NOTE
For the double arm move gun, teach a job so that the upper
side tip passes the sensor detecting zone when using the
sensor detection.
Also, set the polarity of the signal that is output from the
sensor, by the setting item “WEAR DETECT SENSOR
POLARITY” in chapter 1.12.3 "Spot Supervision Window
Setting".
