OPERATING MANUAL
2.5 PROCESSIBLE WORKING MATERIALS
Lacquers which contain ingredients of explosion class IIA and IIB substances (maximum ignition energy 0.24 mJ) can be processed with the GA 5000EAC 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).
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.

VERSION 09/2016 ORDER NUMBER DOC2360922
GA 5000EAC
OPERATING MANUAL
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.
4.2.3 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.
18
VERSION 09/2016 ORDER NUMBER DOC2360922
OPERATING MANUAL
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.
GA 5000EAC
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.

OPERATING MANUAL
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 5000EAC spray gun is activated directly on the EPG5000
control 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 5000EACIC MODE OF OPERATION
Pneumatic diagram:
SA = Shaping air AA = Atomizing air CA = Control air M = Product
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.

SA = Shaping air AA = Atomizing air CA = Control air M = Product
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.
