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.
• 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 a18 Vac output transformer rectified to 14.5 Vdc (20 VA) through the GTO control
board. One (1) blade-style control board fuse 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 GTO Solar Panel Charger kit (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 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

", mounting point to mounting point. Max stroke 22".
• Adjustable auto-close timer and obstruction sensitivity.
• Power terminal bock 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 the 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: "NR" indicates this
size and weight combination
is not recommended for the
GTO® gate openers.
To determine the number of cycles the gate opener will perform using solar panels,
please see the specifications listed on page 21.
* An operation cycle is one full opening and closing of the gate.
