4.9.3 Multiple nozzle body
pneumatic
These multiple nozzle bodies are installed in the
form of dual or 4-fold versions.
In this case it is possible to switch the desired
nozzle from the terminal. You8 may even switch
on several nozzles at a time. The pneumatic
control valves are integrated in the nozzle car-
rier. If a pressure of more than 4 bar is applied
to the compressed air connection (4), the valve
will open and fluid can flow out. Without pressure
the valve is closed.

4.9.4 Border nozzles, electric
(option)
With a nozzle body division 1-0 and 1-1 with
border nozzle control a border nozzle 25 cm
further towards the outside (exactly at the bor-
der of the field) is activated electrically via the
terminal. With this version, the switch-over ball
valve must first be switched on the outside wing
of the folding boom.

The outermost nozzle is deactivated when the
border nozzle is activated.
With a nozzle body division 2-0, 2-1, 2-2, 4-0 and
4-2 the border nozzles are switched only via the
terminal. With this version, no more switch-over
ball valve on the folding boom exists since the
border nozzles on the outermost multiple noz-
zle body is also engaged. If a border nozzle is
switched on, the main nozzle of the outermost
nozzle body is automatically disabled.
