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 EPG 5000 ontrol
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 off the mains at the EPG 5000
2. Switch off the air supply at the EPG 5000
3. Relieve the pressure of the spray gun and system

GA 5000EAIC 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 fi 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 fl 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 infl uence each other during adjustment.
