Setup Options-ECU
Note: When ‘3 wire / Solenoid’ is selected this enables the sprayer to control 31 sections valves
and 1 ‘3 wire dump valve’, this is because both ‘3 wire Motor valves’ and ‘Solenoids’ only
require a ‘single’ signal wire to switch the valves ON or OFF. Therefore 31 sections can be
selected. The current looms only support 30 sections.
When ‘2 wire’ (2 wire Motorised Valves or Reverse Polarity Valves) is selected this enables the
sprayer to control 15 section valves and 1 ‘2 wire dump valve’, because ‘2 wire valves’ require
‘2’ signal wires to switch the section valves ON or OFF. Therefore only 15 sections can be
selected.

Select ‘3 wire / Solenoid’ if the sprayer is fitted with ‘3 Wire Motorised Section Valves’ or
‘Solenoid Section Valves’.
Select ‘2 wire’ if the sprayer is fitted with ‘2 Wire Motorised Section Valves’ (Reverse Polarity
Valves).
Select ‘2 Wire + power save’ if the sprayer is fitted with ‘2 Wire Motorised Section Valves’ and
the power saving feature is required. If the section valves does not receive a ‘signal’ from the
controller for 2 minutes the power to the section valves is switched OFF. This conserves power.
Note: The ‘2 Wire + power save’ feature is only supported on Spray ECU’s with firmware
version 209 or higher.
