INTRODUCTION »

FEATURES

• 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.

TOOLS NEEDED

During assembly, installation, and adjustment of the operator, the tools listed below may be needed.
• Wrench or Socket Set
• Phillips Head Screwdriver
• C Clamps
