Description:

Curtis PMC Model 1243 SepEx programmable controllers provide smooth and seamless regenerative control of separately excited motors. An advanced MOSFET power section, combined with a sophisticated microprocessor provides very high efficiency, silent operation and reduced motor and battery losses.

Application:

Curtis PMC Model 1243 SepEx controllers are designed for small material handling and other light industrial vehicles using separately excited motors. These include low lifts, stackers, personnel carriers and other industrial vehicles.

• Unparalleled Driving and Braking Feel
• Regenerative braking allows shorter stopping distances, increases usable battery energy, and reduces motor heating. The half bridge armature drive topology allows regenerative braking down to zero vehicle speed.
• "Ramp Restraint" feature provides automatic electronic braking that restricts vehicle movement while in neutral.
• Vehicle speed is controlled by the throttle, at all times including down hills.
• "Load Compensation" provides improved loaded versus unloaded speed regulation by compensating for losses in the armature.

Fully Programmable

• Fully compatible with the Curtis Models 1311 and 1314
• programmers for programming, test, and diagnostic information.
• MultiMode™ feature allows four user selectable vehicle operating profiles. Each profile has separate drive current limits, brake current limits, acceleration rates, brake rates and maximum speeds.

Easy to Install and Maintain

• No direction contactors are required. The full bridge field driver topology allows motor reversing without the use of direction contactors.
• Simple wiring and installation by the elimination of the direction contactors and the use of positive battery connections for all inputs and driver outputs.
• Can be configured to match most separately excited motors and vehicle applications.
• An auxiliary driver output supports an electro-magnetic brake, pump contactor, or hour meter. A programmable delay allows for customization of this driver output.
• An integral fault LED flashes helpful error code information. Two fault outputs provide diagnostic information for dash mounted displays. Diagnostic faults are logged and the history is viewable through a Curtis Model 1311 and 1314 programmer.

Powerful Safety Features

• Meets or exceeds EEC fault detection requirements. Circuitry and software to detect faults in the throttle circuit and MOSFET drive circuits help prevent unsafe operation.
• Emergency reverse feature causes quick vehicle reversal upon activation. The emergency reverse input wire can also be checked for continuity.
• Programmable HPD and SRO interlock options ensure proper startup sequence.
• Complies with the CE standards for electromagnetic compatibility in emissions and susceptibility.
• Active power on self test and continuous diagnostics during operation. Internal and external watchdog circuits ensure proper software operation.
• All inputs and outputs are fully protected.
