EARTHING

Perfect earthing of all system components (workpieces, conveyor, paint supply system,

coating effi ciency and safety.
A badly earthed work-piece will result in:
•
Sparks between the object being sprayed and the hangar. (danger of explosion)
•
Very poor wrap-around
•
Uneven coating thickness
•
Spray-back onto the spray gun, i.e. contamination
The prerequisites for perfect earthing and coating are:
•
Clean workpiece suspension
•
Earthing of spray booth, conveyor system and hangers to the building earth in accor
dance with the operating instruction or the manufacturer's information
•
Earthing of all conductive parts within the working area
•
The earthing resistance of the work-piece must not exceed 1 MΩ (Mega Ohm).
•
Connect the control unit to the mains system earth.
