2b. Transfer position of the Tower 2 WTC

When you press the button to calibrate the Transfer position the tray moves out and stops approx.

5mm before the feed axis end.

 Then move the tray in the direction to the machine and stop so that the plastic edge comes into

line with outer edge of the frame from the feed axis. You must do this in one step, because that

you eliminate the tolerance between the space and the driver and you don‘t need a pick up

offset for the tray.

During the production the trays move a different way to her pick up position but the Y Position of

the machinen (pick up postion) of both trays is the same.

Attention:

and pick up position for the twin head.

The transfer position of tower 1 is situated a few millimeters further than the end of the feed axis,

of tower 2 it is situated a few millimeters before the end of the feed axis.This offset is automatically

calculated and adjusted.
