• Full service controller with eight inputs and LED indicators for loops, card reader,
radio, etc.
• Reversible arm direction for right or left handed operation.
• Instant Reverse Device (IRD) monitor senses obstructions during motion.
• Fail safe (auto open on AC power failure).
• Raise gate input memory will memorize multiple vehicles – ideal for bar code
scanners and AVI.
• Ability to STOP arm in close travel if tail-gating is sensed at close loop.
• Anti-tail gate alarm - fires K1 relay to trigger a warning device when tail-gating is
sensed.
• SAMS with “memory” - allows Mega Arm to open a slide/swing gate first then
raises arm.
• Dynamic motor braking to preserve arm positioning.
• Direct drive gear reducer eliminates many parts that might otherwise fail.
• State of the art MOSFET motor drive technology, NO contactors or relays.
• Soft start and stop in open and close travel motions.
• No limit switches to fail - uses magnetic (Hall Effect) sensors to monitor arm
position.
• Maximum Run Timer for motor with anti-tamper protection in closing direction.
• Each operator configurable as primary or second operator.
• LED diagnostics for easy troubleshooting.
• Adjustable Timer-To-Close with on/off selection.
• Transient voltage protection on all inputs.
• Wrench or Socket Set
• Phillips Head Screwdriver
• C Clamps

TOOLS NEEDED
During assembly, installation, and adjustment of the operator, the tools listed below may be needed.
This model is intended for use in vehicular gate applications.
• High torque 24 volt Permanent Magnet DC motor
• On 120 Vac installations, unswitched duplex outlet gives convenient supply
for 120 Vac accessories
• Built in battery run - inherent 24 Vdc backup power with regulated 24 Vdc
for accessories
• Capable of being powered from 120 or 230 Vac, or UL Listed Class 2 Solar
Power
• Break away mount design for the 12-15 foot x 3 inch tubular aluminum
barrier arm
• Heater option MUST be used if temperature is 30° or below. Heater option
available for 120 Vac operators ONLY. Refer to Accessories page.
• All rust proof aluminum construction with white powder coat baked on
enamel. Molded Polyethylene UV stabilized cover never needs wax or paint
(excludes towers).
