1 — OVERVIEW
Like all Curtis motor controllers, the 1243
GEN
2 offers superior operator control
of the vehicle’s 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
