Before troubleshooting specific codes, it is often necessary to attempt a system reset to clear transient faults.
Comprehensive Guide: Schindler 5500 Error Codes Verified & Troubleshooting
Check the safety circuit voltage across the landing door contacts. Clean and adjust contact pads to ensure deep mechanical bridging when closed. 3. Hoistway Position and Safety Circuit Faults
Occurs when the elevator car is level, but the door limits indicate it is "open and closed" simultaneously. Adjusting the door operator limits usually resolves this. KB / KB1 Fault: schindler 5500 error codes verified
| Code / ID | Short description | Likely cause(s) | Recommended corrective action | |---|---:|---|---| | 99 | Faulty relay feedback (RSK / RSK1) | Faulty relay(s) or feedback wiring | Inspect/replace RSK/RSK1 relays; check wiring and connectors; reset per procedure | | 4305 | Overshoot / limit / final switch fault (example from field report) | Final/top limit not responding or mis-adjusted; limit switch wiring | Check final/finial limit switches, mechanical adjustment, safety chain; clear and single-reset per manual | | 1475 SW_BlockPerm (or similar SW fatal) | Fatal software error / block | Corrupt SW state or parameter mismatch | Download error logs, check software/board versions, contact field support if needed; perform safe reset | | 1476 DataDestroyed / Illegal data | Corrupt parameter or memory | Parameter corruption, failed write | Restore valid parameters (backup), reparameterize, run parameterization procedures | | VF_StartError / VF_ShortBreak / VF_StopSpeed (VF drive errors) | VF drive fault (drive blocks, stopping issues, short brake) | Incorrect drive parameters or braking config | Verify VF software/version, check BARMAG/first-brake parameters via CADI/SMLCD, adjust and re-run tests | | WATCHDOG ON / Fatal VF internal | VF watchdog / internal VF fault | Software mismatch, internal VF fault | Verify VF SW version, download logs, upgrade or reflash VF if supported; escalate to drive/field support | | DC-Link Test aborted (e.g., 4765) | DC link / capacitor / chopper issues | Safety circuit open, DC link units faulty | Check safety circuit contacts T1–T6, DC-Link components, capacitors, braking chopper; re-run DC-Link test | | Parameter OK / ERROR (parameter implausible) | Invalid or missing parameters | Parameterization not executed or parameters invalid | Execute Parameterization routines (e.g., Motor Control); load correct parameter set | | Safety chain / safety circuit open (various safety codes) | Safety circuit not closed | Open safety contact, wiring, safety device trip | Inspect safety chain and all safety contacts; remedy and verify LEDs/status; follow lockout/tagout | | End / Final limit / Safety End faults | Counterweight buffer/safety switches triggered | Misadjusted buffers, tripped switches, mechanical interference | Inspect buffers, reset switches, inspect travel and safety devices | | VF Watchdog / Fatal internal logs | Drive software/hardware fault | Firmware mismatch or internal error | Capture logs, note versions, escalate to field support / R&D drive team |
Drive errors usually point to the regenerative drive system, inverter modules, or the permanent magnet motor.
Check motor insulation resistance (megger test). Verify brake release timing; if brakes do not lift before the motor draws torque, current spikes occur. Error Code: 0302 (Overvoltage) Before troubleshooting specific codes, it is often necessary
⚠️ : Elevator maintenance should only be performed by certified technicians. Attempting to clear safety-related faults without addressing the root cause can lead to equipment damage or injury. To help further, could you tell me:
| Error Code | Short Description | Verified Cause | Recommended Action | | :--- | :--- | :--- | :--- | | | InvCarPos (Invalid Car Position) | The actual car position read from the encoder is outside the learned range of floors. | Perform a learn trip to recalibrate the floor positions. | | 1502 | Position Jump | The software calculates a position change of over 240mm between two readings (10ms apart). | Check for EMC problems or faulty wiring; replace the position encoder if necessary. | | 1505 | InvFlPosTrp (Invalid Floor Position during Trip) | An inconsistency with floor positioning was detected while the elevator was moving. | This error is often linked to 1501 and 1502 ; perform a learn trip and check the encoder. | | 212 | Door Opening Error | The door cannot open due to repeated activation of the KOKB (door opening force limiter). | Check the door lock and mechanical door operation. | | 99 | Unspecific Persistent Error (e.g., 4305) | This is a fatal error that blocks the control system until manually reset. The specific cause (like error 4305 ) is logged elsewhere. | Perform a manual reset on the controller. Avoid multiple resets, which can exacerbate the issue. |
Remedy: Inspect the dynamic braking resistors for open circuits or verify the grid tie-in line voltage. KB / KB1 Fault: | Code / ID
Issues with speed, brake operation, or motor feedback.
Safety circuit violations, processor failures, or drive failures that stop the elevator instantly.
Similar to E12, this indicates an open safety circuit component (e.g., K-SF2000 safety switch).
: Press the reset button on the GCIOCF PCBA once and wait for the control system to reboot.
The car traveled past the terminal landing and struck the physical limit switch.
