The IR Photoreflector is not responsive


Normally, the value of IR photoreflector is greatest if placed 6 to 10 mm from the surface of the object. If the sensor still doesn't react while approaching your finger or another object, enter coding block such as "IR photoreflector < ◯" using the value obtained at 6 to 10 mm from the object as the basis for ◯.

If despite this, the sensor still doesn't work please inquire at customer service.
