Embodiment Construction

[0104] FIG. 1 shows in simplified schematic form the design of the control electronics for an agricultural application comprising a tractor 1 or tractor machine, an implement 2 (e.g. a trailer), and a device for connecting the implement 2 to the tractor 1. The cable harness 3. The application has only a single supply network 4 , 5 with a ground connection 4 (or reference line) and a supply line 5 . The ground connection 4 is connected to the negative pole 6 of the battery 7 of the tractor 1 and the power supply line 5 is connected to the positive pole 8 of the battery 7 . The ground connection 4 is also connected to the housing of the retractor 1 via a functional ground connection 9 . The power supply network 4 , 5 supplies the tractor central electronic control unit 10 and the additional electronic control units 11 , 12 , 13 and the local control unit 14 on the tractor 1 .

[0105] The control units 10-14 are directly connected to the ground connection 4, wherein the housin...
