Once the pump has been filled (par. 2.1.2, 2.2.3) and the device has been configured (par.
3.2), it is possible to connect the electric power supply after having opened at least one
utility on delivery for the first 10 seconds.
If a flow of water is detected in delivery, the pump is primed and starts its regular work.
This is the typical case of installation below head (par. 2.1.2, 2.2.3). The utility opened in
delivery from which the pumped water is coming out can be closed.
If a regular flow in delivery is not detected after 10 seconds, the system asks for confirma-
tion to enter the priming procedure (typical case of installation above head pa 2.1.2, 2.2.3).
Or:
When "˄" is pressed the pump enters the priming procedure: it starts working for a maxi-
mum time of 5 minutes during which the safety block for dry operation is not tripped. The
priming time depends on various parameters, the most influential of which are the depth
of the water level from which it is drawing, the diameter of the suction pipe, the water-
tightness of the suction pipe. On condition that a suction pipe is used that is no smaller than
1" and that it is well sealed (with no holes or joins from which it can take in air), the product
has been studied to manage to prime in water conditions up to 8m in depth in a time of
less than 5 minutes. As soon as the product detects a regular flow in delivery, it leaves the
priming procedure and starts its regular work. The utility opened in delivery from which the
pumped water is coming out can be closed. If after 5 minutes of the procedure the product
is still not primed, the interface display sends a failure message. Disconnect the power
supply, load the product adding new water, wait 10 minutes and repeat the procedure from
the moment you put the plug in the socket.
Press "˅" to confirm that you do not want to start the priming procedure. The product
remains in alarm status
Operation
Once the electropump is primed, the system starts regular operation according to the con-
figured parameters: it starts automatically when the tap is turned on, supplies water at the
set pressure (SP), keeps the pressure constant even when other taps are turned on, stops
automatically after time T2 once the switching off conditions are reached (T2 can be set by
the user, factory value 10 sec).
4 - THE KEYPAD AND THE DISPLAY
Figure 12: Aspect of the user interface
The user interface is composed of a keypad with 128x240 pixel LCD display and with
POWER, COMM, ALARM warning leds as can be seen in Figure 12.
The display shows the values and the statuses of the device, with indications on the func-
tionality of the various parameters.
The functions of the keys are summed up in Table 1
The MODE key allows you to move on to the next items in the same menu. Holding it
down for at least 1 sec allows you to skip to previous menu item.
The SET key allows you to leave the current menu.
Decreases the current parameter (if it is an editable parameter).
