Use of electric wiring diagrams - OV00.01-U-1901-03MAA

Wiring diagrams 

• The wiring diagrams are assigned to the familiar service information. The systems are listed alphabetically with an indication of the service information in the "Search aid for all wiring diagrams"

  OV00.01-U-1901MAA  or A3 (paper version) to facilitate finding individual wiring diagrams.

• The wiring diagrams are filed in the respective service information arranged according to the PE number,

  e.g.: PE07.61-U-2101MAA

  PE07.61-U-2101MAB

  To check the completeness of the volume the sequence of the wiring diagrams filed can be seen from the lists of contents of the respective service information. For supplements the wiring diagrams should be filed as per the supplement Specification.

  e.g.: PE07.00-U-1100MAA Overview of wiring diagrams....

• The wiring diagrams are prepared as function diagrams or control unit diagrams and are built up as follows:
  • Function diagrams

    The control units and electrical components belonging to the function are shown as symbols. The functional connections are realized by direct lines or by the data bus.

  • Control module diagrams

    Control modules are represented complete with all connected components. The feed of the control units appears first.

    The wiring diagrams also contain linkages of possible versions and functions.

    Linkages, recognizable as versions, are framed and provided with an abbreviated designation/abbreviation.

    The versions are designated with 1 and 2

• The versions identified with the abbreviated designation "U..." are listed in the legends. Explanations regarding identifications of versions with abbreviations such as ESP can be found in the section "Abbreviations for Workshop Literature".

  OV00.01-U-1001-27A  *(A4).

  The signal and circuit designations used are explained in

  "Abbreviations of signal and circuit designations for wiring diagrams" OV00.01-U-1001-28MAA  *(A5).

• Wire cross-sections may differ from that shown in the wiring diagrams.

The symbol refers to further wiring diagrams or function diagrams.

• Special features in WIS presentation

  In contrast to the presentation on paper, it is possible in the WIS to select certain areas (framed in red) and thus to jump to other documents or wiring diagrams.
