[PSES] Radiated Emissions - How many points to QP?

Hello PSES brain trust, When doing radiated emissions measurements, how many frequencies should be quasi-peaked? CISPR 16-2-3 clause 6.4.9 states: "Of those disturbances above (L-20dB), where L is the limit level in logarithmic units, the disturbance levels and the frequencies of at least the

Re: [PSES] High Touch Current in Industrial Machinery

Hi Brian, Since this is machinery, typically IEC 60204-1 would be applied. Check out clause 8.2.6 Additional requirements for electrical equipment having earth leakage currents higher than 10 mA. Best regards, Mark Stultz | CMSE(r) | Sealed Air | AUTOBAG(r) brand Equipment | Streetsboro, OH

Re: [PSES] Hazard warning labels on panel doors where COTS UPS installed?

Wouldn't this fall under the requirement from 60204-1 clause 5.3.5 for Excepted Circuits? "Permanent warning label(s) shall be appropriately placed in proximity to the operating means of the supply disconnecting device to draw attention to the hazard" Best regards, Mark Stultz | CMSE(r) |

Re: [PSES] Removable door panel grounding

I love these clips for the lab and prototyping work, but check the ratings before using on any equipment in the field. In the US, most NRTLs consider this a splice which is not allowed on machinery by NFPA 79. In the EU, these parts tend to be rated only for use in structures, not equipment.

Re: [PSES] Removable door panel grounding

Hi Frank, Can you do a longer ground that allows moving the cover to the side? In my experience it is risky to design a system where the ground is routinely disconnected. If you need to design it that way, I recommend using a braided gasket that is partially compressed when the panel is

Re: [PSES] IP Code Question

Hi Brian, The IP ratings apply to continuous situations unless stated otherwise. So IPX2 means that water drops can be continuously falling at 3mm/min when the EUT is tilted up to 15°. The test lasts for 2.5 minutes per side, but the environment is considered continuous. For our machinery

Ted brings up a great point and it a good reminder that, in addition to the standards, you need a cross-functional risk analysis. This is why I always bring in a Service Tech from the field to take part in the risk analysis. They have shown me several "tool holders" over the years. Mark

Re: [PSES] Magnets as reliable fasteners

Hi Gary, I would be very cautious here. Magnetic attraction can degrade over time due to a variety of factors (thermal cycling, plating migration, corrosion, magnetic field cycling, among others). While the appliance is stationary, what about damage due to shock or vibration during shipping?

[PSES] Machinery Leakage Current

Hello, Is there a hard limit for leakage current for machinery in the EU? IEC 60204-1 provides instructions in clause 8.2.8 for "equipment having earth leakage currents higher than 10 mA". This seems quite high so we have applied the 3.5 mA limits for class 1 stationary equipment in IEC
