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
(80102-31X)
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 control.
It uses a variable voltage output to drive a cascade that
amplifies the voltage to a high kV level. It also uses current
feedback information to maintain the desired set point. The
processor circuitry provides the maximum in applicator
transfer efficiency, while maintaining the maximum safety.
The 9060 Controller selection and adjustment of set point
values is performed from the controller front panel. The
triggering of the HV is initiated by the airflow switch built
into the controller which senses airflow triggered by the
No. 2 Process Handgun.
SAFETY FEATURES
The Ransburg 9060 High Voltage Controller provides maxi-
mized operational safety. The protections include detection
of Ground Faults, Cable Faults, Feedback Signal Faults,
Overvoltage, and Overcurrent. 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 opera-
tional 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 gun current output. The gun current is
derived from feedback signals between the controller and
the cascade.
