6 OPERATION
6.1 Foreword
The device can manage the following operating cycles:
- temperature-controlled blast chilling and storage
- temperature-controlled hard blast chilling and storage
- time-controlled blast chilling and storage
- time-controlled hard blast chilling and storage
- continuous blast chilling
- temperature-controlled deep freezing and storage
- temperature-controlled soft deep freezing and storage
- time-controlled deep freezing and storage
- time-controlled soft deep freezing and storage
- continuous deep freezing
For further information, see the next paragraphs
Every operating cycle can be preceded by pre-cooling; see paragraph 6.13 "Pre-cooling start-up".
The temperature-controlled cycles are preceded by a test to verify the correct insertion of the needle probe; see
paragraph 6.14 " Test for verification of the correct insertion of the needle probe".
If the needle probe is not enabled, i.e. if parameter P3 is set at 0, the temperature-controlled cycles will be started
with time-control.
The following functions can also be used:
- switching on sterilisation cycle UV light
- heating the needle probe.

6.1.1 Foreword regarding needle probe
The device can manage "multipoint" needle probes (with up to three sensors".
Parameter P3 establishes the number of needle probe sensors as indicated:
- if parameter P3 is set at 0, the needle probe will not be enabled
- if parameter P3 is set at 1, there will be one sensor (needle probe 1)
- if parameter P3 is set at 2, there will be 2 sensors (needle probe 1 and needle probe 2)
- if parameter P3 is set at 3, there will be 3 sensors (needle probe 1 and needle probe 2 and needle probe 3).
If parameter P3 is set at values different to 0, the temperature-controlled cycles will be preceded by a test to verify
the correct insertion of the needle probe; see paragraph 6.14 " Test for verification of the correct insertion of the
needle probe".
On conclusion of the test, the device will operate as indicated:
- the sensor that has detected the lowest temperature is then used as the reference temperature for heating the
needle probe.
- the sensor that has detected the highest temperature is then used as the reference for the temperature-
controlled cycles
- the sensors for which the test is not completed successfully are not used successively.
