This document is a service manual for the BraunAbility NL500 Series 02 wheelchair lift, covering serial numbers 1412270001 to 15042400070 and Revision A. It provides comprehensive information for installation, operation, maintenance, and repair of the device.

Function Description:

The BraunAbility NL500 is a platform lift designed for public use vehicles, ensuring compliance with FMVSS No. 403 "public use lift" requirements. It can be installed on buses, school buses, and multi-purpose passenger vehicles (excluding motor homes) with a gross vehicle weight rating (GVWR) exceeding 4,536 kg (10,000 lb). The lift facilitates the entry and exit of individuals using wheelchairs by providing a stable, movable platform. Key operational features include:

Stow/Deploy: The lift can be stowed (folded) or deployed (unfolded) using hydraulic cylinders.
Raise/Lower: The platform can be raised to floor level or lowered to the ground.
Inner Roll Stop: An inner roll stop deploys to secure the wheelchair on the platform when raised.
Outer Barrier: An outer barrier deploys to secure the wheelchair on the platform when lowered.
Hand-Held Attendant's Control Pendant: Allows for manual control of lift functions (UP, DOWN, STOW).
Interlocks: The lift incorporates safety interlocks to prevent vehicle movement unless the lift door is closed and the lift is stowed. It also prevents lift operation unless the vehicle is stopped and movement is prevented.
Occupancy Sensors: Sensors prevent the platform from folding/stowing if occupied, and prevent the inner roll stop or outer barrier from raising if occupied.
Platform Lighting: Provides illumination when the lift is deployed, and the pendant is illuminated when powered.
Audible/Visual Warnings: Activates if the threshold area is occupied when the platform is below floor level.
