the LCD to display Fuel Level. A pre alarm is programmed at 20%. A shutdown is programmed at
1%.
7.1.3 Low Water Level Switch (Digital) - A Low Water Level switch can be attached to Term 5 on the control
board. Use a normally open switch, which closes to ground. A shut down will occur when active.
7.1.4 Low Oil Level Switch - A Low Oil Level switch can be attached to Term 6 on the control board. Use a
normally open switch, which closes to ground. A shut down will occur when active.
7.2 In the case of a fault, the engine will be shut down, the red LED will illuminate and a message will appear on
the digital display defining the specific shutdown condition.
