• Input DC: Connect to various sensors and switches (e.g., oil pressure, engine temperature).
• AC Voltage Inputs: Connect to the generator and mains (utility) AC voltage sources for monitoring.
• AC Current Inputs: Connect to current transformers (CTs) for generator and load current monitoring.
• Charge Alternator: Connect for battery charging monitoring.
• Fikarohana andriamby: Connect for engine speed sensing.
• Comms Port: USB port for PC configuration and firmware updates.

5.3 Fampivoarana voalohany

After all connections are made and verified, apply DC power to the unit. The display should illuminate, and the controller will perform a self-test. Follow any on-screen prompts for initial configuration.

6. Torolàlana miasa

The DSE4520MKII offers intuitive operation through its front panel buttons and display. The primary modes of operation are Manual and Automatic.

6.1 Bokotra fanaraha-maso

• Stop Button (Red 'O'): Stops the generator and resets any active alarms.
• Auto Button (White 'AUTO'): Places the controller in automatic mode, allowing it to start and stop the generator based on mains (utility) supply status or other configured events.
