Topcom X20 manual Single Line Install, Dual Line Install, Connecting to the Dump Valve

Installation of Spray ECU 30S KEE Sprayer Kits V1.98 21/06/06

Single Line Install

5.Connect the connectors marked Section X (‘X’ represents the section number) to the correct section valves. Section 1 connects to the section valve on the far left. Section 2 connects to the next section valve and so forth until all the section valves are connected to the Valve Harness.The section valve with the highest number will operate the boom section on the far right. If there are too many connectors for the section valves, then as a general rule use the connectors with the lowest numbers first.

6.Cable-tie the spare connectors to the Valve Harness.

Dual Line Install

7.Connect the connectors using the lowest numbers first that operate the primary spray line (Line A). Starting with Section 1 to operate the section on the FAR LEFT of the spray line, when facing forward finishing with the highest number section valve on Line A to operate the FAR RIGHT.

8.Connect the connectors to the section valves which are going to operate the secondary line (Line B). Starting the lowest number on the Line B to operate the FAR LEFT boom section, finishing with the highest number boom section on the Line B to operate the FAR RIGHT boom section.

Note: If the Valve Harness needs the connectors replaced to suit the valves connectors 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 this procedure.

Connecting to the Dump Valve

6.The dump valve (not supplied) must be located between the pump and the flow meter.

7.The dump valve is activated when all sections are switched OFF, or the Master Switch is switched OFF, therefore all the flow is diverted back to the tank.

8.Connect the ARAG connector, labeled Dump 1 to the dump valve.

Note: During setting up of the sprayer the wires in the ARAG connector may have to be swapped, if the dump valve is going in the wrong direction.

9.If the Dump Valve connector is on the Sprayer Harness, then an adaptor will be required to connect the 4-Pin Weather Pack to the Dump Valve. Connect the correct adaptor to the Dump Valve from the following adaptors:

a)A2266- if connecting to a 2-wire dump valve and 12v is applied to the dump valve when the Master switch is OFF.

b)A2267- if connecting to a solenoid valve, with 6mm spade terminals and 12v is applied to the dump valve when the Master switch is OFF.

c)A2268- if connecting to a 3-wire dump valve and 12v is applied to the dump valve when the Master is OFF.

d)A2269- if connecting to 3-wire dump valve and 12v is applied to the dump valve when the Master is ON.
