W05 : Motor current overload protection:
The circulators in the BPH-E and DPH-E series contain a current limitation system to protect the
electropumps against any current overloads.
The maximum current that can be supplied is set for each size.
If this current exceeds the set value, the protection intervenes, reducing the operating frequency (a
Warning W05 is generated in the alarm log).
If this current does not fall within the predetermined values, the pump goes into a blocking error E01 (the
fixed red "FAULT" light is lit and the alarm relay closes) and attempts to restart every 10 minutes.
