In addition to numerical codes, the controller uses LEDs (such as on the SMIC or SCIC boards) to signal status: Schindler Elevator Error Codes Guide | PDF | Electric Motor
Brake switch feedback error. Common issue where switch feedback does not match the command. DirectionErr schindler 5500 error codes free
| Code | Description | Probable Cause | Free Fix / Check | | :--- | :--- | :--- | :--- | | | Drive Overcurrent | Short circuit in motor windings or brake coil. | Measure resistance across motor phases (U,V,W). Check brake release relays. | | TE-3012 | DC Link Overvoltage | Regeneration overload or bad braking resistor. | Check the braking resistor (DBR) for open circuit or cracks. Check incoming AC line voltage. | | TE-4015 | Drive Undervoltage | Mains supply dropout or faulty rectifier. | Check 3-phase input fuses. Measure voltage during building heavy load (HVAC startup). | | DQ-102 | Speed Feedback Loss | Encoder on the gearless machine failed. | Check encoder wiring for chafing. Clean the encoder lens (if optical). | | DQ-880 | Drive Overtemperature | Cooling fan failure or dirty heat sink. | Clean the controller air filters. Verify the cabinet fan (FAN1) spins freely. | In addition to numerical codes, the controller uses
: Overtemperature warnings for the motor or drive system, respectively. | Measure resistance across motor phases (U,V,W)
The following codes are frequently encountered during maintenance of the 5500 and 6500 series:
: Press the reset button once, wait until the red LED turns off, then press it again.
