Single and Dual Input Analyzers for Low Level ConductivityAX410, AX411, AX413, AX416, AX418, AX450, AX455 & AX456 6 INSTALLATIONIM/AX4CO Issue 11 576.4.2 ConnectionsFig. 6.9 Connections, Wall-/Pipe-mount AnalyzerNote. When connecting non-metal conductivity cells or metal conductivity cells that are isolated from earth (ground), e.g.mounted in plastic pipework, link Terminal B14 (and Terminal B6 if dual input analyzer) to the earth (ground) stud on theanalyzer case - see Fig. 6.8. When connecting earthed (grounded) metal conductivity cells, ensure that the cell earth (ground) and the analyzer earth(ground) stud are at the same potential.* When a 2-wire Pt100, Pt1000 or 'balco 3k' temperature compensator is fitted.Terminal Block BConductivity Cell ConnectionsSensor B Sensor AB1 B9 Temperature Compensator Common.Link B9 to B10 (and B1 to B2 if Dual Input Analyzer) *B2 B10 Temperature Compensator Third LeadB3 B11 Temperature CompensatorB4 B12 ScreenB5 B13 Cell (Cell Electrode)B6 B14 Cell (Earth Electrode) – see Note belowB7 B15 Not UsedB8 B16 Not UsedRefer also to Section 6.6 for ABB UK and US Sensor Systems ConnectionsC1 Not usedC2 Not usedC3C4C5C6 Not usedC7 CC8 NC Relay 4C9 NOC10 CC11 NC Relay 5C12 NOC13 + Analog Output 3C14 —C15 + Analog Output 4C16 —Temperature CompensatorConnectionsB16B15B14B13B12B11B10B9B8B7B6B5B4B3B2B1TCLinkCommonTCLinkCommonTemperature CompensatorConnectionsUsed for optionalRS485 connection.Refer to IM/PROBUSBefore making any electrical connections,see Warnings on page 53Earth (Ground)Stud on Case(see Fig. 6.8.)+ 85 to 265 V ACPower Supplies 12 to 24V DC or– 24 V ACTerminal block ATerminal Block C(Option Board)Terminal Block BLine LNeutral NConnect supply earth (ground) to stud on case EC A4Relay 1 NC A5NO A6C A7Relay 2 NC A8NO A9C A10Relay 3 (see Note below) NC A11NO A12Analog Output 1 + A13— A14Analog Output 2 + A15— A16
