NCX STOCK or OEM Products for SHUNT Wound Electric Motors

The NCX product line are Non-Programmable Controllers used with motors.  These units are designed specifically for factory equipped golf cars.

Customers demanded higher quality after-market replacement with a warranty  instead of “REBUILT USED Controllers”.  Alltrax stepped up and designed a NEW product with a NEW warranty, the NCX Non-Programmable controllers.  A cost effective solution to replace your aging or damaged stock controller without buying a “rebuilt controller”.

  • Programmable via RS232 comm port using PC or Laptop
  • Integrated anodized heat-sink with multi bolt pattern for flexibility
  • Fully encapsulated epoxy fill – environmentally rugged design
  • Available in 300 through 650 amp Performance versions
  • Advanced MOSFET power transistor design for excellent efficiency and power transfer
  • ½ Speed reverse option and “Plug Brake” options available

Features include:

  • Factory Programmed (These are not field programmable by the customer)
  • Integrated anodized heat-sink with multi bolt pattern for flexibility
  • Fully encapsulated epoxy fill – environmentally rugged design
  • Advanced MOSFET power transistor design for excellent efficiency and power transfer
  • 1/2 Speed reverse
  • Reverse Beeper Output

SPECIFICATIONS

These units are designed for OEM (Original Equipment Manufacturers) stock replacement controllers for stock cars with stock motors only. With a peak current rating, they are not designed for lifted or high performance vehicles. The design follows the motor manufacturers current and power recommendations.

For a high-performance controller application – Please order our DCX motor controllers. The NCX controllers are not field programmable and must be ordered for the exact car you are installing them in.  (DCS or PDS only)

MODEL BREAKDOWN

Model number breakdown, for example the { NCX300-DCS } is broken down as:

  • NCX – Family name
  • 300 – First three digits = amperage, = 300 Amp model
  • Xxx-DCS – “Option Identifiers” = Throttle Setting for Factory programming of DCS car, (xxx-PDS is the Power Drive System programming)

Product Wiring Connections

NCX Stock Wiring Connections

Uses standard 9 pin wire harness. Plug the stock wire harness onto the pins on the front of the controller.

Uses our PDXA harness (included): Connect the 10 pin and two 4 pin connectors to the matching connectors on the stock wire harness.

Note: The 4 pin motor speed connector from the motor is not used in this application.

LED Status Indicator

The LED located on the front of the unit provides status of the units operation and used for troubleshooting.

The LED Blink Codes occur at power up, the number of green blinks indicates the throttle configuration:

  • 1 Green LED flash = 0-5 kohm resistive
  • 2 Green LED flashes = 5K-0 ohm resistive
  • 3 Green LED flashes = 0-5 Volt
  • 4 Green LED flashes = EZ-GO inductive (ITS)
  • 5 Green LED flashes = Yamaha 0-1K ohm resistive
  • 6 Green LED flashes = Taylor-Dunn 6-10.5 Volt
  • 7 Green LED flashes = ClubCar 5k-0 ohms, 3-wire throttle

Normal display status:

  • Solid Green: Controller ready to run
  • Solid Red: Controller in programming mode (using Controller Pro)
  • Solid Yellow: Controller throttle is wide open, controller is supplying max output, and is not in current limit.

Troubleshooting:

Error code display: # of RED blinks indicates any error conditions that might exist:

  • 1 Red = Throttle Position Sensor Over Range. Check for open wires.
  • 2 Red = Under Temperature. Controller below -25C
  • 3 Red = HPD. Throttle hasn’t gone to zero during this power on cycle.
  • 4 Red = Over Temperature. Controller over 95C
  • 5 Red = Not used
  • 6 Red = Battery Under Voltage detected. Battery V < under voltage slider
  • 7 Red = Battery Over Voltage detected. Battery V > over voltage slider
