The proximity sensor is located on the right upper corner of the main machine.
When the machine has been idle for a long period and the proximity sensor detects the presence of anyone in front of the machine, it signals the machine to prepare itself for quick recovery to operation status by shortening the time required for the machine to recover full operation (pre-recovery mode) before the operator even touches the machine or operation panel. The proximity sensor employs infrared and can detect the presence of the operator within an arc of 150° out to 1.8 m (6 ft.) away from the front of the machine.
The following diagram shows the image of the area covered by the sensor on the floor.
Basically, the sensor detects the presence of an operator coming to the machine from a distance of approximately 1.8 m. However, it may also detect the presence of someone walking across the area.
The infrared sensor’s detection performance is influenced by the ambient temperature. The sensing distance increases in a lower ambient temperature and decreases in a higher ambient temperature.
As a guide, the sensing distance starts decreasing from 1.8 m when the ambient temperature starts rising to 28 °C and above.
The sensor covers the area in front of the machine obliquely downward, detecting people’s legs (around their knees). Its sensing performance is influenced by the kind of clothes such people are wearing.
