Reset Button
Press the “Calibrate” button. Once pressed, the
calibrate LED should turn on.
Adjust the Deploy Limit potentiometer to the obstruc-
tion sensing level desired (see Figure S). Rotating
the potentiometer counterclockwise increases the
force that the ramp will exert when it is deploying.
Caution: Ensure that the force exerted is not exces-
sive. It is recommended to adjust the potentiometer
in small amounts and check operation after each
adjustment.
Adjust the Stow Limit potentiometer to the obstruc-
tion sensing level desired. Rotating the potentiom-
eter counterclockwise increases the force that the
ramp will exert when it is stowing.
Caution: Ensure that the force exerted is not exces-
sive. It is recommended to adjust the potentiometer
in small amounts and check operation after each
adjustment.
Once the desired force levels are reached, press the
“Calibrate” button a second time to store the set-
tings. Ensure the calibrate LED is off before return-
ing the ramp to service.
