Features

• 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, increase uptime by providing data for process management and preventive diagnostics
• 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
• Internal solid state overload protection provides accurate current measurement and trip settings, sophisticated algorithms solve a series of differential equations that model true motor heating and cooling, resulting in superior motor overload protection while minimizing nuisance trips
• Advanced selectable protective features safeguard the motor and system against a variety of system faults
• Internal run bypass contactors and overload protection eliminate the need for additional devices, reducing enclosure sizes minimizing installation and wiring time and reducing overall assembly size and cost
• Wide range of overload FLA settings (50 to 100% of rated frame current) and a selectable trip class (5 to 30) offers users the flexibility to fine tune the starter to match specific application requirements
• 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
• Soft stop control for applications where an abrupt stop of the load is not acceptable
• Six SCRs control all three motor phases, providing smooth acceleration and deceleration performance
• Soft acceleration and deceleration reduces wear on belts, gears, chains, clutches, shafts and bearings
• Reduce the peak inrush current stress on the power system
• Minimize peak starting torque to diminish mechanical system wear and damage
• 120 VAC control voltage enhances ease of connections
• The S611 lends itself to serviceability, the printed circuit boards (PCBs) and contactors can be replaced in the field
• The S611 has built-in communication capabilities through two communications ports to connect the soft starter to a variety of networks, including Modbus® (resident), DeviceNet, PROFIBUS and Ethernet
• 15 hp at 208 VAC, 15 hp at 240 VAC, 40 hp at 480 VAC, 50 hp at 600 VAC
