ADJUSTMENT GUIDES
Force Settings
Force settings are pre programmed at the factory and “learned”
during the Open/Close Limit settings steps (see pages 6-7). For normal
use, these settings should not need adjustment with this unit.
However, conditions possibly requiring adjustment are:
1. Doors with very stiff weather seals.
2. Doors that start down, STOP, and reverse before closing.
3. Doors that start up, but STOP before they completely open.
