– Mains breaker control lines have to be wired to X25.13/
X25.14/X25.15/X25.16. These terminals are voltage free
contacts. The power for the MB has to be supplied by the
customer (24 Vdc/230 Vac) (max. contact rating K11,
K12 = 250 V /16 A).
– The Mains sensing lines L1/L2/L3/N have to be wired to
terminals X25.3/X25.4/X25.5/X25.6.
– Make sure the connections between X25.33 & X25.3;
X25.34 & X25.4; X25.35 & X25.5; X25.36 & X25.6 are
removed.
– Power Transducer lines have to be wired to X25.21 (input)
and X25.22 (GND).
– Verify all settings for paralleling set up (see
“Paralleling”).
Fixed Power (FP) operation
This application is possible in combination with SEMI-
AUTO mode or AUTO mode. Normally it is used in
combination with SEMI-AUTO mode in installations with
the Mains. The internal real time clock timer can only be
used in AUTO mode.
The generator will deliver a defined fixed power to the
load or to the Mains.

– Verify all settings for paralleling set up (see

Load Take Over (LTO) operation
This application is normally used in combination with
SEMI-AUTO mode or AUTO mode in installations with
the Mains.
The purpose of the load take over mode is to transfer the
load imported from the mains to the gen-set for operation
on generator supply only.
The generator will start-up, synchronise and take over the
load from the Mains gradually, before opening the Mains
Breaker. To know if the load is completely taken over
from the mains, an optional Power Transducer is
necessary.

Mains power export (MPE) operation
This application is possible in combination with SEMI-
AUTO mode or AUTO mode. The internal real time clock
timer can only be used in AUTO mode. Installation is with
the Mains.
The mains power export mode can be used to maintain a
constant level of power through the mains breaker. The
power can be exported to the mains or imported from the
mains, but always at a constant level.

Multiple gen-sets with load sharing
In this application the units are enabled to share the active
and reactive load equally in percentage of the nominal
power. The load sharing is active when each gen-set is
running in island mode and the generator breaker is
closed.
Multiple gen-sets with power management
(PMS)
PMS (= Power Management System) is a system that will
automatically start & stop generators based on the actual
load dependency. This will be done through a PMS
communication between the different units connected.
PMS applications are always in combination with AUTO
mode. If the SEMI-AUTO mode is selected, the PMS
operation will NOT function! The Qc4002™ controllers
from the gensets need to be programmed as PMS in
AUTO mode. When a Qc Mains controller is installed this
