Obstruction Sensitivity Potentiometer Setting
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 Mighty Mule® 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 obstruction
sensitivity (or the amount of force the opener will apply to an
obstruction) before it automatically stops and reverses direc-
tion for approximately two (2) seconds.
Use a small slotted screwdriver to turn the arrow in the center
of the potentiometer. Adjust the sensitivity from the MINI-
MUM 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.
