Diesel generator control system battery connection
The Be124 is extremely strong. You can supply it using 12V or 24V battery. The input circuitry is very well protected against over voltages and voltage spikes. The control software can survive as much as 500ms during the start sequence (especially when the controller energize the starter motor). When you turn the key to OFF, the controller shuts down all 'not used' circuits. It will take only a few mill-amperes from the battery. Even in OFF mode of operation the internal micro controllers are continuously running to keep the controller ready for use.
