A6 – Temperature-Controlled Deep Freezing and Storage
The temperature-controlled deep freezing and storage cycle is divided into the following two phases:
- Deep freezing
- Storage.
Operate as indicated to start the cycle:
1.
Make sure the device is in the
"ON"
HOME 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
HARD
key (3)
and finally press and release the key (4): 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.
5.
Press and release the START/STOP key (1): the test
to verify the correct insertion of the needle probe
will be started
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 5s every 60s and the cycle
will be started with timed-control; see "
A8 – Time-controlled deep freezing and storage
".
During deep freezing 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 stop at any time by press and release the
START/STOP
key.
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 successfully completed, the device will
automatically pass to storage and the buzzer will be
activated to indicate that the cycle ended.
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 and the
buzzer will be activated. Press and release a key to restore normal display and to silence the. 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.
