FUNCTION TEST AFTER THE REPAIR
After all repairs, the device must be checked for safe condition before recommissioning.
The necessary scope of inspection and testing depends on the repair carried out and must
be documented by the repair staff .
11.1
CHECKING THE HIGH VOLTAGE
Necessary test equipment:
EPG 5000 control unit and HV 200 high-voltage tester.
High-voltage measurement on spraying gun.
Connect gun cable to control unit. Mount spray gun to grounded gun mounting.
Switch on the control unit.
The high voltage should be 60 to 65 kV in dry ambient air. The value can be checked with
the display on the control unit (EPG 5000).
Note:
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 50
to 55 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 70 to 80 kV.
Notes:
- When measuring the high voltage 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.
