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
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.
