AIRSTREAM INTERNATIONAL TRAILER
Important Facts to Remember
1. Do not mount or activate RF generating items (cell phones, two way radios) near (less than 12") the
brake control.
2. Reversing the connection to a breakaway battery on the trailer will destroy the brake control.
3. Disconnect trailer plug from the tow vehicle prior to testing a breakaway switch, or you may destroy the
brake control.
4. The light is:
•
GREEN when trailer is connected.
•
RED when brake pedal or manual is activated and trailer is connected.
5. The GREEN light draws 10 milli-amperes of current from tow vehicle. It would take over 5,000 hours to
drain the tow vehicle battery.
6. The level adjustment is CRITICAL. The level adjustment determines whether automatic braking
response is delayed or aggressive,
7. This brake control is activated by inertia. It senses deceleration and generates an output that reflects the
inertia sensed. In a stationary state, the brake control will not apply the trailer brakes unless the Manual
Slide Knob is actuated.
NOTE: Electronic Brake Controls must be mounted from -20 degrees nose down to 70 degrees nose up.
(See above.) Failure to install brake control within these constraints may cause your control to become
inoperable.
Leveling the Sensor
After the brake control has been securely mounted the level adjustment must be set.
Electronic brake controls are activated by inertia and require the level to be set properly, or the braking
response will be too harsh or ineffective. To properly level the sensor, the trailer and tow vehicle must be
parked on a level surface and trailer must be connected to tow vehicle.
1. Connect trailer to tow vehicle, Bi-Colored Light should glow GREEN.
2. Set power knob to maximum by fully rotating clockwise
3. Depress tow vehicle's brake pedal and hold.
4. Rotate the Level Knob counter-clockwise (towards the back of the control) until the Bi Colored
Light starts to change colors from GREEN to RED.
5. Carefully rotate the Level Knob clockwise (towards the front of the control) until a shade of
ORANGE is visible.
•
Bi-Colored Light should show:
•
DIM ORANGE for a typical setting. BRIGHT ORANGE for an aggressive setting.
•
DIM RED for a more aggressive setting.
NOTE: Range of adjustment for the level knob from DIM ORANGE to DIM RED is 20 degrees of
rotation.
6. Release brake pedal.
NOTE: When the brake control is leveled properly there will be very little current flowing through the
brake magnets in a static state with the foot pedal depressed. The brake magnets will hum when there is
current flowing through them. Anytime the Bi- Colored Light shows any color other than GREEN, there is
current flowing through the brake magnets.
