Faults, causes, remedies
In order to avoid impeller/rotor blockages when the pump is at standstill for longer peri-
ods (e.g. an inactive heating system during summer), the pump regularly performs
pump kicks by briefly starting it. In this process, it starts briefly.
If the pump does not start operating within an interval of 24 hours, the system com-
pletes a pump kick. In this process, the pump must always be supplied with power. You
can change the pump kick interval at the pump.
In the "Diagnostics and measured values" menu, select
1. "Maintenance"
2. "Pump kick".
You can switch pump kicks on and off and configure the interval between 1 and
24 hours.
For more information see section 11 "Device settings – Pump kick [} 198]".
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 activated.
Flawless pump operation is only resumed once the fault cause no longer applies. Ex-
ample: The control module has once again cooled down.
Configuration warnings indicate that an incomplete or wrong configuration is prevent-
ing execution of a desired function.
The influence of faults on SSM (collective fault signal) and SBM (collective run signal)
see section "Communication interfaces: Setting and function [} 179]".
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 in-
formation and manufacturer's contact data are provided.
In the "Diagnostics and measured values" menu, select
