7.5.1
– 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.

7.5.2
– 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.
