Fitting Electrical Socket to Tractor

IMPORTANT: The electric power supply must be connected in accordance with the wiring diagram and as described in this section.

Verify, before connecting the sprayer, control box and GreenStar display, that the power supply is connected and functions as described.

Failure to follow these instructions can cause severe damage to the electrical system of the machine.

Always keep the battery well-charged (12 V minimum, 14.4 V maximum) and ensure proper functioning of the alternator.

Tractor Power Supply Requirements

Power supply socket (D) should be available in the tractor cab (3 pole, 12 Volt Cobo). The power supply has to switch the relay from the main power supply cable. Make sure the power supply works as shown in the drawing.

The relay (A) ensures voltage feed via the ignition to the main power supply cable. Once the vehicle is started, the relay (A) temporarily switches off the system in order to prevent voltage differences. This must be verified with a voltage tester, before fitting the plug into the socket.

If the described tractor power supply is not available, this has to be installed as follows. For relay (A) use part number WZ2605102.

  • Connect a +12V-wire (I) from the relay (A) to the +12V connection of starter motor of the tractor (starter relay).
  • Connect a +12V-wire (H) from the relay (A) to the +12V connection from the ignition of the tractor.
  • Connect the ground wire (F) to the negative pole (-) of the battery (C)
  • Connect a +12V-wire (E) with a 30 A fuse (B) to the positive pole (+) of the tractor battery (C)
  • Connect the a +12V-wire (G) from the relay (A).

Can-Bus Wiring Harness

After verifiying that the tractor power supply is operating correctly, the Can-Bus wiring harness has to be installed in the tractor cab as shown in the drawing. This wiring harness is pre-assembled as far as possible. After the wiring harness is installed in the tractor cab, the remaining cables have to be connected

to the tractor battery and the 9-pole ISO plug together with all separate plugs as follows:

  • Install the pre-assembled main relays (2) on the tractor
  • Connect the brown ground wires (6) to the negative pole (-) of the battery (3)

  • Connect the white +12V-wires with 60A fuse (4) and 30A fuse (5) to the positive pole (+) of the tractor battery (3)
  • Mount socket (35) on the back of the tractor and connect the cables as follows in the socket:
    • Brown (Br/ground /60A) to position 1
    • Brown (Br/ground/25A) to position 2
    • White (Wt/+12V/60A) to position 3
    • White (Wt/+12V/25A) to position 4
  • Connect 2-pole socket (28) from the Power harness (7) to 2-pole plug (27) from the T-splitter cable (26)
  • Connect 2-pole plug (34) to socket (35)
  • Connect 4-pole plug (33) to socket (35)
  • Mount 14-pole socket (9) in the tractor cab near the position where the command box (8) has to be installed later
  • Connect 2-pole socket (23) from the T-splitter (26) to 2-pole plug (22) from the System harness (19)
  • Connect 4-pole socket (25) from the T-splitter (26) to 4-pole plug (24) from the System harness (19)
  • Black/grey 10-pole plug (11) is used to connect the GreenStar display (10) later
  • Grey 10-pole plug (12) is not used
  • Terminator (16) indicates the end of this Can-Bus cable
  • 2-Pole plugs (21, 31 and 32) are not used as is the remaining brown wire and diagnostic connector (20) from the system harness
  • Connect 3-pole (Cobo) plug (17) to the 3-pole socket (18) in the tractor. See also "Tractor Power Supply Requirements" in this section.
  • Connect 4-pole socket (30) from power harness (7) to 4-pole plug (29) from T-Splitter (26).

Can-Bus Wiring Harness (preassembled box)

A kit with a preassembled box for quick and easy installation is available, to connect the sprayer with CAN bus to different tractors.

This kit contains the preassembled box and a power supply cable with 9-pole socket for connection to the battery of the tractor. Connect the power supply cable with socket to the battery first:

  • Mount the power socket with bracket at the rear of the tractor
  • Connect the red wire to the positive pole (+) of the battery
  • Connect the black wire to the negative pole (-) of the battery

The box (A) should be installed at the rear of the tractor. This box comprises the following connections:

  • 9-pole ISO-11783 CAN socket: The CAN bus cable with 9-pole plug coming from the sprayer should be connected to this socket.
  • Cable with 14-pole CAN bus socket: This cable should be connected to the cable with plug coming from the EHC-2 control box in the tractor cab
  • Cable with two 10-pole connectors (black and grey): The black connector should be plugged into the GreenStar display socket in the tractor cab. The grey connector is used for connection to the mobile processor (not yet available for sprayers)
  • Cable with 3-pole 12-Volt COBO plug: This connector needs to be plugged into the 3-pole COBO socket in the tractor (see also item "Tractor Power Supply Requirements" in this section).
  • Cable with 9-pole ISO-11783 connector (only used for power supply): This cable should be connected to the 9-pole power supply socket, previously installed at the rear of the tractor
