VERSION 09/2016 ORDER NUMBER DOC2360924
2.5 PROCESSIBLE WORKING MATERIALS
Coating products which contain ingredients of explosion class IIA and IIB substances
(maximum ignition energy 0.24 mJ) can be processed with the GA 5000EA spray gun.
The spray gun basic version is suitable for processing sprayed substances with an
electrical resistance of > 150 kΩ (according to the WAGNER scale).
Equipped with a special product hose for low-resistance sprayed substances (available
as an accessory), you can also successfully process sprayed substances with an
electrical resistance > 50 kΩ (according to the WAGNER scale).
When processing metallic lacquers, it is advisable to use the spiral hose.
The application e ectiveness is always dependant on the composition of the product
being used, e.g., pigments or resin.
Conversion of Paint Resistance
There are paint resistance measuring devices available on the market that do not directly
measure the speci c paint resistance.
Multiplying the result of the measurement with the device-speci c cell constant (K), we
obtain the speci c resistance value of the product.
Example:
With WAGNER's paint resistance measuring device the cell constant is K =123.
Measured value according to the WAGNER scale
Speci c resistance (RS)
Note:
Using sprayed substances with too low an electrical resistance, the application of
electrostatics does not show any e ect, i.e. there is no "paint wrap around" on the object
to be sprayed.
The suitability of the spray product with regard to the charging ability can be read from the
actual values for high voltage (kV) and for the spray current (μA) shown in the illuminated
displays on the EPG 5000 control unit.
High kV value, low μA value = ok
Low kV value, high μA value = excessive conductivity of the paint
No wrap-around
Please contact your local WAGNER dealer and the lacquer manufacturer if you encounter
application problems.

GA 5000EA
OPERATING MANUAL
VERSION 09/2016 ORDER NUMBER DOC2360924
4.2.3 PRODUCT HOSES
Ensure that the hose material is chemically resistant to the sprayed products and the
used ushing agents.
Ensure that the product hose is suitable for the pressure generated.
Ensure that the following information can be seen on the high-pressure hose:
- Manufacturer
- Permissible operating pressure
- Date of manufacture
Make sure that the hoses are laid only in suitable places. Hoses should not be laid in the
following places under any circumstances:
- in high-traffic areas,
- on sharp edges,
- on moving parts or
- on hot surfaces.
Ensure that the hoses are never run over by vehicles (e.g., fork lifts), or that the hoses are
never put under pressure from the outside in any other way.
Ensure that the hoses are never kinked. Observe maximum bending radii.
Make sure that the hoses are never used to pull or move the equipment.
Suction hoses may not be subjected to pressure.
Several liquids have a high expansion coe cient. In some cases their volume can rise with
consequent damage to pipes, ttings, etc. and cause uid leakage.
When the pump sucks liquid from a closed tank, ensure that air or a suitable gas can
enter the tank. Thus a negative pressure is avoided. The vacuum could implode the tank
(squeeze) and can cause it to break. The tank would leak and the liquid would ow out.
The pressure created by the pump is a multiplication of the inlet air pressure.
4.2.2 GROUNDING THE DEVICE
Friction, owing liquids and air or electrostatic coating processes create charges. Flames or
sparks can form during discharge. Grounding prevents electrostatic charging.
Ensure that the device is grounded. See Chapter "Grounding".
Ground the work pieces to be coated.
Ensure that all persons inside the working area are grounded, e.g., that they are wearing
static dissipative shoes.
The spray substance supply (spray substance tank, pump, etc.) must be grounded.

4.2.4 CLEANING AND FLUSHING
Relieve the pressure from the device.
De-energize the device electrically.
Preference should be given to non- ammable cleaning and ushing agents.
Observe the speci cations of the lacquer manufacturer.
Ensure that the ash point of the cleaning agent is at least 15 K above the ambient
temperature or that cleaning is undertaken at a cleaning station with technical
ventilation.
Take measures for workplace safety (see Chapter 4.1.3).
When commissioning or emptying the device, please note that an explosive mixture
may temporarily exist inside the lines and components of equipment:
- depending on the coating product used,
- depending on the ushing agent (solvent) used,
explosive mixture inside the lines and items of equipment.
Only electrically conductive tanks may be used for cleaning and ushing agents.
The tanks must be grounded.
An explosive gas/air mixture forms in closed tanks.
Never spray into a closed tank when using solvents for ushing.
External cleaning
When cleaning the exterior of the device or its parts, also observe the following:
Disconnect the pneumatic supply line.
Use only moistened cloths and brushes. Never use abrasive agents or hard objects and
never spray cleaning agents with a gun. Cleaning the device must not damage it in any
way.
Ensure that no electrical component is cleaned with nor even immersed into solvent.
Which cleaning agent is used to clean the spray gun depends on which parts of the
spray gun have to be cleaned and which product has to be removed. When cleaning the
spray gun, only use non-polar cleaning agents to prevent conductive residues on the
surface of the spray gun. Should it however, be necessary to use a polar cleaning agent,
all residues of this cleaning agent have to be removed by using a non-conductive and
non-polar cleaning agent, once the cleaning is nished.

The spray gun is a component of a stationary coating system. When setting up stationary
coating systems, comply strictly with EN 50176. One of the requirements is that activation
of the high voltage is only possible by using a key. But it must be possible to switch o the
high voltage without a key.

4.6 SAFETYRELEVANT INFORMATION ABOUT DISCHARGES
The plastic parts of the spray gun are charged electrostatically by the high-voltage eld
of the spray gun. Contact with plastic parts harmless discharges (brush discharges) may
occur. They are completely non-hazardous for human health.
When keeping a distance of 4 to 10 mm; 0.15 to 0.4 inches between spray gun and object
to be sprayed, the corona discharge at the end of the electrode is visible in the dark.

5.2 MODE OF OPERATION
Note:
Operation of the spray gun in conjunction with the EPG 5000 control unit is described in
this operating manual.
➞ The high voltage for the GA 5000EA spray gun is activated directly on the EPG5000ontrol
unit or by a signal from the superordinate controller.
➞ The high voltage for the spray gun can be adapted via the voltage regulator on the
EPG 5000 control unit and can be adjusted to the paint or to the spraying object.
➞ Secure gun:
1. Switch o the mains at the EPG 5000
2. Switch o the air supply at the EPG 5000
3. Relieve the pressure of the spray gun and system
5.2.1 GA 5000EAIC MODE OF OPERATION
Open:
The piston in the drive is charged with control air and moves toward the rear. This ensures
that the air valve which releases the shaping and atomizing air is opened rst. The product
valve is then opened with a mechanical delay. In this position, the pressurized coating
product is applied to the work piece.
Close:
The piston is relieved, and the product valve closes due to the pressure spring which
presses against the product valve tappet. The air valve is then closed, again with a spring
force and mechanical delay.
Additional functions:
The shaping air throttle is used to regulate the shaping air volume, while the atomizing air is
adjusted via an external pressure regulator. The two air streams do not ow separately until
downstream of the air valve, so that the pressure of the shaping air corresponds roughly to
that of the atomizing air and so that they in uence each other during adjustment.

5.2.2 GA 5000EAEC MODE OF OPERATION
Open:
First, the external air valve, which enables the shaping and atomizing air, is opened.
The diaphragm in the drive is then charged with control air and moves toward the rear,
opening the product valve. In this position, the pressurized coating product is applied to
the work piece.
Close:
If the control air is deactivated, the product valve closes due to the pressure spring.
The air valve is then closed externally.
Additional functions:
The shaping air pressure and the atomizing air pressure are set externally via separate
pressure regulators. Both air ows are supplied separately, which allows them to be set
separately.

Spray product
Atomizing air
Advantages
- Thin layers
- Uniform coating thickness
- Perfect nish
In this process, the spray product is fed to the nozzle with a pressure of approx. 0.05–0.2 MPa;
0.5–2 bar; 7–29 psi. The atomizing air at approx. 0.25 - 0.4 MPa; 2.5 - 4 bar; 36 - 58 psi produces
a soft round jet, which largely eliminates the problem of overlapping boundaries. There are
various nozzles and air caps available as accessories for the respective spray product and
the discharge quantities.
