[Backup System]:
Tap to turn the backup system ON/OFF
(optional), click "On"; and then click "Off" after the completion of
use.
[Backup System Type]:
Liquid Nitrogen (LN2) or Liquid Carbon Dioxide (LCO2)
[Set Injection Temperature]:
Set the temperature when the backup system starting spraying:
Liquid nitrogen (LN2), the default temperature is -70
℃
, with the adjustable range of 0 ~-100
℃
.
Carbon dioxide (LCO2), the default temperature is -70
℃
, with the adjustable range of 0 ~-70
℃
.
NOTE:
The set spraying temperature cannot to be lower than the high-temperature alarm value. If the
set spraying temperature is lower than the high-temperature alarm value, it cannot be saved.
[Project Injection Time]:
When installing a backup
system, the user can fill enter the estimated usable time of the backup system.
When needed
to confirm the remaining conditions after the backup system has been used, the user can
query its cumulative spraying time, and then judge the usage conditions of the backup system through
the difference between these two.
[
Injection Test]:
When the temperature inside the freezer does not reach the set spraying temperature, you can tap
[Injection test] to simulate the spraying conditions to confirm whether the spraying system can be
normally used. If the displayed temperature inside the freezer is greater than the set temperature, after
pressing the button of “Injection test", the displayed temperature is unchanged, and the indicator light of
backup system on the homepage is ON; at this time, control to open the solenoid valve for spraying, and
stop the spraying 10 seconds later. If he displayed temperature inside the freezer is less than the set
temperature, after pressing the button of “Injection test", the displayed temperature changes rapidly to
the set temperature; at this point, control to open the solenoid valve for spraying, and stop the spraying
10 seconds later; after that, the displayed temperature will return back to the actual temperature inside
the freezer.
