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.
