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
complement of features that make it
the most versatile motor starter in the
industry. Multifunction overload
protection 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
realized in traditional motor starters.
Features, Functions, 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
concepts would fall short of the mark.
A new approach involving a higher
level of technology was required. The
result was the incorporation of three
technical breakthroughs — new
current sensing monitoring, an
energy-balanced contact closure
system that increased life by
decreasing electrical and mechanical
wear and an intelligent coil controller
optimizing the contact closing process
based on varying control circuit condi-
tions. Coordinating these break-
throughs 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 the SURE chip,
regulates power supplied to the oper-
ating coil. The regulated closing profile
is tailored to existing control circuit
conditions by the SURE chip. This
results in an energy balanced system
which reduces armature/magnet crash
and contact bounce, extending
mechanical 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%, Advantage
allows full utilization of motor capability
without motor damage or nuisance
tripping.
No Heaters, Small Size
Advantage starters eliminate the need
for costly heater elements and their
associated installation expense. Stan-
dard overload protection functions
include phase loss and unbalance
protection, selectable trip class,
automatic/manual reset and ground
current protection.
Built-In Communications
Capabilities Provide Two-Way
Control
Advantage also offers low cost
communication capability. ON-OFF
commands, 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.
