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 four conditions:
- turning the starter key onto "ZERO”
- protection intervention
- timer intervention at the end of the work period
- 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

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.
