[5-3] Mounting Shafts For Single Nozzles
* Note that the inner spring used in systems with placing pressure control is different from the
standard item.
1) Verify that there is a 2mm gap between collars. If the gap is other than 2mm, request
instructions from the supervisor.
2) In the same manner as for index holders, mount the single holder in the prescribed direction (note
positioning pin) using the M5 x 12mm machine screws and spring washers.
[5-4] Measuring the Single Shaft Swing
Set a dial gauge at the bottom of the single shaft and measure the shaft swing.
(This measurement is not required for index nozzles.)
Tolerance: 0.1 / 360degrees
[5-5] Adjusting the Pressure Control Sensor
1) Mount a standard nozzle on the head.
2) Clamp a standard PCB on the main conveyor.
3) Move the nozzle to the PCB surface and lower the Z-axis to the position specified by the Z0 Proper
data value.
4) Loosen the hollow bolt which secures the sensor and adjust the sensor position so that there is a
0.3mm gap between the shaft collar's side face and the sensor's side face.
5) Adjust the bracket position up and down until the pressure control sensor switches on when the
Z-axis is lowered 0.15 ± 0.015mm (100 ± 10 Pls) from Z0.

[5-6] Attaching the Single Nozzle Q-Cover
Mount the single nozzle Q-cover on the bottom of the placing head using the M3 x 5 bolts and spring
washers.
[5-7] Measuring the Nozzle Vacuum Pressure
1) Mount a 2.5mm nozzle at the holder and shaft.
2) Attach a vacuum gauge to the end of the nozzle, then switch on the "Y002 NOZZLE VACUUM"
I/O at the relevant module and measure the vacuum pressure.
3) Verify that the vacuum pressure is – 79.8kPa ( – 600 mmHg) or less at each module.
4) Switch on the "Y003 NOZZLE BLOW" I/O to break the vacuum. Adjust the vacuum break
pressure adjusting screw on the solenoid valve (at top side of placing head) so that the measured
vacuum pressure is +6.65kPa ( +50mmHg).
Adjust this bracket up
and down until the
sensor switches on at
0.15 ~ 0.015.

[5-8] Lighting Unit Operation Check
* Execute I/O commands to enable early detection of incorrect mounting conditions and operation
problems.
* At 2-camera systems, turn the "Y008 CAMERA CHG1,2" I/O on and off to switch between cameras
1 and 2.
X : Camera1 O : Camera2
1) For camera types 2 and 3 (CCD cameras), with front lighting:
* Back lighting is always activated at power on. (Camera 1 uses only back lighting.)
Camera Type2 Camera Type 3
I/O “Y006 F.LIGHT 1” ON Black circle "B" lights, C White circle "B" lights, C
I/O “Y007 F.LIGHT 2” ON White circle "B" lights Black circle "B" lights
I/O “Y00B F.LIGHT B” ON "A" lights "A" lights
2) For camera type 4 (line scan camera), with front lighting:
When the "Y007 F.LIGHT 2" I/O is turned on, the top shutter closes and the halogen lamp shines
at 70%.
If the "Y006 F.LIGHT 1" I/O is turned on while the Y007 I/O is on, the bottom shutter opens and
the halogen lamp shines at full intensity.
* (The two shutters are located above the halogen lamp. The top shutter has a reflector plate and the
bottom shutter has a plate.)
The front light remains off if only the Y006 I/O is turned on.
The ring light turns on when the "Y00B F.LIGHT B" I/O is switched on.
* When the "Y006 F.LIGHT 1" I/O is turned on, the top shutter opens and the fiber light remains off.
When the "Y007 F.LIGHT 1" I/O is turned on, the bottom shutter opens and the fiber light shines
at 100% if "F.LIGHT 1" is on. If "F.LIGHT 1" is off, the fiber light brightness is reduced.
The ring light turns on when the "Y00B F.LIGHT B" I/O is switched on.
* After verifying that the dip switch is at the upper position (MANUAL), set the halogen lamp
adjusting volume to "1.8".
