Safety-related information concerning harmless discharge

When the high voltage is turned on, a glow or corona discharge, that is only visible in a dark environment, occurs at the electrode tip. When the electrode approaches the grounded workpiece, this physical phenomenon can be observed.

This glow discharge does not provide any ignition power and does not have any influence on the handling of the installation. When the electrode approaches the workpiece, the control device automatically reduces the high voltage to a safe level or turns off the high voltage depending on the setting.

If the finger comes in contact with the plastic parts of the spraygun, harmless discharges (so-called brush discharges) can occur. The charging of the plastic parts is caused by the high voltage electrostatic field of the gun. However, these discharges do not provide any ignition power.

1.2 Warranty

What is covered by this warranty:

Faulty and useless parts are replaced according to our general delivery conditions.

Within the applicable warrant period, Wagner will repair or replace, at our option, defective parts without charge if such parts are returned with transportation charges prepaid to the nearest authorized service center. If Wagner is unable to repair this product so as to conform to this Limited Warranty after a reasonable number of attempts, Wagner will provide, at our option, either a replacement for this product or a full refund of the purchase price of this product.

These remedies are the sole and exclusive remedies available for breach of express and implied warranties.

What is not covered by this warranty:

No ability to transfer:

This warranty is extended to the original purchaser only and is not transferable.

Your rights under state law:

Some states do not allow limitations on how long an implied warranty lasts or the exclusion of incidental or consequential damages, so the above limitation and exclusion may not apply to you. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.

2. Description

2.1 Application

The Airmatic spraygun PEA-C2 is used for industrial powder coating.

The spraygun can be used with the following control unit:

EPG 2007:
This control unit is integrated part of the ECOTECH Automatic Control
System.
or may be operated with the following module combination in customized control
cabinets:
Module PM 300:
Adjusting and displaying feeding and dosage air
Adjusting and displaying atomizing air
Anti-interference printed board assembly:
The protective printed board assembly is attached to the module HVM 2072
Module HVM 2072:

For regulating the high voltage

Caution

The spraygun may only be used for the above described
application.

2.2 What powder materials can be used?

Basically, all coating powders can be used with the Airmatic spraygun PEA-C2. e.g.: epoxy resin, polyester, blended powder EP / PES, PUR.

Caution

Powders containing metal pigments may only be processed in compliance with the powder manufacturer’s instructions.

2.4 Operation of the spraygun

When the high voltage switch at the control unit EPG 2007 (resp. high voltage module HVM 2072) is turned on, the high voltage is activated in the PEA-C2. At the same time, the powder and compressed air supplies to the gun are turned on.

A high DC voltage (up to 100 kV), applied across the grounded workpiece and the electrode fitted to the gun body generates an electric field and applies a negative charge to the powder particles. These repel each other as they move from gun to workpiece and so distribute evenly through the fine spray cloud and then uniformly deposit on the grounded surface. Particles shooting past the component remain trapped in the electric field and deposit on the backside of the work object.

Caution

To provide a safeguard against unintentional use of the spraygun, the control unit must be turned off.

Malfunction	Cause	Remedy
No electrostatic charge (e.g. no wrap-around or no powder adhesion)	- Fault at high voltage generator - Electrical cable between spraygun and control unit defective - Cascade in spraygun is defective	- Inform service center - Inform service center - Inform service center
Poor wrap-around Back-spray	- Bad grounding - No grounding	- See paragraph 3.2. - See paragraph 3.2.
Powder output irregular or insufficient	- Impurities - Powder sintering - Impurities in delivery system - Compressed air main supply insufficient - Feeding air / dosage air proportion not correct - Wear	- Blow through powder feeding parts - Clean powder feeding parts - See operating instructions of connected devices - Check air main supply - Readjust at the control unit - Change worn out parts
Spray cloud not correct	- Nozzle system worn out	- Replace nozzle system
