ELECTRONIC BOARD FEATURES
The machine is equipped with 6 selectionable programs:
Program nr.
P1
P2
P3
P4, P5, P6
Each program is composed by 4 variables which can be modified (in case it is not possible to set one of them, such a
variable will obviously not appear on the display):
Variable
1. Temperature
2. Sealing
3. Shrinking
4. Shrinking delay
PHASE NR. 1 = SWITCHING THE MACHINE ON
Turn the main switch (1) into pos. 1. Before using the machine, wait until the adjusting temperature is reached. This is
signalled by the extinction of the warning light (A). The display (D) turns on and the number of the currently selected
program will appear.
PHASE NR. 2 = PROGRAMS SELECTION
Push button (P) to select the number of the program.
PHASE NR. 3 = VARIABLES PROGRAMMING
Through button (S) it is possible to look through the variables of the selected program, while through buttons (2) and (3)
the memorized values can be modified. To validate modifications, press button (S) until the number of the program
appears on the display.
The fan delay time after sealing can be modified; there is not a LED indicating this variable which is shown with an "r" on
the left display, while the right one shows the time which has been set. At the end of all variables to be adjusted, the
display will show the code of the program just chosen (for example P1).
N.B.: In case during programming the B1 limit switch is being pressed, the unit quits the scheduling, the selected
program is executed and the display shows the number of the program.
PHASE NR. 4 = PERFORMANCE
Once all adjustments have been made, the machine is ready to start working.

Machine has been switched on when the (S) button was pressed. Release the button. In case the error signalling
still persists, check the correct functioning of the button.
E 3
Working temperature hasn't been reached in the set time (10 min.). Check the correct positioning of the feeler.
Check heater and fuses. Reset through (P) button.
