PRINTED BOARD FUNCTIONS
AND INDICATOR LAMPS
ACTUATION BOARD
This board (see Fig. 21) activates the 230 V~ power users
by means of relays. Furthermore, it controls the signals
from the cams and/or the micro-switches on the various
power users as well as the boiler.
This board is powered with 24 VAC.
Fig. 21
The control software of the board is installed directly (via
RS232) in the microprocessor.
- the green LED (2) blinks during normal operation of the
board
- the yellow LED (6) indicates the presence of 5 V DC
- the red LED (3) glows during the board reset
- the red LED (10) indicates the operating status of the
Espresso boiler heating element
