Microswitches - BraunAbility Foldout Ramp Maintenance And Service Manual

Ramp Microswitch Adjustment
The ramp motor assembly is equipped with two
microswitches, the deploy microswitch and stow
position microswitch.
The deploy microswitch cuts the ramp motor
when the platform reaches a position where the
ramp will complete the deploy function by the
force of gravity (ramp to ground level).

Stow Position Microswitch Adjustment: An ad-
justment screw moves the position of the stow po-
sition slider assembly inward and outward. Turn
the screw clockwise to adjust the ramp stowed
position inward. Turn the screw counter-clock-
wise to adjust the ramp position outward. Ensure
the ramp does not obstruct the power slide door
(check per following procedure).
Door Obstruction: Manually open the slide door
fully. Move the top of the ramp out slightly until the
ramp enters the path of the door. Press a control
switch. Caution: Observe and stop door if ramp
does not stow fully to avoid damage. If the ramp
stows fully and the door closes, the microswitch
Kneel Microswitches
position microswitches (not adjustable). A bracket
(vertical tab) at the end of the actuator shaft trips the
microswitches as the shaft extends and retracts. If
the kneel switches are not activated (tripped), the
kneel actuator will clutch (ratchet) continuously for
approximately 10 seconds at end of actuator travel.
The stow position microswitch determines the full
stow position (how far the ramp stows inside the
vehicle).
Remove the ramp motor assembly interior cover
to access microswitches (located rear of the pas-
senger slide door). Note: It is not necessary to
remove any other interior panels.

is adjusted properly. If the door contacts the ramp,
the stow microswitch needs to be adjusted inward.
Adjust microswitch slider slightly and repeat proce-
dures.
Deploy Microswitch Adjustment: The deploy mi-
croswitch is cam activated. The microswitch is se-
cured with two mounting screws. The microswitch
can slide in a rotary motion to change it's position
is relation to the cam. The deploy microswitch cuts
power to the ramp motor, allowing the ramp to grav-
ity down and complete the deploy function. Adjust
the switch to allow gravity to complete the deploy
operation. Ensure the ramp motor shuts off before
the ramp reaches the horizontal position or below.
Kneel Actuator Access: Remove the kneel as-
row seats. See Switch and Component Location
Diagram.
Note: Changing the kneel chain length is prohib-
ited.
