21 OPTIONS
21.1 LOW PRESSURE SHUT-OFF
The supply pressure on the central unit is monitored by a pressure gauge. If the supply pressure is lower than the
minimum pressure set on the pressure gauge, the shut-off valve closes (option), and the Linestar shuts down.
CAUTION
When turning the switch to "DRY" position the machine runs without irrigating (dry run). This may be necessary
when moving the LINESTAR to a parking position because of natural rainfall.
21.2 ELECTRIC SHUT-OFF VALVE (CENTRAL UNIT)
An electric shut-off valve in the supply line of the central tower is closed automatically, if the LINESTAR shuts down
by malfunction.
21.3 END GUN
To increase the irrigated strip width or the system spraying range inside the swivelling area, an end gun can be
mounted at the end of the LINESTAR overhang. It may spray along the whole irrigation strip or only along parts of
it.
If the end gun is thought to operate in interval mode, an automatic "ON/OFF" control unit must be installed.
21.4 BOOSTER PUMP FOR END GUN
In most cases the end gun needs a higher pressure than the other nozzles of the LINESTAR.
An electric booster pump mounted on the end tower generates the necessary operating pressure for the end gun.
The booster pump is connected to the gun on the overhang by a pressure hose..

This will only happen under the condition the "WET-DRY" switch has been set to
"WET".
If it has been put to "DRY" position the pressure gauge is inoperable..
