Troubleshooting
Note
If the circuit breaker is constantly tripping during operation, first ch
eck and correct the
protection functions (parameter settings).
If problems occur that you cannot resolve yourself, Siemens will provide you with two-level
support:
● Level one:
Contact Siemens Technical Support (see Chapter Product-specific information (Page 9)).
Have the data of the circuit breaker in question at hand.
● Level two:
If the problem is not solved directly with Technical Support, a diagnostic report can be
created with the powerservice software and evaluated by Technical Support. This
requires a test device (TD410 or TD420) and the powerconfig and powerservice software.
– Load the powerconfig (https://support.industry.siemens.com/cs/ww/en/view/63452759
)
software onto a laptop computer connected to the Internet.
– Download the powerservice software from the SIOS Portal
(https://support.industry.siemens.com/cs/ww/en/view/109749079
).
– Connect the PC via the test device TD410 or TD420 to the front interface of the ETU
(see Chapter Breaker Data Adapters and test devices (Page 131)).
– With powerconfig, the parameter settings can first be checked and viewed. Incorrect
settings can be identified if necessary.
– If this does not solve the problem, the next step is to create a diagnostic report with
powerservice and send it to Technical Support.
Technical Support will evaluate the diagnostic report and connect you with a solution for
your problem.
