RCU CONTROLLER LIGHTS ___________________________________________
The RCU controller is a solid state device that monitors and controls reel and lift electrical functions. The RCU communi-
cates with the MCU via the CAN network.
Each input and output signal is displayed through lamps located on front face of the controller. An active circuit will turn
an input lamp on, an inactive circuit will turn a lamp off. Outputs are active when their lights are on.
