3.3 Operation instruction
Protection Set uses a unified style user interface, friendly interface. According to the
hierarchical menu mode, the prompts can be easily operated. Here is a brief introduction to
the contents of the next menu.
Main menu as below
1.R eal-time data includes measurement data and signal. When selected, the status of
the corresponding data and signal will be displayed
2.The event record shows the 32 recent events. The one displayed below the first page is the
latest event. The event record won't be lost after the device is powered off.
3. Fixed value Management including three menu:
The fixed value query and modification have the same interface. The modification interface
can modify the fixed value. The query interface cannot. After the fixed value has been
modified, retreat to fixed value management interface and select the 'fixed value setting'
menu, press the Enter key to confirm the value after input the password '000000'; Pls modify
the fixed value referring to the fixed value table.
The fixed value setting is divided into several groups according to the function. Taking
the circuit protection as an example, the following setting groups are available.
