Power Supply And Programme Selection; Beam On Floor" Function (Certain Models Only) - Electrolux DIVA 60 cm Service Manual

6.3 Power supply and programme selection

The main board is powered by the closure of
contacts 1-5 and 2-4 of the ON/OFF button
(PU). The connectors used in this case are A2
(neutral) and B1 (line).
The control/display board (user interface) is
powered at 5V by the main board, making
programme selection possible.
When the door is closed, the main board
detects the closure of the contacts of the switch
(IP) across connectors B2-D1, and starts the
washing programme. The same switch powers
the electrical components.
When the door is opened, the power loads are
disconnected from the power supply and the
cycle is paused.
6.3.1

"Beam on floor" function (certain models only)

Certain models feature a special device
(beamer) installed between the door and the
inner door and connected to terminals E6, E4
and E3 on the circuit board.
This device projects a beam of red light onto
the floor and operates in the same way as the
end-of-cycle LED:
The beam remains lit when the end of the
cycle has been reached.
The beam lights intermittently to signal an
alarm condition.
