– model 04580), the at each front traction motor (SC5: Traction 1 and SC6:
Traction 2), in the optional rear traction motor (T5: Traction 3), in the steering
motor (SC7: Steering), in each lift/lower actuator (SC1: Lift/Lower 1, SC2:
Lift/Lower 2, SC3: Lift/Lower 3), in each cutting unit motor (T2: Cutting Unit
1, T2: Cutting Unit 2, T3: Cutting Unit 3), along with direction from the T1:
Primary controller via the CAN bus system. Since the T1: Primary controller (a
12 VDC component) sends and receives information with the starter/generator,
traction motors, and the remaining 48 VDC components, the CAN bus needs to
communicate with both systems. The CAN bus isolation module is included in the
system to allow communication between the different voltage controllers while
keeping the two electrical systems isolated. Also, the location ID module exists to
identify the location of the three cutting unit motors and the optional rear traction
motor. The ID module enables machine operation features such as starting and
stopping the center cutting unit slightly later than the front cutting units.
The 48 VDC system is an isolated system so the vehicle frame is not used for
any ground connections in this system. A 48V battery disconnect is located
behind the left side cover of the machine. Use the 48V battery disconnect
to make sure that 48 VDC components do not operate unexpectedly when
performing service procedures.
