I have recently attempted to use the following recommendation from Siemens for interlocking electrical control enclosures with electronic means as per the link below. https://support.industry.siemens.com/cs/ww/en/view/109762616 We ordered the parts as listed in this link on the page and are now looking at implementing the wiring as in the same schematic example. My question regards the representation of the contacts in the schematics vs on the physical 3SE5322-0BD21 3SE5322-0SB21 switch. Why do they differ? It is my experience that schematic symbols show the position of contacts of a device in their resting/non-actuated/de-energized state. This holds true for most schematics I have worked with. For this product however, every data sheet, op manual, image (industry mall), paper insert in the product box, and even on the side sticker on the switch, the contacts are shown in the actuated and interlock-energized state. This is partially how the contacts are shown in the pdf in the link as well. The contact numbering in that doesn't even match the symbol. Can anyone shed some light on why this is so? |
