13. ALARMS

MESSAGE
ALARM F01
OVERCURRENT
REASON
The start-up wizard is running.
The pump is in a state of alarm
(indicated on the display).
The frequency converter is limiting the
rotational frequency of the motor due to
a high temperature in the electronics, in
addition to excessive consumption of the
electric motor.
The stop frequency calculated exceeds
the maximum frequency permitted for
pump operation (5.08).
The frequency converter is limiting the
rotational frequency of the motor due to
excessive consumption of the motor.
The frequency converter with this
warning does not have any pressure
transducer connected.
If there is a transducer connected, it is
not connected with the correct polarity.
The transducer's reading has a difference of
0.5 bar from the other transducers connected
on the network of frequency converters
REASONS
Indicates excessive consumption in the
motor.

ENGLISH
EXPLANATION / SOLUTION
The LED will stop blinking once the initial
configuration wizard has finished.
Consult the section on Alarms in this
manual to resolve the incident.
Consult the section on Alarms in this
manual to resolve the incident.
Check the frequency converter is
properly ventilated.
We recommend running the stop
frequency setup wizard again (5.24).
If this warning persists after running the
wizard again, you must reduce the
working pressure, as the pump that is
connected will not be able to reach it.
Check that the motor current (1.2) is
that indicated on the specifications plate.
Disconnect the transducer from the
electrical terminal block and invert the
polarity of the connecting cable.
We recommend changing the transducer
because it is not reading correctly.
SOLUTION(S)
Check that the nominal consumption
data has been entered correctly.
Check that the pump rotates freely with
no obstructions.
