Weighing equipment (optional equipment)Description
The weighing equipment comprises the fol-
lowing 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 convert-
er. The weight value is transmitted via a se-
rial interface to the CPU board. The weight
is then shown on the display.
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.
