Checking a
Connection with
the Communication
Converter using
Direct Link
If a communication converter is used, please note the instructions enclosed with the
device. The communication converter has a test setting where its outputs are looped
back to the inputs.
Links via the communication converter are tested by means of local loop-back (Figure
8-18, left).
Figure 8-29
Distance protection communication via communication converter and communication network -
example
o
Both devices at the link ends have to be switched on.
o
First configure the communication converter CC-1:
G
Disconnect the auxiliary supply voltage from both poles.
G
Open the communication converter.
G
Set the jumpers to the matching position for the correct interface type and transmis-
sion rate; they must be identical with the parameterization of the 7SA6 (address
4502
CONNEC. 1 OVER
for protection data interface 1 , see also Section 6.4.2).
G
Move the communication converter into test position (jumper X32 in position 2-3).
G
Close the communication converter housing.
o
Reconnect the auxiliary supply voltage for the communication converter.
o
The system interface (X.21 or G.703.1) must be active and connected to the commu-
nication converter. Check this by means of the "device ready"-contact of the commu-
nication converter (continuity at the NO contact).
o
If the the "device ready"-contact of the communication converter doesn't close, check
the connection between the communication converter and the net (communication de-
vice). The communication device must emit the correct transmitter clock to the com-
munication converter.
o
Change the interface parameters at the 7SA6 (at the device front or via DIGSI® 4):

DANGER!
Before opening the communication converter, it is absolutely necessary to iso-
late it from the auxiliary supply voltage at all poles! There is a danger to life by
energized parts!
