Technical Write-Up: Decoding and Resolving Schindler 5500 Error Codes

Step 3: Basic Reset (For Non-Safety Faults)

If it is a minor glitch (like a power fluctuation), you may attempt a reset:

1. Switch the isolation switch to "Off" for 10 seconds.
2. Switch it back to "On."
3. If the lift does a self-test and returns to service, monitor it closely. If the code returns within 24 hours, a hardware fault is likely.

4. Work Procedure for a Typical Error (Example: DRV 42)

Symptom: Elevator stops, displays DRV 42, will not move. schindler 5500 error codes work

Work steps:

1. Confirm code via SVT: check timestamp and frequency.
2. Physical check
   • Measure brake coil resistance (should be ~50–100 Ω depending on spec).
   • Check brake relay on controller (LED status).
   • Inspect brake lining for wear/drag.
3. Reset procedure
   • Power cycle the VOC (main disconnect → wait 30s → reclose).
   • Clear error memory via SVT command ERRCLR.
4. Test – Run inspection/low speed. If code returns, replace brake power board or brake assembly.

🛑 Safety note: Never bypass brake monitoring switches. DRV 42 can indicate actual brake failure – test brakes manually before resetting. Switch the isolation switch to "Off" for 10 seconds

Decoding the Schindler 5500 Error Code Structure

Schindler error codes are typically 4-digit numbers (e.g., 1201, 3403, 9102). The structure works like a map: 4 indicates an encoder issue

• First Digit (System Group): 1= Door operator, 2= Hoistway/door locks, 3= Drive/inverter, 4= Safety chain, 5= Communications, 6= Car operating panel, 8= Group control, 9= Power supply.
• Second Digit (Subsystem): 0 = General, 1 = Inputs, 2 = Outputs, 3 = Position reference.
• Third & Fourth Digits (Specific fault): Unique identifier for the exact condition.

Example: Error 3401 – The 3 indicates a drive fault; 4 indicates an encoder issue; 01 means “encoder pulse missing.”

3. Example Error Codes & Probable Causes

| Code | Description (field-known) | Likely Root Cause | |------|---------------------------|--------------------| | DRV 10 | 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 |
