The IPG20 MK3 intelligent pump guard is a pressure and flow based device
that “learns” the operating pressure each time the system is started. This
allows for finely targeted parametres where any significant variation in the
operating pressure or loss of flow will trigger an alarm and shut the system
down.
Because the operating pressure will change each time the irrigator or pods
are moved to a different hydrant or hydrant group, or even a different height
on the same hydrant, it is normally impossible to give a high degree of
protection against over pressure due to a blockage or low pressure due to a
leak. With the IPG20, each time the pumping system is started and after the
operator has verified the system is running with no problems, the learning
phase of the controller can be instigated, either manually, or automatically,
after a suitable time. The controller then starts to “learn” the operating
pressure. If a stable pressure is reached within the allotted time the switch
will lock this pressure in as the set point and apply the predetermined under
and over pressure settings. If there is no expected change of pressure; eg.
fixed sprinklers, stationary irrigator or irrigator on flat land, then the low
pressure and high pressure margin can be set very close to the set point.
With a travelling irrigator Auto Terrain Compensation should be selected.
The switch then adjusts itself automatically to compensate for changes in
contour. This allows for a very small over and under margin, typically 10kPa
or less, which gives a very high degree of protection against leaks or
blockages.
Vibration will damage the
electronics within the IPG20 and will void your product warranty.
