During storage, the 3 digit display shows the time taken to complete deep freezing successfully, the 4 digit display

shows the cabinet temperature 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.

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.

6.8

Temperature-controlled

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:

Make sure the device is in the "on" status.

Make sure that the keyboard is not locked and that no procedure is in progress.

Press and release the DEEP FREEZING key: the

LED, the

LED and the HARD LED will flash.

Press and release the HARD/SOFT key: the HARD LED will switch off.

5.1

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.

5.2

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.

5.3

Press and release the UP or DOWN key within 60 s to modify the parameter value:

Press and release the START/STOP key: the LED, 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 6.14 " 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; see paragraph 6.10

"Time-controlled soft deep freezing and storage".

Operate as indicated to stop the cycle:

Hold the START/STOP key down for 2 s.

During soft deep freezing phase, 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 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

When the temperature detected by the needle probe reaches the end temperature of the soft phase, the device

automatically passes to deep freezing.

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.
