Pure parallel
operation. No
island
operation, no
AMF function.
Neither MCB
nor MGCB is
synchronized.
The group is activated by
the input
Sys Start/Stop .
Then MGCB is closed to
power the genset bus.
After that the gen-sets are
started and sychronized to
the already powered bus
and continue in parallel
operation until the group is
deactivated or mains is
failed.

MGCBparalClose = YES
Pure island
operation with
AMF feature.
No parallel
operation,
neither MCB nor
MGCB is
synchronized.
The group is activated
automatically after the
mains failed. As soon as
the system reserve is
reached the MGCB is
closed and the group
supplies the load. When
the mains returned MGCB
is opened and the group is
stopped. Island enable = YES
ParallelEnable = NO
Synchro
enable
= NONE
MFStart enable = YES
Parallel and
island operation
without AMF
function. MCB is
not
synchronized.
The group is activated by
the input
Sys Start/Stop .
Closing of MGCB while in
parallel operation depends
on the position of the
setpoint
MGCBparalClose .
In island operation the
MGCB is closed when the
group has reached the
adjusted system reserve.
When the group is
deactivated first the MGCB
is opened and then the
gen-sets are stopped. If a
mains failure occurs while
the group is in parallel
operation the MCB is
opened and the group
continues in island
operation. When the mains
returns the group remains
in island operation as
reverse synchronizing is
disabled.
