Electronic motor starters
CSXi Series to 110 kW
CSXi overview
The CSXi is a compact closed loop controlled current soft starter
intended for use with 3 phase motors ranging from 7.5 to
110 kW at 400 V AC. Designed with the ‘first time’ soft start
user in mind, the CSXi incorporates a number of unique
features aimed specifically at simplifying the installation
and commissioning processes while also significantly reducing
installed cost. In order to achieve this the CSXi is provided with
Equi-Vec™ balanced vector control technology, a comprehensive
array of motor and system protection features including in-built
bypass contactor and in-built thermal overload with adjustable
trip class, all as standard.

CSXi-007-V4-C1
In operation, the CSXi provides smooth acceleration and
deceleration of the motor and connected load, thereby
minimising the electrical and mechanical stresses that would
otherwise be encountered through the use of electromechanical
motor starting methods.
Equi-Vec™ technology
6
Equi-Vec™ balanced vector control is state-of-the-art technology
developed to enhance the performance of 2 phase soft start
controllers. By balancing the current vectors during motor
starting, the CSXi is able to provide 3 phase like performance
while maintaining the commercial and mechanical advantages
normally associated with compact soft starter technology.
Standard starting modes
Constant current/current limit soft start
The constant current start mode is ideally suited to highly
inertial applications. Due to the nature of this starting mode
highly inertial loads are brought up to speed in the shortest time
possible, thereby minimising thermal stresses on the motor.
In-built motor & system protection
The CSXi provides a comprehensive array of motor and system
protection features to further satisfy the most demanding of
industrial motor control applications. This eliminates the need to
purchase/install additional devices, thus acting to reduce
installed cost.
In-built protection features are summarised as follows;

In-built bypass contactor
To further reduce installation complexity and cost the CSXi is
provided with in-built bypass contactor as standard. This
eliminates the need for external bypass contactors and/or the
need to force ventilate enclosures.

Timed current ramp soft start
The timed current ramp start mode allows the user to set
minimum starting current, maximum starting current and a start
ramp time. This method of starting is proven in applications that
present a variable starting torque requirement, for example a
conveyor that at times may start fully loaded and at other times
will be lightly loaded, or to extend the start time of loads that
easily break away.

Electronic motor starters
CSXi Series to 110 kW
Standard stopping modes
Excess start time protection
Timed voltage ramp soft stop
The CSXi will trip if the starting time exceeds the motor’s safe
starting time characteristics, ensuring the motor is not subjected
to high currents for an excessive period of time. This feature
will also ensure the load is not jammed or too large at start up.
During soft stop, the CSXi gradually decreases output voltage
over a user selected ramp time enabling driven machines to be
stopped gently. This is of particular advantage in applications
where machinery and or product can be adversely affected by
sudden stopping. Examples include pumps and conveyors.
Notes: The soft stop feature can be disabled by selecting a ‘0’ stop
time. The soft start and soft stop ramp times are independently
adjustable.
Supply frequency error
The supply frequency during start and run may vary under some
conditions including generator power situations. The CSXi
monitors supply frequency to ensure that it is not operating
outside its design parameters thus preventing damage to itself
and the motor.
Phase sequence protection
Phase sequence protection is of particular advantage in
applications that are rotation direction sensitive such as pumps,
compressors etc. The CSXi will monitor the incoming phase
rotation before application of power to the motor to prevent
incorrect rotation of the motor. This feature is user configurable
to fwd or any phase sequence application.
Communications failure
Protection features further explained
Electronic motor overload protection with user
adjustable motor thermal model.
The CSXi soft starter provides built-in motor overload protection
with adjustable thermal model as standard.
The thermal model allows the user to select the tripping curve
which most closely resembles the thermal withstand curve of the
connected motor. This eliminates nuisance motor overload
tripping, while maximising machine up-time and plant
productivity.
User adjustable Motor FLC and thermal model via rotary switches
located on the front panel.
Motor thermistor protection
In order to further enhance motor protection, the CSXi provides
an input for direct connection of your motor thermistors.
Phase imbalance protection
The CSXi offers phase imbalance protection as standard. During
both start and run, the CSXi monitors motor current through its
internal current transformers. In order to prevent motor damage,
burn out or over heating, the CSXi will trip if an imbalance
exceeds specified limits or a phase loss occurs.
Power circuit protection
Prior to the application of power to the motor but following a
start command, the CSXi monitors its line and load connection
and the integrity of its SCRs. Should any abnormality be
detected, the CSXi will trip thus ensuring the motor is not
compromised.
Automated plants utilise the communications features of the
CSXi. Connection integrity is vital to maintain control and
protection of the motor. The CSXi monitors the communications
link to maintain supervisory control and displays a fault when a
break occurs.
CSXi Set-up
Although the CSXi offers broad functionality, set-up is a simple
process. A series of clearly labelled rotary switches is provided to
ensure accurate and repeatable settings are easily made. Simply
rotate these to the desired position (no need for a user manual)
and you’re ready to go.
Fault & status information
Fault and status information is provided by on-board ‘flash
coded’ LEDs. In addition, the RCM-02 remote operator is
available for those who may require/benefit from remote control
and monitoring.
