ALARM F02
SHORT CIRCUIT
The motor is communicated or has
burnt out.
Not all wires have been connected.
Internal fault in the frequency converter.
Disconnect the motor from the frequency
converter and check that the message
disappears. If this is not the case, contact
your nearest technical service.
Check that all the cables of the motor are
correctly connected to the motor itself
and also to the frequency converter.
Also supervise the correct wiring of the
frequency converter’s power supply.
Contact your nearest technical service.
ALARM F03
EXCESS TEMPERATURE
OF THE MODULE
The power module has reached a very
high temperature, compromising its
reliability.
Ensure the ambient temperature does
not exceed the extremes set out in this
manual.
If it is assembled on the pump, ensure
the pump has a fan and that the fan
cover has been fitted.
If it is assembled on a wall mount,
ensure the fan of the mount functions
correctly when the motor is running.
ALARM F04
INPUT
VOLTAGE
The frequency converter is not receiving
electric current, of is outside of the upper
and lower limits.
The electrical supply to the frequency
converter has been interrupted.
The electrical connection cable from
the mains electricity to the frequency
converter has been disconnected.
The electrical voltage entering the
frequency converter is outside the limits
specified in the technical data section.
ALARM F05
TRANSDUCER
The frequency converter does not
receive a correct reading from the
pressure transducer.
The pressure transducer is wired in the
frequency converter with the polarity
reversed.
The pressure transducer is broken.
The pressure transducer has a range
other than 4-20 mA.

SOLUTION(S)
ALARM F01
OVERCURRENT
Indicates excessive consumption in the
motor.
Check that the nominal consumption
data has been entered correctly.
Check that the pump rotates freely with
no obstructions.
