SIGMA BREWER CONTROL BOARD
This board, placed at the back of the machine, (see Fig. 31)
processes the information from the brewer unit and con-
trols 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 T1.6 A
fuse on the primary and by a T3.15 A fuse on the secondary
winding. The voltage supply is rectified and stabilised
directly by the board.
- the green LED (7) indicates the presence of +5 V;
- the green LED (8) indicates the presence of 34 V DC
variable;
- the green LED (9) indicates the presence of 34 V DC.
