1Preface
The M2500 - Engine Controller is designed for control and monitoring of marine engines.
Together with the optional M2600 - Shutdown Unit the M2500 - Engine Controller forms a
complete alarm, control and protective safety system for marine engines.
Typical applications are marine generator engines such as auxiliary generators, emergency
generators, harbour generators and propulsion engines.
The M2500 is designed for assembly in the main switchboard or at the engine.
This manual describes the installation of the M2500 - Engine Controller.

2Installation
The M2500 is designed for flush mounting to the front panel of the switchboard. It is secured by 6
mounting brackets which are supplied with the M2500.
The panel cut out dimension is 138mm x 210mm

4.2.1 Connection of Mode Selector Switch
The external mode selector switch is used for switching the M2500 into OFF, REMOTE or LOCAL
mode.
4.2.1.1 Local Mode (terminal 5)
The local mode input is considered active when connected to COM, inactive when open.
When active the M2500 will be in local mode. This means start and stop are only available from the
push buttons on the front panel. The remote start and stop terminals are disabled. The LOCAL LED
on the front panel will be lit. Not ready LED on the front panel will be lit and READY output
terminal 36 will be deactivated indication that the engine is not available for remote start.
4.2.1.2 Remote Mode (terminal 6)
The remote mode input is considered active when connected to COM, inactive when open.
When active the M2500 will be in remote mode. This means start and stop are only available from
the REMOTE START and REMOTE STOP terminals. The Local start and stop push buttons are
disabled.
Provided no alarm, shutdown or Off command is active, the green REMOTE LED on the front
panel will be lit and the engine is ready for remote start.
4.2.1.3 Off (terminal 7)
The off input is considered active when connected to COM, inactive when open.
When activated, the M2500 will initiate a stop procedure. Engine start will be blocked as long as
this input is active.
Not ready LED on the front panel will be lit indicating that the engine is not available for remote
start.

4.2.2 Remote Start (terminal 8)
The Remote Start input is considered active when connected to COM, inactive when open. It can be
a pulse or continuous signal.
The input is only enabled in remote
mode.
When activated, the M2500 will
generate a start signal to the engine.
The pre-configured number of start
attempts is available. During the start
attempt the green Engine Running
LED on the front panel will be fast
flashing. During the rest periods
between start attempts this LED will
be slow flashing. When the engine is
running, the LED will be lit continuously.
If the engine does not start the M2500 will initiate a stop procedure and a Start Fail Alarm. The red
ALARM LED on the front panel will be lit. The alarm text “START FAILURE” will be shown on
the display.
4.2.3 Remote Stop (terminal 9)
The Remote Stop input is considered active when connected to COM, inactive when open. It can be
a pulse or a continuous signal.
The input is only enabled in remote
mode.
When activated, the M2500 will
initiate a stop procedure. During the
stop procedure the green Running
LED will be slow flashing. The
Stopping LED will be lit. If the
engine does not stop the M2500 will
generate a Stop Fail Alarm. The red
ALARM LED on the front panel will
be lit. The alarm text “STOP
FAILURE” will be shown on the
display.
The engine will be blocked for start as long as the stop input is active. When activated
simultaneously, Stop overrides Start.

Revision: 23-04-2012 Page 10
4.2.4 Override (terminal 10)
The Override input is considered active
when connected to COM, inactive
when open.
When activated all shutdowns that are
marked override will be disabled,
meaning the engine will continue
running despite of a shutdown. If the
override is deactivated while a
shutdown is present, shutdown will be
executed immediately.
4.2.5 Crank Disconnect (terminal 11)
The Cranck Disconnect input is
considered active when connected
to COM, inactive when open.
This input is only used in case
there is no pick-up for speed
detection. The input is a contact
from a tacho-relay that signals
that the speed of the engine is
above ignition speed. When
receiving the Crank Disconnect
signal the M2500 will deactivate
the crank output after a start
attempt. If the M2500 looses this
signal without a stop procedure, the ALARM LED will be lit and a Tacho Fail Alarm will be
displayed.
4.2.6 Reset (terminal 12)
This Reset is considered active when
connected to COM, inactive when open.
When activated, this input will reset the siren
and the alarm/ shutdown.
