Removal
NOTICE
Short and long nozzle changer
The procedure for removal and installation is the same for the short and long nozzle
changer.
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation.
1.2 "Preparatory work..." [}16]
► Switch off the compressed air supply
5.2 "Disabling the compressed air supply" [}86]
► Remove all magazines.
► Remove the four fastening screws.
► Unplug the nozzles changer from all electrical and pneumatic connections. You might like to
mark their positions to make clear assignment easier later on.
► Take care not to lose the support plates. Remember their exact positions, as they will need to
be returned to these original positions, during assembly.
► Carefully lift the nozzle changer out of the machine.
Installation
Follow the removal instructions in reverse order for installation. Also observe the following instruc-
tions:
► If present: check the jumper on the nozzle changer.
2.8.6 "Jumpers on the Nozzle Changer" [}44]
► Re-insert the support plates.
► Check the mechanical installation height of the nozzle changer.

2.8.4 Setting the Nozzle Reject and Station Height
Parts, equipment and tools
●
Depth measuring gauge (300mm) [03079617-xx]
●
Shim plates for nozzle reject device [03039514-xx]
●
Screws DIN 7991-M4 x 20-8.8 [00333782-xx]

Plastic sheet (to keep the depth measuring gauge away from the magnets)
Setting
Fig.37: Measurement
1. Position upper edge of measuring scale
on the linear guidance
2. Bottom end of measuring gauge on the
assembly surface of the nozzle station
► Push the placement head to be meas-
ured outwards.
► Place a plastic plate in front of the mag-
nets.
► Position the measuring gauge on the
upper edge of the nozzle station
assembly surface and measure the dis-
tance to the upper edge of the lower X
axis linear guidance.
CAUTION!
Hold the measuring scale vertically!

1. Measuring scale
2. Top edge of the X axis lower linear
guide
3. Values to be set (150 +/- 0.2 mm)
4. Nozzle changer contact surface
Setting
► During the following inside measurement make sure that the tip of the measuring scale does
not touch the magnetic strip as this might scratch it!
CAUTION
Strong magnetic forces
Place a suitable plastic plate between the magnet and measuring scale.
► Position the measuring scale (1) on the top edge of the X axis lower linear guide (2) and
measure the distance to the nozzle changer contact surface (4)
.
► Hold the measuring scale vertically (1).
► The setting value (4) is 150+/‑0.2mm
.You can adjust the height, where necessary, by removing or adding NC shim plates.
CAUTION
Crash hazard!
Do not place too many shim plates underneath.
► Repeat this measurement on the inside of the gantry (5).
► Calibrate the position of the nozzle changer.
