CAUSE
Mains voltage below the threshold set in P05.01.
Grid voltage above the threshold set in P05.02.
Grid frequency below the threshold set in P05.03.
Grid frequency above the threshold set in P05.04.
Grid voltage asymmetry higher than the threshold set in P05.05.
Lack of one of the phases.
Incorrect phase sequence.
The motor has not started with a current greater than 10% of the rated current in the times
defined in the M05 menu or the input programmed with the pump pressure switch function
has not closed.
Motor current higher than 500% of the rated for a time longer than 5s.
Pump runs with vacuum. Measured power factor lower than the threshold set in P05.13
The motor current is below the threshold set in P05.06.
The motor current is higher than the threshold set in P05.07.
The maximum current asymmetry threshold set in P05.14 has been exceeded.
The printed circuit board detects a current greater than 5 % of the I
influence on the motor start
One or more current transformers are not connected correctly (negative active power is
measured). Check the connections at terminals 57, 58, 59, 60
Internal error. Contact Technical Support
The pump room temperature is below the threshold set in P04.02 for longer than P04.03.
The pump room temperature is above the threshold set in P04.04 for longer than P04.05.
Alarm generated by the input programmed with the Water Reserve function.
Water level in the tank below the threshold set in P02.18.
Water level in the tank below the threshold set in P02.19.
