KRYOS
The Remote Alarm Timer can be set through the menu system ( MENU, 3, 3, 3). This
is the amount of time allowed to pass before the remote alarm relay is triggered if
an error condition is not corrected. The possible choices are None, Immediate, 30
minutes, 60 minutes or 2 hours.
The Lid Open Too Long Alarm can be set through the menu system ( MENU, 3, 3, 4).
This is the amount of time the lid can be open before it triggers an alarm condition.
The possible choices are None, 1, 2, 5 or 10 minutes.
The Thermocouple Alarm can be set through the menu system ( MENU, 3, 3, 5). This
alarm is activated if either thermocouple experiences an open circuit. The possible
choices are ENABLE or DISABLE.
Test Alarms
The audible, visual and remote alarms can be tested at any time by the user through
the menu system (
MENU, 3, 4). Follow the instructions on the display to hear the
audible “chirping” indicator of an alarm or to see the red LED flash or to trigger an
immediate relay closure of the remote alarm.
Logging
The on board memory logging function is one of the most powerful and useful
features of the KRYOS control. It provides a historical record for not only your freezer
but also a complete record of the environment in which specimens were stored. Four
separate logs are kept in the control:
1. System log – System logs are events that occur in the system such as lid opening/
closing, LN
2
filling Quick-Chill, Defog, etc.
2. Error log - Error logs are outside the activated preset limits detected by the
system.
3. Temperature #1 log and Temperature #2 log - The two temperature logs are simply
records of the temperatures recorded by the two thermocouples in the system.
The system and the error log each hold 4096 events while the combined
temperature logs hold an additional 32,768 temperature events. All the logs are
kept in non-volatile memory, meaning that the information is saved regardless of
whether the control has power.
When an event (system, error or temperature) occurs, the control does two things
with the data:
1. It enters the beginning or the conclusion of an event in the internal memory of
the controller.
2. It sends the event data out the serial port of the freezer.
The control consolidates the events in the internal log (combining “start event” /
”conclude event” information to provide one event with duration), however, when
the data is sent out the serial port no consolidation of data occurs.
As an example, a fill would provide one log entry in the internal log of the control,
indicated as follows:
Fill occurred on 01/07/2012 @ 8:07 for 24 minutes. The
same data coming out of the serial port would cause two entries in a computer or
printer and would be indicated as follows:
Fill Started on 01/07/12 @ 8:07
… (elapsed time)
Fill occurred on 01/07/12 @ 8:07 for 24 minutes
