Which DG Motor Suits Your Garage Door?
Start with the garage door system, then consider door size, balance, condition and the drive capacity required. The highest torque rating is not automatically the correct choice for every door.
Sectional or roll-up?
Sectional doors use the 800Nm or 1200Nm style of operator. Roll-up doors require the dedicated roll-up motor.
How much drive capacity?
The DG 1200Nm has a higher published torque rating than the 800Nm model, but the complete door must still be assessed.
Battery backup
Battery-backup provision is listed for both sectional motors, while the roll-up operator is described as having true battery backup.
Safety accessories
Obstacle detection, photo beams and safety inputs should be considered according to the selected motor and installation.
DG Garage Door Motor Installation
Garage door automation should start with a mechanically sound door. Before fitting a motor, the door should move correctly by hand, be properly balanced and have safe springs, cables, rollers and tracks.
Installation can include inspection of the existing door, motor selection, fitting, travel-limit setup, safety checks and testing of the completed automated system.
What Should Be Checked?
- The garage door should operate smoothly by hand.
- Springs and cables should be in safe working condition.
- Tracks, rollers and hinges should not bind or be damaged.
- The door should be correctly balanced.
- The selected motor should suit the door system and application.
- Safety accessories should suit the installation requirements.
DG Garage Door Motor FAQs
What is the difference between the DG 800Nm and 1200Nm motors?
Both are sectional-door operators. The main published difference is the motor rating: 800Nm versus 1200Nm. The 1200Nm specifications also list an enclosed gearbox and photo-beam compatibility.
Can the DG sectional motors be used on roll-up garage doors?
The DG range includes a separate operator specifically for roll-up garage doors because roll-up doors use a different curtain-and-shaft mechanism.
Do DG garage door motors support battery backup?
Battery-backup provision is listed for the 800Nm and 1200Nm sectional operators, while the roll-up operator is described as having true battery backup.
Does a higher Nm rating automatically mean I need the 1200Nm?
No. The correct motor depends on the complete garage door system, including the door type, size, balance and operating condition.
Does the DG roll-up motor have obstruction sensing?
Yes. The supplied specifications list load-profiled obstruction sensing for the DG roll-up operator.
