment of terminal block, see
fig. 17) monitors the functioning of the device, thus enabling remote di-
agnostics. You can specify the type of function monitoring in the Man-
agement.
You can also use the switch Web page to switch the signal contact
manually and thus control external devices.
A break in contact is used to report the following conditions via the poten-
tial-free signal contact (relay contact, closed circuit):
The detected inoperability of at least one of the two voltage supplies
(voltage supply 1 or 2 is below the threshold value).
A continuous malfunction in the device.
The loss of connection at at least one port. The report of the link status
can be masked by the Management for each port. In the delivery state,
link status monitoring is deactivated.
The loss of ring redundancy reserve.
A detected error during the self-test.
Incorrect configuration of the HIPER-Ring or ring coupling.
The following condition is also reported in RM mode:
Ring redundancy reserve is available. On delivery, there is no ring re-
dundancy monitoring.
Pull the terminal block off the device and connect the power supply
and signal lines.
