made to the configuration settings these changes do not take effect unless the relay is rebooted.

SERVICE COMMAND
"20511" returns all settings to their factory default value. Code "101" is used to clear factory diagnostic information stored
7
in the non-volatile memory. If a code other than these two is entered, the command is ignored and no action is taken.
Various self-checking diagnostics are performed in the background while the D60 is running, and diagnostic information is
stored on the non-volatile memory from time to time based on the self-checking result. Although the diagnostic
information is cleared before the D60 is shipped from the factory, the user can want to clear the diagnostic information for
themselves under certain circumstances. For example, you clear diagnostic information after replacement of hardware.
Once the diagnostic information is cleared, all self-checking variables are reset to their initial state and diagnostics restart
from scratch.
SAVE VOLATILE DATA
recent as possible instead of relying on the periodic timer to save the data.
