PRINTED BOARD FUNCTIONS
AND INDICATOR LIGHTS
ACTUATION BOARD
This board (see Fig. 25) activates, by means of relays, the
230V~ components of the machine. It controls the signals
from the cams and/or microswitches fitted on the various
users. It also controls the boiler board and the relay
boards.
This board is powered with 24 V AC.
Fig. 25
The board control software is loaded directly onto the
microprocessor (through RS232).
- Green LED (2) blinking during the normal operation of the
board
- Yellow LED (6) indicating the presence of 5 V DC
- Red LED (3) glowing during the board reset
- Red LED (10) indicating the operating status of the
Espresso boiler heating element.
