Understanding DIP Switch Settings
DIP switches on the SMC-3 configure vital settings like current limits and start times. Refer to the manual for specific switch positions‚ ensuring correct motor operation. Incorrect settings may cause malfunctions or overload trips. The trip rating is 120% of the dial setting‚ so precise configuration is crucial. Always align settings with the motor’s FLA to avoid issues. Use the manual’s guidance for accurate DIP switch configurations and reliable performance. Proper setup ensures smooth motor operation and prevents potential damage. Follow the manual’s instructions carefully for optimal results.
Overload Protection Configuration
Overload protection on the SMC-3 is configured by adjusting the overload dial based on the motor’s Full Load Amps (FLA). The trip rating is set to 120% of the dial setting. To configure‚ align the dial with the motor’s FLA‚ ensuring the trip current matches 1.2 times the dial setting. For example‚ a motor with 41 FLA requires a dial setting of approximately 34A. This ensures the overload protection triggers correctly. The system also supports automatic or manual reset modes‚ providing flexibility in motor control and protection. Proper configuration is critical for preventing motor damage and ensuring reliable operation. Always refer to the manual for precise settings and guidelines.
Adjusting the Overload Dial
Adjusting the overload dial on the SMC-3 ensures precise motor protection. To set‚ turn the dial until the desired current aligns with the pointer. The trip rating is 120% of this setting. For a 41A motor‚ set the dial to 34A‚ as 1.2 times 34A equals 40.8A‚ close to the required 41A. This configuration prevents motor overload damage. Always match the dial setting to the motor’s specifications for optimal performance and safety. Proper adjustment ensures reliable operation and protects the motor from excessive current conditions. Refer to the manual for detailed instructions and guidelines.
