DURING/AFTER POWER FAILURE

■

Display of chamber temperature during power failure

By depressing the buzzer stop key (BUZZER) during “power failure alarm”, the buzzer stop and the
chamber temperature is displayed on the temperature display for 5 seconds.
• Check the chamber temperature as appropriate by depressing the buzzer stop key (BUZZER) during
power failure.

<Important>

The battery for power failure alarm is a consumable part. Replace the battery about every 3 years. The
alarm would not be activated at power failure if the battery is not replaced regularly. Contact our sales
representative or agent for the replacement of battery.

■

Operation check after recovery from the power failure

The set value is memorized by nonvolatile memory.    Accordingly, the freezer resumes the operation with
setting before power failure.
When  the  freezer  is  recovered  from  power  failure  with  the  chamber  temperature  higher  than  the  preset
temperature, then the high temperature alarm is activated and the buzzer sounds and the remote alarm is
also  activated.    Please  push  the  buzzer  stop  key  (BUZZER)  to  silence  buzzer  and  take  appropriate
actions if needed.

REMOTE ALARM TERMINAL

The  alarm  is  relayed  to  a  remote  location  when  a  remote  alarm  device  (commercially  available)  is
connected to the remote alarm terminal.    Installation of a remote alarm device is recommended when the
unit is installed in an unattended location so that the operator of the unit is notified of the alarm.
■ Contact our sales representative or agent to arrange the installation of a remote alarm device.

The remote alarm terminal is installed at the back of the unit.    The alarm is outputted from this terminal.
Contact capacity is DC 30 V, 2 A.
