1.2.2Installing the Sprayer Harness

1.The Sprayer Harness connects to the Tractor Harness at the back of the tractor or vehicle via the connector and continues across the sprayer's chassis to the valve set. Figure 5 shows the Sprayer Harness and Valve Harness Assembly.

2.Do not cut or splice the Sprayer Harness. Excess cable should be strapped away to avoid vibration and wear.The typical Sprayer Harness has 5 connectors, they are labeled as follows:

Ground Speed- connects to the Shaft/Speed Sensor Kit which is supplied as part of this kit.

Flow Meter 1- connects to a flow meter (not supplied).

Pressure Sensor 1- connects to the Pressure Sensor which is supplied as part of this kit.

REG Valve 1- connects to a regulator valve (not supplied).

Valve Harness- connects to the Valve Harness which is supplied as part of this kit.

Note: The Sprayer Harness may have other connectors, refer to the Sprayer Installation kit that came with your sprayer kit for more information. The Dump Valve connector may be located on the Sprayer Harness. If the Valve Harness has an ‘Arag Interface box’ incorporated into the Valve Harness, then the ‘Dump Valve’ connector will be located on the Valve Harness.

Figure 6 : 3-Pin Weather Pack Sensor

Troubleshooting Tip: For testing purposes on all 3-pin sensor connectors (Shaft/Speed Sensor

and Flow Meter) the voltage on each pin should be as follows: Pin A: +5 VDC Signal, Pin B:

Ground, Pin C: +12VDC Sensor Power. Refer to Figure 6 below:

Connecting to a Speed Sensor

This installation is used if connecting an A328 Shaft/Speed Sensor Kit (for ground speed) or A449 Radar Sensor Interface Harness (not supplied) to the Ground Speed connector on either the Tractor Harness or Sprayer Harness.

Connect to only one (1) of the Ground Speed connectors.

Select one of the following:

a)Installing the Shaft/Speed Sensor Kit to an un-driven wheel on either the Tractor Harness or Sprayer Harness;

b)Installing the Shaft/Speed Sensor Kit to the Tail Shaft of a vehicle on either the Tractor Harness or Sprayer Harness;

c)Use and existing radar speed sensor for ground speed.

Installation of the Shaft/Speed Sensor kit to an un-driven wheel for Ground Speed

1.The Shaft/Speed Sensor and Wheel Stud Magnets can be fitted to any un-driven ground wheel, for example: front wheel of tractor or wheel on trailing sprayer. The magnet activates the sensor as the wheel magnets sweep past. Refer to Figure 8.

Note: Use of a driven wheel for ground speed may be subject to "wheel slip" and may not always reflect true ground speed.
