Board at Left/
Right Optos
The board at left/right optos switching threshold can be adjusted by means of a
sensitivity control. This ensures that when a board is fed into the machine (via
the transport belts) the sensor output switches to ON.
To achieve an optimum setting carry out the following procedure:
1. Place a board on the rails covering the sensor.
2. Turn the sensitivity control fully anti-clockwise, ensure that the amber LED
is extinguished.
3. Re-adjust the sensitivity control clockwise until the amber LED illuminates.
NOTE
If the amber LED is flashing, this indicates a week signal. Re-adjust the
sensitivity control.
4. Remove the board from the rails and confirm the amber LED extinguishes.

5. Turn the board 90° and position back onto the rail system, (so that the board
lies on top of the rail system as shown in the figure below).
6. Confirm that the amber LED is extinguished. If the amber LED illuminates,
turn the sensitivity control anti-clockwise until the amber LED extinguishes.
7. Remove the board.
8. Position the board back on the rail system, as in Step 1, and confirm that the
amber LED illuminates.
9. If the board has holes or cut-outs, go to Step 11.
10. Go to Step 14.
11. Slide the board backward and forward across the sensor ensuring that the
LED is only triggered by the leading and trailing edges of the board.
12. If the LED flickers when encountering holes or cut-outs, turn the sensitivity
control clockwise a further quarter turn.
13. Repeat Steps 11 and 12 until the correct setting is achieved.
14. Remove the board from the rails and confirm that the amber LED extin-
guishes.
