10.4 RCU CONTROLLER LIGHTS _________________________________________________
The RCU controller is a solid state device that monitors and
controls reel and lift electrical functions. The RCU
communicates 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.
