The Mighty Mule® E-Z Gate Opener features adjustable obstruction sensing. This safety feature makes the gate stop and reverse direction within 2 seconds when it comes in contact with an obstruction. MIN is the factory setting; meaning the gate will exert the minimum force on an obstruction before it stops and reverses direction.

The Mighty Mule® E-Z Gate Opener also has an adjustable auto-close feature. After the gate reaches the fully open position, it can be set to remain open up to 120 seconds before automatically closing. Pressing the transmitter button at any time after the gate opens fully will cause it to close immediately. OFF is the factory setting; meaning thegate will stay open until you press the transmitter (or keypad, etc.) again.

DRIVE
• Low friction screw drive (linear actuator) rated for -5 ºF to +160 ºF (-28 ºC to +71 ºC).
• Powered by a 12 V motor with integral case hardened steel gear reducer. Motor speed reduced to 260 rpm. Generates
520 inch lb. of torque at 12 V.
• Maximum opening arc of 110º. Approximate opening time (90º): 18 seconds, depending on weight of gate.

POWER
• The system is powered by a 12 Vdc automotive or marine battery.
• Battery charge is maintained by a 120 Vac, 18 Vac output transformer [rectified to 14.5 Vdc (40 VA) through the
GTO control board] or by optional GTO Solar Panels [the panel should generate minimum of 5 W at 300 mA]. A
diode on the control board prevents battery discharge.
IMPORTANT: Never use both transformer and solar panel - this will damage the battery and control board.
• One (1) blade-style control board fuse is rated for 15 A.
NOTE: The transformer should not be directly connected to any battery. Do not replace fuses
with higher ampere rated fuses; doing so will void your warranty and may damage your control board.

CONTROL
• GTO microprocessor-based control board is set for single leaf, pull-to-open gate installations. DIP switches can be
adjusted to accommodate an optional kit for push-to-open gates (see Accessory Catalog).
• Control board has temperature compensated circuits.
• A circuit on the control board regulates charging. "Sleep draw" is 25 mA; "active draw" is 2 to 5 A.
• Auto-memorization of digital transmitter code.
• GTO remote-mounted RF receiver tuned to 318 MHz.
• Opener length with push-pull tube fully retracted is 371/4", mounting point to mounting point.
• Adjustable auto-close timer (OFF to 120 s), and obstruction sensitivity.
• Power terminal bock accommodates a transformer or solar panels.
• DIP switches simplify setup of gate opener.
• Accessory terminal block fully compatible with all Mighty Mule access controls.
• Control board allows connection of safety edge sensors and photoelectric sensors.
• Audio entrapment alarm sounds if unit encounters an obstruction twice while opening or closing.

OPERATIONAL CAPACITY
• The Gate Capacity Chart shows approximate cycles, per day, you can expect from the Mighty Mule 350 Automatic
Gate Opener when powered with a transformer. Actual cycles may vary slightly depending upon the type and condition
of gate and installation.
