Braun 33657 DOT - Public Use Lift, Ground Sense Calibration, Outer Barrier Occupied Calibration

Braun Corporation FMVSS No. 403 Quick Reference Installation Sheet 33675 Rev. A

4 Calibration and Floor Level Adjustment

5 FMVSS 403/404 Certification Checklist

Platform Sense Calibration

1.There must be no weight on platform.

2.Press hand-held pendant UP switch to raise platform a minimum 3" above stow level.

3.Press and hold control board 50# CAL. button. While pressing the 50# CAL. button, press and hold the hand-held pendant STOW switch (button). The platform will lower to stow level (begin stow function), and then start to raise. Release 50# CAL. button immediately when platform starts to raise from stow level.

4.After calibration, the LCD screen should read “PF OCCUPIED” whenever there is 50 lbs. or more present on the platform. The 50 pound platform sensing is now calibrated.

Ground Sense Calibration

1.Press hand-held pendant DOWN switch to lower platform fully to ground level.

2.While continuing to press the pendant DOWN switch, press and then release the control board O_BAR GND. button.

3.Release the pendant DOWN switch.Ground level sensing is now calibrated.

DOT — Public Use Lift

Public use vehicle manufacturers are responsible for complying with the lift lighting requirements in Fed- eral Motor Vehicle Safety Standard No. 404, Platform Lift Installation in Motor Vehicles (49 CFR 571.404).

Inner

Roll Stop

1.Press hand-held pendant DOWN switch to lower platform fully to ground level.

2.Once outer barrier is fully unfolded (ramp position), release the pendant DOWN switch.

3.Press and hold the control board O_BAR GND. button. While holding O_BAR GND. button, press hand-held pendant UP switch to raise the outer barrier. Be sure to release O_BAR GND. button when outer barrier reaches approximately half full up (vertical) position.

4.After calibration, the LCD screen should read “OUT-BAR OCCU- PIED” whenever there is weight present on the outer barrier.

Platform

Dual

Floor Level Switch

The Floor Level switch stops upward travel of the platform during the Up function (activated by the torque tube-mounted Floor Level cam). Position the lift platform 1" above �oor level using the manual operation system (detailed on opposite side of this sheet). Loosen the clamp securing the torque tube-mounted Floor Level cam. Rotate the cam until the Floor Level switch is activated (cam depresses switch).

Note: Check the �oor level position of the platform and the inner roll stop after powering the pump. Hydraulic pressure may affect platform height slightly. Fine tuning adjustment (tweaking) of the Floor Level switch may be required.

The inner roll stop must rest properly on the vehicle �oor when the lift is deployed. Adjust the inner roll stop only if necessary (refer to the service manual).

Floor Level Cam Floor Level Switch

Torque Tube Cam depressing switch.

The operations listed below must be functionally veri�ed.

Vehicle movement is prevented unless the lift door is closed, ensuring the lift is stowed.

Lift operation shall be prevented unless the vehicle is stopped and vehicle movement is prevented.

The platform will not fold/stow if occupied.

The inner roll stop will not raise if occupied.

The outer barrier will not raise if occupied

Outer Barrier

Verify platform lighting when lift is deployed and pendant illumination when lift is powered.

A visual and audible warning will activate if the threshold area is occupied when the plat- form is at least one inch below �oor level.

Platform movement is prohibited beyond the position where the inner roll stop is fully deployed (up).

Lift platform movement shall be interrupted unless the outer barrier is deployed (up).
