7.7.2.2 Setting parallel operation method
You can use this parameter to set the parallel operation method. You can
select the following options:
Option Description
Master The device is designated as
the master.
Tap synchronization [►Sec-
tion 7.7.1.1, Page 138] par-
allel operation method
Follower The device is designated as
the follower.
Auto. tap synchroniza-
tion
Automatic assignment of
master or follower.
If a master is not detected,
the device with the lowest
CAN bus address is auto-
matically designated as the
master. All other devices are
designated as followers.
Circulating reactive
current
Circulating reactive current minimization with CAN bus
communication [►Section 7.7.1.2, Page 139] parallel op-
eration method
Power factor Circulating reactive current minimization without CAN bus
communication [►Section 7.7.1.3, Page 140] parallel op-
eration method
Table44: Setting parallel operation method
Only change the parallel operation method when the on-load tap-changers
are not performing tap-change operations.
To select the parallel operation method, proceed as follows:
1. Go to Settings > Parameters > Parallel operation > Parallel operation
method.
2. Select the desired option.
3. Press the Accept button to save the modified parameter.
7.7.2.3 Assigning a CAN bus address
You can use this parameter to assign a CAN bus address to the device. So
that all devices can communicate using the CAN bus, each device requires a
unique identifier. If the value is set to 0, then no communication takes place.
1. Go to Settings > Parameters > Parallel operation > CAN bus address.
2. Enter CAN bus address.
3. Press the Accept button to save the modified parameter.
