4.4.17.1 Adjusting the Star to the Star's Magnetic Neutral Position
Adjusting the Star to the Star's Magnetic Neutral Position
When adjusting the star, the aim is to make sure the vertically aligned segment axis of segment No. 1
corresponds with the magnetic neutral position of the star stepping motor.
► To do this, fit the star zero point gauge and insert the gauge pin into the gauge for the star and into
segment no. 1, until it reaches the stop.
► Pull the motor line plug of the star motor off the slot on the intermediate distributor and connect the
motor line to the power supply.
► Connect the power supply unit to the mains power.
► Tighten the three M3x8 hexagon socket-head screws on the star and remove the gauge pin.
► To do this, reinsert the gauge pin into the star gauge and insert into the segment, until it reaches the
stop.
► Disconnect the power pack from the power source.
► Please check:
⇨ That the gauge pin can be inserted easily.
⇨ That the star does not rotate out of its current position as a result.
NOTICE!
Remove any remaining sleeves before fitting the star.
Wear laboratory gloves when you remove the sleeves
from the star.
► Push all the segments (6) slightly outwards.
► Insert small Allen keys (e.g. size 2) into the holes for
the star fastening screws (5).
► Hold the star over the star drive shaft (3), so that the
Allen keys slide into the threaded holes in the star
drive.
► Insert the star.
NOTICE!
Make sure that the vacuum hoses of the segments are
not pinched.
► Push all the segments inwards so that the segment
ball bearings slide into the raceway (7).
► Check that the star is seated flat on the drive shaft.
► Loosely tighten the three M3x8 hexagon socket-head
screws on the star so that the screws can still move
slightly in the fixing holes.

If both of these conditions are fulfilled, the star has been fitted correctly.
► Repeat the adjustment procedure if the gauge pin does not slide easily into the hole.
CAUTION
The power pack operating time is limited!
The maximum operating time of the power pack for the star motor is five minutes. Do NOT ex-
ceed this time. If you have to disconnect the power pack from the power source because it has
been operating for five minutes, always insert the gauge pin before switching the power pack
back on again.
1. Star drive, digital (DLM3, DLM4)
2. 4 x M5x16 hexagon socket-head screws
3. C&P head front part
► If you still can not fit the star in the magnetic neutral
position of the star motor, follow the instructions be-
low:
► Loosen the four M5x16 hexagon socket-head screws
(2) for fixing the star drive (1) and turn the star drive
in the direction that will allow the star to be adjusted
with respect to the magnetic neutral position.
► Tighten the four hexagon socket-head screws.
► Loosen the three M3x8 hexagon socket-head screws
(5) fixing the star again and repeat the adjustment
procedure.
NOTICE!
The star is correctly installed, if it does not turn out of po-
sition when the gauge pin is removed during zero current
star operation.
► Remove the gauge for the star.
► Insert the power cable plug connector for the star
drive into the slot on the intermediate distributor. The
plug connector is an anti-rotation connector.
► Fit the front part of the C&P head onto the back part
of the C&P head.
► Check the magnetic neutral position.

Removal
Installation
► Installation is performed by following the above instructions in the reverse order. Observe the follow-
ing points:
▪ Check that the white connection pieces are seated firmly on the segments. If these are loose, you
will need to replace the entire star.
▪ Make sure that there is an even space between the hoses:
NOTICE!
Do not remove the star!
For clarity, the diagram shows the star when removed
from the machine. However, you do not need to remove
the star to replace the air blast supply.
► Undo and remove the two screws fastening the air
blast supply (1).
► Fasten the air blast supply with the two screws pro-
vided.
► Dismantle the star from the C&P head.
► Remove the sleeve from the segment of the defective
hose.
► Undo and remove the two screws fastening the air
blast supply (1).
► Disconnect the hose (3) from the segment (1).
► Now pull the valve (2) out of the star.
CAUTION!
O-ring
There is an O-ring behind the valve. Make sure that you
do not lose this and that you fit it again during installation!
► Disconnect the hose from the valve.
