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
680 ft. lb. of torque at 12 V.
• Maximum opening arc of 110º. Approximate opening time (90º): 20 seconds, depending on weight of gate.
POWER
• The system is powered by a 12 Vdc, 7.0 Ah, sealed, rechargeable lead acid battery.
• Battery charge is maintained by a 120 Vac input, 18 Vac output transformer rectified to 14.5 Vdc (40 VA) through the
GTO control board. One (1) blade-style control board fuse is rated for 25 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.
• Battery charge is maintained by a GTO Solar Panel Charger: float voltage of 14.5 Vdc output is from a 19 3 / 8 " x 8 1 / 2 "
silicon alloy panel. Generates a minimum of 5 W at 300 mA. A gated diode on the control board prevents battery
discharge.
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 40 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 40 1 /
4 ", mounting point to mounting point.
• Adjustable auto-close timer, and obstruction sensitivity.
• Power terminal block accommodates a transformer or solar panels.
• DIP switches simplify setup of gate opener.
• Accessory terminal block is fully compatible with push button controls, digital keypads, safety loops, etc.
• 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 500 Automatic
Gate Operator when powered with a transformer. Actual cycles may vary slightly depending upon the type and condi-
tion of gate and installation.

To determine the number of cycles the gate opener will perform using solar panels, please see the specifications
listed on page 19 or call (800) 543-1236 or (850) 575-4144 for more information.
* An operation cycle is one full opening and closing of the gate.
