Manual Calibration Instructions for Controller

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.
