• Function condition: indicates the stage's condition which can be Normal, Start, Trip, or
Blocked.
• Expected operating time: Expected time delay from detecting a fault to tripping the breaker.
This value can vary during a fault if an inverse curve time delay (IDMT) is used.
• Time remaining to trip: When a fault is detected this value counts down towards zero. When
zero is reached, the function will trip.
• Imeas/Iset at the moment: Displays the ratio between the measured value and the pick-up
level.
• Measured magnitude: In some functions it is possible to choose the monitored magnitude
between Peak-to-peak, TRMS, or RMS (the default is RMS; the available magnitudes depend
on the function).
• Characteristics graphs: opens graphs related to the protection function.
• Statistics: indicates the number of function starts, trips and blocks (can be cleared through
"Clear statistics"
→
"Clear").
• Measurements: displays the measurements carried out by the function.
• Active settings: displays the setting group that is currently in use and its settings (other
setting groups can be set in the "Settings" section).
While the function is activated and disabled in the
Stage activation submenu, you can disable the
function through the "Info" section ("Function mode" at the top of the section).
Figure. 4.4 - 12. Settings.
The stage settings vary depending on which protection function they are a part of. By default only one
setting group of the eight available setting groups is activated. You can enable more groups in the
Control

Setting groups menu, although they are set here in the "Settings" section.
Most protection functions follow the same structure:
• Pick-up setting: Defines the fault magnitude. Most functions pick-up value is in relation to the
current transformer or voltage transformer nominal, but some functions use kW, ohm, Hz and
other units. Voltage and current transformers nominal values can be set at

Transformers.
• Delay type and operating time delay settings are described in detail in chapter
