24 25
Please note that during power failure, the cooling system will not be
operational! - When the power returns, the appliance will return to normal
function. We highly recommend NOT to open the door during power failure,
except for moving the products to another appliance or location. An open
door will increase the temperature inside the chamber.
The appliance is equipped with a backup battery, which is able to maintain the
controllers logging feature and visual, audible and remote alarm features for
a minimum of 72 hours. By pressing the on/off button while in power failure
mode, the display will light up and show the duration of the power failure and
the current temperature for a brief moment, and then turns off again.
The compressor failure alarm cannot be set in the settings menu. It is factory
preset and will only appear in the display in case of compressor failure. The
compressor failure alarm is only applicable for appliances with dual cooling
system. The compressor failure alarm activates if a compressor operates
outside normal conditions. The activation of the compressor failure alarm will
switch off the compressor that operates abnormally and keep the other com-
pressor running. The malfunctioning compressor is deactivated to protect the
compressor from running outside normal conditions.
Important: Please note that the compressor will not be reactivated by
accepting the alarm.
Recommended actions
If it is a non-recurring alarm, the compressor can be reactivated by restarting
the appliance (switching the appliance off and on again using the ON/OFF
button). If it is a recurring alarm, please contact your local distributor for
technical support.
Description of compressor failure alarm
- Probe failure - The probe mounted in the appliance measures the
temperature of the chamber and controls the operation of the cooling system.
f the probe is disconnected or damaged, the probe failure alarm will be
activated and the cooling system will stay in operation controlled by a timer
function. If the probe errors, the temperature will show + 55°.
- Power failure - The appliance needs power to operate the cooling system.
In case of power loss, the controller will go into power failure mode and the
screen will go black. The alarm (red light) will start to flash.
Attention!
The Power failure icon will remain in the display until the alarm is accepted.
Logging interval
The controller has a built-in memory for logging the
operating data of the appliance. The controller automatically logs the data at
the set time interval. The time interval is adjustable in minutes.
Attention!
The factory log setting is one minute. To provide the best service and support Arctiko
STRONGLY recommends keeping this setting. When logging every minute, the capacity
of the memory is more than 20 years. Changes to the logging time interval will not be
activated before the device is reset. Turn the appliance OFF and then ON.
