8.6 FUNCTION TEST AFTER ASSEMBLY OF THE GUN
8.6.1 TEST OF THE HIGHVOLTAGE
Necessary test equipment:
VM 500 or VM 5000 control unit and HV200 high-voltage tester.
High-voltage measurement 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 50 to 60 kV in dry ambient air. The value can be checked with the display on the
control unit (VM 5000).
Notice
The gun must be clean and dry and must not have any paint or cleaning agent residues.
In the case of ambient air with a high air humidity, the measured value can reduce to 40 to 50 kV.
High-voltage measurement with high-voltage tester
Place the ball of the high-voltage tester on the gun electrode and turn on the high-voltage. The measured
value should be 60 to 70 kV.
Notice
- When measuring the high-voltage the gun and the measuring device should be held at arms length as far
from the body as possible.
- There should be no chargeable objects within 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 ground with the grounding rod. No sparks should be formed.
Note: in the vicinity of the electrode harmless corona discharges can occur.
