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 in-
stallations 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 stall force from the MINIMUM position
where the gate operates without obstructing from its own weight or the
wind conditions in your area.
