While the shade chipe is turinning with drawwork shaft, the infrared light in the gap of two photoelectric switches is guided or obstructed. Consequently, two series of voltage impulse signal is generated by photoelectric switches. The sensor is 4-wire system, defined as: +5V, 0V, signal A and signal B.
