Stall Force Potentiometer Setting
IMPORTANT: For safety reasons the obstruction set-
ting 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 direction 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 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 weath-
er due to increased resistance from gate hinges.
Setting Auto-Close Time
CLOSE TIME (auto close timer): Determines how
long the gate will remain open before it automati-
cally closes. The limits are OFF and
3 - 120 seconds. The factory setting is
OFF.
NOTE: Auto-Close timer is disabled
(gate will not automatically close) if gate
is not in the open limit.
ALWAYS KEEP SAFETY AT THE TOP OF YOUR LIST
WHEN ADJUSTING OR
SERVICING YOUR AUTOMATIC GATE OPENER!
