Menu Tree
The menu tree has six branches. These branches are:
1. REPORT STATUS. Display and resetting of general status information such as targets, alarms,
recloser status, etc.
2. CONTROL. Operation of control functions such as controlling virtual switches, selection of active
setting group, etc.
3. METERING. Display of real time metering values.
4. REPORTS. Display and resetting of report information such as time and date, demand registers,
breaker duty statistics, etc.
5. PROTECTION LOGIC. Display and setting of protective function setting parameters such as
pickups, time delays, etc.
6. GENERAL SETTINGS. Display and setting of non-protective function setting parameters such as
communication, CT ratios, connections, etc.
Each screen in the menu tree is numbered in the upper left hand corner of the screen. This number
indicates the current branch and level in the menu tree structure so that you do not loose track of where
you are when you have left the top level of the menu tree. You scroll through each level of the menu tree
by using the RIGHT and LEFT scrolling keys. To go to a level of detail, you use the DOWN scrolling key.
Each time you go to a lower level in the menu tree, another number is added to the screen number
separated by a period. Figures 10-2 through 10-8 illustrate all branches in the menu tree.
