THE EMX3 IS THE LATEST DEVELOPMENT
IN SOFT STARTERS PROVIDING A
COMPLETE MOTOR STARTING AND
MANAGEMENT SYSTEM.
WITH AN IMPRESSIVE RANGE OF
FEATURES IN A SINGLE USER FRIENDLY
PACKAGE, NEVER BEFORE HAS MOTOR
CONTROL BEEN SO SIMPLE.
MORE CONTROL
Not only does the EMX3 soft starter
feature Constant Current and Current
Ramp, but the EMX3 is the world’s first
soft starter to control acceleration. We
call it Adaptive Acceleration control.
According to your application require-
ments you can now select between early,
constant or late acceleration/decelera-
tion. This level of choice is only available
from AuCom.
More control means smarter starts and
smoother stops that reduce downtime
and eliminate water hammer problems.
EASY TO USE
The EMX3 is easy to use during installation,
commissioning, operation and even trouble
shooting.
Quick setup gets your machinery running
in next to no time, informative screens
advise your operator on the performance
of your motor and real language trip
messages pinpoint exactly where any
issues lie.
Options for control wiring from the
top, bottom or left side provide greater
flexibility, plus unique wiring looms and
cable retainers make for a faster, tidier
install. You’ll soon experience how easy
the EMX3 is to use.
FEATURE SET
The EMX3 is a smart, dependable and
easy to use soft starter. New design
features make the EMX3 the perfect
solution for quick set-up or more
customised control, including:
• Large LCD screen with multi-language
feedback
• Remote mountable keypad station
• Intuitive programming
• Advanced start and stop control
functions
• A complete range of motor protection
features
• Extensive performance monitoring and
event logging

XLR-8: ADAPTIVE
ACCELERATION CONTROL
AuCom’s new EMX3 soft starter
introduces a new generation in soft start
technology: XLR-8 Adaptive Acceleration
Control. XLR-8 gives you an unprecedented
level of control over your motor’s
acceleration and deceleration profiles.
Using XLR-8, the soft starter learns your
motor’s performance during start and
stop, then adjusts control to optimise
performance. Simply select the profile
that best matches your load type and
the soft starter automatically ensures the
smoothest possible acceleration for your
load.
Contact your local distributor to see an
EMX3 demonstration today.
XLR-8: ADAPTIVE ACCELERATION CONTROL
THE EMX3 SIMPLIFIES THE INSTALLATION AND
OPERATION OF MOTOR STARTING SYSTEMS TO
REDUCE INSTALLATION COST AND TIME.
ADAPTIVE ACCELERATION PROFILE OPTIONS
Adaptive acceleration offers three start and stop profiles according to your needs.
The EMX3 comes in a range of sizes to suit the demands of your application. See rating and sizes for details.

METERING AND
MONITORING
The EMX3 delivers an extensive range
of information to replace an additional
powermeter (Amps, kW, kVA, pf).
PROGRAM MULTIPLE UNITS
When programming multiple units,
simply plug the keypad into different
starters for immediate download of
your data. No fuss, no trouble – a
smoother star t in every sense.
EASY TO UNDERSTAND DISPLAY
REAL LANGUAGE IN REAL TIME
AuCom wants to make your job easy, so
the EMX3 gives real-language feedback
messages, so you don’t have to look up
codes to know what’s happening. With
real-time metering displays and a 99-
place event log recording time-stamped
details of operation and performance, it
has never been easier to track how your
motor is behaving.
GRAPHICAL DISPLAY
In many cases we’ve done away with
language altogether, using real-time graphs
of motor operating performance and
current to quickly and clearly illustrate
exactly how your motor is performing.
REMOTE DISPLAY MOUNTING
The keypad is easily mounted on the
exterior of your enclosure, using an
optional keypad mounting kit. When
mounting multiple soft starters in a
single enclosure, this allows centralised
control from a single location, with all the
relevant information. Mount a number
of displays next to each other for quick
diagnosis of problems. (IP65 when
mounted).

SMARTER STARTING
The EMX3 puts you in control of motor
starting. Depending on your application
requirements you can select the best soft
start control method.
For applications requiring precise control
of motor start current the EMX3 offers
a choice of Constant Current or Current
Ramp start modes. For superior control
over acceleration or deceleration choose
XLR-8 Adaptive Acceleration Control.
SMOOTHER STOPPING
XLR-8 also provides precise control over
soft stopping and is ideal for applications
requiring a smoother soft stop. XLR-8 is
ideal for low inertia loads such as pumps
and conveyors, and can substantially reduce
or eliminate the effects of water hammer.
BRAKING
For high inertia loads, the EMX3
incorporates AuCom’s latest braking
algorithm, letting you take precise
control over the motor’s stopping time.
Shorter stopping times help improve
your production efficiency by reducing
downtime between operating cycles.
ADVANCED OPERATION
To meet the unique requirements of your
application, the EMX3 offers a range of
advanced features. The EMX3 meets the
needs of specific applications including:
•Pumping(e.g.highheadapplications)
• Compressors(optimisingloadcontrol)
• Bandsaws(easybladealignment)
• Irrigators(built-intimer).
SIMULATIONS
Need to test the installation before
connecting a motor? The EMX3
simulation functions let you test the soft
starter’s operation, external control
circuits and associated equipment
without connecting the soft starter to
line voltage or a motor. The EMX3 has
three simulation modes:
• Run simulation: simulates a motor
starting, running and stopping to
ensure correct installation.
• Protection simulation: simulates
activation of each protection
mechanism to confirm correct
protection response.
• Signalling simulation: simulates
output signalling.
EASY TO INSTALL, EASY TO OPERATE
EASIER INSTALLATION
If space is at a premium in your motor
control centre, the EMX3’s compact size
will save you space and trouble. Internal
bypass contactors, built-in monitoring and
indicators, and extensive on-board input
and output functionality reduce the need
for space and cost of external equipment,
as well as simplifying installation.
REMOVABLE CONNECTORS &
UNIQUE WIRING LOOM
Installation is easy with plug-in control
terminal blocks. Simply unplug each
block, complete the wiring and re-insert
the block.
Using the EMX3’s unique and flexible
cable ways, cables can be efficiently
organised for wiring from either the top,
left or from below.
FASTER COMMISSIONING
The EMX3 has been designed for ease of
use, and the user-friendly menu is no
exception. After a tidy installation, a
quick setup guide helps you configure
the starter for common applications by
suggesting a typical setting, which you
can then fine tune to suit your needs, all
accessible from the easy to use keypad.
