4.9 Connecting the signal contact (optional)
Note:
– To connect the signal contact lines, remove the 8-pin screw terminal block
on top of the repeater from the device.
– Use the correct pin assignment for the 8-pin terminal block.
– Make sure that the electrical insulation of the connection cables of the
signal contacts is sufficient. Incorrect connections can destroy the
repeater.
On the 8-pin terminal block on the top of the repeater, the unconnected pins
of a relay can be used as signal contacts. When the OZD Profi 12M ... is
working correctly, the contact is closed. If there is an error or a power failure,
the contact is opened.
The following problems with the network and the repeater can be signalled
by means of the signal contact:
Supply voltage interrupted
incorrectly connected
Internal device errors
Received data no input signal at port 3 (optical)
(The numbering of the ports depends on device variant)
no input signal at port 4 (optical)
(The numbering of the ports depends on device variant)
