Entering parameters

Note
A change of parameters during operation is accepted unless the protection function affected
is in the picked-up condition (is actively metering or is above the newly set threshold value).
Software: powerconfig
powerconfig is a commissioning and maintenance software for all communication-capable
SENTRON products from Siemens. With this software, the circuit breaker can be
parameterized, commissioned and its settings can be archived and, in the operating phase,
values from the installation (current, voltage, etc.) read out and the status of the circuit
breaker can be acquired.
Setting the parameters and line frequency on the electronic trip units of the 3-series
The releases of the ETUs of the 3-series have rotary coding switches and DIP switches. The
parameters of the protection releases L, S, I, and G are set with the relevant rotary coding
switch; the neutral protection and the line frequency are set with the DIP switches.
Setting parameters with the rotary coding switch
1. Select the rotary coding switch of the protection release for which you want to set or
modify the parameters.
2. Turn the arrow of the rotary coding switch to the required parameter value using a
suitable screwdriver. The rotary switch must noticeably engage at the value and the
arrow must not point to one of the lines.
Example short-time-delayed short-circuit protection ST, parameter set I
The new parameter value is set and active.
