Operation manual for BAUER RAINSTAR Series T32, T42 66
14 OPTIONAL EQUIPMENT
14.1 OVERPRESSURE SHUT-OFF VALVE (OPTIONAL ON ECOSTAR)
With the overpressure shut-off valve, water supply to the machine is turned off completely at the end of the
irrigation run.
a) When the cart reaches the shut-off position or when the machine is turned off by means of a pressure
switch (optional), the overpressure shut-off valve closes in response to an electrical pulse from the
ECOSTAR.
b) The shut-off valve closes slowly in order to avoid pressure shocks.
c) Pressure in the supply line increases. The pump must be shut off automatically by means of a pressure
switch (or flow control).
14.2 LOW PRESSURE-SHUT OFF VALVE
With the low pressure shut-off valve a shut off valve is opened quickly after the irrigation process and a high
amount of water is being drained out. The pressure in the discharge line is being reduced drastically (almost
half of). Due to the loss of pressure the pumping aggregate is being switched off by a pressure switch and
the pumping is being stopped. This valve can only be used in combination with a pressure switch for the
automatic shut off installation for the pump.
.
CAUTION!
The low pressure shut off valve can only be used if only one irrigation machine is
being supplied by the pump. If more than one machines are supplied by the pump
the low pressure shut off valve cannot be used!
