Configuration
Description
The bellows are completely closed, the
location of cam is set at 0 degree, and the
connection is off. The wash cycle does
not start yet.
After the power supply is connected, the
synchronous motor starts operating and
the cam begins to rotate at the same time
to open the bellows. (Location of cam is
set at 90 degrees, and the connection is
on)
After the power supply is connected and
the internal connection is turned on, the
operation continues for a while (pulse
signal) and the cam is set at 180 degrees
to start drainage. After drainage is
complete, the power supply is
reconnected from PCB to maintain the
operation for a while and turn off the
connection, which leads to close the
bellows.
