GTO® Gate Opener
DRIVE
• Low friction screw drive (linear actuator) rated for -5 ºF
to +160 ºF (-20 ºC to +71 ºC). Use of heater bands on arm
and control box will enhance performance in extreme cold
temperatures.
• Powered by a 12 V motor with integral case hardened steel
gear reducer. Motor speed reduced to 260 rpm.
• Maximum opening arc of 110º. Approximate opening time
(90º): 20 seconds, depending on weight of gate.
POWER
• The system is powered by two 12 Vdc, 7.0 Ah, sealed,
rechargeable acid batteries.
• Battery charge is maintained by a 18 Vac output trans-
former through the GTO control board. 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.
• OPTIONAL: Battery charge is maintained by GTO Solar
Panel Charger kits (5 Watt minimum).
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).
• 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.
• Operator length with push-pull tube fully retracted is
40-1/4” mounting point to mounting point. Max stroke 22”.
• Adjustable auto-close timer (3 to 120 s), and obstruction
sensitivity.
• Power terminal block accommodates a transformer or solar
panels. NOTE: Do not use solar panel and transformer
at the same time.
• 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
• The Gate Capacity Chart shows approximate cycles, per
day, you can expect from the GTO Automatic Gate Opera-
tor when powered with a transformer. Actual cycles may
vary slightly depending upon the type and
condition of gate and installation.

NOTE: Gray area indicates this
size and weight combination is
not recommended for the Silver-
HD gate opener.
NOTE: Ball bearing hinges
should be used on all gates
weighing over 250 lb.
To determine the number of cycles the gate operator will perform using solar panels,
please see the specifications listed on page 22.
* An operation cycle is one full opening and closing of the gate.
These specifications are subject to change without notice.
