| Code | Description (field-known) | Likely Root Cause | |------|---------------------------|--------------------| | | Drive overcurrent | Short in motor windings, failing IGBT module | | DRV 21 | Encoder loss of signal | Incremental encoder dirty/broken, cable loose | | DRV 42 | Brake not released | Brake coil failure, bad relay on brake board | | IO 103 | Door lock circuit open | Defective door lock switch, wiring break on landing | | IO 201 | Car call button stuck | Contaminated COP button (coffee, mechanical jam) | | SAFETY 07 | Overspeed governor tripped | Mechanical reset needed; rope slip or excessive speed | | CAN 05 | No communication with car | Loose CAN connector in traveling cable | | POS 03 | Missing magnet reference | Position magnet missing/demagnetized on rail | | OPB 14 | LCD display timeout | COP display board power issue or flat cable loose |
Frequently follows a 709. It usually requires a system reset (101 reset) via the SMLCD. schindler 5500 error codes work
Identify the code on the main PCB display. Is it steady (latched) or blinking? | Code | Description (field-known) | Likely Root
Schindler 5500 error codes function through the , which displays alternating four-digit error IDs and status messages to indicate system faults. These codes allow technicians to pinpoint issues ranging from safety circuit interruptions to traction media (STM) aging. Essential Schindler 5500 Error Codes & Meanings Is it steady (latched) or blinking
The most common "halt" code. Indicates a break in the safety string. Check all landing door interlocks and car-top stop switches.
