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.
4.1
Press and release the MENU key and then press and release the
key or the
key to select the blast chilling
end temperature and the work set-point during blast chilling.
4.2
Press and release the
key or the
key to modify these values and then the ESCAPE key to memorise them;
these values can also be memorised 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; see paragraph 6.14 " 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 blast chilling 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; see paragraph 6.4 "Time-controlled hard blast chilling and storage".
During hard blast chilling phase the device displays the temperature detected by the needle probe, the cabinet
temperature, the program name (if envisioned) and the time passed since the start of blast chilling .
Operate as indicated to stop the cycle:
6.
Press and hold the START/STOP key 3 s.
The successive parameters establish the following values:
-
parameter r5 establishes the maximum blast chilling duration
-
parameter r9 establishes the work set-point during the blast chilling hard phase
-
parameter r13 establishes blast chilling hard phase end temperature.
When the temperature detected by the needle probe reaches the hard blast chilling phase end temperature, the device
automatically passes to blast chilling mode.
During blast chilling the device displays the temperature detected by the needle probe, the cabinet temperature, the
program name (if envisioned) and the time passed since the start of blast chilling.
