DRIVE
•
Low friction screw drive (linear actuator) rated for -30
o
F to +200
o
F. 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;
• 90º opening time: 15 s to 17 s, depending on weight of gate.
POWER
• The GTO/PRO 1000 system is powered by a 12 Vdc, 7.0 Ah, sealed, rechargeable battery
• Battery charge for GTO/PRO 1000 is maintained by a 120 Vac, 18 Vac (20 VA) transformer rectified to
14.5 Vdc through the GTO Control Board. Two (2) blade-style control board fuses are rated for 15 A.
NOTE: The transformer should not be connected directly to any battery. Do not replace fuses
higher ampere rated fuses; doing so will void the warranty and may damage the control board.
• Battery charge maintained by GTO Solar Panel Charger: float voltage 14.5 Vdc output from a

" silicon alloy panel. Generates minimum of 5 W at 300 mA. Gated diode on the control
board prevents battery discharge. NOTE: The solar charger should not be connected directly to any
battery.
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 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 71/2" to 111/2". Operator length
with push-pull tube fully retracted is 333/4", mounting point to mounting point.
• Adjustable auto-close timer (OFF to 120 s), inertia, and obstruction sensitivity using three (3)
potentiometers.
• Power terminal block accommodates a transformer and solar panels.
• DIP switches simplify setup of gate operator.
• 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 length of the gate and the number of operational cycles per day, the GTO/PRO 1000
can operate gates weighing up to 500 pounds, if all proper installation procedures have been followed.
Ball bearing hinges should be used on all gates weighing over 250 pounds.
These are the recommended guidelines when using the ac transformer (included) to trickle charge the
battery. See page 20 for information about maximum cycles provided by the GTO/PRO 1000 when using
the GTO Solar Panel.

NOTE: An operation cycle is one full opening and closing of the gate. The numbers shown in
this chart are for single gate applications, cycles for dual gate applications will be about
half of those with a single gate.
