WARNING
• Turn off the 200 V servo power before carrying out this work.
• Exercise extreme caution when working on the machine if the cam is
not at its origin (0 deg.). Recoil of the cam axis can endanger the
operator.
This sensor checks whether or not the clutch is correctly engaged when fine theta reverse
and/or nozzle origin positioning is performed. Check that the sensor LED (red) is OFF
when the clutch is correctly engaged and ON when the clutch is not correctly engaged.
Set the amp volume so that it operates as shown in the following figure. Refer to
“Nozzle Detection Sensor”of 3.9 “Station 17” of this chapter for the adjustment method.

3.7 Station 13
Pre-theta Reverse Mechanism
At station 13, reverse rotation is performed so that the nozzle is returned to the rotation
angle that existed at station 3.
3.7.1 Clutch Engage Check
WARNING
• Turn off the 200 V servo power before carrying out this work.
• Exercise extreme caution when working on the machine if the cam is
not at its origin (0 deg.). Recoil of the cam axis can endanger the
operator.
Perform this check on the low-pressure nozzle.
1. With the cam at 0°, operate the lever by switching ON the solenoid stopper (Y02C
PRQ ROT SOL ON).
2. Set the dial gage on the under side of the nozzle shaft brake.
3. Turn the cam to 200° using the handle.
4. Confirm that the clutch is correctly engaged and that the nozzle has lowered
0.30~0.35 mm.
Note: The low-pressure nozzle refers to the nozzle axis (out of the 20) that receives the weakest
pushing pressure. Use the low-pressure nozzle for meshing checks at stations 3, 5, 10, 12
and 13.

3.8 Station 16
Nozzle Vacuum Valve Off
Station 16 uses the mechanical valve to shut off the vacuum in the nozzle.
Nozzles can no longer hold parts once the vacuum is cut.
Ensure that station 16 discards the parts that fail vision processing.
3.8.1 Nozzle Vacuum Valve Lever Height Adjustment
1. Press the EMERGENCY STOP button to take the 200V down to 100V.
WARNING
• Turn off the 200 V servo power before carrying out this work.
• Exercise extreme caution when working on the machine if the cam is
not at its origin (0 deg.). Recoil of the cam axis can endanger the
operator.
2. Move the reference head to station 16.
3. Use the cam handle to rotate the cam to 203°.
4. Ensure that there is a 0.05 ~ 0.1 mm space under the nozzle vacuum valve.
