3.17.1 Adjusting the Star to the Star's Magnetic Neutral Position Replacing the Star
Service Manual SIPLACE Placement Heads DLM3/DLM4 53
Installation
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.
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.
Further installation is performed by following the above instructions in the reverse order.
3.17.1
3.17.1 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.
If both of these conditions are fulfilled, the star has been fitted correctly.
NOTICE
Sleeves
Remove any remaining sleeves before fitting the star.
Wear laboratory gloves when you remove the sleeves from the star.
NOTICE
Do not trap the hoses
Make sure that the vacuum hoses of the segments are not pinched.
NOTICE
You may need to slightly grease the valve plunger
Grease the sealing lips economically with the greasing tool or with a lint-free cloth coated with
ISOFLEX TOPAS NCA 52.
Read the relevant section of the maintenance manual for your machine.
