ADVANCED ELECTRONIC MOTOR PROTECTION
The advanced motor controls of the S-80 are designed to protect both the motor and the PC
board in a stalled motor condition. This is achieved using the following procedure:
During gate arm movements, when maximum motor torque is applied and the expected
•
corresponding gate arm movement is not detected, the S-80 automatically reduces the
driving torque on the motor and returns to the previous position.
•
After a 10 second wait period, the S-80 attempts to drive the arm to the position
indicated by the Gate Control.
•
If the obstruction persists, the 10 second wait period is repeated for a second and third
time.
•
If the obstruction persists on the fourth attempt to move the gate arm, the wait period is
extended to one minute intervals, and attempts to move the gate arm to the position
indicated by the Gate Control will continue until the obstruction is removed.

BI-DIRECTIONAL LOCK BAR (US PATENT NUMBER 7,690,702)
The S-80 is equipped with a Bi-Directional Lock Bar used to lock the mechanism at any angle,
in either direction, for maintenance purposes.
DUE TO DRIVE TRAIN CHANGES IN THE S-80, THE S-80 LOCK BAR IS
LONGER THAN THE S-60 LOCK BAR AND DESIGNED TO HOLD
HIGHER DRIVE TRAIN TORQUE LEVELS.
DO NOT USE THE LOCK BAR PROVIDED WITH THE S-60 ON S-80
MECHANISMS.
The bar is placed over the Reaction Pin on the Motor Adapter Plate and the Hex portion of the
Motor Pinion Gear Shaft. Proper orientation of the bar is required to restrict upward or
