9 . Installing.. Location Choose an installation point where the sensor is easily accessible for operation and service. Installation space required for the sensor unit is shown in Fig.... Mounting stand Mount the sensor either on a wall or on a metal stand. sensor's dimensions are shown in Fig. 4. Fasten the sensor securely in place so that vibration will not affect its operation. Fig. 4 shows the locations of bolt holes in the metal stand..3. Transmitter Central Unit (TCU) The TCU is always delivered with a protective shield. Choose an easily accessible location, and mount the shield on the wall with three screws. When choosing the TCU installation point, remember that the sensor cable is 0 m (~ 33 ft) long. As an option a cable of 30 m (~ 98 ft) is available. The dimensions of the shield are shown in Fig. and 3. 0 (8.66") 3 (9.3") 75,5= = = = = = (.") 6 (0.8") 600 = 6.99 Fig..

11 3. Sampling 3.. Sample lines Use flexible 3/4" FEP-tube for the sample lines between sampling point and sensor. The line must be as straight and short as possible, and it must fall steadily towards the sensor. Make sure that there are no tight bends, kinks, blockages, flat sections, or holes in the sample line. The sample flow rate must be at least 8 L/minute ( US gal/min); if necessary, use a sample pump (option) to ensure this. If the installation is made without a pump, maximum sample line length is 0 m (33 ft) and the line must have at least 7 m (3 ft) of direct fall. With sample pump (option) the sample line must be straight and its maximum length is 5 m (about 6 ft). 3..

12 3.3. Installing the sampling valves Do not install a sampler close to a pump or other device causing pressure pulses, as these will disturb the sample flow. Maximum process pressure at the installation point is 0 bar (45 psi). To obtain a representative, wellmixed sample, make sure that the sampler is sufficiently far from pipe junctions. The best sampling point is towards the end of a horizontal pipe section where the flow has stabilized. There must be a sufficient section of straight pipe (about 3 x pipe diameter) on both sides of the sampler. For installation, make a hole to the wall of the process pipe and prepare it for welding: hole diameter 6 mm ( /3"), half-v weld, dimension "a" at least equal to pipe wall thickness. Weld the sampler perpendicular to the pipe wall, so that the tip protrudes about.5 cm (") inside the pipe wall. NOTE: Shorter side of the coupling against the pulp flow! NOTE: If the pressure and flow rate are very high, a shutoff valve can be installed after the sampling valve. Installation to pipe Install sampling valve as shown in Fig. 3. Install the sample return pipe in such a way that the sample is discharged from analyzer to process. NOTE: Install the sampling valve before the pressure regulation valve! NOTE: Make sure that the sampling valve tip is below the liquid level in all situations! R3/4 min. 5 mm (") Fig. 3.

Installing a sampling valve to a channel.

13 4. Deaeration and Cleaning modules 4.. Deaeration module A deaeration module (Fig. ) can be installed to the sample line, between sampling valve and sensor. It ensures more reliable measurement results by removing gaseous air from the sample. In addition, the module contains a screen that prevents large pieces of debris from entering the sensor. Fig. shows the dimensions of the deaeration module and its mounting clamp. Install the device below the sampling point. Make sure that the cover latch on the wall side has enough room to open properly. Lead the overflow from deaeration module into a wire pit or channel. Use preferably a 3/4" sampling valve with the Deaeration module. In addition, the distance between sampling valve and Deaeration module should be as short as possible ( m, ft). The length of the sample line (diam. 3/4") from deaeration module to connection unit depends on whether or not the sensor is equipped with a pump: For a sensor with pump, the sample line between deaeration module and the inlet connection must be straight (no bends or kinking), max. length 5 m (6.4 ft), and the supply line to the pump must fall by at least 0.3 m ( ft). If the deaeration module is installed to the sample line of a sensor without pump, the line must be installed so that the direct fall is at least 7 m (3 ft). The overflow line (diam. ") to the process or to a sample discharge channel must be as short as possible. Fig. 4 shows connections of a deaeration module Fig.. Deaeration module. Fig.. Dimensions of the deaeration module. 3

14 4.. Chemical cleaning module Chemical cleaning module (Fig. 3) is used to clean the optical module and sample loop of the sensor in cases where flushing with water is not enough. Various cleaning chemicals can be used, the following are examples of some commonly used chemicals: 0% NaOH oxalic acid, max. 0% 0% citric acid and 0% formic acid in ratio : The module consists of a chemical container and a dosage pump mounted on top of it. Two container sizes are available: 0 L (5.3 US gal) and 60 L (5.9 US gal). The pump is powered and controlled by the sensor; pump control cable is connected to the electronics box connector X, terminals 9 (+) and 49(-). NOTE: Follow the safety instructions provided by the chemical manufacturer/supplier when handling and storing the chemicals! When handling the chemicals, wear appropriate protection (gloves, goggles, protective clothing, breathing mask). Fig. 3. Chemical cleaning module with 60 L chemical container.

15 5. Pump module, option 5.. Pump module functions The Metso LS sensor can be fitted with a sample pump; see section Installation. Two pump models are available (Iwaki or Schmitt), and these require somewhat different connections. Iwaki pump (Fig. ): powered from an inverter integrated in the TCU. no separate connection box. no sealing water. Schmitt pump (Fig. ): separate power connection. connection box mounted on the stand. electric connextions: see section 3 of this manual. requires a sealing water connection. Minimum sample flow rate at the outlet is 8 liters ( US gal) per minute. 5.. Sealing water connection for Schmitt pump The Iwaki pump (Fig. ) requires no sealing water. When the Schmitt pump is used (Fig. ), sealing water must always be connected and available when the pump is running. The pump will not start if it gets no sealing water, or if the water pressure is too low. The minimum pressure of sealing water: bar (9 psi), recommended flow L ( US gal) / minute. If the sealing water system tends to get clogged, increase the flow rate for example to L (0.5 US gal) / minute. Electric connections of pump: see section 3. NOTE: Before installing and starting up a sensor provided with a pump, read carefully all installation instructions, including the manual delivered with the pump. NOTE: Make sure that the pump motor type (indicated on the motor) complies with the local power network! Fig.. Metso LS with a Schmitt pump unit installed. Fig.. Metso LS with Iwaki pump. 5

17 6. Water/air module, option 6.. Function This module contains regulators and filters, attached to a mounting plate. The module ensures that the incoming water/air pressure and cleanliness meet the sensor's specifications. 86 = 7.3 a 6.. Installing R/" R/" Choose the installation point so that the connections can be made easily and the module is accessible for service. Use flexible tube for all connections. Mount the module to a wall, close to the sensor. If the sensor is mounted on a stand, you can also fasten the module behind the stand. Connect the water and air inlet lines to the module's inlet connections (R/" inside thread). NOTE: The customer is required to install shut-off valves to the water and air inlet lines. 570 =.44 R/" b 3a 4 R/" 6.3. Adjustments Water regulator adjusts the incoming water pressure (valve, Fig., part 3a). To adjust air regulator pressure, lift up the adjustment knob (Fig., part a) and rotate it. If the regulator's glass bowl contains water, open the finger nut and wait until all water has been drained out. Then screw the nut back. Check the correct pressures from Technical specifications.

21 8. Electric connections 8.. Operating voltage NOTE: Customer supplies and installs a separate safety switch to the TCU's power line. NOTE: Before connecting the mains power wires, make sure that the wires are not powered! Connect power to the wires only after you have made and checked all connections. Iwaki pump: Connect the mains power cable (00-40 VAC) to TCU through the bottom left conduit of the connection box (Fig., point ) and connect it to the terminal strip. Also connect the pump power cable from TCU to the pump. See section of this manual. Schmitt pump: Connect the mains power cable (90-60 VAC) to TCU through the bottom left conduit of the connection box (Fig., point ) and connect it to the terminal strip. Also connect the pump power cable from pump connection box to the pump. See sections & 3 of this manual. NOTE: If the TCU has been powered off for some time, the display will take some time to light up. This delay is perfectly normal, and the display will start working as soon as its internal backup battery has recharged. 8.. Sensor cable, OUL0036 In normal deliveries the sensor cable is already connected to TCU.. If the sensor cable is not connected, insert its open end (= cable end without connector) into the TCU's connection box (Fig., point ), and connect it as shown in the block diagram. Connection of protective shields: - twined shields of twisted wire pairs (wire 3) to connector GND - sensor cable shield (wire 6) to connector 'SC SHIELD' (Sensor Cable Shield). Lead the other end of the sensor cable to the sensor's connections unit, and connect it to the top connector located on the right side of the housing Current signals (4-0 ma) to mill DCS NOTE: Connect the current signal cable shields as instructed by the mill system supplier. TCU has two passive current outputs outputs (Fig., point 3). A self-diagnostics system monitors the measuring channel signal and is able to detect obvious malfunctions. When an error occurs, the diagnostics system gives an alarm and either freezes the current signal to its momentary level or forces it to a certain value, as selected by the user. Fig. shows the resistance as a function of input voltage. Resistance here means the total sum of all resistances (measurement, cables, power supply) in the current loop. HART communication requires that the resistance of the current loop is at least 50 Ohms. Ω V Fig.. Load on TCU's power supply. NOTE: Do not put the sensor cable on the same rack with power cables (motor/pump power cables etc.).

23 8.4. Electric connection of TCU with inverter (model used with Iwaki pump) NOTE: Make sure that the power supply cables are deenergized before connecting them. Check all connections before connecting power to the cables. Mounting the power connector. Remove about 40 mm from the end of the cable sheath; Fig. 3, step A. Wrap the ground conductor once around the cores before sliding on the union nut, so that the ground conductor is the last to become disconnected when extreme tension is applied.. Slide the nut onto the conductor (step B). 3. Snap the cores into the marked core entries (,,3...; steps B & C). At 30 VAC -phase power: = line = N 4 = GND At 0 VAC -phase power: = line = line 4 = GND 4. Cut off the projecting core ends so that there is no overhang (step D). Fig. 3. Mounting power cable connector. Connecting cables to TCU. Connect the power cable (Fig. 4). Push the conductor (E) onto the connector (E). Slide the nut onto the conductor (step F) and fasten it on the connector, tighten properly (3 Nm, step G).. Connect the sensor cable (Fig. ). 3. Insert the output signal cable into the TCU connector casing through the inlet and connect it to the terminal block as shown in the drawing. For voltage and resistance see Fig.. - Do not connect the protective shield of the current signal cable. 4. Insert a cable for binary inputs. Fig. 4. Connecting the power cable. 3

24 8.5. Actuator controls Metso LS has 8 binary outputs that are used to control the operation of the pump and cleaning module. These connections are made by manufacturer before shipment Binary inputs The TCU contains two galvanically isolated binary inputs. Binary inputs are used for example to transmit grade information or measuring permit (or process stop information) to the sensor. Connections in connection box terminals: BIN0 (term. 3) = grade change BIN (term. 4) = measuring permit (may be on or off, process stop means that the entire system is down) BIN GND (term. ) = binary inputs, common ground The binary inputs require - 8 VDC / 0 ma voltage. See section. Electric connections Ground connection Ground connection is not needed if the sensor setup includes a sample pump. If the sensor has no pump, the sensor cable mantle must be grounded at the sensor. Using a heavy-duty ground cable, connect the mill ground to the sensor unit with a heavy-duty ground cable. Fasten a ring clamp connector to the cable and attach it to the sensor mounting bracket under a bolt; Fig. 5. Fig. 5. Ground connection at the sensor. 4
