PRECISE DETECTION OF WATER INSUFFICIENCY (DIAGRAM C)
In the DIGIPRESS model simply introduce the nominal pump current to activate the protection for overcurrent and
insufficient water (see STARTING point 2).
However, it is possible to improve the detection precision for insufficient water activating ADVANCED
PROGRAMMING MENU, the dr1 parameter, proceeding as follows:
• Firstly check, when the system
is without water, that the hydro-
pneumatic tank is inflated at the
required pressure. Then when
the system is loaded, or at the P
stop pressure:
• Enter the ADVANCED
PROGRAMMING MENU
When replacing with a new pump it will be necessary to repeat the process.
Having accessed the current menu by pressing
introduced nominal current predominates.
PRESSURE SENSOR CALIBRATION
In the case of misreading by the sensor, recalibration is possible.
For calibration of the sensor it is necessary to have a pressure gauge installed.
Steps to follow:
PRESSURE CALIBRATION = 0
1. Open the valves to obtain
depressurised installation.

1. Start the pump until the

It appears if in normal operation the pressure is below minimum pressure (Px. x) previously set
during the time
(txx) pre-set in the ADVANCED MENU. If the pressure exceeds the minimum pressure, the ope-
ration is automatically reset and the alarm disappears. Normal operation can also be restored
manually by pressing
The overcurrent alarm is activated if the nominal current of the pump is exceeded. The device
performs 4 automated attempts at reset before entering definitive alarm. Normal operation
can also be re-established manually b pressing
Only if activated in the ADVANCED MENU the alarm is generated after three consecutive cyc-
les in a time range less than that set. If rc1 is reactivated, the device does not stop and5 delay
seconds are added for start to protect
the electric pump. If rc2 is activated, the electric pump is stopped. \To end the display on the

USE AND MAINTENANCE MANUAL
• Open the utility valves and run
water for approximately 15 sec
and then close them.
• The pump will fill the system and
will stop once the stop pressure
P value already set is reached
(see STARTING point 4).
• DIGIPRESS learns the value of
absorbed pump current.
