17 Faults, causes and remedies
WARNING
Have faults remedied by qualified personnel only! Observe safety in-
structions.
In the event of malfunctions occurring, the fault management system provides pump
performance and functionalities that can still be achieved.
A fault that has occurred is checked continuously if technically possible and, if possible,
emergency operation or control mode is restored.
Malfunction-free pump operation is resumed as soon as the cause of the malfunction
no longer exists. Example: The electronic module is again cooled down.
NOTICE
If the pump behaves incorrectly, check that the analogue and digital inputs are con-
figured correctly.
If the malfunction cannot be rectified, consult a specialist technician or the nearest
Wilo customer service or representative location.
