Parameters
Device Planning Parameters
Device Planning Parameters are part of the Device Parameter Tree.
•
Improving the Usability (clearness): All protection modules that are currently not needed can be de-
protected (switched to invisible) by means of Device Planning. In Menu Device Planning you can adapt
the scope of functionality of the protective device exactly to your needs. You can improve the usability by
de-projecting all modules that are currently not needed.
•
Adapting the device to your application: For those modules that you need, determine how they
should work (e.g. directional, non-directional, <, >...).
Direct Commands
Direct Commands are part of the Device Parameter Tree but they are NOT part of the parameter file. They will
be executed directly (e.g. Resetting of a Counter).
State of the Module Inputs
Module Inputs are part of the Device Parameter Tree. The State of the Module Input is context-dependent.
By means of the Module Inputs influence can be taken on the Modules. You can assign Signals onto Module
Inputs . The state of the signals that are assigned to an input can be taken from the Status Display. Module
Inputs can be identified by an „-I“ at the end of the name.
Signals
Signals are part of the Device Parameter Tree. The state of the signal is context-dependent.
•
Signals represent the state of your installation/equipment (e.g. Position Indicators of the Circuit
Breaker).
•
Signals are assessments of the state of the grid and the equipment (System OK, Transformer failure
detected...).
•
Signals represent decisions that are taken by the device (e.g. Trip command) based on your parameter
settings.
