AUTION
!
IM-NT cannot influence behavior of another control unit that is in MAN mode.
It is dangerous to close GCB on gen-set in MAN mode while parallel
operation is disabled. IM-NT react on this with opening MGCB but it could
take short time till it received feedback from GCB and MGCB breaker is
automatically opened.

:
Connecting of a genset with non-ComAp controller to a
common bus
In version 2.5 it was not possible to close MGCB in case that all
ComAp genset controllers were switched off and there was another
(hire) genset supplying voltage to the bus bar.
From version 2.6 the IM-NT closes MGCB based on voltage present
on the bus (provided that load reserve is fulfilled) and is not checking
the presence of IGS-NTs. For proper functionality in parallel to Mains
operation it is then necessary that the MGCBparalClose setpoint is
set to YES.

Description
InteliMains is controlling the load sharing of the gen-set group). The value of
is related to the nominal power of each gen-set (i.e. if one gen-
set in the group has nominal power of 500 kW and another has 200 kW and
is set to 50%, first gen-set will produce minimally 250 kW and
the other will produce at least 100 kW). This function works regardless of
selected import/export limit or selected IMP/EXP control in parallel to Mains
operation.

:
is set to BASELOAD, the load sharing is done
by gen-set controller individually without any control from InteliMains. In this
case setpoint
Gener protect:
Min power PtM
in gen-set controller is
considered individually for each gen-set (i.e. it is possible to set different
minimal running power for each gen-set).
