A
DANGER OF HIGH PRESSURE FLUID INJECTION
The high pressure fluid that comes out of the spray gun or from any leaks may penetrate the skin and cause lacerations.
To prevent fire or fluid injection:
- Enable the spray gun's trigger safety lock when not spraying.
- Do not place hands or fingers on the nozzle of the spray gun. Do not try and stop leaks with your hands, body or
other.
- Do not point the spray gun towards yourself or anyone else.
- Do not spray without the special nozzle guard.
- Discharge the pressure of the system after spraying and before performing any maintenance operations.
- Do not use components whose operating pressure is less than the maximum pressure of the system.
- Do not allow children to use this machine.
- Be careful of the possible backlash when you pull the spray gun trigger.
If the high pressure fluid penetrates the skin, the wound may seem like a "simple
cut" but, in reality, it could
be a very serious injury. Immediately provide medical treatment to the
affected area.
These symbols signal the obligation to wear protective gloves, goggles and masks.
Wear clothing that complies with safety regulations in force in the country of the user.
Do not wear bracelets, earrings, rings, chains or other objects that may obstruct the operator's work.
Do not wear clothing with large sleeves, scarves, ties or any other item that can become tangled in the moving parts
of the machine during the operating cycle and inspection and maintenance operations.
This type of machine constitutes a complete and independent
unit for the application of powder coatings.
LARIUS has created this AD CH 200-TRIBO unit which allows
the use of corona effect spray guns (the powder is charged by
electrodes), and triboelectric spray guns (the charge occurs
via friction).
Therefore the same machine can be used as an electrostatic
generator for CH 200 series spray guns, or as a control unit
for the electrostatic charge for LARIUS TRIBO manual and
automatic spray guns.
The conversion from one system to the other occurs via the
simple touch of a switch.
The AD version is the ideal solution when frequent colour
changes are required. As a matter of fact, the powder is sucked
up directly by the original package. If necessary just replace
the box with the powder and clean the suction tube.

• To prevent injuries, repairs of electrical parts must only be
carried out by qualified personnel.
Never tamper with the calibration values of the
instruments.
PRECAUTIONS DURING WORK
• Do not smoke, do not cause open flames.
• Only the spray guns and the vehicles required for trans-
porting the powders must be in the booths: all other the
electrical devices must be outside the booth.
• Ensure that suction capacity in the spray booth is sufficient
and that the powder does not accumulate in any part of
the booth.
• Verify that the frames and all the electrical devices are
properly grounded.
• Ensure the operator is correctly "grounded".
Do not use insulated gloves and plastic shoes. Antistatic
shoes are recommended.
• Do not enter the spray booth when the machine is operat-
ing. Before entering, ensure the locking system of the entire
system is working properly.
•
Facial masks and protective suits are recommended, when
you need to work in environments filled with powder.
• Keep the area surrounding the booth clean, for at least 5
metres.
• Keep the lighting lamps clean. Wash hands and face before
eating or drinking.
HEALTH AND SAFETY
The powders:
• Can cause irritation to the eyes, hands and respiratory
system, after prolonged direct contact.
• Are toxic if inhaled.
• Are not flammable, but they can cause combustion if their
concentration in the air exceeds the allowable limit.

FCORRECT USE OF THE
SYSTEM
The machine described in this manual constitutes a complete
and autonomous unit for the application of powder coatings.
Correct use of the machine allows for the full exploitation of the
performance that is able to provide in conditions of complete
operator safety.
To achieve this, carefully observe the instructions provided below:
• Grounding of all mechanical parts, including the frame of
the machine and, of course, the piece being processed.
Powder leakage:
clean with suction tube. Do not sweep.
Fire:
insulate electrical appliances and use foam.
Contact with eyes:
wash with running water and appropriate medicines.
Inhalation:
go outdoors. Put on clean clothes. If case of res-
piratory difficulty, seek immediate medical attention.
Ingestion:
provide immediate medical care.
The conditions of guarantee do not apply in the
following situations:
- improper washing and cleaning of components
causing malfunction, wear or damage to the
equipment or any of its parts;
- improper use of the equipment;
- use that does not conform with applicable na-
tional legislation;
- incorrect or faulty installation;
- modifications, interventions and maintenance that
have not been authorised by the manufacturer;
- use of non-original spare parts or parts that do
not correspond to the specific model;
- total or partial non-compliance with the instruc-
tions provided.
CONDITIONS OF GUARANTEE
• The powder tube must not be twisted or bent in any way.
• Distance between the electrode and the piece being pro-
cessed.
The safety device of the LARIUS CH 200 electrostatic
system, when below 20mm, causes a reduction in charg-
ing voltage that is so strong that the particles of sprayed
powder are no longer charged.
Therefore it would be wrong to get too close to narrow
points in order to obtain better penetration.
• The operator must wear conductive shoes (leather), no
gloves, as the operator's ground connection is established
through the metal plate on the handle of the spray gun.

• Adjust the powder diffusion range of the spray gun using
the knob (H21) and reading the value expressed in bar on
the pressure gauge (H22), (recommended values 0.5-2 bar);
however, this value must always be less than the supply
air pressure (pressure gauge H23); once adjustment is
complete, release the spray gun trigger.
• Adjust the flow of the additional air that controls the clean-
ing of the diffuser and charging rheophore. Using the knob
(H24) and checking the pressure gauge (H25) set the outlet
air pressure to the recommended values between 0.5-1 bar.
Depending on the amount of powder delivered, ensure the
cleaning cone cleans the powder residue from the affected
areas.
• Using the potentiometer (H26) select the desired voltage
value (0 -100 kv) read the set value on the digital display
(H27).
Protect the spray gun from all violent mechanical
action. Repeated impacts and shocks of consider-
able intensity, while not altering the outer integrity
of the spray gun, may cause internal damage and
cause the spray gun to become unusable.
• Point the spray gun at the object to be painted (recom-
mended distance 15-20 cm) and press the trigger, which
will start to deliver powder, as well as high voltage; the
value of current, expressed in microamperes (max 250 µA)
can be read on the lit indicator (H3).

USE WITH THE TRIBOELECTRIC SPRAY GUN
To use with the triboelectric spray gun, make sure
the selector (H22) is in the "TRIBO" position.
• Point the spray gun at the object to be painted (recom-
mended distance 15-20 cm) and press the trigger, which
will start to deliver powder, as well as high voltage; the
value of current, expressed in microamperes (max 250 µA)
can be read on the lit indicator (H28).
• Adjust the air pressure to the powder supply pump (H29),
by turning the regulator (H30) and reading the value ex-
pressed in bar displayed on the pressure gauge (H23)
(recommended max values 3-4 bar).
• Adjust the powder diffusion range of the spray gun using
the knob (H29) and reading the value expressed in bar on
the pressure gauge (H22), (recommended values 0.5-2 bar);
however, this value must always be less than the supply
air pressure (pressure gauge H23).
• Adjust the "tribo air" pressure using the knob (H24) and
reading the pressure value set on the pressure gauge (H25).
If the pressure is increased, the triboelectric effect is also
increased.
The electrostatic charge value can be read on the luminous
indicator (H28) located on the generator.
At this point, release the spray gun trigger.
Point the spray gun at the object to be pained (recommended
distance 10-20 cm) and press the spray gun trigger, which will
start to deliver powder.
The value of the current expressed in µA (max 10 µA) can be
read on the luminous indicator (H28).
Protect the spray gun from all violent mechanical
action. Repeated impacts and shocks of consider-
able intensity, while not altering the outer integrity
of the spray gun, may cause internal damage and
cause the spray gun to become unusable.

Cleaning the pressure reducer filter
To ensure proper machine operation, follow these rules:
• Ensure proper operation of the pressure reducer lter.
Ensure there is no condensation build-up inside the cup.
If necessary, periodically discharge the condensation by
unscrewing the bleed screw (I6) under the filter cup; the
pressure inside the cup will cause the expulsion of the
condensation.
• Periodically clean the lter cartridge in order to prevent
system performance losses.
Wash the cup with water and dry with a jet of compressed
air.
Adjusting the pressure
Adjust the pressure by turning the knob located on the upper
part of the reducer.
To increase it turn clockwise (+).
To decrease it turn counter clockwise (-).
Do not power the pneumatic system with compressed air that
is excessively dirty or that contains aggressive liquids.

JCOLOUR CHANGING
The design of the CH 200/AD unit allows for quick colour
changing, directly using the original box containing the powder.
To change the colour, proceed as follows:
• Disconnect the electric and pneumatic mains supply that
powers the machine.
• Turn the revolving arm (J1) in order to remove the cardboard
box (J2).
• Lift up the powder suction tube (J3). Loosening the locking
ring nut (J4) it is possible to slide the suction tube along
the revolving arm.
• Remove the box and replace it with that of the new colour
which you intend to use, correctly placing it on the shaking
table(J5).
• Turn the revolving arm (J1) and position it above the powder
container.
• Lower the (J3) powder suction tube inside the container.
• Open the air supply to the machine.
• Press the main switch (J6) of the control panel to power
the generator.
• Turn the switch (J7) of the electric vibrator to the "ON"
position.
