2.3 Conveyor unit
2.3.1 Check the conveyor sensor and its operation
The YRM20 is installed transmission type sensors as conveyor sensor.
The beam receiving condition of sensor varies depending the distance between the beam emitter and receiver
upon changing the conveyor width.
Upon changing the conveyor rail width, the Conveyor Sensor Tuning function is actuated to rewrite the sensor
threshold value automatically by remembering the changing receiving condition of sensor. It is required to be
checked periodically if it operates correctly.
