Information on and Process in Case of Power Failure
• The DR recorder adds ¥ to the time on a printout provided upon recovery from a power failure.
It does not print the character, however, if it has been more than 12 hours since the power
failure occurred.
• The DR recorder excludes data occurring during a power failure from its reports.
• If the DR recorder recovers from a power failure after the time to make a report, it makes a
report immediately after the recovery.
• In an application where the REPORT PRINT menu item is set to on for automatic printing, the
DR recorder prints a report only immediately after it recovers from a power failure if the power
failure time is less than 12 hours and the recorder has recovered after the preset time for report
printing.
• In an application where the REPORT PRINT menu item is set to on for automatic printing, the
DR recorder prints a report at the scheduled time for report printing if a power failure time is
less than 12 hours and the recorder has recovered before the preset time for report printing.
• If a power failure time is longer than 12 hours, the DR recorder stops report making even if the
power is restored.
The recorder prints a report (for data acquired up to the power failure), however, immediately
after it recovers from the power failure.
• If a power failure time is longer than 12 hours, the DR recorder does not print a report even if
the menu item for automatic printing is set to on. In that case, you can print a report from the
FUNC menu or send data to a communication output.
