IEC Symbols

Looking for help identifying these electrical symbols. Some are light and some are dark. What does that mean? Are they light and dark operated photo eyes? IEC Symbol.jpeg
They look like relay coils to me. The associated contacts should be elsewhere on the drawing. If it's IEC I would guess that I:2/91 is an off delay coil with a separate control and power input, the other two are something else, though from the nomneclature and geometry I'd be unsurprised if it wasn't a to a different (or in-house) standard. I would be looking for a BOM or some notes on the drawing to confirm what the components are.
