INTRODUCTION
GENERAL DESCRIPTION
The Ransburg Spray Process
The Ransburg Spray Process is an air atom-
ized method for applying coatings to objects
electrostatically. This system applies a high
voltage DC charge to the applicator nozzle
electrode, creating an electrostatic field
between the atomizer and the target object.
The target is electrically grounded through its
support that may be either stationary or
moving.
A regulated pressure fluid system delivers
coating material to the atomizer. At the
atomizer, air is applied that atomizes the
coating material forming a spray mist that,
under the influence of the electrostatic field,
becomes electrically charged. The charged
particles are attracted to, and deposited on,
the target object. The forces between the
charged particles and the grounded target are
sufficient to turn most normal overspray
around and deposit it on the side and back
surfaces of the target. Therefore, a high
percentage of the spray is deposited on the
target.
9060 Power Supply
The 9060 Cascade Control Unit converts
standard AC line voltage to a high frequency,
low voltage signal ranging from 0 to 10 Vrms.
This signal is supplied to an external cascade
through a low voltage cable. The external
cascade converts the low voltage signal into a
high voltage. This high voltage is transmitted
through the cable to the applicator. At the
applicator an electrode in the applicator
creates a DC high voltage field the spray goes
through and picks up the electrostatic charge.
When the material is directed to a grounded
target, more material is attracted to the target
yielding higher painting efficiency.
The voltage/current characteristic is designed
to optimize the charging process under
varying load conditions, and to limit the
operating current to a safe maximum value.
In addition to supplying low voltage output to
the applicator, the 9060 Cascade control unit
also provides controls for AC power ON/
OFF, infinite high voltage adjustment, a high
voltage meter, a current meter, an AC power
ON indicator, a high voltage ON indicator, a
cable fault indicator, and a current overload
indicator and reset switch. Additionally,
output terminals are provided for remote
overload reset, analog current output, and
high voltage control. Interlock connections
for a conveyor and exhaust fan are also
provided. A combination triple setpoint/
analog input control board is also supplied
with 9060 Cascade control units powering
automatic spray applicators.
9060 Power Supply Kit
80143 and 80146
The 9060 Power Supply Kit 80143-XXX and
80146-XXX are designed to be used with
either the Esta-Quick Applicator (AEMD 600)
or the Evolver SE product (A12455-XXXX).
Both use an oil filled cascade.
The only combination of units that carry
any approval is the AEMD600 used with the
80143-XXX units as described in this manual.
Any other combination of applicator and 9060
unit does not have any agency approval as-
sociated with it. When using equipment that
is not approved, the user needs to be aware
of the code requirements needed to operate
safely. If there is any question regarding safe
installation requirements when using this
product, refer to European Norms (EN 50
176) or NFPA-33.
