Basic Concepts
Communications
The Ronan X96S Weigh Scale provides both 4-20 mA current loop and HART communications.
4-20 MA
For many years, the field communication standard for process automation equipment has been a 4-20 mA current loop signal. The
current varies in proportion to the process variable being represented. In typical applications, a signal of 4mA will correspond to
the lower limit (0%) of the calibrated range and 20mA will correspond to the upper limit (100%) of the calibrated range. Thus, if
the system is calibrated for 0 to 4 pound per foot, then an analog current of 12mA (50% of range) will correspond to a weight of 2
pounds per foot.
HART
HART Field Communications Protocol extends the 4-20mA current loop standard to enhance communication with smart field
instruments. The HART protocol was designed specifically for use with intelligent measurement and control instruments which
traditionally communicate using 4-20mA analog signals. HART preserves the 4-20mA signal and enables two-way digital
communications to occur without disturbing the integrity of the 4-20mA signal. Unlike other digital communication technologies,
the HART protocol maintains compatibility with existing 4-20mA systems, and in doing so, provides users with a backward
compatible solution. HART Communication Protocol is well established as the "de facto" industry standard for digitally enhanced
4-20mA field communication.
The enhanced communications capability of intelligent field instruments employing the HART protocol, offers significantly
greater functionality and improved performance over traditional 4-20mA analog devices. The HART protocol permits the process
variable to continue to be transmitted by the 4-20mA analog signal and additional information pertaining to other variables,
parameters, device configuration, calibration, and device diagnostics to be transmitted digitally at the same time. Thus, a wealth
of additional information related to plant operation is available to central control or monitoring systems through HART
communications.
Variables
There are three types of variables, communications variables, device variables and configuration variables.
Communication Variables
HART defines four communication variables, PV (Primary Variable), SV (Secondary Variable), TV (Tertiary), and QV
(Quaternary). PV is assigned to the primary 4-20 ma loop . HART is also communicated over this loop. SV is assigned to an
optional secondary 4-20 ma loop.
Device Variables
The Ronan X96S Weigh scale has 4 device variables:

Theory
Theory of Radiation Gaging
Radiation gages operate on the principle of radiation absorption and transmission.
A beam of gamma radiation is directed from the source holder, through the process material and the belt, and onto the surface of
the detector.
Radiation which is not absorbed by the material through which it passes, is transmitted to the surface of the detector.
Process measurement is possible because the amount of radiation absorbed and transmitted is predictable.
The absorbed radiation is directly related to the weight of process material in/on the conveyor while the transmitted radiation is
inversely related to the weight of process material on the belt.
Therefore, an increased process weight results in a decrease of transmitted radiation.
Since the radiation that's not being absorbed is being transmitted, the process weight can be inferred by measuring the amount of
radiation reaching the detector at any point in time. The detector's output signal, in counts, also varies inversely to the process
weight.
When the process weight is low the detector is exposed to a maximum amount of radiation which produces a HIGH output of
counts. When the process weight is high the process material "shields" the detector and prevents radiation from reaching the
detector, producing a LOW output of counts.
The X96S Microprocessor converts the detector signal to user's measurement units of weight: lb/ft, oz/ft, kg/m, g/mt, and rate:
STon/h, Lton/h, lb/min, oz/min, MetTon/h, kg/h, kg/min.
The X96S displays the output measurement range in the selected user units. The "zero" of the measurement range represents the
lowest weight of interest, while the "span" of the measurement range represents the highest weight of interest.
Reduction of the signal "noise" due to radiation statistics is handled in the stage of signal processing known as digital filtering.
Digital filtering is a form of statistical averaging used to smooth, or dampen, random radiation as well as process-related noise.
Increasing the digital filter’s “time constant” decreases signal noise.
Dynamic tracking permits the gage response to temporarily by-pass the digital filter. This is helpful in some processes where
sudden or drastic step changes in process must be observed in their true, or unfiltered, state.
Software also compensates for the decay of the radioactive source activity. On-going adjustments are made automatically for the
rate of decay, or source half-life.
4
Principles of Operation
The detector's raw output signal is processed through several stages of software in the X96S.
Some of the more significant stages of signal processing are:
• Units Conversion – conversion of counts into user-selected weight units
• Measurement Range – 4-20 mA output defined by the user-selected range in user-selected units.
• Digital Filtering – signal smoothing to reduce statistical radiation noise
• Dynamic Tracking – quick gage response to quick process changes.
• Source Decay Compensation – automatic compensation for the radioisotope decay
• Calibration (Referencing) – calibration of gage to user process.
The Calibration (and Referencing) procedure relates detector output (in counts) to numeric values that accurately represent the
actual process weight.
The weight algorithm (or curve) used by the X96S software is a logrithmic function. That is, the relationship between the
detector output and the process mass denisty is mathematically expressed as:
Rc = R0 + Ln( Io ) × ( 1 ) × a

FUNCTION
Shows the current state of the dynamic tracking filter (enabled or disabled) and allows
the user to change the state. If disabled the filter uses only the Slow Time Constant.
Shows the (sigma) multiplier used to determine maximum number of raw counts
variation (for scintillation) or raw analog value (for ion chamber) that the input can
vary from the current filtered counts before changing to the dynamic filter. Sigma is
the square root of the current filtered counts. Also allows user to change this number.
Fast Time Constant value to be used when the Fast Counter reaches zero.
Shows the fast count down counter value. If gauge has been in dynamic tracking long
enough to be using Medium filter and the raw counts continued to exceed the sigma
value, the fast counter value is decreased each consecutive scan. The Fast counter
value resets and returns back to the original value if the raw counts do not continue to
exceed the sigma value. Once the Fast TC is triggered, it will continue to be used until
the counts are within the sigma value for the Fast counter number of times
consecutively. Also allows user to change this number.
Medium Time Constant value to be used when the Slow Counter reaches zero.
Shows the slow count down counter value. If gauge is in dynamic tracking, and the
raw counts continued to exceed the sigma value, the slow counter value is decreased
each consecutive scan. The Slow counter value resets and returns back to the original
value if the raw counts do not continue to exceed the sigma value. Also allows user to
change this number.
Slow Time Constant value to be used if the the Slow Counter has not reached zero.
Shows the maximum number of potentially erroneous measurements in a row to
bridge before deciding that a step change has occurred in the weight value. Also it
allows user to change this number. Erroneous measurement is define when the raw
signal is 4 times the pre-selected sigma multiplier by the user.
Shows the current state of the filtering mechanism.

The X96S Local Display consists of a 16 line by 21 character
display and a 10 key keypad. The top line of the display is
reserved for the analog bar, if enabled. The next line is used for
the Ronan logo. Line #3 shows the device model line. Line #4
displays the specific screen title. That title is typically a screen
description or required action. The remainder of the lines, with the
exception of the last line, are screen or action dependent. The last
line displays the active function keys labels.

Directly beneath the display is a keypad. The keypad is divided
into two parts:
• a 4 key function key section and
• a 6 key (2 rows of 3 keys) cursor control section
C
Navigating Menus
The menu and the display screen are one or more lines, each consisting of a line label (name of the entry) and optional
value and units. In most cases the menu navigation is exactly following the Rosemount 275 Configurator’s user
interface.
The first column is reserved for direction keys if the number of lines does not fit the physical display. The second
column will show a right arrow character when the cursor is on this line and there is sub-menu or some other screen or
action assigned to this line. If the menu is not at the top level, the end of the menu title line will show left arrow to
indicate it, and to remind that the user could ‘go back’ to the previous menu by pressing left arrow.
If the line length is longer than the physical display, a right arrow will be displayed, and if the right arrow key is
pressed, the value will be displayed in a screen, similar to the editing one, but with editing disabled.
Depending on the type of the function assigned to the line a different screen will be shown when the user presses the
right arrow key.
If this line is a sub-menu, another menu opens.
31
Editing Values
The editing of different types of values is designed around the use of the four direction keys and up to 4 function keys. The left
and right arrow keys are used to position the cursor to the letter/digit to be edited, and up and down arrow keys are used to scroll
between the possible values for this position.
In all editing functions, the edited value is displayed below the current value.
Editing Fixed Point Numbers
Using left and right arrow keys, position the cursor at the desired position and scroll the digit at this position using up and down
arrow keys. When the value rolls up or down a carry/borrow occurs from the next/previous digits. When done, press F4. To
discard changes and abort, press F3.
Editing Floating Point Numbers
Using left and right arrow keys, position the cursor at the desired position and scroll the digit at this position using up and down
arrow keys. When the value rolls up or down a carry/borrow occurs from the next/previous digits. When done, press F4. To
discard changes and abort, press F3.
The difference to the fixed point editing is that the decimal point is automatically skipped when moving the cursor left or right.
Editing Text Strings
Using left and right arrow keys position the cursor at the desired position and scroll the character at this position using up and
down arrow keys. The characters are rotated between blank and ‘z’. When done, press F4. To discard changes and abort, press F3.
When the string value is a password, it always starts with * for every character to avoid seeing the password.
Editing Enumerated Values
The enumerated values are displayed as menu items below the current value. The up and down arrow keys are used to select the
desired choice, and F4 is used to confirm it. F3 is used to abort the editing and leave the value unchanged.
X96 Local Display Vs 275 Calibrator
The local display user interface is very similar to the 275 Calibrator, but there are some differences. One of the major ones is the
fact that the X96 local display lacks a numeric keypad. This automatically means that the shortcuts are not supported, as also the
value editing is done using only the cursor keys.
Another difference is the fact that all values in the local display are immediately updated, and there is no need to use SEND action
whenever a value is changed. Also, the flashing ‘heart’ character indicating that the configurator is exchanging data through
HART communication is not needed and thus not presented on the local display.
When there is a value to be displayed and the line length doesn’t fit the display, the 275 Configurator displays the label only and
lets the user see the value using the right arrow key. X96 local display will display whatever could fit the display, thus indicating
to the user that there is more to be displayed and the right arrow sign is not indicating a new menu.

Calibration
Initial calibration consists of two parts, the belt speed calibration and the mass density calibration.
The belt speed calibration correlates the speed signal to the rate the material is moving. For weigh scale
using an encoder or tachometer this is achieved by stopping the belt and calibrating the minimum speed and
running the belt at full speed and calibrating the maximum. (If the weigh scale uses line down contact,
calibration requires only entering the belt speed through the keypad, no calibration is required.)
Speed Low and High Calibration

Mass Density Low/Reference and High/Calibration
The mass density calibration correlates the detector counts to the mass upon belt. This can be achieved by
several different methods. One method consists of Referencing on Empty Belt. The next step requires
running predetermined weights past the gauge and comparing the indicated weight to the actual weight. For
alternative calibration methods, consult Ronan Engineering.
First you will REFERENCE the system on an Empty Belt. Then you will CALIBRATE the system by one
of the following means, 1) passing or catching a known amount of material through the scale, 2) placing a
static load on the belt that you must weigh or 3) inserting an Absorber Plate of a predetermined value in the
absorber guide (usually located in front of the source holder).

You must proceed to High Calibration to complete the calibration.
42
High Calibrate
PROCEDURE (Option 1)
Passing or collecting a known amount of material through the scale and manually entering the L.F.
value(Loading Factor)). Initially (if you are first commissioning the gauge) you should start off the L.F.
value with the active detector length (in feet). You will want to make sure you run at least a 30 minute load
through the scale to get an accurate calibration. This is achieved by first zeroing the totalizer. Next, you
pass the known amount of weight past the Ronan X96S weigh scale. You then calculate the new L.F. (Load
Factor) by comparing the measured weight to the actual weight. You enter the new calculated value into the
X96S microprocessor. You should run two to three more test loads and make sure the Ronan Weigh Scale
is within the accuracy of the scale. (See original quote to determine the accuracy of your scale to your
application).

44
High Calibrate (Continued)
PROCEDURE (Option 2)
Placing a static load on the belt that you must weigh):
Before proceeding, ensure that the belt is loaded with an up-scale loading at least 75% of maximum full
scale loading. The up-scale loading may be obtained by placing a static load onto a stopped conveyor,
in the radiation beam. The loading in lbs/ft is obtained by taking the through-put in lbs/min and dividing
by the speed (ft/min). The static loading should be a spread of material that covers at least two linear ft. of
conveyor e.g., if the desired calibration loading is 20 lbs/ft, 2 ft. of loading is 40 lbs. The calibration is to be
done with product spread evenly over the conveyor shaped to the natural slump of the product. The value of
the calibration loading is assigned to the calibration after the gage output is read on the measured material.

displayed value is correct, press the F4 key (Enter). ). The High Calibrate is complete.
The Mass Density Calibration is complete.
45
High Calibrate (Continued)
PROCEDURE (Option 3)
An alternative to calibrating with process material is to use an absorber plate. The procedure is much the
same as that used for a process calibration, the only difference is that instead of material being placed on the
belt, the equivalent absorber plate is inserted into the space provided and the value assigned to the plate is
used as the calibration value. This value is determined after the scale has been commissioned on process.
Once the weigh scale has been calibrated by option 1 or 2, the conveyor is then run emptied and the
absorber plate is inserted into the space provided. The value displayed from the X96S Weight (lb/ft) is
recorded and also is marked on the absorber plate. This value will be the absorber equivalent weight.
Insert the absorber plate into the space provided. Run the conveyor empty at normal operating speed
during the high calibration.

Once the high calibration is finished, do not forget to remove the absorber plate. Make sure you store
away the absorber plate for future calibration.
The High Calibrate is complete.
The Mass Density Calibration is complete.
46
For future reference, document these items:
(a) Environmental/process conditions (densities, temperatures, etc.) that influence the reference/
calibration. The next time a calibration is performed, you will need to duplicate the conditions, or account
for the differences.
(b) All changes made to factory-default settings such as time constant, reference constants (loading
factor),, etc.
(c) A record of "counts" being received from the detector may assist with future troubleshooting efforts.
47
Configuration
Ronan ships the Weight Scale System with factory-default software settings. Those settings are responsible for the information
that initially appears on the status displays.
After installation at your site, you may need to reconfigure the system to fit your application. The goal is to correlate the X96S
output with your actual weight readings. The list below summarizes the activities that are detailed in the remainder of this
chapter:
-
Check the factory-default settings to be sure they are appropriate for your circumstances. IF NOT, make the necessary
changes and document those changes for future reference.
Perform an initial calibration to correlate the X96S’s output to the actual process rate/weight
Document detector output counts at calibrated values to assist in troubleshooting. Also, record changes you make to factorydefault settings. Keep this information for future reference.
48
Detector
Scintillator Detector
Description
The Ronan scintillation detector consists of three main components: The
plastic scintillation crystal, the photomultiplier tube (PMT), and the
associated electronics.
Scintillation Crystal
The crystal used for the Weigh System is poly vinyl toluene (PVT) plastic.
The crystal produces light pulses which are proportional to the incident
radiation events striking it.
Typically mounted in a stainless steel shell the entire crystal assembly is
sealed against moisture and dirt and is non-repairable. An integral flange
serves to mount the crystal to the PMT. A special silicone membrane
serves as an optical coupling medium between the crystal and the PMT.
Photomultiplier Tube
The PMT is a light sensitive vacuum tube with a photosensitive layer that
converts the light pulses to an electrical current. Light pulses from the
crystal strike the photosensitive layer and release electrons. A high voltage
power supply connected to the photosensitive layer accelerates the
electrons through stages of current amplification.
The PMT and its associated components are housed in a special magnetic
shield. The tube is shock-mounted internally, with an interface plate at the
top, which also mounts the electronics and the outer shell.
____________________________________________
Electronics
Two to four boards (depending on the scintillator type, housed in a stainless
steel shell, comprise the electronics and their functions.
• High Voltage Power Supply
• Preamplifier
• Discriminator
• Pulse Output
49
Detector Service
The critical components of the electronic circuit and the
PMT/Crystal Assembly are aligned before leaving the
factory. If any component of the Scintillation Detector is
adjusted or replaced, the performance of the entire system
will be adversely affected and will require realignment
before continued use is possible.
Therefore, the scintillation detector IS NOT field
serviceable. Should a problem arise with the detector, the
entire Detector Assembly should be returned to Ronan for
repair/replacement.
50
ION Chamber
Detector/Amplifier
Assembly
(DET-7471-XXX)
Ronan’s ion chamber detector is filled with an inert
high-pressure gas. It uses low-voltage (-15VDC) bias
and generates a low-level current proportional to the gamma
radiation incident on the detector. The current
generated is on the order of 10 ρA, so an electrometer amplifier is
required to convert the current to a low-impedance, high level
voltage signal. The signal is then measured by the X96S
Microprocessor, which converts the voltage signal to a output of
4-20mA for a specified measuring range.
Refer to drawing B-6409-K. The current (I), generated
Circuit Description
by the ion chamber, is fed into the inverting input
terminal of the electrometer amplifieer, (IC1). The electrometer
amplifier output is filtered by R2C4 (a microphonic, low-pass
Reference:
B-6409-K filter) and fed into a follower amplifier. The output of IC2 is
B-9742-K proportionally fed back to the inverting terminal to provide a
closed-loop gain based on the value of the gain resistance
potentionmeter (R2) on the X96S input board. (B-9742-K).
The detector’s gain is adjusted whenever the signal output of the
detector is too high and may saturate the input of the X96S, which
is approximately 3.5VDC. The output must be less than 3.0VDC
with an empty vessel.
An offset zero control (R6), used to null the offset voltage of the
electrometer amplifier, is factory adjusted and glyptal coated. R6
is adjusted to make the output, (TP1), zero with Rf shorted. (TP2
is circuit common.)
The most important components of the amplifier are the
operational amplifier (IC1), feedback resistor (Rf), and feedback
capacitor (Cf). If these components are substituted, the
performance of the system will be adversely affected.
51
Servicing the Detector
The ion-chamber detector contains pressurized inert gas. The ion
chamber itself is not serviceable and must be returned to the
factory for service. Instructions follow for “Detector
Removal/Replacement.”
However, a qualified technician can troubleshoot and service the
detector’s amplifier assembly. Some precautions are needed
when handling the detector/amplifier assembly.
It is important to keep the interior of the detector/amplifier dry.
Moisture on the high-impedance components will cause leakage
currents. If the amplifier lid is opened, it is important to see that
warm, dry air is introduced into the amplifier before replacing
the gasket lid.
52
Detector Removal/
Replacement
1) Check NOTES below for illustrations
and cautions that apply to your specific
equipment.
2) Unscrew cap on detector housing.
3) Unscrew connector on top of detector.
4) Remove detector from housing.
5) Carefully install replacement detector in
housing.
6) Screw connector back onto detector.
7) Immediately replace detector-housing
cap.
8) Follow instruction to REFERENCE and
CALIBRATE new detector.

at a maximum of 50 ma.
24 volts DC is provided to be used as a wetting voltage when needed.
An isolated 15 volt DC power supply capable of providing 200 mA is also provided. The primary use of this power supply is to
power a quadrature encoder but can be used for other purposes if it is not required for this purpose.
X96-2009PL
X96-2009PL is the Scintiallation Detector Interface Module. This optional9 module provides:
• 1 isolated scintillation input (pulse counter, max signal 0-1210 V, threshold 0.6 V)
• 1 head temperature input (1 uA per deg K)
• 1 non-isolated RTD (3-wire) input
• isolated power for the scintillation detector 24 V 40 mA supply11.
6
When used with dry contacts, jumpers shall be used on the connector block to provide the wetting voltage. When used in this
mode, input to input isolation is not maintained.
7
When used with live contacts, each input shall be able to accept up to 30 volts DC. Zero volts to 0.8 volts are recognized as a
logic zero and 2.5 volts to 20 volts are recognized as logic one.
8
The interface to the quadrature encoder shall consist of two inputs, 15 volts DC at 200 mA (described in a later section), and
common.
9
At least one detector interface module is required.
10
8.6 V nominal.
11
The power supply has the ability to control the power to the scintillation detector:
• when commanded by the CPU module,
• when the processor on the module detects a condition that could harm the scintillation detector,
• when the watchdog timer generates a reset.
