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
Run bypass mode greatly reduces internal heating created by the greater power dissipation in the SCRs
Internal solid-state overload protection provides accurate current measurement and trip settings
Internal run bypass contactors and overload protection eliminate the need for additional devices
Wide range of overload FLA settings
Variable ramp times and torque control settings provide unlimited starting configurations
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
Pump control option with sophisticated pump algorithms on both starting and stopping that minimize the pressure surges that cause water hammer
Soft acceleration and deceleration reduces wear on belts; gears; chains; clutches; shafts and bearings
