9.16.4 Installing the turning station
●
Clean the O-ring (see item 8 in Fig. 9.16.1) with ethyl alcohol.
●
Lightly grease the teeth of the toothed lever (see item 7 in Fig. 9.16.1) with Unimoly GL82.
●
Carefully push the amplifier board through the countersinking in the encoder housing.
●
Carefully insert the turning station. Be particularly careful to ensure that the connector contacts on the
’Turn nozzle’ conversion board (see item 9 in Fig. 9.16.1) are seated correctly in slot X8 or X9 on the
’Head’ conversion board Y0303 (see item 5 or 6 in Fig. 9.16.2).
CAUTION
O
You MUST ensure that the connector contacts on the ’Turn nozzle’ conversion board are aligned with the
contacts of connector X8 or X9. Otherwise there is a risk of short-circuit.
●
Connect the plug of the amplifier board to slot X12 or X13.
●
Fix the amplifier board in place.
●
Fix the turning station using the two hexagon socket-head screws.
●
Place a segment on the star and turn it towards the appropriate turning station.
●
Carefully pivot the turning station in towards the segment.
Ensure that the optical scanning unit of the turning station slides into the scale disk of the segment without
touching the disk.
●
Fit the housing cover and encoder housing as described in section 9.14, page 107 and 9.13, page 103.
9.16.5 Adjustments
●
Check the dynamic behavior of the dp1- or dp2 axis using the adjustment instructions.
●
Use the SITEST program to check that the station is functioning correctly.
9.16.6 Replacing the combined DC motor / tacho (drive motor)
●
Remove the drive O-ring (see item 2 in Fig. 9.16.3).
●
Mark the connecting wires of the motor and tacho (see item 1 in Fig. 9.16.3) and solder the wires.
●
Loosen the three M1.6 countersunk head screws for fixing the drive motor (see item 4 in Fig. 9.16.3).
●
Replace the drive motor and fix the new drive motor.
●
Pull new heat-shrink sleeves over the motor and tacho connecting wires.
●
Solder on the connecting wires and carefully shrink the heat-shrink sleeves.
●
Clean the drive O-ring with ethyl alcohol.
●
Pull on the drive O-ring. Be careful not to stretch it.
●
After assembly, check the dynamic behavior and functioning of the turning station with reference to the
adjustment instructions or using the SITEST program.

9.16.7 Replacing the drive O-ring
Dynamic behavior problems with the drive can be caused by a loss of O-ring tension.
●
Replace the O-ring.
●
Clean the new O-ring with ethyl alcohol. Be careful not to stretch the O-ring when you fit it.
●
After installation, check the dynamic behavior and functioning of the turning station with reference to the
adjustment instructions or using the SITEST program.
