About the AiRanger XPL Plus
The AiRanger XPL Plus is to be used only in the manner outlined in this instruction
manual.
The XPL Plus is a microprocessor based level monitor designed specifically for bulk
solids and liquid level measurement applications. An XPL Plus level monitor, utilizing a
single Siemens Milltronics ultrasonic transducer, accurately monitors vessel material
level without material contact. By using an additional transducer for each vessel, the XPL
Plus can monitor the material level in up to 10 vessels.
The XPL Plus transmits electronic pulses to each scanned ultrasonic transducer. The
transducer converts the electronic pulses to ultrasonic pulses which are emitted from the
transducer face in a narrow beam. The XPL Plus measures the time from the pulse
emission, to receiving the reflection (echo) from the material. Using the time measured,
the XPL Plus calculates the distance from the transducer face to the material.
mmmmm
The distance calculation is dependent upon the sound velocity within the vessel. When
Siemens Milltronics ultrasonic/temperature transducers are used, variable air
Introduction
temperatures are independently compensated for each vessel. For superior air
temperature compensation, a TIB-9 card may be used with individual Siemens Milltronics
TS-3 temperature sensors for each vessel. A simple calibration feature compensates for
homogeneous (consistent composition) atmospheres other than air.

The XPL Plus is capable of monitoring wheat in 60 m (200 ft) high silos, acetone in 45
gallon barrels, or almost anything in between, in any combination. (Ensure the transducer
selected for each vessel suits the material and measurement range required).
This material and measurement range versatility is accomplished by utilizing Siemens
Milltronics patented Sonic Intelligence®. Sonic Intelligence provides high measurement
reliability, regardless of changing conditions within the vessel monitored.
Page 2 AiRanger XPL Plus – INSTRUCTION MANUAL 7ML19981AN02
Page 7
By utilizing ultrasonic echo ranging principles with Sonic Intelligence and velocity
compensation, the XPL Plus provides outstanding measurement accuracy, usually within
0.25% of range.
The distance calculation may be converted to space, material level, material volume, or
remaining vessel capacity Readings. The Reading chosen (and operating data) for each
vessel is displayed on the Liquid Crystal Display (LCD).
Up to three Siemens Milltronics Peripherals may be connected to the XPL Plus. The AO10, SAM-20 and/or BIC-II, respectively provide analog output , relays, and RS-232 or RS422 communication interface, as programmed by the XPL Plus.
With the addition of a Siemens Milltronics SmartLinx protocol specific ‘plug in’
communications module, the XPL Plus is compatible with popular industrial control
system standards.

Perform a Master Reset (P999) if the XPL Plus was "bench tested" using arbitrary
Parameter Values before system installation, following an EPROM replacement, or
whenever complete reprogramming is required.
Special Parameters
Some Parameter Values are for display purposes only and cannot be operator altered.
These are referred to as view only parameters. In the parameters sections of this
instruction manual, view only parameters are identified by a "(V)" beside the Parameter
Number.
mmmmm
Some Parameter Values must be common for all Point Numbers. These are referred to as
global parameters. When a global parameter is accessed, the Point Number display
automatically switches to Point Number 00, and returns to the Point Number previously
selected when a non-global parameter is accessed. In the parameters sections of this
manual, global parameters are identified by a "(G)" beside the Parameter Number.
Programming Security
All operator programming is retained in non-volatile memory, immune to power
interruptions. When programming is complete, the programmer may be removed and
locked away to prevent inadvertent programming alteration. The Lock (P000) parameter
may also be used.
Security Parameter

Enhancement Parameters
When set for "maximum verification" or "material agitator", a new measurement
outside of the Echo Lock Window (P713), must meet the sampling criterion
(P712).
For " total lock ", Echo Lock Window (P713) is preset to "0". The XPL Plus
continuously searches for the best echo according to the algorithm chosen
(P820). If the selected echo is within the window, the window is then centered
about the echo. If not, the window widens with each successive shot until the
selected echo is within the window. The window then returns to its normal
width.
When Echo Lock is "off", the XPL Plus responds immediately to a new
measurement as restricted by the Max Fill / Empty Rate (P700 / P701); however,
measurement reliability is affected.

A new reading will not be validated unless 5 consecutive measurements higher
or 2 consecutive measurements lower than the current readings occur.
values:x.y x= # of ‘above’ echoes y = # of ‘below’ echoes
Resetting P711 returns P712 to the respective preset values.
P713 ECHO LOCK WINDOW
Use this feature to adjust the new measurement change permitted before Echo
Lock is applied.
The Echo Lock Window is a "time window" (in msec) placed about the echo used
to derive the Reading. When a new measurement falls within the window, the
mmmmm
window is recentered and the new Reading is calculated. Otherwise, the new
measurement is verified by Echo Lock (P711) before the XPL Plus updates the
Reading.
Enhancement Parameters
When "0" is entered (preset), the window is automatically calculated based on
the Max Fill / Empty Rate (P700 / 701). This calculation is automatically performed
when Measurement Response (P003) is altered. See Measurement Response.
For slower Measurement Response (P003) values the calculated Echo Lock
Window is narrow. For faster values the window becomes increasingly wider,

display becomes the TVT Curve Pointer.
The TVT curve is divided into 40 breakpoints, accessible by enabling the point
number as the breakpoint index field. Each breakpoint is normalized to a value of
0, as displayed in the parameter value field. By changing the breakpoint value,
up or down, the intensity of the bias applied to that breakpoint of the curve is
respectively changed. By changing the value of adjacent breakpoints, the
effective bias to the shaper can be broadened to suit the desired correction. In
the case of multiple false echoes, shaping can be applied along different points
of the curve. Shaping should be applied sparingly in order to avoid missing the
true echo.

Technical Reference
Transmit Pulse
The XPL Plus transmit pulse consists of one or more electrical "shot" pulses, which are
supplied to the scanning relays. The scanning relays are activated as required, to supply
the transmit pulse to the appropriate transducer connected to the XPL Plus terminals.
The transducer fires an acoustic "shot" for each electrical pulse supplied. After each shot
echo
is fired, sufficient time is provided for
applicable) shot is fired. After all shots of the transmit pulse are fired, the resultant
echoes are processed.
The transmit pulse shot number, frequency, duration, delay, and associated measurement
range are defined by parameters P803 and P840 to P852.
Echo Processing
Echo processing consists of echo enhancement, true echo selection, and selected echo
verification.
(shot reflection) reception, before the next (if
Echo Enhancement is achieved by
reforming
representing the echo signal received).
True echo selection is achieved by establishing the criteria which a portion of the echo
profile must meet to be considered the
Insignificant portions of the echo profile outside of the measurement range (Empty
Distance P006 + Range Extension P801), below the TVT Curve (P830 to P835), and less
than the Confidence Threshold (P804) and Short Shot Floor (P851) are automatically
disregarded.
The remaining portions of the Echo Profile are evaluated using the Algorithm(s) (P820)
and Short Shot Bias (P850) programmed. When a combination of Algorithms are used,
the portion of the Echo Profile providing the best averaged Echo Confidence (P805), is
selected as the true echo.
True echo verification is automatically achieved by comparing the position (relation in
time after transmit) of the "new" echo to the previously accepted echo position.
If the new echo is within the Echo Lock Window ( P713 ), the new echo is accepted and
displayed, and SAM-20 relays and AO-10 mA outputs are updated as restricted by the
Fuzz Filter ( P710 ) and Rate Parameters ( P700 to P703 ). If the new echo is outside of the

Distance Calculation
To calculate the "round trip" transducer to material level (object) distance, the
transmission medium
transmission to reception time period. This result is divided by 2 to calculate the "one way"
distance.
The Reading Value displayed is the result of performing any additional modification to the
calculated distance (Operation P001, Units P-005, Volume Conversion, P050 to P054,
Reading Value, P060 to P063.)
(atmosphere) sound velocity (P653) is multiplied by the acoustic
Distance = Sound Velocity x Time
2
Sound Velocity
The sound velocity of the transmission medium is affected by the type, temperature, and
vapour pressure of the gas or vapour present. As preset, the XPL Plus assumes the
vessel atmosphere is air at 20°C (68°F). Unless altered, the sound velocity used for the
distance calculation is 344.1 m/s (1129 ft/s).
Variable air temperature is automatically compensated when a Siemens Milltronics
ultrasonic / temperature transducer is used. If the transducer(s) are exposed to direct
mmmmm
Technical Reference
sunlight, TS-3 temperature sensor(s) should be used.
Also, if the temperature varies between the transducer face and the object monitored, a
TS-3 temperature sensor, mounted near the material surface (solids) or submerged
(liquids), should be used in combination with the ultrasonic/temperature transducer. Then
when Temp Source, (P660) is set for "both", the transducer and TS-3 temperature
measurements are averaged.
If the air temperature within all vessels is identical, a single TS-3 temperature sensor may
be used to represent the temperature of all vessels if Temp Source (P660) is set to Temp
Sensor # 1.
Atmosphere composition other than air can pose a challenge for ultrasonic level
measurement. However, excellent results may be obtained if the atmosphere is

performing a Sound Velocity Calibration (P651).
The XPL Plus automatic temperature compensation is based on the sound velocity /
temperature characteristics of air and may not be suitable for other atmospheres. If the
atmosphere temperature is variable, frequent Sound Velocity Calibrations may be
required to maintain optimum measurement accuracy.
Sound Velocity calibration frequency may be determined with experience. If the sound
velocity in several vessels is always similar, future calibrations may be performed on one
of the vessels and the resultant Velocity (P653) entered directly for the other vessels.
If the sound velocity of a vessel atmosphere is found to be repeatable at specific
temperatures, a chart or curve may be developed. Then, rather than performing a Sound
Velocity Calibration each time the vessel temperature changes significantly, the
anticipated Velocity (P653) may be entered directly.
(well mixed), at a fixed temperature, and consistent vapour pressure, by
Scanning
When echo processing is complete, (if more than one vessel is monitored) the scanning
relay changes state to supply the transmit pulse to the next transducer to be scanned,
after the Scan Delay (P727).
Scan Delay is automatically set by Measurement Response (P003). When high speed
scanning is required (sometimes the case for equipment position monitoring), the Scan
Delay may be reduced. Reduce the Scan Delay only as required, otherwise premature
scanning relay fatigue could occur.
All vessels are scanned sequentially unless a Point Number is "on priority" (see Smart
Scan, P720). If #1 of four vessels is on priority, the scanning sequence is 1,2,1,3,1,4,1,2,1,3,1,4
and so on.
Volume Calculation
The XPL Plus provides a variety of volume calculation features (P050 to P055).
If the vessel to be monitored does not match any of the eight preset Tank Shape
calculations, a Universal Volume calculation may be used. Use the level / volume graph or
chart provided by the vessel fabricator (or create one based on the vessel dimensions).
From this graph, determine which Universal Volume calculation will provide the best
results, and select the level vs volume breakpoints to be entered (32 max.). Generally, the
more breakpoints entered, the greater the volume calculation accuracy.

curve. This option provides best results if the curve has sharp angles joining relatively
linear sections.

Enter a Level Breakpoint at each point where the level/volume curve bends sharply (two

For combination curves (mostly linear but include one or more arcs), ensure numerous
breakpoints are entered along the arc, for best volume calculation accuracy.

This volume calculation creates a cubic spline approximation of the level/volume curve.
This option provides best results if the curve is non-linear, and there are no sharp angles.

Select at least enough breakpoints from the curve to satisfy the following:

• two breakpoints very near the minimum level
• one breakpoint at the tangent points of each arc

For combination curves, ensure at least two breakpoints are entered immediately before
and after any sharp angle (as well as one breakpoint exactly at the angle) on the curve.

The XPL Plus Measurement Response (P003) to material level change is designed to
exceed the most demanding installation requirements.

This is the most common application of the XPL Plus level monitor.
For this example we’ll assume the following:
• one 30 m high cement silo is to be monitored.
• the maximum vessel filling rate is 0.08 m per minute.
• alarm indicators are required when the cement level exceeds 25 m or falls below
10 m.
• filling equipment is to be automatically deactivated at 27 m.
• in the event of a measurement difficulty, failsafe operation is to be activated in 2
minutes.
• if the difficulty doesn’t subside, the filling process is to be stopped before a spill
occurs.
• an XLT-30 transducer is mounted with its face flush with the top of the vessel.
• a TS-3 temperature sensor is connected to the Temp Sensor 1 terminals.
• a SAM-20 is connected as BANK 1 to the Peripheral Communications terminals.

P104 Lo Lo Alarm Enter "5" for Lo Lo Alarm at 5.000 m.
With process control equipment disabled, enter the RUN mode to monitor system
performance and alarm programming. Otherwise, perform a Reading Measurement
simulation (P920).
When satisfied with system performance and programming:
• connect a high alarm indicator to SAM-20 Relay # 1 (see P100 = 3).
• connect a low alarm indicator to SAM-20 Relay # 6.
• connect a high high alarm indicator and filling equipment stop/start control to
SAM-20 Relay # 11.
• connect a low low alarm indicator to SAM-20 Relay # 16.
(Note that SAM-20 relays are de-energized in "alarm" conditions).
When monitoring dusty dry solids, measurement difficulties may be encountered,
(especially when pneumatic filling equipment is used). For this example (assume the
maximum filling rate), failsafe operates as follows.
e.g. 09:15 am Echo lost at 6.00 m, low alarm is still on, failsafe countdown begins.
09:17 am Failsafe activated, actual level = 6.16 m, reported level = 6.00 m.
09:57 am Low alarm off, actual level = 9.36 m, reported level = 10.00 m.
12:27 pm High alarm on, actual level = 21.36 m, reported level = 25.00 m.
12:47 pm Infeed stopped, actual level = 22.96,reported level = 27.00 m.
Technical Reference
mmmmm
When the dust settles (and the echo is regained) the reported level advances
toward the actual level. When the reported level reaches 25.55 m (5% of Span
less than the high high alarm trip point), the high high alarm goes off, restarting
the infeed and filling the vessel to 27.00 m.

discharge outlets.
• the maximum filling/discharge rate for each bunker section is 3 inches per
minute.
• an XLS-30 transducer is mounted 65 ft above each discharge outltet.
• a mA output proportional to each bunker section material level is required by the
PLC.
• a mA output proportional to the average material level is required for total
material calculation.
• if a measurement difficulty occurs for greater than 2 minutes, 3.8 mA is required
by the PLC.
• the XLS-30’s are connected to the Transducer 1 to Transducer 6 terminals.
• an AO-10 is connected to the XPL Plus Peripheral Communications Terminals.

When satisfied with system performance and programming:
• connect the AO-10 mA outputs 1 - 6 to the PLC as required.
• connect the AO-10 mA output 7 to the device indicating total material.
Note that on XPL Plus "power off" the AO-10 mA output is "held" and on AO-10 "power off"
the mA output drops to 0.00 mA. During a power interruption, the "last known" mA output
value is maintained in memory for 1 hour minimum. If power is interrupted beyond 1 hour,
on power resumption, the mA output immediately assumes the "new value".
Note: If a Tripper Car is used to fill each section of the bunker, see Example 4 as well.

Example 4 - Distance Measurement
This mode of operation may be used for equipment position monitoring up to 60 m (200 ft).
Operation is similar to Space Measurement operation except that measurements are
referenced to the transducer face.
For this example we’ll assume the following:
• Transducer 10 (an XLS-60) is mounted horizontally* facing the Tripper Car.
• when the Tripper Car is at the far end stop, the transducer face to Tripper Car
distance is 175 ft.
• when the Tripper Car is at the near end stop, the transducer face to Tripper Car
distance is 5 ft.
• the Tripper Car travels at 7 ft/min, and is normally maintained 14 ft from either
end stop.
• a mA output proportional to Tripper Car distance from the transducer is required
for PLC operation.
• if the PLC reads 3.8 mA, the Tripper Car is to immediately stop.
• an AO-10 is connected to the XPL Plus Peripheral Communications terminals.
*When an XLS or XLT series transducer is mounted horizontally, install a support plate
under the transducer to prevent possible mounting/conduit connection damage.

With the PLC disabled, enter the RUN mode (or perform a Reading Simulation, P920).
When satisfied with system performance and programming, connect AO-10 mA Output 10
to the PLC.
For a completely automated system, position the Tripper Car via the PLC, based upon
bunker material level, as monitored by the remaining XPL Plus Point Numbers. (See
EXAMPLE 3 - mA Multi-point Average). When both examples 3 and 4 are used, the PLC
may be programmed to operate as follows:
• fill bunker sections to predetermined levels based upon AO-10 mA output 1 - 6
values.
mmmmm
• shuttle Tripper Car to lowest bunker section level.
• if a bunker section "LOE" occurs (3.8 mA), shuttle to the next lowest bunker
section.
• if a Tripper Car "LOE" occurs (3.8 mA on mA Output 10), stop Tripper Car and

material feed.
• when "LOE" subsides, restart material feed.
• when all bunker levels are full, stop material feed and "park" the Tripper Car.
Application Assistance
The preceding examples describe only a few ways in which the XPL Plus can be applied
to process measurement requirements.
Page 92 AiRanger XPL Plus – INSTRUCTION MANUAL 7ML19981AN02
Page 97
The XPL Plus can be used to monitor almost any process (within the temperature,
measurement range, and chemical immunity capabilities of the system) where a distance
measurement or determination of presence vs. lack of presence of an object is desired.
By thoroughly reviewing the PARAMETERS sections, you may identify some interesting
ways of using the XPL Plus to monitor specific processes.
e.g. 1 In a paper mill, one transducer may be used to monitor roll diameter, while another
monitors the presence of paper to the roll. The feed can be stopped based on the roll
diameter or a paper break. e.g. 2 For a truck loading station, one transducer can monitor
truck position while another monitors load height. The discharge can be stopped if
the truck is out of position or when it’s full, and the discharge chute can be
positioned a minimal distance from the load during filling to keep dust down.
Siemens Milltronics has many years experience applying ultrasonic level measurement
to a variety of processes in the mining, aggregate, lumber, grain, chemical, pulp and
paper, water, and waste water industries.
If you encounter a difficulty applying the XPL Plus to a process measurement
requirement, or successfully apply the XPL Plus to a "unique process" we may have never
considered, contact Siemens Milltronics or your local distributor.
BIC-II Support
As preset, the XPL Plus provides a digital output via the
mA bipolar serial current loop) terminals, capable of supporting the Siemens Milltronics
BIC-II.
The XPL Plus utilizes
simplex convention
communication protocol. Data messages are
continuously transmitted at regular intervals (no poll is required) at 4800 baud. All data is
transmitted in structured messages of ASCII characters consisting of eight data bits, no
parity, and one stop bit.
If Peripheral Communications (P740) is set for "formatted" messages, a comma is inserted
between each message field (except immediately preceding the "End of Message"
characters).

Maintenance
The XPL Plus should require no maintenance, though good housekeeping practices in
and around the area of the enclosure are recommended.
Wipe out the area of the enclosure lid docking bay recess with a clean dry cloth (if
necessary) before installing the programmer.
Transducer inspection, to verify the effectiveness of the self cleaning design, is
recommended. If material build-up on the transducer face is observed, to maintain
maximum system performance, a schedule of regular cleaning should be adopted.
