  • Page 28: Stop Magnet Energised Time (P14)

    Stop Solenoid 4.5.9 Engine Started Signal (P15) The EAOM-19 must de-energise the Start solenoid, to disconnect the starter motor, once the engine is running. Conversely, if the engine does not start after the pre-set start time, the unit will turn off the starter motor and start again. Hence, the unit must be able to detect when the engine has started.

    High Temperature, will be ignored by the EAOM-19. Also, in the event of a mains failure, transfer of the load from mains to generator will be delayed until the end of the Control On Delay period. This period begins when the EAOM-19 has detected engine starting and has cut off the drive to the starter motor.
