Solution
Cause Problem
• Rapid wear of Venturi diffuser
• The powder puffs out of the spray
gun
• Insufficient powder flow
• The powder is not sufficiently
electrostatically charged and/or
does not “cover”
• The powder "cover" but the µA
scale does not increase
• No mains voltage;
• Worn or partially clogged Venturi;
• The additional air pressure is exces-
sive (rack central regulator) or the
ratio between this and the powder
delivery air pressure is incorrect (left
rack regulator);
• The tank's fluid bed air pressure is
excessive or insufficient;
• The unidirectional valves of the pow-
der pump are partially clogged;
• Powder passage tube too short or
with excessive inner diameter;
• The air pressure for adjusting the
powder delivery is insufficient;
• The powder is too wet and is sucked
up by the powder pump with difficulty;
• Worn or partially clogged Venturi;
• The additional air pressure (central
regulator rack) is excessive;
• The additional nozzle cleaning air
pressure is excessive;
• The piece to be painted is not properly
electrically grounded;
• The powder is not suited for use with
a corona and/or triboelectric system;
• Only for triboelectric spray gun: •
The "tribo" air pressure (central
regulator rack) is excessive;
• For CH 200 spray gun: nozzle dam-
aged and/or dirty;
• For triboelectric spray gun: charge
tube dirty and/or damaged;
• Display board not working;
• For triboelectric spray gun: tribo-
corona switch set to"corona";
• Use a hard metal Venturi diffuser
(code 5296/A);
• Clean and/or replace the Venturi;
• Decrease the additional air pres-
sure and/or increase the powder
delivery air pressure.
Important: The additional air pres-
sure must always be lower than the
powder delivery air pressure;
• Adjust the fluid bed air pressure
(recommended pressure value:
0.5-1bar);
• Clean and/or replace the unidirec-
tional valves;
• Use the powder passage tube
supplied or a tube with an inner
diameter that is no greater than
12mm and with a length no less
than 5 metres;
• Increase the air pressure to adjust
powder delivery;
• Check the compressed air supply
line. Install an air dryer if necessary;
• Clean and/or replace the Venturi;
• Decrease the additional air pres-
sure;
• Decrease the additional air pres-
sure;
• With a tester or similar instrument
check the electrical grounding of
the piece holder hooks. If neces-
sary, clean the piece holder hooks;
• Consult the powder supplier;
• Increase the "tribo" air pressure to
increase the triboelectric effect;
• Clean and/or replace the nozzle;
• Clean and/or replace the charge
tube;
• Replace the display board;
• Move the switch to "tribo";
