The LHMI is used to access the relay parameters. Three types of parameters can be read and written.
- Numerical values
- String values
- Enumerated values
Numerical values are presented either in integer or in decimal format with minimum and maximum values. Character strings can be edited character by character. Enumerated values have a predefined set of selectable values.
Note: Changing the function block on or off affects the visibility of its parameters in the menu.
Note: Changing the value of certain relay parameters affects the visibility or range of other parameters in the menu. This indicates which parameters or parameter values become obsolete due to the change. The relay changes the visibility or range of these parameters immediately even before the changed values have been committed.
Tip: Some parameters may be hidden because the function is off or the setting visibility is set to “basic” instead of “advanced”.
