: Safety circuit open or door safety circuit opened during travel. 13 : Error in the normal door opening sequence. Safety & System Blockage Errors
Intermittent call registration. Car shows "Out of Service" but resets after power cycle.
: Trip timeout; the car did not reach the desired floor within the maximum allowed time.
These errors relate to the main processor board (e.g., GCIOB, SMIC) or software synchronization issues. schindler 5500 error codes
The positioning system registers a speed exceeding the rated velocity or the deceleration curve limits near terminal floors, triggering an emergency electrical stop. 4. Communication and Bus Faults (BIO Bus / CAN Bus)
Cause: Actuation of pit switch, buffer switch, car top stop switch, or governor overspeed switch.
: Discrepancy between calculated and actual car position. Potential causes include slipping belts or a loose motor encoder. 0450 - Releveling Failure : Safety circuit open or door safety circuit
Issues with door operation are among the most frequent causes of elevator downtime. : Door position recovery failure. 0353 / 0354 : Door unavailable or availability recovered.
For detailed technical diagrams or specific part numbers related to these codes, you may want to consult a certified technician or refer to the official Schindler Technical Knowledge Center for a particular error code?
service tool) and relate to the inverter (VF drive) and motor operation. 0004 - Invalid Movement Car shows "Out of Service" but resets after power cycle
This is a common "phantom" fault where the lift might stop or show a maintenance symbol. It often indicates that the system date and time are incorrect or have drifted. Resetting the date in the main menu parameters often clears this according to technician reports .
: A critical safety circuit issue where the 110V safety chain is interrupted. Even if 110V is measured, a missing ISK signal prevents the elevator from moving.
If you encounter intermittent communication errors across multiple modules, check the termination resistors on the CAN-bus network. The resistance between CAN_H and CAN_L with the system powered down should ideally measure around 60 Ohms (two 120-Ohm resistors in parallel at each end of the bus).
These errors generally prevent the elevator from starting any trip. 01 - Safety Circuit Open
Ensure the controller firmware is updated to the latest version recommended by Schindler to resolve known software bugs and improve diagnostic accuracy.
