Hi Folks
John Allen has opened my can of worms even further with
his very useful comments to my e.mail. Obviously the military/defence
situation is somewhat different as he states but maybe there is some
guidance there.
The answers to his comments are his follows:-
Our products are large Scientific instruments and the EMC, LVD
and Product liability directives apply
The standards we have applied are EN 61326-1 and EN 61010-1
Servicing would be to a Minor level although in some instances access
is required to units to carry out "conditioning procedures"
The target customer is generally a qualified Scientist but not
necessarily from an Electrical/Electronic Background.
Manuals to an appropriate level could be produced but are currently
only available to our service organisation.
My main area of difficulty lies in that we rely on the fact
that our electronic units are located behind locked doors or screwed
panels to achieve our LVD compliance.
It then seems at odds to encourage the user to undo these panels to
carry out routine service or repair tasks.
Also I am very uncomfortable on the product liability front if
someone was hurt or killed because we had suggested he opened panels
behind which were dangerous voltages.
It has been suggested that we should obtain a declaration that the
user has qualified trained staff who are capable of doing this work.
Could staff be regarded as qualified if they had not been trained by
us in the use of proprietry units? Many of our instruments go to
academic users who usually consider themselves competant in every
area. I would be interested in the groups comments in this area.
Finally as John states very specific instructions would have to be
given on reassembling units in order to maintain the units/systems
emc signature
These are the main reasons I feel these operations should only be
carried out by our own Staff. Although I can understand a customers
position when he has a piece of capital equipment worth up to stlg750k
he is unable to use due to the failure of a simple component

Brian Harlowe
