Faults, causes and remedies
WARNING
Have faults remedied by qualified personnel only! Observe safety in-
structions.
In the event of faults, fault management only provides feasible pump outputs and

Any occurred faults are permanently checked and, if mechanically possible, emergency
operation or control mode are activated.
Flawless pump operation is only resumed once the fault cause no longer applies. Ex-
ample: The electronic module is again cooled down.
Configuration warnings indicate that an incomplete or wrong configuration is prevent-
ing execution of a desired function.

If the pump behaves incorrectly, check that the analogue and digital inputs are con-
figured correctly.
