What to do if Xylem Extender main protection system (fuses) is tripping?
If the main protection system (fuses) of your Xylem Extender is tripping, it could be due to a short circuit. You should check the connecting cables and the frequency converter.
Why is only one Xylem LOWARA SMB /SVE pump unit running?
If only one pump unit is running in your Xylem Extender system, it could be because the pump units have different settings. You should check the setting of the frequency converter and the serial connection between the two frequency converters.
What to do if there is demand for water but Xylem LOWARA SMB /SVE pump unit does not start?
If there is a demand for water but your Xylem Extender pump unit does not start, the setpoint may be set at zero. You should check the setting of the frequency converter and set the setpoint.
