OPERATION: GENERAL NOTES
7.9
After entering all the necessary data, the operator can render the set melting programs operative by
proceeding as follows:
A.
Carry out the operations described in paragraph 7.3.
B. Press START-STOP (20). Set the oven start time to begin melting operations.
C.
Where the delayed start function is used the control panel displays the following:
• the yellow WAIT LED (6) comes on.
• the horizontal green segment (1) comes on.
• the set day or time appears on display (11).
• the activated program number is visible on display (14).
• the number 1 appears on display (15).
• the green HR.MIN/TIME LED (22) comes on.
If, instead, the delayed start function is not in use the control panel simultaneously displays
the following:
• the green WORK LED (7) comes on.
• a green oblique segment comes on (2.A, 3.A, 4.A or 5.A) as a function of the first work
phase setting.
• the in-chamber temperature, expressed in °C, appears on the display (11).
• the number of the program in use appears on the display (14).
• the number of the phase corresponding to the illuminated green oblique segment appears on the
display (15).
• the yellow TEMP LED (25) comes on.
• the yellow _-_-_-_- LED (26) flashes every time the in-chamber heating elements are
powered. A brief acoustic signal accompanies the above legend.
D. When the oven starts heating the temperature increase is shown on the display (11).
E.
Once the first temperature level is reached the holding (temperature stabilisation) time
begins. The display simultaneously shows the following:
• the green horizontal segment comes on as a function of the set work phase.
• the yellow LED _-_-_-_ (26) keeps on flashing.
Once the set holding time has expired, a brief acoustic signal informs the operator that the
work phase has ended and that the next one is beginning.
F.
The oven will then repeat the above-described sequence until the last temperature is
reached and the relative stabilisation time (PHASE 5) is over. Once this last holding time
has expired a buzzer sounds for 30 seconds to inform the operator that the program has
ended, after which, however, final temperature is maintained. The technician can thus
decide on the most appropriate moment in which to carry out fusion tasks.
G. Once fusion operations are over proceed as follows:
• press START-STOP (20): the word OFF appears on the display (11).
• press the main switch (16) and the oven is switched off.
