®
In parallel operation in accordance with the Automatic tap synchroniza-
tion method, the tap positions of the transformers running in parallel are
compared. It is therefore necessary that the transformers have the same
position designation and that the Raise and Lower signals produce the
same voltage change in all transformers.
NOTICE
Damage resulting from formation of circulating reactive current
If the parameters are not set correctly, damage may result from the forma-
tion of circulating reactive current and the resulting overload of transmission
lines and transformers.
► Check transformer nameplate.
► Set TAPCON® parameters in accordance with the configuration of the
transformers.
Before starting the function test, you must carry out the following steps:
1. Assign the master function to one TAPCON® [►Page 188].
2. Assign the follower function to the other TAPCON® units.
3. Compare the tap position displays of master and follower . All of
the TAPCON® units must display the same tap position. If this is not the
case, switch all TAPCON® units to the same tap position.

To perform the function test, proceed as follows:
1. Press on the follower to select manual mode.
2. If necessary, set the follower tapping direction.
3. Press on the master to select manual mode.
4. Press or on the master to manually change the tap position.
