MM272 Installation Instructions
Step 3
Press and HOLD the 1st opener JOG CLOSE button on
the control board and be prepared to RELEASE the button
when the gate reaches the desired closed position/limit. Use
the JOG OPEN and CLOSE buttons to "fine tune" the gate
position if necessary.
Step 4
With the gates in the desired closed positions PRESS and
HOLD the SET LIMIT button until the alarm and RED
Light come on. Then release the button.
NOTE: The opener must be extended more than 7 inches to
set limits.
Step 5
NOTE: When the control box cover is removed the receiver range is reduced to less than 5 feet.
Press the transmitter button once (within 5 feet of the control board) and allow the gates to fully open. The alarm will beep once when
both gates reach the OPEN LIMIT. This indicates the limits for both arms are programmed in memory.
Step 6
Press the transmitter button and allow the gates to fully close to verify that they stop at the desired positions. Repeat Steps 2-5 if
correction is needed.
NOTE: If the gate stops and reverses you may need to adjust the Stall Force (see below).

Setting Dual Sense Detection and Auto Close Timer
Do not use the Dual Sense Stall Force adjustment to compensate for a gate
that is sticking or binding. Excessive Stall Force may cause damage to the gate
operator or gate system or Injury or Death.
The Stall Force adjustment controls the amount of force the opener will apply
against an obstruction before it stops and reverses direction. The adjustment
on the control board operates like a volume control on a radio. It controls the
amount of force the opener will apply to an obstruction before it automatically
reverses direction.
The Stall Force adjustment is located on the control board. Turn the “STALL
FORCE” arrow in the center of the potentiometer with small flat head
screwdriver. Adjust the sensitivity to the point 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. However, the adjustment must remain as near to minimum as possible and when the weather
improves decrease the setting to the appropriate position.
Setting Auto-Close Time
The Auto-Close determines how long the gate will remain open before
it automatically closes. The factory setting is OFF. Use a small flat blade
screwdriver, you can adjust the settings to OFF, or from 3 to 120 seconds.
NOTE: Auto-Close timer is disabled (gate will not automatically close) if gate is
not at the fully open position.

CAUTION
For safety reasons the Dual Sense Stall Force setting on the Mighty Mule control board comes from the factory set to the 10 o'clock position. This
setting may need adjustment depending on the size and weight of the gate.
ALWAYS KEEP SAFETY AT THE TOP OF YOUR LIST WHEN ADJUSTING OR SERVICING YOUR GATE SYSTEM.
