Page 7: Inputs
SELCO A/S M2500 Installation Manual 4 Inputs 4.1 Power Supply Redundant Power Supply (2x 24V DC, -30 % / +30 %) Alarm in case any power supply fails (common alarm + display text). Primary supply will not be monitored during cranking, as the battery voltage will drop during this process. -
Page 8: Connection Of Mode Selector Switch
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. -
Page 9: Remote Start (Terminal 8)
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. -
Page 10: Override (Terminal 10)
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. -
Page 11: Com (Terminal 13)
The magnetic pick-up is connected as follows: For use of magnetic pick-up the DIP switches 3 and 4 on the rear side of M2500 must be in OFF position. The DIP switches are placed between the RS485 and CAN connectors on the rear side of M2500. -
Page 12: Connection Of Pnp Pick-Up
The NPN pick-up is connected as follows: For use of PNP pick-up the DIP switch 3 on the rear side of M2500 must be in ON position, DIP switch 4 must be in OFF position. The DIP switches are placed between the RS485 and CAN connectors on the rear side of M2500. -

SELCO A/S M2500 Installation Manual 4.4.4 Connection of a normally closed sensor with cable monitoring The following example shows the connection of a normally closed sensor with cable monitoring. The sensor is considered active when open, inactive when connected to COM. -
Page 16: Analogue Inputs (Terminals 27 To 34)
The analogue sensor inputs are for generating alarms and shutdowns. In case the input signal is below 3mA or above 25mA the M2500 will generate a sensor fail alarm. Cable Error LED will be lit. Delay times can be programmed for alarms and shutdowns. -

Page 24: Run/ Stop Solenoid (Terminal 66 And 67)
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. - Page 25 This is especially important in case the fuel valve is not activated directly by the M2500 output but by an intermediate relay, that typically requires a much lower current to activate than the fuel valve.
