1.2 Installation of Spray ECU 30S KEE Sprayer Kits

All KEE Sprayer kits come with their installation guide which is specific to each kit, please use the specific installation guide which come with your KEE Sprayer kit. This section is a general guide for an installation of all KEE Spray ECU 30S Sprayer kits.

This installation guide will take the installer through the following steps:

1.2.1Installing the Tractor Harness

1.2.2Installing the Sprayer Harness

1.2.3Installing the Valve Harness

1.2.1Installing the Tractor Harness

1.Connect the Tractor Harness to the 37-Pin connector marked CONNECTOR 1, on the Spray ECU. Figure 4 shows the in-cabin assembly showing Spray ECU, Power/Comms Harness, Switchbox and Tractor Harness.

2.Run the Tractor Harness from the Spray ECU to the drawbar or the back of the vehicle. Ensure that the Tractor Harness is tied away from moving, hot or sharp objects. Do not cut or splice the Tractor Harness, all excess cable should be strapped away to avoid vibration and wear.

3.If the Tractor Harness has ‘2’ 37 pin connectors, then connect the ‘37’ pin connector (male pins) marked ‘CONNECTOR 1’ to the plug marked ‘CONNECTOR 1’ on the Spray ECU. Then connect the ‘37’ pin connector (female pins) marked ‘CONNECTOR 2’ to the plug marked ‘CONNECTOR 2’ on the Spray ECU.

Note: As a general rule the ‘CONNECTOR 2’ plug is only required if:

a)The sprayer has more than 10 boom sections.

b)The sprayer has more than ‘2’ tanks.

c)The Spray ECU is connecting to external switches which control the boom sections (boom sensing); for example boom section switches on a ‘T Bar’ or ‘Joy Stick’ or other ‘third party’ section switches.

4.Normally ‘CONNECTOR 3’ (16 pin) is only required if the sprayer requires extra pressure inputs, tank level sensors and extra encoder inputs. See Wiring Connections table for the Spray ECU 30S (A2643) controller for wiring pin-outs;( See Section 21.7).

5.The Tractor Harness has a 3-pin Weather Pack connector labeled Ground Speed, either an A328 Shaft/Speed Sensor Kit or A449 Radar Sensor Interface Harness (not included in this kit) can be connected to this connector. Typically the Radar Sensor Interface Harness would be connected to the Tractor Harness Ground Speed connector. Only one (1) speed connector must be used at any one time. Refer to 1.2.2 for installing the Shaft/Speed Sensor Kit or Radar Sensor Interface Harness.
