Electrical System Operation

Reelmaster 5010- H machines use two (2) separate
electrical systems. Most machine functions operate on
a typical 12 VDC system. The second system exists to
operate the electric cutting reels and is a 48 VDC electri-
cal system. Basic information about the two systems is
included below.

12 VDC System Operation

Engine electrical components, machine operation
switches, hydraulic solenoid coils, the machine Toro
electronic controller (TEC) and the InfoCenter display
are all included in the 12 VDC system on Reelmaster
5010- H machines. A 12 volt battery at the rear of the
machine and the engine alternator provide system elec-
trical power. Circuit protection for the 12 VDC system in-
cludes two (2) fuse blocks, an inline TEC logic fuse and
several fusible links.
Electrical System
12 VDC system communication between the TEC con-
troller, InfoCenter display and the motor/generator is ac-
complished on a CAN- bus communication system. Two
(2) specially designed, twisted wires form the bus for this
network. The bus wires for the 12 VDC circuits are black/
white and red/white.
Information about electrical components in the 12 VDC
system is included in the Component Testing and Ser-
vice and Repairs sections of this chapter.
