• Both devices at the link ends have to be switched on.
• First configure the communication converter CC-1:
– 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 transmission rate; they must
be identical with the parameterization of the 7SD5 (address
4502 CONNEC. 1 OVER
for protection data
interface 1 and, if required,
4602 CONNEC. 2 OVER
, see also Section 2.2.3.1).
– Move the communication converter into test position (jumper X32 in position 2-3).
– Close the communication converter housing.
• Reconnect the supply voltage of the communication converter.
• The communication network (X.21 or G.703.1) must be active and connected to the communication convert-
er. Check this by means of the "device ready" contact of the communication converter (continuity at the NO
contact).
– If the "device ready" contact of the communication converter does not close, check the connection
between the communication converter and the network (communication device). The communication
device must emit the correct transmitter clock to the communication converter.
• Change the interface parameters at the 7SD5 (at the device front or with DIGSI):
– Address 4502 CONNEC. 1 OVER = F.optic direct when you are testing protection data interface 1,
– Address 4602 CONNEC. 2 OVER = F.optic direct if you are testing protection data interface 2.
• Check the Event Log or spontaneous annunciations:
– Message 3217
„PI1 Data reflec“
(Protection interface 1 data reflection ON) when you test protec-
tion data interface 1,
– Indication 3218
„PI2 Data reflec“
(Protection data interface 2 data reflection ON) if you are testing
protection data interface 2.
– When working with both interfaces, note that the correct interface of the 7SD5 is connected to its associ-
ated 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 receiv-
ing 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 correctly?
– Are the fibre optic cables intact?
– Are the parameter settings for interface type and transmission rate at the communication converter
correct (see above; note the DANGER instruction!)?
– Repeat the check after correction, if necessary.
• Reset the interface parameters at the 7SD5 correctly:
– Address 4502 CONNEC. 1 OVER = required setting, if you are testing the protection data interface 1,
– Address 4602 CONNEC. 2 OVER = required setting, if are testing the protection data interface 2.
• Disconnect the auxiliary supply voltage of the communication converter at both poles. Note the above
DANGER instruction!
• Reset the communication converter to normal position (X32 in position 1-2) and close the housing again.
• Reconnect the supply voltage of the communication converter.
