3 CONTROLLER FEATURES
3.1 The SC2000 range of controllers offer the following features:
* 24-48V, 72-80V and 72-96V operation. Current limits of 500, 650A and 1000A.
* Enclosed unit to IP34 with Field-replaceable logic.
* Traction + Pump motor controllers in one enclosure.
* Also standalone Traction and standalone Pump controllers available.
* Microprocessor control.
* High frequency (silent operation).
* Start-up safety sequence and Static return to Off (SRO).
* Internal watchdog monitoring microprocessor operation.
* Arcless contactor switching and built-in contactor coil suppression.
* Use of 24V contactors at all voltages possible.
* Switch inputs configurable to be normally open or normally closed.
* Active low inputs switched to B-, or active high inputs switched to B+ (Factory option).
* Low input impedance for protection against water (active low inputs).
* Thermally compensated current limit.
* Selectable accelerator characteristics.
* Adjustable creep speed.
* Bypass with over current drop out.
* Field weakening.
* Seat switch timer.
* Power steer contactor and timer.
* Regenerative or Plug braking only, both high frequency and silent.
* Braking proportional to accelerator or optionally non proportional.
* Electric braking in neutral.
* Electric braking with brake pedal. (Switch or Potentiometer required)
* Under-voltage and over-voltage protection.
* Accelerator wire-off detect.
* Flexible accelerator interface with minimum/maximum voltages programmable.
* Inching and timed burst-inching facilities.
* Economy pot input initiating either increased acceleration delays or reduced current limit.
* Short-circuit and open-circuit contactor detect.
* 2 Traction cut-back speeds with independent acceleration delays.
* 7 pump speeds with Priority, Additive and Compensation features available.
* Inhibit input to disable pump operation, from external source such as BDI.
* Independent Power Steer speed and compensation settings, with ramp up/down delays.
* Hardware and Software fail-safe protection + autofailsafe check every power-up.
* Contactor drive short circuit detection.
* Fault detection with LED display.
* Serial communications bus (CANbus).
* Adjustments made using plug-in calibrator with optional levels of access.
* Diagnostics & Service information with calibrator.
* Hours Counter displaying Key Switch, Pump and Traction pulsing hours on calibrator.
* BDI. Battery discharge indicator with adjustable warning and cut out levels.
* Dual motor non proportional and proportional variants with steer switch or steer pot inputs.
* Dual Motor steer angles can be adjusted to match truck geometry when using a steer pot.
* Dual Motor independently adjustable ramp-up / ramp-down settings for smooth cornering.
* Controller extrusion has ‘T’ slots for direct mounting of Albright contactors.
* Speed limit facility optionally available with speed sensor.
* Resettable Service and Fault logs.
* Non-English Languages selectable on calibrator.
* Standard Dashboard Display available displaying BDI, Hours, Steer angle and diagnostics.
* Full Feature Dashboard Display also available. As above but custom LCD with graphics.
* Setup menu on calibrator to enable and disable common options.
