Problem:
The tubular drive does not switch to slow travel in order to install the third limit position.
Remedy:
Tubular drive overruns the limit position or stops short of the set limit position.
Remedy:
- Check electrical installation, remove external devices, delete limit positions and then reset limit positions.
- Repair electrical installation and re-program limit positions.
- Stops have broken off or one or several attachments are broken. Repair system; reset tubular drive, then re-program limit positions.
