OVERVIEW
The Model 402 is a Waterproof Manual Engine Control Module. The module is used to start and stop the engine, indicating any fault conditions, automatically shutting down the engine and indicating the engine failure by a steady red LED on the front panel.
Operation of the module is via a 3 position waterproof key-switch with STOP(O), RUN(I) and START(II)
positions. Turning the switch to the position will initiate a pre-heat relay for a period of 10 Seconds. Pre-heat operation is indicated by LED. Once the timer has expired the pre-heat relay will de-energise and the LED will extinguish.
The FUEL relay will then energize and the Safety On delay timer will commence.
Pre-heat mode can be overridden at any time by turning the switch from the position to the position while the preheat LED is illuminated.
