| Code | Description | Common Cause / Notes | | :--- | :--- | :--- | | | Safety Circuit Open | Indicates a break in the safety string. Check door contacts, pit switches, car top stops, and machine room safety devices. | | 111 | Emergency Stop | The emergency stop button on the car top or in the car was pressed, or the safety chain was broken during operation. | | 120 | Door Open Time Limit | The doors have been open longer than the allowed time (Door Dwell). Often caused by a blocked photocell or a stuck door operator. | | 121 | Door Closing Fault | The system cannot close the doors. Check for obstructions, worn door guide shoes, or weak door operator motor torque. | | 122 | Door Opening Fault | The system cannot open the doors. Check the door operator, belts, or mechanical linkages. | | 130 | Leveling Error | The elevator stopped outside the leveling zone. Can be caused by brake issues, encoder drift, or a worn guide shoe rubbing the rail. | | 140 | Overload | The load weighing device detected a weight exceeding the rated capacity. The elevator will usually park with doors open and bypass calls. |
When the elevator displays status 98, it requires a to clear the fault from the system memory and restart the system.
Before fancy screens, we had blinking lights. On the inverter drive unit (inside the machine room):
Clean the sensor eyes on top of the cabin. Inspect the positioning tape/magnets for misalignment or damage. Perform a system synchronization/learn run. 4. Communication & System Logic Errors (7x / 8x Series) schindler 5500 error codes free
For the most recent or model-specific codes (e.g., 5500 XL, 5500 MRL), contact your regional Schindler support office with your exact unit serial number.
| Code | Description | Likely Cause | Action | |------|-------------|--------------|--------| | | Door open timeout | Door obstructed, worn belt, or faulty limit switch | Check door tracks, clean sensors, test limit switches | | 0102 | Door close timeout | Excessive friction, defective door motor encoder | Lubricate tracks, check door operator belt tension | | 0115 | Light curtain / safety edge triggered | Obstruction or faulty sensor | Clear physical obstruction; replace sensor if false triggers persist | | 0140 | Door motor overcurrent | Motor stalled or short circuit | Inspect motor windings, check for mechanical binding |
Loss of communication with a board on the LON network, often a hall button (HPB). STM (Belt) Fault Slack belt detected or belt life limit has been reached. Subsystem Fault Categories | Code | Description | Common Cause /
Main microprocessor lost communication with a peripheral board (e.g., BIO or IOEC board).
Indicates the load weighing system requires calibration.
: A pocket manual often left inside the documentation pouch of the controller cabinet. It contains the exhaustive matrix of all 4-digit codes specific to that elevator's software version. | | 120 | Door Open Time Limit
Check the car top inspection box to ensure the stop switch is not activated.
If you are responsible for maintaining a building with a Schindler 5500 elevator, you know the drill. The car stops. The display flashes a cryptic alphanumeric code. Panic sets in—not just from trapped passengers, but from the dread of an expensive service call for something that might be a simple reset.
: Auxiliary contactors (RH/RH1) fail to pick up when a trip sequence is initiated. The controller detects an open connection or an improperly scaled MAX_DOOR_ZONE configuration parameter.
