The pump protection is enabled with the switching on of the ACTIVE PUMP PROTECTION (after 2 consecutive
minutes of stable water pressure, indicated by the visual signal REGULAR PUMP PRESSURE and, in any
case, 10 minutes after the start of the motor pump)
The intervention of the protection (5 seconds after the increase or decrease of the pressure) stops the engine and
is indicated by the visual signal for LOW PUMP WATER PRESSURE or
WATER PUMP OVERPRESSURE .
The control unit shuts down the engine in five conditions:
- turning the starter key onto "ZERO”
- protection intervention
- timer intervention at the end of the work period
- giving the command from a cell phone
- through intervention of the external emergency.
The unit adapts to two different stop systems
- by working the ELECTROMAGNET for 20 seconds which pulls the STOP lever
- by cutting off power to the SOLENOID VALVE shutting off the flow of fuel.
It can be obtained in all functioning conditions, mounting one or more release-type buttons. It is indicated by the
visual signal and enables the general alarm.
This can be obtained by fitting on the outside an optical and/or acoustic signaller to be connected to the RED/GREEN
wire. It is activated on protection intervention.
!
The control unit comprises six instruments:
INSTRUMENTS WHICH CAN BE SELECTED IN SEQUENCE BY PRESSING THE BUTTON
HOUR METER - Total hours of operation (with the engine running the signal pulsates, to
indicate the correct functioning of the HOUR-METER).
Each time it is pressed, IT SHOWS the next instrument. WHEN THE TIMER IS set, the duration of the display of
the instrument is limited to 30 seconds from the activating of the button; the TIMER then reappears.

ONTROLLING THE CONNECTION OF THE PUMP WATER
ELECTRONIC PRESSURE GAUGE (Transmitter)
Turning the key to the AUT position stops the electronic pressure gauge.
Control is activated 1 minute after the completion of the starting pulse.
Intervention is highlighted by the relevant indicators flashing warning light
and stops the motor pump after 2 seconds.
To exclude intervention, press the push-button PUMP PROTECTION EXCLUSION.

It is not possible to restart the motor pump with the key in the 'zero' position.
Restarting is possible after the pump has been stopped by cell phone or timer.
AUTOMATIC RESTART WITH CELL PHONE
Before the start, the internal annunciator sounds for 8 seconds, and, after a 3 second pause, startup begins. To
facilitate startup, a special circuit emits a series of four, 5-second pulses, with a 5-second delay between each pulse.
START UP FAILURE
Blocks the startup cycle if the pump has not started up after the fourth pulse.
Simultaneously press four buttons (for at least 5 seconds): the word appears on the display.
Release the buttons, and for 10 seconds the display will show the most recent anomaly that caused the pump to stop.
