8.5 PICKUP SCREW DEPTH SETTING

The depth that the Pickup screws thread into the board is adjustable. Depth is set at ¾" engagement at the

factory. A switch on the Pressure Pad is set to trip at the correct depth and shut the screw motor off. See

the instructions and picture below for the adjustment procedure.

1. Measure the overall length of the screw extending below the collet nut and record.

2. Pick up a board with the machine using the Manual screen.

3. E-stop the system before entering the Hazardous Zone.

4. Measure the distance from the top of the board to the bottom of the collet nut and subtract this

from the previous measurement. The difference is the current engagement depth. Loosen the

locknut and thread the trigger screw clockwise to increase the engagement depth or clock-wise to

decrease.

5. Re-tighten the locknut and retest the engagement depth.

A misaligned Light Curtain may cause random E-stops or prevent the system from operating altogether. Use the

following procedure to correctly set the alignment. The green LED on the receiver (sensor closest to the

Operators console) is steadily lit when the alignment is satisfactory. Amber or red LED's on the Receiver indicate

an improperly aligned Light Curtain. A green LED on the Emitter end of the Light Curtain shows only that power

is present. The Emitter is equipped a special Laser alignment system to help align it to the Receiver.

1. Depress the E-stop button with the system powered up. Do not enable the system.

2. Locate the small magnet that was shipped with WoodRunner. This is used to turn on the Laser alignment

beams on the Light Curtain Emitter. Pass the magnet over the bottom portion of the front face of the

Emitter as shown in the picture. This can take a few seconds and the 3 Laser beams will illuminate. Use

the top and bottom bracket adjustments to aim the laser beams at the Receiver windows. They do not

have to be perfect- just close is fine. Tighten the Emitter adjustment screws.
