11 DensityPRO+ Chapter 1 Introduction Chapter 1 Introduction Description The Thermo Scientific DensityPRO+ gamma density system is designed to provide reliable, accurate process material density measurements for a wide variety of challenging applications. The gauge is mounted outside of the process vessel and never contacts the process material. The gauge can measure the density of almost any liquid, slurry, emulsion, or solution. The gauge can convert the basic density measurement into a variety of output measurements as appropriate for specific applications, e.g., bulk density or solids content per unit volume. Given a temperature input, the gauge can compensate the density measurement relative to a user-specified reference temperature. If a flow input is provided, the gauge can calculate mass flow. The setup menus guide you through the configuration process to help you quickly complete the gauge setup. The gauge has three main parts: a source, a detector, and a transmitter. The source and detector are mounted on opposite sides of the pipe or vessel containing the process material. The transmitter contains the microprocessor (CPU) board and the input/output (I/O) boards and can be mounted some distance away from the detector in a location more convenient for the user. The radioisotope source emits gamma radiation that passes through the process material. The detector measures the energy of the radiation arriving at the detector after passing through the process material (and vessel walls). The gauge determines the density of the process material by measuring the attenuation (energy reduction) of the gamma ray beam as it passes through the process material. Source Detector Transmitter Source A Cesium (Cs-137) radioisotope source is used for most applications. A Cobalt (Co-60) source is available for applications requiring a higher energy source. The radioisotope is bound in ceramic pellets and double-encapsulated in a pair of sealed stainless-steel containers. The resulting source capsule is highly resistant to vibration and mechanical shock. The source capsule is further enclosed in the source head, a lead-filled, welded steel housing. A shaped opening in the lead shielding directs the gamma radiation beam through the process material towards the detector. Outside of the beam path, the energy escaping the source head is very low and well within prescribed limits. Closing the source shutter allows the beam to be turned off (the shutter blocks the radiation) during Thermo Fisher Scientific 1-1

12 Chapter 1 Introduction DensityPRO+ installation or servicing of the gauge. All source housings meet or exceed the safety requirements of the U.S. Nuclear Regulatory Commission (NRC) and Agreement State regulations, see the Gamma Radiation Safety Manual (717904). Detector The gauge uses either an ionization chamber or scintillator type detector to measure the gamma radiation reaching the detector from the source. An ionization chamber is a sealed, temperature-stabilized chamber filled with a relatively dense gas. Radiation entering the chamber ionizes the gas, allowing current to flow between electrodes in the chamber. The detector amplifies this signal and sends it to the transmitter. The ionization chamber detector can withstand vibration and other harsh conditions. The scintillator detector consists of a special plastic scintillator material, a photomultiplier tube, and associated electronics. When radiation strikes the plastic scintillator material, small flashes of light are emitted. As the density of the process material increases, the process material absorbs more of the gamma radiation and the scintillator material generates fewer light pulses. A photomultiplier tube and the associated detector electronics convert the light pulses into electrical pulses that are sent to transmitter for processing to determine the process material density and related measurement values. The plastic scintillator used in the gauge is very efficient at converting the incident gamma radiation into light. The scintillator detector is suitable when more precision or greater sensitivity are required or when a lower-activity source must be used. Transmitter The transmitter uses the signal from the detector to calculate the process material density and related measurement values. These values can be displayed, sent to serial ports, or used to drive current outputs and alarms. The transmitter also monitors system performance and generates system fault and warning alarms. The transmitter is available in either a non-metallic (NEMA 4X) enclosure or a heavy cast aluminum (NEMA 7/NEMA 4) explosion proof enclosure. The NEMA 4X is certified (FM/CSA) for use in Division 2 hazardous locations while the NEMA 7 enclosure is certified (FM/CSA) for use in Division 1 hazardous locations. Note: Refer to the equipment tag on the gauge to verify the hazardous location certifications for your gauge. Measurement Calculation After the transmitter calculates the process material density, it can convert the data into a number of forms. For a slurry consisting of carrier and solid components, the gauge can provide measurements based on the ratio of solids to carrier. Similar measurements can be made for emulsions that consist of two different fluids and for solutions that consist of a material (the solute) dissolved in a fluid (the solvent). 1-2 Thermo Fisher Scientific

13 DensityPRO+ Chapter 1 Introduction If flow data is provided as an input, the gauge can generate mass flow measurements. The gauge can accept a 4-20 ma current input from a magnetic flow sensor or from Thermo Fisher s VersaFLO fixed or portable flow meters. For applications that require temperature compensation, the gauge can accept a temperature input to compensate the density measurement for changes in process temperature. Communications and Measurement Display Inputs and Outputs Communications with the gauge are accomplished via the integral keypad (NEMA 4X transmitter only) or via the RS-232 or RS-485 serial ports. The integral keypad on the NEMA 4X transmitter is normally used as the primary means of communication with the gauge. Menu selections, commands, and parameter values are entered using the keypad. The RS-232 or RS-485 serial ports can be used to communicate with the gauge using a remote terminal, a PC with terminal emulation software, or a Thermo Scientific HHT. Each of these options provides the functional equivalent of the NEMA 4X transmitter's integral keypad and display. Both the NEMA 4X and NEMA 7 transmitters include a four-line by 20-character display. The four-line display (20 characters per line) shows either one menu item or up to eight readouts in alternation (four at a time). The HART communication protocol is supported over the 4-20 ma current output with an optional daughter board. You communicate with the gauge using the standard Fisher Rosemount 275 HART handheld communicator. Refer to the DensityPRO+ HART Operation Manual (P/N ) for detailed instructions. The characteristics of the input and output options for the gauge are summarized in Table 1-1. The DensityPRO+ gauge provides RS-485 and RS-232 serial communication ports, a 4-20 ma current output and two contact closure inputs. The contact closure inputs can be programmed to activate any system command based on a user-provided input. System options include up to six relays, additional 4-20 ma current outputs and contact closure inputs. Thermo Fisher Scientific 1-3

15 DensityPRO+ Chapter 1 Introduction Features Dynamic Menu System Instantaneous Response Multiple Readouts Extensive Alarms The setup menus guide you through the configuration of the gauge. The Set up density, den. alarms, and flow menu group includes all of the basic parameters and commands required to quickly configure your gauge. Additional menu groups provide specialized parameters and commands allowing the gauge to be tailored to a wide variety of applications. Direct-entry menu shortcuts are also provided, allowing experienced users to access menu items and commands directly, bypassing the menu system. Our Dynamic Process Tracking (DPT) ensures that there is no lag time in the system response to significant changes in process density. When changes occur, the DPT feature reduces the normal averaging time constant by a factor of eight, ensuring a rapid, yet smooth output response. When the process stabilizes, a longer time constant is applied to reduce the fluctuations inherent in radiation-based measurements. In this way, process density changes are immediately reflected in the transmitter output, while the effects of statistical variations in the radiation measurement are greatly reduced. Select up to eight measurement values for display. Available measurement types include density, bulk density, solids concentration, carrier concentration, ratio of solids to carrier, bulk mass flow, bulk volume flow, and the rate of change of any these measurements. You can set up as many as 16 process alarms in addition to system fault alarms and warning alarms. Totalizers and Batch Control Output Signals You can set up four independent totalizers to count time, flow output, or relay signals at any rate. If your gauge has relays installed, each totalizer can close a relay (for an external counter, etc.) at user-specified count intervals. The totalizers can also close relays when particular counts are reached (for batch or sample control). You can assign any measurement to the 4-20 ma current output, or the measurement values can be sent to a remote terminal or host computer as serial data. One current output is provided on the standard I/O board. Two additional I/O boards can be provided as options with one 4-20 ma current output per board. Two relay outputs are optional on each of the I/O boards. Each I/O board also includes two contact closure inputs that can be used to activate any system command based on a user-provided input (open or close). Thermo Fisher Scientific 1-5

21 DensityPRO+ Chapter 2 Hardware Installation Mounting the Transmitter Selecting a good location to mount the transmitter can ensure the accuracy and ease of operation of your gauge. The operating temperature range is 40º C to 60º C ( 40º F to 140º F). Mount the transmitter so that the display can be easily seen and the keypad (on the NEMA 4 transmitter) is in easy reach. Do not mount the transmitter near high voltage, high current, corrosive vapors, corrosive liquids, or corrosive esters. Dimensional Drawings Refer to the proper dimensional drawing for the transmitter mounting dimensions. See Drawing for the NEMA 4X non-metallic enclosure suitable for Div. 2 hazardous locations and ordinary locations. See Drawing for the NEMA 7/NEMA 4 explosion proof enclosure suitable for Div. 1 hazardous locations. Transmitter Mounting Instructions Mount the transmitter with both four screws, or four nuts, four bolts, and eight washers. Place one screw through each of the four holes in the transmitter enclosure s flange and tighten the screws, or Place one bolt through each of the four holes in the transmitter enclosure s flange, with one washer on each side, screw on the nuts, and tighten the bolts. Mounting the Gauge Head (source and detector) Mounting Configurations The optimum gauge mounting configuration depends on the application; however, the source head and the detector are typically mounted together on the opposite sides of a pipe. The following mounting options are supported for the gauge: Chain mount Single chain (unichain) Dual chain Cradle-type (saddle) clamp Pipe spool with gauge head pre-installed Z-pipe (axial) mount for small diameter pipes The chain mount is the most frequently used mounting configuration this allows the unit to be mounted on a range of pipe sizes using the same mounting hardware. Note: Moving the gauge to a pipe with a different diameter may require changing the radiation source size and/or reconfiguring the detector (ion chamber) electronics. Call Thermo Fisher for assistance. Thermo Fisher Scientific 2-3

22 Chapter 2 Hardware Installation DensityPRO+ Guidelines for Mounting the Gauge Head The operating temperature range is 30º C to 60º C ( 20º F to 140º F) for both the scintillator and ion chamber detector types. Make sure there is enough clearance to install and service the gauge head. (Refer to the appropriate drawings for your type of gauge and mount.) Mount the source housing so the radioactive source identification tag is visible and upright. Avoid locations where process overflow, debris, or other material can collect in the beam path (especially in the source shutter mechanism). Whichever mounting configuration is used, it is important to align the beam path (the centerline of the source housing) as closely as possible with the centerline of the detector housing. Be sure to mount the gauge head securely, since any movement or change in alignment can affect the gauge s calibration. For best performance the beam must pass through a representative cross-section of the process material being measured. It is best to mount the gauge head on a vertical section of pipe. This keeps suspended solids from settling out of the measured area. (The gauge measures only the material that passes through the beam.) To mount the gauge head on a horizontal pipe Position the beam path at a 30 to 45 degree angle from vertical. This position tends to average density variations caused by settling, while reducing the effect of any trapped gases or solids that accumulate in the top or bottom of the pipe. If the process material is a solution, a light slurry, or a single-phase liquid that will not separate, the gauge head can be mounted such that the beam is horizontal. If the process material is a slurry, position the gauge head as far as possible from any elbows, tees, or valves these tend to separate suspended solids. Position the beam path in the plane of the upstream elbow so the measurement includes any uneven distribution caused by the fitting.

23 DensityPRO+ Chapter 2 Hardware Installation Gauge Head Mounting Instructions The following sections provide installation details for the various mounting configurations. Caution: Use proper lifting procedures during installation to avoid injury. Do not over-tighten the bolts. Refer to the following drawings for detector dimensions. Drawing Model 9719B scintillation detector (NEMA 4 housing) Drawing Model 9720B scintillation detector (explosion proof housing) Drawing Model 9701 ion chamber detector (NEMA 4 housing) Drawing Model 9701 ion chamber detector (explosion proof housing) Single Chain (unichain) Mounting Instructions The single chain, or unichain mount is only available with the Model 5211 source housing and the scintillation detector. In this mounting configuration, a mounting chain is inserted through an eye bolt in the rear of the source housing. The two ends of the chain are wrapped around the pipe and engaged in slotted tabs in the detector housing. The following steps describe the installation of the gauge head using a single chain mount. Also refer to the following drawings for mounting details. Drawing Model 9719B detector (NEMA 4 housing), or Drawing Model 9720B detector (explosion proof housing). The mounting hardware kit shipped with the gauge should include: Note: 1 Eyebolt ( x 3 in.), 1 Nut ( ), 1 Belleville Washer 1 Chain 1. Insert the eye bolt through hole in rear of source housing. Place Belleville washer, cupped-side first, onto the eyebolt. Thread the nut on the eyebolt until the bolt just begins to come through the nut. 2. Insert the chain through the eyebolt so that approximately the same length of chain extends on each side of the eyebolt. 3. Position the source housing and detector housing so that the V-shaped mounting features center the housings on the pipe. 4. With the axis of the source housing and detector housings aligned, attach one end of the chain in the slotted tab on one side of the detector housing. Pull the chain tight on the other side and attach it into the slotted tab on the other side of the detector housing. There must be an even number of chain links between the slotted tabs so that there will be an equal number of links on both sides. 5. Maintain alignment of the housings and tighten the nut on the eyebolt ~1/2 turn past point where Belleville washer becomes fully flattened. Thermo Fisher Scientific 2-5

24 Chapter 2 Hardware Installation DensityPRO+ Dual Chain Mounting Instructions In the dual chain mount, two mounting chains are wrapped around the pipe with their ends engaging keyhole-shaped openings in the source head mounting plate. The detector housing is then clamped to the two chains center links (opposite the source mounting plate) by tensioning bolt assemblies as illustrated in the photograph below. Details of the chain mount depend on the detector type (ionization chamber or scintillator), but the installation is similar for both types. Refer to the following drawings for mounting details. Drawing Model 9719B Scintillation Detector Drawing Model 9720B Scintillation Detector Drawing Model 9701/9702 Ion Chamber Detector The following steps describe the installation of the gauge head using a dual chain mount. 1. For either detector type, use the table on page 2-8 to determine the number of chain links to thread through the keyhole slots. Count the links and mark the links that will be engaged at each end of the two chains (four links in all). 2. For Model 9701/9702 ionization chamber detectors, partially assemble the two tensioning bolts (hardware kit ) in the following order: 1 tensioning bolt (large) 1 flat washer (onto bolt next to bolt head) 1 spacer ring 2 Belleville washer (with concave sides together) 1 special nut - thread nut securely onto the bolt end 3. For Model 9719B/9720B scintillation detectors, partially assemble the two tensioning bolts (hardware kit ) in the following order: 1 tensioning bolt (large) 1 chain - place center ring of chain over the bolt head 1 bar nut - position the guard tube towards the bolt head 2-6 Thermo Fisher Scientific

25 DensityPRO+ Chapter 2 Hardware Installation Note: 1 special nut - thread nut securely onto the bolt end. After the special nut is fully threaded, thread the bar nut back down the bolt so that it rests against the special nut 4. From the pipe side of the source mounting plate, thread one end of a chain through the plate s top keyhole opening until you reach one of the four end links you marked in Step 1. Engage this link by sliding it into one of the keyhole slots. 5. Thread one end of the other chain through the bottom keyhole and engage the marked link as you did with the top chain. 6. Position the source housing mounting plate on the pipe. If necessary, use a lift, hoist, or other means to hold it in position. 7. Pass the center part of the upper and lower chains around the pipe and thread their ends through the corresponding keyholes. Engage the marked links in the empty slots. All four chain ends must engage at the same link. If you make an adjustment, adjust all four chain ends by the same amount. Also make sure there are no twists in the chain as you wrap it around the pipe. Otherwise the gauge head will not be aligned correctly. You might have to adjust chain links (thread more or fewer links through each slot) to allow for pipe size tolerance, insulation, and so forth. Start with about 10 cm (4 inches) of play. 8. Position the detector on the pipe, opposite the source mounting plate. If necessary, use a lift, hoist, or other means to hold it in position. 9. To secure the detector and the source head mounting plate on the pipe: Position the upper chain (including the tensioning bolt assembled in Step 1) over the detector s top mounting arm. Place a spacer ring and then two Belleville washers (concave sides together) onto the pilot end of the special nut. Insert the pilot end of the chain tensioning bolt into the hole in the top detector mounting arm and tighten the chain tensioning bolt finger-tight. Repeat the previous three steps for the lower chain. 10. Alternately and uniformly tighten the chain tensioning bolts until the spacers are just touching the mounting arms. 11. Place the loose ends of the upper chain over the top edge of the source mounting plate so they won t interfere with the source housing installation. 12. Position the source housing so its four mounting holes engage the four studs on the mounting plate. If necessary, use a lift, hoist, or other means to hold it in position. 13. Use the provided lock washers and nuts to secure the source housing. Thermo Fisher Scientific 2-7

27 DensityPRO+ Chapter 2 Hardware Installation Refer to drawing 85726N and use the following steps to install a gauge head with a pipe saddle mount: 1. Assemble the two halves of the saddle mount onto the process pipe using the supplied nuts, bolts, and washers. Do not tighten the nuts and bolts yet, just thread them together. 2. Adjust the saddle mount halves so the mounting plates are parallel and even with each other. Then tighten the bolts evenly so the clamp ends are the same distance apart on both sides of the pipe. 3. Bolt the detector and source housings to the mounting plates on either side of the pipe saddle. 4. Tighten all bolts securely so the gauge head components cannot shift positions. Pipe Spool Mounting Instructions A pipe spool is normally a 30-inch section of pipe with either mounting plates or a complete gauge head already installed. Often, the customer sends a length of the required pipe to Thermo Fisher to be converted into a pipe spool mount. Warning: Use correct pipe fitting techniques suitable for the pipe being used and the process material that the pipe will handle. Use the following steps to install a gauge head with a pipe spool mount: 1. Assemble the pipe spool into the existing pipe. 2. Position the source housing so its identification tag is upright. 3. If the detector and source housings are not already installed, bolt them to the mounting plates on either side of the pipe saddle. 4. Tighten all bolts securely. Z-Pipe (axial) Mounting Instructions A Z-pipe mount is used for small pipes, four inches in diameter or less. It uses a Z-shaped pipe section so the gamma rays can travel along the pipe s axis for several inches. This lets the beam pass through more process material so the material s density can be measured more reliably. Depending on the application, the user typically fabricates the Z-pipe section and then either assembles it into the mounting fixture or sends it to Thermo Fisher for assembly. Fabricating and Assembling the Z-Pipe To fabricate the Z-pipe, refer to the drawings for your specific application. Drawing Z Pipe Fabrication Details (1-3 in. pipe sizes) Drawing Z Pipe Fabrication Details (4 in. pipe) Carefully note the tolerances for each dimension. Any variation in the Z-pipe dimensions, especially in the bracket placement, can lead to misalignment causing inaccurate readings or no readings at all. Thermo Fisher Scientific 2-9

28 Chapter 2 Hardware Installation DensityPRO+ Z-Pipe Installation Refer to the following drawings for mounting dimensions. Drawing Z Pipe Mount (1-3 in. pipe sizes) Drawing Z Pipe Mount (4 in. pipe) Caution: If a lead doughnut is provided with the mounting assembly, make sure its inside diameter matches the pipe s outside diameter. While assembling the mount, clamp the doughnut to the axial portion of the Z-pipe (between the source and detector) as close to the center as possible. Warning: If the process pipe is not strong enough to support the gauge head and mounting assembly, you must provide additional support for the gauge head. After the pipe and mount are assembled, you can install the gauge head using the steps in Pipe Spool Mounting Instructions on page 2-9, with the following additional notes: If your gauge is supplied with a large lead plate with a one- to two-inch hole in the center, the plate should be mounted between the detector and the mounting plate. If your gauge is supplied with a thin steel plate with a small lead disk, the plate should be mounted between the source housing and the mounting plate, with the disk towards the pipe (the disk should fit in the hole in the mounting plate) Thermo Fisher Scientific

36 Chapter 3 Wiring Procedures DensityPRO+ Insert the wires and make connections as shown in the appropriate installation wiring drawing. Tighten the screws in the connector to secure the wires. Plug the screw-terminal connector back into the corresponding on-board connector. 5. When all connections are complete, close and secure the transmitter cover. Caution: CSA certified fittings must be used to maintain CSA rating for enclosure. Detector-Transmitter Wiring All signals from the detector are wired to the VPI board that is installed in the transmitter slot PCB 4. Refer to the appropriate installation wiring drawings for the detailed requirements. Caution: Remove power from the transmitter before changing jumper settings. Failure to do so may result in damage to the VPI board. For the scintillator detector, the reference and data pulse lines are wired to pins 15 and 16 and 17 and 18, respectively, of connector J1B of PCB 4. The HV increase and decrease pulse cables are wired to pins 19 and 20 and 22 and 23, respectively, of connector J1B of PCB 4. For the ion chamber detector, the signal cable from the detector is wired to pins 8(+) and 9(-) of connector J1A of PCB 4. The temperature compensation input is wired to connector J1A of PCB 4. The connections depend on the type of temperature compensation input. The transmitter is used in duty cycle mode unless it is wired to a D series scintillation detector. The duty cycle mode is set by connecting jumper p3 pin 1&2 on the scintillation adapter board and shorting JP3 on the VPI board Flow Input Current Output There is also provision on the VPI board for a user-provided 4-20 ma flow input (pins 6/7 of connector J1A on PCB 4). Refer to the DensityPRO+ Operation Manual (717819) for details on how to configure the gauge to use the flow input signal. One current output (I/O) board is supplied standard, installed in the PCB 1 slot. One or two additional I/O boards can be installed as options in the PCB 2 and PCB 3 slots. The current output is programmable between 0 and 20 ma. The minimum output in the self-powered configurations is ~0.4 ma. The minimum output current in the looppowered configuration is ~3 ma. The maximum load is 800 ohms. 3-8 Thermo Fisher Scientific

37 DensityPRO+ Chapter 3 Wiring Procedures The current output is normally shipped from the factory configured as an isolated, selfpowered output. The current output can be reconfigured as isolated loop-powered by removing the jumper from pins 3 & 4 on the J5 connector on the I/O board. In the looppowered configuration, the user must supply +24 Vdc loop power to pin 3 of J5. Pin 2 of J5 is Iout+. Relays Two or four relays are available as options on the I/O board in PCB 1 slot. Refer to the installation wiring drawing (and the label inside the transmitter cover) for wiring details. Relay contacts are Form C SPDT, isolated 8 A, and 220 Vac. Contact Closure (Switch) Inputs Serial Communications RS-485 Wiring Two (user-provided) contact closure inputs are included on each I/O board. The contact closure inputs are dry contact inputs between ground and Switch 1 and ground and Switch 2. The gauge can be configured via software settings to execute a command or other function upon a user-provided contact opening or closing. Refer to the DensityPRO+ Operation Manual (717819) for instructions for assigning commands to the contact closure inputs. The gauge provides both an RS-232 single-drop and an RS-485 multi-drop serial interface. Screw-terminal connectors for both ports are located on the CPU board. The non-metallic, NEMA 4X transmitter includes both a display and a keypad that are typically used as the primary means of communication with the gauge. The explosion proof cast aluminum transmitter does not have a display; therefore, the RS-232 or the RS-485 serial port must be used to communicate with the gauge. The RS-485 connector includes the +8 Vdc required to power the Thermo Scientific HHT as well as the +Data and Data connections. An RJ-11 (phone jack) connector is also provided for the RS-485 port. The HHT can be connected directly to the RJ-11 connector. Both the RS-232 and RS-485 ports provide independent access to the measurement readings and software functions. Both ports are always active and can be used to display measurements. The setup menus, however, can only be accessed by one port at a time. To connect the serial (COM) port on a PC to the RS-485 port on the gauge requires an RS-485-to-RS-232 converter (P/N ). Connect +Data and Data on the Model 1400A transmitter RS-485 connector (located on the CPU board) to the corresponding connections on the RS-485-to- RS-232 converter. Connect the RS-485-to-RS-232 converter to the PC using a standard DB-9 serial cable. Refer to the RS-485 installation wiring drawing (868519) and the Model 1400A transmitter wiring drawings (868515, ). Thermo Fisher Scientific 3-9

38 Chapter 3 Wiring Procedures DensityPRO+ Note: Party-line Communications Initial Setup! To communicate with multiple gauges via an RS-485 party-line, each unit must be assigned a unique unit identification number so it can be addressed individually. All gauges are assigned unit number 0 (zero) by default. To assign a unique unit number to each gauge, you must disconnect each gauge from the party-line in turn and then communicate with the disconnected gauge directly. Alternately, you must remove power from all gauges except one, then assign a unit number to the single powered gauge. Repeat this procedure for the remaining gauges. CPU Board RS-485 Termination RS-232 Wiring Note: If you have trouble using another device on the RS-485 chain, verify that it is properly terminated for its position on the chain. To terminate a device, connect a 120 resistor between its RS-485 +/ data terminals. Never terminate more than the first and last device in the chain. The Model 1400A transmitter includes a three-pin header (W4), located near the bottomfront edge of the CPU board next to the RS-485 connector (J6), to terminate the RS-485 connection. For a single unit installation or for a multiple unit installation where the transmitter is the last unit in line, the W4 jumper should be placed on pins 1 and 2 to terminate the RS-485 line. For a multiple unit installation where the transmitter is the not last unit in line, the W4 jumper should be placed on pins 2 and 3 so that the RS-485 line is not terminated at the transmitter. Refer to the Model 1400A transmitter wiring drawings (868515, ) for RS-232 wiring details. The serial port on a PC (COM1 or COM2) can be connected directly to the RS-232 port on the gauge. This requires five wires ground, transmit (TX), receive (RX), RTS and CTS. The connections between the DensityPRO+ RS-232 port connector (located on the CPU board in the Model 1400A transmitter) and the PC serial port are summarized in the table below for standard DB-9 and DB-25 PC serial port connectors. CPU Board (J8) RS-232 Connector PC Serial Port DB-9 Connector PC Serial Port DB-25 Connector J8-Pin 1 (RTS) Pin 8 Pin 5 J8-Pin 2 (TX) Pin 2 Pin 3 J8-Pin 3 (CTS) Pin 7 Pin 4 J8-Pin 4 (RX) Pin 3 Pin 2 J8-Pin 5 (GND) Pin 5 Pin Thermo Fisher Scientific

39 DensityPRO+ Chapter 3 Wiring Procedures Using Serial Communications To communicate with the DensityPRO+ gauge from a PC requires that the PC be running TMTComm for Windows communications software, or other terminal emulation software. The default communication settings for the RS-232 and RS-485 ports of the DensityPRO+ gauge and for the Thermo Scientific HHT are: 7 data bits, even parity, 1 stop bit, and 9600 baud data rate. HART Communications Refer to the DensityPRO+ Operation manual for additional details about setting up and using serial communications. The HART communication protocol is supported over the 4-20 ma current output with an optional daughter board. You communicate with the gauge using the standard Fisher Rosemount 275 HART handheld communicator. Refer to the DensityPRO+ HART Operation Manual (717816) for detailed instructions.

42 Chapter 4 Troubleshooting and Maintenance DensityPRO+ Transmitter DANGER: Remove all power from the unit before opening the transmitter enclosure for servicing. Electrocution can result if power is present. Caution: Avoid mounting the transmitter in direct sunlight. Caution: Store uninstalled transmitter in a facility that maintains the ambient temperature between -30 C and +80 C. No Display When power is applied, the gauge continuously sends the measurement readouts or a setup message to the remote terminal or HHT via the serial ports, except when you access the setup menus. If the display appears to be blank after supplying power to the gauge, it is likely that the display contrast is not set properly. If the display appears to be washed out, that is, if the display characters can be seen faintly or if the display appears to be a solid yellowgreen color, the contrast needs to be increased. If the display appears to consist of dark rectangles (20 per line), the contrast needs to be decreased. To adjust the contrast: On the NEMA 4X transmitter, press or on the keypad several times to increase or decrease the display contrast. On the explosion proof transmitter (no local keypad), the contrast adjustment is performed from the setup menus. See Contrast Adjustment for the Explosion Proof Transmitter below for a detailed description. Note: communications must be established with the gauge via the RS-232 or RS-485 serial port. If adjusting the contrast does not fix the display problem: Verify the power supply at the source. Remove power from the transmitter, then remove the cover and verify that the power cable wires are securely fastened to the correct terminals and that the connectors for RS-485 or RS-232 serial port are correctly wired. If you have display problems when using a remote terminal or the HHT, verify that the communication settings are set properly. The default gauge settings are 7 data bits, even parity, 1 stop bit, and 9600 baud. Contrast Adjustment for the Explosion Proof Transmitter It is assumed that communications have been established with the gauge via the RS-232 or RS-485 serial ports using either a Thermo Scientific HHT or a remote terminal or PC.

Failure to do so may result in damage to the VPI board. Current Board Problems Relay Problems If you suspect a problem with the current output, attach an ammeter in series with the current output load and verify the current output at various levels. Use the commands in the User service & related items submenu, located under the Security, service, and diagnostic functions top-level menu, to hold the current output at specific levels for testing (Refer to Chapter 9 of the DensityPRO+ Operation manual for details). If you suspect a problem with a relay output, you can attach a continuity tester to the suspected relay output and use the Test relays commands to test relay operation. (Refer to Chapter 9 of the DensityPRO+ Operation manual for details.) Scintillation Detector Danger: Remove all power from the unit before servicing. Electrocution can result if power is present. In hazardous locations, ensure that power is removed from the detector before removing the housing cover. Be sure that the housing cover has been replaced and that the grounds are properly connected before reapplying power. Caution: Close the shutter on the source housing before servicing the detector unit. AC Power Supply Fuse Caution: For reliable operation and to maintain safety approvals, the F1 fuse on the AC power board must be replaced with an approved fuse. See the Installation Wiring Diagram (868515) or Appendix B Parts List. Thermo Fisher Scientific 4-7

48 Chapter 4 Troubleshooting and Maintenance DensityPRO+ Factory Wiring Jumper Settings The detector board (positioned horizontally at the bottom of the electronics chassis) mounts on the photomultiplier tube. A factory-installed cable connects the detector board to the J2 connector on the CPU board. If the optional AC power board is installed, a factory-installed cable connects the J3 connector on the AC power board to the J4 connector on the scintillator adapter board. If the optional 12-to-24 Vdc converter board is installed, a factory-installed cable connects the J2 connector on the 12-to-24 Vdc converter board to the J4 connector on the scintillator adapter board. Refer to Drawing sheet 2 for details of the jumper locations and pin numbering. Scintillation Detector Troubleshooting Note: Enable the service-only items in the Special functions menu before proceeding with this section. Refer to Chapter 9 of the DensityPRO+ Operation Manual for details on the service-related menus. If you suspect a detector problem, you can quickly check the detector output using the Internal value of sensor signal item in the Snapshot menu (Direct entry code ). This value (count rate in counts per second) should be much larger with the source shutter ON than with the shutter OFF (typically more than ten times larger). As a further check, if standardization has been completed, set up your standard configuration and compare the Internal value of sensor signal to the STD value in use (standardization value) displayed in the Sensor standardization submenu of the Gauge fine tuning menu (Direct entry code ). If the gauge was working properly when it was last standardized, the two values should be similar. (The match is not exact because the STD value is filtered and corrected for background radiation and source decay.) If the displayed signal value is not behaving correctly, be sure to consider misalignment of the gauge head, buildup or wear, debris in the beam path, or faulty shutter operation before testing the detector signals. If you can eliminate these other factors, the cause is probably on the CPU board. Verify that the connectors on the cable connecting the Detector board to the CPU board are securely seated on both boards. If the problem remains, call Thermo Fisher for assistance. 4-8 Thermo Fisher Scientific

49 DensityPRO+ Chapter 4 Troubleshooting and Maintenance Ionization Detector Caution: Close the shutter on the source housing before servicing the detector unit. AC Power Supply Fuse Caution: For reliable operation and to maintain safety approvals, the F1 fuse on the Ion Chamber detector board must be replaced with an approved fuse. See Appendix B Parts List. Ion Chamber Detector Troubleshooting Note: Select Do display service-only items in the Special functions menu before proceeding with this section. If you suspect a detector problem, you can quickly check the detector output using the Internal value of sensor signal item in the Snapshot menu. The value displayed with the source shutter ON should be much larger than with the shutter OFF (typically more than ten times larger). As a further check, set up your standard configuration and compare the sensor signal to the STD value displayed in the Gauge fine tuning standardization menu. If the gauge was working properly when it was last standardized, the two values should be similar. (The match is not exact because the STD value is filtered and corrected for background radiation and source decay.) If the displayed signal value is not behaving correctly, be sure to consider misalignment of the gauge head, pipe buildup or wear, debris in the beam path, or faulty shutter operation (especially on density probes) before testing the detector signals. If you can eliminate these other factors, the cause is probably in the VPI board or in the detector. To see which is at fault, use an ammeter to measure the detector signal at the ionization detector input of the transmitter s VPI board. (The terminal positions for each connector are labeled inside the transmitter cover or refer to the appropriate wiring diagram.) The current should be between 1 and 10 ma under normal operation, and should drop (typically more than 90 percent) when the source shutter is turned from ON to OFF. If the measured current appears to behave correctly, then the VPI board is probably at fault. Otherwise, check the signal cable between the detector and transmitter for opens or shorts. If the cable is intact, the cause is probably in the detector. Contact Thermo Fisher for assistance. Thermo Fisher Scientific 4-9
