SIGMA BREWER CONTROL BOARD
This board, placed at the back of the machine, (see Fig. 32)
processes the information from the brewer unit and controls
its operation.
The board also controls the dispensing of fresh product
and the flow diverter solenoid valve from spout/external
nozzle.
The 24 V AC voltage required for board operation is
supplied by a transformer which is protected by a 800 mAT
fuse on the primary and by a 3.15 AT fuse on the secondary
winding. The voltage supply is rectified and stabilised
directly by the board.

- the green LED (8) indicates the presence of 34 V DC
variable;
- the green LED (9) indicates the presence of 34 V DC.
