The Marantec Position Box MDF AWG is a position monitoring unit designed for MDF-series industrial door operators. It provides accurate door position feedback to the control system, ensuring reliable automation and safe door movement.

Core Function (AWG Position System)

The AWG (Absolute Encoder) replaces mechanical limit switches and provides:

• Absolute position detection (no loss of position after power failure)
• Electronic limit setting (OPEN/CLOSE positions)
• Intermediate position programming
• Direction monitoring & correction
• Adjustable force/power limits

 From Marantec specs:

• Intermediate position programmable
• Rotation direction monitoring
• Adjustable power limitation
• Electronic end-position setting via encoder

Control & Position Box (CS320 / similar)

The “position box” is typically the Marantec control unit (e.g., CS 320) paired with AWG.

Key Control Features

• 4 programmable relay outputs (44 functions)
• 2 programmable inputs (27 functions)
• Integrated cycle counter
• Maintenance alarm (PIN protected)
• Error memory with diagnostics
• LCD interface (optional)

Safety & Monitoring

• Closing edge protection (multiple types)
• Light barrier integration
• Safety circuit inputs
• Brake control & monitoring
• Compliance with EN 12453 safety standards
