CURTIS 1243 Generation 2 MultiMode™ controllers are separately excited motor speed controllers designed for use in a variety of small industrial vehicles and in material handling equipment. These programmable controllers are simple to install, efficient, and cost effective, while offering more features than the original 1243.

The 1243 GEN2 MultiMode™ controller provides smooth precise control of motor speed and torque. A full-bridge field control stage is combined with a half-bridge armature power stage to provide solid state motor reversing and full regenerative braking without additional relays or contactors. The controller's rugged IP53 housing and packaging are built to withstand shock and vibration. State-of-the-art surface mount logic board fabrication makes the 1243GEN2 controller even more reliable than the original 1243. The 1243GEN2 is fully programmable through the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station. In addition to configuration flexibility, the programmer provides diagnostic and test capability.

Features Include:

Interlock braking with load sensor to meet required braking distance without unnecessary harsh braking at light loads
Maintenance monitor responds to preset vehicle operating hours and drive hours as programmed by the OEM
Two hourmeters - total KSI-on hours and traction hours - and the associated maintenance timers are built into the controller
BDI calculations performed within controller
Estimates motor temperature based on field resistance and cuts back maximum speed if the motor is overheated
Diagnostic checks for field open and field shorted faults
Supports PWM electromagnetic brake with maximum continuous current of 2 amps
Supports Type 4 throttle
Active precharge of controller capacitor bank extends life of main contactor
Compatibility with CURTIS 1313-4331 Handheld Programmer or 1314 PC Programming Station for quick and easy testing, diagnostics, and parameter adjustment
MultiMode™ allows four user-selectable vehicle operating modes
Continuous armature current control, reducing arcing and brush wear
Complete diagnostics through the handheld programmer, the built-in Status LED, and the optional 840 Spyglass display
Two fault outputs provide diagnostics to remotely mounted displays
Regenerative braking allows shorter stopping distances, increases battery charge, and reduces motor heating
Automatic braking when throttle is reduced provides a compression braking feel and enhances safety
Brake/Drive Interlock meets ISO stopping distance requirements
Ramp restraint feature provides automatic electronic braking that restricts vehicle movement while in neutral
Meets EEC fault detect requirements
Linear cutback of motor drive current during overtemperature or undervoltage
Linear cutback of regenerative braking current during overvoltage
High pedal disable (HPD) and static return to off (SRO) interlocks prevent vehicle runaway at startup
Internal and external watchdog circuits ensure proper software operation
Fully protected inputs and short-circuit protected output drivers.
