DANGER!
Opening the communication converter
There is danger to life by energized parts.
Before opening the communication converter, it is absolutely necessary to isolate it
from the auxiliary supply voltage at all poles!
• Both devices at the link ends have to be switched on.
• First configure the communication converter CC-1:
– 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 7SA522 (ad-
dress &211(&29(5 for protection data interface 1 and
&211(&29(5 for protection data interface 2, see also Subsection 2.4.2).
– Move the communication converter into test position (jumper X32 in position 2-3).
– Close the communication converter housing.
• Reconnect the auxiliary supply voltage for the communication converter.
• The system interface (X.21 or G703.1) must be active and connected to the com-
munication converter. 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 doesn't close,
check the connection between the communication converter and the net (com-
munication device). The communication device must emit the correct transmitter
clock to the communication converter.
• Change the interface parameters at the 7SA522 (at the device front or via DIGSI
®
):
– Address &211(&29(5 = )RSWLFGLUHFW when you are testing pro-
tection data interface 1,
– Address &211(&29(5 = )RSWLFGLUHFW when you are testing pro-
tection data interface 2.
