6 OPERATION
6.1 Foreword
The devices can manage the following operating cycles:
- blast chilling and storage
- hard blast chilling and storage
- deep freezing and storage
- soft deep freezing and storage.
For further information, see the next paragraphs.
Every operating cycle can be preceded by pre-cooling; see paragraph 6.6 "Pre-cooling".
The temperature-controlled cycles are preceded by a test to verify the correct insertion of the needle probe; see
paragraph 6.7 " Test for verification of the correct insertion of the needle probe"; the time-controlled cycles are not
preceded by any test.
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 EVX805 and EVX815 models may also have the following functions:
- switching on sterilisation cycle UV light
- heating the needle probe.
For further information, see the next paragraphs.
6.2 Blast chilling and storage
The temperature-controlled blast chilling and storage cycle is divided into the following two phases:
- blast chilling
- storage
On conclusion of a phase, the device passes automatically to the next.
Operate as indicated to start the cycle:
1. Make sure the device is in the "on" status.
2. Make sure that the keyboard is not locked and that no procedure is in progress.
3. Press and release the BLAST CHILLING key: the LED and the LED will flash.
If parameter r21 has value 1, press and release the BLAST CHILLING key to start the cycle with timed-control:
the LED and the LED will flash and the LED will switch off (press and release the BLAST CHILLING
key again to start the cycle with temperature-control).
4.1 If parameter r19 is set at 0, the display will show the work set-point during blast chilling; this value can also be
set via parameter r7.
If parameter r21 has value 1 and it has been decided to start the cycle with timed-control, the display will show
the duration of time-controlled blast chilling; this value can also be set via parameter r1.
4.2 If parameter r19 is set at 1, the display will show the blast chilling end temperature; this value can also be set
via parameter r3.
If parameter r21 has value 1 and it has been decided to start the cycle with timed-control, the display will show
the duration of time-controlled blast chilling; this value can also be set via parameter r1.
4.3 Press and release the UP or DOWN key within 15 s to modify the parameter value.
5. Press and release the START/STOP key: the LED will remain permanently on and the test to verify the
correct insertion of the needle probe will be started; see paragraph 6.7 " Test for verification of the correct
insertion of the needle probe".
If parameter r21 has value 1 and it has been decided to start the cycle with timed-control, also the will
remain permanently on and the cycle will be started with timed-control.
5.1 If the test is completed successfully, the cycle will be started.
