Mount the transmitter in one of the following two ways:
● With four screws: Place one screw through each of the four holes in
the transmitter enclosure’s flange and tighten.
● With four nuts, four bolts, and eight washers: 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.
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

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.)
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. ▲
Warning Use proper lifting procedures during installation to avoid
injury. ▲
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.
● 866778: 9701 ion chamber detector, NEMA 4 housing
● 866777: 9702 ion chamber detector, explosion proof housing
Warning Use proper lifting procedures during installation to avoid
injury. ▲
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.
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.
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.
Pipe Saddle (Cradle)
Mount
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.
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.
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.
Wiring should be performed in the following order:
1. Power to the transmitter and detector
2. The detector to the transmitter
3. Optional wiring:
a. Relay contacts
Preparation reparation
b. 4–20 mA current output(s)
c. Contact closure inputs
d. Optional temperature compensation board to the transmitter
e. Serial communications
Review the following carefully prior to connecting any wiring.
Warning Remove all power from the unit before making any connections.
Electrocution can result if power is present. ▲
Warning All wiring must be done by qualified individuals in accordance
with applicable codes such as the NEC (National Electric Code)
ANSI/NFPA 70 specifications or the Canadian Electrical Code Part 1.
Only approved conduit, boxes, and fittings may be used.
Warning Do not apply power to the unit in any hazardous area unless the
safety ground is properly wired inside the unit and the cover is properly
installed. ▲
Warning For hazardous location installations, the cable entries must be
sealed per the installation layout drawing 868695. For non-hazardous
location installations, the cable entries into the enclosures must be sealed to
prevent passage of gas or vapors. The surrounding atmosphere or liquids
should not affect the sealing compound. The minimum thickness of the
sealing compound should be 16 mm (5/8”). ▲
Warning If metal conduit is used, the conduit must be grounded. ▲
Warning Before wiring, verify that the source shutter is in the closed
(OFF) position. ▲
The installation layout drawing 868695 provides general guidance for
routing the cables between the detector and the transmitter. The drawings
below provide instructions on wiring the detector and transmitter.
● 868697: Installation wiring, 9701/9702 ion chamber detector

Note To meet the requirements of CSA 1010.1, the input DC terminals
must be supplied from an SELV (Safety Extra Low Voltage) source. ▲
With 24 Vdc power, the 1400A and 1400S transmitters are designed to
operate on 20–28 Vdc. The maximum input power requirement is 12 VA
when all options are present.
Connections are shown in the table below.
Table 4–4. 24 Vdc power wiring for 1400A/1400S transmitters
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.
Note 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 and 2 on the scintillation adapter board and shorting JP3
on the VPI board. ▲
Note Install two jumpers on P2. Jumper pin 1 to pin 3 and pin 2 to pin
4. ▲

Optional Wiring
Relays
Current Output
For optional wiring, refer to installation wiring drawing 868680-2.
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.
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 selfpowered configurations is approximately 0.4 mA. The minimum output
current in the loop-powered configuration is approximately 3 mA.
Maximum load is 800 ohms.
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 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.
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.
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.
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 bottomfront edge of the CPU board next to the RS485 connector (J6), to
terminate the RS485 connection.
RS232 Wiring
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.
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.
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 275 or 375 Field Communicator. Refer to the
DensityPRO+ HART operation manual (p/n 717816).
