9.2 Description of the functions

9.2.1 Pump ON/OFF (AUTO MODE, MANUAL MODE)

Cut out disabled  on inserting the plug after the test on the LEDs the pump switches on for 10 seconds.
Cut out enabled  after the plug is inserted, the test is conducted on the LEDs for the first 3 sec (LED 0 indicates that
the power is always On) and the "AUTO MODE" is set as default with the indicator "ON". The pump will start working if
the pressure is less than the CUT –IN value and the flow is less than the minimum cut-in flow. The pump will continue to
operate as long as the pressure remains less than the CUT-OUT value, and will switch off when this value is reached,
independently of the flow.
While, if the "MANUAL MODE" is selected, by pressing once the "MODE", the pump will start up if the "ON" LED lights
up, otherwise, if "SET" is pressed, the pump will switch itself off and the "OFF" LED will light up.
When the pump starts working, it will enter the PRIMING mode.
NOTE: Make sure the instructions for installation have been followed and that the pump is filled completely with water.

9.2.2 Priming phase

When the pump starts working, it will enter the priming mode, during this phase if there is no flow and pressure the motor
will remain switched on for 3 minutes after which it will enter dry run alarm. But if flow and pressure are present during
this phase, priming will be carried out and the pump will work normally.

9.2.3 Alarms reset

When there is an alarm, the red indicator on "ALARM" lights up. The alarm is reset by pressing "SET" once; if the cause
of the alarm is eliminated, normal operation continues, otherwise the pump will return to alarm condition.

9.2.4 Power ON/OFF indicator

If power supply is present the pressure LED 0 on the LED bar lights up. If there is no power the LED remains switched
off.
Note: for long shutdowns it is advisable to disconnect the plug from the power supply.

9.2.5 Pump On/off indicator

When the motor is running, a "PUMP ON" blue light must be On to indicate this status. When the motor stops, this LED
switches off.

9.2.6 Alarms indication

A steady red light or button on "ALARM" is activated when an alarm is present.
Dry-running: steady red light
Leakage: slow pulse
Max Pump ON (pump running for more than 30 minutes): 2 quick flashes separated by a longer pause.
Press "SET" button to reset the alarms.

9.2.7 Dry running protection

If the pump is running dry, after a few seconds (40 sec.) it is stopped and an error indication appears with the steady red
light on "ALARM".
After the initial 30 min when the pump is OFF a new restart attempt is made lasting 5 min. If this attempt is not
successful, another attempt will be made every 30 min, up to a maximum of 48 times. If all these attempts fail, an attempt
will be made every 24 hours.
The device automatically comes out of the Dry-running alarm status if the flow and/or pressure is restored.
