Determining the Mounting Position of the Controller and Rear Sensor
Controller
The controller has a limited mounting area for
proper performance. At the center of the frame
(signified by the blue dotted line in Fig. 3) and
at the center of the landing gear (signified by
the black dotted line) is a center point. From
this center point the controller can be mounted
12" out on either side and up to 3' in front of or
behind the center point, while still being inside
the compartment. This area is signified by the
green dotted box labeled Section A in Fig. 3.
Rear Sensor
The rear sensor MUST be in line with or behind
the rear leveling jacks, as signified by Section
B in Fig. 3. Both the front sensor and the rear
sensor MUST also be mounted in line with the
center of the frame, as signified by the dotted
blue line in Fig. 3.
Measuring Departure and Approach Angle
Departure and approach angles are measured by
running a string line from the meeting point of
the tire and ground up at an angle to the lowest
point on the front or rear of the trailer. These
string lines are shown as dotted lines (Fig. 4).
