3 Mounting and Commissioning
• Both devices at the link ends have to be switched on.
• First configure the communication converter CC-1:
• Reconnect the supply voltage of the communication converter.
• The communication network (X.21 or G.703.1 or ISDN) must be active and connect-
• Change the interface parameters at the 7SD5 (at the device front or via DIGSI
• Check the Event Log or spontaneous annunciations:

– Disconnect the auxiliary supply voltage from both poles.
– Open the communication converter.
– Set the jumpers to the matching position for the correct interface type and trans-
mission rate; they must be identical with the parameterization of the 7SD5 (ad-
dress 4502 CONNEC. 1 OVER for protection data interface 1 and, if re-
quired,4602 CONNEC. 2 OVER, see also Section 2.2.2.1).
– Move the communication converter into test position (jumper X32 in position 2-3).
– Close the communication converter housing.
ed to the communication converter. Check this by means of the "device ready"
contact of the communication converter (continuity at the NO contact).
– If the "device ready" telay of the communication converter doesn't close, check
the connection between the communication converter and the net (communica-
tion device). The communication device must emit the correct transmitter clock
to the communication converter.
– Address 4502 CONNEC. 1 OVER = F.optic direct when you are testing pro-
tection data interface 1,
– Address 4602 CONNEC. 2 OVER = F.optic direct when you are testing pro-
tection data interface 2.
– Message 3217 „PI1 Data reflec" (Protection interface 1 data reflection ON)
when you test protection data interface 1,
– Message 3218 „PI2 Data reflec" (Protection interface 2 data reflection ON)
when you test protection data interface 2,
– When working with both interfaces, note that the current interface of the 7SD5 is
connected to its associated communication converter.
– If the message is not transmitted check for the following:
– Has the 7SD5 fibre optical transmitting terminal output been correctly linked with
the fibre optical receiving terminal input of the communication converter and vice
versa (no erroneous interchanging)?
– Does the 7SD5 device have the correct interface module and is it working cor-
rectly?
– Are the fibre optic cables intact?
– Are the parameter settings for interface type and transmission rate at the com-
munication converter correct (see above; note the DANGER instruction!)?
– Repeat the check after correction, if necessary.
