DRIVE
• Low friction screw drive (linear actuator) rated for -20 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 220 rpm. Generates
330 ft.. lb. of torque at 12 V.
• Maximum opening arc of 110º. Approximate opening time (90º): 15 to 17 s, depending on weight of gate.
POWER
• 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 to 14.5 Vdc (20 VA) through the GTO
control board. Two (2) blade-style control board fuses are 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.
• Battery charge is maintained by GTO Solar Panel Charger: float voltage of 14.5 Vdc output from a 19

silicon alloy panel. Generates 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.
• Limit controls are mechanical. Adjustable range of push-pull tube is 7

", mounting point to mounting point.
• Adjustable auto-close timer (OFF to 120 s), inertia, and obstruction sensitivity using three (3) potentiometers.
• Power terminal bock accommodates a transformer and solar panels.
• DIP switches simplify setup of gate opener.
• Accessory terminal block 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
• Depending upon the length of the gate leaves and the number of operational cycles

can open single gates weighing up to 350 lb.—if all installation procedures have been
properly followed.
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, please see the specifications listed
on page 20 or call (800) 543-1236 or (850) 575-4144 for more information.
* An operation cycle is one full opening and closing of the gate.
