At one point, we defined the E-stop as the pluggable power cord.
Faster and more reliable than any other option on the market because it has two
points of disconnect.
Jerk out either end and it worked. The wall plug was the 'remote' E-stop.

Dear Brian
You are absolutely right. This is a big problem. EN 60204 is not recognized
around the world. I have just help a manufacturer to get into Canada and they
had to comply to EN 60204 for EU and IEC/EN 61010-1 for the rest of the world.
You can’t get a CB certificate for EN/IEC 60204.
I have put a big effort into finding a good way around EN 60204 but I get
caught by EU guidelines and annexes in the standards.
There must be other companies with the same problem. What do they do?
Best regards,
Mr. Kim Boll Jensen

Emne: Laboratory Equipment - the forgotten child
More trouble in the world of Laboratory Equipment (red headed step child) and
the Machinery Directive.
I’ve had TUV offices in 3 Asian countries and a customer in Australia tell us
our products (Laboratory Equipment) must have an AC Lock Out Device, an
Emergency Stop Switch, and a Light Tower because “Laboratory Equipment now
falls under the Machinery Directive”.
They are telling us that any AC product requires a lock out device. What?
On one instrument we make, the only moving part is a small dc motor with a wire
brush similar to an electric tooth brush that cleans an electrical contact
between analysis. You can stop this motor by hand without injury. This motor is
also behind a double interlock door (due to an electrical hazard), but yet they
say we must have an E-Stop switch and Light Tower.
I’m not familiar with the Light Towers. I’ve seen them on Large Production
Machines but what purpose do they serve on laboratory equipment no larger that
an upright piano? I understood they are only required to show the operational
status of a machine if not knowing the status could cause a hazard or injury.
Is there more to it? I don’t see why it would be needed if there are no
accessible hazards.
I’m getting the feeling that some believe these things are required just
because laboratory falls under the machinery directive and not for any other
reason, which seems silly to me. In the past, the machinery directive mainly
covered the safety of Production Machines which generally require these safety
components.
Can you imagine your next spectrum analyzer having an E-Stop switch because of
the cooling fan or the motorized CD drive door? Is this what it is coming to?
Why or why don’t you large powerful laboratory equipment manufacturers fight
for the official recognition of “Laboratory Equipment” and have our own
Directives, Standards, and requirements and not have to wade through all the
machinery Directive nonsense? What sense is the IEC/EN 61010-1 standard if
they are not harmonized to the MD? Why are we being forced to apply the IEC/EN
60204-1 to Laboratory Equipment where 90% of the requirements don’t or
shouldn’t apply?
Sorry for my rant. It’s been a long week. I’m just a small powerless voice
trying to sell safe products to a crazy crazy world..
