8 Order number 2360922 | Edition 09/2022

Personnel qualifications

Trained person Is instructed in the tasks assigned to him/her, the potential risks associ-

ated with improper behavior as well as the necessary protective devices

and measures.

Electrically

trained person

Is instructed by an electrician about the tasks assigned to him/her, the

potential risks associated with improper behavior as well as the neces-

sary protective devices and measures.

Electrician Can assess the work assigned to him/her and detect possible hazards

based on his/her technical training, knowledge and experience in rele-

vant provisions.

Skilled person in

the context of

DGUV209‑052

A person who, based on his/her technical training, experience and re-

cent vocational experience, has sufficient technical knowledge in the

area of electrostatic coating and is familiar with the relevant and gener-

ally accepted rules of technology so that he/she can inspect and assess

the status of devices and coating systems based on workplace safety.

Additional requirements for skilled persons can also be found in

TRBS1203(2010/amendment 2012): Expert knowledge in the areas of

protection against excessive pressure, electrical hazards and explosion

protection (where applicable).

2 USING IN ACCORDANCE WITH THE INSTRUCTIONS

2.1 DEVICE TYPE

Electrostatic automatic spray gun for coating of grounded work pieces in automatic coating

systems.

2.2 TYPE OF USE

The GA 5000EAC electrostatic automatic spray gun is suitable for spraying liquid products,

particularly coating products. Coating products may be processed which contain

components of substances of explosion group IIA and IIB (maximum ignition energy 0.24

mJ).

WAGNER explicitly prohibits any other use!

The device may only be operated under the following conditions:

4Use the device only to work with the materials recommended by WAGNER.

4Do not deactivate safety fixtures.

4Use only WAGNER original spare parts and accessories.

4The operating personnel must be trained on the basis of this operating manual.

4Follow the instructions in the operating manual.

2.3 FOR USE IN POTENTIALLY EXPLOSIVE AREAS

The GA 5000EAC electrostatic automatic spray gun is suitable for coating electrically

conductive objects with liquid coating products and can be used in potentially explosive

areas.

(See Explosion Protection Identification in chapter Explosion Protection Identification

[811].)

2.4 PROCESSIBLE WORKING MATERIALS

4Coating products whose ingredients contain substances of explosion class IIA and IIB

(maximum ignition energy 0.24 mJ) can be processed with the GA 5000EAC spray gun.

4The basic spray gun 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).

4When processing metallic lacquers, it is advisable to use the spiral hose.

4The application effectiveness 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 specific paint resistance.

Multiplying the result of the measurement with the device-specific cell constant (K), we

obtain the specific 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

R=500kΩ

Operating manual GA 5000EAC Electrostatic Automatic Spray Gun (AirCoat)

2 Using in Accordance with the Instructions

10 Order number 2360922 | Edition 09/2022

Specific resistance (RS) RS=RxK=500kΩx123=61.5MΩcm

Note:

Using sprayed substances with too low an electrical resistance, the application of

electrostatics does not show any effect, 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

4no wrap-around

Info

Contact your local WAGNER dealer and the lacquer manufacturer if you encounter

application problems.

2.5 MISUSE

Misuse can lead to physical injury and/or property damage! Special attention must be paid

that:

4No dry coating products, e.g., powder are processed.

4No food, medicine or cosmetics are processed. It is important to note that the device's

materials are not food-safe.
