NOTE: LiftMaster gate operators have two obstruction sense adjustments (left and
right) where other gate operators have only one. This allows greater
flexibility of installation. For instance, you can install a gate on an incline
and not worry about sacrificing downhill gate sensitivity.

Adjustable pot controls gate sensitivity to blockages by the
instantaneous rise in motor current. When the limit is exceeded, the
gate stops and reverses a programmed distance (a minimum of 2
inches).
Adjustable pot controls gate sensitivity to blockages by the
instantaneous rise in motor current. When the limit is exceeded, the
gate stops and reverses a programmed distance (a minimum of 2
inches).
Adjustable pot controls the delay in sensitivity to gate
obstructions. This delay in sensitivity prevents the initial motor
inrush current from causing a obstruction fault. The weight of the
gate determines this setting.
