OBSTRUCTION SENSITIVITY SET UP
IMPORTANT: For safety reasons the obstruction setting or
stall force on the Polaris Automatic Gate Operator control
board comes from the factory set at minimum,(turned all
the way counter-clockwise). In many gate installations, this
setting will need to be adjusted to overcome the weight and
size of the gates.
The STALL FORCE potentiometer on the circuit board
controls the obstruction sensitivity (or the amount of
force the operator will apply to an obstruction) before
it automatically stops and reverses direction of the gate.
Adjust the sensitivity beginning at the factory default
counter-clockwise position. Continue to incrementally
increase the force until the gate can open and close
without obstructing under its own weight.
NOTE: The stall force may need to be increased in cold
weather due to increased resistance from gate hinges.
NOTE: The OBSTR LED will light to indicate an
obstruction is sensed.
