Press the Esc button until you reach the root directory.
Do not rely solely on the active code. Access the error history menu on the SMLCD to see what secondary errors occurred immediately prior to the shutdown. This often points to the root cause rather than a consequential failure.
Cause: Pitted or dirty contacts on a landing door interlock, or loose wiring in the car gate switch. schindler 5500 error codes
Meaning: The controller lost track of exactly which floor the elevator car is occupying.
If any adjustments were made to the position reference system (vanes, magnets, or encoder), or if a "1501" or "1502" error is present, a learn trip is mandatory to recalibrate the system's floor map. This is a controlled, low-speed run of the car from the bottom to the top floor to teach the controller the exact positions. Press the Esc button until you reach the root directory
If you are a building owner or facilities manager and see persistent error codes, contact your local branch immediately. Do not attempt internal repairs unless you are a certified elevator technician.
The Schindler 5500 typically utilizes variations of the or CO_DI (Controller Digital) platforms, integrated with the CADI (Computer Aided Diagnostics Instrument) interface. The system communicates via a high-speed CAN-bus (Controller Area Network) system that connects the main controller board, car operating panel (COP), landing operating panels (LOP), and the drive system. Accessing the Error Log via HMI / SMLCD This often points to the root cause rather
The SETT connects to the elevator's controller (often the CO MX) to display active fault codes, review historical error logs, and perform critical commands like running a learn trip for position calibration. Without this tool, diagnostics are severely limited. It is the conduit through which all system data and error information flows.
Solution: Check the 5V and 24V DC power supply rails. Check grounding connections. Update firmware if the error is recurring.
