3.4 Adjusting the conveyor unit setup
When the board type to be produced is changed, the conveyor unit setup must be adjusted, and the feeders
prepared to match that board type. This section describes how to change the conveyor unit setup.
Board clamping method
Select "Edge Clamp" for the board clamping method. This method clamps a board by pushing up its edges against the
board hold plates. Push-up pins are also used to support the board at points other than its edges.

Place the push-up pins in the correct positions on the push-up plate.
Push-up pins are attached on the push-up plate by magnet. Considering the shape and size of the
board, place the push-up pins on the push-up plate so that they uniformly support the board, including
the edge of the board.

Set the push-up pins in positions where they will not interfere with the conveyor rails and other parts when the push-up
plate is raised.

Raise the push-up plate.
Check safety and press the [Push Up] button on the Setup screen. The push-up plate moves up to clamp
the board.

Check that the board is uniformly clamped on the conveyor.
Lightly tap on the board and also check for warping of the board from the side. If the board is
supported
evenly with no warping, the adjustment is okay.
TIP
It may be convenient to mark the positions of the push-up pins on the plate (with a label, magic marker, etc.) for each
board type.

Remove the board from the conveyor.
Press the [Push Up] button on the Setup screen to lower the push-up plate and then remove the board.
