Layout of electric circuit diagrams

TIC Rollant 240/250 Electric System Layout of electric circuit diagrams 01... 01a / 01b ... Following the circuit diagram layout, all electric circuits are shown in individual circuit diagrams. Some explanations are given below to illustrate the layout. Numbering of circuit diagrams - The respective numbering can be found on the corresponding cover sheet and in the footer. - Depending on the machine no., the components fitted and the country specification, there may be several individual circuit diagrams for a given function.

Potentials - Main power supply (battery) - Ignition switch power supply (switched) - Relay-controlled power supply - Earth - Housing earth (external) Connections - The description provided inside the circle (e.g. “H44”) defines the connection. - Numbers next to the circle (e.g. “1b”) describe the continuation of the cabling in accordance with the circuit diagram numbering which can be taken from the cover sheet or from the footer. Designations - Connectors (e.g. „X10”, pin 2– 1– 6– 5). Each chapter lists the respective connectors and their pin assignment in the individual connection tables. - Modules (e.g.

“A23”) The arrows identify the functional inputs and outputs according to the assignment table provided in chapter ZE . - Position of components according to wiring looms +30 +15 K90/87 -31 Wiring loom A
