Bulletin Product Overview/Modes of Operation/Features Bulletin Smart Motor Controllers SMC - Smart Motor Controller The SMC- is a compact, simple to use, solid-state motor controller designed to operate -phase motors. It features a built-in overload relay and a built-in SCR bypass contactor on all three phases, allowing a smaller footprint than other soft starters on the market. This product is designed for many applications, including compressors, chillers, pumps, conveyors, and crushers. Modes of operation for the controller are as follows: Soft Start Soft Stop Current Limit Start Kick Start The controllers offer two voltage ranges: V AC and V AC. All voltage ranges will operate at either or Hz. A Range Built-In Electronic Motor Overload Protection Built-In SCR/Run Bypass Delta Compatibility Table of Contents Explanation - Product Selection... - Typical Wiring Diags. - Specifications... - Approx. Dimensions. - Enclosed Options... - Accessories... - This catalog is based on the minimum information needed to select an SMC soft starter for applications with low starting torque requirements. For product selection involving loads with high starting torque requirements (large fan, rock crusher, chipper, etc.), use of the free tools available from the Rockwell Automation Website is recommended: http://www.ab.com/industrialcontrols/products/solid-state_motor_control/software/ Standards Compliance UL CSA C. No. EN/IEC - EN/IEC -- Modes of Operation Soft Start Selectable Kickstart Current Limit Start Soft Stop Note: For detailed information about the different modes of operation, see page - Description of Features Electronic Motor Overload Protection The SMC- controller incorporates, as standard, electronic motor overload protection. This motor overload protection is accomplished electronically with the use of current transformers on each of the three phases. The controller s overload protection is programmable, providing the user with flexibility. The overload trip class selection consists of either OFF,,, or. The trip current is easily selected by adjusting the rotary potentiometer to the motor full-load current rating. Trip reset is selectable to either automatic or manual mode. Note: Trip rating is % of dial setting. Over-temperature The SMC- monitors the SCR temperature by means of internal thermistors. When the power poles maximum rated temperature is reached, the microcomputer switches off the SMC, a TEMP fault is indicated via LED, and the / fault contact closes. Phase Reversal Protection When enabled via a DIP switch, -phase input power will be verified before starting. If input power phasing is detected to be incorrect, the start will be aborted and a fault indicated. Phase Loss/Open Load The unit will not attempt a start if there is a single-phase condition on the line. This protects from motor burnout during single-phase starting. Certifications culus Listed (Open Type) (File No. E, Guides NMFT, NMFT) CSA Certified (File No. LR ) CE Marked (Open Type) per EMC and Low Voltage Directive CCC Certified Phase Imbalance The unit monitors for imbalance between phase currents. To prevent motor damage, the unit will trip if the difference between the minimum phase current and the maximum phase current exceeds % for s, and a fault will be indicated. Shorted SCR Prior to every start and during starting, the unit will check all SCRs for shorts and unit load connections to the motor. If there is a shorted SCR in the SMC- and/or open load, the start will be aborted and a shorted SCR or open load fault will be indicated. This prevents damage from phase imbalance. Push to Test The unit with control wiring can be tested for fault conditions by using the Push to Test function. Hold down the Reset button for s to activate the fault Aux (, ) and shut down the SMC-. To clear, either push the Reset button or cycle control power to the device.
