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).
