Test principle
The principle of software-assisted testing is that the SENTRON
powerconfig configuration software transmits a test signal (current
and/or voltage) to the ETU600 electronic trip unit via the USB-C
interface. The test signal is generated individually according to the
current circuit breaker protection settings and the selected test
function (LT, ST INST, N, GF, etc.).
The ETU600 treats the test signal like an actual current measured
via the current sensors and behaves as specified by the set
protection parameters. The protection function of the ETU600 is not
in test mode, nor is the protection behavior affected. This allows you
to check the real protection and system behavior and also detect
incorrect protection settings.

Test signal
The test signal corresponds one-to-one to the actually
measured signal (sample rate) coming from the analog-
to-digital converter. The test signal can be formed for
up to nine measuring inputs. The test signal is
generated individually by the SENTRON powerconfig
configuration software on the basis of the current
protection settings of the 3WA air circuit breaker and
the desired trip.

The monitoring function constantly checks the
current sensors, the analog-to-digital converter,
and the electronic components of the protection
function. Errors are detected and reported
immediately. The fault-free operation of these
components can therefore always be detected and
ensured.
The set protection parameters and their
correctness and the mechanical part of the circuit
breaker (see points (4 - 5) are not checked by the
self-monitoring function. This is where software-
assisted testing comes in, which together with self-
monitoring can test the entire functional chain.

Go to the communication cockpit
Connect the Breaker via USB-C ands select USB
as gateway

Page 10
You can make a ping to test the connection

Page 11
Go the Extended Breaker Test cockpit
The Extended Breaker Test is offline

Page 12
Go online.
Powerconfig will load the current breaker settings.
These setting are the base form the Test.

This message will come if the breaker are different
to the data in the project. Please select yes.

A Test current is selected and the Test can begin

Page 16
You have to confirm that the main contacts are
closed, if no BSS200 is available. If a BSS200 is
available, the status of the main contacts is known
and no query will appear
