Nice job dude, please keep it up
Відразу видно, що людина любить свою роботу і отримує від неї задоволення.
good nice ❤
Thanks ✌
Green and Yellow colors are not allowed for wiring inside cabinets. Geen/Yellow is for PE/EARTH wire in Europe.
Don't panic - it's GROUNDED 0VDC
5:24
It's not allowed to use metal screws inside the cable conducts. You must use plastic or nylon. NORM EN60204.
Can you please show me where in internatiol standard they are writing about this? I doubt very much that this was discussed in this standard. Another thing, the standard is constantly being updated, sometimes there are stupid requirements in it, which are then withdrawn or rephrased.
While talking about wire colors, the standard is very old and dumb: they just separated high voltage (black) from safe voltage (blue) and possible voltage when machine is powered off (orange). Also ground (G+Y). But these color standard is very old and in many situations are not helpful. Many companies produce control panels by their own wire color standards (I periodically check this while I see new machines in the factories). I have my own standard too, which is very helpful for debuging or expanding the system:
L - black, N - blue, PE - gy.
24VDC - red, 0VDC - green. 24VDC from safety device (relay or contactor) - purple. 24V signala: pnp type - white, npn type - grey.
Dry contacts (interlock) - orange.
Other control voltage levels - brown, f.e. in 5VDC system, analog voltage signal and so on...
So technically I am close to IEC standard. The different is in control (safe!) voltage part. And I am adding labels inside the control panel about the wires colors.
Не могли бы вы предоставить схему блока управления?
Hello, the drawings are useless for you - it's non standard machine + production line. There's no reason to share it 😉
@@mindaugasv85 I would just like to study it, I'm a beginner.
