1 — OVERVIEW
Like all Curtis motor controllers, the 1243GEN2 offers superior operator control
of the vehicles motor drive speed. 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 1307/1311 handheld programmers 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
