KRYOS
Lid Switch Setup
LID SWITCH SETUP can be accessed through the menu system of the control
(
MENU 6, 2, 2, 2). This option enables or disables the lid switch.
Manual Defog
DEFOG TIMER can be changed through the menu system of the control
(
MENU, 6, 2, 2, 1). This is the time interval that the valve is opened when the user
manually presses the defog button. The possible choices are disabled through 90
seconds.
Auto Defog
The AUTO DEFOG ( MENU, 6, 2, 2, 3) feature provides a burst of gaseous N2 to
the freezer to clear the fog when the lid is opened. This is activated through the lid
switch. If the lid switch is deactivated this feature will be disabled. The choices for
auto defog time are disabled through 90 seconds.
Quick-Chill
The QUICK-CHILL ( MENU, 6, 2, 2, 4) feature provides a burst of N
2
gas to the
freezer to lower the temperature each time the lid has been opened and then
closed. This is activated through the lid switch. If the lid switch is deactivated this
feature will be disabled. The choices for quick-chill time are disabled through 90
second purge of gaseous nitrogen.
Control By Temperature
CONTROL BY TEMP can be set through the menu system of the control
(
MENU, 6, 2, 3). By enabling this option KRYOS will control by temperature around
Thermocouple #1. The Temperature Control menu choices are only available if
Thermocouple #1 is enabled.
Temperature Control Settings
TEMP CTRL SETTINGS can be set through the menu system of the control
(
MENU, 6, 2, 3, 2, 1). The user can set the temperature that must be maintained
in the freezer around Thermocouple #1. The set-point can be set from
-180º to -100ºC.
Control Temperature
KRYOS can also provide a vapor chamber temperature control for specimens that
must be stored in a particular vapor temperature range. The temperature control
function operates in addition to the level control function. The level control always
takes precedence. If the liquid level of LN
2
is maintained between the START FILL
sensor and the STOP FILL sensor, the control attempts to maintain a selected
temperature around Thermocouple #1.
Menu Password
When the menu password is active, it is possible to review all of the control settings
without having the password. When a password is activated and the user presses the
menu key, two choices are available:
1) MENU (PASSWORD REQ)
2) CONTROL SETTINGS
