9060 Cascade Low Voltage Controller - Introduction

INTRODUCTION
GENERAL DESCRIPTION
The Ransburg 9060 Cascade Low Voltage
Controller
(80120-XXX) is used to provide
high voltage for electrostatic application
equipment. It uses a combination of proven
high voltage generation technology and
microprocessor-based control. It uses a
variable voltage output to drive an external
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 main-
taining the maximum safety.
The 9060 Controller can operate in either
LOCAL mode or REMOTE mode conditions.
In the LOCAL mode, the selection and adjust-
ment of set point values is performed from the
controller front panel. The triggering of the HV
in LOCAL mode is initiated by the optional
airflow switch built into the controller (which
senses airflow triggered by a standard hand-
gun) or via a single discrete remote I/O trigger
signal. In REMOTE mode, the selection and
adjustment of the set point can be performed
using either discrete or analog remote I/O
signals. Two tripleset signals are provided
that can be used to select one of the same
three presets that are set and used in LOCAL
mode. Two analog remote I/O set point
signals are provided, one for current and one
for voltage, and can be used to control the set
point (See the Operation portion of this
Manual for more information). The REMOTE
mode triggering of HV is performed using a
single discrete remote I/O trigger signal.
SAFETY FEATURES
When used with the appropriate applicators
and cascades, the Ransburg 9060 Cascade
Low Voltage Controller provides maximized
operational safety. The protections include
detection of Ground Faults, Cable Faults,
DISPLAYS
The front panel displays the high voltage set
point as well as a reading of gun current out-
put. The gun current is derived from feed-
back signals in the low voltage cable be-
tween the controller and the cascade.

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
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 low voltage
controller is based on load.
