Clutch Meshing Check Sensor Position Adjustment
1 Press the EMERGENCY STOP button to take the 200V down to 100V.
2 Use the cam handle to rotate the cam to 200°.
3 Use the inching keys to align the RQ-axis with the RQ-data position.
4 Make sure the clutches engage properly. Adjust the height of Bracket A so that
Gap C in the figure is 0.2 mm.
5 At this position, adjust the position of Bracket B so that the sensor beam enters
the hole on the dog.
WARNING
• Press EMERGENCY STOP before performing this procedure.
• Exercise extreme caution when working on the machine if the cam
is not at its origin (0 deg.). Spring recoil can rotate the cam inde-
pendently.

Clutch Meshing Check Sensor Amp Adjustment
Adjust the sensor amplifier so that it switches off when the clutches mesh properly
and on when the clutches do not mesh properly, pushing the sensor dog down.
Remove the cover of the amplifier and follow the procedure below.
Note: Be careful not to drop the cover inside the machine.
1 Set the bottom right switch to “L ON”.
2 Set the mode selector switch to “SET”. The digital display will then indicate “1”.
3 With the clutch engagement sensor on (sensor is detecting the hole in the dog),
press the [TUNING] button. The digital display will then indicate “2”.
4 With the clutch engagement sensor off (sensor is not detecting the hole in the
dog), press the [TUNING] button. The digital display will then indicate “9”.
5 Set the mode selector switch to “RUN”.
6 After completing the amplifier setting procedure, verify that the digital display
indicates 0 ~ 1 when the sensor is on, and 8 ~ 9 at all other times.

7.1.12 Mechanical Valve Switching (ST13)
Point
The station 13 mechanical valve is used to switch the nozzle vacuum off. The part is
released when the nozzle vacuum can no longer hold a part. Verify that parts that fail
vision processing are discarded at station 13.
Valve Switching Unit Position Adjustment
This adjustment should be performed on the low valve shaft after completing adjustments to the
vertical movement of the nozzle. (Refer to 7.1.9 “Nozzle Vertical Movement During Placement”
for details.) The low valve shaft can be identified by measuring the lower surface of the mechanical
valve spool on all shafts. Raise the spools and measure with a dial gauge, as shown in the diagram
below.
