The Perpetual Motion Enterprises (PME) Seat Function Screen/Controller (Model/Part Number: m90S-1529) is a specialized power wheelchair electronics component designed to operate auxiliary seating functions. Manufactured by Perpetual Motion Enterprises, this unit interfaces directly with the chair's core power module to distribute current to heavy-duty actuators, allowing the user to control positional adjustments like tilt, recline, leg rest elevation, and seat lift. 

Core Technical Specifications

  • Model Number: m90S-1529
  • Manufacturer: Perpetual Motion Enterprises Limited (PME)
  • Operating Voltage: 24V DC standard power wheelchair configuration
  • Control Configuration: Multi-channel actuator routing architecture
  • Interface Ports: Standard multi-pin connectors paired with standard auxiliary control inputs (such as 1/8" phono or 9-pin joystick pass-through links). 

Functionality & Wheelchair Integration

PME hardware specializes in translating drive control inputs into motorized seat adjustments: 
  • Actuator Distribution: The module safely accepts high-current power from the main batteries and gates it directly to individual seating motors based on joystick command profiles. 
  • Drive Lockout Safety (SMARTS): Incorporates dedicated safety limits—such as electronic tilt/tipsy sensors—to prevent the wheelchair from driving at full speed (or driving at all) when the seat is unsafely tilted, reclined, or elevated.
  • Cross-Brand Electronics Compatibility: This component is widely utilized by major high-end rehab wheelchair brands including Quickie (Sunrise Medical), Quantum Rehab (Pride Mobility), and Motion Concepts / Invacare setups to manage complex, multi-power seating packages.
