The SMC-2 Controller is configured with DIP switches and a rotary digital switch. Soft Start, Current Limit, Full Voltage in one unit. The controller has pre-start protection from phase loss and shorted SCRs. An LED is provided to indicate the status of the unit. The LED is ON when 3-phase power is applied. A flashing LED indicates one of 3 conditions: shorted SCR or phase loss during start, or a stalled motor during run. Protection Stall protection available during starting and run condition for additional motor protection. Energy Level Built-in energy saver available for low load conditions. 2- and 3-wire control for wider variety of applications. Interface option requires no additional space and Wiring can be factory or field installed. Auxiliary Selectable auxiliary contact available for either up-to-speed or instantaneous operation. Contact Module allows for soft stopping to minimize load shifting. Also adjusted from standard DIP switches.
