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.
If the alarm is reset, see 9.2.3, a new attempt will be made after 40 sec.
Eliminate the causes and reset the alarm see 9.2.3.
9.2.8 ANTI-LEAKAGE
The function may be enabled or disabled. When enabled, if the condition is such that the pump is started up more than 6
times in 2 minutes, it will be stopped and the error will be indicated by means of the red LED flashing slowly on "ALARM".
Eliminate the causes and reset the alarm see 9.2.3.
For the enabling procedure see Anti-leakage.
9.2.9 Max pump on
Maximum operating time. The function can be enabled or disabled. Factory setting is disabled. When enabled, if the
condition is such that the pump works for more than 30 minutes, it will stop, and the ALARM light will flash.
This function is used to protect the installation if the valve is accidentally left open, in case of breakage of a pipe, or in
applications for irrigation.
9.2.10 Pressure sensor alarm
The pressure sensor alarm of the device is activated if the pressure value is outside the operating range ( 0-15 bar). The
pump is switched off, the error will be reset as soon as the pressure conditions return within the range.
9.3 First start up
9.3.1 Test on LEDs
When the device is started up the first time, or after the plug is inserted in the power socket, the Test is conducted on the
20 LEDs, for a few seconds during which all the LEDs will light up in sequence.
9.3.2 First priming
The pump will automatically be in AUTO mode set to ON.
There may be three possible behaviours:
1)
Flow present but low pressure: exits the priming phase and starts normal operation.
2)
Pressure present but no flow: after 10 sec. in this condition the pump will switch itself off.
3)
No flow no pressure: the pump will switch itself off and the Dry-running error will be displayed after about 3.
minutes, indicated by the red LED in SET-ALARM. Eliminate the cause and reset the alarm see 9.2.3.
9.4 Normal operations with CUT-OUT disabled (factory setting)
Cut-out disabled means the following behaviour is present:
The pump is activated if there is flow or pressure is absent, pressure is less than CUT IN (in 10 ms).
The pump is stopped if the pressure is present but Flow is absent continuously for 10 s.
The CUT OUT LED will be switched off during normal operation. To modify the setting see 9.1.1.B.
9.5 Normal operations with CUT-OUT enabled
Cut-out enabled means the following behaviour is present:
The pump is activated if the pressure is less than the CUT IN pressure.
The pump is stopped if the pressure is higher than the CUT OUT pressure.
The CUT OUT will be switched on during normal operation. To modify the setting see 9.1.1.B.
10. PRECAUTIONS
RISK OF FROST: when the pump remains inactive at a temperature lower than 0°C, it is necessary to ensure that there
is no water residue which could freeze, causing cracks in the plastic parts.
If the pump has been used with substances that tend to form a deposit, or with water containing chlorine, rinse it after use
with a powerful jet of water in order to avoid the formation of deposits or encrustations which would reduce the
characteristics of the pump.
11. MAINTENANCE AND CLEANING
In normal operation the pump does not require any type of maintenance. In any case, all repair and maintenance work
must be carried out only after having disconnected the pump from the supply mains. When restarting the pump, ensure
that it has been correctly reassembled, so as not to create a risk for persons and property.
