Schindler 5500 Error Codes Top
Critical | Likely Result: Safety gear activation, rescue required.
Schindler 5500 utilizes the (Schindler Machine LCD) for diagnostics, which displays error codes when the system detects a fault. These codes often relate to safety circuits, drive performance, and the STM (Suspension and Traction Media) belt system. Common Schindler 5500 Error Codes
: The system detects an invalid state transition, such as jumping from "locked" directly to "closed" without passing through intermediate checkpoints. This is usually caused by a communication mismatch between the main SCIC board and the SDIC board, or a loose power supply connection on the car top.
Given that a significant percentage of elevator entrapments are door-related, these codes are common top errors. A persistent Code 0301 (Front door lock not made) indicates the car is not allowed to move because the controller senses an open door. As the top error, it directs the technician to check the door lock contacts on the landing, not the motor drive. schindler 5500 error codes top
The motor attempted to open the doors, but resistance was detected. Check for debris or mechanical binding in the door operator. Drive and Motion Control Errors
Turn off main power, lock out, and perform a megohmmeter (megger) test on the motor windings to check for insulation breakdown.
Allow the primary elevator control operating system to complete its boot cycle. Critical | Likely Result: Safety gear activation, rescue
| Code | Meaning | Likely causes | Quick fixes | |------|---------|---------------|-------------| | E01 / Door Fault | Door motor or door operator abnormal | Obstruction, misaligned tracks, worn rollers, broken door motor/drive | Check for obstructions; inspect rollers and tracks; verify door motor power and wiring; adjust limit switches; replace worn parts | | E02 / Door Safety Edge | Safety edge triggered or faulty | Damaged safety edge, wiring short/open, contaminated sensors | Test edge continuity; clean/replace edge; inspect wiring and connectors | | E10 / Position Encoder | Positioning encoder error | Faulty encoder, loose connector, interference, defective drive | Check encoder cable and connector; replace encoder; inspect drive electronics | | E11 / Brake Fault | Brake not releasing or holding | Worn brake lining, incorrect air gap, brake coil failure | Measure air gap and adjust; test brake coil voltage; replace linings or coil as needed | | E20 / Motor Overload | Motor thermal or overcurrent trip | Overweight car, jammed guide, motor issue | Check load vs capacity; inspect for mechanical jam; measure motor current; verify VFD settings | | E21 / VFD/Drive Fault | Variable frequency drive alarm | Overvoltage/undervoltage, overheating, component failure | Check supply voltage; inspect drive cooling; review drive alarm codes and reset/replace drive | | E30 / Safety Circuit | Safety chain open (e.g., overspeed, safety gear) | Tripped safety relay, open interlock, speed governor | Inspect safety circuit wiring; reset relays; check governor and safety gear engagement | | E40 / Communication Error | Controller–CAR or fieldbus comms lost | Faulty cable, EMI, failed module, wrong baud/settings | Test and reseat comms cables; replace modules; check grounding; verify comms settings | | E50 / Sensor Input Fault | Weight/load or door sensor invalid | Load cell fault, loose connector, damaged sensor | Test sensor outputs; replace faulty sensor; check calibration | | E60 / Battery / UPS | Backup supply fault (if equipped) | Battery failure, charger fault | Test battery voltage and charger; replace battery | | E70 / Configuration Mismatch | Parameter or firmware mismatch | Wrong parameter set, incomplete firmware update | Reload correct parameter set; reflash firmware; restore backup configuration | | E90 / Emergency Stop | E-stop circuit active | Activated E-stop button, wiring fault | Inspect and reset E-stop; check wiring and contacts |
Confirm no passengers are inside the elevator before executing reset commands or moving the car via inspection control.
: The car failed to reach the target floor within the maximum allowed travel time. 0447 (Encoder Deviation) Common Schindler 5500 Error Codes : The system
Or alternatively:
| Error Code | Description | Possible Cause | |------------|-------------|----------------| | E1201 | Door open timeout | Defective door operator or obstruction | | E2105 | Drive overcurrent | Inverter issue, motor short, or mechanical jam | | E3102 | Safety chain open | Emergency stop, gate lock, or overspeed governor | | E4103 | CAN bus communication error | Loose wiring between car and controller | | E5110 | Position reference lost | Faulty encoder or tape reader | | E6001 | Brake pickup fault | Brake coil or contactor failure |
: Switch off the main power and battery supply for 5 seconds before restarting. Section 7 - Troubleshooting
