4. WIRING 4. WIRING • Ground the remote flowtube and the converter separately. • Cover each shield of the signal cable with vinyl tube or vinyl tape to avoid contact between two shields or between a shield and a case. • When waterproof glands or union equipped waterproof glands are used, avoid tightening the glands with an excessive torque. • In case of 24V power supply version, it comes with a plug. Use this plug to cover the unused wiring port when wiring the instrument with only one, four-core cable.
4. WIRING Finished diameter: 10.5 mm (0.413") Maximum length: 100 m (330 ft) Maximum temperature: 80°C (176°F) NOTE Conductors A and B carry the signal from the electrodes, and C is at the potential of the liquid (signal common). Shields SA and SB are kept at the same potentials as the individual electrodes (these are actively driven shields.) This is done to reduce the effect of the distributed capacitance of the cable at long cable length.
4. WIRING NOTE • For excitation and power cables, always use a crimp terminal with an insulation cover. • Use crimp tools from the manufacturer of the crimp terminal you want to use to connect the crimp terminal and cable. • Use crimp tools that are appropriate for the diameter of the cable to be connected. Washer Gasket Waterproof gland 4.3 Wiring Ports Cable This instrument is of watertight construction as stipulated in JIS C0920.
4. WIRING 4.4.2 (3) Conduit Wiring When wiring the conduits, pass the conduit through the wiring connection port, and utilize the waterproof gland to prevent water from flowing in. Place the conduit pipe on an angle as shown in Figure 4.3.4. Install a drain valve at the low end of the vertical pipe, and open the valve regularly. Terminal Configuration When the cover is removed, the connection terminals will be visible. The terminal configuration labels are attached in the locations shown in Figure 4.4.
4. WIRING 4.4.3 Precautions for Wiring of Power Supply Cables 4.4.4 DC Power Connection When using DC power as the power supply for the converter, give attention to the following points. When connecting to the power supply, observe the points below. Failure to comply with these warnings may result in an electric shock or damage to the instrument. (1) Connecting Power Supply IMPORTANT Do not connect power supply with reversed polarities.
4. WIRING 4.4.6 4.4.5 Grounding CAUTION Wiring the Remote Flowtube with the AXFA14 Converter WARNING Be sure to connect the protective grounding of the AXFA14 with a cable of 2mm2 or larger cross section in oder to avoid electrical shock to the operators and maintenance engineers and to prevent the influence of external noise. Connect the grounding wire to the mark. The grounding should satisfy Class D requirements (ground resistance, 100 or less).
4. WIRING Pulse Output (2) Connection with the Remote Flowtube (Explosion proof Type, Size 2.5 to 400 mm (0.1 to 16 in.)) In case of explosion proof type for ATEX, FM, CSA, IECEx and TIIS certification, connect wiring as shown in the figure below. IMPORTANT • As this is a transistor contact (insulated type), give attention to proper voltage and polarity when wiring. • Do not apply a voltage larger than 30V DC or a current larger than 0.2A in order to prevent damage to the instrument.
4. WIRING AXFA14 PULSE OUT AXFA14 This output cannot switch an AC load. To switch an AC load, an intermediate relay must be inserted as shown in Figure 4.4.11. *The alarm output operates from open (normal) to closed (alarm occurrence) in the default value (as setup upon plant shipment). Changes can be made via the parameter settings.
