Schindler 5500 Error Codes <COMPLETE>

Symptom: Elevator runs for 2-5 seconds, then jerks to a stop with a heavy thud. Controller shows OC.

Step-by-Step:

Schindler periodically releases firmware updates that change error code behavior. For example, older firmware (pre-2015) would throw E-4213 for any encoder glitch, while newer firmware distinguishes between E-4213-01 (wiring) and E-4213-02 (resolver disc slip). Always update your Service Tool database.

The Schindler 5500 typically uses a main control board (VCB or similar) that displays codes via:

When the elevator goes into fault mode, you’ll often see a code like E-23 or FF-41. These are your first clues.

To avoid frequent error codes:

This guide provides a breakdown of common error codes and troubleshooting procedures for the Schindler 5500 elevator system, which primarily utilizes the Miconic TX control platforms. Common Drive & Movement Faults

These codes typically appear in the fault log (accessible via the

service tool) and relate to the inverter (VF drive) and motor operation. 0004 - Invalid Movement

: The controller detected encoder activity (car drift) while the car was supposed to be idle. Often caused by brake issues or machine slippage. 0013 - OverSpeed

: The car exceeded its rated speed during a run. Check for mechanical imbalances or drive parameter errors. 0430 / 0431 - Brake Switch Mismatch

: Feedback from the brake switches (KB/KB1) does not match the commanded state. Switch 0431 is a fatal fault requiring manual reset. 0432 / 0433 - Contactor Feedback Error

: The auxiliary contacts of the main (SH) or brake (SB) contactors are not in the expected state. This is often caused by debris in the contactor or wiring faults. 0435 / 0439 - Overtemperature

: High temperature detected in the motor (0435) or drive inverter (0439). Ensure proper machine room ventilation and check for cooling fan failure. 0447 - Excess Encoder Deviation

: Discrepancy between calculated and actual car position. Potential causes include slipping belts or a loose motor encoder. 0450 - Releveling Failure

: The car overshot the floor or the leveling sensors (PHS) are faulty/dirty. Shaft & Safety Circuit Codes

These errors generally prevent the elevator from starting any trip. 01 - Safety Circuit Open schindler 5500 error codes

: A primary safety contact (such as an emergency stop or pit switch) is open. 02 - Door Safety Circuit Open during Travel

: The car gate or landing lock circuit was broken while the car was moving. 10 - Travel Too Long

: The elevator did not reach the target floor within the maximum allowed time (trip timeout). 11 - Position Lost

: The control system lost track of the car's location in the shaft. A synchronization run (to terminal floors) is typically required. 92 - Travel Control I/O Abnormal

: Detected abnormal status in the inspection panel circuit (REC/RH). This often requires a manual reset via the SMLCD Service Tool Load Measuring System (LMS) Errors Errors in the range 1105–1126

indicate issues with weight detection, which can cause the lift to refuse calls due to "overload" even when empty. 1105 / 1109 / 1110 / 1112 : LMS requires recalibration.

: Load weigh signal is missing. Check the wiring to the LMS sensors.

: Signal out of range. The sensors may be damaged or the car is physically jammed. Diagnostic & Troubleshooting Steps

Schindler 5500 elevators use a sophisticated diagnostic system that displays error codes on the SMLCD (Service Module Liquid Crystal Display) interface. These codes are typically four-digit numbers or specific status messages that indicate malfunctions ranging from door sensor issues to critical safety circuit failures. Common Schindler 5500 Error Codes & Interpretations

While many codes are shared across the Schindler Miconic and Smart series, the 5500 often encounters these specific diagnostic statuses:

Error 72 (Motor Controller Over Voltage): Indicates the DC link voltage is too high. Technicians are advised to check battery voltage with the charger off or cycle the machine power.

Error 98 (General Fault/Reset Required): A common status indicating a system lock. This can often be cleared by a "101 reset" at the controller or a soft reset via the car top inspection box.

ISK LED Failure: A critical safety circuit issue where the 110V safety chain is interrupted. Even if 110V is measured, a missing ISK signal prevents the elevator from moving.

LMS (Load Measuring System) Faults: Often related to frequency deviations in the load cells. Proper adjustment requires frequency readings of on the SMLCD.

SALSIS Errors: Related to the Absolute Positioning System. Issues here usually require a full power cycle of the main and battery supplies to recalibrate the car's position. Diagnostic Interface (SMLCD) Navigation

To view active or historical error logs on a Schindler 5500, technicians use the following menu path on the controller: Symptom: Elevator runs for 2-5 seconds, then jerks

Login: Enter the service code (standard default is often ABCD or 1234).

Navigate: Use the Up/Down buttons to reach Status > Error Log.

Analysis: The display will alternate between the Error Code and the Motor Control Status. Safety and Reset Procedures

Understanding Schindler 5500 error codes is essential for diagnosing issues within these high-performance elevator systems. These codes typically stem from the Schindler BIONIC (miconic)

control system, which monitors everything from door synchronization to electrical load. Common Critical Error Codes

While the full technical manual contains hundreds of specific diagnostics, the following are frequently encountered in the field: Error 0001 (Safety Circuit Open)

: A primary safety contact is open. This usually indicates an emergency stop was triggered or a physical safety switch (like the pit switch or car top stop) has been flipped. Error 0002 (Door Safety Circuit Open during Travel)

: The landing lock or car gate contact was broken while the elevator was moving. This is a high-priority safety fault that halts the car immediately to prevent injury. Error 0004 (Door Stopped Out of Door Zone)

: The car stopped outside the designated level where doors are permitted to open. This can be caused by a power dip or a mechanical obstruction in the hoistway. Error 4305 (Unintended Movement Trip)

: The system detected movement while the doors were open or when the car should have been stationary. This requires a manual reset via hoistway access for safety reasons. Error 0094 (IDC Sensor Level Detection)

: Often related to the leveling sensors not reaching the required condition for accurate positioning. Diagnostic Categories

The Schindler 5500 organizes faults into logical groups to help technicians pinpoint the subsystem at fault: Description Common Faults Safety Circuit Physical switches and interlocks. Gate contacts, pit switches, buffer switches. Communication Data transfer between the controller and the car/landings. COM_Busreconf, Bus Error. Drive & Motor Power electronics and speed monitoring. OverVoltCTW, Speed Ref Missing, Field Loss. Timing and position of car and landing doors. Error in normal door closing, ThermoDoor. Troubleshooting & Reset Procedures Identify the Status : Determine if the fault is (currently occurring) or (historical/intermittent). Basic Power Cycle

: For non-critical software glitches, switching the lift off and back on can sometimes clear "ghost" codes. Manual Resets

: Critical safety faults (like Error 4305) often cannot be cleared via the software menu and require specific physical sequences, such as using the Service Panel (SMLCD) inside the car or at the controller.

For detailed technical diagrams or specific part numbers related to these codes, you may want to consult a certified technician or refer to the official Schindler Technical Knowledge Center for a particular error code?

Schindler 5500 is a mid-to-high-rise elevator system that communicates its "health" through specific digital codes on its control interface. When something goes wrong, the elevator doesn’t just stop; it tells a story of mechanical or electrical struggle through these numbers. The Story of a Typical Day in Error Codes

Imagine a busy morning in a 20-storey office building. The Schindler 5500 is humming along until it encounters a series of common hurdles: The "Stubborn Door" (Error 0352/0353)

: A passenger holds the door too long or something is stuck in the track. The elevator reports a Door Position Recovery Failure Door Unavailable , refusing to move until the path is clear. The "Safety Snag" (Error 0011/0010)

: Suddenly, a safety circuit is interrupted—perhaps an emergency stop was nudged. The system triggers an

, essentially "freezing" the car in place to ensure passenger safety. The "Identity Crisis" (Error 0020) : After a power flicker, the car might report a PositionLost

. It no longer knows exactly where it is in the shaft. To fix this, a technician must initiate a "re-learn" trip, where the car travels the entire height of the building to re-map its floor magnets. The "Tired Motor" (Error 0028/0435) : During a heatwave or heavy use, the motor may report OverTempMotor

. The car will often complete its current trip but then rest at a floor until it cools down sufficiently to resume service safely. Common Schindler 5500 Reference Codes Typical Cause Invalid Movement

The car moved when it was supposed to be stopped (e.g., brake slip).

A main contactor failure—the "switch" that sends power to the motor is failing.

A brake switch error; the mechanical brakes and the computer's commands are out of sync. JHC Pressed

The emergency stop button inside the car or on top of it has been activated. Releveling Failure

The car overshot the floor or the leveling sensor is dirty/faulty. Belt Life Limit

The "traction media" (the belts/cables) have reached their calculated lifespan and must be replaced.
