Photoelectric Sensor (uncommon for North American "U" model)

[How to change sensitivity]

Check detecting condition of hopper level meter (photoelectric switch) on molding machine.

The photoelectric switch usually does not need adjustments (constantly used at maximum sensitivity). But if light-cutoff condition (i.e. when molding material is loaded) is not sufficient, turn sensitivity volume to the left for green lamp to light up. Operation Selector switch should be used by setting at L-side (with ON light).
