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 and the
HARD
LED will flash.
4.1
If parameter r19 is set at 0, the 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 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 15 s to modify the parameter value:
5.
Press and release the START/STOP key: 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 6.7 " 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.
During deep freezing, the display shows the residual time of the deep freezing duration and the LED is
on.
To modify the residual time, operate as indicated:
5.2.1
Press and release the UP or DOWN key again to modify the time value: the display will flash.
5.2.2
Do not operate for 4 s: the display will stop flashing and remain on permanently.
The successive parameters establish the following values:
-
parameter r2 establishes deep freezing duration
-
parameter r8 establishes the work set-point during deep freezing.
Operate as indicated to stop the cycle:
6.
Hold the START/STOP key down.
During deep freezing, the display shows the temperature detected by the needle probe and the
LED is on.
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 temperature, 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 15 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.
During storage, the display shows the temperature detected by the cabinet and the LED is on.
Parameter r11 establishes the work set-point during storage.
If the temperature detected by the needle probe does not reach the deep freezing end temperature within the
maximum deep freezing duration, deep freezing will not be completed successfully but will continue, the
LED will
flash and the buzzer will be activated.
Press and release a key to restore normal display and to silence the buzzer.
