4.5.17.1
4.5.17.1 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.
