Product Description
Setting a New Standard in Motor
Control
Revolutionary in design, Advantage
motor starters employ state-of-the-art
technology in solving motor control
application problems that have existed
for ages. Customer focus group input
and 66,000 man-hours of engineering
ingenuity have been combined to
create a motor starter that dramatically
extends operating life in a physical
space requirement one half the size
of conventional motor starters.
Offering motor overcurrent protection
accurate to 2% at maximum FLC,
Advantage also maintains constant
coil power regardless of varying con-
trol circuit conditions, eliminating coil
burnout, contact chatter and welding
due to low voltage of fluttering control
signals.
Advantage is designed with a full com-
plement of features that make it the
most versatile motor starter in the
industry. Multifunction overload pro-
tection options provide application
flexibility while reducing inventory.
Communication capability extends
benefits, allowing Advantage to be
interactively linked to higher order
control systems for monitoring,
troubleshooting and control.
Technological advances incorporated
in the Advantage design, such as pre-
start diagnostics, increased accuracy
and the ability to communicate with
other systems, are benefits not real-
ized in traditional motor starters.
Benefits
Advantage Breakthroughs
To achieve the level of benefits envi-
sioned for Advantage controls at a
competitive price, it was discovered
early in the development process that
simply improving existing design con-
cepts would fall short of the mark. A
new approach involving a higher level
of technology was required. The result
was the incorporation of three techni-
cal breakthroughs — new current
sensing monitoring, an energy-
balanced contact closure system that
increased life by decreasing electrical
and mechanical wear and an intelli-
gent coil controller optimizing the con-
tact closing process based on varying
control circuit conditions. Coordinat-
ing these breakthroughs to provide
enhanced motor control performance
is concentrated in the SURE chip.
Patented SURE Chip Increases Life
Advantage uses the right combination
of brains and brawn in effecting a
motor start. The power circuit of the
contactor employs heavy-duty silver
alloy contacts scientifically designed
for long life. The addition of a uniquely
developed application-specific micro-
processor chip, called SURE, regulates
power supplied to the operating coil.
The regulated closing profile is tai-
lored to existing control circuit condi-
tions by the SURE chip. This results in
an energy balanced system which
reduces armature/magnet crash and
contact bounce, extending mechani-
cal and electrical life.
Improved Protection and Motor
Utilization
The motor circuit monitoring and over-
load protection functions of Advan-
tage starters are provided by three
current sensors closely monitored by
the SURE chip. This sensor/micropro-
cessor combination yields a protection
scheme closely paralleling that of the
motor heating damage boundary
expressed in terms of current and
time. Accurate to 2% of full scale,
Advantage allows full utilization of
motor capability without motor dam-
age or nuisance tripping.
No Heaters, Small Size
Advantage starters eliminate the
need for costly heater elements and
their associated installation expense.
Standard overload protection func-
tions include phase loss and unbal-
ance protection, selectable trip class,
automatic/manual reset and ground
current protection.
Built-In Communications
Capabilities Provide Two-Way
Control
Advantage also offers low cost com-
munication capability. ON/OFF com-
mands, status and motor data can be
linked to automated control systems
without the addition of costly sensors,
I/O modules and transducers, in
a language compatible with many
computer-based software systems in
use today.
Protected by 22 patents and proven in
many years of operating experience in
harsh industrial applications, Advan-
tage motor starters and contactors
offer the user unprecedented value at
a price competitive with traditional
devices.
