The DFX Controller Concept

We reinvented engine control for off-highway equipment by creating a simple modular plug and play system that reduces cost, simplifies installation, and increases control capabilities. Our unique system consists of our AE-120 engine controller I/O module, a standardized plug and play engine harness, a simplified single M12A cable extension harness, and our family of display products. This system is designed for applications from simple manual engine start/stop to sophisticated automatic engine start/stop with integrated I/O or utilizing our CANbus J1939modular general purpose I/O module or custom keypads for adding more capabilities.

DFX’s SD-65 and SD-105 series CANbus based HMI displays utilize an optically bonded segmented LCD which high contrast is extremely readable even in direct sunlight, has instantaneous bootup time, and has an operating temperature of -40° to +80° C (-40° to 176° F). The displays are embedded inside a heavy-duty low-profile CNC machined aluminum housing and is available in multiple sizes, with optional function keypads, custom NEMA enclosures or a dash mount option which can be integrated into customer equipment.

Keyless Engine Start Lockout with PIN Protection

Having a mechanical key switch on your engine can be problematic if the key is lost, stolen or broken which can lead to expensive downtime. The new standard at DFX is KEYLESS which helps alleviate this problem. Simply press any button on the controller to wake up the system, press the start button and follow the LCD prompts to enter the PIN. For our SD-105A automatic engine start/stop applications a PIN is also requires enabling and disable automatic engine start/stop mode.

Customers who want a mechanical key switch can utilizes our optional software app in combination with the I/O inputs on the AE-120 to enable a mechanical key switch.

Throttle Control

DXF controllers use TSC1 (also called CANbus throttling) to support multiple throttle types which can be easily configured via the controllers integrated menu system. Engine speed is software controlled utilizing only the rabbit and turtle buttons on the controller’s membrane.

Supported Throttle Types

• Variable Speed
• 2-State Throttle
• 3-State Throttle
• 4-State Throttle
• Constant Speed

 

 

The default variable throttle uses the rabbit and turtle switches to adjust the desired speed between idle and the maximum programmed engine speed. The engine returns to idle on the next restart.

2-state, 3-state and 4-state throttle configuration uses up to four customer defined preset RPMs. Pressing the rabbit button selects the next higher preset and the turtle button selects the next lower preset. Constant speed runs the engine at a customer defined preset RPM.

Each controller auto detects TSC1 commands from an external device and disables conflicting messages from the controller. This eliminates problems that can occur when multiple TSC1 messages are sent and avoids having to manually disable the throttle function in the controller.

Function Keypad and Custom Membrane Graphics

Applications needed the ability to turn on and off optional auxiliary devices can use the SD-105 display module which supports up to four software-controlled function buttons. The function keypads are CANbus J1939 based and together with displays I/O or our optional AE-220 general purpose I/O module can turn on and off auxiliary outputs. Each function key be custom programmed as either latching, momentary or with an on-delay or off-delay timing function. Since our integrated keypads are CANbus based our function buttons could also be used to control engine functions such as custom RPM setting, activating engine cooldown, canceling engine cooldown or any other customer specific requirement. Each function key includes a bright red LED which indicates when function button is active. The standard SD-105 display buttons are marked with a generic F1, F2, F3 and F4, however custom graphics can be made available to the exact requirement of the customer with a one-time engineering fee and an annual commitment of 100 units.
