THE MOST COMMON COMBINATION OF DIFFERENT CONSTANTS
The machine will always run with the constants adjusted in the factory. But there are different conditions from farm
to farm and farmers also have different requirements. Therefore, some constants can be adjusted to the local
wishes.
1. Slow start of turbine. Machine data no.13. Adjust the value to 4sec to start.
Now the valve for control of speed will close about half and continue to close stepwise until the adjusted speed is
reached. Correct adjustment is: Continuously closing of the valve until the turbine starts running and stepwise until
adjusted speed is reached.
2. Slow opening for the inlet of water. Machine data No. 17 . Set the value to 1. =
The opening is done stepwise.
3. Only 1 motor for speed regulation. Machine data no. 12. Value 0
Post-irrigation must take place as follow: when the stop sensor is activated only the retraction stops. When the
post-irrigation is finished the machine starts again and runs to the mechanic stop.
4. Start of the 2
nd
machine when the 1
st
machine has reached stop.
Machine data No. 14. value 2.
The machine must be equipped with an adjustable pressure switch. Adjust the pressure switch to a point between
the normal pressure and the pressure when the pump will stop. Example: the normal pressure is 7 bar, the
pressure for pump stop 9 bar. Adjust the pressure switch to 8 bar on both machines. Start the 1
st
machine by
pressing start. Adjust the 2
nd
machine, but press stop. When the first machine is ready the second machine starts
as soon as its pressure has reached 8. Please note: 10 m of height difference make a pressure of 1 bar.
5. Stop of the machine when pressure is low and a pressure switch is mounted. Constant no.6 = value 1
Machine data No. 12 must be adjusted to a value of 2.
Now the shut-off motor turns into the opposite
direction. This means that when the cable connection stays the same the shut-off valve opens. After two minutes
the shut-off valve closes again.
Only the combination of stop sensor, stop button and supervision can open the shut-off valve. The pressure switch,
however, cannot open the valve.
6. Pre-irrigation before machine reaches the stop
Constant No. 9 can be
set to the meter number where the post-irrigation should take place.
Open the front plate very carefully.
In order to ensure moisture protection by the cover gasket also the cover
must be closed carefully!
Welding – and repair works at the RAINSTAR should only be done when
the battery is disconnected!
