Flow sensors with protection class IP 68 can not be opened anymore. The cables are factory
connected and labeled as follows.
4.4 Cable lengths
Interface cable: Interface cable: Interface cable: Interface cable: maximum length is 600 m.
Type B (BTS) signal cable:
Type B (BTS) signal cable: Type B (BTS) signal cable: Type B (BTS) signal cable: maximum length is 600 m.
Type A (DS) signal cable:
Type A (DS) signal cable: Type A (DS) signal cable: Type A (DS) signal cable: the maximum length depends on the conductivity of the fluid:
Field current cable: Field current cable: Field current cable: Field current cable: The cross section of the cable determines the maximum length:
Figure 4-3: Labeled cables for IP 68 versions
1 Mains power (10 = blank, 11 = blue, 12 = black)
2 Field current (7 = white, 8 = green)
3 Data interface (black wires, C = marked "1", D = marked "2", E = marked "3")
4 Electrodes (1 = blank, 2 = white, 3 = red)
CAUTION!
The maximum allowed distance between the flow sensor and the converter is determined by the
shortest cable length.
