Drive Belt Tension And Alignment - Nice HySecurity SlideSmart DC Series Installation And Programming Manual

DRIVE BELT TENSION AND ALIGNMENT

Proper drive belt tension is important for prolonging
the life of the drive belt and maintaining the
superior performance of the operator. To check
the drive belt tension, take the following steps:
1. Remove the SlideSmart cover and protection
plate.
2. Turn off the AC and DC power switch.
3. Check to make sure the pulley is aligned
horizontally.
4. With your finger, apply light outward pressure
to the drive belt. If it is properly tensioned, it
should only move about 1/16 to 1/8-inch (1.6
to 3.2cm). See Figure 81 and Figure 82.
5. To replace or re-tension the drive belt. Loosen
the four motor bracket nuts and move the
motor accordingly.
6. Retighten the motor bracket nuts.
7. Replace the protection plate and SlideSmart
cover.
8. Turn the AC and DC power switches ON. This
cycles power which allows the operator to
search for the target magnet and "relearn"
its limits.
9. If you don't cycle the power, the operator will
not "relearn" its limits to operate properly.
NOTICE
Be aware that the gate will cycle open and
close (close or open) as it relearns its limits.
See Resetting the OPEN and CLOSE Limits.
