“FAULT” signal contact
The signal contact (“FAULT”, for pin assignment of terminal block, see
figure 12
) monitors the functioning of the device, thus enabling remote
diagnostics.
The potential-free signal contact (relay contact, closed circuit) reports
through a break in contact:
The detected inoperability of at least one of the two voltage supplies
(voltage supply 1 or 2 is below the threshold value).
The device is not operational.
The defective link status of at least one port with active link monitoring. In
delivery state, link monitoring is inactive.
Failure of the ring redundancy reserve.
Errors detected during the self-diagnostic test.
Pull the terminal block off the device and connect the power supply and
signal lines.
2.7
Mounting the terminal block
Mount the terminal block for the voltage supply and signal contact on the
front of the device using the snap lock. Verify that the snap lock latches in
place.
2.8
Operating the device
By connecting the supply voltage via the terminal block, you start the
operation of the device.
2.9
Connecting data cables
In general, adhere to the following recommendations for data cable
connections in environments with high electrical interference levels:
Keep the length of the data cables as short as possible.
Use optical data cables for the data transmission between the buildings.
