3.6. CHARGE INPUT TERMINAL

The Charge terminal is both an input and output.
When the engine is ready to run, this terminal supplies the excitation current to the charge alternator.
The excitation circuit is equivalent to a 2W lamp.
The threshold voltages for warning and shutdown alarm are adjustable through program parameter.
