DRIVE
• Low friction screw drive (linear actuator) rated for -5 ºF to +160 ºF (-21 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 10 W at
600 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 dual 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 37

", mounting point to mounting point. Max stroke 19".
• 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 352 Au
