Curtis 1214-/15-/19-8 Manual 2
and linear rollback in overtemperature—thus preventing sudden power
loss regardless of thermal conditions
✓ Intelligent handheld 13XX programmer provides a full set of parameter
and function settings
✓ Diagnostic and test information for the controller—and other system
components—readily available through both an on-board LED and the
optional handheld programmer
✓ Meets or exceeds EEC fault detect requirements, with circuitry and
software to detect faults in the throttle circuit, MOSFET drive circuits,
MOSFET output, contactor drivers, and contactors
✓ Programmable input sequencing options include several combinations
of neutral start and static return to off (SRO)
✓ Arcless contactor switching with microprocessor-controlled contactor
sequencing
✓ 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) provides full function
with a single input
✓ Anti-rollback (ramp start) provides full power for starting on ramps
✓ Simple contactor and switch wiring, with coil drivers monitored
for shorts and open circuits—thus ensuring fail-safe operation
✓ Flexible throttle circuitry accommodates a variety of throttle types:
5kΩ–0, 0–5kΩ, 0–5V, 0–10V, inductive, Hall, etc.
✓ Programmable “ramp shape” (static throttle map) provides flexibility
in selecting throttle response feel
✓ Sealed package, providing environmental protection
✓ Power connections made by tin-plated solid copper busses,
with a polarized Molex connector for control signals
Familiarity with your Curtis controller will help you install and operate it
