The built-in vibration sensor detects when the engine is running and activates the converter only after a programmable delay (to avoid false starts). This is primarily used in vehicles where there is a warranty that could be invalidated by modifying the vehicle wiring. It allows the device to detect the engine running so no wiring modifications are needed. It can also use an alternative programmable input (e.g., D+, CAN-bus, or +15V signal). This ensures the starter battery isn't drained when the engine is off, prioritizing vehicle electronics—crucial for smart alternators that vary output (e.g., up to 15.4V in Mercedes). If detection fails, check the voltage threshold or use the purple wire (Pin 1) for manual activation (>2V threshold).
