Source-Detector Configurations
Source-Detector
Configurations
The gauge is comprised of a source housing that contains the radioisotope
source and the detector-transmitter that contains the scintillation detector
and electronics. Sources are available in a fan beam or strip source
configuration. For most fan beams, the beam angle spreads at a 45° angle in
the vertical dimensions. A 30° beam angle spread is available with model
5210, and 60° beam angle spreads are available with models 5205B,
5206B, 5207B, and 5208B.
Strips sources emit radiation evenly along the length of the vessel from the
source and measure the radiation level reaching the detector after passing
through the vessel walls and the process material.
The scintillation detector is available in lengths ranging from 1 to 12 feet,
in 2-foot increments. For a tall or narrow tank, multiple sources and / or
detectors might be required. Contact Thermo Fisher. The specific source detector configuration depends on the application. Three possible
configurations are illustrated below.
Figure 3–1.
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. 
Instrument approvals are listed in Appendix B.
3-2 LevelPRO Installation Guide
Thermo Fisher Scientific
Hardware Installation
Guidelines
General
Review the following guidelines when planning gauge installation:
1. Correct power source is available. See “Power Requirements” later in
this chapter.
2. You will need to supply the necessary brackets and hardware required
for mounting the gauge to the vessel.
3. Operating temperature range: -40°C to +60°C (-40°F to +140°F).
4. There should be enough clearance to install and service the source
housing and the detector. Refer to the appropriate dimensional
drawings in the drawing appendix.
5. Position the source housing so the radioactive source identification tag
is visible. Mount it so the tag is upright.
6. The gauge should not be mounted where process overflow or other
material can collect in the beam path. The source housing shutter
mechanism must be kept free of debris.
7. If the handheld terminal will be used for configuration, the connection
must be located in a safe area.
System Power
Requirements
Protective Earth
Grounding
Thermo Fisher Scientific
Ensure the correct power source is available. One of the following input
power sources is required: 24 Vdc ± 20% or 115/230 Vac ± 15%, 50/60
Hz (requires optional AC power board). The maximum power requirement
is 12 VA. Both DC and AC power may be supplied to the gauge at the
same time. The gauge will draw power from whichever input source
provides the higher DC source voltage.
The LevelPRO enclosure provides internal safety ground and external
safety ground lugs (reference drawing 868503) for Safety Protective Earth
Grounding. The external safety ground lug is used to connect the unit to
Earth Ground. The internal safety ground lug is used to connect the AC
power input ground line.

Safety
Disconnecting
Means
Requirements
As a permanently connected equipment, the LevelPRO gauge requires a
switch or circuit breaker as the means for disconnection. The customer
needs to prepare the switch or circuit breaker according to the following
requirements:
1. A switch or circuit breaker must be included in the building
installation.
2. It must be in close proximity to the equipment (LevelPRO) and within
easy reach of the operator.
3. It must be marked as the disconnecting device for this equipment
(LevelPRO).
Detector-Transmitter
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 For hazardous location installations, the cable entries must be
sealed per the installation layout drawing (868502). 
Warning For non-hazardous location installations, the enclosure cable
entries must be sealed with a compound to protect against the passage of
gas or vapors. The sealing compound should not be affected by the
surrounding atmosphere or liquids. The sealing compound must have a
thickness of at least 5/8 inch (16 mm). 
Warning Use proper lifting procedures during installation to avoid injury.
Refer to drawings 868672 or 868674 (water-cooled units) for weights and
dimensions of the detector housing. 
3-4 LevelPRO Installation Guide
Thermo Fisher Scientific
Hardware Installation
Detector-Transmitter
Alignment
Refer to drawings 868502 and 868672 (868674 for water-cooled units) for
mounting dimensions of the detector-transmitter.
The source housing and detector are normally installed across the diameter
of the vessel. If mechanisms internal to the process vessel would interrupt
the radiation beam, you can move the installation slightly off center.
Contact Thermo Fisher if the angle between the source and detector will be
less than 130°, as illustrated below.
Figure 3–2.
It is important to mount the source housing securely, since any movement
or change in alignment can affect the gauge’s calibration. When mounting
the source housing, be sure to include a means of aiming the beam several
degrees left or right so the source beam can be aligned with the detector.
The exact mounting method will vary depending on the application.
Align the center of the source beam path as closely as possible with the
centerline of the detector housing. The source beam is narrow horizontally,
and the radiation is uniform only in the primary (center) part of the beam.
The shielding in the source housing attenuates the radiation in the
secondary part of the beam. The sensitive area of the detector is the center
2-7/8 inches (73 mm) across the width of the detector’s housing. This area
should lie entirely within the primary beam.
Figure 3–3.
To determine the primary beam width, you will need the included angle of
the beam. For example, the included angle is typically 12°. In this case, the
primary beam width will be 1 foot wide 5 feet away from the source. At 10
feet away from the source, the beam width will be 2 feet wide, and so on.
This is illustrated in the figure below.
Thermo Fisher Scientific
LevelPRO Installation Guide
3-5
Hardware Installation
Detector-Transmitter
Figure 3–4. Determining primary beam width
Measurable Range
Before beginning the installation, verify that the measurable range (the
range over which the process level can be measured) of the proposed
installation meets the requirements of your application. The top and
bottom of the measurement range depend on the source type (fan or strip),
the detector length, and the position of the source relative to the detector’s
sensitive length. Sensitive length refers to the part of the detector that
senses radiation.
Note The sensitive length of the detector is approximately the length from
the upper mounting bolt to the lower mounting bolt. 
Top of Range
For a source with a fan beam, the top of the range is at the top of the
sensitive length of the detector or at the center of the source housing,
whichever is lower.
For a strip source, the top of the range is at the top of the sensitive length
of the detector or at the top of the active length of the source, whichever is
lower.
Bottom of Range
For a source with a fan beam, the bottom of range is the point where a line
drawn from the source to the detector centerline at the bottom end of the
detector’s sensitive length intersects the inner vessel wall nearest the
detector. This is illustrated in Figure 3–5.
Note If the vertical beam width of the source does not fully illuminate the
sensitive length of the detector, the bottom of the range is the point at
which the lower limit of the source beam intersects the inner vessel wall. 
3-6 LevelPRO Installation Guide
Thermo Fisher Scientific
Hardware Installation
Detector-Transmitter
For a strip source, the bottom of the range is at the bottom of the detector’s
sensitive length or at the bottom of the active length of the source,
whichever is higher.
In Figure 3–5, the top of the source beam (center of the source housing) is
aligned with the top of the sensitive length of the detector. Thus, the top of
the measurable range is defined by the horizontal line drawn from the top
of the sensitive length of the detector to the center of the source housing.
The bottom of the range (BR), measured from the top of the measurable
range, is provided by the formula:
BR = BD – [PD X BD / SD]
or, equivalently,
BR = BD X [1 – (PD / SD)]
where
BD = distance from top of range to the bottom of the sensitive length
of the detector (in Figure 3–5, BD = sensitive length of detector).
PD = distance from the center of the detector to the inner vessel wall.
SD = distance from the center of the detector to the center of the
source.

The Source Housing
The Source
Housing
Warning In the United States, you may uncrate and mount the source
housing, but you may not remove the shipping bolt unless you are licensed
to commission the gauge. In Canada, you must have a license condition
permitting mounting / dismounting, and without this condition, users may
not remove the source from the shipping crate. 
Warning Use proper lifting procedures to avoid injury. 
The scintillation detector can be used with either a fan beam source or a
strip source. Normally the scintillation detector is mounted so that the top
of the detector’s sensitive length is even with the top of the fan beam or
even with the top of the active length of the strip source.
Fan Beam Source
Guidelines
Note the following if using a source with a fan beam.
1. The vertical angle of the fan beam is typically 45°. This means that the
beam’s vertical range is equal to the horizontal distance between the
detector and the source. (In special cases, the angle may be 30° or 60°.
Contact Thermo Fisher for guidance.)
2. Mount the source housing so that the top of the fan beam is aligned
with the top of the sensitive length of the detector.
3. Install the source housing with its mounting face as close to the process
vessel as practical, with no structural material (mounting tabs, brackets,
etc.) between the beam area and the vessel.
4. The mounting should ensure accurate beam alignment with the
detector and provide for easy left-right angular adjustment. The top of
the beam should be even with the top of the measurable range.
Thermo Fisher Scientific
LevelPRO Installation Guide
3-9
Hardware Installation
The Source Housing
Strip Source
Guidelines
Note the following if using a strip source.
1. Refer to the source housing drawings to determine the position of the
active length of the strip source and other mounting dimensions.
2. Secure the housing with the 1/2-inch (12 mm) bolts and lock washers
(six places). The housing mounting face allows clearance for bolts or
studs extending up to 2-1/4 inches (57 mm) from the mounting
surface.
3. For best results, the measurable range should be less than the active
length of the strip source(s). Position the strip source so that the
bottom of the active length of the source is even with the minimum
level to be measured. If the measurable range must be greater than the
active length of the strip source, position the top of the active length of
the source so that it is even with the maximum level to be measured.
4. The mounting surface should be vertical. The mounting should ensure
accurate beam alignment with the detector and provide for easy leftright angular adjustment.
5. Install the source housing with its mounting face as close to the vessel
as practical, with no structural material (mounting tabs, brackets, etc.)
between the beam area and the vessel.
Shutter Actuator
3-10 LevelPRO Installation Guide
If your source housing includes a pneumatic shutter actuator, refer to
drawing 866664 for installation details.
Thermo Fisher Scientific
Hardware Installation
Multiple Detectors / Source Housings
Multiple
Detectors /
Source Housings
Certain applications may require the use of multiple detectors and / or
multiple source housings to span the desired measurable range.
If multiple detectors are used, the uppermost unit should be mounted so
that the top of its sensitive length is even with the top of the measurable
range. The remaining units should be mounted so that the top of each
detector’s sensitive length is aligned with or slightly overlaps the bottom of
the sensitive length of the detector mounted just above it.
If more than one source housing is required, the top source housing should
be installed with the top of its beam even with the top of the desired
measurable range. The other source housings should be spaced evenly along
the vertical dimension of the vessel. For example, if the range of interest is
12 feet and three fan beam sources are used, the source housings should be
spaced four feet apart.
The installation / arrangement drawings provide mounting dimensions for
several configurations (refer to drawings 868566 through 868571).
When mounting two or more pairs of strip sources and detectors on a small
diameter tank, adjacent pairs of source housings and detectors may be
rotated by 90° if necessary. The source housing and detector for each
source-detector pair at the same height must still be mounted on opposite
sides of the tank (180°). After mounting the uppermost source-detector
pair, the position of the source housing and detector in the next lower pair
may be rotated by 90° and so on.

configuration. Should you need to replace the CPU board, note the jumper
settings for connectors J7 (current output configuration) and J11 (system
configuration) before replacing the board. After installing the new board,
verify that the jumpers are set properly for your system configuration.
Figure 4–1 shows the location of connectors and jumpers.

The CPU Board
System
Configuration
J11 on the CPU board is the connector for system configuration jumpers.
Move the jumper at pins 5 and 6 to pins 4 and 5 to enable the CPU to
recognize optional relays mounted on the power supply board. Later units
will be shipped with the jumper already at pins 4 and 5, even if the relay
option is not purchased.
Move the jumper to pins 1 and 8 of the J11 connector to erase system
memory.
Caution Placing a jumper across pins 1 and 8 on the J11 connector erases
system memory. All user-entered parameters are erased and reset to factory
defaults. 
If you are going to erase memory by placing a jumper across pins 1 and 8,
first remove power from the detector-transmitter. Note the location of the
jumpers on the J11 connector. Place a jumper across pins 1 and 8, apply
power, and leave power on for approximately 30 seconds to erase memory.
Remove power and restore the configuration jumpers to their original
settings.

Power Supply
Power Supply
The system is designed to operate on 24 Vdc. If the optional AC power
board is installed, the system can also operate on 115 or 230 Vac (± 15%),
50/60 Hz. The maximum input power requirement is 12 VA. If both AC
and DC power are supplied to the detector, the detector will draw power
from whichever source provides the higher DC voltage.
The maximum length of the cable that can be used to supply power varies
depending on the wire gauge. Refer to the wiring drawing (868503) for
cable information and other wiring details.
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. For
intrinsically safe systems, refer to ANSI / ISA RP 12.6. 
Note To meet the requirements of CSA 1010.1, an external switch or
circuit breaker must be installed to allow the power source to be
disconnected from the gauge. In addition, protective bonding (grounding)
must always be provided, even if DC power is used. 
DC Power
J12 on the CPU board is the connector for the DC source voltage wiring.
Refer to the wiring drawing (868503) and to the table below for
connections.

Serial Communications
Serial
Communications
The gauge provides one RS232 single drop and one RS485 multi-drop
serial interface. Screw terminal connectors for both ports are located at J3
on the CPU board.
The RS485 connector includes the +8 Vdc required to power the Thermo
Scientific 9734 handheld terminal (HHT) as well as the +DATA and
–DATA connections. An RJ11 (phone jack) connector is also provided for
the RS485 port at J4 on the CPU board. The HHT can be connected
directly to the RJ11 connector in safe areas.
Both ports provide independent access to the measurement readings and
software functions. They are always active and can be used to display
measurements. The setup menus, however, may only be accessed by one
port at a time.
RS485 Wiring
Connecting the serial (COM) port on a PC to the RS485 port on the
gauge requires the RS485 / RS232 converter (p/n OTO515D).
1. Connect J3-12 (+DATA) and J3-11 (–DATA) to the corresponding
connections on the RS485 / RS232 converter.
2. Connect the converter to the PC using the supplied DB9 serial cable.
3. Refer to drawings 868519 and 868503 for additional details.
Initial Setup for PartyLine Communications
To communicate with multiple gauges via a RS485 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 be able to
communicate with each one individually. Disconnect each gauge from the
party-line in turn and communicate with the disconnected gauge directly.
Alternately, you can remove power from all gauges except one and assign a
unit number to the powered gauge.
If you have 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-ohm resistor between its RS485 + / - data terminals. Never
terminate more than the first and last device in the chain.

HART Communications
RS232 Wiring
The serial port on a PC (COM1 or COM2) can be connected directly to
the RS232 port on the gauge. This requires five wires: ground, transmit
(TX), receive (RX), request-to-send (RTS), and clear-to-send (CTS). The
connections between the RS232 port (J3 on the CPU board) and the PC
serial port are summarized in the table below for standard DB9 and DB25
PC serial port connectors.

To communicate with the gauge from a PC requires that the PC be
running a terminal emulation software. The default communication
settings for the gauge’s RS485 and RS232 ports and for the HHT are: 7
data bits, Even parity, 1 stop bit, 9600 baud.
Refer to the LevelPRO user guide for additional details about setting up
and using serial communications.
HART
Communications
The HART communication protocol is supported over the 4–20 mA
current output with the HART interface board. The HART interface
board is an optional daughter board that is wired via a cable to J6 on the
CPU board. Communication with the gauge is via the 275 or 375 Field
Communicator from Emerson Electric Co. Refer to the LevelPRO HART
operation manual (p/n 717817) for detailed instructions.
Note HART communication protocol allows you to configure and
calibrate the gauge in most applications; however, due to limitations of the
protocol, the complete range of functions is only available when using the
Thermo Scientific Model 9734 handheld terminal and the RS485 port. 

Contact Closure
Inputs
With FOUNDATION fieldbus, the gauge provides users with access to
control or program parameters via a host system. The fieldbus connector is
accessible from the faceplate of the LevelPRO, and the only connections
required for operation are to the H1 bus.
Refer to the LevelPRO with FOUNDATION fieldbus application guide for
specific wiring instructions.
The contact closure inputs are dry contact inputs between ground and
Switch 1 and ground and Switch 2 at J13 on the CPU board. 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
LevelPRO user manual for instructions on assigning commands to the
contact closure inputs.
When operating in “cascade” mode, where multiple units are wired
together to act as a single detector, contact closure Switch 2 is dedicated to
performing the cascading function. Refer to drawings 868503 and 868529.
Current Output
Following are the configurations available for the 4–20 mA current output:

Isolated, loop-powered (default)

Non-isolated, self-powered

Isolated, self-powered output (requires optional piggyback board p/n
886595)
The isolated, loop-powered or non-isolated, self-powered configurations
can drive an 800 ohm maximum load over the full current output range.
The isolated, self-powered current output can drive a maximum load of
1000 ohms. The current output is programmable between 3.8 and 20.5
mA. The fault low condition for the current output is 3.6 mA or less, and
the fault high condition is 20.8 mA or greater.

Current Output
Isolated, Loop
Powered
Configuration
The default current output configuration is isolated, loop-powered. With
this configuration, the 4–20 mA loop is supplied by the customer’s PLC or
DCS. A jumper is placed across pins 4 and 5 of the J7 connector on the
CPU board. J10-6 and J10-7 are for the 4–20 mA output connections.
Figure 4–3. 4–20 mA loop powered configuration
Non-Isolated, SelfPowered
Configuration
With the non-isolated, self-powered configuration, power for the 4–20 mA
loop is supplied by the gauge, but it is not isolated from the gauge circuitry.
A jumper is placed across pins 3 and 4 of the J7 connector on the CPU
board. J10-6 and J10-9 are for the 4–20 mA output connections.
Figure 4–4. 4–20 mA non-isolated, self-powered configuration
Isolated, SelfPowered
Configuration
With the isolated, self-powered configuration, power for the 4–20 mA loop
is supplied by the gauge, and the output is isolated from the gauge
circuitry. The isolated piggyback board (p/n 886595-1) must be installed
on the CPU (see Figure 4–5). This puts the 4–20 mA output on
connections J10-6 and J10-8. No jumpers are used for this configuration.

Wiring
Cascade Mode Wiring
Cascade Mode
Wiring
For applications requiring a detector length greater than twelve feet,
multiple units can be wired together to act as one continuous detector. In
this situation, the highest or top gauge in the line, or cascade, is the master.
All wiring for the serial ports, relays, etc. is done in the master unit.
Remaining units are slave units. All slaves must be powered in the same
manner as the master (either AC or DC).
The lowest gauge in the line must be wired with its CASCADE OUT to
the CASCADE IN of the gauge directly above it. Each gauge in the cascade
is wired in this manner (CASCADE OUT to the CASCADE IN of the
next unit), up to the master gauge. The master has only a CASCADE IN.
Each gauge takes the count rate coming into it on the CASCADE IN line
from the detector immediately below it, adds the value to its own internal
count rate, and then outputs the total on the CASCADE OUT line to the
detector immediately above in the cascade.
Refer to drawings 868503 and 868529 in the drawing appendix for the
wiring requirements. Additional information on cascade mode wiring can
be found in Technical Bulletin TB-0416-019.
Auxiliary Input
Wiring
Thermo Fisher Scientific
There is an auxiliary connection on connector J10 for applications
requiring an outside 4–20 mA signal be input into the LevelPRO and used
as a form of compensation adjustment (vapor density, pressure, etc.). The
outside 4–20 mA signal should be wired so that the positive connection of
the loop is connected at J10 pin 1 and the negative side connected to J10
pin 2. The special equation is then utilized to incorporate this input into
the LevelPRO program. Refer to the LevelPRO user guide for information
on special equations.

Appendix D
Replacing the CPU PROM & HART
PROM
Note This appendix applies only to gauges that have the HART
communication option installed and have CPU software prior to version
5.15 or HART board software prior to 1.17. 
Purpose
Software has been released for LevelPRO detectors that have the HART
communication option installed. This software makes the HART
communication and the Thermo Scientific 9734 handheld terminal
(HHT) communication more reliable. This software upgrade requires that
both the LevelPRO CPU PROM and the HART board PROM be
replaced. This appendix provides the instructions for doing so.
Procedure
Due to the difficulty in reaching the HART board, it is recommended that
the detector be removed from the housing and taken to a clean, dry area to
perform this procedure.
Caution If performed in place, care needs to be taken to not drop the
PROMs or the LevelPRO. 
Once the detector is out of the housing, you will see that the CPU board is
readily accessible; however, the HART board is mounted between the
chassis plates and is difficult to access.

Replacing the CPU PROM & HART PROM
Procedure
Figure D–1. Location of CPU PROM
Caution It is strongly recommended that you use a PROM extraction tool
to remove the PROM from its socket. These can usually be purchased from
the local electronics supply store. Failure to use the proper tool can result in
damage to the PROM socket, necessitating replacement of the board. 
Figure D–2. Prom extraction tool
D-2 LevelPRO Installation Guide
Thermo Fisher Scientific
Replacing the CPU PROM & HART PROM
Procedure
If you do not have an extraction tool, a small bladed screwdriver or curved
tip tweezers can be used in critical situations. As seen in Figure D–3, two
corners of the PROM socket have slots for the extraction tool. These slots
can be used to extract the PROM using a small bladed screwdriver or
curved tip tweezers (reference Figures D–4 and D–5). Pry up on each of
the two extraction corners a little at a time, going back and forth to extract
the PROM evenly out of the socket.
Caution Be very careful not to crack or otherwise damage the socket! 

Replacing the CPU PROM & HART PROM
Procedure
Figure D–5.
Once the old PROM is extracted, align the new PROM on the socket so
that the beveled corner of the PROM (shown in Figure D–3) matches the
beveled corner of the socket. Push gently down on the PROM until it
snaps into place in the socket. If becomes misaligned or is hard to push,
stop and start over. Once it snaps into the socket, it is installed.
Note The 595026 PROM goes on the CPU board and the 595021
PROM goes on the HART board. While no damage will occur if the
PROMs are accidently switched, the gauge will not work. 
As can be seen in Figure D–6, the HART board is located in the middle of
the LevelPRO chassis. It is held in place with three plastic screws. At this
point, you have two options. For the first option, you can remove the three
screws using a small 90° screwdriver and remove the board from the middle
of the chassis to change the PROM. For the second option, you can use a
tool, such as the curved tip tweezers, to remove the PROM from the board
while the board is still mounted.

Figure D–7.
Once the old PROM is removed, align the new one on the socket so that
the beveled corner of the PROM (shown in Figure D–7) matches the
beveled corner of the socket. Push gently down on the PROM until it
snaps into place in the socket. If becomes misaligned or is hard to push,
stop and start over. Once it snaps into the socket, it is installed.
After installing the detector, you will need to erase memory, configure the
gauge, and calibrate as described in the main body of this manual.

CE-EMC Protection Installation
Procedure
Purpose
Procedure
To eliminate the possibility of unwanted electromagnetic signals either
going from Thermo Scientific equipment into the customer’s equipment or
from the customer’s equipment into the Thermo Scientific equipment and
for protection from high voltage spikes caused by lightning, an EMC
protection system has been developed for the Thermo Scientific LevelPRO
gauges. This procedure provides the necessary information and instruction
to perform installation of the EMC protection system properly.
The EMC protection kit comes in four configurations:




DC power without FOUNDATION fieldbus, p/n 886792
DC power with FOUNDATION fieldbus, p/n 886793 (see note at
end of procedure)
AC power without FOUNDATION fieldbus, p/n 886794
AC power with FOUNDATION fieldbus, p/n 886795 (see note at
end of procedure)
The installation is the same for all four kits, except for the addition of the
new AC power supply board.
As shown in Figure E–1 and Figure E–2 below, the DC kit comes with the
following:

An explosion proof housing for the EMC protection board

The EMC protection board installed in explosion proof housing

CE-EMC Protection Installation Procedure
Procedure
The EMC protection board wires are run through the connection fittings
at the factory so that the cable gland between the EMC board housing and
the detector housing could be factory sealed. There are 14 wires in total:
two for DC power and 12 for input/output or communication wiring.

1. Mount the bracket assembly to the detector housing. Make sure the flat
mounting plate for the EMC board housing is on the same side of the
detector housing that has the conduit fitting that is perpendicular to
the mounting tabs of the detector housing.
2. Remove the lid of the detector housing and run the EMC protection
board wires through the conduit fitting on the housing.
3. Apply the thread sealant supplied with the kit to the fitting threads of
the EMC assembly.
Caution The thread sealant used must be the same as what is supplied
with the kit. 

4. Using the appropriate tool, screw the EMC assembly onto the detector
housing approximately six to seven rotations (see note) until the
connection is tight and the mounting holes of the EMC board housing
align with the holes in the mounting plate of the bracket assembly. Be
sure to rotate the wires that are inserted into the detector housing as the
EMC assembly is rotated to keep from damaging the wires.
Note In order to maintain area protection, a minimum engagement of
five threads is required. 
5. Due to variances in components, extra nuts and washers have been
included in the kit to use as spacers between the EMC board enclosure
and the mounting plate. When the EMC assembly conduit fitting is
threaded into the detector housing so that the connection is secure, use
the extra nuts and washers to fill in any gap that may still exist and
tighten the mounting bolts.
A completed installation on the LevelPRO housing is shown below.

Replacement
If this is an AC kit, it will include a new AC power supply that must be
installed on the detector. To do this:
1. Remove the detector assembly from the housing, unplug the cable at
the bottom of the PCB going to the CPU board and remove the four
screws holding the power supply to the detector chassis (shown in
Figure E–5).
2. Install the new power supply (p/n 886783) onto the detector chassis,
using the four screws removed earlier (shown in Figure E–6).
3. Install the detector back into the housing.

Wiring
The connections shown in Figure E–8 are listed below:





The connections on the J4 connector are to be wired to the
detector.
The connections on the J3 connector are to be wired to the
customer’s system.
J1 is for incoming 24 Vdc power.
J2 is for the filtered 24 Vdc power to go to the detector (if the
detector is DC powered).
J5 must be connected to Earth Ground.
Warning Do not exceed the voltage limitations of the individual
connections or damage will occur to the EMC protection board. 
Note There must be less than 1 ohm resistance from the J5 terminal to
true earth ground. 
The J2 connector has been wired at the factory with two 18 gauge wires,
which should only be used only for a 24 Vdc output if the detector is DC
powered. The RED wire is for positive side of the 24 Vdc input and the
BLACK wire is for the negative side of the 24 Vdc output.
The J4 connector has been wired at the factory with twelve 22 gauge wires,
which should be used only for signal wiring such as RS232, RS485, 4–20
mA current output, and 9723 local display. Connections 1 through 4 are
limited to 9 Vdc, connections 5 through 8 are limited to 20 Vdc, and
connections 9 through 12 are limited to 36 Vdc.
The wiring color code for the factory installed signal cable is as follows:

Figure E–9. Detector wires
Note Any wires that are not used should be taped off to avoid shorting out
the detector. (It is recommended that you do NOT cut the unused wires,
as you may need them in the future.) 
Note The above figure shows the wires running into the enclosure. Actual
connections are not shown as they will vary. The figure is for reference
only. 
Due to the voltage limitations of the individual terminals, the RS485, the
9723 local display, the RTD input, and the contact closure inputs can be
on any of the 12 terminals. The RS232 can be on terminals 5 through 12,
and the 4–20 mA current output and input must be on terminals 9
through 12.
Note If the FOUNDATION fieldbus option has been selected, the fieldbus
output must be run on terminals 1 and 2 of J3 and J4 for the fieldbus to
operate properly. 
