Many 5500 errors (like 709/1680) can be triggered by "belt bounce" or tension issues, even if no one is in the car.
While exact numerical sequences can vary based on the specific software version installed, Schindler modular controls categorize errors into distinct functional blocks. 1. Safety Ring and Chain Failures

E03 — Safety circuit / relay trip
For detailed calibration of the load weighing system, refer to the Schindler 5500 LMS Adjustment Guide .
Usually appears after a 709 error. Resetting the controller often clears it temporarily, but check the safety switches (like the governor tension switch). IDC Sensor/Leveling Issue
Keep a physical logbook in the machine room. Note the timestamp, car load, and floor position for every error code. The pattern (e.g., E-4213 only occurs when passing floor 12) is often more valuable than the code itself. schindler 5500 error codes
The inverter heatsink or motor temperature exceeds safe operating thresholds.

This critical safety error is logged when the system detects an impossible jump in the car's position. The software calculates the position every 10 milliseconds; if it sees a "jump" exceeding 240mm in five consecutive readings, it triggers an emergency stop and permanently blocks the elevator.
Located on the main control board in the controller cabinet.
