## Description

Product Description               Digital, proostional, accelerometer brake controller designed for use on single, tandem, tri or quad braking trailers. Digital, diagnostic read-out. No level adjustment required.                  .com               The Genesis lets you apply full power in emergency stopping situations. The three-axis accelerometer technology automatically levels and senses the rate of deceleration. The Genesis Brake Controller features automatic and manual settings and provides superior braking response when towing single and quad axle trailers. Superior braking response with automatic and user-adjustable power settings Key FeaturesExclusive Quik-Connect featureFor all single and quad axle trailers equipped with electric brakesFull 12-volt output provided with manual lever activationSuperior responsivenessCompatible with all electronic systems (ABS, cruise, etc.)Wide range of mounting positions; perfect for steep dash surface mountingEasy adjustment and standard four-wire hookupRed L.E.D. indicator displays braking intensity and warns of short circuitAutomatically adjusts to road conditions and changes in braking situationsEasy to read digital displayBoost Feature gives you the ability to apply more initial braking power when towing heavier trailersFor use with electric and electric-over hydraulic braking systemsMounting 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. Automatic Operation with Digital Display and Standby ModeDuring braking, the Genesis senses deceleration of the tow vehicle. An internal sensor measures the amount of deceleration and sends a proportional amount of power to the trailer brakes. The maximum braking supplied depends on the set up of the controller. The digital display will indicate the amount of power being sent to the trailer brakes. Once the brake pedal is released, the unit will return to “stand by” mode. While standing by, the controller will display the currently selected mode of display (% power, voltage, or current).Maximum Power with Automatic and Manual SettingsUnder automatic braking (via brake pedal), the maximum power is the percent of available power that is sent to the trailer brakes. Under manual override (via manual slide lever), the maximum power is the percent available power that is sent to the trailer brakes when the manual slide lever is moved all the way to the left. Choose Automatic Maximum Power settings to use the factory pre-set of 50% Maximum Power, or adjust the settings to your preferred amount of braking power. Use the Manual Override slide lever to apply the trailer brakes independently of the tow vehicle brakes or to override the automatic trailer brakes when less braking is required. The Manual Override slide lever can be used for emergency stopping or for control of excessive trailer sway. The tow vehicle and trailer brake stoplights will still illuminate during the manual lever activation.
