Aerbell 33 Rotary Atomizer - Maintenance
Ransburg
32 LN-9521-00.4
Bad Spray Pattern
Low or No High
Voltage
Bell cup damaged
Low voltage
Bad fluid regulator
Paint lodged in shaping air ring.
High current draw
Solvent valve is actuated
Loss of high voltage connection at
the power supply
Loss of high voltage connection at
the resistor module
Loss of high voltage connection at
the turbine assembly
Power supply failure
Improper limiting current and volt-
age settings
Atomizer grounding out (usually
indicated by high current draw)
Damaged high voltage cable be-
tween atomizer and power supply
Improper color change (i.e., paint or
solvent in dump line)
Replace bell cup.
See "low or no voltage" below.
Repair or replace fluid regulator.
Disassemble and clean.
Paint resistivity to be .1 MΩ to ∞.
Remove solvent valve air pilot signal (high
voltage must be interlocked with the solvent
valve air pilot signal to prevent solvent flow
while high voltage is energized).
Ensure proper high voltage connection at
the power supply. Refer to "Low Voltage
Test" in the "Weekly Maintenance" section
of this manual.
Verify high voltage connection into the re-
sistor module. Refer to "Low Voltage Test"
in the "Weekly Maintenance" section of
this manual.
Verify high voltage tube connection into
the turbine housing and resistor module.
Refer to "Low Voltage Test" in the "Weekly
Maintenance" section of this manual.
Refer to the power supply manual for de-
tailed troubleshooting guide.
To readjust settings, refer to the power
supply manual.
a. Clean atomizer externally with non-polar
solvent.
b. Check the atomizer for internal fluid leaks.
c. Check for internal arcing (usually indicated
by internal sparking sounds).
Repair or replace high voltage cable.
Optimize color change.
