Preparation, Fitting the SUPER-DRIVE Operator

Pic 3

An optional Beeper model 850 may be fitted to sound at the start of each door movement and provide audible feedback during programming and door position calibration.

PREPARATION

Ensure that the door is free to move by hand without any stiffness or misalignment of track sections, which may cause the roller wheels to jump over the track joints. If the door movement is stiff at any point, the roller wheels should be adjusted to allow the door to be moved by hand pressure without any significant force. Any misalignment of track sections should be corrected to ensure the door runs smoothly.

Ensure that the door is reasonably well balanced preferably with the counterbalance spring tension biased slightly open. (Pic 4)

Counterbalance springs will weaken over time and the balance can become biased closed. The Zap obstruction sensing system automatically adjusts to

changes in door balance over a period of time. However springs should be checked and adjusted on each service visit at least once per year or 1500 door cycles, whichever is the sooner.

FITTING THE SUPER-DRIVE

OPERATOR

The Super-Drive Jackshaft Operator kit includes an anti-torque arm, which prevents the operator rotating and which is bolted to the Super-Drive back plate using the motor cover back spacer provided and secured to a spare hole on the jackshaft bearing plate or onto the doorframe.

It is preferable to lightly screw the torque arm to the bearing plate hole or doorframe securing point before mounting the Motor Cover and Super-Drive. (Pic 5)

Now slide the Cover back onto the door shaft as shown in the picture. (Pic 6 overleaf)
