Basic operation
4. Basic tasks for optional units
4.1 Low-liquid sensor
When the dispensing liquid inside the syringe is low, the low-liquid sensor detects it and issues a warning.
The low-liquid sensor consists of a sensor head and an amp section. The sensor head is installed at the side
of the nozzle mounting section, while the amp section is installed on the top of the dispenser head assembly.
The low-liquid sensor must be readjusted after changing the type of liquid or after replacing the low-liquid
sensor itself.
c
CAUTION
Prepare a used (empty) syringe and a syringe full of liquid before starting adjustment. Accurate adjustment will not be
possible if only an empty syringe is used.

CAUTION
• The sensor may fail to detect whether the liquid has run out or not, depending on the liquid type and how the
piston scrapes the liquid .
• If the product label is affixed to a position that can be seen from the holder opening, the sensor may not detect
whether the liquid has run out or not.

Basic operation
4.1.1 Adjusting the low-liquid sensor
e
1
Press the emergency stop button.
The machine must be in emergency stop to ensure safety during work.
2
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.

Adjust the low-liquid sensor level.
1. Set the empty syringe into the head section.
2. Check that the optical axis of the sensor is at a position 5 mm above the piston in the 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.
n
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.
