Duration of battery-powered operation can vary from
six months to one year depending on the usage. An
audible and visual alert will be activated once battery
power is low.
Installation
(cont.)
The Cryo-Storage low level alert automatically checks
the liquid level every 30 minutes. This conserves
battery power thereby extended the security. The 25
percent level notification provides sufficient time for the
user to refill the dewar.
The user can check the level without opening the
vessel by pressing the “LEVEL CHECK” button. Re-
sults will be displayed in 30 seconds. The possible
results are provided in the following table:
ƒ MUTE: The user can mute the audible
alarm at any time by pressing the “TEST/
MUTE” button. The alarm will remain muted
until the next 30 minute check is made.
However, the LED will remain red until the
LN
2
level is raised above 25 percent.
ƒ TEST: The status light and the audible horn
can be tested by depressing the “TEST/
MUTE” button. This test can only be made
so long as an alert condition does not exist.
The remote alert circuit is activated immediatley once
a Low Battery, Low LN
2
or Sensor Fault is detected.
The remote alert will remain active even if the battery
power is depleted. Pins 1 and 2 are closed in normal
operation. Pins 2 and 3 are closed during a remote
alert condition.
