Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The
exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks.
When these symbols appear in the body of this manual or on warning labels, refer back to these Warnings.
Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this
manual where applicable.
WARNING
TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or
swallowed.
• Read Safety Data Sheets (SDSs) to know the specific hazards of the fluids you are using.
• Route exhaust away from work area. If diaphragm ruptures, fluid may be exhausted into the air.
• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury, including
eye injury, hearing loss, inhalation of toxic fumes, and burns. Protective equipment includes but is not
limited to:
• Protective eyewear, and hearing protection.
• Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. Paint or
solvent flowing through the equipment can cause static sparking. To help prevent fire and explosion:
• Use equipment only in well-ventilated area.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop
cloths (potential static sparking).
• Ground all equipment in the work area. See Grounding instructions.
• Never spray or flush solvent at high pressure.
• Keep work area free of debris, including solvent, rags and gasoline.
• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes
are present.
• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when triggering into pail. Do not use pail liners unless they
are anti-static or conductive.
•Stop operation immediately if static sparking occurs or you feel a shock. Do not use equipment until
you identify and correct the problem.
• Keep a working fire extinguisher in the work area.
ELECTRIC SHOCK HAZARD
This equipment must be grounded. Improper grounding, setup, or usage of the system can cause
electric shock.
• Turn off and disconnect power at main switch before disconnecting any cables and before servicing
or installing equipment.
• Connect only to grounded power source.
• All electrical wiring must be done by a qualified electrician and comply with all local codes and
regulations.

PRESSURIZED EQUIPMENT HAZARD
Fluid from the equipment, leaks, or ruptured components can splash in the eyes or on skin and cause
serious injury.
• Follow the Pressure Relief Procedure when you stop spraying/dispensing and before cleaning,
checking, or servicing equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Specifications in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical
Specifications in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For
complete information about your material, request Safety Data Sheets (SDSs) from distributor or
retailer.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine
manufacturer’s replacement parts only.
• Do not alter or modify equipment. Alterations or modifications may void agency approvals and create
safety hazards.
• Make sure all equipment is rated and approved for the environment in which you are using it.
• Use equipment only for its intended purpose. Call your distributor for information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not kink or over bend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
PLASTIC PARTS CLEANING SOLVENT HAZARD
Many cleaning solvents can degrade plastic parts and cause them to fail, which could cause serious
injury or property damage.
• Use only compatible solvents to clean plastic structural or pressure-containing parts.
•See Technical Specifications in all equipment manuals for materials of construction. Consult the
solvent manufacturer for information and recommendations about compatibility.

Grounding
Grounding plug: this product is equipped with a cord
having a grounding wire with an appropriate grounding
plug. The plug must be plugged into an outlet that is
properly installed and grounded in accordance with all
local codes and ordinances.
Hard-wires units: ground wire must be used.All
electrical wiring must be done by a qualified electrician
and comply with all local codes and regulations.
Air and fluid hoses: use only electrically conductive
hoses to ensure grounding continuity.
Fluid supply container: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive
surface, such as paper or cardboard, which interrupts
grounding continuity.
Setup and Startup
1. Use cable to connect remote I/O, sensor, servo
motor and Control Box correctly.
2. Connect power line and Control Box.
3. Adjust the pressure regulating valve so that the air
pressure provided by the customer is at least 80 psi
(0.6 MPa, 6 bar), and no higher than 100 psi (0.7
MPa, 7 bar).
4. Press “Power” button.
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.

Automatic operation main
screen
When the control box is powered on, the system
automatically enter into the main screen of automatic
operation.
1. Control mode selection
• Shot mode: the system according to the selected
style of the specified dispensing volume and flow
rate, to complete the dispensing. In this mode, the
master station only needs to send out the start
signal of more than 200 ms, and the system
automatically starts to dispense, and automatically
closes the dispense valve after completing the
target dispensing volume.
• Bead mode: the system according to the selected
style of the specified dispensing flow rate, to
complete the dispensing. In this mode, the master
station needs to maintain the start signal until the
dispensing is completed.
Note: The operating mode cannot be switched during
the dispensing process of the system.
2. Style settings and specified shot size and shot rate
• The style setting modes includes two modes:
external signal control mode and local operation
panel control mode. The style setting mode is
specified in the advanced settings of the parameter
setting screen.The system provides 0-7, a total of 8
groups of style settings. The external control system
or the operator can choose different style settings
according to the process requirements.
• The system will display the shot size and shot rate
of the selected style in this area.
3. Progress bar and actual dispense volume
• Shot mode: the progress bar displays the
completion of the current target, and displays the
current dispensing volume.
• Bead mode: the progress bar always displays
100%. The current dispensing volume is the same
as the target dispensing volume.
4. Current status display
• Standby means that the system is not doing any
work, there is no failure or alarm.
• In dispense means that the system is in the process
of dispensing.
• In reload means that the system is in the process of
reloading.
• In purge means that the system is in the process of
purging.
5. ‘Home’ button
Return to the Home point command button. When this
button is pressed, the system must be inactive.After
pressing the button to start the Home operation, the
button will blink until the rod returns to the Home point,
and then the button will remain on until the next
operation is started.
6. ‘Extend’ button
The Extend operation is used to immerse the metering
rod fully into the chamber before the system stops in
use for a long time.The Extend button operates basically
the same as the Home button.
