MIGHTY MULE FM402 GATE OPENER

_____________________________________

DRIVE

_____________________________________

• Low friction screw drive (linear actuator) rated for -5 °F to +160 °F (-20 °C to +71 °C).

• Powered by a 12 V motor with integral case hardened steel gear reducer. Motor speed reduced to 260 rpm.

• Maximum opening arc of 110°. Approximate opening time (90°): 18 seconds, depending on weight of gate.

_____________________________________ POWER _____________________________________

• The system is powered by a 12 Vdc battery.

• Battery charge is maintained by a 120 Vac, 14 Vac output transformer (20 VA) through the GTO control board

or by optional GTO Solar Panels; the panel should generate minimum of 10 Watts. 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 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. Jumper can be

removed to accommodate an optional kit for push-to-open gates.

• A circuit on the control board regulates charging. “Sleep draw” is 15 mA; “active draw” is 3 to 8 A.

• Auto-memorization of digital transmitter code.

• GTO RF receiver tuned to 318 MHz.

• Opener length with push-pull tube fully retracted is 26

", mounting point to mounting point. Maximum stroke is

13".

• Adjustable auto-close timer (OFF to 3–120 seconds), and obstruction sensitivity (stall force).

• Power terminal block accommodates a transformer or solar panels.

• 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 Automatic

Gate Opener when powered with a transformer. Actual cycles may vary slightly depending upon the type and

condition of gate and installation.

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 2.
