Operation during power failure

When the battery switch for power failure is ON during a power failure the following will occur:
●The power failure alarm is activated [page 47].
Press Buzzer key to silence the buzzer of the power failure alarm. In case the ring back is turned ON, the
buzzer will sound again if the power has not resumed after the ring back set time has elapsed [page 31].
●LCD touch panel is turned OFF [page 47].
By touching the LCD touch panel, it will light up for 5 seconds.
The High/Low Alarm is ready to activate during a power failure [pages 24 - 25 and 47].
●
An alarm message is displayed on the message display field. Alarm display, the buzzer and the remote alarm
as the power failure alarm are being activated.

●Operation log data and alarm log data is saved during a power failure.
Note: If the battery for power failure alarm is flat during a power failure, subsequent operation log data
and alarm log data will not be saved.

Operation after recovery from power failure

The set value is memorized by nonvolatile memory. The chamber will resume operation with settings from
before the power failure.
Note:
•It may take up to 1 minute for the LCD touch panel to light up after recovery from power failure.
•All products connected to a power source will start at the same time after recovery from a power failure.
This can cause a voltage fluctuation will could affect the starting of the unit. To prevent this situation, set
the appropriate compressor delay time of each unit [pages 25 - 26].
Although the power failure alarm will be cancelled
after recovery from a power failure, the buzzer will
continue to sound and "Alarm" will be displayed
alternately in normal characters and reverse video
in the alarm display [page 49]. By pressing the
Buzzer key, the alarm display will return to
"Normal" and the buzzer will stop.
