This controller is designed for use in pallet truck applications. The 1212S controller is fully programmable by means of an original programming device for Curtis. Use of the programmer offers diagnostic and test capability as well as configuration flexibility. Like all motor controllers for Curtis, the 1212S offers superior operator control of the vehicle’s motor drive speed. Key Features: Smooth and Secure Control. Advanced speed regulation maintains precise speed over varied terrain, obstacles, curbs, and ramps. Linear cutback of current ensures smooth control, with no sudden loss of power during under-voltage or over-temperature. Proprietary algorithms help prevent gearbox wear while providing smooth starts and reversals. The vehicle is brought to a complete stop before the electromagnetic brake is applied, ensuring safe and secure stops under all conditions. Charger inhibit input prevents driving while charger is attached. Key Off Decel function ensures a smooth “brake to stop” when the key is turned off while driving or when a fault occurs that requires the vehicle to stop. Anti-Rollback/Roll-forward function provides smooth and safe vehicle control on hills and ramps. Internal main relay provides secure power-off. Boost current gives a brief boost of current greatly improving transient loads such as starting on a hill, crossing thresholds, etc. Easy Installation and Setup. Industry standard footprint, mounting centers, and wiring allows drop-in replacement of other controllers. 1212S controller is easily programmed with an original programming device for Curtis, or can be supplied pre-programmed. Accepts standard single-ended voltage/resistance throttles. Throttle sense can be inverted for all throttle types. Simplified troubleshooting and diagnostics. Standard Mini-Fit-Jr. Terminals for Molex provide proven connections for the control wiring. Bolt-on terminals provide robust connections for the high current wiring Valuable Additional Features. Automatic compensation for changes in motor condition to ensure optimum drive performance at all times. Multi-mode provides for two distinct and programmable control modes (indoor/outdoor). Emergency reverse with belly button switch input. Lift Lockout input from 906 battery discharge indicator meter for Curtis. Output Lift Lockout signal, which can drive a pump contactor. Pump SRO can be enabled to prevent pump startup when KSI first turned on. Sleep function prevents the controller draining the battery when the vehicle is inactive. Battery Discharge Indicator output. Adjustable brake hold voltage reduces heating of the brake coil. Reverse polarity protection Robust Safety and Reliability. High RF immunity prevents speed variation and shutdowns in noisy RF environments. Controller power circuits and microprocessor software are continuously monitored for proper operation. On power-up, system automatically checks the throttle, brake, and associated wiring, and disables drive if a fault is found. Whenever the 1212S senses a loss of KSI or any fault that requires a stop, it smoothly decelerates the vehicle to a stop Meets or Complies with Relevant US and International regulations. Electronics sealed to IP54. Designed to meet EN 12895:2000, EN 13849-1(PL=B, Cat 2), and UL583. Package Included. 1 x Motor Controller Note. Battery is not included. Packaging Details. G. Usually it costs about 30USD-50USD. Thanks for your understanding. If you receive the item that not satisfied or defective, please do not open case and kindly notify us within 30 days.
