• Check the operating indications or in the spontaneous annunciations:
– Message 3217 ´3, 'DWD UHIOHFµ (Protection interface 1 data reflection ON)
when you test protection data interface 1,
– Message 3218 ´3, 'DWD UHIOHFµ (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 7SA522
relay is connected to its associated communication converter.
– If the indication is not transmitted check for the following:
– Has the 7SA522 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 7SA522 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.
• Reset the interface parameters at the 7SA522 correctly:
– Address  &211(&  29(5 = required setting, when you have tested pro-
tection data interface 1,
– Address  &211(&  29(5 = required setting, when you have tested pro-
tection data interface 2.
• Disconnect the auxiliary supply voltage of the communication converter at both
poles. Note the above DANGER instruction!
• Reset the the communication converter to normal position (X32 in position 1-2) and
close the housing again.
• Reconnect the supply voltage of the communication converter.
Perform the above check at the other end with the device being connected there and
its corresponding communication converter.
Continue with the margin title "Consistency of Topology and Parameterization".
Having performed the above checks, the linking of a device pair, including their com-
munication converters, has been completely tested and connected to auxiliary supply
voltage. Now the devices communicate by themselves.
• Check now the Event Log or in the spontaneous annunciations of the device where
you are working:
– Message FNo. 3243 ´3, ZLWKµ (protection data interface 1 linked with) fol-
lowed by the device index of the other device, if interface 1 is applying. For pro-
tection data interface 2 the message is FNo 3244 ´3, ZLWKµ.
– If the devices are at least connected once, the message FNo. 3458
´&KDLQWRSRORJ\µ will appear.
– If no other devices are involved in the topology as an entity, the message FNo.
3464 ´7RSRO FRPSOHWHµ will then be displayed, too.
