ENABLED
The IM-NT allows a closing of the BTB even in the case
that both buses (busL and busR) are connected to
different mains incomers. If synchronization is succesfull
BTB is closed.
NOTE:
Sometimes it is not possible to connect two mains
incomers together. Than this setpoint should be set to
DISABLE (see below) and "synchronization" (see note
below) will not start since the closing BTB command is not
issued.
DISABLED
The IM-NT will not close BTB if there are two different
mains incomers connected to the bus.
NOTE:
Passive phase/voltage check is performed before mains coupling.
NOTE:
The information about busL and busR being connected to mains is provided
by other IM-NTs connected on CAN and controlling corresponding MCBs and
MGCBs.
