START: The turbine can only start if the magnet activates the stop sensor (or
stop sensors), see Menu 3 for controlling the function of the stop sensor.
When the ,,START key is pressed the shut-off valve opens. Next the by-pass
valve closes (the turbine starts). If the magnet does not activate the stop
sensor only the shut-off valve opens. This is used if the pressure should be
released before disconnecting the hose at the hydrant.
DELAYED START TIME OF IRRIGATION: First press ,,STOP”-key for closing the
inlet of water. Next press ,,MENU”-key 3 times (Menu 4), ,,PROG”-key 3 times
and you can start time. Finally, pre- and post- irrigation can be selected.
STOP: When the magnet is removed from the stop sensor, the turbine stops and
the shut-off valve over-pressure closes (or if available the shut-off valve
low-pressure opens). If post-irrigation is chosen, the turbine stops and after
the post-irrigation time the shut-off valve closes. If the key ,,STOP” is
pressed, the turbine stops and the shut-off valve closes, regardless if post-
irrigation was selected.
SUPERVISON: The ECOSTAR 4300 has an integrated supervison system. SUPERVISON
is activated if for some reason the machine irrigates at the same place longer
than a specified time. This time is factory adjusted to 20 minutes, see
programming for changing this time. If it set to 0 there is no supervison.

SPEED : The speed is set with keys ,,+” and ,, ­”, at first the speed changes
step by step 0,1 m/h, after 10 steps for 1,0 m/h. The speed can be changed at
any time, even while the machine is running. If the time is checked it shows
the new time for the remaining irrigation.
Manual for BAUER RAINSTAR series E11­E51XL
27
PRE-IRRIGATION: Pressing the key PRE- can activate pre-irrigation. The time
for pre-irrigation is calculated by the ECOSTAR 4300 as 8 x the time for
running 1 meter with the current speed. The constant ,,8″ (constant no. 2) can
be changed, see programming. If the pre-irrigation is on the machine starts
and runs 1/2 pm enter and then it stops for the pre-irrigation time. By
pressing the key ,,START” the pre-irrigation is cancelled. The magnet at the
stop sensor should be in place, before activating the pre-irrigation.

POST-IRRIGATION: The post-irrigation can be activated by pressing the key
,,POST-“. The time for post-irrigation is calculated by the ECOSTAR 4300 as 8
x the time for running 1 meter the current speed. The constant ,,8″ (constant
no.3) can be changed, see programming. The post-irrigation starts to count
down when the magnet is removed from the stop sensor. When the magnet is
removed, the motor for speed regulation stops the turbine. After the post-
irrigation time the shut-off valve closes ( or opens, is available, the valve
low pressure) At machines with only one motor for speed regulation the turbine
starts after the post-irrigation. By pressing the key ,,START” the post
irrigation is cancelled. The magnet at the stop sensor should be in place
before activating the post-irrigation. If the constant no.8 “early stop” is
selected, this function is activated. The machine shuts down if the distance
is reached.

PROGRAMMING OF 4 DIFFERENT SPEEDS

Display must show menu 5. The pipe should be pulled out before programming, so
the computer can calculate the distance of the field to be irrigated. In the
following example the length of the field to be irrigated is 400 m. Press the
,,PROG”-Key 3 x. The display shows. 400m 30.0m/h 0m

0m 30.0m/h 0m 0m 30.0m/h 0m 0m 30.0m/h 0m

The desired speed can now be set, here 25,0 m/h. Then press the ,,PROG”-key 1

6.3 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 2nd machine when the 1st 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 1st machine by pressing start. Adjust the 2nd 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.
ATTENTION!
Open the front plate very carefully. In order to ensure moisture protection by
the cover gasket also the cover must be closed carefully!
ATTENTION!
Welding ­ and repair works at the RAINSTAR should only be done when the
battery is disconnected!

6.4 STOP – SENSOR
The machine can only work if the stop sensor is activated or in operating
position.
Operating position
Shut-off position
The Stop – Sensor has three functions:




Reset for the laid-down PE-pipe length:
When operated the laid-down pipe length is set to zero.
2. Post irrigation:
If the post-irrigation procedure is carried out at the end of the run (0 m
laid-down PE-pipe length) the post-
irrigation function is activated first and then the ECOSTAR is shut-off.
In the standard program the post-irrigation is activated 8m before the
irrigation ends.
3. Prevents pulses to the regulating motor.
After the stop sensor is activated, no pulses are passed on to the regulating
motor.
Press the key MENU 2 x, to get to the display of menu 3. Her it shows if the
speed sensors are working . The sign
shows if a magnet activated the two speed sensors.

6.5.1 SPEED ADJUSTMENT

The pre-adjusted speed of 30 m/h can be increases or decreased with the arrow
keys
.
At first the speed changes step by step for 0,1 m/h, then after ten steps
there is a change of 1,0 m/h. The speed can be changed at anytime while the
machine is running. The remaining time until the end of irrigation is also
changed. The speed cannot be changed while one of the servo motor for the
turbine regulation or shut-off valve is running. The display shows MOTOR 1 or
MOTOR 2. When changing the speed also the corresponding time changes.

Important!
When setting the speed it is necessary to check on the speed that is actually
possible according to the test window (press menu key 3 x). In case of
variation the set speed must be reduced to the speed that is actually

possible.
6.5.2 PRE ­ OR POST IRRIGATION
With the keys PRE ­ or. POST IRRIGATION
these functions can be activated.
The time for the pre- and post is pre-programmed and is calculated by the
ECOSTAR 4300 as 8 times the time for covering a distance of 1 meter with the
actual speed.

e.g: for vE = 20 m/h there is a time of 3 min for 1 m retraction This makes a
pre-irrigation time of 8 x 3 min = 24 min and a post irrigation time of also 8
x 3 min = 24 min
This value “8” can be changed in the program (program constant No 2 and No 3)
­ See parameter sheet 1: constants. If the pre irrigation function is
activated, the machine runs approx. ½ meter after the start and then stands
still for the pre irrigation time.
Manual for BAUER RAINSTAR series E11­E51XL
33
When pressing the button “START-RESET”
, during pre-irrigation the pre-irrigation function is deleted.
Before activating the pre-irrigation mode the PE ­ pipe should be pulled off
(the shut-off frame and thus also the shut-off sensor should be in the
operating status) and the “START-RESET” key should have been pressed. If the
post-irrigation mode is activated the machine stops 8m before the end of the
run for the post-irrigation time. This value is pre-adjusted and can be
changed in the program constant no.9, see parameter sheet 1: constants.
If you press the key “START-RESET”
, the post irrigation is cancelled.
6.5.3 START

If the PE ­ pipe has been pulled off and the desired speed has been set you
can start the irrigation with the
“START­RESET”
key.
If pre- or post- irrigation is required, press the following keys

The turbine can only start if the shut-off frame and thus also the shut-off
sensor are in the operating state (PE-pipe pulled off). If the ,,START­RESET”
key is pressed the turbine flap closes, the tooth segment on the regulating
motor rotates to the limiting bolt head and the shut-off valve (if existing-
optional) opens.
Manual for BAUER RAINSTAR Series E11­E51XL
34
6.5.4 MONITORING

The program has a built-in monitoring system. It only works in connection with
the shut-off valve- overpressure.

The standard factory setting of the monitoring is 20min. (parameter sheet 1,
machine data 4). In this mode monitoring will start if the RAINSTAR does not
reach the set speed within the programmed monitoring time. After this time the
shut-off valve is closed and the machine stops. In most cases the reasons are
excessively high retraction speeds or a blocked regulation flap etc.

In order to ensure that the set retraction speed is actually reached and the
system is not switched off after the monitoring time, it is necessary to check
the retraction speed that is actually possible by pressing the menu key three
times.

If the system is equipped with a pressure switch the machine will start when a
preset minimum pressure is reached, or it stops irrigating when water pressure
is too low. As soon as the pressure returns to normal level, irrigation is
continued.

6.5.5 STOP

At the end of the irrigation run the shut-off sensor is activated through
shut-off frame and shut-off rods.

Sensor in shut-off position
As a result the turbine stops and the shut-off valve overpressure closes
slowly and remains in this position until the next operation.

If the RAINSTAR is connected to a hydrant you can release the water pressure
which is remaining in the line after
closing the hydrant by pushing the ,,START-RESET”
key.
The shut-off valve opens and pressure is released through the PE-pipe. If a
low-pressure shut-off valve is mounted, it opens quickly. It closes again
after approx. 15 min.
By pressing the key ,,STOP”
the irrigation process can be stopped at any time.
The turbine flap opens (the turbine stops), the over-pressure shut-off valve
closes, the low-pressure shut-off valve opens. The laid down PE ­ pipe length
remains saved. It is set to 000 only when the shut-off sensor is actuated (
shut-off position).
ATTENTION ! If the ,,STOP” key is used while retraction on a machine without
shut-off valve the retraction stops but the sprinkler is still in operation.
In order to prevent “over irrigation” around the sprinkler the machine should
only work for a limited period of time without retraction. Then start the
machine again by pressing the,,START” key!!
Manual for BAUER RAINSTAR series E11­E51XL
35
ATTENTION !

With machine data adjustments Pos. 12, adjustment ,,0″, the retraction stops
only for a short period of time when pressing ,,STOP” key. After a few seconds
the retraction starts again automatically. ATTENTION: when working on the
machine the whole drive needs to be switched off!!
STOPPING THE CONTROL FUNCTIONS,

By pressing the keys ,,STOP” and ,,PROG.” at the same time all functions of
the ECOSTAR stop, this means that the regulating motors of the turbine and the
shut-off valve remain in their current position. With this combination of keys
the turbine regulation is stopped when the turbine rotation speed is low in
order to change gears.

6.6 PRESSURE SWITCH ( OPTIONAL EQUIPMENT)
If the RAINSTAR, after having been positioned for the run, is supposed to
start-up only after the required pressure has built up in the supply line
(Pressure start) a pressure switch must be installed.

If such a switch is available, the monitoring system will also interrupt the
irrigation cycle in case of low water pressure. As soon as the pressure
returns to normal the irrigation is continued.
IMPORTANT:
the pressure switch should only be used together with a shut-off valve over
pressure!!

6.9 BATTERY
In the factory a battery of 12 V and 6,5 ampere hours is mounted.

Charging the battery with a standard solar panel during the irrigation season
is not necessary. Basically, the battery should be charged all 6 month with a
charging current of max. 2 ampere. (Please note the maintenance and operating
manual).
If the battery is connected the display shows for a short time e.g. “VERSION
4.1″, and then goes over to standard display again.
In order to ensure a long lifespan of the dry battery of the ECOSTAR (LC-R
127R2PG 7,2 Ah/20 HR), it is important to follow certain guidelines when
storing and charging the device. During operation of the battery on the
ECOSTAR no special precautions need to be taken as the solar panel permanently
charges the battery. 1. Every new RAINSTAR irrigation machine delivered by
BAUER, which is equipped with an ECOSTAR is also

equipped with a fully charged and ready to use battery. The solar
panel,however, is covered and not connected to the battery. If there is a
longer period of time between delivery and first operation the battery needs
to be maintained. (see following points) The same applies for spare part
batteries and batteries which were held on stock for a longer period of time.
2. If the RAINSTAR is not in operation for a longer period of time, e.g off
season, the battery should be disconnected from the ECOSTAR and dismounted. 3.
The accumulator battery should be stored fully charged, separate of conductive
materials and out of the sun. If the accumulator battery is stored in an
uncharged condition for a longer period of time the full capacity cannot be
reached again after charging. 4. The optimum storage temperature lies between
0° and +25°. Also during storage the battery underlies self-discharge and
needs to be charged in the following intervals:
Storage temperature: Less than +20°C +20°C to +30°C +30°C to +40°C
Interval for charging: 9 month 6 month 3 month
5. The humidity in the storage room needs to be low (55%+/- 30%) in order to
prevent that the poles corrode. 6. A complete discharge of the battery should
be prevented (deep discharge). The battery can be charged and

reach its full capacity again but a repeated deep discharge the lifespan of
the battery is reduced. 7. The accumulator batteries should be kept clean. For
cleaning a dry cloth can be used, if required soaked in

water or alcohol. Under no circumstances use oil, petrol or diluents.

8. Accumulator batteries must not be disassembled as they contain acid which
can cause strong chemical burns. 9. Accumulator batteries must not be hot-
wired as they could be damaged. 10. Charging the battery should be done with a
voltage of max. 2,0 A. If the battery is fully discharged the battery

needs approx. 7 hours until is is fully charged. Devices which check the
capacity of the battery, as well as devices with an intelligent (self-
regulating) charging function, enable an exact analysis as well as a
controlled charging of the battery.

6.9.1 SOLAR PANEL

In the factory a solar panel is mounted which is maintenance free. 1. In order
to ensure optimal performance the surface should be cleaned from time to time
with a soft cloth and

household cleaning agent ( no scrubbing agent). 2. For operation the solar
panel is unfolded and blocked. The solar radiation on the panel is more
intensive.

For transport of the RAINSTAR the panel is folded again. It is lifted and
pressed to the machine and can be brought into its initial position where it
is protected against damage.

3. In order to prevent over charging of the accumulator battery and a
disturbance of the ECOSTAR, the electronic interrupts the charging process if
the ,,STOP” key is pressed or the accumulator battery is connected (When the
machine is delivered the clamps are removed)

6.9.2 CHECKING THE CONNECTIONS

Press ,,START” key.

The regulating motor closes(the segment turns to the limiting bolt) The shut-
off valve overpressure opens. The shut-off valve low pressure remains closed.

Press ,,STOP” key

The regulating motor opens the turbine (the segment turns away from the
limiting bolt) The shut-off valve overpressure closes The shut-off valve low
pressure opens

6.9.3 CHECKING THE LENGTH SENSOR

The magnet disc with 4 magnets is mounted on the drive shaft of the gear and
rotates clockwise during retraction. By rotating the magnet disc clockwise the
display for the laid down pipe needs to count from 0 m upwards. If the
distance counter counts into the opposite direction then the speed sensor must
be turned around in order that the cable connection is on top. Distance 1 – 3
mm between double sensor and magnet disc.

6.9.4 LIMIT STOP FOR TURBINES ­ REGULATING VALVE WITH ECOSTAR 4300

See point 6.5. The regulating area of the regulating valve of the turbine
needs to be adjusted to the respective delivery rate. If the limit stop is not
adjusted correctly it might happen that the turbine cannot be regulated, this
means that the PE-pipe retraction happens with maximum speed.

If the flow rate is reduced significantly the limiting bolt head needs to be
adjusted again, as otherwise the retraction speed listed on the performance
chart cannot be reached.

You can see the required delivery rate on the performance chart fixed on the
machine below the nozzle sizes.

6.9.5 SHORT CHECKLIST FOR ECOSTAR 4300

1. Check battery voltage (should be 12 V minimum) a) Cover solar panel
completely b) See battery voltage In test menu 1 (press MENU key once) c) If
there is no or not enough power available (below 12 V), check battery, cable
connections or fuses inside the electronic box.

2. Check function of the sensors a) Set test menu 2 (press MENU key twice) b)
The display show indications for function control of the installed sensors ,
Motor 1 -Motor 2

3. Check length indicator of the laid down PE-pipe (press MENU key once ) a)
Read out the pipe length of the laid down PE-pipe on the standard display and
compare with the engraved length indication on the PE-pipe. b) If it shows 000
m, or significpless than the length of the laid out pipe, you need to make
settings.

4. Check of the mechanic transmission to the stop sensor.

5. Adjustment of the limiting bolt for the tooth segment of the regulating

8.1.1 CHECKLIST FOR ECOSTAR 4300

During the first run at the start of the season, but also during normal
operation, there can occur problems with the ECOSTAR, like negative reports,
malfunction in connection with the electronics or the connected sensors, as
well as problems due to operating errors. A systematic check of the system
according to the checklist below can help to identify and solve the problem
quickly. This checklist serves as an additional help to the detailed operating
manual of the ECOSTAR 4300. After checking the device according to the SHORT-
CHECKLIST, handling instructions are in the list below.

8.1.2 TABLE FOR PRE-AND POST-IRRIGATION

In order to correct irregularities at the beginning or at the end of the
irrigation strip the ECOSTAR has the function pre- and post-irrigation. The
precipitation height at the beginning of the strip (pre-irrigation) and at the
end of the strip(post-irrigation) is reached by short interruptions of the
cart retraction. The downtime for the preand post-irrigation is adjusted at
the ECOSTAR with the program constant 2 and 3 on the parameter sheet no.1. The
program constant 8 was pre-set in the factory.

This factor links the retraction speed of the sprinkler with the pre- and
post-irrigation time. The adjusted factor can be changed, whereby pre- and
post-irrigation changes.

The following table shows the pre-and post-irrigation times in minutes
(rounded) at different adjustment factors:

9. EMERGENCY SHUT-OFF

If something unforseen happens, the pipe retraction can be interrupted with
the emergency shut-off. Pull the gear shift lever with the open hand from the
“PE-pipe retraction” position to the shut-off position (Do not operate the
lever with the closed hand or release it immediately !). The gearbox is
disengaged. A spring snubs the lever up (shut-off position) and the band brake
prevents fast reversing of the PE-pipe and the reel.
Manual for BAUER RAINSTAR Series E11-E51
53
Slacken the PE-pipe by pushing down the gear shift lever carefully.
10. WINDING MECHANISM
The winding mechanism operates synchronously with the winding or unwinding of
the PE-pipe. Starting from the reel it is operated through a chain and the
helically grooved spindle transporting the winding carriage of the PE-pipe.
The winding mechanism ensures that the PE-pipe is properly guided winding for
winding. When you put the machine into operation for the first time, pull off
the full length of the PE-pipe to let it take a circular shape under pressure
and eliminate ovality. This step is essential for trouble-free operation of
the winding mechanism.
Manual for BAUER RAINSTAR Series E11­E51XL
54
11. SHUT-OFF AND SAFETY EQUIPMENT

Unattended operation of the RAINSTAR is made possible by a final and safety
shut-off. The final shut-off is actuated when the sprinkler cart pushes
against the shut-off frame, which in turn operates the shut-off lever through
a system of rods. This way the drive is stopped. To avoid troubles caused by
faulty windings of the PE-pipe on the reel, the shut-off is also activated by
the shut-off frame when faulty pipe windings build up on the reel.
12. CART
The high construction of both symmetric and asymmetric wheel carts provides
maximum crop protection (Asymmetric wheel cart OPTIONAL). With infinitely
variable track width the carts adapt to any crop row spacing. The width is
symmetrically adjusted with the frame support member.
For easier PE-pipe pull-off the carts are equipped with a double draw-out
hook. You pick up this hook with the tractor’s toolbar and pull off the PE
pipe. To turn the pipe reel and re-position the RAINSTAR at ist new set-up
position, the cart must be pulled back into its end position at the RAINSTAR.

Depending on the type of sprinkler used, the nozzle height of the mounted
sprinkler ranges between 1960 and 2120 mm. At the end of the retraction, when
the cart moves up to the machine it is slightly hoisted on the PE-pipe side.
Owing to its pendulous mounting (self-balancing assembly) the sprinkler is not
tilted and always remains in the optimum position regarding distance of throw
and distribution uniformity. This pendulous mounting assembly compensates also
slopes in the terrain in longitudinal direction.

13. SHUT-OFF VALVE ­ OVERPRESSURE (OPTION)

With an overpressure shut-off valve, the water supply to the machine is
interrupted completely at the end of the irrigation run. When the valve
closes, pressure rises in the supply line.

Therefore this valve can only be used in combination with an automatic pump
shut-off device or in a line network supplying several machines. Before
starting up again, the valve is opened again by the electronic system.
14. SHUT-OFF VALVE ­ LOW PRESSURE (OPTION)

With the low pressure shut-off valve option, a shut-off valve is opened
quickly at the end of the irrigation run, releasing quite a big water stream
into the open. This causes a sudden pressure decrease in the supply line (to
about half the original pressure). Through this drop in pressure a pressure
switch shuts off the pumping unit and thus also the water supply. Therefore
this valve can only be used in combination with an automatic pump shut-off
device.
CAUTION!
The low pressure shut-off valve option can only be used if only one irrigation
machine is fed by the pumping unit. If several machines are fed simultaneously
by one pumping unit this low-pressure or underpressure shut-off valve cannot
be used !
Manual for BAUER RAINSTAR Series E11­E51XL
56
15. COMBINED SHUT-OFF SYSTEM
The combined shut-off combines the overpressure and low-pressure shut-off in
one system. The double connection allows both overpressure and low-pressure
shut-off at the end of the irrigation strip.

16 WINTERIZATION – DRAINING

In areas, where frost is likely in winter after the irrigation season, the
machine must be drained in time. werden. A compressor with a minimum air
capacity of 5000 l/min at 1,5 bar overpressure is best suited for this
purpose. Connect the compressor to the inlet of the machine For blowing out
the water the PE-pipe should not be pulled off. It can stay on the reel. In
most cases, winding up the empty PE-pipe after the draining will cause extreme
ovality and faulty winding. The small amount of water remaining in the PE-pipe
after the draining (approx. 30 to 50 % of the volume) will not do any harm.
Turn out the drain plug on the bottom of the TVR 60 turbine. We recommend to
turn it in again only when you start up the machine again at the beginning of
the next season. Clean the RAINSTAR and regrease all appropriate points. The
machine should preferably be stored in a roofed shelter where it is protected
from direct exposure to the weather.

Open the drain valve on turbine

Drain screw for gear oil.

Oil or grease the jack.

16.1 DRAINING THE PE-PIPE

WITH THE BAUER BLOW-OUT AND COMPRESSOR UNIT

Note the following instructions to ensure proper function of the blow-out
unit:

1. The blow-out must be performed before further transport of the machine to
ensure that no water is drained from the PE pipe.
CAUTION!
If parts of the PE-pipe have run empty and air bubbles are enclosed in the
pipe, the blow-out will not work !
2. If you use an electric shut-off valve, press the menu button ,,START” so
that the valve opens. 3. Connect a drain pipe at the inlet of the machine to
avoid soaking the machine’s standing position.
CAUTION!
If you use the supply hose (7) for draining, make sure that the hose is not
kinked and the water can run off freely.
PROCEDURE:
The PE pipe is wound up on the reel, the cart is just before the shut-off
position, take off the end cap (with bore

and baffle plate) from the ,,garage” (1). Press the plastic ball in the
“garage” down by hand or with a piece of wood until the ball gets to lie in
the straight horizontal pipe (2) behind the outlet to the sprinkler.
Close the shut-off vale (3) to the sprinkler..
Connect the pipe bend 90° (4) to the coupling ,,garage” (1) and the compressor
hose (5) to the pipe bend (4) and the compressor (6).
The PE pipe can now be drained with the help of the compressor.
Technical specifications of the compressor:
Type B33
Operating pressure:
1,5 bar sufficient
Air capacity:
minimum 5000 litres at 1,5 bar
Type B83 (from 2017)
Operating pressure:
3,0 bar sufficient
Air capacity:
minimum 8000 litres at 3,0 bar
It does not take more than 5 to 8 minutes to drain the PE-pipe. If the blow-
out takes longer, there are already air bubbles in the pipe that prevent
further draining.
Manual for BAUER RAINSTAR Series E11-E51
59
ATTENTION!
After the blow-out and before opening the coupling, open the valve (3) so that
the pressure in the PE pipe can escape !
Remove the fittings with the hose and couple the end cap with the baffle
plate. The blow-out ball is in the inlet bend to the reel and the water will
carry it back to the ,,garage” (at the end of the horizontal pipe), when you
resume irrigation.

16.1.1 POSSIBLE FAULTS DURING PE-PIPE BLOW-OUT WITH COMPRESSOR
Fault PE-pipe has run empty. Kink in the drain hose from the turbine. Shut-off
valves not opened. Plastic ball not in the correct position. Incorrect plastic
ball diameter.

Plastic ball damaged. Insufficient compressor output.
Remedy
Put the irrigation machine under pressure again until a full jet without air
bubbles is discharged at the sprinkler.
Lay the hose straight without kinks or connect a rigid pipe.
Open shut-off valves.
Push down the plastic ball far enough to place it in the straight horizontal
pipe
Required ball diameter:
PE-pipe dia. 100mm : Ball : 100mm
110mm :
: 100mm
120mm :
: 110mm
125mm :
: 125mm
The ball must be round and faultless.
Check compressor performance data and safety valve
CAUTION!
The end cap on the branch pipe of the horizontal pipe (,,”Garage” of the
plastic ball) must have a vent bore through which the branch pipe is deaerated
when the ball is pressed to the cart by the water pressure from the turbine
side. Then the plastic ball will park properly in the ,,”garage” during
irrigation. If this vent bore is missing, the plastic ball remains in the area
of the horizontal pipe during irrigation and may cause considerable pressure
loss on account of the reduced cross section..
