Installation Licensing

Licensing

Warning The instrument is a nuclear device regulated by federal and / or state authorities. You are responsible for knowing and following the pertinent safety and regulatory requirements. Refer to Gamma Radiation Safety (p/n 717904) for a summary of these requirements. ▲

Warning Moving or removing an installed source housing or any assembly that includes a source housing requires a person who is specifically licensed to install and commission Thermo Scientific source heads. ▲

In the United States, your general license permits you to own and install all of the instrument’s components, including the source head. However, you may not commission the instrument (remove the lock and open the source housing shutter for the first time) without a specific license authorizing radiation commissioning of the instrument. In Canada, you are only allowed to remove the instrument from the shipping container if your CNSC license has a condition authorizing mounting / dismounting of devices. For assistance obtaining a license or commissioning / decommissioning the instrument, contact Thermo Fisher.

Guidelines Warning Do not install the system in any hazardous area other than those approved. Refer to the equipment tag for the specific approvals applicable to the configuration of your instrument. ▲

Warning Do not apply power to the instrument in any hazardous area unless the safety ground is properly wired inside the instrument and the cover is properly installed. ▲

Warning Remove all power from the unit prior to opening the transmitter enclosure. Electrocution can result if power is present. ▲

The following procedure applies to all transmitter boards except for the AC power supply. Refer to “AC Power Supply” later in this chapter.

1. Verify that power has been removed from the transmitter.

2. Remove the screws on the faceplate (cover) and open it.

3. If replacing a board, remove the board that is currently installed:

a. Unplug any screw-in terminal connectors that have been wired from the board.

b. Remove the board retaining screw in the upper card guide.

c. Firmly but carefully push down on the top edge of the board to disengage the board connector from the transmitter. Pull up and out on the bottom edge of the board to remove it.

4. Align the board with the upper and lower card guide slots, and insert the board into the slots.

5. Line up the 3-pin by 16-pin male connector on the board with the corresponding connector on the back of the transmitter.

6. Firmly but carefully push on the board until the connector is fully seated.

7. Insert and tighten the board retaining screw in the upper card guide.

8. Connect the screw-terminal connector(s) to the corresponding replacement board connectors.

9. Refer to Chapter 4 for wiring procedures.

10. Close the transmitter and tighten the cover screws.



AC Power Supply C Power Supply

Warning If a power supply fails, the input capacitor might still be charged at a high voltage (up to 400 volts). ▲

Caution Do not remove the four screws that secure the power supply to the mounting bracket. The power supply and mounting bracket are placed as a single unit. ▲

Note The old power supply assembly is not field repairable. ▲

1. Follow the procedure in step 3 above to remove all other transmitter boards (CPU, PCB 1, PCB 2, PCB 3, and PCB 4).

2. Remove the two hold-down screws from the base of the power supply mounting bracket. These screws secure the power supply mounting bracket to the main board.

3. Disconnect cables from the power supply (AC, DC, and Protective Safety Ground). Cut the tie wrap that secures the toroid to the power supply.

4. If replacing the power supply, remove the existing power supply and mounting bracket assembly. Replace it with the new supply.

5. Connect the cables to the replacement power supply (see “Power to the Transmitter” in Chapter 4 for wiring instructions).

6. Tighten the two hold-down screws to secure the power supply to the main board. (A screw-holding screwdriver facilitates installation.)

7. Reinstall the transmitter boards.


Installation The Gauge Head

The Gauge Head Warning Installation must be in accordance with local and national electric codes for the area classifications. ▲

Warning The source housing handle must be in the OFF position during installation. ▲

Warning Do not reach inside the source housing at any time during installation. ▲


Mounting Configurations

unting 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:

● Dual chain

● Pipe saddle (cradle) mount

● Pipe spool with gauge head pre-installed

The chain mount is the most frequently used mounting configuration, as it 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. Contact Thermo Fisher for assistance. ▲

In addition to the guidelines listed earlier in this chapter, note the following when planning gauge head installation.

● 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. The gauge measures only the material that passes through the beam. Prevent suspended solids from settling out of the measured area by mounting the gauge head on a vertical section of pipe.

● For mounting 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.

Figure 3–1. Gauge installation examples



Mounting Instructions

The following sections provide installation details for the various mounting configurations. Refer to the following drawings for detector dimensions.

● 867468: 9719B scintillation detector, NEMA 4 housing

● 867469: 9720B scintillation detector, explosion proof housing

● 866778: 9701 ion chamber detector, NEMA 4 housing

● 866777: 9702 ion chamber detector, explosion proof housing


Caution Do not over tighten the bolts. ▲

For 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.

Dual Chain Mount ual Chain Mount

Details of the chain mount depend on the detector type, but the installation is similar for both types. Refer to the following drawings for mounting details.

● 867466: 9719B scintillation detector

2. For 9701/9702 ion chamber detectors, partially assemble the two tensioning bolts (hardware kit 885825) in the following order:

a. 1 tensioning bolt (large)

b. 1 flat washer: Place onto bolt next to bolt head.

c. 1 spacer ring

d. 2 Belleville washers with concave sides together

e. 1 special nut: Thread nut securely onto the bolt end.

3. For 9719B/9720B scintillation detectors, partially assemble the two tensioning bolts (hardware kit 885826) in the following order:

a. 1 tensioning bolt (large)

b. 1 chain: Place center ring of chain over the bolt head.

c. 1 bar nut: Position the guard tube towards the bolt head.

d. 1 special nut: Thread the 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.

Note 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. ▲



Note You may need to adjust chain links (thread more or fewer links through each slot) to allow for pipe size tolerance, insulation, etc. Start with approximately 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:

a. Position the upper chain, including the tensioning bolt assembled earlier, over the detector’s top mounting arm.

b. Place a spacer ring and two Belleville washers with concave sides together onto the pilot end of the special nut.

c. 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.

d. 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 will not 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.

Pipe Saddle (Cradle) Mount

A pipe saddle, or cradle, mount consists of two identical mounting plates that are bolted together on opposite sides of the process pipe.

Refer to drawing 85726N and follow the steps below to install a gauge head with a pipe saddle mount.



Figure 3–3. Pipe saddle mount

1. Assemble the two halves of the saddle mount onto the process pipe using the supplied nuts, bolts, and washers. Thread the nuts and bolts together, but do not tighten them.

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 Mount ipe Spool Mount A pipe spool is normally a 30-inch section of pipe with either mounting plates or a complete gauge head already installed. Often, a length of the required pipe is sent to Thermo Fisher to be converted into a pipe spool mount.

Caution Use correct pipe fitting techniques suitable for the pipe being used and the process material that the pipe will handle. ▲

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.

c. Insert the wires and make connections as shown in the installation wiring drawing.

d. Tighten the screws in the connector to secure the wires and plug the screw-terminal connector back into the corresponding onboard connector.

e. The optional temperature compensation board uses a spring terminal block connector. For each wire to be connected, use a flat screwdriver to push and hold the appropriate tab down. Insert the wire, and then release the tab to secure the wire.

7. When the detector wiring is complete, replace and secure the detector housing cover.



For Ion Chamber Detectors

Use the following procedure when wiring 9701 and 9702 ion chamber detectors. You will need a 1/8-inch bladed screwdriver.

Note While wiring the ion chamber detector, locate the Hi-Meg label on the detector circuit board. A large resistance value will be written on this label (for example, 4.7 x 1011). Write down this value along with the detector’s serial number. The Hi-Meg value will be needed during the gauge setup to fine tune the gauge. ▲

1. Make sure all source shutters are in the “OFF” position.

2. Make sure all power to the gauge is turned off.

3. Remove the housing access cover:

For the 9701 detector, remove the bolts that secure the cover to the housing.

For the 9702 detector, loosen the screw on the cover retaining bracket and slide the bracket off of the housing cover. Unscrew the housing access cover (two lugs are provided on the top of the cover to aid in the removal of the cover).

4. Remove the foam insulator and the two brass-colored centering plates.

5. As shown in the installation layout drawing 868695, the AC power and signal wiring should not be run in the same conduit for more than three meters (ten feet). If required, use a conduit splitter and lay one conduit for the signal cables and a second conduit for the AC power wiring.

6. Pull each cable through the conduit and into the enclosure. Leave approximately 150 mm (six inches) for strain relief. Secure the conduit, making sure it is completely sealed.

7. Connect the input power, the ion chamber signal wires, and the temperature compensation board wires, if applicable, as shown in the installation wiring diagram 868697.



Note Connect the AC wiring Earth ground to the internal safety ground terminal (on the inside of the detector housing) as shown in the wiring diagram. Do not connect the shield from the signal cable at the detector end. ▲

8. Position the two brass-colored centering plates over the circuit board with the smaller plate on top of the larger plate. Be careful to not pinch any wiring. Thread in and finger-tighten the four screws that secure the centering plates.

9. Insert a medium-sized flat blade screwdriver into the stepped (jagged) opening in the larger centering plate. Twist the screwdriver to push the two plates apart until the detector is locked in position. Tighten the four screws to secure the centering plates and the detector.

10. When the wiring is complete, replace and secure the detector housing cover.

For the Transmitter EMC Requirement for

ATEX Version of 1400S Transmitters

In order for the 1400S transmitter to meet electromagnetic emission requirements for CE-EMC approvals, ferrite clamps must be installed within the transmitter enclosure on all power and signal wiring going into and out of the transmitter housing.

One ferrite clamp is installed on the wires of the AC power supply input. Five additional ferrite clamps are provided with the EMC ferrite clamps kit (p/n 868773). The installation procedure accompanies the kit. It is also provided in Appendix D.

Note The ferrite clamps are only used in the ATEX version of the 1400S transmitter. They are not required for the CSA version or the plastic 1400A transmitter. ▲



Procedure The transmitter has slots for the following boards:

● Optional AC power supply

● CPU board

● PCB 1: Standard current I/O / DC power board

● PCB 2: Optional current I/O board with two contact inputs and two optional relays

● PCB 3: Optional current I/O board with two contact inputs and two optional relays

● PCB 4: Voltage/current pulse interface (VPI) board (p/n 868712), used to interface with the detector

Follow this general procedure for wiring boards installed in the transmitter, RS232 or RS485 serial ports, relay contacts, contact closure inputs, 4–20 mA current output(s), and detector signal cables to the transmitter. You will need a 1/8-inch bladed screwdriver.

Note CSA certified fittings must be used to maintain CSA rating for the enclosure. ▲

1. Ensure power is removed, and open the enclosure cover.

2. Remove the plugs only from the cable conduit holes you will use. The holes are labeled on the transmitter enclosure.

3. Pull the cable through the fitting on the end of the enclosure. Leave approximately 6 inches (150 mm) of stress relief. Secure the conduit, ensuring it is completely sealed.

4. For ATEX versions of the 1400S: Install a ferrite clamp on all wiring. You will need kit 868773. Refer to Appendix D.

5. Connect a cable to a PCB as follows:

a. Remove the plug-in screw terminal connector from the board connector. If the connector is tight, brace the board with your hand to remove the screw terminal connector, but be careful to not touch any circuit components.

b. Loosen the terminal screws on the connector. Insert the wires into the connector and make connections as shown in the appropriate installation wiring drawing.


Wiring Power Supply Wiring

c. Tighten the terminal screws to secure the wires.

d. Plug the screw-terminal connector back into the corresponding on-board connector.

6. When all connections are complete, close and secure the transmitter cover.

Detector Type Selection Three, two-pin headers (JP1, JP2, and JP3) are located along the edge of the VPI board near the top of the board. A jumper should be installed on one (and only one) of these headers to indicate the detector type as follows:

● JP1: Ion chamber detector

● JP2: Scintillation detector – SGD mode

● JP3: Scintillation detector – PRO mode

Caution Remove power from the transmitter before changing jumper settings. Failure to do so may result in damage to the VPI board. ▲

Optional Wiring For optional wiring, refer to installation wiring drawing 868680-2.

Relays I/O boards installed in transmitter slots PCB 1 through PCB 3 can have two relays each, allowing for a maximum of six relays. Connector J1 is for relays and is only installed on the PCB if relays were specified in the order.

Relay contacts are Form C SPDT, isolated 8 A, 22 Vac. You can assign process alarms to control the relays. Refer to the DensityPRO+ user guide for details.

Current Output One current output (I/O) board is supplied as standard and installed in the PCB 1 slot. Two additional I/O boards are optionally available are installed the transmitter’s PCB 2 and PCB 3 slots.

The current output is normally shipped from the factory configured as an isolated self-powered output. You can reconfigure the current output as isolated loop-powered by removing the jumper from pins 3 and 4 of the J5 connector. In the loop-powered configuration, the user must supply +24 Vdc loop power to pin 3 of J5. Pin 2 of J5 is Iout+.

The current output is programmable between 3.8 and 20.5 mA. Refer to the DensityPRO+ user guide for details. The minimum output in the self-powered configurations is approximately 0.4 mA. The minimum output current in the loop-powered configuration is approximately 3 mA. Maximum load is 800 ohms.


Wiring Serial Communications

Contact Closure (Switch) Inputs

Two contact closure inputs are included on each I/O board. They are dry contact inputs between ground and switch 1 and ground and switch 2. The gauge can be configured to execute a command or other function upon a user-provided contact opening or closing. Refer to the DensityPRO+ user guide for details on assigning commands to the contact closure inputs.

Temperature Compensation

Temperature compensation circuitry with 2-wire or 3-wire 100 ohm platinum RTD is optionally available. For 9701/9702 scintillation detectors, connections are made at J19. For 9719B/9720B ion chamber detectors, connections are made from the temperature compensation board. For the 1400A/1400S transmitter, connections are made at J1A of the VPI board installed in the PCB 4 slot. Reference the appropriate installation wiring diagrams for specific wiring information.

Flow Input There is a provision on the VPI board for a user-provided 4–20 mA flow input (pins 6 and 7 of connector J1A). Refer to the DensityPRO+ user guide for details on how to configure the gauge to use the flow input signal.

Serial Communications

The transmitter provides one RS232 single-drop serial interface. One RS485 multi-drop serial interface is optionally available. Screw-terminal connectors for both ports are located on the CPU board.

The optional RS485 connector (J6) 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 RS485 port. The HHT can be connected directly to the RJ-11 connector.

Both the RS232 and optional RS485 ports are always active and provide independent access to the measurement readings and software functions. The setup menus, however, can only be accessed by one port at a time. For information on configuring communications, refer to the DensityPRO+ user guide.


Wiring Serial Communications

Optional RS485 Wiring

Connecting a PC serial port (COM) to the optional RS485 port on the gauge requires an RS485/RS232 converter (p/n 670045). The J6 connector on the transmitter CPU is for the RS485 connections. Refer to installation wiring drawing 868680-2 and make the RS485 connections as follows.

1. Connect +DATA and –DATA on the RS485 connector (J6) to the corresponding connections on the RS485/RS232 converter.

2. Connect the RS485/RS232 converter to the PC using a standard DB9 serial cable.

RS485 Termination If you are having trouble using another device on the RS485 chain, verify that it is properly terminated for its position on the chain. To terminate a device, connect a 120 resistor between its RS485 +/– data terminals. Never terminate more than the first and last device in the chain.

The transmitter includes a three-pin header (W4), located near the bottom-front edge of the CPU board next to the RS485 connector (J6), to terminate the RS485 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 RS485 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 RS485 line is not terminated at the transmitter.

RS232 Wiring COM1 or COM2 on a PC can be connected directly to the transmitter RS232 port. This connection requires five wires: ground, TX, RX, RTS, and CTS. The RS232 port connector (J8) is located on the transmitter CPU board. Connections for standard DB9 and DB25 PC serial port connectors are listed in the table below.

Appendix D

Adding Ferrite Clamps to 1400S Transmitter

Note The ferrite clamps are only used in the ATEX version of the 1400S transmitter. They are not required for the CSA version or the plastic 1400A transmitter. If needed, the ferrite clamps kit may be ordered separately. ▲

In order for the 1400S transmitter to meet electromagnetic emission requirements for CE-EMC approvals, ferrite clamps must be installed within the transmitter enclosure on all power and signal wiring going into and out of the transmitter housing.

Procedure The ferrite clamp is part of the EMC ferrite clamps kit (p/n 868773). The kit consists of the following:

● Five ferrite clamps (p/n 5-2720-007)

● At least one clamp “key”

● The procedure

The clamp key is used to remove the ferrite clamp from the wire during wiring changes.

Figure D–1. Ferrite clamps

A ferrite clamp will need to be installed on all wiring that enters or exits the transmitter enclosure. This may be a shielded twisted pair or a bundle of individual wires. The limitation is that the wires through one clamp cannot exceed 5 mm in diameter. Also, all of the clamps MUST be installed within the enclosure.

Thermo Fisher Scientific DensityPRO+ Installation Guide D-1

Adding Ferrite Clamps to 1400S Transmitter Procedure

D-2 DensityPRO+ Installation Guide Thermo Fisher Scientific

Figure D–2. Ferrite clamps installed within enclosure

As shown in Figure D–2 the ferrite clamp can be placed around a shielded twisted pair cable or a bundle of individual cables, as long as the diameter of the bundle does not exceed 5 mm (a little over 3/16”).

The ferrite clamp kit (p/n 868773) contains five clamps. Depending on your wiring scheme, you may need additional clamps. They can be ordered using part number 5-2720-007.

For example, in a Thermo Scientific DensityPRO+ system with a scintillation detector, flow input, and three outputs, there will be eight shielded twisted pair cables and one power cable. This system would require a total of nine ferrite clamps. So you would need either two kits or one kit and four additional clamps to be EMC compliant.

Note All ATEX version 1400S transmitters shipped after August 2009 will contain one ferrite clamp kit and will have one ferrite clamp installed on the AC voltage input wiring. ▲

Note If the locking mechanism of the clamp should fail, a plastic wire tie can be used to secure the clamp around the wire. ▲
