Once the controller detects soft detonation on one of the sensors (this is a specific stage before real detonation occurs), several steps will take place:
- Alarm signal turns on
- Ignition retard by 0 to 5 V or 4 to 20 mA analog output.
- If this action does not cure the detonation, the load reduction output will be activated.
- If the load drop does not stop the engine from detonating the engine STOP output will be activated.
