Fig. 54: List of components
An electric component is a part, assembly or device in an electrical
installation.
n
Components are marked with a combination of letters and
numbers. The identification with letters follows the standard
DIN - EN 61346 T1-T2. A component identification (BMK) e.g.:
“S04” always describes the same component. In this context
the term “component” is always considered a function specific
assignment and does not represent a parts- or article number.
This ensures that the component with the designation “S04”
always refers to the “Brake switch”, irrespective of whether the
abbreviation is used in a circuit diagram for a single drum roller,
a tandem roller, a paver or a planer.
n
The component identifications are alphabetically sorted in the
list of components. Each component has the corresponding
cross-references assigned, identifying where it can be found in
the circuit diagram, which installation location it is assigned to
and to which part of the system it belongs to. Moreover, the
functions (function text) and the technical characteristics are
also described.
Component identifications are used in both the
electrical and the hydraulic documentation and are
identical.
The overview of terminal strips contains all terminal strips used in
the machine. Each terminal strip starts on a new page and can be
localized via the cross-reference in the circuit diagram.
