ALARM F06
MOTOR FAULT
ALARM F07
LOW WATER LEVEL
ALARM F08
BURST PIPES
The motor is short circuited or has burnt out.
Fault/poor connection of the phases
The Inverter detects that the pump is working partially
at no load.
The Inverter detects that the pump is working at a very
low pressure and at a speed high for a time.
Disconnect the motor from the Inverter and check that
the message disappears. If this is not the case, contact
your nearest technical service.
Some of the cables that communicate the motor with
the frequency converter are not making good electrical
contact.
The motor is connected to receive a voltage other than
that provided by the Inverter.
The consumption of the input phases is not balanced.
Ensure the pump aspirates the fluid correctly.
Check that the water network has no leaks greater than
those required for regular demand.

INTERNAL ERROR
ALARMA X14
INTERNAL ERROR
The stop delays of the auxiliary pumps exceeds the stop
delay of the main pump.
The start-up pressure differential exceeds the working
pressure.
The detected value of the NTC or PTC thermistor is higher
or lower than the indicated value.
The alert threshold indicated in the section relating to
overpressure alert level has been exceeded.
There is no communication between the control panel
with the button pad and display, and the power plate
screwed into the radiator.
Internal fault in the Inverter.
The communication between electronic boards of the
same drive, or the information shared between drives has
failures or data integrity errors.
Reduce the start-up pressure differential of the pump, or
increase the working pressure above this value.
Wait for the Motor to cool down.
Check PTC or NTC cable connection.
Check the overpressure warning alert level.
Check that the flat cable that communicates both
electronic circuits are well connected and tightened.
It may be due to an occasional error in the firmware of
the Inverter or the spot reading of a parameter deemed
to be outside of the limits. In this case we recommend
cutting the power to the Inverter for a few minutes. If
after a few minutes, when the power is reconnected
to the Inverter, the message remains, contact your
nearest technical service.
Check that the flat cable that communicates both
electronic circuits are well connected and tightened.
Check that the cables connectingthe drives are correctly
wired and tight.
It may be due to an occasional error in the firmware of
the Inverter or the spot reading of a parameter deemed
to be outside of the limits.
This error is self-resetting, so the system will usually
return to normal after a few minutes.
ALARM A09
FREQUENCY PARAMETERS INCOHERENT
There is a parameter related to the frequency in conflict
with the values considered normal.
Check that the minimum frequency is greater than 10 Hz.
Check that the maximum frequency is lower than 65 Hz.
Check that the minimum frequency entered is lower than
the maximum frequency.
Check that the minimum operating frequency for the
auxiliary pumps is lower than the maximum frequency.
Check that the minimum operating frequency for the
auxiliary pumps is greater than the minimum frequency.
