Introduction
The Spray ECU is a new generation spray controller to used in conjunction with the NEW
X20 or ZYNX X15 consoles brought to you by KEE Technologies. The Console is the graphical
interface of the Spray ECU controller. The Spray ECU replaces the KEE Sprayrate 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 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 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 KEE
Switchbox or Remote switches (usually 6 or 8 switches) can control all 30 section valves
when they are controlled manually. The ZYNX sprayer software sets up the section mapping
automatically. 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.
