16.4.2 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:
► Place a board on the rails covering the sensor.
► Turn the sensitivity control (1) fully anti-clockwise, ensure that the amber LED (2) is OFF.

► Re-adjust the sensitivity control (1) clockwise until the amber LED (2) is ON.
NOTE
If the amber LED is flashing, this indicates a week signal. Re-adjust the sensitivity control.
► Remove the board from the rails and confirm the amber LED is OFF.
► 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).

► Confirm that the amber LED is OFF. If the amber LED is ON, turn the sensitivity control anti-
clockwise until the amber LED is OFF.
► Remove the board.
► Position the board back on the rail system, as in Step 1, and confirm that the amber LED is
ON.
► If the board has holes or cut-outs, go to continue at next Step. If the board has no holes or
cut-outs remove the board from the rails and confirm that the amber LED is OFF.
► 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.
► If the LED flickers when encountering holes or cut-outs, turn the sensitivity control clockwise a
further quarter turn.
► Repeat previous two Steps until the correct setting is achieved.
► Remove the board from the rails and confirm that the amber LED is OFF.
► On completion of adjustment, refit the top safety cover removed previously.

► Remove the top safety cover.
► Ensure that there is no board on the rails or objects near the sensor.
► Press and hold the yellow SET button (1) on the sensor until the status LED (2) flashes green
(approximately 2 seconds).
NOTE
Ensure that use of the Set button (1) is not approached from above the sensor to avoid the sensor
detecting hand movement.
