GENERAL DESCRIPTION
The Ransburg No. 2 Handgun Process
The No. 2 Process
TM
is an electrical atomization method
for applying coatings to objects electrostatically. The No. 2
Process Handgun system applies a high voltage, negative,
DC charge to the applicator bell, creating an electrostatic
field between the bell and the target object. The target is
electrically grounded through its support which may be
stationary or moving; or through an electrical connection
to a known true earth ground.
A regulated pressure fluid system delivers coating mate-
rial to the bell when the gun is triggered. There, the fluid
travels across the face of the rotating bell and becomes
charged. The fluid is electrically atomized at the edge of
the bell forming a fine mist which, under the influence of the
electrostatic field, is attracted to and deposited on the target
object. The forces between the charged particles and the
grounded target are sufficient to turn almost all overspray
around and deposit it on the side and back surfaces of the
target. Thus, a high percentage of the spray is deposited
on the target and overspray is controlled.
The 9060 High Voltage Controller
The Ransburg 9060 High Voltage Controller (80102-21X)
is used to provide high voltage for the No. 2 Process
Handgun. It uses a combination of proven high voltage
generation technology and microprocessor-based con-
trol. It uses current feedback information to maintain the
required kV output for the No. 2 Process Handgun. The
processor circuitry provides the maximum in applicator
transfer efficiency, while maintaining the maximum safety.
The 9060 Controller for the No. 2 Process Handgun has
a fixed setpoint value which can NOT be adjusted. The
triggering of the HV is initiated by the on-off switch on the
No. 2 Process Handgun.
SAFETY FEATURES
The Ransburg 9060 High Voltage Controller provides maxi-
mized operational safety. The protections include detection
of Boot Faults, Ground Faults, Cable Faults, Feedback
Signal Fault, Current Limit Fault and Overvoltage Fault.
The microprocessor circuits provide a controlled output load
curve, which limits the high voltage output to safe levels
while monitoring control and feedback signals for unsafe
conditions. Maximum operational safety is obtained when
the correct applicator settings are used and when safe
distances between the applicator and target are observed
and followed. The maximum efficiency of the high voltage
controller is based on load.
DISPLAYS
The front panel displays the high voltage set point as well
as a reading of the gun current output. The gun current is
derived from feedback signals between the controller and
the cascade.
