The controller receives conflicting signals (e.g., both "Door Open" and "Door Closed" switches active simultaneously). 3. Drive and Inverter Faults (F21 / F23 Series)
Measure the resistance of the braking resistors. Verify that the regenerative grid connection is stable. Error 008 / F008: Motor Overtemperature user wants a long, SEO-optimized article about Schindler
Persistent obstruction; misaligned interlocks; worn landing door pick-up rollers.
Overvoltage during regenerative braking or undervoltage due to building power fluctuations.
Always start by reading the full error description on the SMLCD, then follow the recommended cause‑and‑action steps. For most position‑related faults, a learn trip is the first line of defense. For brake monitor codes, measure the brake air gaps and replace brakes when necessary. And for errors that will not reset, check external safety devices such as buffer switches before performing a single, clean reset.
