•Configure start and stop DI’s and Throttle profile.
•Set the keyswitch is in the “Auto” position
•Activate the DI1 or DI2 inputs configured for Start.
Enable Auto Start Mode
To use the Auto Start feature the M300DP Mode must be set to A/S. See
the section on M300 Setup.
Set the Keyswitch in the “Auto” Position
When the ignition switch is placed in the “Auto”
position (keyswitch in a fully counter-clockwise
position) an ALERT will be displayed on the
main engine display. This window will display for
approximately 1 minute. The system will then
enter a power save mode, waiting for the
AutoStart input to activate.
NOTE: If the ignition switch is in the “ON” position the AutoStart feature
will not activate.
Activating the AutoStart input
There are two discrete inputs, DI1 and DI2,
which may be used to initiate an Auto Start
sequence. See the Installation section of this
manual for more information.
Selecting “A/S” enables
the AutoStart Mode

Make External Connections
To connect the two analog inputs and the two discrete inputs to the
sender(s), five pigtails are provided and must be inserted into the Engine
harness. The recommended pin locations are shown in Table 4.
The installer is responsible for making the connection from each pigtail to
the device(s) (Oil Pressure Sender, Fuel Sender, Float Switch, etc.).

When the Auto Start input is activated, the M150L Series will exit the
power save mode and indicate an impending engine start sequence by
generating a countdown sequence to engine start. If the system has been
wired for an alarm, an audible alarm will be heard during this time. See
the Installation section of this manual for more information.
Starting the Engine
Once the countdown is complete the module will
activate the start input to the engine. The
screen will read “ENGINE START NOW” and
the starter will remain active for 10 seconds or
until the engine is running. If the engine does
not successfully start during this time the starter
will turn off.
Once Auto Start has been activated the display
will switch to the Requested Speed screen and it
will reflect the engine speed and ramp times
programmed in the Throttle Profile. See the
section on setting the Throttle Profile.
Auto Start Failure
If the engine fails to start after the initial 10
seconds and the configured retries, the display
will show the “Autostart Failed” screen. At this
point the operator will need to cycle the key
switch before the M300DP module will attempt
to start the engine again.
