Following the circuit diagram layout, all electric circuits are shown in
individual circuit diagrams. Some explanations are given below to
illustrate the layout.
Numbering of circuit diagrams
-
The respective numbering can be found on the corresponding cover
sheet and in the footer.
-
Depending on the machine no., the components fitted and the
country specification, there may be several individual circuit
diagrams for a given function.
Potentials
- Main power supply (battery)
- Ignition switch power supply (switched)
- Relay-controlled power supply
- Earth
- Housing earth (external)
Connections
-
The description provided inside the circle (e.g. “H44”) defines the
connection.
-
Numbers next to the circle (e.g. “1b”) describe the continuation of
the cabling in accordance with the circuit diagram numbering which
can be taken from the cover sheet or from the footer.
Designations
-
Connectors (e.g. „X10”, pin 2– 1– 6– 5).
Each chapter lists the respective connectors and their pin
assignment in the individual connection tables.
-
Modules (e.g. “A23”)
The arrows identify the functional inputs and outputs according to
the assignment table provided in chapter ZE.
-

Description of function:
Main power supply Power supply from the tractor to the baler is via connector XV. On the
tractor, this prower supply should be protected by a fuse of 25 A max.
Potential + 15 This is switched by the main switch T 12 on the control box
(electronics +).
Potential K 90 / 87 Potential K 90/ 87 is a power plus protected against reverse polarity by
diode V10.
Overvoltage protection VDR1 becomes conducting when overvoltage occurs. This smooths the
voltage peaks in the electronics circuit (+15 / -32).
