Conformity Discovery Process-Top things to included in your product with High Tech Design Safety

Conformity Discovery Process-Top things to included in your product with High Tech Design Safety CEO, Steve Barcik Amstel - http://hightechdesignsafety.com/ Here are the top misses that we here at High Tech Design Safety see on UL, SEMI S2 and CE marking. • Not designed to standards, including at least one electrical standard The biggest and first one is that it might not be designed to the standards that are required. So for example you are building a piece of equipment and maybe it has some moving parts in it and it’s maybe got a laser in it and of course it has an electrical section. First off, you need to include the electrical standard. Let us help you pick that…it might be 60204 or it might be 61010. It might also need to include NFPA 79. • Lack of correct over-current protection for systems/subassemblies, breakers and fuses. Use of subassemblies, with no conformity information This one is a big one that people miss on and it really causes a lot of extra time and equipment builds. • Incorrect wire types or sizes In the US typically any power circuits, anything running at line voltage, needs to be 14-gauge wire. Now you can use smaller gauges when you go to the CE standards, however the reason 14 gauge is required in North America US, is that it’s robust enough that it doesn’t get damaged while you’re building a custom piece of equipment. We will have to get in-depth with your machine specifically, but know that particular wire types have to be used with your equipment. • Grounding mission from part of system The next one is protective earth grounding and grounding missing from parts of the system. So last year… went on a field evaluation for a piece of equipment and they didn’t have the secondary neutral of a transformer grounded to the equipment that is required. • EMO/Interlock Function is inoperable, incorrect, or missing You wouldn't believe me but it's true. We will go in and push an EMO button and it won’t work or we will open a door and while they are building the machine, they jumpered out that door interlock to just make it easy. You have got to fix those before it gets inspected. And those are easy fixes. What's more difficult is, interlocks that are not there or incorrect or they’re on the drawings but they are not on machines. They are missing. All of those EMO interlocks which are safety interlocks need to be implemented using safety rated devices or parts so that they are correct. Those parts must be UL listed and CE marked… and we must be able to find that listing material. • Lack of safety warning labels and nameplates or incorrect formats or information. This is a big one…Each different standard or standard group is going to have their own type of safety labeling required. We do have a template for nameplates. Let us send it to you. • Lack of guarding I see this all the time. It's crazy. Moving equipment with moving parts needs to be guarded or it needs to be safety rated such that it can't injure someone. That guarding comes in several different types. You have fixed guarding, you have removable guarding, you got guarding with hinges and interlocks and the labeling and how they are faceted and everything is important. • Lack of required Documentation in Manuals An examples is one we were talking about just before we started this video… The labels weren’t re-created in the manuals and the warnings for hazards were not re-created in the manuals next to each process procedure service procedure, that created a hazard. So we need to be sure that you have that. • Seismic restraints needed Every piece of equipment should have seismic restraints. • Safety devices not rated for use in safety circuit Tough one. If you're using a relay for safety circuit, it needs to be a safety rated relay. Under some standards we can get around that by using a highly reliable relay… de-rating it and protecting it and everything else, but that's a whole other bag of worms and you might not get accepted. So just use a safety rated device in your safety circuit and will talk about safety PLCs and stuff like that. • Ergonomics, controls or display too high or too low Ergonomics come into play when things are too heavy to lift…when you can’t hold the door open, when the controls are too small or too large for the table, and all of those things. So wrapping this up, these are the primary top misses and non-conformance we see when someone is trying to get a listing, a SEMI S2 or CE Mark.
