A7 – 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.
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 key (1), press and release the
key (2) and then press and release the key (3).
The device will display the deep freezing end
temperature and the work set-point during deep-
freezing.
4. Press and release the MENU key and then press and
release the UP key or the DOWN key to select the
deep freezing end temperature and the work set-point
during deep freezing.
4.1 Press and release the (+) key or the (-) key to modify
these values and then the ESCAPE key to memories
them; these values can also be memorized through
parameters r4 and r8.
5. Press and release the START/STOP key (1): the test
to verify the correct insertion of the needle probe will
be started; "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 buzzer will be activated for 5 s every 60 s and the cycle
will be started with timed-control; "Time-controlled soft deep freezing and storage".
During the soft deep freezing phase the device displays the temperature detected by the needle probe, the
cabinet temperature, the program name (if named) and the time passed since the start of deep freezing.
6. The cycle can be stopped at any time by pressing and releasing the START/STOP key.
