4.2 Setup
The main menu “Setup” is split into two menu levels:
Level 1 is the “start menu”, it contains settings to commission the KSR1.
Level 2 is the “expert menu”, it contains the complete range of settings. This menu is protected by an additional
password.

Start menu
Password 242
To enter this menu, use the
button to select “Setup” and confirm the selection by pushing
. To enter the menu use password (242). The menus can be selected by
and
, and
entered by

This menu allows to set the natural unbalance for current or voltage of the monitored
capacitors. To store an entered value push the button
. The second line of the display
starts blinking and shows the actual measured value. To store the shown value push the
button
again. To set a new value of the natural unbalance push the
button again. The stored value of the natural
unbalance is shown in the “Info” menu. The natural unbalance is evaluated as absolute value. Thus, a drop below the
stored value is also shown and evaluated as an increase.
Here, the trip threshold is set. The threshold can be set in a range of 0,2 – 20 V for voltage and 20 mA – 5 A for current

.
It is also possible to set the threshold by a percent value, which refers to the related nominal range of current or voltage.
In factory setting, the absolute value has to be set.
Attention: This value is adapted automatically by subsequent changes of the transformer ratio.
The input can be changed to percent in menu
under

When using a VT / CT the set thresholds are multiplied by the adjusted transformer ratio.
