Q & A

4.1.1 Adjusting the low-liquid sensor (angle setting)

Press the emergency stop button.

The machine must be in emergency stop to ensure safety during work.

Check the amp signal output setting.

Set the amp output selector switch to the “L_ON” side so that the low-liquid sensor stays on when it is

detecting the dispensing liquid in the syringe.

TIP

This function can be used with either “D_ON” or “L_ON” setting. But in most cases, set the amp output selector switch

to “D_ON” when detecting the piston.

Adjust the low-liquid sensor level.

1. Set the empty syringe into the head section.

2. Check that the sensor optical axis is along the piston detection position in the used syringe.

3. Allow the sensor beam to strike the syringe.

The holder in which the syringe is set contains 4 openings. Rotate the R-axis so that the sensor faces

the opening where the highest value is obtained.

NOTE

If the sensor height needs to be adjusted, loosen the two bolts holding the sensor bracket and slide the sensor up or

down.

4. Press the Auto SET button on the amp and check that the calibration indicator is lit up.

Q & A

Adjust the sensor level when the liquid still remains.

1. Set the syringe full of liquid into the head assembly.

CAUTION

If the product label afﬁxed to the syringe is large so that it covers the lower part of the syringe, peel it off from the lower

half of the syringe.

If the product label covers the lower part of the syringe, the low-liquid sensor cannot detect whether adhesive has run

out or not.

2. Allow the sensor beam to strike the syringe.

The holder in which the syringe is set contains 4 openings. Rotate the R-axis so that the sensor faces

the opening where the lowest value is obtained.

3. Press the Auto SET button on the amp and check that the calibration indicator turns off.

Check the sensor ON/OFF operation.

1. Open the [Unit]-[I/O] tab.

2. Move the piston of the empty syringe up and down across the sensor optical axis, and check that

the I/O monitor for the sensor switches as follows.

Head 1 :N1301001

Head 2 :N1301002

Head 3 :N1301003

When liquid is detected (liquid remains) :1

When no liquid is detected (no liquid remains) :0

Sensor ON/OFF check

Check here.

NOTE

• When using the low-liquid sensor, set the maximum liquid amount for the dot station to "0".

Q & A

4.1.2 Making the settings

Use the following procedure to make the settings.

Enter the detection angle.

In the VmSpec window that appears with the [Machine] button, open “Setting” – “Mechanical” –

“Position” and enter the angle in “Wait Point – R (deg)”. In most cases, enter “-114” deg. (The remaining

liquid amount will be detected at angles of -114, -24, 66, and 156.)

Entering the detection angle

Enter detection angle.

64302-N7-00

NOTE

If the remaining liquid amount cannot be detected correctly with the “-114” setting, check to ﬁnd the angle that

allows correct detection.

Rotate the R-axis by hand to align it with the position where all sensors can detect the remaining liquid. Then open the

[Unit] – [Head] – [Move Axis] screen, check the R-axis coordinate displayed on the [ZR] tab, and enter it as the

detection angle.

Set the detection method.

In the VmSpec window, open “Setting” – “Mechanical” – “Position” and set “Fluid Check Type” to

“Angle”.

Setting the detection method

Set to “Angle”.
