2) Nozzle_Select_Pos.Z

* Because B1 and C1 types have UP limit stoppers, adjust so that no contact is made with the

stopper before beginning this measurement.

1. After completing all the Nozzle_Select_Pos.X,Y measurements, remove the receiver jig

from the changer and the nozzle jig from the nozzle shaft. Also raise the nozzle station.

2. Mount a nozzle on the nozzle shaft and move the head by hand to the first

Nozzle_Select_Pos.X,Y position of the single nozzle station.

3. Turn the Z-axis pulley by hand to lower the nozzle to the position shown below. This is

the Nozzle_Select_Pos.Z position.

1) For types other than C1 and B1:

•3.5mm spline type : Raise to a position 3666 pulses above the Z-axis Min. Limit.

•2.0mm spline type : Raise to a position 3000 pulses above the Z-axis Min. Limit.

2) For B1 and C1 types:

•3.5mm spline type : Raise to a position 4083 pulses above the Z-axis Min. Limit.

•2.0mm spline type : Raise to a position 3416 pulses above the Z-axis Min. Limit.

* Note that the UP limit for B1 and C1 types is slightly lower due to the stopper adjustment

which is required (see step 5). Therefore, lower the Z-axis and re-measure the

Nozzle_Select_Pos.Z position.

4. Execute the following command sequence to automatically enter the data: [NZZLE

SELECT] à [Zn] à [SET].

5. With the Z-axis at the step 3 position (see above), adjust so that the bottom of the nozzle

disk makes contact with top surface of the nozzle station. Set a dial gauge on the top face

of the nozzle disk and find the exact height at which contact is made with the top face of

the nozzle holder.

* If measuring with a dial gauge, be sure that the gauge is calibrated.

* After adjusting types B1 and C1 as described above, position the UP limit stopper against the

bracket, then turn the stopper another 1/2 a revolution in the bracket direction and lock it there.

6. With the changer raised, adjust the UP limit sensor. Begin by moving the sensor upward

until it switches off, then lower the sensor to the position where it switches on. Secure the

sensor 1mm below that position. Adjust the DOWN limit sensor by moving it downward

until it switches off, then raise it to the position where it switches on. Secure the sensor

1mm above that position.

7. Finally, verify that all nozzle detection sensors are operating properly. Both the green and

red LEDs should be lit when a nozzle is absent. If a nozzle is present, only the green LED

should be lit. Also use I/O commands to verify that inputs are correct.

Nozzle_Check_Pos.X,Y,Z (Single Types Only)

Note: As shown in the figure below, the slits are sandwiched between the sensor and sensor

bracket. Mount so that the sensor emitter and receptor are directly opposite (on a

straight line) the slits (sensor beam aligned). This can be gauged by eye.

1) Mount a 10mm front light nozzle on the single shaft.

2) Turn on the “OUT Y018 NZL CHNGR UP” I/O to raise the nozzle changer unit.

3) Move each axis to the prescribed position and lock the servos.

X-axis: Move the nozzle tip midway (centered) between the nozzle check sensors.

Y-axis: While watching the “IN X00D NOZZLE CHECK” I/O, use the Y-axis

inching button to retract the nozzle. Retract the Y-axis 2000 pulses

beyond the point where the I/O switches ON. (2000P1s = 5mm: nozzle

center)

Z-axis: While watching the “IN X00D NOZZLE CHECK” I/O, use the Z-axis

inching button to lower the nozzle. Lower the Z-axis 1000 pulses beyond

the point where the I/O switches ON. (1000P1s = 1.5mm)

4) After moving each axis to its prescribed position, execute the following command sequence

to automatically enter the data:

[NZZLE SELECT] à [Check Pos.] à [SET].

[6-21] Nozzle_Diameter Check, Adjustment (Single Types Only)

1) After completing the [7-20] adjustment, adjust the sensitivity

of the nozzle sensor amplifier using the following 4 nozzle sizes: 0.7, 1.3, 10, 20.

2) Begin by increasing the amplifier sensitivity until the sensor beam from the emitter side is

received by the receptor side. (The green LED lights when the sensor beam is received.) If the

sensor beam is not received even when the sensitivity is increased, adjust the sensor and slit

positions until the sensor beam is received.

3) Verify that the 4 nozzle types listed above are present at the nozzle changer.

(The “NOZZLE TYPE” item must be “1”.)

[Nozzle data settings in program]

Module/Head# à Enter the module number.

Nozzle No. à Enter the nozzle number.

Size X à Enter the nozzle diameters.

Size Y à Enter the nozzle diameters.

BackLight Size X à 300

BackLight Size Y à 300

Nozzle Type à 1

Nozzle Length à 0

4) Begin by performing a nozzle change in order to mount a 10mm nozzle at the head.
