The Schindler 5500 relies on an integrated network of microprocessors communicating via a CAN bus system. Diagnostics are primarily performed through the board located in the control cabinet. Faults are categorized into three main levels: schindler 5500 error codes

Meaning: The light curtain or electronic safety edge remains blocked beyond a pre-programmed timeout period.

| Error Code | Description | Common Root Causes | | :--- | :--- | :--- | | | CAN Bus Communication Fault | Terminating resistor missing; wiring corrosion; faulty car controller board (PCB). | | BCI_OFFL | Building Communication Interface Offline | LON or BACnet gateway failure; IP network misconfiguration. | | NO_GRP | No Group Communication | Car cannot talk to the Group Controller (GC); check ring topology wiring. | | E-3122 | Car Positioning Lost | Encoder drift combined with missing correction zone magnets. |

Is the elevator ?

Inspect contactor tips for pitting, verify 24V DC coil voltage, and test helper contact blocks. Invalid Movement / Brake Slip

Check the door operator belt tension, door sill for debris, and the light curtain alignment. Drive Contactor Feedback Failure

Disclaimer: Elevator repair involves high-voltage electricity and heavy moving parts. This guide is for informational purposes by trained professionals. Always follow local safety codes (ASME A17.1 / EN81) and use proper lockout/tagout procedures. 1105 [Read Error Code via HMI/CADI] │ ▼
