Soft Start & Slow Stop
The operator is designed to reduce abrupt movement at the beginning and end of the door's travel.

Designed for Sectional Garage Doors
The DG 800Nm is intended for sectional-door automation. It is not the DG motor intended for roll-up garage doors, which use a different curtain-and-shaft mechanism.
Door balance matters
A motor should not be expected to compensate for a badly balanced door, damaged springs or excessive mechanical resistance.
Inspect the hardware first
Rollers, hinges, tracks, cables and springs should be in safe working condition before automation is installed.
Check the application
The door type, size and condition should be assessed before deciding whether the 800Nm operator is the right choice.
Consider backup needs
A battery-backup facility is listed for the model and can be considered where backup operation is required.
