• Check the CONF.MOTOR menu setting of COSFI MIN.
• In the 400V~ three-phase model, check that the pump rotates correctly.
• Self-resetting alarm (repeated attempts for REC TIME).
• Check the connection and/or operation of the ow sensor connected to IN1
(see )
The VSP on start-up of the pump goes to
protection due to "CIRCU.OPEN” alarm
on pressure transducer.
• Check that the transducer is connected correctly and that the cables are not
damaged.
• Check the transducer state.
• Self-resetting alarm.
The VSP on start-up of the pump goes to
protection due to "SHORT CIRCUIT” alarm
on pressure transducer.
• Check that the transducer is not shorted and that the cables are not damaged.
• Check the transducer state.
• Latching alarm.

ERROR alarm.
Only for VSP TRI (three-phase)
• Check the phases are correctly connected or that the power cables are not
damaged.
The VSP on start-up of the pump goes
to protection due to input overvoltage
alarm “MAX.VOLTAGE”.
• Check the input voltage for some reason has not increased in value, or the
VSP is not connected to an inadequate power system (400V instead of 230V).
• Check the condition on the power cables.
• Latching alarm.
The VSP on start-up of the pump goes
to protection due to input overvoltage
alarm “PFC.IN.HIGH”.
• Check the input voltage for some reason has not increased in value, or the
VSP is not connected to an inadequate power system (400V instead of 230V).
• Check the condition on the power cables.
• Latching alarm.
The VSP on start-up of the pump goes
to protection due to input undervoltage
alarm “MIN.VOLTAGE”.
• Check the input voltage for some reason has not decreased in value, or the
VSP is not connected to an inadequate power system (230V instead of 400V).
• Check the condition on the power cables.
• Latching alarm.
The VSP on start-up of the pump goes
to protection due to input undervoltage
alarm “PFC.IN.LOW”.
• Check the input voltage for some reason has not decreased in value, or the
VSP is not connected to an inadequate power system (230V instead of 400V).
• Check the condition on the power cables.
• Latching alarm.
The display does not switch on or goes to
"LCD ERROR” alarm.
• Check that the FLAT cable is connected correctly.
• Check that the FLAT cable is not damaged.

protection due to "NO_COM” alarm
• Check correct power supply on the interface board.
• Latching alarm
• If the alarm persists, contact your nearest technical support centre for power
board replacement.
The VSP on start-up of the pump goes to
protection due to "PFC.COM.ERR” alarm
