Pressure Sensor installation and connection

1.Mount the Pressure Sensor (A092) either upright or horizontal and support the brass gauge saver. To properly measure Spray Line operating pressure the Pressure Sensor must be positioned between the flow meter and the section valves. The supplied Pressure Sensor is a 5 Bar (72 psi) pressure sensor.

2.Connect the Pressure Adaptor Harness (H1125) to the connector labeled Pressure Sensor 1 on the Sprayer Harness.

3.Undo the two (2) nuts on top of the Pressure Sensor.

4.Place the two ring terminals on the Pressure Adaptor Harness onto the terminals on the Pressure Sensor. It doesn't matter which way around the terminals are attached to the Pressure Sensor.

5.Once the ring terminals are placed on the Pressure Sensor terminals replace the two (2) nuts and tighten the nuts securely.

1.2.3Installing the Valve Harness

1.The Valve Harness continues from the connector on the Sprayer Harness and connects to the Section and Dump Valves on the Sprayer.

2.The Valve Harness normally contains connectors for the section valves; either they are; ‘3 Wire section valves’, ‘2 Wire Section Valves’ or ‘solenoid valves’. See below for an explanation of the different types of section valves..

Note: If the Valve Harness has an Arag Interface box incorporated into the harness, then

the Dump Valve plug will be on the Valve Harness.

5.The typical Valve Harness has the following connectors, they are labeled as follows: Dump 1- connects to the Dump Valve.

Section X- connects to the Section Valves. ‘X’ represents the section number.

Sprayer Harness- connects to the Sprayer Harness.

3.There are different Valve Harness depending on which type of section valves on fitted on the sprayer.

Note: If the Valve looms need to be re-terminated because the connectors are different to the section valves being connected to, then make sure the ‘Sprayer Harness’ is disconnected from the ‘Tractor Harness’. Otherwise damage to the Spray ECU will occur if the wires are shorted out during the installation.

4.Secure the Valve Harness away from moving, hot or sharp objects to avoid chaffing and wear, using the cable ties provided.

6.Connect the Valve Harness to the Sprayer Harness.
