Wiring
Engine kill relay
On the contactor 1 connect a relay. The relay should be normally closed and ensure shutting down the engine when the contactor is not powered.
You can configure a voltage that is used for controlling the relay using /common/contactor1/attack and /common/contactor1/hold. Negative value means a voltage, positive a duty cycle.
Do not use the app without the kill relay. In emergency situations, the controller is able to shut down the engine.
Generator turn on switch
To start the generator, add switch between GPIO1 and +5V. When you switch it on, the controller will start the generator, when you switch it off, the controller will stop the generator.
If you want to start the generator automatically with powering the controller, set parameter IN_gen to 0. The controller will start the generator automatically when powered on.
