RIN

Depending on the crane configuration, RIN computers are
mounted in the universal boom top junction box, luffing jib top
junction box, or fixed jib top junction box
The junction boxes are interconnected in series with
electrical cords that run up the boom to the last attachment
component. The RIN computer in universal boom top
junction box receives inputs from load sensors, limit
switches, angle sensors, and other RIN computers in series.
The RIN computer in universal boom top junction box
transmits output information to crane EPIC computer in
operator's cab.

compared with the voltages shown on the LMI (Rated
Capacity Indicator/Limiter) diagnostic screen.
If the voltages do not match, the EPIC computer and the LMI
are not communicating properly.
