Commissioning

Note: The FO-Repeater requires no setting. Once all necessary connections have
been made, the device is immediately ready for operation.
Test Mode
Note: For the test mode, the FO-Repeater has to be connected to the end device as
shown in Figure 11. It is also possible to connect only one port.
The test mode Echo Mode is activated by shortly pressing the Reset / Echo Mode push-
button (< 1 s). In the Echo Mode, the data received on the receivers (R Logic) of port 1 and/
or port 2 is output again via the transmitters (T Logic) of port 1 and/or port 2 (Figure 13). The
Echo Mode is indicated by flashing of the red Error or Link Down/Echo Mode LED. The DR
relay is in the inactive state.

The Echo Mode enables testing of fibre-optic connections (port 1, port 2) between the FO-
Repeater and connected end devices. The end device sends data for the test to the FO-
Repeater and then receives them on the same interface. If the data sent is identical to the
data received, the fibre-optic connection between the FO-Repeater and the end device is
OK. The SIPROTEC 4 protection devices 7SD52, 7SD610, 7SA52 and 7SA6 indicate a
mirroring of data in the event log (event number 3217 for protection data interface 1 or 3218
for protection data interface 2).
By pressing the push-button for a longer time (> 1 s), a reset of the test operation and return
to the normal operating mode (Normal Mode) is triggered.
