DO NOT EXPOSE THE IPG20 Mk2 TO VIBRATION. INSTALL ONLY IN
PIPEWORK THAT DOES NOT VIBRATE.
Vibration will damage the
electronics within the IPG20 and will void your product warranty.
OVERVIEW
The IPG20 Mk2 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 parameters 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.
