4.21 ST1 NZ Pick-Up Position Adjustment
1. Set the cam to 0 degrees and turn ON the ST1 nozzle UP/DOWN solenoid valve. (Y031)
2. Place the 1
st
nozzle height calibration jig on the D-axis pallet and install the
nozzle jig at nozzle holder No.1. Set the cam angle at 170 degrees and move the
NZ-axis manually so the nozzle jig descends until the pick up height is 0.65mm (at this
condition the dial gauge should read 0).

IMPORTANT!!
The pick-up height calibration is critically
important to ensuring stable pick-up. If
not adjusted correctly, damage to
components may occur (due to shock
from nozzle) or pick-up rates will not be
at optimum levels. Be sure to use care
when making adjustments in this area.

3. Calibrate the NZ-axis servo counter value for all shafts (A through P) and record the value.
4. Calculate the average value for all shafts and set as the : PICK UP POS NZ.
Press: [Maintenance] → [Calibration] → [Pick Up Reference] → [NZ Original Pos.] → [Set]
*Measurements should be carried out at device locations (2 & 29, CP-732/733E), (2 &
39, CP- 742/743ME), (2 & 69, CP-742/743E) on both pallets.

4.22 Station 9 Mechanical Valve Adjustment Check
1. Remove the spool valve from shaft “A “and install the valve alignment jig.
Mechanical Valve Jig
Jig No. DGPJ6610
Note:
Place the dial gauge on the right side of the
“Low Valve” and set to 0. Remove the valve
and install the alignment jig at the same
position the valve was located. All valves
should be within 0.1mm of each other.
Refer to Sec. 3.16, page 3-32 step 6.

2. With the cam at 0 degrees turn the 9
th
station place solenoid OFF. (Y034)
3. Disconnect the air.
4. Move the cam angle to 195 degrees.
5. Loosen the forward and backward positioning bolts for the 9
th
station bracket.
6. Adjust the 9
th
station bracket so that the small round bracket notch goes directly into the jig hole.
You can check if it is properly inserted by moving the bracket. If it is completely inside, the
bracket will not move.

7. Once finished, remove the jig and reconnect the air at 0 degrees.
8. Turn the 9
th
station place solenoid ON (Y035) and install the spool valve on shaft A. Ensure the
spool valve is in the same position as the spool valve on the B shaft. (use the X-axis pulse
counter with the cam at 195 degrees and measure using a dial gauge.

9. Next, bring the shaft with the lowest spool to the 9
th
station at 195 degrees.
10. Set the gap between the spool and bracket to 0.1mm using a feeler gauge ( figure 36 above).
11. Set the flow controller as follows: For the rough adjustment of the flow controller, set 5 turns
from fully closed. For fine adjustment, set the cam at 195 degrees with the
highest valve at
station 9. Turn ON (I/O: Y03A Air Blow) Using a manometer, set the air pressure to 113+/-
3mmHg. (15.0+/-0.5 kPa)
4.23 Station 1 Mechanical Valve Adjustment
1. Adjust all shafts so that the gap between the spring pin BKT (1) top surface and support BKT
top surface is 2.3mm. (A) Note: all spring pin heights should be within 0.1mm of each other.

The spring pin height on shafts
A to P should be within 0.1mm.
2. Set the mechanical valve switch lever alignment as follows:
a. Adjust the clearance between the spring pin bracket and lever bracket using a 12mm
spacer jig. (figure 38). (Jig. No. ADCPJ8150)
b. Align the vacuum switching lever and mechanical valve as illustrated with the cam at 170
degrees. (figure 39).
