3.3 - Priming
The priming of a pump is the phase during which the machine attempts to
fill the body and the suction pipe with water. If the operation is successful
the machine can work regularly.
Once the pump has been filled (par. 2.1.2, 2.2.3) and the device has been
configured (par. 3.2), it is possible to connect the electric power supply
after having opened at least one utility on delivery.
The system starts and checks the presence of water in delivery for the first
10 seconds.
If a flow of water is detected in delivery, the pump is primed and starts its
regular work. This is the typical case of installation below head (par. 2.1.2,
2.2.3). The utility opened in delivery from which the pumped water is com
-
ing out can be closed.
If a regular flow in delivery is not detected after 10 seconds, the system
asks for confirmation to enter the priming procedure (typical case of instal
-
lation above head par. 2.1.2, 2.2.3).
Or:
When “+” is pressed the pump enters the priming procedure: it starts work
-
ing for a maximum time of 5 minutes during which the safety block for dry
operation is not tripped. The priming time depends on various parameters,
the most influential of which are the depth of the water level from which it
is drawing, the diameter of the suction pipe, the water-tightness of the suc
-
tion pipe. On condition that a suction pipe is used that is no smaller than
1” and that it is well sealed (with no holes or joins from which it can take in
air), the product has been studied to manage to prime in water conditions
up to 8m in depth for e.sybox and 7 m for e.sybox 30/50 in a time of less
than 5 minutes. As soon as the product detects a regular flow in delivery, it
leaves the priming procedure and starts its regular work. The utility opened
in delivery from which the pumped water is coming out can be closed. If
after 5 minutes of the procedure the product is still not primed, the interface
display sends a failure message. Disconnect the power supply, load the
product adding new water, wait 10 minutes and repeat the procedure from
the moment you put the plug in the socket.
Press “-“ to confirm that you do not want to start the priming procedure.
The product remains in alarm status
Operation
Once the electropump is primed, the system starts regular operation ac
-
cording to the configured parameters: it starts automatically when the tap
is turned on, supplies water at the set pressure (SP), keeps the pressure
constant even when other taps are turned on, stops automatically after
time T2 once the switching off conditions are reached (T2 can be set by
the user, factory value 10 sec).
4 - PROTECTION SYSTEMS
IThe device is equipped with protection systems to preserve the pump, the
motor, the supply line and the inverter. If one or more protections trip, the
one with the highest priority is immediately notified on the display. Depend
-
ing on the type of error the motor may stop, but when normal conditions
are restored the error status may be cancelled immediately or only after a
certain time, following an automatic reset.
In the case of blockage due to water lack (BL), blockage due to motor over
-
load (OC), blockage due to direct short circuit between the motor phases
(SC), you can try to exit the error conditions manually by simultaneously
pressing and releasing the + and – keys. If the error condition remains, you
must take steps to eliminate the cause of the fault.
In the event of blocking due to one of the internal errors E18, E19, E20,
E21 it is necessary to wait 15 minutes with the machine powered until the
blocked status is automatically reset.
