Parameters
Plausibility check: In order to prevent obvious wrong settings the device
monitors constantly all temporarily saved parameter changes. If the device
detects an implausibility, this is indicated by a question mark in front of the
respective parameter.
In order to make things easier to follow, especially where complex
parameter changes are involved, on every superior/higher-ranking menu
level, above the temporarily saved parameters an invalidity is indicated by
the question mark (plausibility trace). This makes it possible to control or
follow from the main menu level at any time where implausibilities are
intended to be saved.
In addition to the question mark trace to the temporarily saved implausible
parameter changes a general implausibility symbol/question mark is faded-
in at the left corner of the display, and so it is possible to see from each
point of the menu tree that implausibilities have been detected by the
device.
A star/parameter change indication is always overwritten by the question
mark/implausibility symbol.
If a device detects an implausibility, it rejects saving and adopting of the
parameters.
Example: If the residual voltage has been parameterized as »calculated«
(
»EVTcon = calculated« ), then the device recognizes an implausibility in
case voltage measuring is parameterized as »phase to phase« ( »VTcon =
Phase to Phase« ). The calculation of the residual voltage is physically not
possible by means of phase-to-phase voltages.
Changing of Parameters when using the Smart View - Example
Example: Changing of a protective parameter (to alter the characteristic for the overcurrent protection function
I[1] in parameter set 1).
•
In case Smart view is not in operation – start this software.
•
In case the device data has not been loaded – select »Data To Be Received From The Device« in menu
»Device«.
•
Double-click the »Protection Para Icon« in the navigation tree.
•
Double-click the »Protection Para Set Icon« in the navigation tree.
•
Double-click the »Set 1 Icon« in the navigation tree.
•
Double-click the »protection stage I[1]« in the navigation tree.
•
In the working window a tabulated overview appears, showing the parameters assigned to this protective
function.
•
In this table double-click the value/parameter you want to change (here: »Char« ).
•
Another window (popup) is opened where you can select the required characteristic.
•
Close this window by clicking the »OK« key.
