System Alarms
The CryoPod Carrier has system alarms, Alarm 1 and Alarm 2, to inform the operator when the
internal basket warms. Alarm 1 is set to the colder temperature while Alarm 2 is set to a warmer
temperature. However, these alarms can be manually set to any temperature by the operator.
NOTE:
If only one alarm is enabled, then the alarm will automatically become a
TCRITICAL alarm and assigned to Alarm 2.
NOTE:
If both Alarm 1 and Alarm 2 are disabled, the "NO ALARM" indicator will be
displayed on the LCD screen.
Alarm 1: T
WARNING
Default Settings for Alarm 1
Default Alarm 1:
-155°C
Sound:
One single long beep every 30 seconds. If the sound is disabled for either alarm, both will be
disabled.
LCD Screen
: ALARM 1 appears on the LCD screen while the back light flashes red every 10
seconds.
Reset the Alarm:
The alarm will reset once the system drops to 5°C below the TWARNING level.
To Silence the audible alarm and stop the alarm back light:
Short press
and the "crossed
bell" symbol will appear on the LCD screen.
NOTE:
Unless the operator short presses button
to silence the alarm, the back
light will flash red and the sound will continue until the system reaches the TCRITICAL
level.
Alarm 1 is activated when the cryogenic chamber temperature reaches or exceeds the TWARNING
level. This alerts the operator that the LN
₂
charge is almost over and needs to be recharged. The
biospecimens should be transferred to the appropriate cryogenic storage within a few minutes to avoid
warming or the system should be recharged.
