Weighing equipment (optional equipment)
Description
The weighing equipment comprises the
following units :
•
A scale unit located
•
Four load cells, one in each corner of the
frame
•
Wiring
The weight of the wash load is registered by
the four load cells, which send analogue
signals to the scale unit. In the scale unit the
signals are processed and converted to a
weight value in an analogue-digital
converter. The weight value is transmitted
via a serial interface to the CPU board. The
weight is then shown on the display.
Weighing the load allows the water level to
be adjusted automatically according to the
actual weight of the load, i.e. the water level
is reduced during washing if the machine
does not have a full load. The consumption
of water and energy can thus be reduced.
Safety rules
The weighing equipment is a precision
measuring device and must be treated as
such.
•
Never spray water directly onto the load
cells and scale unit.
•
The load cells are vulnerable to impact.
•
The load cells are potentially vulnerable if
welding is carried out. If welding has to
be done on the washer extractor, attach
the earth cable clamp as close as
possible to the welding site.
