If the input GroupLink of this particular controller is used to provide the "group link"
information for two logical groups, then this setpoint is used to select which group
is located at the left side of the group link breaker (bus tie breaker). If this
particular controller is not used for the group link function adjust this setpoint to 1
(COMMON).

Group: Sync/Load ctrl
Setpoint: Voltage window
This setpoint adjusts maximum difference between generator and mains/bus
voltage in respective phases for voltage matching during synchronizing.
Requested angle between the phasors of the generator and mains voltage for
synchronizing. This setpoint is intended for correction of the phase shift caused by
a delta-triangle transformer located between the generator and mains voltage
measuring points. In other situations the setpoint should be adjusted to 0.
The diagram below shows a situation where the 230V/10kV triangle-delta
transformer causes 30° phase shift between the primary and secondary side. That
