The Energize III all-electronic brake controller features a patented sensing device that automatically monitors and measures tow vehicle deceleration and applies the trailer brakes in direct proportion. It reacts instantly to any change in brake pedal pressure and ensures controlled, smooth stops. Trailer and tow vehicle stoplights operate automatically when the manual lever or trailer brakes are applied.

Mounting Angle and Mounting Direction

Mounting angles between –35 and + 90 degrees can be accommodated by the controller. The unit must, however, be installed so that it is parallel with the travel of the tow vehicle and trailer. Use the included reversible slotted mounting bracket and machine screws and fasteners to mount your controller with the back of the controller toward the front of the vehicle. Always be sure to mount in a location which allows the driver to easily apply the manual override and to see the red indicator light.

User-Adjustable Braking Power

During braking, the trailer brakes will work in direct proportion to the tow vehicle braking effort. The more deceleration detected by the pendulum sensor, the greater the amount of power delivered to the trailer brakes. The Energize III's red indicator light will illuminate from dim to bright during the stop and will return to dim when deceleration is no longer detected. When the tow vehicle brake pedal is released, the controller and red indicator light will be turned off. The gain wheel can be used to adjust the amount of power to the trailer brakes to increase or decrease your stopping power as needed. It is responsible for obtaining a smooth, proportional, and optimum tow vehicle and trailer brake response. To increase the amount of current required, rotate the gain wheel upward toward the top of the case. To decrease the amount of current required, rotate the gain wheel downward toward the bottom of the case.

Manual Operation and Override

The Manual Slide Lever is located on the front right side of the controller. The further the manual slide lever is moved from the right to the left, the greater the amount of trailer braking power. The manual slide lever operation is an independent circuit and overrides the gain wheel adjustment to allow full braking effort when required. Use the Manual Slide Lever to apply the trailer brakes independently of the tow vehicle brakes or to override the automatic trailer brakes when more braking or less braking is required. The manual slide lever is used in emergency stop situations when more braking may be required than is available with the power wheel adjustment or for control of excessive trailer sway. The indicator light will illuminate from dim to bright as the manual lever is applied and remains off when the manual lever is released. The tow vehicle and trailer brake stoplights will still illuminate during the manual lever activation.
