BELL CUP TESTING
(NON-ROTATING)
Check bell cup voltage using Ransburg test meter
kit, part number 76652-01 or 76652-04. Verify that
the output voltages have not varied much from the
set up standard. A drastic change in voltage can
be an early indicator of a component or system
problem. The data shown below was collected
under ideal lab conditions using a clean atomizer
and an unloaded fluid delivery system.
• The following data is for use with the RMA-101
or Aerobell 33R atomizers. The output voltage
measured at the bell will normally range between
91% and 97% of the kV set point displayed at
the control unit.
• The following data is for use with the Aerobell 33
atomizer. The output voltage measured at the
bell will normally range between 85% and 91%
of the kV set point displayed at the control unit.
Bell Cup Handling
Always verify that high voltage is turned OFF and
the atomizer bell has stopped spinning before
performing any type of handling maintenance.
Do not attempt to hold a rag or a
gloved hand against the bell edge
to stop or slow down a rotating bell.
Do not attempt to clean the bell
edge while the bell is rotating.
Do not use sharp or abrasive
materials to clean the bell, which
will scratch the semi-conductive
coating on the surface of the bell.
Do not attempt to place a high
voltage probe on the bell edge
unless rotation is full stopped.
Do not use ammonia solutions or
reclaim solvent containing d-Lim-
onene to clean the bell cups.
Do not use the bell cup to spray
coatings containing N-methyl
pyrrolidone.
Do not reuse an atomizer bell
that shows signs of damage
such as nicks, heavy scratches,
dents, or excessive wear (defined
under "Bell Cup Cleaning", bullet
number 3).
Do not use ultrasonic devices to
clean the atomizer bell cup.
OPERATOR / MAINTENANCE
***WARNINGS***
Do not use N-methyl pyrrolidone
to clean the bell cup.
Do not attempt to use sharp or
abrasive materials to clean the
bell, which will scratch or damage
the plastic bell.
