Resistance test
This measurement must be carried out by a qualified electrician.
If the atomizer been disassembled, the electrical resistance between
chuck and paint pipe and between chuck and turbine must be
measured after reassembly. The bell disk must not be mounted yet.
The electrically conductive parts in the atomizer are electrically
interconnected to one another. Due to this connection, the electrodes
and the leads carry high voltage when operating the atomizer at high
voltage.

Risk of damage to property and production disruption
Malfunction of high voltage due to excessive resistance.
After working on the inside of the atomizer, check the resistance.
A resistance test shows whether the electrical connection of the parts
with one another is OK:
- The resistance between chuck and color tube must be
≤
10Ω. Test
voltage 4-24V.
- The resistance between chuck and shaft/turbine must be
≤
0.1MΩ.
Test voltage 50V.
If the resistance is higher, the atomizer must be disassembled again.
Check all contact surfaces. Then assemble the atomizer again.

Final work after fault removal
After cleaning and maintenance work, always check the distance
between shaping air ring and bell disk. The distance may have
changed.
A T T E N T I O N
Risk of damage to property and production disruption
In case of wrong assembly, shaping air ring and bell disk can rub
against each other. Shaping air ring and bell disk can be damaged.
Check distance between shaping air ring and bell disk. The bell disk
should not rub against the shaping air ring.
