Electrical/Control Systems

Optional High-Flow Module (Early Machines)

Early machines equipped with the optional highflow have an additional high-flow module (S, Fig. 544) installed underneath the multi-function control module (N). The high-flow module provides control logic for the optional high-flow auxiliary hydraulics circuit.

NOTE: Later machines have the optional highflow integrated into the “Multi-function Control/ Interlock Module (Controller 3)” on page301.

Control Module (Maestro Controller 2)

Control module (R, Fig. 538 and Fig. 543) provides:

•Logic for travel drive and main control valve

•Pump swash plate I/O sensors and solenoids

•Bucket function outputs

•Transmission, control valve and controller communication error codes broadcast output
