The solid state electronic controls are enclosed in an easily accessible compartment. The controls are mounted to an aluminum heat sink, which provides good thermal performance for the controls.
The wiring harnesses feature Deutsch waterproof connectors.
The traction and pump control along with the dash mounted “multi-function” gauge create a small CANBUS network. The controls record operation and service information that may be accessed by service personnel. The controls also record and display any fault codes that may occur during operation. These fault codes are displayed on both the dash display (via a numeric code) and on the control itself (via an LED “blink” code).
The machine is operated via an electronic foot pedal and the travel direction is selected via a dash mounted joystick switch (IDEC).
The machine also has an on-board DC/DC converter which allows for 12V system items like the head and tail lights and horn. There is a total of 300 watts available which allow the end-user to add additional 12V devices.
Spare power and control fuses are shipped with the machine.
Traction Drive System
The traction system uses a Sevcon SEM control rated at 300 amperes. This means that the traction motor, while still a D.C. motor, has no brushes – this reduces service needs for the traction motor.
The motor is custom built by D&D Motor Systems, a leading DC motor manufacturer.
The motor is directly mounted to the rear axle, which is manufactured by Graziano Trasmissioni. This axle model is similar to those used in thousands of small vehicles (like golf carts).
The rear axle features drum brakes on both wheels and incorporates a parking brake as well.
The traction system has been adjusted to provide full travel speed in the forward direction but for safety, the travel speed in the rear or backwards travel direction has been reduced.
Pump Control System
The pump control system uses a Sevcon Powerpack control rated at 450 amperes. The control has the ability to operate the pump at a variety of speeds. The machine is set-up with a low-speed setting, which is used for off-ice driving to conserve battery power.
