S E PA R AT E L Y E X C I T E D E L E C T R O N I C MOTOR SPEED CONTROLLER MODEL 1266 SepEx® FEATURES Smooth and Secure Control • Power MOSFET technology provides smooth, silent, efficient, and cost-effective operation. • Adjustable parameters enable custom optimization of speed, torque, and braking control. • Half bridge armature and full bridge field provides regenerative braking down to near zero speed. • Rugged package rated at IP5X. • Overspeed braking (regenerative) limits speed while driving downhill. • WalkAway™ braking feature limits any stopped or key-off rolling to very low speed. (Optional) • System uses Hall effect speed sensor on motor or drive train to control vehicle speed. • Tow switch enables free rolling for towing of vehicle. • Anti-rollback function provides improved control when throttle is released on hills. • Anti-stall function helps prevent motor commutator damage. • Controller drives warning buzzer -- steady in reverse; intermittent during WalkAway™ braking. • MultiMode™ input provides for two speed and power modes of operation. DESCRIPTION Curtis PMC Model 1266 SepEx® controllers are programmable and microprocessor based, with an advanced MOSFET power • Timed shutdown of main contactor after pedal is released and vehicle has stopped. section for smooth and seamless control of separately excited • LED status indicator. motors. • Fully compatible with 1311, 1314 and 1307 Programmers for parametric adjustment, tuning, test, and diagnostics. APPLICATION Curtis PMC 1266 SepEx® controllers are designed for use in two passenger golf/utility vehicles. • Extensive fault detection and diagnostic reporting using a Curtis Programmer including (partial list): – Main contactor weld check and driver check – Throttle and wiring faults – Open or shorted motor field winding – Open motor armature winding – Over-temperature – Missing or failed speed sensor – Armature drive failure. www.curtisinstruments.com
