Hayes Blackbird Brake Controller 81726
The Blackbird is the
ultimate in digital time-based trailer braking--giving you big power in the
palm of your hand. The Blackbird operates seamlessly with electric and
electric-over hydraulic braking systems and does not interfere with anti-lock
brakes, cruise control, or other electrical systems on your vehicle.

Automatic Operation with
Digital Display and Sleep/Standby Modes
During braking, the
Blackbird operates on a time-based circuitry design. The “power ramp time” and
power is adjustable to achieve trailer brake responsiveness. 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 in
“stand by” mode, the controller will display two dots. After 10 mins it will go
to “sleep mode”, the display will shut off.
Adjustable Power Ramp
Time
The Controller applies
power to the trailer brakes based on a time-based circuitry. The adjustable
Power Ramp Time is the elapsed time from the point that the brakes are first
applied until the point that the power level reaches its maximum. The Power
Ramp Time can be adjusted (0.5-5 seconds at 99% Power Setting) to obtain
optimum trailer brake responsiveness between the tow vehicle brakes and the
trailer brakes. Simply slide the “Power Ramp Time Setting” towards the rear to
increase the ramp time (slow ramp), or towards the front to decrease the ramp
time (faster ramp).
Maximum Power with
Automatic and Manual Settings
Under 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, or 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.
