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
