The drive unit is stopped and the display flashes once. During this time, it is repeatedly determined whether the first part of the sensor is normal or broken.
) Returns if normal. Sensor 2 The same is true when the 3rd part of the sensor breaks down, and it is repeatedly determined whether it is normal or broken, and if it is normal, it returns to normal operation. Effects of the invention (1) To the case where the detection part breaks down.Each detection part By prioritizing each function according to its importance, controlling each function, and displaying each display, the user can determine which sensor part has failed. In the event of a failure, the user may be able to use the system to some extent by performing emergency operation. If
