Old electric schematic ( mengele mammut harvester)

Hi All,

i'm trying to read old electric schematic for a harvester and have some question regarding  symbols and their meaning.

-> What represent the symbol designated with X1 (ws)?
-> if i look at the electromagnetic valve Y2 and Y3 they booth connect to X1 pins 2 and 3 but with different wires

Thank you.

HwAoRrDk:
If I had to guess, I would say maybe the X# represent a connector? Or perhaps a terminal block? And the "ws", "bl", "rt" are colour codes? Weiss (white), blau (blue), rot (red)?

ebastler:
Agree, the Xs must be something that gets plugged in. It seems that X refers not to one of the endpoints of the connection, but the connecting element itself. Wiring harness, jumper block or such?

Ws, rt, bl are clearly colours, as decoded by HwAoRrDk. Very common to find these two-letter abbreviations in German schematics and wiring diagrams.

EDIT: Oh, there are more colour-coded lines to the left and right of each "X". Probably those lines are the wires, with the small-print colour codes (often striped colours like bl/sw = blau/schwarz) plus a number which might designate the cross section. In that case the Xs would be some connecting elements between wires.

zero0d:
thank you for the replay.

yes your are correct for some statements that you made. The Schematic is in German, here is what i know
-> eg. marked in green bl/gr 1.5 -> means wire color blau/grau ( blue/grey) and 1.5square wire cross-section
-> eg. Y2, Y3 , Y and the symbol is the marking for a electromagnetic valve with two pins (1 and 2) , pin 2 is connected to GND with braun/brown 1.5 square wire

I also thought that X1 is some kind of connector but how can the same connector have two pins numbered 2 and two pins numbered 3 , and different wires connected to same pin
An below X1 ( i think this is a designator) it says "ws" , and I'm not shore if this is color marking?

If i think more maybe it is color marking, and the numbers meaning is as following: female connector pin 2 connects to male connector pin 3  -> but i'm not shore  :)

Also marked in purple below connectors ( if X mean connector) there a different signs, does anybody know what this is?

Br,

AVGresponding:
X1 is likely a wiring loom assembly, and the pins are numbered at each end, so "2" at one end connects to "3" at the other. This also implies that particular loom assembly may be reversible.

The symbols under the connectors are "i" and "a", and "u" and "o". Since they are all at matching ends, it may be some sort of socket assembly identifier. As a non-German speaker, I'm unable to provide a guess as to what they might be abbreviations of (though I would have decoded the wire colours easily enough).


EDIT: We might glean more useful information from a picture of the full drawing...
