Possible Causes
Limits set too close to physical end stops, Travel learning performed with obstruction present, Encoder miscount due to slipping drive, Control board parameter mismatch with door size
How to Fix / Troubleshooting
Safety: Ensure the door path is clear and the door is mechanically sound before recalibrating.
- Check physical stops: Verify that the door does not hit the floor or header too hard at the ends of travel.
- Reset limits: Use the BFT programming procedure to erase and re-learn the open and close positions. During learning, allow the door to travel fully without obstruction.
- Inspect drive connection: Ensure the drive sprocket, belt, or chain is tight and not slipping on the motor shaft.
- Adjust parameters: Confirm that door height and travel parameters in the control menu match the actual door.
