PRINTED BOARD FUNCTIONS
AND INDICATOR LAMPS
ACTUATION BOARD
This board, placed at the back of the machine, (see Fig. 26)
processes the information from the push-button card and
from the payment system; it also controls the actuations,
the input signals and the boiler board.
The 15 V AC voltage required for board operation is
supplied by a transformer which is protected by a T1.6 A
fuse on the primary and by a T1.25 A fuse on the secondary
winding. The voltage supply is rectified and stabilised
directly by the board.
This board houses the Flash EPROM. The control soft-
ware of the board is installed directly (via RS232 or UpKey)
in the microprocessor.
- the red LED (7) indicates the operating status of the boiler
heating element;
- the red LED (9) for resetting the CPU glows during the
board reset;
- the green LED (11) blinking indicates that the microproc-
essor is working correctly;
- the yellow LED (12) indicates the presence of 5 V DC.
