3.2.5 Dip stroke plate
1. Electromagnets
2. Permanent magnets
3. Dip stroke plate
The dip plate is held in place on the dip stroke plate by four permanent magnets. Two electromag-
nets are used for additional fixing and check whether a dip plate is fitted. The electromagnets de-
tect changes in the distance between dip plate and lift unit. This will be the case when the dip plate
gets stuck to the park plate during the downwards movement.
3.2.6 Axes
The LDU has two drive axes.
The squeegee axis moves the squeegee forwards and backwards.
1. Squeegee
2. Front bearing block
3. Spindle
4. Guide rail
5. Rear bearing block
6. Coupling
7. Motor
The lift axis moves the dip plate up and down:
1. Motor
2. Coupling
3. Dip plate
4. Dip stroke plate
5. Guidance
6. Slide
7. Bearing block (base of park plate)
The maximum lift of the lift axis is -8.5mm to +22mm (mechanical stoppers). The basic position
(determined by an inductive switch) is at -7.5mm. The squeegee is positioned at 0mm. The dip
position is at +17.5mm. Squeegee and dip position are determined by the pulse generator of the
motor.

3.2.7 Leveling device
The leveling device is based on a three-point support: one bearing ball and two adjustment screws.
The front bearing block is located on the bearing ball and the front adjustment screw. The rear
bearing block is located on the rear adjustment screw.
