<< Example >> To change the setting for the operation indicator LEDs of the earth fault time-delayed and

instantaneous elements from self hold to automatic reset:

Currently used specification

(factory default setting)

Target specification

Operation indicator LEDs to be
automatically reset

None

Earth fault time-delayed and earth fault

instantaneous

Operation indicator LED hold
data

01FF 00EF

To get the operation indicator LED hold data, first give a desired value for each setting item to which a
digit number is allocated as listed in the operation indicator LED hold data setting table shown below.
This will make up a 16-digit binary code. Then, convert the binary code into a 4-digit hexadecimal code.

Note that the arrangement shown in the table below varies by model. Please refer to the instruction
manual specifically prepared for the model.
