4.3 Line resistances and capacitances

The detection line (D-Bus) in the interactive system can be installed using both twisted cable without shielding and with twisted shielded cable with at least 7 turns per meters. Non-shielded cable is normally preferred. The cable most frequently used has a cross-sectional area of 0.28 mm2 ... 1.5 mm2. The maximum length of line depends on the line resistance as well as line capaci-tance. The capacitance of shielded cable is greater than that for non-shielded cable so that for the same length of line a larger cross-sectional area is usually necessary to compensate. Cable manufacturers indicate the capacitance Cp’ between two lines normally. However, the relevant line capacitance for the detection line is Cs’, which is the capacitance between one line and the other line which is connected to the shield-ing (Reason: capacitive earthing of positive conductor in the D-Bus). Rule of thumb formula for the calculation of Cs’: Cp’ x 1.8 = Cs’ (100 nF x 1.8 = 180 nF).

4.4 Line resistance

The line resistance R from the detector furthest away to each of the two control unit connections must not exceed the value specified in the diagrams below.

5.3 Introduction line resistance and line capacitance

The FDnet detection line can be installed using twisted or non-twisted cables with or without shielding (recommended are twisted cables with at least 7 turns per me-ter). Non-shielded cables are generally preferred. Most of the cables used have diameters of 0.28 mm2 … 1.5 mm2. The maximum length of line (2500 m) depends on the line resistance as well as on the line capacitance.

Line capacitance Capacitance Cp’ Cp’ is the capacitance between the two wires per km. Usually the cable capaci-tance CP’ is mentioned by the cable manufacturer.

Capacitance Cs’ Cs’ is the capacitance between one wire and the other wire connected to the first one via the shield per km.

The line capacitance relevant for the detector line refers to Cs’. The reason is a possible earth fault on a detector line. The calculations (incl. calculation tool) always refer to the capacitance Cs’. For unshielded cables the following applies:

Cs’ = Cp’ For shielded cables the following applies:

Cs’ 1.8 * Cp’ (rule of thumb, if only Cp’ is known but not Cs’)

5.4 Line resistance

Supply network data for different types of cable

6 Supply network data for different types of cable

The data in the examples of types of cable shown are not binding. They have been obtained by measuring samples of cable, the origins of which are partly unknown. Before using such cable, obtain the current data from the manufacturer.

An identical cable designation by no means indicates that the cable has the same electrical parame-ters (e.g. J-Y(Yt)Y; one sample from a German manufacturer has a Cs’ value of 125 nF/km, whereas that of a Turkish manufacturer is 210 nF/km)
