Ch. 6 Operation of the FLUSSCONTROL electronic pressure switch (Fig. 1, n. 12)
AUTOMAX 80/48, AUTOMAX 160/120, AUTOJET 60/50, AUTOJET 70/50
A panel is mounted on the front of the device which displays all the operating phases of the system by means of pilot
lights: green pilot light Power on, yellow pilot light Pump on, red pilot light Failure. At the moment of connection to the
electrical mains, the green light turns on together with the yellow light indicating the start-up of the pump (fig. 5/A) which
remains in operation for a few seconds in order to allow the system to build up pressure. If this time is not sufficient,
the red Failure light will turn on (fig. 5/C); in this case keep the red Restart (rearm) button pressed and wait with a
service open for the red pilot light to turn off. After the service is closed, the device stops the pump and goes into
standby mode, the green pilot light lit, ready to carry out in complete autonomy all the subsequent command and
control operations (fig. 5/B).
On opening a service, the device starts the pump which remains in operation for as long as the service itself is open
(fig. 5/A). After the service has been closed, the device restores maximum pressure to the system, then stops the
pump and returns to the standby mode (fig. 5/B). In the event of water shortage during aspiration, the device
recognises the failure which it signals with the red Failure light, and stops the pump (fig. 5/C) protecting it from dry
running. Once the causes of a blockage have been removed, it is sufficient to press the red Restart (rearm) button to
restore normal operation. In the case of a temporary power outage the device will automatically restart as soon as the
electricity returns.
The electronic FLUSSCONTROLL pressure switch (including the
safety cables) can be opened or replaced only by qualified
personnel.

Make sure that the pump and the electric connections are protected from possible inundation.
Before using the pump, always inspect it visually (especially power cable and plug).
Do not use the pump if it is damaged.
If the pump is damaged, have it inspected by the specialised assistance service only.
Do not transport the pump using the cable or use the cable to remove the plug from the socket. Protect the plug and the
power cable from heat, oil or sharp edges.

The power cable must be replaced by qualified personnel only.
Start-up (Fig. 1)
Before starting the pump, fill the suction pipe
(2)
and the pump body
(8)
using the filling cap
(9)
. Close the cap after
verifying that there are no leaks. Open the closing devices on the delivery pipe (i.e. the water cock) so that air can be
released from the suction cycle.
Insert the pump plug into a 230 V alternate current socket and press the switch.

are self-priming. Therefore, it is possible
to start them without filling the suction pipe with water. However, it is still necessary to fill the pump body. The priming
operation requires a few minutes. It may also be necessary to fill the pump body with water several times, according
to the length and diameter of the suction pipe. If the electropump is not used for a long period of time, it is necessary
to repeat all the operations described above before starting the pump.
