Proximity Sensor (Human Detection Sensor)

Overview
The proximity sensor (human detection 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 (human detection 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 (human detection 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.
