13 Faults, causes, 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 functionalities.
Any occurred faults are permanently checked and, if possible, emergency operation or control mode are ac-
tivated.
Flawless pump operation is only resumed once the fault cause no longer applies. Example: The control mod-
ule has once again cooled down.
Configuration warnings indicate that an incomplete or wrong configuration is preventing execution of a de-
sired function.
NOTICE
If the pump behaves incorrectly, check that the analogue and digital inputs are configured
correctly.
The influence of faults on SSM (collective fault signal) and SBM (collective run signal) see section "Commu-
nication interfaces: Setting and function [} 153]".
13.1 Diagnostics help
In order to support fault analysis, the pump provides additional help apart from fault notifications:
Diagnostics help is used for diagnosis and maintenance of electronics and interfaces. Apart from hydraulic
and electrical overviews, information about interfaces, device information and manufacturer's contact data
are provided.
