Brian,

I'm in a bit of a rush this evening so I can't spend as much time on this as 
perhaps it deserves, but maybe the following questions/observations will help 
to carry this forward:

Can you not perhaps issue separate Declarations for each part of the system, 
plus one over-arching Declaration for a system which consists of all the 
possible options/permutations (which deals with the Machinery Directive 
'co-ordinated machinery' aspect)?

There is no requirement for there to be a serial number, and even where there 
is, one Declaration can cover a range of serial numbers. Here is what the 
Machinery Guide says:

As a general rule, the serial number of the machinery covered by the EC
Declaration of Conformity shall be indicated. In the case of machinery
produced in large series, it is possible to draw up a single EC Declaration of
Conformity covering a range of serial numbers or batches, in which case the
range covered by the declaration must be specified and a new EC Declaration
of Conformity must be issued for each new range of serial numbers or batches.
In any case, the necessary identification must be provided to ensure the link
between each item of machinery and the EC Declaration of Conformity that
applies to it.


I think you need to consider what is practical as well as the exact letter of 
the law. It is sometimes helpful to consider this from the angle of what the 
Technical File says - if you do a separate risk assessment for every model 
built then a unique, signed, individual DofC for each unit is probably 
appropriate, but if you use a risk assessment which covers a range of models 
and serial numbers then it is probably appropriate to issue a Declaration which 
covers the same range. 

Happy to continue this correspondence privately if you wish!

Nick.
