Pump available to run
The Pressure switch is
registering line pressure
above the cut-out
pressure. The switch
circuit is open
If there is sufficient liquid at
the source the pump will start
The Pressure switch is
registering line pressure
below the cut-in pressure.
The switch circuit is closed
If there is sufficient liquid at the source
the pump will start
In BOOSTING mode, terminals 10 and 11 are the main control inputs.
Circuit closed = ON. Circuit open = OFF.
The user can exploit this knowledge to control the pump with an external device such as a
timer or connection to an irrigation control unit. A relay may be necessary.
Never connect 240V supply to control terminals
1 – 12 or to N1, N2 or C
When the iProtect is used in BOOSTING
MODE and the pump is controlled by a
pressure switch, ensure that a suitably
sized pressure vessel is installed in the
system.
A Pressure vessel sized properly and
set with the correct pre-charge
pressure is intended to prevent the
pump from starting more than 30 times
per hour (20 times per hour for bore
pumps)
Pressure tank pre-charge should be set
to 66% of full system pressure
Pump calibration:
