13 Weighing equipment
(optional equipment)
13.1 Description
The weighing equipment comprises the following units :
• A scale unit located
• Four load cells on the frame
• Wiring.
The weight of the wash load is registered by the 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.
13.2 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.

13.4 Actual weight display
The Compas Pro control unit automatically detects if weighing equipment is connected, and the actual (current)
weight is shown on the display, on one line of the menu.
The weight shown on the display will always be the net weight (achieved because the weighing equipment has been
“tared”).
