The second phase is completed successfully if the "temperature detected by the needle probe - cabinet temperature"
difference is 1°C/1°F higher with respect to the previous control in at least 6 controls out of 8 (the controls are
performed at time intervals corresponding to 1/8 of the time established with parameter r18; consider the difference
without sign).
If the test is completed successfully, the cycle will be started; if the test is not completed successfully, the
LED
will flash and the buzzer will be activated for 5 s every 15 s.
To start the temperature-controlled cycle, press the BLAST CHILLING key or the DEEP FREEZING key. After
1 min from the signal that the test has not been completed successfully without having operated, the cycle is started
with time control.
If parameter r17 is set at 0.0, the test will not be carried out (neither first nor second phase).

Switching on UV light for sterilisation cycle
Operate as follows:
1.
Make sure that parameter u11 is set at 2.
2.
Make sure the device is in the "on" status and that the door is closed, i.e. the door micro switch is not active.
3.
Make sure that the keyboard is not locked and that no procedure is in progress.
4.
Hold the DEEP FREEZING key down for 1 s: the
AUX
LED will switch on.
The UV light is switched on for the time period established by parameter u6; opening the door i.e. the activation of the
door micro switch cause the light to switch off.
6.9
Heating the needle probe
Operate as follows:
1.
Make sure that parameter u11 is set at 1.
2.
Make sure the device is in the "on" status or storage is in progress and that the door is open, i.e. the door
micro switch is active.
3.
Make sure that the keyboard is not locked and that no procedure is in progress.
4.
Hold the DEEP FREEZING key down for 1 s: the
LED flashes and the
AUX
LED will switch on.
Output K5 is activated at maximum for the time established with parameter u6 or until the temperature detected by
the needle probe reaches that established with parameter u7; closing the door, i.e. the deactivation of the door micro
switch input causes heating to be cut-off.
The buzzer is activated for 1 s on conclusion of heating.
