Sectional and rolling steel doors commonly use torsion springs to counterbalance the door’s weight. Over time, and with repeated use, the springs can relax and cause a door to become unbalanced. This imbalance may strain components, cause door drift and even lead to premature torsion spring failure.
PULSE operators (Series 100, 200 and 300) include a diagnostic feature to detect door imbalance. The Automatic Balance Check, accessible from the control panel menu, runs the door through a full cycle and displays the force required to open versus close the door.
A difference in these figures indicates the degree of imbalance. Adjusting the spring tension based on these results to get these numbers as close as possible will help restore proper balance without removing the operator or relying on guesswork. A balanced door will extend spring life and improve battery backup performance.
