Installation
4.5.17.1 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.
X 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.
X 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.
X Connect the power supply unit to the mains power.
X Tighten the three M3x8 hexagon socket-head screws on the star and remove the gauge pin.
X To do this, reinsert the gauge pin into the star gauge and insert into the segment, until it reaches the
stop.
X Disconnect the power pack from the power source.
X Please check:
That the gauge pin can be inserted easily.
That the star does not rotate out of its current position as a result.
If both of these conditions are fulfilled, the star has been fitted correctly.
X Repeat the adjustment procedure if the gauge pin does not slide easily into the hole.
NOTE:
X Remove any remaining sleeves
before fitting the star.
X Wear laboratory gloves when you
remove the sleeves from the star.
X Push all the segments (6) slightly outwards.
X Insert small Allen keys (e.g. size 2) into the
holes for the star fastening screws (5).
X Hold the star over the star drive shaft (3), so
that the Allen keys slide into the threaded
holes in the star drive.
X Insert the star.
NOTE:
Make sure that the vacuum hoses of
the segments are not pinched.
X Push all the segments inwards so that the
segment ball bearings slide into the raceway
(7).
X Check that the star is seated flat on the drive
shaft.
X Loosely tighten the three M3x8 hexagon
socket-head screws on the star so that the
screws can still move slightly in the fixing
holes.
