Technical Specifications - Mighty Mule MM560 Installation Manual

• Low friction screw drive (linear actuator) rated for -5 ºF
to +160 ºF (-20 ºC to +71 ºC). Use of heater bands on arm
and control box will enhance performance in extreme cold
temperatures.
• Powered by a 12 V motor with integral case hardened steel
gear reducer. Motor speed reduced to 260 rpm. Generates
680 ft. lb. of torque at 12 V.
• Maximum opening arc of 110º. Approximate opening time
(90º): 20 seconds, depending on weight of gate.
• The system is powered by a 12 Vdc, 7.0 Ah, sealed,
rechargeable acid battery.
• Battery charge is maintained by a 120 Vac, 18 Vac output
transformer rectified. One 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.
• OPTIONAL: Battery charge is maintained by GTO Solar
Panel Charger Kit (5 Watt minimum).
NOTE: "NR" indicates this size
and weight combination is not
recommended for the
Mighty Mule 560.
NOTE: Ball bearing hinges
should be used on all gates
weighing over 250 lb.
To determine the number of cycles the gate opener will perform using solar panels (see page 23)

Mighty Mule 560 Gate Capacity /Cycle Chart
Estimated number of daily cycles, based on use with a transformer and one(1) 12 Volt battery.
* An operation cycle is one full opening and closing of the gate.
These specifications are subject to change without notice.
• The Mighty Mule 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).
• 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.
• Operator length with push-pull tube fully retracted is
40-1/4" mounting point to mounting point. Max stroke 20".
• Adjustable auto-close timer (3 to 120 s), and Dual Sense
Technology Stall Force.
• Power terminal block accommodates a transformer or solar
panels. NOTE: Do not use solar panel and transformer
at the same time.
• DIP switches simplify setup of gate operator.
• Accessory terminal block fully compatible with push
button controls, digital keypads, loops, etc.
• Control board allows connection of edge sensors and pho-
toelectric 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 could achieve prior to the battery depleting to a
state where the unit will not function. This chart reflects a
Mighty Mule Automatic Gate Opener when charging with
a transformer. Actual cycles may vary slightly depending
upon the type and condition of gate and installation.
