Operation manual for
BAUER RAINSTAR
Series T32, T42

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.
7.7.3 START
If the PE – pipe has been pulled off and the desired speed has been set you can start the irrigation with the
“START–RESET“
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 „START–RESET“ 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.
7.7.4 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.
