: When 1505 appears alongside 1501 and 1502, it typically indicates a systemic position-tracking failure rather than an isolated sensor problem. In such cases, begin by inspecting the entire position encoder circuit—wiring, connectors, and mounting—before proceeding to component replacement.
Open emergency stop, gate switch failure, or landing lock issues. Brake switch mismatch.
The encoder is not reporting expected position changes. Solution: Check for a loose motor encoder, failing belts, or incorrect parameter settings. B. Door System Errors schindler 5500 error codes work
1 — DOOR OBSTACLE. A lanky courier jammed a handtruck at the threshold; a toddler's shoe wedged under the sill. The cab hesitated, breathed, and reversed. The display blinked "E1" like an apology. The courier swore, the toddler giggled, the guardian sighed. The elevator waited until the obstacle left and the door closed smoothly, as if nothing had happened at all.
Random hall calls don't register, or the elevator skips scheduled floors. Common Codes: 1102 : CAN-bus communication failure to the car. : When 1505 appears alongside 1501 and 1502,
If the elevator is in a fault state, use these standard reset methods before deeper troubleshooting: Single Reset
This group deals with the elevator's movement and positioning. Common faults include invalid car position (1501), position jump (1502), and invalid floor position during trip (1505) . These often point to a faulty or misaligned car position encoder or issues with its wiring. Brake switch mismatch
Many errors are simply input failures. Check the Inputs screen on the controller to see if a safety switch (e.g., pit switch, top of car) is open.
: Many encoder and position errors trace to wiring or connector issues rather than failed components. Test circuits thoroughly before ordering replacement parts.
