Obstruction Sensitivity; Installing The Receiver - Mighty Mule Silver-HD Dual 25th annivesary series Installation Manual

Obstruction Sensitivity Potentiometer
IMPORTANT: For safety reasons the
obstruction setting or Stall Force on the
GTO® gate opener 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 flat blade 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 weather due to
increased resistance from gate hinges.
ALWAYS KEEP

Installing the Receiver

Use the transmitter to check the range of the receiver before permanently mounting it.
Consider the following when mounting the receiver:
• Standard receiver cable length is 10 feet (receivers with a longer cable are available as special
• Run the cable through PVC conduit to protect it from damage.
• DO NOT run cable in conduit containing ac wiring.
• DO NOT mount receiver on a metal fence or post; doing so will decrease signal range.
• The receiver range can vary from 50 to 100 feet depending upon weather, topography, and
• DO NOT mount upside down.
• MOUNT so that you have line of sight between remote and antenna.
• MOUNT 3 feet away from AC voltage.
• MOUNT as high as possible for optimum range.
