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 1313-4401 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.
