3.12. Initializing All Settings
When the following operations are executed, all settings are initialized to the factory defaults. Only the settings are
initialized to the defaults.
The measured active energy value and operating time etc. are not initialized.
For the initializing of maximum/minimum value, refer to the section 3.11 (page 31).
(For example, if the phase wire system is changed by initializing all settings, all maximum/minimum values will be
initialized.)
To initialize all settings to the factory defaults, execute the following operation from the CANCEL screen in the setting mode.
For more information about how to get to the CANCEL screen, refer to 3.1
Setting flow
