PRESSURE PARAMETERS
REASONS
The motor is communicated or has
burnt out.
Fault/poor connection of the phases
The frequency converter detects that the
pump is working partially at no load.
The frequency converter detects that the
pump is working at a very low pressure
and at a speed high for a time.
There is a parameter related to the
frequency in conflict with the values
considered normal.
The stop delays of the auxiliary pumps
exceeds the stop delay of the main
pump.
The start-up pressure differential
exceeds the working pressure.

SOLUTION(S)
Disconnect the motor from the frequency
converter 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
frequency converter.
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.
Check that the minimum frequency is
greater than 10 Hz.
Check that the minimum 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.
Reduce the start-up pressure differential
of the pump, or increase the working
pressure above this value.
