Obstruction Sensitivity Potentiometer
ALWAYS KEEP SAFETY AT THE TOP OF YOUR LIST WHEN ADJUSTING OR
SERVICING YOUR AUTOMATIC GATE OPENER!
IMPORTANT: For safety reasons the obstruction
setting or Stall Force on the GTO/PRO control board
comes from the factory set at MIN (minimum). 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
control board operates like a volume
control on a radio. It controls the ob-
struction sensitivity (or the amount of
force the opener will apply to an ob-
struction) before it automatically stops
and reverses direction for approximately
two (2) seconds.
Use a small slotted screwdriver to turn
the arrow in the center of the potenti
-
ometer. Adjust the sensitivity from the
MINIMUM position where the gate
operates without obstructing from its
own weight or the wind conditions in
your area.
NOTE: You may need to increase the
stall force in cold weather due to increased
resistance from gate hinges.
