7.5.3 SETTINGS OF HIGHVOLTAGE CHARACTERISTIC
Regardless of the high voltage and spray current limitation set, the characteristic curve of
the voltage/current curve can be set on the EPG S2 control unit.
Three levels are possible:
1. Standard level -> maximum EPG S2 performance
2. Medium level ->reduced EPG S2 performance
3. Soft level -> greatly reduced EPG S2 performance
Properties of the characteristic curve Field of application/remarks
Standard level – for poorly rechargeable types of powder
– Open-circuit voltage 100 kV – for high powder application
– Maximum current 120 μA
(Current limiting)
– This setting corresponds to the usual
WAGNER high-voltage modules and
control units.
Medium level – for small surfaces
– Open-circuit voltage 100 kV – for types of powder that recharge well
– Maximum current 120 μA
(Current limiting)
– To reduce the e ects of overcoating such
as craters and orange peel.
– Increasing the open-circuit voltage
allows for a greater distance between
the spray gun and the work piece while
maintaining su cient powder charging.
Soft level – for types of powder that recharge well
– Open-circuit voltage 100 kV – for small powder application
– Maximum current 80 μA – for post-coatings
The characteristic slope can be set at three levels.
The graphic shows the characteristic curves for the three di erent slopes.
