A) - Turn the [KEY-switch] clockwise to [PREHEAT] position until all LEDs illuminate.

B) - Wait until the only [OIL PRESSURE] and [CHARGER FAILURE] LEDs remain illuminated. If the [PREHEAT] timer is set, the yellow LED [PREHEAT] will illuminate according to the setting of the potentiometer (adjustable on the back from 10 up to 60 seconds).

C) - As soon as the green [ENGINE RUNNING] LED starts blinking, turn the key switch clockwise up to the spring-loaded momentary position. Hold this position until the engine starts. The [ENGINE RUNNING] LED will blink for a period of about 15 seconds. If the engine does not start within this period, the [STARTING FAILURE ALARM] will take place.

D) - To stop the engine, turn the key switch fully counter clockwise (Off position).

In order to stop the engine, we recommend that you use a FUEL SOLENOID energized to run connected to the output #9 via a pilot (driver) relay. If you use a STOP SOLENOID, energized to stop, turn the potentiometer on the back fully clockwise and connect the STOP SOLENOID to output #8 via a pilot (driver) relay as indicated in the wiring diagram. The BE72 will provide a 60-second stop cycle for output #8. When you use the output #8 to drive a STOP SOLENOID, the ALARM function output will not be longer available.
