Hi all,
I'm trying to find a PDF of the installation/service manual for a (the operator/controller). I believe it's an older model – maybe the BST-300 or BST-400 series.
The door works intermittently, and I need to troubleshoot the control board (LED codes) and check the motor/encoder wiring. I've searched online but only found random sales pages, no actual manual PDF.
Or know a reliable link?
