CAUSE
No water intake, intake
obstructed, fault on pressure
sensor.
The pump cannot manage
to provide the pressure
requested, on closure).
The working pressure is lower
than the minimum safety
threshold.
The voltage reaches peaks
under the minimum use
voltage.
The inverter was placed out of
service from remote.
Short circuit or current
dispersion in section that
goes from the module to the
motor of the pump.
Continuous overcurrent, with
possible motor problem.
The module does not cool
correctly or is damaged.
Pressure signal wrong or
missing.
Flow signal wrong or missing. Check/replace the flow
The valve has remained open
due to foreign body.
The expansion tank is
deflated or damaged and
does not keep the circuit
pressurised.
The fuse has blown.
INTERVENTION
Run the relevant checks.
Check the maximum pressure
of the pump and correct the
Pset.
Check there are no broken
tubes, insert a valve that
adjusts the flow.
Power the inverter with the
line separate, insert a
voltage stabiliser.
Put back in service from
remote.
Check isolation of cable and
motor. Try
the inverter disconnected
from the motor.
Check motor in direct
operation.
Check the water passes in the
inverter.
Check/replace the pressure
sensor.
sensor.
Extract the check valve:
check/clean.
Check the expansion tank.
Replace the fuse.
