The mini controller functions are:
• CONTROL:
– supplies the fuel solenoid pull-in and hold signals
– supplies the starter solenoid signal
• SAFETY:
– prevents the starter from being energized when the engine is
running
– prevents the engine from being started if the air end
temperature is too high or fuel level is low (optional)
– releases the fuel solenoid hold current if any switch in the
shutdown chain opens while the engine is running. It provides
bypass for engine oil pressure and water temperature for 20
seconds after initiating crank or until the engine is running.
