Figure 3-26 Receiver Cell
NOTES The emitter cell (Figure 3-16) is at the input of the conveyor, it has only one red
LED. This red LED should always be switched on and represents the status
“under voltage”.
The receiver cell (Figure 3-17) is at the output of the oven, it has 2 LED. The red
LED indicates input status (red light on = object detected, red light off = no object
detected), the green LED indicates signal quality.
2. For each cell, turn the adjustment screw to the max
position, then adjust the physical position of the receiver
or emitter until the green LED light is on.
3. Turn the adjustment screw counterclockwise until the
green light is off (position A).
4. Turn the screw in the middle position between max and A.
5. Check for positive detection with the board.
6. Check against another board to make sure the adjustment
is correct.
