Description
The hydraulic system is operated through an elec-
trically-operated control valve that receives its sig-
nals from the hydraulic frame controller. The hy-
draulic frame controller contains the actual soft-
ware logic and therefore controls most of the out-
puts. It is located near the main control valve.
The hydraulic cab controller is placed in the side
console of the cabin and controls most of the input
signals. The two units communicate with each
other through CAN Bus, see Figure 1. The frame
controller determines what the accompanying out-
put must be.
