If a tank pressure sensor is fitted in the bottom of the tank, it is possible to read the actual tank volume accurately in the GreenStar 2 display. The tank pressure sensor is a very sensitive electronic component and must not be struck or cleaned with high pressure, as the sensor could be damaged.
Sprayers with automatic filling are fitted with an electric suction unit. Also see "Electric suction unit for sprayers with single pump" in the section entitled "Operation of the Machine".
To fill the tank automatically do the following:
1.
Connect the filling hose to the suction unit of the sprayer
2.
Set switch 9 of the EHC-2 control box to automatic filling (AUTO).
3.
Set the manual 3-way suction valve(s) to "External Suction".
4.
Set the pressure selection valve to "Pressure-Free Filling".
5.
Select "Job Settings" with softkey G (or button G on the GreenStar display control).
