A2 – Temperature-controlled hard blast chilling & storage
The temperature-controlled hard blast chilling & storage cycle is divided into the following three phases:
- Blast chilling hard phase
- Blast chilling
- 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 key (3) and
finally press and release the key (4): the device will
display the blast chilling end temperature and the
work set-point during blast chilling.
4. Press and release the MENU key and then press and release the key UP or the key DOWN to select
the blast chilling end temperature and the work set-point during blast chilling.
4.1 Press and release the (+) key or the (-) key to modify these values and then the ESCAPE key to
memorize them; these values can also be memorized through parameters r3 and r7.
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 blast chilling duration count is started on condition that the temperature detected by
the needle probe is below that established with program 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.
During hard blast chilling 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 blast chilling.
If the temperature detected by the needle probe reaches
the blast chilling end temperature within the maximum
blast chilling duration, it means that blast chilling has
been completed successfully, the device will
automatically pass to storage and the buzzer will be
activated to indicate that the cycle has completed.
If the temperature detected by the needle probe does not
reach the blast chilling end temperature within the
maximum blast chilling duration, blast chilling will not
be completed successfully, but the system will continue
and the buzzer will be activated. Press and release any key to silence the buzzer. When the temperature
detected by the needle probe reaches the blast chilling end temperature, the device automatically passes
to storage in the same way as illustrated previously.
** The system can be stopped at any time during the cycle - press and release the START/STOP KEY
