9060 High Voltage Controller - Introduction

INTRODUCTION

GENERAL DESCRIPTION

The Ransburg 9060 High Voltage Control-
ler (80100-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 a cascade that amplifies the
voltage to a high kV level.
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 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 High
Voltage Controller provides maximized opera-
tional safety. The protections include detection
of Boot Faults, 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

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

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 feed-
back signals in the low voltage cable be-
tween the controller and the cascade.
