11.2.1.29 Setpoint: Mains coupling
This setpoint selects how the IM-NT cooperates with other IM-NT in systems
where one common busbar is supplied from many mains incomers, which are
controlled by many IM-NT controllers.
If there is voltage on Bus, however it is supplied from
other mains incomer controlled by other IM-NT, the
respective IM-NT may also close its MCB and MGCB and
it will couple the two mains incomers together.
The IM-NT will not close it's MCB and MGCB if there is
other IM-NT with closed MCB and MGCB detected on the
CAN2 bus (in the same control group - control groups may
be connected together via Group Link).
NOTE:
Passive phase/voltage check is performed before mains coupling.
11.2.1.30 Setpoint: AUT ctrl mode
This setpoint selects how the MCB is handled in AUT mode.
The MCB is controlled by IM-NT and it's internal
sequences and adjusted timers.
The MCB is expected to be controlled by an external
device (e.g. a PLC) and the IM-NT only follows it's
position. Synchronizing can be activated by the input
