How to reset the Anti-Two-Block (A2B) alarm on a Link-Belt RTC?
Reset A2B alarm by lowering the load block, clearing the obstruction, then pressing the reset button on the operator display panel.
The Anti-Two-Block system prevents the load block from contacting the boom head by monitoring the headache ball position through weight sensors and proximity switches. When the A2B alarm activates, it immediately stops hoist-up functions and sounds an audible alarm.
Remember: LCR - Lower, Clear, Reset (Lower load block, Clear obstruction, Reset button)
