Curtis 1207B Manual
✓ Circuitry and software detects faults in the throttle circuit, MOSFET
drive circuit, MOSFET transistors, contactor drivers, and contactors—
ensuring that the controller meets EEC fault detect requirements
✓ Input sequencing options include neutral start and static return to off
(SRO)
✓ Microprocessor-controlled contactor sequencing provides true arcless
contactor switching
✓ Smooth, controlled plug braking—with either variable (throttle-
dependent) or fixed plug current limit
✓ Neutral braking option provides automatic plug braking in neutral
✓ MultiMode™ input selects between two different operating modes,
thus allowing optimization of vehicle characteristics for different driving
conditions
✓ Emergency reverse (belly-button switch) with a single input
✓ Ramp-start feature provides full power for starting on ramps
✓ Simple contactor and switch wiring, with coil drivers monitored for
faults—thus ensuring fail-safe operation
✓ Flexible throttle circuitry accommodates a variety of throttle types
✓ Programmable “ramp shape” (static throttle map) provides flexibility in
selecting throttle response feel
✓ Connections made by solid copper power busses with a polarized Molex
connector for control signals
✓ Solid, well-protected construction—with an aluminum mounting plate
and injection-molded cover.
Familiarity with your Curtis controller will help you install and operate it prop-
erly. We encourage you to read this manual carefully. If you have questions,
please contact the Curtis office nearest you.
