ADJUSTMENT GUIDES (continued)
Speed Settings (DC motors only)
Speed settings are pre-programmed at the factory for the maximum
speed. Speed settings should not need adjustment with this unit.
However, travel speed for the opener can be adjusted to a slower
speed in both the Open and Close directions, to minimize wear on
heavier sectional doors.
NOTE: One-piece doors are automatically set to the slowest speed
during Limits programming and cannot be adjusted.
There are 3-speed settings available for sectional doors. Please note
that speed may be affected by door weight and balance, along with
condition of door components and tracks.
