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.

5.5.1 Engine Stop Output (terminal 64 and 65)
Terminals 64 and 65 are a normally open contact. This output will be activated for the stop procedure until the stop time has expired (energized to stop). The output is activated both for normal stops and shutdowns. It is active in parallel with the stop solenoid relay.
Purpose of this output is to give a potential free signal to the shut.
The relay is normally de-energized

5.5.2 Run/ Stop Solenoid (terminal 66 and 67)
This output can be configured for control of the fuel valve (run solenoid) or stop solenoid.
Output configured for control of stop solenoid
In this case terminals 66 and 67 are the output for control of the stop solenoid. This output will be activated for the stop procedure until the stop time has expired (energized to stop) or (in case magnetic pick up is used for speed detection) until the engine speed is down to 10rpm (value depending on what is practical), both for normal stops and shutdowns.
The relay is normally de-energized. This output includes cable monitoring for the stop solenoid.
Note:
The RUN/STOP solenoid can only be used with 24V DC. This can be either the same supply as for the controller or a separate power supply. Please observe correct polarity when connecting the fuel valve.
When deactivated there will be a current of 5mA on this output due to the cable monitoring circuit inside the M2500.
Note:
The coil connected to this output must require a current > 5mA for activating. Otherwise the stop solenoid could be activated by the cable monitoring circuit.
This is especially important in case the stop solenoid is not activated directly by the M2500 output but by an intermediate relay, that typically requires a much lower current to activate than the stop solenoid.
The cable monitoring on this output can be disabled in the configuration, however the 5mA limit still applies.
In case the connection to the stop solenoid is lost and cable monitoring is enabled an alarm will be activated.

Output configured for control of run solenoid (fuel valve)
In this case terminals 66 and 67 are a normally open contact for control of the fuel valve. This output will be activated during start and operation of the engine (energized to run). For engine stop the output will be de-activated. The relay is normally de-energized. This output includes cable monitoring for the run solenoid.
Note:
Please note that this output can only be used with 24V DC. This can be either the same supply as for the controller or a separate power supply. Please observe correct polarity when connecting the fuel valve.
When deactivated there will be a current of 5mA on this output due to the cable monitoring circuit inside the M2500.

7.2 Alarm Monitoring
The alarm monitoring is always active regardless of Local or remote mode.
Note:
Alarms are abnormal conditions that will be indicated and logged by the M2500, but they will not stop the engine.
Alarms can be set to continuous monitoring (regardless if the engine is running or not) or conditional monitoring (only monitored if the engine is running).
An individual programmable time delay is available for each alarm. A new incoming alarm will always shift the M2500 display to the Current Alarm display. At the
same time the Alarm LED on the front panel will be fast flashing, the common alarm output (terminal 46) will activate and the Siren Relay (terminals 68, 69 and 70) will de-energize. Depending on the configuration it is possible to activate one or more of the digital outputs.
The common alarm output will de-activate for 2s and re-activate when a new alarm appear. The siren relay (terminals 68, 69 and 70) will de-activate for 2s and re-activate when a new alarm
appear. After accepting an alarm (by pressing the Reset button or external reset terminal 12) the common
alarm LED will change to steady light, the common alarm output and the optional digital output will remain active, provided the alarm is still present on the input. The siren relay will energize again after pressing Siren Reset or Reset button or external reset terminal 12.
When the all alarms disappear from the inputs and alarms have been acknowledged, the common alarm LED will switch off, the common alarm output and the optional digital outputs will deactivate.

7.3 Shutdown Monitoring
The shutdown monitoring is always active regardless of Local or remote mode.
Note:
Shutdowns are abnormal conditions that will be indicated and logged by the M2500 and they will stop the engine.
Shutdowns can be set to continuous monitoring (regardless if the engine is running or not) or conditional monitoring (only monitored if the engine is running).
An individual programmable time delay is available for each shutdown. A new incoming shutdown will always shift the M2500 display to the Current Alarm display. At
the same time the shutdown LED on the front panel will be fast flashing, the common shutdown output (terminal 46) will activate and the Siren Relay (terminals 68, 69 and 70) will de-energize. Depending on the configuration it is possible to activate one or more of the digital outputs.
Note:
A shutdown will block the engine for start until it has been reset and the shutdown signal has disappeared.
After accepting a shutdown (by pressing the ACK button or external reset terminal 12) the Common shutdown LED will change to steady light. The shutdown output and the optional digital output will remain active provided the shutdown is still active on the input. The siren relay will energize again.
