Table 1 
1.5  Menu structure 
The relay’s menu is arranged in a tabular structure. Each setting in the menu is referred to 
as a cell, and each cell in the menu may be accessed by reference to a row and column 
address. The settings are arranged so that each column contains related settings, for 
example all of the disturbance recorder settings are contained within the same column. As 
shown in Figure  6, the top row of each column contains the heading that describes the 
settings contained within that column. Movement between the columns of the menu can only 
be made at the column heading level. For a complete list of all of the menu settings, see the 
Settings chapter P74x/EN ST.
