ACTUATI ON BOARD
This board, placed at the back of the machine, processes the
information from the push-button card and from the payment
system
(if fitted); it also controls the actuations, the input signals
and the boiler board.
The 15 VAC voltage necessary for operating the board is supplied
by the transformer, protected by a 125 mAT fuse on the primary
winding and by a 1.25 AT fuse on the secondary winding; the
voltage is rectified and stabilised directly by the board.
This board houses the Flash EPROM. The control software of the
board is installed directly (via RS232) in the microprocessor.
The program can be updated or some of its functions can be
changed through a PC or palmtop with special Software.
- 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 microprocessor
is working correctly;
- The yellow LED (12) indicates the presence of 12 V DC.
