GENERAL INFORMATION

ABOUT THIS MANUALIMPORTANT

It is essential that this manual be referred to during installation and start up of the AiRanger XPL.

The Quick Start section provides a simplified start up procedure for the AiRanger XPL. It highlights theprogrammer keypad, parameter entry, common display messages and the first eight and most commonly usedparameters; all you need to do to get the AiRanger XPL to give a measurement display.

The Applications section provides a general description of the common applications found in industry andillustrates them with examples. It is suggested that you refer to the sub-section which most suits yourapplication. The calibration may be further optimized by referring to section Parameter Description.

ABOUT THE AIRANGER XPL

The Milltronics AiRanger XPL is a ten point ultrasonic level monitoring system consisting of an AiRanger XPLin a polycarbonate enclosure, a removable programmer and a combination of up to ten ultrasonic transducersof any model. The basic system can be expanded to incorporate relays, analog outputs and computerinterface by the addition of the respective Satellite Alarm Module (SAM-20), Analog Output (AO-10) andBuffered Interface Converter (BIC) peripherals.

The AiRanger XPL emits an ultrasonic signal via the transducer. The echo is reflected from the material andreceived by the transducer. The echo is processed by the AiRanger XPL and the time at which the ultrasonicpulse hits the level or target is extracted and compared to the time at which it was sent. This time differential isthen converted into distance, material level or volume as a basis for display, relay control and analog output.

SECTION III

INSTALLATION

AIRANGER XPL

The AiRanger XPL should be mounted in an area that is: within the ambient temperature range and is suitablefor the specified enclosure. The front cover should be accessible for programming and viewing and havesufficient room to swing open.

It is advisable to keep the AiRanger XPL away from high voltage or current runs, contactors and SCR control drives.

Do not mount the AiRanger XPL in direct sunlightwithout the use of a sun shield

Refer to figure 1 for outline and mounting dimensions.

TRANSDUCERS

Wiring of transducer cable must be done in conjunction with approved conduit, boxes and fittings and to procedures in accordance with all governing regulations.

All transducer cabling must be run in grounded metal conduit for optimum noise immunity.

Refer to: figure 3, ST-25/50 Transducer Outline and Wiring

figure 4, ST-100 Transducer Outline and Wiring

figure 5, LR-21 Transducer Outline and Wiring

figure 6, LR-13 Transducer Outline and Wiring

1. Mount the transducer above the highest anticipated material level

by at least: 30 cm (1 ft) for ST-25 and ST-50 series transducers

90 cm (3 ft) for ST-100 series and LR-21 transducers

120 cm (4 ft) for LR-13

2. Install the transducer so that it will have a clear sound path perpendicular to the liquid surface (refer to figure 8 & 11), or toward the draw point at the bottom of the bin in solids applications (refer to figures 9 & 12).

3. To avoid false echoes, install the transducer such that the sound path will not intersect vessel fillspouts, rough vessel walls, ladders etc. (refer to figures 11 & 12).

PROGRAMMER

In order to calibrate the AiRanger XPL, a programmer (which has a magnetic back plate) must be set into thefront cover recess of the AiRanger XPL. It can be removed when operating in the Run mode. Be sure to keepit away from objects, such as floppy discs, that are susceptible to damage from magnetic fields. (Note: since aprogrammer need not be ordered with each unit, check your order if you think that the programmer is missing).

PL-336 3 – 1

TEMPERATURE COMPENSATION

The AiRanger XPL comes standard with temperature compensation circuitry fed by a compensation signal.This signal is generated internally either by the air temperature parameter (P-35) on a per point basis or byresponse to external air temperature as sensed by a remote temperature sensor.

If a temperature sensor is connected directly to the temperature sensor input, board B\TB1-3/4, it will representa temperature common to all points.

In order to sense the temperature at individual points, an optional Temperature Input Board (TIB-10) must bemounted on board A. Points requiring automatic temperature compensation would have their temperaturesensor connected to the AiRanger XPL via the TIB-10. The TIB-10 comes factory installed on board A or as akit for future customer installation.

TIB-10 INSTALLATION

If the TIB-10 is not installed, the following procedure should be followed.

- insure that the power to the AiRanger XPL has been removed.

- open the front cover of the AiRanger XPL

- mate the TIB-10 RC1 connector to the AiRanger XPL board A RC2 pins

- push TIB-10 down until its standoffs are seated on board A

- insert the three 4-40 x 5/8" screws provided through the TIB-10 mounting holes and standoffs, then screw them into the mating threaded inserts of board A

- note : the terminal block on the TIB-10 is a plug in type. The terminal block can be removed from the connector to facilitate wiring and then plugged back into the connector.

SECTION IV

START UP

GENERAL

The AiRanger XPL has two modes of operation: Run and Calibrate. Run is the normal mode of operationwhere readings are displayed and data is transmitted for the control of the alarm module and analog output.The Calibrate mode is used for programming the operational parameters to suit the user’s preferences andthe particular application to which the AiRanger XPL will be applied. It is also used for viewing status anddiagnostic parameters. All access to the AiRanger XPL is done via the programmer when set in the frontcover recess.

After installation procedures have been completed, the AiRanger XPL may be powered up. Upon initialpowering up, that is to say all points are out of service (P-01, points 1 to 10 = OFF), the unit will start up in theCalibrate mode with the following display prompting the user to begin programming.

On subsequent powering up, the unit will start up in Run if at least one point has been placed in service andgive a reading consistent with its programming.

The mode of operation is toggled between Run and Calibrate at the user’s need by pressing .

The first step when calibrating is to reset all parametersto their factory setting by P-99 as described in section VII

When the calibration has been completed, the AiRanger XPL can be made to simulate its operation; givingdisplay, alarms and analog output. Refer to Parameter Description\Simulation and Measurement\P-50/53.

Once satisfied that the parameters have been properly entered, the unit may be put into the Run mode.

Unsatisfactory response in the Run mode, after programming, may indicate that the transducer’s aimingrequires adjustment (especially in solids applications). Refer to figures 8 and 9.

SECTION VFUNCTIONAL

TRANSCEIVER

SCANNING

The AiRanger XPL transceiver transmits the selected combination of long (P-67) and/or short pulses (P-66) inorder to perform a measurement. A short pulse is restricted to short ranges. A short pulse echo is thus definedas an echo from a short pulse. A long pulse covers the full measurement range of the AiRanger XPL. A longpulse echo is defined as an echo from a long pulse. The range specification is as follows:

Neon lamp L1 on the board B will flash for every pulse that is transmitted. The set number of long pulses ofthe combination will be transmitted first. The transmitter pauses while the received echoes are beingprocessed before transmitting the next set of pulses. The scanning relays switch as soon as the last long orshort pulse to the selected point has been transmitted. Processing of the previous pulse series occurs whilethe scanning relays are switching and will not allow the transmitter to operate for the next point until theprocessing of the previous point has been completed. Thus the normal scanning sequence is to cycle throughall in service points, point 1 through 10.

Points are placed in service (P-01) by identifying the model of transducer associated with that point. When thecode is entered, a test pulse is transmitted to verify that the proper code has been entered and the transducermodel is displayed as a proper response. Otherwise, the display will show a message to indicate that it isunsure of the transducer or the integrity of the associated wiring or installation. This may be due a short oropen circuit in the transducer or excessive ringing due to over tightening of the transducer or temperatureextremes.

PRIORITY

If points have been given priority status, either ‘Manual’ or ‘Auto’, then the scanning cycle will proceed on twolevels. All priority points will be sequentially scanned once followed by a scan of the first non-priority point. Allpriority points will be re-scanned and then the second non-priority point will be scanned. Thus a non-prioritypoint will only be scanned once per cycle.

e.g. priority points: 1 & 3 non-priority points: 2, 4 & 5 sequence: 1 3 2 1 3 4 1 3 5 1 3 2

PL-336 5 – 1

MANUAL

Any point or set of points may be given priority status. This is done during the run mode by pressing ENTERwhen the desired point is displayed. A dot will appear in the ‘Status’ field of the point being displayed toindicate priority. Priority status is removed in the same way, as the ENTER key acts as a toggle.

AUTO

Under auto priority scanning, priority is automatically assigned to points meeting the criteria established bysetting parameter P-57. When the criteria for priority is no longer met, then the priority status is automaticallyremoved. The criteria can be any combination of the following conditions :

filling rate : if the filling rate ( P-42 / ) is greater than the filling rate limit, the point concerned is placed on priority.

emptying rate : if the emptying rate (P-42 / ) is greater than the emptying rate limit, the point concerned is placed on priorty.

L.O.E. : if a loss of echo condition occurs, the point concerned is placed on priority.

If more than one point is placed on auto priority, the priority points will be scanned in numerical order.

Auto priority will automatically cancelpoints placed on priority manually.

FREQUENCY

The transceiver section of the AiRanger XPL is located on the board B. As the transceiver operatingfrequency must match the resonant frequency of the transducer being scanned, the transmit signal will begenerated at the corresponding frequency (P-1). The receiver will be tuned, on a per point basis as well, inorder to process the receive echo.

DISPLAY

While in the Run mode, the Reading field will be periodically updated. The default display is a reading ofmeasurement (P-50). The display can be made to show other types of readings by pressing one of the dualfunction keys (refer to section Start Up\Programmer Keypad). The alternate reading will remain displayed untilanother reading is selected.

92/03/16

The display scrolls through the selected reading for the points in service. Pressing will stop/start theautomatic scrolling of the display. When the automatic scrolling is stopped, the display can be manuallyscrolled forward or reverse by pressing or key respectively. Thus the display scrolling is completelyindependent from the transducer scanning.

PL-336 5 – 2

TRANSDUCER

The transducer converts the electrical energy of the transmit pulse from the transceiver into acoustical energyand converts the acoustical energy of the echo back into electrical energy for the transceiver receive period.

The effective acoustical energy is generated from the face of the transducer and is radiated outward,decreasing in amplitude at a rate inversely proportional to the square of the distance. Maximum power isradiated axially (perpendicular) from the transducer face in a line referred to as the axis of transmission.Where power is reduced by half (-3 dB), a conical boundary defining the sound beam, centered about the axisof transmission is established. The diametric measurement of the cone in degrees defines the beam angleand varies according to the transducer type. Impedance matching techniques are used to optimize the transferof power from the transducer into air and from the air back into the transducer.

Beam angle, frequency and range are three of the more prominent characteristics of concern when choosing atransducer for an application. The AiRanger XPL is designed to work with any combination of the Milltronicstransducers available by the programming of P-01. Refer to section Specifications\Transducers for detailedspecifications.

DAMPING AND PROCESS RATE

The AiRanger XPL provides damping to control the maximum rate of change of the displayed material level orvolume and of the mA output signal. As most relay functions respond to the dampened level reading, theyindirectly fall under the control of the damping function. Damping may be set within the range of 0.001 to 9999in percent of span per minute. Pressing will momentarily show the damping calculated in linear units per minute.

e.g. if P-02 (units) = 3 (ft) P-04 (span) = 10 and P-40 (fill damping) = 15 (%) of span/min then the maximum fill damping rate is 1.5 ft/min

P-40 is set to provide damping specifically for filling conditions while P-41 is set to provide damping specificallyfor emptying conditions.

The required damping may be estimated by filling and emptying the vessel at its normal rate. The rate ofmaterial level change can be viewed via process rate display parameter, P-42 or by pressing "7" while in theRun mode. The amount of P-40 and P-41 damping should be equal to or greater than the rates of levelchange encountered in P-42. The process rate averaging parameter P- 43 selects the method of averagingused to determine the process rate display, however it has no bearing on the damping function.

Damping is often used to slow down the rate of response of the display especially where liquid surfaces are inagitation or material falls into the sound path during filling.

When in the Calibrate mode, the damping is automatically overridden to give fast response when MEAS ispressed. In the Run mode, the response can be further increased by turning the fuzz filter (P-46) and the echodiscrimination (P-47) OFF - ONLY if they are not required.

If the transducer aiming is being adjusted while in the Run mode, it is suggested that damping be at its factorysetting of 100 to start. The damping can later be changed to suit prevailing conditions.

92/03/16PL-336 5 – 3

Upon a loss of echo condition and after the fail-safe timer (P-45) expires, the display will go to fail-safe high atthe fill damping rate if P-44 = 1 or to fail-safe low at the empty damping rate if P-44 = 2.

TEMPERATURE

In order to compensate for uniform temperature changes of the sound medium over time, temperature sensingshould be used. This will allow the AiRanger XPL to more accurately measure the physical distances whenthe transducer is subjected to temperatures other than 20 °C. The expected error due to temperature changeswill decrease from 0.17% per Celsius degree over the operating range to 0.09%.

The AiRanger XPL is supplied with or without an optional Temperature Input Board (TIB-10).

WITHOUT TIB-10

The AiRanger XPL comes factory set with a jumper across board B terminals TB1- 3/4 to simulate thetemperature programmed into P-35 (factory set for 20 °C, for all points). By removing the jumper and installinga temperature sensor, automatic temperature compensation common to all points is provided (refer to figures3 and 5).

WITH TIB-10

If a Temperature Input Board has been installed, the temperature input sensing terminals on the board B willbe ignored.

The TIB-10 allows the temperature at individual points to be sensed in order to provide automaticcompensation. The TIB-10 comes factory set with jumpers across its 10 point input terminal board, TB1, tosimulate the per point temperature programmed into P-35 (factory set for 20 °C).

A point requiring automatic temperature compensation must have its jumper removed and a temperaturesensor connected. Refer to section Installation\Temperature Sensing.

TEMPERATURE SENSING

A temperature sensor, when used, should be mounted in a location which represents the temperaturefluctuations likely to occur between the transducer and the target. Avoid mounting the temperature in directsunlight as radiant heating can cause a pronounced difference between the air and the transducertemperatures.

Any combination of the three temperature sensor models can be used with the AiRanger XPL. The followinghighlights the more important characteristics which have a bearing on their selection. Refer to sectionSpecifications\Temperature Sensors for detailed specifications.

LTS-1: stainless steel, FM and BASEEFA approval only

LTS-1C: stainless steel , CSA approval only

92/03/16PL-336 5 – 4

If the transducer’s ambient temperature is to remain constant, compensation may be programmed into theAiRanger XPL, instead of using a temperature sensor, by one of following methods.

1. - set jumper across temperature sensing input terminals corresponding to the applicable scan point- select P-35- enter temperature in °C

2. - select P-31- perform an empty calibration

The following temperature functions (in °C) can be viewed :

P-35 air temp. - present temperature at sensor or

- preset temperature, if sensor not used

P-36 max. air temp. - highest temperature encountered during operation

P-37 min. air temp. - lowest temperature encountered during operation

SOUND VELOCITY

The AiRanger XPL can be calibrated to compensate for transducer operation in homogenous vapours withsound velocities other than that of air.

The basis is to physically measure the level (measuring tape or sight glass) and enter this value via P-31. TheAiRanger XPL then calculates the sound velocity by comparing the entered physical measurement to its ownultrasonic measurement (empty calibration, P-31).

P-33, velocity at 20 °C, can be used to enter the known velocity of sound in a particular gas or vapour at 20 °Cor to view the resultant velocity of a sound velocity compensation, normalized to 20 °C.

P-34, velocity at P-35, can be used to enter the known velocity at the temperature of P-35 of sound in aparticular gas or vapour or to view the resultant velocity of a sound velocity compensation, at the temperatureof P- 35.

Refer to Appendix I, for typical sound velocities in various gases and vapours.

BLANKING

Near blanking (P-61) is used to ignore the zone in front of the transducer where ringing or other false echo isat a level that interferes with the processing of the true echo. The minimum near blanking is automaticallygiven a default value when the transducer code is entered (P-01). It can be overridden by entering the desiredamount into P-61. If the code in P-01 is re-entered or changed, the minimum near blanking value will be resetto the default value.

Ringing is the inherent nature of the transducer mass to continue vibrating after the transmit pulse has ceased.The amount of ringing varies with the type of transducer used and decays to acceptable levels in the order ofmilliseconds. Excessive cold and over tightening of the transducer mounting (refer to figure 3) will increase thering time such that it may appear as an echo during the receive cycle. This is usually indicated by an incorrecthigh level reading. This condition may be verified with the use of an oscilloscope (refer to sectionTroubleshooting\Oscilloscope) and may be overcome by increasing the near blanking.

92/03/16PL-336 5 – 5

Far end blanking is a design function that ignores the zone below the zero or empty level where false echoesmay appear at levels that interfere with the processing of the true echo.

In applications where the zero level is above the bottom of the vessel and it is desired to monitor the zonebelow the normal zero, range extension (P-62) may be used to extend the range into the far end blanking.Range extension is entered as a percent of P-03. As range extension reduces the protection afforded by thefar end blanking, it should be used judiciously. Avoid excessive range extension as this may reduce themeasurement’s reliability and accuracy. Range extension is factory set for 20% of P-03. If it is found that falseechoes are appearing ahead of the blanking zone, P-62 should be reduced accordingly.

Blanking is automatically corrected for sound velocity change where temperature and velocity compensationare used; keeping the blanking at the distance at which it was entered.

ECHO DISCRIMINATION

In applications where false echoes are appearing due to agitator blades or transient noise, echo discrimination(P-47) may be used in order to lock onto the true echo. When echo discrimination is turned on, the windowcreated during the processing of the echo is placed around the true echo. The window will not move untilcertain criteria are met. The width of the window (P-48) can be changed to suit the application.

In applications where there is an agitator operating in the vessel, the blades may interfere with level readingswhen the material level is lower than the blades. In such a case, agitator discrimination (P-47=1) can beturned on (factory setting). With the agitator discrimination turned on, the reading will not change unless theecho is ahead of the window (closer) for 5 consecutive measurements or is behind the window (farther) for 2consecutive measurements.

In applications where there is transient noise, acoustical or electrical, signals generated in the transducercircuit or in the transceiver may appear as echoes. In such a case, transient discrimination (P-47=2) can beturned on. With the transient discrimination turned on, the reading will not change unless the echo is outsidethe window (closer or farther) for 5 consecutive measurements.

Echo discrimination, however, slows down the AiRanger XPL’s speed of response. Therefore, if fast responseis required, especially when aiming the transducer while in the run mode, and if there is no agitator or transientechoes involved, the discrimination should be turned off.

Agitator discrimination will not work if the blades are stationary and in the transducer’s beam path.

LOSS OF ECHO

A loss of echo occurs when neither the short or long measurement (P-71) confidence is above the respective

threshold (P-72).

If the loss of echo is due to an open or short in the transducer circuit, the display will immediately flash

The following conditions will apply when the default reading has reached its limit. The relay status applies if

the high and low alarms have not been set beyond 100% and 0% respectively.

FAIL-SAFE MODE RELAY STATUS ANALOG OUTPUT P-44 high alarm low alarm P-06=1 or 2 P-06=3 or 4

Upon receiving an echo above the threshold and satisfying the echo discrimination (P-47) criteria the loss ofecho condition will be aborted and the reading will move to the present level at the appropriate damping rate.

RELAYS

GENERAL

All alarm relays associated with the AiRanger XPL are located in the optional Satellite Alarm Module, SAM-20,peripheral. The AiRanger XPL itself has no on board alarm relays. The AiRanger XPL serves as the host forprogramming and alarm status display and transmission to the SAM-20.

Each point may be assigned one or more relays and each relay may be assigned one out of six functions.

FUNCTIONS

level : high alarm: alarm ON status occurs when the level rises to the ON setpoint and returns to normal when the level lowers to the OFF setpoint.

low alarm: alarm ON status occurs when the level lowers to the ON setpoint and returns to normal when the level rises to the OFF setpoint.

/ and a default measurement (P-44) in alternating fashion. The default measurement

will be immediately forced to the 0% (fail-safe low) or 100% (fail-safe high) of span level or hold the last

measurement prior to the loss of echo condition.

If the loss fo echo is due to some other reason, the display will hold the last measurement. If the condition

persists for a time beyond the limit as set by the fail-safe timer (P-45), then the display will begin to alternately

flash and a default measurement. The default measurement will be forced to the 0% (fail-safe low)

or 100% (fail-safe high) of span value at the respective fill (P-40) or empty (P-41) damping rate or hold the last

measurement prior to the loss of echo condition.

Pressing will bypass these delays and yield an accurate response immediately. As the defaultmeasurement changes, alarm status and analog output will respond.

92/03/16PL-336 5 – 7

Pressing while programming the alarm function P-13 will cause the left side characters of the Reading field to scroll through the alarm ON status codes :

L - low alarmLL - low low alarmH - high alarmHH - high high alarm

in bounds: alarm ON status occurs when the level is inside the zone between the setpoints and returns to normal when the level goes outside the defined zone.

out of bounds: alarm ON status occurs when the level is outside of the zone between the setpoints and returns to normal when the level goes inside the defined zone.

Pressing while programming the alarm function P-13 will cause the left side characters of the Reading field to scroll through the alarm ON status codes :

b1 - band alarm #1b2 - band alarm #2

rate of change : high alarm: alarm ON status occurs when the process rate (P-42) increases to the ON setpoint and returns to normal when the rate decreases to the OFF setpoint.

low alarm: alarm ON status occurs when the process rate (P-42) decreases to the ON setpoint and returns to normal when the rate increases to the OFF setpoint.

Pressing while programming the alarm function P-13 will cause the left sidecharacter of the Reading field to scroll through the alarm ON status codes:

r1 - rate alarm #1r2 - rate alarm #2

temperature : high alarm: alarm ON status occurs when the sensed temperature (P-35) increases to the ON setpoint and returns to normal when the temperature decreases to theOFF setpoint.

low alarm: alarm ON status occurs when the sensed temperature (P-35) decreases to the ON setpoint and returns to normal when the temperature increases to the OFF setpoint.

loss of echo : alarm ON status occurs under a loss of echo condition.

SETPOINTS

high alarm: the ON setpoint is above the OFF setpoint

low alarm: the OFF setpoint is above the ON setpoint

The ON and OFF setpoints can not be the same on an individual relay but may be common to other relays.The deadband or hysteresis is difference between the ON and OFF setpoints for custom level alarms. Forstandard level alarms, the hysteresis is set at 5% of span from the ON setpoint. For in and out of bounds levelalarms, the hysteresis is set ±2% of span from either boundary.

93/07/07PL-336 5 – 8

The level alarm setpoints are measured from the bottom up, referenced to zero and are programmed as apercent of span, P-04. The rate alarm setpoints are programmed as a percent of span per minute. By pressing while viewing a setpoint parameter, the setpoint in linear units will be momentarily displayed. Refer toexample in Standard or Custom Programming. The temperature alarm setpoints are programmed in degreesCelsius. The loss of echo alarm does not have a setpoint dedicated to its own use, but is controlled by the fail-safe timer, P-45.

RELAY STATUS

During alarm OFF status, the corresponding SAM-20 relays are energized. A relay under alarm ON status willbe de-energized. At this time a status code, if programmed, will be displayed in the ‘Status’ field of the lefthand display and transmitted via the ±20 mA bipolar current loop. Only the alarm ON status code for high, highhigh, low and low low level alarms can be displayed. Alarm ON status data for level and and rate of changealarms is transmitted for customer use via the BIC .

While in the Calibrate mode, alarm relays will hold their prior status, but will respond to measurements taken when is pressed. The alarm ON status however will not be displayed in the status field.

Refer to "Loss of Echo" for relay status during a loss of echo condition.

PROGRAMMING

Alarm programming may be done by one of two methods.

The standard method would be used on tank farms for instance, where the tanks are similar and the alarmsare limited to high and low level programming.

The custom method would be used where the user feels limited by the alarm programming available to himthrough the standard method.

It must be noted that the two methods are interactive; programming a common set of alarms. The lattermethod used to program the relays overrides the settings programmed by the previous method.

The AiRanger XPL may be programmed to control up to 40 relays. The relay set is divided into two banks of20 relays each. The banks are identified as 1 and 2, corresponding to the bank setting on SAM-20 peripherals.The relays are identified as 1 to 20, corresponding to the relay numbers on the SAM-20 peripherals.

STANDARD

Standard programming accesses the relays by point number. Alarm ON setpoints are programmed viaparameters 07, 08, 09 and 10 for high, low, high high and low low alarms respectively.

The ON setpoints may be altered or viewed globally, point 00 or on a per point basis.

The factory setting for the access parameters assigns: - a high alarm at 80% via P-7 to all points, activated- a low alarm at 20% via P-8 to all points, activated- a high high alarm at 90% via P-9 to all points, OFF- a low low alarm at 10% via P-10 to all points, OFF

Standard programming involves the following two steps:

- select parameter 07, 08, 09, or 10 e.g.

- per point : - select point e.g.

If a relay funtion has been changed via the custom parameter P-13, then CH (changed) or OFF will bedisplayed instead of the setpoints when viewing parameters P-07, P-08, P-09 and P-10.

2. relay assignment

Refer to section, Parameter Description\Relay Parameters\P-11

CUSTOM

Custom programming accesses the relay bank and relay number. Access is gained through parameters (12,13, 14 and 15). It may be done subsequent to the programming of the standard alarm parameters, therebycustomizing these settings or done directly, by-passing the standard parameters. In either case, the customprogramming will override the settings of the standard programming. Thus if it desired to make use of thestandard programming, it should be done prior to the custom programming.

SIMULATION

Parameters P-50 through P-53 can be used to simulate alarm conditions while in the Calibrate mode. Whenan alarm condition occurs, the alarm status will be displayed, if programmed, and the corresponding SAM-20relay and status LED will respond. Refer to section Parameter Description\Simulation and Measurement.

If the relay status can affect plant operation or personnel safety, it is advisable to override the relay functions by disconnecting the relay wiring or locking out the power to the associated piece of equipment.

ANALOG OUTPUT

GENERAL

All analog output associated with the AiRanger XPL is located in the optional Analog Output, AO-10,peripheral. The AiRanger XPL itself has no on board analog output. The AiRanger XPL serves as the host forprogramming and analog output display.

Each output may be assigned to any one point or to represent a multipoint average. When assigned to onepoint, the output retains its last updated value to provide a continuous output while other points are beingscanned. When multipoint averaging is selected, the analog output is the average value of the analog outputsof the in service points (P-1) assigned.

The AiRanger XPL can be programmed to provide an analog output (P-06) range of 0 or 4 - 20 mA, and forproportional or inverse span.

The analog output responds in the following manner:

The analog output feature may be turned OFF at the AiRanger XPL by setting P-6 = 0. The AO-10 outputsand alternate displays ( & P-97 ) will immediately drop to 0 mA after a new measurement is processed.The output will remain disabled during simulation ( P-50 to 53 ). However the test routine of P-97 and the trimparameters will remain active. If P-6 ≠ 0, then the analog output will return to its programmed output after anew measurement is processed.

RUN/CAL

When the mode of operation is changed from Calibrate to Run, the transceiver resumes its operation. Thereading displayed will be the default reading (P-50) of the measurement taken, either prior to entering or whilein the calibrate mode. The reading will move at a rate controlled principally by the damping (P-40 or P-41) andecho discrimination (P-47). On a multipoint system, it may take a considerable time for the reading to reach thecurrent measurement. Pressing until is shown in the Reading field will force the reading,for thepoint displayed only, to the current measurement immediately. If there are no points in service, the display willshow .

When the mode of operation is changed from Run to Calibrate, the transceiver stops operating. The lastmeasurement is stored and the readings, alarm status and analog output levels are frozen. If is pressed,the AiRanger XPL will react as if it were momentarily placed in the Run mode. Otherwise, it can not respond tochanges in level while in the Calibrate mode.

SECTION VI

APPLICATIONS

This section highlights the most common applications to which the AiRanger XPL can be applied. Otherapplications not listed here may be akin to those listed or a combination thereof (e.g. monitoring piston positionon a wood pulverizer is in essence a level application).

When calibrating, refer to the application which is most similar to yours. A practical example has been given tofurther illustrate the calibrating features used for an application. In actual practice, however, the example maynot cover all facets of the particular application. Therefore, the user should become familiar with the host ofparameters available. Refer to section Parameter Description

The minimum distance from the transducer face to the target is dependent upon the type oftransducer being used. Minimum blanking should be limited as follows:

ST-25 30 cm (1 ft)ST-50 30 cm (1 ft)ST-100 90 cm (3 ft)LR-21 90 cm (3 ft)LR-13 120 cm (4 ft)

PL-336 6 – 1

SIMPLE LEVEL APPLICATION

The most common application of the Milltronics ultrasonic level measuring systems is for simple levelmonitoring, whereby the material level or space between the transducer and reflecting surface is measuredand displayed. This may or may not include alarms and analog output.

EXAMPLE 1

The application is to obtain level measurements in a 30 ft high vessel and a corresponding 4 - 20 mA output.An LR-21 transducer is installed, its face made level to the top of the vessel designated as point 1. The emptylevel will be at 0 ft (bottom) and the full level will be at 27 ft from the bottom (span). A high alarm is required at4 ft from the top (26 ft from the bottom) and a low alarm is required at 5 ft from the bottom. The maximumfill/empty rate is 1 ft/min. In the event of a loss of echo, the AiRanger XPL is to go into fail-safe hold after 2minutes.

VOLUME APPLICATION In addition to simple level applications, volume conversions can be included in the calibration. Volumeconversion should be done on liquid materials only.

Volume conversion is provided for 8 common tank shapes, (P-21). Dimensions are entered using P-04, P-22and P-23. Volume is displayed as 0 - 100% (P-21≠0) and may be converted to volume units by entering aconversion factor into P-24.

Note that P-04, span, must equal 100% (full) level of tank. In many volume applications, the ambient atmosphere is other than air or at a temperature other than 20 °C.Refer to section Functional\Temperature and \Sound Velocity for details on compensating for suchcircumstances.

If it is noted that the AiRanger XPL reading is consistently off by a constant amount as compared to thephysical measurement, this may be compensated for by the measurement offset parameter (P-32).Measurement offset might occur when P-03 or P-04 do not exactly match the tank dimensions referenced forvolume conversion. If the cause of the offset appears below the relay setpoints, the setpoint parameters mayneed to be reset as these will have shifted accordingly.

Refer to figure 11.

EXAMPLE 2

The application is to measure the volume of glue in a horizontal tank with parabolic ends. The tank has beendesignated as point 1 and has been fitted with an ST-25 flanged transducer. The tank manufacturer‘sspecifications state that the total volume is 50 cubic meters.

The maximum fill/draw rate is 0.35 m3/min. In the event of a loss of echo, the AiRanger XPL is to go intofail-safe high after 30 sec.

NOTE : As the glue gives off formaldehyde vapour, a velocity compensation will be required.

APPLICATIONS WITH STANDPIPE

In many solids and liquid applications, access to the vessel must be made via a standpipe. In such cases,Milltronics can provide flange mounted ST-series transducers that will readily mate to the flanged standpipe(refer to figure 11). Another option is to hang the transducer from a blind flange.

The standpipe length should be as short and the diameter as large as possible. As a rule of thumb, the -3 dBcone of the sound beam should not intersect the standpipe wall in applications opening into a vessel.Otherwise, additional near blanking (P-61) will be required to compensate for the interference zone created bythe opening. The rise to run ratio (beam angle)* of the cone can be estimated as follows:

P-56 associative scanning (S.R. 2.0)

by entering another point number into this parameter, the point being programmed and the point being indexed by P-56 will work in association. By assigning different transducer modelsto work in association, the advantages of each transducer can be capitalized.

When a point set for associative scanning is being scanned, the AiRanger XPL uses the measurement of the indexed point, if it is valid, rather than take its own ultrasonic measurement.

If the indexed point does not hold a valid measurement, the point being scanned will take its ownultrasonic measurement. The indexed point will take its turn in the proper scanning sequence.

e.g. if the 1.2 m of blanking required by using an LR-13 transducer is unacceptable, an ST-25 transducer having 0.3 m of blanking can be installed in the same silo. If point 1 is set to scan with the LR-13 and point 2 is set to scan with the ST-25, then by setting point 1, P-56to ‘2’, the LR-13 will not fire until the material drops out of range of the ST-25 and no validmeasurement is obtained. When this condition occurs, the LR-13 will fire first and then theST-25 will fire. When a valid measurement is obtained on point 2, point 1 will not fire.

minimum echo confidence in dB for which at least either the short or long echo must meet in order to prevent a loss of echo condition and the expiration of the fail-timer (P-45). (F=10: 5)

short pulse echolong pulse echo

Typical usage:

- short echo: if transducer were picking up small unwanted short pulse echoes, increase threshold to a value above that of the short pulse echo confidence (P-71) so that close in echoes are no longer valid.

- long echo: during filling of vessel, material intersects beam path. Instead of displaying wrong level, increasing threshold to a value above that of the echo confidence (P-71) will force the AiRanger XPL into fail-safe.

P-73 window sill

sets the level at which the bottom of window (sill), used in echo discrimination, crosses the echo.Range 5 to 95% of echo rising edge.

ADVANCED CALIBRATION

Advanced calibration should only be attempted after all the basic checks such as wiring, transduceraiming, parameter entry, simulation and troubleshooting tips have been double checked and thedesired results are not yet obtained.

The use of an oscilloscope (P-60) is required to effectively use most of the echo processingparameters (P-60 through P-89).

When performing an advanced calibration, work with one parameter at a time. if no improvement isobtained, clear that parameter to reset it to its default value and try another applicable parameter.

Avoid altering more than one parameter at a time without noting its effect.

SYMPTOM CAUSE ACTION

PL-336 8 – 3

OSCILLOSCOPE

An oscilloscope can be used to view the transmit, receive and processed echo signals. Connect as follows:

oscilloscope location description

probe - J2, RCVR, board A - amplified receiver signal - J4, SCOPE, board A - processed echo - TB1-11, 13, 15...29, - raw transmit/receive signal

board B points 1 through 10 external trigger - J3, SYNC, board A - oscilloscope synchronization ground - J5, COM, board A - ground

The transmit and receive signals are best viewed while in the Run mode or with P-95, transmitter test, set tofire automatically in the calibrate mode. This may be useful when aiming the transducer to obtain the bestecho.

To view the processed echo, P-60 must be set for the desired display. If the Calibrate mode is exited for morethan 10 minutes, P-60 will have to be reset to view the displays on the oscilloscope.

The processed echo can be viewed and updated by pressing . This must be done while in the Calibrate

stored echo will be reprocessed. The results can be monitored on both the AiRanger XPL display and on theoscilloscope.

Typical scope settings for viewing the processed echo are: - gain: 1 v/div - sweep: 1 mSec/div

The processed echo display can be programmed to show any combination of four of the following displays: - echo profile- echo marker- window - TVT curve - pointer

The pointer can be used in analysing the echo profile. For example if a false echo is appearing in the profile,it can be moved to point at the echo and its distance from the transducer displayed. This can be useful inidentifying th source of the echo. Refer to section Parameter Description\Echo Selection and Analysis\P-77,P-78 and P-79.

Maintenance and Spare Parts

MAINTENANCE

The AiRanger XPL requires no maintenance. However, a program of periodic preventive maintenance shouldbe initiated. This should include regular inspection, general cleaning and good housekeeping practices.

Enclosures and circuit boards should be cleaned only when the power is disconnected at the main breaker.Using a vacuum and clean, dry paint brush, check all electrical terminals for corrosion and arcing.

If the AiRanger XPL is mounted in a dusty or oily environment, make sure that the calibrator and front coverare kept clean, otherwise it may impede the infrared signal transmission required for programming.

It is also a good idea to periodically check the face of the transducer. It should be free of material build-upcorrosion or deformation.

COMMUNICATION

The AiRanger XPL is capable of transmitting data at 4800 baud, over a ± 20 mA current loop. The maximumdata loop length is 3000 m (10,000).

For data transmission to take place, the AiRanger XPL ASCII transmitter must be on ( P - 54 = 1, factorysetting ) .

Utilizing Simplex convention, data is transmitted on a regular basis ( approximaitely every 3 seconds ).

This output ( board B, TB1 - 6 and 7 ), may be connected directly to AiRanger XPL peripherals also designedfor serial communication.

For connection to a host computer or programmable logic controller, a BIC-II buffered interface converter mustbe used to convert the data to the RS-232C or RS-422 format required by the host device.

Refer to the appropriate instruction manual for serial communication interconnection diagrams.

DEVICE INSTRUCTION MANUALAO-10 PL-337SAM-20 PL-338BIC-II PL-371

COMMUNICATION PROTOCOL

Communication Protocol refers to the format, sequence and value of the data fields utilized in serialcommunication messages.

The AiRanger XPL transmits specific messages consisting of a number of data fields, containing byte(s) inASCII binary code format :

› 7 data bits› even parity› one stop bit

Each byte represents an ASCII hexadecimal value which is equivalent to an ASCII character.

The ASCII character will be equal to the true hexadecimal value the AiRanger XPL derived from a true binaryprocessing result.

e.g. if the XPL true binary processing result = 0100the true hexadecimal value = 4then the ASCII binary byte transmitted = 011 0100whose ASCII hexadecimal value = 34whose ASCII character equivalent = 4

In solids applications, the transducer should be mounted so that it is aimed toward the low level draw point.To facilitate this mounting, it is suggested that the optional Milltronics Easy Aimer Kit be used.

PL-336 10 -10

EASY AIMER KIT INSTALLATION

1. Assemble transducer to conduit via reducing coupling supplied and feedconduit through center hole of aiming fitting, secure assembly with the conduit clamping screws.

2. Install locknut onto top end of threaded conduit

3. Bolt down mounting block ( i.e. to access plate of bin ) in a location away fromfill points or structural members that may intersect the sound’s path toward the low level draw point.

4. Leaving the sighting block binding screws fastened, loosen the angle blockbinding screws. Rotate angle block until transducer is pointing at the desiredangle. Angle reference graduations on the sighting block are 3.3° apart; e.g. ifline at 0° on angle block is 2 graduations past the 0° on the sightingblock, then transducer is angled at 6.6° from vertical.

Re-fasten angle block binding screws.

5. Lossen the sighting block binding screws and rotate sighting block untiltransducer is pointing in the desired direction. Direction reference graduationson the mounting block are 30° apart.

Re-fasten sighting block binding screws.

NOTE : It may take several attemps at various angles/directions to obtainoptimum results. Refer to sections Installation\Transducers andTroubleshooting\General for guidelines in aiming the transducer.
