Schindler 5500 error codes are diagnostic signals used to identify specific mechanical or electrical issues within the elevator’s Travel Control or Miconic systems. These codes appear on the SMLCD (Schindler Machine LCD) or the controller display to assist technicians in rapid troubleshooting. Common Schindler 5500 Verified Fault Codes

The following list identifies frequently encountered error codes for the 5500 and 6500 series:

0003: NoKSE_STDSTL – No KSE signal (shaft limit sensor) detected while the car is at a standstill.

0004: InvldMovement – Invalid movement detected; the controller sees encoder activity while the car should be stopped, often due to brake drift.

0005: SH_on_STDSTL – The SH (Main Contactor) feedback is active while the elevator is at a standstill. schindler 5500 error codes verified

0006: SB_on_STDSTL – The SB (Brake Contactor) feedback is active during the stop phase.

0007 / 0008: SH_Fault / SB_Fault – General failure of the Main or Brake contactors, often requiring a safety circuit check.

0009: KB_Fault – Brake contact feedback (KB/KB1) did not switch correctly; may indicate a broken contact or adjustment issue.

0013: OverSpeed – The car has exceeded the rated speed limit.

0020: PositionLost – The system has lost track of the car’s position in the shaft, typically requiring a reset or relearn run.

0028: OverTempMotor – Motor thermal contact has opened due to overheating; check ventilation and current. Critical System Diagnostics Drive and Power Errors

0441: Drive Overtemperature – The drive unit is too hot; check fans and ambient machine room temperature.

0447: Excess Encoder Deviation – Significant difference between commanded and actual position; check for slipping belts or loose encoders.

0448: Drive Inverter Failure – Internal hardware failure within the drive inverter. Load Weighing (LMS) Errors

1105 / 1109 / 1110: The Load Weighing Device requires calibration. 1120: Load weigh signal is missing.

Frequency Check: For the LMS system, Frequency 1 and 2 should ideally read 16500Hz ± 700Hz when checked via the SMLCD. How to Perform a System Reset Verified Schindler 5500 Error Codes The Schindler 5500

If the elevator is blocked (Status "B"), a technician may perform a 101 Reset or a soft reset to clear non-critical faults:

Access the SMLCD on the controller or the car top inspection box. Navigate to the Reset menu.

Perform a "Soft Reset" or a "101 Reset" to cycle the software.

For hardware resets, switch off the main power supply and battery supply, wait 5 seconds, and then power back on.

⚠️ Warning: 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:

What specific error code are you currently seeing on the display?

Is the elevator currently operational, blocked, or stuck between floors? Do you have access to the SMLCD tool or Section 7 - Troubleshooting

5. Communication Bus Errors (CAN/Serial)

| Code | Description (Verified) | Common Cause | Recommended Action | |------|------------------------|---------------|---------------------| | E-5001 | CAN bus off – drive to SMIC | Terminating resistor missing or bus short circuit | Check bus termination (120 ohms); inspect for chafed wires. | | E-5005 | Group controller communication timeout | Bad connection in group network (3+ cars) | Reset group controller; check repeater modules. | | E-5012 | SMLCD service tool no response | Corrupted firmware or dead LCD | Reflash firmware; replace service tool interface. |

1. Introduction

The Schindler 5500 is a gearless traction elevator equipped with the Miconic MX microprocessor controller. Error codes are displayed on the LMS (Local Monitoring System) or via the SML (Schindler Mobile Link) diagnostic tool. Codes are grouped by subsystem: drive, door, communication, safety chain, and position reference.

How to Verify Schindler 5500 Error Codes on Site

To ensure you are working with Schindler 5500 error codes verified in real time, follow this step-by-step procedure:

Conclusion: Trust but Verify

The Schindler 5500 is a robust system, but its error codes are tools, not verdicts. Always prioritize verification over assumption. A "verified" code is not just a number on a screen; it is a cross-referenced, time-stamped, mechanically confirmed symptom. Error Code 1: Motor Overload

Your Action Plan:

  1. Download the official Schindler 5500 Field Fault Matrix (Appendices D-G).
  2. Always log the time and frequency of the code before resetting.
  3. If a code returns after three resets, stop cycling power. You are burning contactors. Call a certified Schindler Modernization technician.

Disclaimer: Only licensed elevator technicians should access the Schindler 5500 controller. Improper resetting can violate ASME A17.1/CSA B44 safety codes. This article is for informational verification purposes only.

Schindler 5500 error codes are primarily accessed and monitored through the SMLCD (Schindler Machine LCD) interface, where they often alternate with system status messages. Common faults for this series involve door positioning, traction media monitoring, and safety circuit interruptions. Common Schindler 5500 Error Codes Description Possible Cause Recommended Action 0004 Invalid Movement Movement detected while car should be idle Check brake or machine for drifting. 0005 SH_on_STDSTL SH or SH1 contactor feedback invalid for idle state Inspect auxiliary contacts of SH/SH1. 0352 Door Pos Recovery Fail Failure to recover door position Check door operator and sensors. 0430 Brake Switch Mismatch Brake switches don't match commanded state Check brake switch wiring and state. 0435 Motor Overtemp Motor temperature too high Allow motor to cool; check ventilation. 0447 Excess Encoder Dev Deviation in encoder position Inspect for slipping belts or loose encoder. 0449 Drive Output Failure No output detected despite command Verify drive power and inverter state. 0522 TMAgingClckE Traction media aging clock error Verify and set the correct system date/time. Verified Troubleshooting Steps

System Reset: You can perform a "Single Reset" by pressing the reset button on the GCIOCF PCBA once. A "Double Reset" (waiting for the red LED to turn off before the second press) re-initializes the entire elevator control.

Safety Circuit Issues: If the safety circuit is open, the elevator will not start. Verify the safety loop and landing interlocks (KTS).

LMS Adjustment: If the Load Measuring System is faulty, use the Schindler 5500 LMS Guide to perform a zero-load calibration or re-calibrate using known weights.

TMMB (Traction Media Monitoring): Errors often stem from incorrect manufacturing dates for the steel belts. Enter the correct date into the system to clear persistent TMMB faults. Schindler Elevator Error Codes Guide | PDF | Electric Motor
