4 Parallel regulation
With parallel regulation, you can determine whether the second regulator connected
through the E-LAN.

The switch information for the coupling needed (BIF coupling).
In the simplest form master-slave operation, the slave regulator blocked soon the
coupling the two regulators detected and the master has taken over the regulation. However, both regulators see the same zero sequence voltage Une soon
as they are switched the same compensation district. Use 'Move

We take care it.
Regulators that are installed further apart from each other cannot usually communicate
over the E-LAN. Moving the slave, however, will change the position the master's coil.
The regulators can operated master/slave 'parallel regulation without communica-
tion' (special feature).
An E-LAN connection recommended when both regulators are installed the same sub-
station because enables the regulators exchange information with each other real
time.
The slave's current coil position transmitted the master through the E-LAN and nec-
essary taken into account when calculating the compensation.

During tuning process, the master establishes that cannot reach the desired end posi-
tion.
The following parameters are available for master-slave parallel regulation and may only
be set for the master:
. sent one the
regulator's binary inputs through the SCADA system (prerequisite: SCADA connection
through REG-P, REG-PE REG-PED) can set permanently ON. only possible automatically
control both regulators the optional operating mode 'Parallel regulation without com-
munication'. calculate the P-coil's
target position, any fixed coils that are connected the master the slave regulator are
also taken into account
