FUNCTION TEST AFTER ASSEMBLY OF THE GUN
6.6.1
CHECKING THE HIGH-VOLTAGE
Necessary test equipment:
VM 500 or VM 5000 control unit and HV200 high-voltage tester.
High-voltage measurements on spraying gun.
Connect gun cable to control unit. Take the spray gun in your hand and hold into open space. Switch on control
unit and actuate trigger guard.
The high-voltage should be 60 to 65 kV with dry ambient air. The value can be checked with the display on the
control unit (VM 5000).
Note
The gun must be clean and dry and must not have any colour or cleaning agent residues.
BIn the case of ambient air with a high air humidity, the measured value reduces to 50 to 55 kV.
High-voltage measurement with high-voltage tester
Place the ball of the high-voltage tester on the gun electrode and switch on the high-voltage. The measured
value should be 70 to 80 kV.
Note
- When measuring the high-voltage the gun and the measuring device should be held at arms length as far
away from the body as possible.
- There should be no chargeable objects with in a radius of 1 m; 3.28 ft of the place where the measurements
are taken.
- The placing of the measuring ball of the high-voltage measuring device reduces the spraying of the
high-voltage electrode. As a result the high-voltage value increases compared to the spraying in the free
space.
Disruptive discharge test
Check the gun against earth with the earthing rod. No sparks should be formed.
Note: In the vicinity of the electrode can occur harmless corona discharges.
