5.1 Push buttons
Push buttons are used for calling up the parameters to be processed, for selection of measuring parameters to
be indicated and for changing and storing the parameters.
The individual setting and measuring values can be selected one after another by pressing push button
<SELECT/RESET>. This push button is also used for re-setting the display by pressing approx. 3s.
As for an individual case (relay version D) the push button can also be operated when the front cover of the re-
lay is closed and sealed with lead.
Push buttons <+> <-> are used for in-/decrementing of the parameter indicated on the display. They can be
pressed step-by-step or continuously.
After the selected parameter is set by the <+> <-> push button it may be stored using the <ENTER> push but-
ton.
Through the push button <ENTER> the set value indicated on the display will be transferred to the internal pa-
rameter memory. An unintented or unauthorized change of the selected parameter is avoided by means of a
password identification (see 5.4.2).
The <TRIP>-push button is used to test the output relay circuits both for tripping and signaling. During normal
operation it is also interlocked by means of the pass-word identification.
