With the freezer properly installed and connected to power, system set
points can be entered. The following set points can be entered in Settings
mode: Control temperature, high temperature alarm set point, low
temperature alarm set point, and (optional) BUS set point. Default
settings are shown in the table below. See Chart 1-1 for more detail.
Note
If the set point is changed and the low temperature and high
temperature alarms are set 10° from the set point, the alarm set points will
be adjusted automatically to maintain a distance of at least 10° from set
point.
s
The freezer has an operating temperature range of -50°C to -86°C (-86C
units) or -10°C to -40°C (-40C units), depending on ambient
temperature. The freezer is shipped from the factory with a temperature
set point of -80°C (-86C units) or -40° (-40C units). To change the
operating temperature set point:
1. Press the Mode key until the Settings indicator lights.
2. Press the right arrow until “SET PT = -XX” is displayed in the message
center.
3. Press the up/down arrow key until the desired temperature set point is
displayed.
4. Press Enter to save the set point.
5. Press the Mode key until the Run indicator lights for Run mode or
press the right/left arrow keys to go to next/previous parameter.
If no control keys are pressed, the freezer will automatically return to RUN
mode after 5 minutes.
