21.1. Troubleshooting for Embedded Electronics
Before starting to look for faults it is necessary to disconnect the power supply to the pump.

ENGLISH
Air getting into
•
suction pipe.
Faulty flow sensor
•
Suction depth too high.
•
Suction pipe clogged or
•
diameter insufficient.
Impeller or hydraulic part
•
clogged.
Leak in the system.
•
Faulty non-return valve.
•
Expansion vessel empty
(insufficient air pressure) or
has broken diaphragm
Air pressure in the expansion
vessel higher than the system
starting pressure
Probable Causes
No water.
•
Pump not primed.
•
Setpoint not reachable
•
with the set RM value
Faulty pressure sensor
Faulty pressure sensor
Excessive absorption.
•
Pump blocked.
•
Supply voltage too low.
•
Excessive drop
•
voltage on the line.
One or more devices have
sensitive parameters
aligned.

the Check the suction pipe, find and eliminate the cause
•
of air getting in.
Contact the assistance centre.
•
As the suction depth increases the hydraulic
•
performance of the product decreases (par. 12).
Check whether the suction depth can be reduced.
Use a suction pipe with a larger diameter (but never
•
smaller than 1").
Check the suction pipe, find the cause of choking
•
(obstruction, dry bend, counterslope,...) and remove
it.
Dismantle the system and remove the obstructions
•
(assistance service).
Check the system, find and eliminate the leak.
•
Service the non-return valve as described in par. 20.
•
Check the air pressure through the valve in the technical
compartment. If water comes out when checking, the
vessel is broken: assistance service. Otherwise restore the
air pressure according to the equation par. 18.
Calibrate the expansion vessel pressure or configure the
parameters SP and/or RP so as to satisfy the equation (par.
18).
Remedies
Prime the pump and check whether there is air in the
•
pipe. Check whether the suction or any filters are
blocked.
Set a RM value that allows the setpoint to be reached
•
Contact the assistance centre
Contact the assistance centre
Fluid too dense. Do not use the pump for fluids other
•
than water.
Contact the assistance centre.
•
Check the presence of the correct supply voltage.
•
in Check the section of the power supply cables.
•
Press the key on the device which we are sure has
not
the most recent and correct configuration of the
parameters.
