CONTROL BOARD
This board, placed at the back of the machine, (see Fig. 19)
processes the information from the push-buttons and from
the payment system, it also controls the actuations and the
push-button board.
The 15 V AC voltage required for board operation is
supplied by a transformer which is protected by a 125 mAT
fuse on the primary and by a 1.25 AT fuse on the secondary
winding. The voltage supply is rectified and stabilised
directly by the board.
The board also houses the EPROM (see Fig. 19).
- the yellow LED indicates the presence of 12 V DC;
- the green LED, when blinking indicates that the micro-
processor is working correctly;
- the red LED indicates the operating status of the boiler
heating element.
