MM462 Installation Instructions 1
MIGHTY MULE MM462 GATE OPENER
_____________________________________
DRIVE
_____________________________________
• Low friction screw drive (linear actuator) rated for -5 °F to +160 °F (-20 °C to +71 °C).
• Powered by a 12 V motor with integral case hardened steel gear reducer. Motor speed reduced to 260 rpm.
• Maximum opening arc of 110°. Approximate opening time (90°): 18 seconds, depending on weight of gate.
_____________________________________
POWER
_____________________________________
• The system is powered by a 12 Vdc battery.
• Battery charge is maintained by a 120 Vac, 14 Vac output transformer (10 VA) through the GTO control board
or by optional GTO Solar Panels; the panel should generate minimum of 10 Watts. 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 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 dual leaf, pull-to-open gate installations. Jumper can be
removed to accommodate an optional kit for push-to-open gates.
• A circuit on the control board regulates charging. “Sleep draw” is 15 mA; “active draw” is 3 to 8 A.
• Auto-memorization of digital transmitter code.
• GTO RF receiver tuned to 318 MHz.
• Opener length with push-pull tube fully retracted is 26
3
/8", mounting point to mounting point. Maximum stroke is
13".
• Adjustable auto-close timer (OFF to 3–120 seconds), and Dual Sense Technology stall force.
• Power terminal block accommodates a transformer or solar panels.
• Accessory terminal block fully compatible with all Mighty Mule access controls.
• Control board allows connection of 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 could achieve prior to the 12 Volt 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 and 12 Volt battery. Actual cycles may vary slightly depending upon the type
and condition of gate and installation.
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 2)
* These specifications are subject
to change without notice.
