Topcon A2677 manual Dump Valve Mode

X20 Sprayer Reference Manual

•Select 2 wire + power save if the Sprayer is fitted with 2 wire Motorized Section Valves and the power saving feature is required. If the section valves do not receive a signal from the controller for 2 minutes the power to the section valves is switched OFF, this conserves power.

Please note: The 2 wire + power save feature is only supported on Spray ECUs with firmware version 209 or higher.

Dump Valve Mode

If 3 wire/Solenoid was selected from Section Valve Mode (page 8-12) then select:

•Not used—if no Dump Valve is fitted to the Sprayer

•2 wire—if fitting a 2 wire Dump Valve to the Sprayer

•3 wire—if fitting a 3 wire Dump Valve to the Sprayer.

If 2 wire or 2 wire + power save was selected from Section Valve Mode (page 8-12) then select Not used.

Please note: When 2 wire section valves are fitted to the Sprayer then only a 2 wire Dump Valve can be fitted to the Sprayer; a 3 wire Dump Valve is not an option.
