X20 Sprayer Reference Manual
Introduction
The Spray Electronic Control Unit (ECU) is a new generation Spray
Controller, which is used in conjunction with the Topcon Precision
Agriculture X20 (or X15) console. The X20 console is the graphical
interface of the Spray ECU controller. The Spray ECU replaces the
Spray Rate Interface.
The Spray ECU can control up to 30 section valves (3 wire), and
allows Automatic Section Control (ASC) of the 30 section valves (the
X15 console can control up 15 sections under ASC). The Spray ECU
can control up to 2 liquid tanks directly. If the Spray ECU is used in
conjunction with a Multi-Drive Electronic Control (MDECU) unit, it
can control up to 3 liquid injection tanks.
The Spray ECU can handle Boom Sensing inputs, therefore it can be
connected to existing Remote switches. The Spray ECU also has a
new feature called Section Mapping, which allows one section switch
to control a number of section valves. Therefore the existing Topcon
Precision Agriculture Switchbox or remote switches (usually 6 or 8
switches) can control all 30 section valves, when they are controlled
manually. The X20 Sprayer software sets up the section mapping to
allow the six switches to control the 30 section valves. The ASC still
controls all 30 section valves individually.
The Spray ECU can control Regulator or Proportional type Control
Valves. The Spray ECU can control 3 Wire, 2 Wire (reverse polarity)
or Solenoid type Section Valves.

Testing Procedure
WARNING
Before commencing testing procedure
disconnect the existing tractor harness from the
existing controller.
You must complete one of two testing procedures, before upgrading
your software.
Make sure you choose the testing procedure that is applicable to your
product.
Testing Procedure For Installations With No
Existing Switchbox (switches on existing
controller)
On existing tractor harness, turn the ignition on 1.
4-2
Check each Section Drive Output pin for voltage (refer to 2.
manufacturer manual of existing tractor harness for pin
details)
Locate where voltage is supplied, to determine if it can be 3.
removed without limiting existing functionality
WARNING
If it is not possible to remove this voltage, then
you must install a Section Drive Output Protection
Adaptor (A2812 for 37-pin on Connector 1 and
A2813 for 16-pin on Connector 3).
www.topconpa.com
X20 Sprayer Reference Manual
WARNING
When no voltage is found, disconnect the vehicle’s battery 4.
before continuing with installation.
Testing Procedure for Installations With Existing
Switchbox (including Joystick Control):
Determine whether it is possible to disconnect the existing 1.
Switchbox without limiting existing functionality, eg: Boom,
Lift, Lower or Fold
WARNING
If it is not possible to remove the existing
Switchbox, without limiting functionality and
voltage is present, then you must install a Section
Drive Output Protection Adaptor (A2812 for 37-pin
on Connector 1 and A2813 for 16-pin on Connector
If it is possible to disconnect the existing Switchbox without 2.
limiting existing functionality disconnect the Switchbox
On existing tractor harness, turn the ignition on 3.
Check each Section Drive Output pin for voltage 4.
(refer to manufacturer manual of existing tractor
harness for pin details)
When no voltage is found, disconnect the vehicle’s 5.
battery before continuing with installation.

Most Flow Meters have a label on the meter body that shows the
Flow Meter Calibration Factor in pulses/volume. Eg: ‘645 ppl
(pulses per liter)’ or ‘2441 ppg (pulses per gallon)’. This means
the Flow Meter sends 645 pulses to the Spray ECU for every liter
(or 2441 pulses for every gallon) of liquid that passes through
the Flow Meter. This value is the Calibration Factor and will
be required to be entered into the Sprayer software setup (see
“Calibration Factor”, page 8-39).

Different Valve Types
There are three different valve types, which are:
• 2-Wire Valve—this refers to an electric section, dump or
Regulator Valve
The valve is driven by an electric motor that is able to rotate
in both directions. Two wires are connected to this type of
valve from the controller. To rotate the motor 12V is applied
to one of the wires whilst GND is applied to the other. When
opposite voltage is applied to the two wires the motor will
rotate in the opposite direction.
Common terms for this system are Reverse Polarity or
Bi-Directional.
• 3-Wire Valve—this refers to an electric section, dump or
Regulator Valve
The valve is driven by an electric motor that is able to
rotate in both directions. Unlike the 2-wire valve, the 3-wire
valve has in built changeover relays that change the motor
direction, depending on whether 12V or 0V is applied to the
signal wire.
Contsant 12V and GND are required in addition to the signal
wire.
• Solenoid Valve—this refers to electromagnetic coil type
valves.
Solenoid Valves usually consist of a coil, that when exposed
to voltage produces a magnetic field. The magnetic field
draws a needle against a spring away from its seat, to allow
liquid to flow.

Regulator Valve Settings
Figure 8-5. Regulator Valve Settings
The Regulating Valves and their settings are critical for the correct
operation of the Sprayer, particularly if Automatic Section Control
(ASC) is to be used.
To have good control when using ASC a faster Regulator Valve
may need to be installed. A 20 second KZCO Valve will be
sluggish and give poor control when using ASC and should
be updated to the 6 second ARAG Valve (grey band) or faster
Regulator Valve. 6 seconds represents the time for the Reg Valve to
go from fully closed to fully open.
When a Controller mode is selected then the Max On Time, PWM
Setting, Min On Time and Gain Setting settings are automatically
set. These settings can then be fine tuned manually.

• Micro-Trak—should be selected if a Micro-Trak Regulator
Valve is used for regulation. When Micro-Trak is selected
the settings are entered automatically into the Max On
Time, PWM Setting, Min On Time and Gain Setting
windows and are optimized for the Mictro-Trak Regulator
Valve
• DICKEY-john—should be selected if a DICKEYjohn Regulator Valve is used for regulation. When
DICEKY-john is selected the default settings are entered
automatically into the Max On Time, PWM Setting, Min
On Time and Gain Setting windows and are optimized for
the DICKEY-john Regulator Valve
• Raven—should be selected if the Sprayer has Raven Fast
Flow Regulator Valve fitted, unless a Topcon Pressure
Relief (495181) has been fitted to the Raven Fast Flow
Regulator Valve.
The Raven Fast Flow has a three way valve which acts as
both a regulator and dump valve. The valve will go from
fully closed to fully open in 1.5 seconds. The PWM Setting
must be left on full (100%) otherwise this will impair
the operation of the Dump Valve and Automatic Section
Control.
If Raven is selected you will have to enter the settings
from Table 8-2 (page 8-19) into the Max On Time, PWM
Setting, Min On Time and Gain Setting windows.

CAUTION
When using a Raven Regulator that operates as
a Dump Valve then you must select the Close
Valve When Flow Off option. Failure to do this
could dead end the system and cause damage to
pumps, hoses etc.
See "Service Bulletins", Chapter 7 if a positive
displacement (piston or diaphragm) pump and a
Raven Fast Flow Regulator Valve are fitted.
TPA recommends a Pressure Relief kit (495181)
to be fitted to the Sprayer. If the kit is fitted then
follow the settings recommended in the Service
Bulletin.

TIP
Reverse Valve Direction
All Regulator Valves have a two wire control system. Polarity is
reversed to change the direction of the regulator when in use.
Select Reverse Valve Direction if the valve is turning in the
wrong direction, ie: pressure is being increased when the
decrease button is selected on the Working screen.
Close Valve When Flow Off
Select this option if using a 3 way Regulator Valve, which also
operates as a Dump Valve, such as the Raven Fast Valve.
Also select this option if Anhydrous Gas is being used through
the regulator.
Sensitivity
The Sensitivity setting refers to the Flow Meter signal and may
need to be set to Reduced to stop ‘hunting’. This setting will also
make the response to rate changes sluggish.

TIP
It is recommended that Standard is selected.
