PE2102A0 is the board that is used for the following purposes:
■ manage the oven loads (contactors, motors, solenoid valve, etc.);
■ read the measurements taken by the different sensors (temperature probes, door switch,
etc.)
■ powering the low voltage of the entire system;
■ communicate via CANBUS with the control board and possible bridge boards.

The transformer is electronic and
included in the power board. The
primary turn of the transformer is
powered at 230 VAC. The secondary
turn of the transformer translates the
230 VAC into 12 VAC. F1 fuse (size: 160
mA – 250 V, type: Fast Acting) is
between the power board and the
transformer primary turn.
When the transformer is shorted,
F1 blows to protect the circuits of
the power board. The power board
receives the low voltage from the
secondary turn of the transformer.
F2 fuse (size: 2 A – 250 V, type: Time
Delayed) is between the transformer
secondary turn and the power board. When one or more low voltage components are shorted, F2 blows to
protect the secondary turn of the transformer, see Fig. 14.
