Motor Control

The IT. Intelligent Technologies line of Reduced Voltage Soft Starters are compact, multi-functional, easy to install, and easy to program. Designed to control acceleration and deceleration of 3-phase motors, the line is available for current ranges from 12 amp through 1,000 amp applications and is suitable for mounting in motor control centers or in enclosed control (NEMA 1, 4, 4 X and 12) applications. The IT. Intelligent Technologies Soft Starters offer integral run bypass, motor overload protection and advanced diagnostics.

The IT. S811 Communicating Soft Starter has been recognized by EC&M for 2005 as a category winner in the motors, drives & motor controls category.



IT. S801/S811 Soft Starters
The S801/S811 line of Intelligent Technologies Soft Starters is designed to be the smallest, most compact soft starter in the market today. With this small size, it can easily fit in place of existing soft starter designs, wye-delta starters or across-the-line NEMA and IEC starters. This feature allows easy retrofits of existing Motor Control Centers or Enclosures and saves the expense of replacing existing structures or adding a new one to house a soft starter. The product is designed to work with 3-phase motors in a Delta (3-lead) configuration. The S801/S811 works with all motors from fractional horsepower up to motors requiring 1000 amps of steady state current. The built-in over-load (in ranges from 12 - 1000 amps) and run bypass contactor make installation and setup quick and easy. The overload also offers some advanced protective functions to give additional motor protection.

With the pump control option, it is the number one soft starter available for pumping applications. The unique soft stopping control provides a smooth transition for stopping a motor and eliminating the "water-hammer" effect that can damage pipes, valves, and pumps.

Tru-Start
The Tru-Start "soft-start" starter is a general purpose, full featured starter which offers an "off the shelf" solution for most motor applications at a very economic price. The Tru-Start incorporates oversized SCR's and a class 20 solid-state over-load which will smoothly accelerate most motor loads and will require a minimum of maintenance or adjustment. Simple selection and installation ensures that the application is up and running with a minimum of effort. Additional options may be installed to provide smooth stop, up to speed detection, jam detection, energy saver and shorted SCR detection. The Tru-Start is designed to accomplish smooth reversing with the addition of four SCR's and a reversing logic board. DC injection stopping is also available as a standard option.

S611 Soft Starters
The Eaton S611 is an innovative, economical soft starter combining advanced functionality, unsurpassed configuration flexibility, and an extremely comprehensive user interface. It is available in both open and enclosed control configurations to meet the needs of the commercial construction and OEM segment.

Features

• Available up to 450hp @ 600Vac
• CSA certified, UL listed and IEC 60947-4-2 compliant.
• The User Interface Module (UI) provides an intuitive, easy-to-use human interface with powerful configuration capabilities to maximize system performance.
• Door or device mounted UI enables users to safely configure, commission, monitor and troubleshoot the system at the electrical panel without opening the enclosure door, eliminating the possibility of an arc flash incident.
• System operating parameters can be monitored enterprise-wide through a communications network. Two built-in communications ports enable the soft starter to be connected to a variety of networks including Modbus (resident), DeviceNet, PROFIBUS, and Ethernet.
• Run bypass mode greatly reduces internal heating created by the greater power dissipation in the SCRs. Bypass contactors directly connect the motor to the line and improves system efficiency by reducing internal power losses.
• Advanced monitoring and protection capabilities including overload, underload, overcurrent, phase loss, phase reversal, jam, stall, auto-manual reset, shorted SCR and over-temperature. It also monitors power consumption, voltage, current, and temperature among other parameters.
• Internal solid-state overload protection with a wide range of overload FLA settings (50-100% of rated frame current) and a selectable trip class (5-30)
• Variable ramp times and torque control settings provide unlimited starting configurations, allowing for maximum application flexibility.
• Kick-start feature enables soft starting of high friction loads.
• Pump control option with sophisticated pump algorithms on both starting and stopping that minimize the pressure surges that cause water hammer. The pump control option will maximize the life of the pump and piping systems while minimizing the downtime caused by system failure.
