This report outlines verified error codes and troubleshooting procedures for the Schindler 5500 elevator system, based on technical documentation and field service guides. Core System Error Codes

These codes typically appear on the SMLCD (Schindler Monitoring and LCD Display) and indicate critical safety or movement failures. 0004 - InvldMovement (Invalid Movement):

This fatal error occurs when the controller detects encoder activity while the car should be idle. It often points to brake slippage or machine issues. 0019 - Watchdog Reset:

Triggered when the system processor detects an internal problem and restarts automatically to clear the fault. 0033 - Start Up:

A status message indicating the system was reset, either manually by a user or following an earthquake mode reset. 0709 / 1680 - Communication/Safety Circuit:

Field reports indicate error 709 often precedes a more permanent 1680 breakdown. These are linked to broken safety circuit signals or loose wiring from the control board to the frequency converter. Drive and Inverter Faults (0400 Series)

The Schindler 5500 utilizes advanced drive systems where specific codes identify mechanical vs. electrical failures. 0430 / 0431 - Brake Switch Mismatch:

The brake switches do not match the commanded state. 0431 is a fatal version requiring a manual reset. 0435 - Motor Overtemperature:

The thermal sensor in the motor has tripped. This requires cooling the motor and checking for restricted airflow or shorted windings. 0446 - Drive Trip Start Failure:

The drive commanded a start, but no car movement was detected. Common causes include excess encoder position deviation or slipping belts. 0448 - Drive Inverter Failure: Internal hardware failure within the drive unit. Door System & Peripheral Errors

Door-related faults are among the most common and often require physical adjustment rather than board replacement. 0352 - Door Position Recovery Failure:

The system lost track of the door's physical position during a run. DLM (Door Lock Monitor) Fault:

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:

Indicates the brake contact is not switching properly. Technical guides note that KB switches are highly problematic on this control system and often require replacement. Verified Maintenance Procedures TMMB (Belt Monitoring) Fault Recovery:

A common issue where the system requires the steel belt manufacturing date to be re-entered. To clear, navigate to Main Menu > Parameter > STDM Install Data , enter the correct date, and activate CLR Disable in the commands menu. PEBO (Pulse Electric Brake Opening) Maintenance:

If the "PeboBat" error appears, it typically signifies the emergency brake batteries (usually 12V 7ah) in the hoistway are depleted and require replacement. LMS (Load Measurement) Calibration: If frequency readings on the SMLCD are outside of

, the LMS system must be re-zeroed or recalibrated using a known load. step-by-step walkthrough for resetting a specific code, such as the Drive Inverter Schindler 5500 error 709 - Elevator Forum

Understanding these codes is the first step in restoring normal operation. Below are verified error codes frequently encountered in the field: schindler 5500 error codes verified

0003 (NoKSE_STDSTL): The car is parked at a shaft end, but the KSE (Limit Switch) signal is detected without a corresponding distance encoder value. This often indicates a mismatch in shaft parameters.

0004 (InvldMovement): The controller detects movement that is considered invalid or unintended. This can happen if the car drifts due to brake issues or machine slippage.

0005 (SH_on_STDSTL): The SH contactor is energized while the elevator is at a standstill. This is typically caused by a faulty contactor or manual interference.

0008 (SB_Fault): Indicates a failure related to the SB contactor. This may be due to the contactor being energized during a standstill phase when it should be inactive.

0010 (FC_Fault): The inverter has stopped due to an emergency or internal drive problem. It may also be triggered by a disconnection in the safety loop during a travel stroke.

0013 (OverSpeed): The system has detected that the car is exceeding its rated speed, triggering a safety halt.

0020 (PositionLost): The elevator has lost its position reference in the shaft. This usually requires a new "learn run" or reset of the shaft image.

0028 (OverTempMotor): The motor has exceeded its safe operating temperature. This is often caused by excessive starts or a failure in the cooling system.

0094 (IDC Sensor Error): The IDC sensor cannot detect the level correctly. A common fix involves manually rotating the transfer belt one full turn before refitting it.

0447 (Excess Encoder Deviation): There is a significant difference between the commanded and actual encoder positions, which may indicate slipping belts or a loose motor encoder.

1105–1112 (LMS Errors): These codes relate to the Load Measuring System (LMS) and usually indicate that the device needs recalibration. Resetting the Schindler 5500 System

Many minor faults can be cleared by performing a verified reset procedure on the controller.

Single Reset: Press the reset button on the GCIOCF PCBA once and wait for the control system to reboot.

Double Reset: Press the reset button once, wait for the red LED to turn off, then press it a second time. This fully re-initializes the control system.

ACVF Reset: To reset the drive, switch off the JH (Main Switch), wait at least three seconds, and then switch it back on.

Manual Error Clearing: Some technicians use a "1011" code input on the service tool to attempt a manual reset of persistent errors. Critical Components to Check
