6.1
The 4 digit display will show the work set-point during blast chilling; this value can also be set via parameter r7.
6.2
Press and release the UP or DOWN key within 60 s to modify the parameter value:
7.
Press and release the START/STOP key: the LED and the LED will remain permanently on and the cycle
will be started.
Operate as indicated to stop the cycle:
8.
Hold the START/STOP key down for 2 s.
During blast chilling, the 3 digit display shows “inF” and the 4 digit display shows the cabinet cell.
Parameter r7 establishes the work set-point during blast chilling.
To display the cabinet work set-point during blast chilling, press and release the BLAST CHILLING, DEEP FREEZING or
the HARD/SOFT key; to restore the normal display, press and release the same key again or do not operate for 60 s.
6.7
Temperature-controlled deep freezing and storage
The temperature-controlled deep freezing and storage cycle is divided into the following two phases:
-
deep freezing
-
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 DEEP FREEZING key: the
LED, the
LED, the
LED and the HARD LED will flash.
4.1
If parameter r19 is set at 0, the 4 digit display will show the work set-point during deep freezing; this value can
also be set via parameter r8.
4.2
If parameter r19 is set at 1, the 3 digit display will show the deep freezing end temperature; this value can also
be set via parameter r4.
4.3
Press and release the UP or DOWN key within 60 s to modify the parameter value:
5.
Press and release the START/STOP key: the LED, the
LED, the
LED and the HARD LED will remain
permanently on and the test to verify the correct insertion of the needle probe will be started; see paragraph
6.14 " Test for verification of the correct insertion of the needle probe".
5.1
If the test is completed successfully, the cycle will be started.
The maximum deep freezing duration count is started on condition that the temperature detected by the
needle probe is below that established with parameter r15.
5.2
If the test is not completed successfully, the cycle will be started with timed-control; see paragraph 6.9
"Time-controlled deep freezing and storage".
Operate as indicated to stop the cycle:
6.
Hold the START/STOP key down for 2 s.
During deep freezing, the 3 digit display will show the temperature detected by the needle probe and the 4 digit
display shows the cabinet cell.
The successive parameters establish the following values:
-
parameter r4 establishes the deep freezing end temperature
-
parameter r6 establishes the maximum deep freezing duration
-
parameter r8 establishes the work set-point during deep freezing.
To display the cabinet work set-point during deep freezing, press and release the BLAST CHILLING, DEEP FREEZING or
the HARD/SOFT key; to restore the normal display, press and release the same key again or do not operate for 60 s.
If the temperature detected by the needle probe reaches the deep freezing end temperature within the maximum deep
freezing duration, it means that deep freezing has been completed successfully, the device will automatically pass to
storage and the buzzer will be activated for the period of time established with parameter AA.
Press and release a key to silence the buzzer.
