Hi folks

A comment - I would urge a little caution if IT products are being used in
the industrial or medical environments since it is these where the "traffic
light" approach is mandated in the appropriate sector standards  (e.g.
EN60204 & EN/IEC 601 respectively).

Also, "correctly" coloured LED's are now available for many purposes, so
there is not too much justification for claiming that you cannot get the
correct coloured devices!

PS: The comment is based on bitter past experience - albeit many years ago -
when working on CT Scanners for EMI Medical (now long defunct) and when
LED's were almost exclusively Red with no options!

Mark,

Clause 1.7.8.2 of EN 60950 (for ITE Equipment) states: "Where safety is
involved, colors of controls and indicators shall comply with IEC 73. Where
colors are used for functional controls or indicators, any color, including
red, is permitted provided that it is clear that safety is not involved."

We have used red LEDs in ITE equipment that is approved for use in the EU
for items such as fan faults, overtemperature faults, etc. These products
have been approved for use in the EU by both TÜV and Intertek with red LEDs.

        Is the use of Red LED's acceptable for I.T.E. equipment in the EU in
        accordance with LVD and EMCD? All comments welcome.
        Thank you.
