SENTRON powerconfig configuration software
Software-assisted testing is performed together with the SENTRON powerconfig
configuration software for Windows PCs/laptops. The individual test functions are
contained in various function packages that are activated through a license.
There are two different function packages with the following scope:
• Basic
In the basic test package, different tripping operations (LT, ST, INST, N, GF) and the
associated messages can be generated. The test results can be displayed. It is not
possible to print the test results.
The basic test package is free of charge and not limited in time.
• Standard
In the standard test package, different tripping operations (LT, ST, INST, N, GF) can
be generated and the tripping currents can be individually adjusted. The test results
can be documented in a comprehensive test report.
The standard test package is activated via a license and limited to the duration of one
year after activation.
You can purchase the function packages and the associated licenses at the Siemens
Industry Mall
(https://mall.industry.siemens.com/mall/ww/en/Catalog/Product/?mlfb=7KN2720-
0CE00-1YC1).
The licenses are managed and installed using the Automation License Manager (ALM),
see Software-assisted testing (Page 178).

Display of errors and alarms
The ETU300 and ETU600 electronic trip units have a self-monitoring and diagnostic
function.
Errors that occur are detected when the electronic trip unit is activated and displayed via
the INFO LED. The LED lights up red until the error is eliminated and the electronic trip
unit is restarted.
The color display of the ETU600 additionally shows details and an instruction for action.
Warnings are indicated by the INFO LED lighting up yellow.
Warnings due to erosion of the main contacts can be deleted from the ETU600 electronic
trip unit after an inspection or maintenance using the SENTRON powerconfig
configuration software.
