Voltage Signal: Description and Operation


Generator (Alternator) A

A dedicated output from the Generator is provided to the EMS2000 to determine electrical load on the engine. When electrical loads are switched on the generator will require more electrical energy, which will in turn create a greater load on the engine. The output is a PWM modulated signal.

If the PWM signal fails the engine may exhibit poor idle speed stability as the electrical loads are increased.
