How It Works

The zero-position sensor works as follows:

• Power supply from the SMC (stepper motor controller): 5 volts (+/- 10 %).
• Overvoltage protection: The overvoltage protection of the zero-position sensor is located in the SMC.
• Adaptation to the positioner module: The zero-position sensor is reset manually to adapt to the positioner module (end-of-production-line test by the manufacturer).
• Replacement value for the zero-position sensor: if the zero-position sensor fails, the headlights are aligned with a mechanical reference point (with a tolerance of up to +/- 1°).
