To display the cabinet temperature, press and release the DEEP FREEZING key; to restore the normal display, press
and release the DEEP FREEZING key again or do not operate for 15 s.
When the temperature detected by the needle probe reaches the deep freezing end temperature, the device
automatically passes to storage in the same way as illustrated previously.
6.5 Soft deep freezing and storage
The temperature-controlled soft deep freezing and storage cycle is divided into the following three phases:
-
deep freezing soft phase
- 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. Press and release the HARD/SOFT key: the HARD LED will switch off.
5.1 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.
5.2 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.
5.3 Press and release the UP or DOWN key within 15 s to modify the parameter value:
6. Press and release the START/STOP key: the LED and 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".
6.1 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.
6.2 If the test is not completed successfully, the cycle will be started with timed-control.
During soft 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:
6.2.1 Press and release the UP or DOWN key again to modify the time value: the display will flash.
6.2.2 Do not operate for 4 s: the display will stop flashing and remain on permanently.
The successive parameters establish the following values:
- parameter r8 establishes the work set-point during deep freezing
- parameter r14 establishes soft deep freezing phase duration.
During deep freezing, the display shows the residual time of the deep freezing duration and the LED is
on.
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:
7.
Hold the START/STOP key down.
During soft 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 r3 establishes deep freezing soft phase end temperature.
- parameter r6 establishes the maximum deep freezing duration
- parameter r7 establishes the work set-point during the deep freezing soft phase.
