Adjust Vertical Travel

WARNING: Be aware during the installation that this is a motorized device, and there are pinch points for people and for electrical wiring.

CAUTION: Vertical travel adjustment must always be made with the shelf in the middle of travel position and the power switch OFF.

There are two knobs for setting the travel limits, which are located at one end of the base controller housing (see Figure 15). The knob closest to the outside is the down stop limit adjustment. The knob closest to the center is the up stop limit adjustment

1.With the shelf in the middle of travel position and the power switch OFF, adjust the down limit to the desired height by turn- ing the down stop adjustment knob (clockwise = higher posi- tion, counterclockwise = lower position).

CAUTION: The unit must always be able to reach its own limit switches and turn itself off.

2.Check to be sure the limit switch stops the unit and the unit is not being stopped due to interference.

3.With the shelf in the middle of travel position and the power switch OFF, adjust the up limit to the desired height by turning the down stop adjustment knob (clockwise = higher position, counterclockwise = lower position)
