Pro-Tip for the Schindler 5500

Unlike older hydraulic units, the 5500 hates "dirty" power. 40% of intermittent "Top" error codes vanish after verifying the grounding on the controller cabinet and checking the phase monitor relay.

3. Code 0415 – Position Lost (PPR – Pulse Pattern Reference)

Status: High Severity – Can Cause Free Falls to Safety Gear schindler 5500 error codes top

Description: The elevator controller lost synchronization between the car’s calculated position (based on encoder pulses) and the position reference system (magnetic tape or selector vanes in the hoistway). Useful article: "Schindler 5500 — Top Error Codes

Common Causes:

• Slippage of the main traction sheave rope (uneven tension)
• Faulty incremental encoder (often mounted on the motor’s tail shaft)
• Damaged or demagnetized position tape (Schindler’s Magnetic Absolute Positioning System - MAPS)
• Power glitch resetting the RAM position counter

Troubleshooting Steps:

1. Perform a Hoistway Learning Run (autotuning) from terminal to terminal.
2. Check the encoder coupling for play or cracks (a frequent issue on high-mileage units).
3. Verify the air gap between the position reader head and the magnetic tape (1.5–2.5 mm).
4. Inspect the governor rope for slippage – it correlates with position feedback.
