4.0 CBW DESCRIPTION
The CBW scales have an enclosure with all components mounted within it. To gain
access to the components remove the 4 screws securing the cover to the base.
The basic unit consists of:
Base
Load Cell frame
Power switch
Main PCB assembly
Battery
Display PCB assembly
Keypad
All models of CBW are similar except the selection of load cells and the program.
The main circuit board is the same as used in the CBC scales. Normally if a problem
is found with a circuit board the most cost effective method of solving the problem is
to replace the circuit board.
Schematics are attached in order to complete the documentation. However it is rare
that the problem due to a faulty component on the PCB is traced by a user.
The main PCB assembly includes:
A/D converter (AU1),
Microprocessor (DU1) and
Power supply/battery charger circuits (DU5, T2).
