3 Introduction

3.1 Overview

The LLT100 is a laser-based distance measuring transmitter used in process control systems. The on-board microprocessor calculates distance by multiplying the speed of light by the time taken by a laser pulse to travel from the transmitter to a target and back.

The measuring laser uses invisible, infrared light. The laser beam has very little divergence so that accurate targeting is easy even in silos or vessels that have internal structures.

3.2 LLT100 key features – Narrow beam for direct targeting – Non-contact measurement – Maintenance-free – Measurement in dusty/foggy environment – Measurement in hygienic environment – Long distance measuring capability – Gas flameproof and dust exclusion proof – Measurements of solids are not affected by the angle or roughness of the surface being measured – Immunity to nearby objects, to vessel shape and to the material of construction of the vessel

– Ability to reject momentary obstacles


Solid application

A typical application with the LLT100 is to measure the level of solid material in silos or tanks in industries such as: food and beverage, mining, aggregates, chemicals, oil & gas, and food and beverage.

Many problems occur in this field of level measurement, which can be solved by using the LLT100. For example dusty environment, viscous or half solid half liquid material, hygienic standards, material properties (low dielectrical), specific installation angles, damage and or maintenance for contact devices, accumulation on silo sides, narrow silo shapes

Liquid application

One of the most desired featured of LM80 was the level measurement of clear liquids. This is now possible with the LLT100 and make this device also independent of liquid material properties and conditions. Especially the industries of chemical, water and waste water, oil & gas, food & beverage, pharmaceutical and many more, can now be handled with a wider range of application solutions

Furthermore, the LLT100 comes with high pressure flanges.

Mixer/Obstruction

Another challenge in the field of level measurement is the reliable measurement in the presence of obstructions or mixing blades.

The narrow beam of the LLT100 allows to install the device at almost any place at the top of a tank or silo. Thus the LLT100 can easily prevent mixer/obstruction problems. For example, even if it is not possible to avoid mixer blades, the LLT100 icludes a function to remove the presence of blades and delivers a reliable level measurement, refer to section 6.10 Measurement modes and filter options on page 46 (No measurement period function).

Positioning

A different field to use for the LLT100 is the distance measuring of wagons, trippercars or similar to position them accurately so they can load or unload in the right place. Additionally, the monitoring of the position can prevent or avoid collisions.

4 Installation considerations

4.1 General information

The LLT100 is an optical, line of sight device that is used for non-contact distance measurement. There must be no obstacles directly in the beam path.

The LLT100 measures in engineering units (feet or meters) and there is no need for calibration prior to installation. The transmitter can simply be aimed directly towards an object and it will measure the real physical distance from its surface. Any special settings required by the user may be loaded into the device inside the work area or workshop prior to mounting the LLT100 outside.

Study these installation instructions carefully before proceeding. Failure to observe the warnings and instructions may cause a malfunction or personal hazard. Before installing the LLT100, check whether the device design meets the requirements of the measuring point from a measurement technology and safety point of view.

This applies with respect to:

– Explosion protection certification – Measuring range – Temperature – Operating voltage

The suitability of the materials must be checked with regards to their resistance to the media. This applies with respect to:

– Gasket – Process connection, isolating diaphragm, mounting screws

etc.

In addition, the relevant directives, regulations, standards, and accident prevention regulations and national standards must be observed. Measurement accuracy is largely dependent on correct installation of the LLT100. As far as possible, the

measuring setup should be free from critical ambient conditions such as large variations in temperature, vibrations, or shocks.

Attention – Property damage

If unfavorable ambient conditions cannot be avoided for reasons relating to building structure, measurement technology, or other issues, the measurement quality may be affected.

4.2 IP protection and designation

The housings for LLT100 are certified as conforming to protection type IP66/IP67 (according to IEC 60529) or Type 4X (according to NEMA 250).

The first number indicates the type of protection the integrated electronics have against the entry of foreign bodies, including dust: number 6 means that the housing is dust-proof (i.e., no ingress of dust).

The second number indicates the type of protection the integrated electronics have against the entry of water:

• Number 6 means that the housing is protected against water; specifically, against the effects of powerful jets.

• Number 7 means that the housing is protected against water; specifically, against the effects of temporary immersion in water under standardized water pressure and temporal conditions.

4.3 Environmental

The LLT100 should be installed in an area that is within the specified temperature range (see Appendix A – Technical Specifications on page 73), taking into consideration the enclosure ratings and the materials of construction.

Figure 13: Operating Temperature Limits

60 °C / 140 °F - 40 °C / - 40 °F



4.4 Mounting considerations

Make sure to observe the suggested mounting arrangements and also the shown mounting arrangements that should be avoided. Refer to Figure 27 on page 32 and to Figure 29 on page 33.

4.4.1 LLT100 factory configuration consideration

The LLT100 in your hands has been factory calibrated to reflect the published declared performance specification; no further calibration is required in normal usage condition.

4.4.2 Hazardous area considerations

The LLT100 must only be installed in hazardous areas for which it is properly certified. The certification plate is permanently fixed on the neck of the LLT100 top housing. For specific hazardous area installation considerations, see chapter 9 Hazardous Area considerations on page 69.

Attention – Property damageGeneral risk for aluminum models used in zone 0. The enclosure contains aluminum and is considered to present a potential risk of ignition by impact or friction. Care must be taken into account during installation and use to prevent impact or friction.

4.4.3 Integral display rotation

When an optional integral display is installed, it is possible to mount the display in four different positions rotated clockwise or counterclockwise with 90° steps.

To rotate the LCD

1. Open the windowed cover (Hazardous area prescriptions must be respected).

2. Pull-out the display housing from the communication board.

3. Reposition the LCD connector according to the new desired position.

4. Push back the LCD module on the communication board.

Be sure that the four plastic fixing locks are properly in place.

For Ex d installations, please refer to note Important – Securing the housing cover in flameproof areas on page 44.


4.4.4 LLT100 housing rotation

To improve field access to the wiring or the visibility of the optional LCD, the LLT100 housing may be rotated from initial position -45° and + 90° and fixed in either of these position. A stop prevents the housing from being turned too far. In order to proceed with housing rotation, the housing stop tang-screw has to be unscrewed by approximately 1 rotation (do not pull it out) and, once the desired position has been reached, retightened.

WARNING – Property DamageThe LLT100 housing can only be rotated from its initial position -45° and + 90° and fixed in either of these position. Turning beyond these limits may permanently damage the LLT100 transmitter.

Figure 14: Housing rotation

+90° -45°



4.5 Unpacking

The product is supplied in a cardboard container with internal shock absorbing packaging. Check the entire box content for accessories that may be wrapped and may appear hidden. ABB recommends to keep the original packaging material to always transport the transmitter in the supplied packaging to reduce the chance of damage. If the original packing material is not kept and the LLT100 has to be returned to the manufacturer for repair, make sure to sufficiently protect the transmitter for transportation.

4.6 Handling

The product is designed to withstand many industrial environmental conditions. However, a few handling precautions will ensure reliable operation of the unit for extended periods of time.

– DO NOT DROP THE TRANSMITTER. – Remove dirt from the window with compressed air or if not

sufficient, clean with alcohol and optical wipes. – Do not install or connect with the power on. – Do not open the transmitter compartment or expose the

internal electronics to water or dirt. – Ensure that the cable glands or conduits are tight after

connecting the external cable. – Ensure that the lid to the terminal compartment is tight after

connections have been made. – Do not point the transmitter at the sun. – Do not open or modify the transmitter. – Store in a cool dry place. – Respect electrical specifications.

4.7 Installation steps and details

The LLT100 is delivered as an assembly. The one or more gaskets, bolts, washers and nuts are not included and have to be selected according to the process and/or national standard. Make sure to locate all bolts, nuts and washer and respect the appropriate order as detailed in Figure 15: Standard flat face flange LLT100 installation, ASME/DIN Universal on page 23.

Select the appropriate gasket for the application, i.e. a gasket that complies with the ASME B16.5 standard or the standard required by the user. The gasket and transmitter flange are to be selected according to the service condition of the application.

For all types of flanges:

Tighten the flange bolts in an alternating crisscross pattern to a torque value of one-fourth of the final bolting torque. Repeat this procedure several times, increasing the torque value each time by a fourth of the final torque value. After applying the final torque value, tighten each bolt again to allow for gasket compression.

4.7.4 Dusty conditions

In dusty conditions, it is strongly recommended that a Dust Tube be installed (see Appendix B – Accessories on page 75). In extremely dusty conditions, for example during a filling process if the signal is lost for too long, the measurement may be temporarily unavailable. Refer also to sections 6.10 Measurement modes and filter options on page 46 and 6.11.1 Easy Setup on page 49.

The dust tube is a very simple and effective device, designed to prevent dust settling on the lens. The LLT100 can be used in most dust present applications by using the dust tube accessory.

4.7.5 Foggy conditions

In foggy conditions, it is strongly recommended that the heated window option be used (see Appendix B – Accessories on page 75). In extremely foggy conditions, for example during a filling process if the signal is lost for too long, the measurement may be temporarily unavailable. Refer also to sections 6.10 Measurement modes and filter options on page 46 and 6.11.1 Easy Setup on page 49.

4.8 Alignment

The LLT100 is simple to install and align. It has a narrow and direct beam so there is no interference from nearby objects. The output beam is factory aligned perpendicular to the transmitter’s front window (90 ± 0.5).

The main consideration required when aligning the transmitter is a clear line of sight.

The LLT100 will measure off a surface that is rough or is at an oblique angle to the beam. There is no need to align the transmitter perpendicular to the material as it will not be affected by the cone up or down of the material. However, for liquid applications, mount the laser perpendicular as far as possible to the surface. A misalignment up to 5 degrees may be acceptable in very good conditions (short distance, smooth surface, clear light). For long distances a deviation of 1–2 degrees might be necessary for optimal performances.

The laser beam forms a rectangular shape. For example, at a 30 m distance, the beam is 20 cm by 3 cm. The long side of the rectangle is in line with the blocking screw, as indicated in Figure 18: Laser beam details on page 26. This screw is factory-secured and cannot be untightened. If there is an obstacle in the trajectory of the laser beam, make sure to align the obstacle parallel to the laser beam's long side by using the flange to rotate the whole instrument.

Blocking screw


4.9 Mounting

The LLT100 produces a narrow, straight and invisible laser beam. It should be mounted facing directly towards the area to be measured with no obstacles directly in the beam path.

Mounting depends on the flange and process type varying from 8 mounting holes, 4 mounting holes or a clamp in the case of the tri-clover version. The transmitter can be bolted directly onto a flange or bracket. For the pressure-rated applications make sure to respect the national codes and/or certification regulations in terms of mounting, bolts and gaskets.

In applications where dust may be present (even in very small quantities) it is recommended that a dust tube accessory be used.

Helpful tip

The LLT100 may receive stronger signals in subdued lighting and dark conditions than it does in direct sunlight.


Exposure to some chemicals may degrade the window or the sealing properties of the LLT100 or degrade the lens.


Explosion hazard. Do not open or disconnect equipment when a flammable or combustible atmosphere is present.


Always use thread sealant or conduit seal in order to maintain enclosure Type 4X and IP66/IP67 rating.


Avoid mounting the transmitter close to a stream of material that may fall in front of it. Avoid aiming the transmitter down long narrow pipes that have rough inner walls. Ensure that the transmitter never points directly at or near the sun. Check the operation over the full range of conditions to be measured after installing.

4.10 Alignment with the external commissioning laser device (if purchased)

If too many obstacles are present around the beam path, the external commissioning laser device can help to align the LLT100. Install the external commissioning laser device on the process flange or bracket and screw in place. Make sure two AAA type batteries are in the device. Turn on the external commissioning laser device and verify the alignment.

5 LLT100 wiring

WARNING – General risks

Observe the applicable regulations governing electrical installation. Connections must only be established in an unpowered state. Secure the breaker while working on the circuit to avoid accidental power-up. For continuous installation protection, a double insulation power supply (5kV or higher) shall be used for the current loop. The power supply shall be equipped with a short circuit protection function and along with an auto restart. For external installations exposed to lightning, a transient voltage suppression module or a galvanic isolator shall be installed with adequate grounding before entering a building with a cable to avoid personnel injury or property damage. Refer to local building code and electrical code for proper practices. The same power supply can be used for both the 4-20mA loop and the window heater. A second pair of wire shall be used to avoid excessive voltage drop exceeding LLT100 electrical specifications.

Electrical shock can result in death or serious injury. Avoid contact with the leads and terminals.

Do NOT make electrical connections unless the electrical code designation stamped on the LLT100 data plate agrees with the classification of the area in which the LLT100 is to be installed. Failure to comply with this warning can result in fire or explosion.

For 2-wire wiring, refer to Figure 33: LLT100 Terminal compartment, no heater – 2 wires on page 38 and Figure 36: Typical connection for 2 wires on page 39.

For 4-wire (with heater option) refer to Figure 32: LLT100 Terminal compartment, with heater option – 2 + 2 wires on page 38 and Figure 35: Typical connection for 2 + 2 wires

(alternate wiring) on page 39.

5.1 Cable connection

The LLT100 has a ½ inch NPT/M20 cable gland entry. A suitably certified ½ inch NPT/M20 cable gland being certified to either Ex db or Ex tb according to the installation, and having an IP rating of at least IP66/IP67 shall be used. The cable glands supplied by ABB are ATEX and CE certified and meet the above requirements.

These cable glands can only be used with braided shield cables. When installing them, make sure to fold the cable shield over the O-ring which presses the braiding against the inside wall of the body, this ensures good contact.

Important

For cable glands that are not supplied by ABB, please refer to your supplier’s data sheet for proper installation.

Important

Wires and cables glands shall be rated at least 90°C.


ABB does not assume any responsibility for non ATEX or CE certified cable glands or adaptor that do not meet the above requirements.

Important

It is the costumer's responsibility to use appropriate cable gland, screw plug, lube and/or sealant for the cable entry ports.

The installer assumes responsibility for any other type of sealing medium used. At this point, we wish to draw your attention to the fact that increased force will be required to unscrew the housing cover after an interval of several weeks.

This is not caused by the threads, but instead is due solely to the type of gasket.

DANGER – Serious damage to health/risk to lifeDuring installation, current to the 4-20 mA circuit should be interrupted for 60 seconds as otherwise it may cause a permanent error.

7 DCS/PLC

HART hand-held communicator may be connected at any wiring termination point in the loop, providing the minimum resistance is 250 ohm. If this is less than 250 ohm, additional resistance should be added to allow communications. The handheld terminal is connected between the resistor and the LLT100, not between the resistor and power source.

5.3 Supply requirement

For signal/power connection use twisted, stranded pairs of wiring no 18 to 22 AWG / 0.8 to 0.35 mm2 ø up to 5,000 feet (1500 meters). Longer loops require larger wire.

If a shielded wire is used, the shield should be grounded only at one end, not both ends. When wiring at LLT100 end, use the terminal located inside the housing marked with the appropriate sign.

The 4 to 20 mA DC output signal and the DC power supply to the LLT100 are carried from the same pairs of wires.

The supply voltage at the LLT100 terminals must be between the limits of 15.5 and 42V DC. If using 250 W for HART, limits are 21 V to 42 V if there is no load on the line.

For maximum power supply voltage please refer to the top identification plate of the LLT100.

The maximum current loop length usable with HART communication can be calculated using the following formula:

65 x 106 R x C

L =Cf + 10000 C

–

Where:

L = Line length in meters

R = Total resistance in Ω (ohms)

C = Line capacitance in pF/m

Cf = Maximum internal capacitance of the HART field devices located in the circuit, in pF

Avoid routing cables with other electrical cables (with inductive load, motors, etc.) or near large electrical equipment.



5.4 Wiring procedure

DANGER – Sharp surfaceDo not grab the transmitter by the threaded interface. The threaded edges are sharp and there is a risk of personal injury.

To wire the LLT100

1. Remove the temporary plastic cap from one of the two electrical connection ports located at both sides in the upper part of the LLT100 housing.These connection ports may have a 1/2 inch internal NPT or M20 threads. Various adaptors and bushings can be fitted to these threads to comply with plant wiring (conduit) standards.

2. Remove the housing cover on the “field terminals” side. See the indication on the label on top of the housing. In an explosion proof/flameproof installation, do not remove the LLT100 covers when power is applied to the unit.

3. Run the cable through the cable gland and the open port.4. Connect the positive lead to the + terminal, and the negative

lead to the – terminal in the case of HART.5. Plug and seal the electrical ports. Make sure that when

the installation has been completed, the electrical ports are properly sealed against entry of rain and/or corrosive vapors and gases.


Cable, cable gland and unused port plug must comply with the intended type of protection (e.g. dust proof, flameproof, etc.) and degree of protection (e.g. IP66/IP67 according to IEC EN 60529 or Type 4X according to NEMA 250). In particular, for explosion proof installation, remove the red temporary plastic cap and plug the unused opening with a plug certified for explosion containment with appropriate rating.


If required by national electrical codes, a circuit breaker or switch in the building installation, marked as the disconnect switch shall be in close proximity to the equipment and within easy reach of the operator.


In an industrial environment with extreme presence of EMI (electromagnetic interference), such as rock quarries, mines or large chemical plants, ABB recommends the use of noise filters on the DC power supply to the transmitter and signal isolators on the 4-20 mA output.

1. If applicable, install wiring with a drip loop. Arrange the drip loop so the bottom is lower than the conduit connections and the LLT100 housing.

2. Put back the housing cover, turn it to seat the O-ring into the housing and then continue to tighten by hand until the cover contacts the housing metal-to-metal. For Ex d (explosion proof) installation, see note Important – Securing the housing cover in flameproof areas on page 44.

5.5 Grounding

The LLT100 should be grounded or earthed in accordance with national and local electrical codes. Ground connection is mandatory for surge protector equipped devices in order to ensure proper functioning.

Protective grounding terminals (PE) are available outside and/or inside the housing of the LLT100. Both ground terminals are electrically connected and it is up to the user to decide which one to use. The most effective LLT100 case grounding method is direct connection to earth ground with impedance equal or less than 5 mOhm. The internal ground can be seen on Figure 32 on page 38.

Figure 31: External ground connection on LLT100 housing


5.6 Surge protector equipped terminal blockLLT100 must be connected using the grounding terminal (PE), by means of a short connection with the equipotential bonding.

Equipotential bonding conductor must have 4.00 mm2 of maximum cross-section.

WARNING – Bodily injury

For continued protection, the terminal board needs to be replaced if the installation shows any sign of damage resulting from direct or indirect lightning.

Important

Test voltage withstand capability can no longer be ensured when this protective circuit is used.

5.7 Common mode voltages

The LLT100 with surge protection will not work if exposed to common mode voltage in excess of the maximum allowed supply voltage.

6 Commissioning and operationOnce the LLT100 has been installed, it is put into operation by switching on the operating voltage.

Check the following before switching on the operating voltage:

– Process connections – Electrical connection

The LLT100 can then be put into operation.

6.1 Quick start guide

6.1.1 Setup procedure1. Connect the power and 4/20 mA wires to the LLT100 laser

level transmitter.2. For the standard LLT100 unit refer to section 5.8 Electrical

connections on page 38.3. Turn the power on.4. Establish communication with the LLT100 unit. Refer to

section 6.4 Optional integral LCD HMI with keypad (menu-controlled) on page 42 or through the HART protocol.

5. Set a vessel height that corresponds to your process.6. Set 4 mA and 20 mA set points defined as vessel full and

vessel empty. Refer to sections 6.11.1 Easy Setup on page 49 and 6.11.2 Device Setup menu on page 50.

7. Set the measurement mode, i.e. standard/normal, clear liquid and positioning or dust. Measurement mode is ap-plication oriented mode of operation and it is set accord-ing to the application the unit is used for. Refer to sec-tions 6.11.1 Easy Setup on page 49 and 6.11.2 Device Setup menu on page 50.

8. From the main menu, start the transmitter.

6.2 Configuration with the PC/laptop or handheld terminal

A graphical user interface (DTM) is required for configuration of the LLT100 using a PC or laptop. For operating instructions, please refer to the software description.

The LLT100 can be configured using one of the following devices:

– Any DTM based software for HART instruments configuration, providing it is compatible with EDD or DTM.

– Configuration of the LLT100 using the integral user interface (LCD HMI) with keypad (menu-controlled).

– Hand held terminals, provided the corresponding protocol has been downloaded and enabled in the terminal.

– Configuration of the parameters for the lower and upper range values (via the Zero and Span buttons), without an integral user interface (LCD HMI) (refer to section 6.13 Local push buttons functionality on page 63.

You can use a handheld terminal to read out or configure/calibrate the LLT100. If a communication resistor is installed in the connected supply unit, you can clamp the handheld terminal directly along the 4...20 mA line. If the line lacks a communication resistor, you will need to install one (min. 250 Ω). The handheld terminal is connected between the resistor and the LLT100, not between the resistor and the supply unit.

6.3 Factory settings

The LLT100 is calibrated at the factory. The LLT100 is delivered with the following default configuration:

Figure 40: Windowed front cover and LCD display

6.5.2 Through The Glass (TTG) activation considerations

The TTG technology allows the user to activate the keypad on the HMI without the need of opening the windowed cover of the LLT100. The capacitive pick-ups will detect the presence of your finger in front of the respective key activating the specific command. At the LLT100 power-on the HMI automatically calibrates its sensitivity. It is mandatory for the proper functioning of the TTG HMI that the cover is correctly tightened at power-on.

When the cover has been removed to access the communication board, it is recommended to power off and power-on again the LLT100 once the windowed cover has been set in place and properly tightened.

6.5.3 Activation procedure for TTG and LCD

The HMI features four keys (see Figure 39: LCD keypad on page 42) that allow the navigation through the various functions.

Press the Right arrow key within one second to access the HMI menu or press the Left arrow key to access the instantaneous diagnostic messages.

ImportantDo not operate the TTG display for 30 seconds after the LLT100 power-on. During this period of time, the LLT100 is calibrating the capacitive switches.

6.6 Analog and HART Communication models

If the measured distance falls within the values indicated on the name plate, the output current will be between 4 and 20 mA. If the measured distance falls outside the set range, the output current will be between 3.8 mA and 4 mA if the range is undershot or between 20 mA and 20.5 mA if the range is overshot (depending on the respective configuration).

6.7 Standard setting for normal operation 3.8 mA / 20.5 mA

In order to prevent errors in level measurements in the lower range, it is possible to set a “cut off point” via the optional LCD integral displays with keypad or via the graphical user interface.

A current that is less than 4 mA or grater than 20 mA may also indicate that the microprocessor has detected an internal error. In this case the alarm output can be configured both via the local LCD with keypad, via an external Hart hand held terminal or via a DTM based configuration tool.

6.8 Standard setting for error detection (alarm) 3.6 mA / 21 mA

The graphical user interface (DTM) or the LCD integral display, if installed, can be used to diagnose the error.



Important

A brief interruption in the power supply results in initialization of the electronics (program restarts).

IMPORTANT – Alarm current – Lower limit: 3.6 mA (configurable from 3.6 to 3.8

mA) – Upper limit: 21 mA (configurable from 20.5 mA to

22 mA), limited to 22 mA for HART Safety; apply for electronics release 7.1.15 or later)

Factory setting: high alarm current (21.0 mA)

During power-up period the LLT100 uses 21 mA.

Important – Securing the housing cover in flame-proof areasEach of the front faces of the electronics housing features a locking screw (hex-head socket screw) on the bottom side:

– Install the housing cover to the housing by hand-tightening it.

– Turn the locking screw counterclockwise to secure the housing cover. This involves unscrewing the screw until the screw head stops at the housing cover.

6.9 HMI menu structurePress the Right arrow key within one second to access the HMI menu or press the Left arrow key to access the instantaneous diagnostic messages.

The HMI menu is divided in the following sections which can be selected by pressing the Up arrow key and Down arrow key , once on the display, the desired sub-menu icon will be visualized. Confirm your selection with the Right arrow key [SELECT function].

Follow the instruction on the screen to perform the configuration of the different parameters.

The Easy Setup menu allows the verification and the parameterization of the basic configuration of the LLT100. The menu driven structure will guide you to the choice of the interface language, measurement mode, vessel height, sensor offset, 4–20 mA output (PV), the engineering units, the URV and LRV (Upper range value and lower range value), filling rate enabled or not and he tag number configuration.

The Device Setup menu allows the verification and the parameterization of the entire device. The menu driven structure includes the enabling the write protection, setting process variables (unit, LRV and URV), (linearization and output scaling (unit according to the measurement and LRV/URV). The last selectable sub-menu allows user to reset all the parameters to the default configuration.


The Display menu allows to set up different functions relevant to the display itself. The menu driven structure will guide you through the choice of some functional aspects as the display language and contrast. Moreover, it is possible to choose in detail what you want to see on the display: one or two lines with or without bar graph. Inside this menu there is the possibility of setting a protection password (security) and the display scaling (linearization type, unit, LRV, URV). Display revision number available.

The Process Alarm menu allows to the configure the process alarm. The menu driven structure will guide you through the choice of the fail safe functions such as the saturation limits and the fail level (upscale or downscale).

The Calibrate menu allows the local calibration of the transmitter. The menu driven structure will guide you through the choice of transmitter trimming (low or high), the output setting (set to 4 or 20 mA) and at the end you can reset these parameters (to factory transmitter trimming, to user transmitter trimming or to factory output trimming).

The Diagnostic menu allows you to monitor diagnostics messages related to level variables, output current and output percentage. The menu driven structure will also guide you through the loop test (set 4 and 20 mA and set the output value).

The Device Info menu gives you all the information about the device. The menu driven structure will show you the transmitter type, the hardware and software revisions, the high and low transmitter limits as well as the minimum applicable span.

The last section of this structured and driven menu, the Communication menu, gives you the possibility of changing the communication tag and the MULTI-DROP mode with HART address numbers of the device.



6.10 Measurement modes and filter options

Measurement mode Description Application

Standard The standard measurement mode is designed for maximized

precision under regular operating conditions.

Use for most solid applications and opaque liquid applica-

tions without dust or vapor.

Clear liquid This mode corresponds to the standard measurement mode

with an additional bottom-of-the-tank detection algorithm.

Use for transparent liquid applications in which the bottom of

the tank is visible through the liquid surface.

Positioning The positioning measurement mode features a special

calibration designed to work with retroreflector panel targets.

This mode also features an enhanced double-reflection

detection algorithm.

Use for positioning applications where the sensor aims at a

highly-reflective retroreflector panel.

Note: Only use when the target is a retroreflector panel. For

positioning applications with other types of targets, use the

standard measurement mode.

Dust & vapor This measurement mode uses an algorithm that improves

reliability in high dust and vapor conditions.

Use for applications with heavy dust or vapor conditions.

Note: To maximize precision, we suggest to use standard or

clear liquid mode in applications with neither dust nor vapor.

Filter option Description Application

Fill rate This corresponds to the maximum filling rate of the process.

The fill rate value is used to limit the maximum possible rate

of change of the level measurement reading during filling.

Warning: The fill rate must be set to maximum filling rate

of the process. Any change in level that is faster than the

entered fill rate will be smoothed out by the sensor.

Use in applications where heavy dust or vapor can severely

decrease the visibility of the level surface.

Use in applications in which the laser beam can be tempo-

rarily obstructed (by agitators, filling material, etc.).

Drain rate This corresponds to the maximum draining rate of the

process. The drain rate value is used to limit the maximum

possible rate of change of the level measurement reading

during draining.

Warning: The drain rate must be set to maximum draining

rate of the process. Any change in level that is faster than

the entered drain rate will be smoothed out by the sensor.

Use in clear liquid applications where the bottom of the tank

is visible through the surface.

Useful for liquid applications in highly reflective stainless

steel vessels.

Median filter LLT100 measurements can be noisy as a result of the

process.

The median filter is designed to filter out noisy measurement

spikes. The value entered corresponds to the median filter

buffer size. The last measurements are kept in the buffer and

the sensor returns the median value of the buffer. The buffer

size can range from 2 to 25.

Use for filtering out measurement noise in applications with

fast transients, such as rapidly varying processes, position-

ing applications, etc.

Use for discarding occasional false measurements resulting

from temporary laser beam obstruction, or any other occa-

sional unwanted reflection that might occur in the process.

Damping LLT100 measurements can be noisy as a result of the

process.

The damping filter is designed to smooth out measurement

noise. The value entered corresponds to the damping time

constant, and can range from 1 s to 3600 s.

Use for smoothing out measurement noise in applications

with slow dynamics (e.g. liquid with slow waves).


Filter option Description Application

No measurement period The no measurement period is a parametrizable amount of

time (between 2 s and 99999 s) during which the sensor, in

the absence of a reliable measurement, will predict the level

based on the current trend and/or fill rate.

Note: If the fill rate filter option is enabled, the sensor will

use the fill rate to predict the level measurement. Otherwise,

it will predict the level using the estimated current trend.

Note: After the no measurement period is over, if no reliable

measurement is still detected, the sensor will produce a

TARGET LOST error.

Use for agitated liquid applications. For these applications, a

value of the order of 10 s should be enough to guarantee a

good level reading stability.

Useful for applications where heavy dust or vapor can

severely decrease the visibility of the level surface. For these

applications, enter a value corresponding to the typical

surface obscuration time.

Useful for applications in which the laser beam can be tem-

porarily obstructed (by agitators, rotating blades, filling mate-

rial, etc.). For these applications, enter a value correspond-

ing to the typical laser beam obstruction time.

6.12 Custom linearization curve

The custom linearization curve function is always used to convert level to volume in all applications. In tanks with an irregular shape (Cylindrical lying tank or spherical tank), it can be registered to a freely identifiable transfer function with a maximum of 22 base points. The first point is always the zero point, the last point is always the final value. Neither of these points can be altered.

A maximum of 20 points can be freely entered in between.

These points have to be defined by extrapolating the tank filling table data and reducing them to 22 points. Once identified, the 22 points will need to be uploaded into the device by either using an HART hand held terminal or a proper configuration software like Asset Vision Basic.

6.12.2 Process alarmsThe Process alarm menu allows the complete configuration of the analogue output for the saturation and failure alarm. The output signal ranges from 4 to 20 mA when the process variable is within the calibrated span limits.

When the process variable (PV) is below the LRV (lower range value), the signal is driven to the “Low Saturation” limit (configurable).

When the PV is above the URV (upper range value), the signal is driven to the “High Saturation” limit (which is also configurable).

When the transmitter diagnostic detects a failure, the signal is driven upscale or downscale according to the user preferences (the failure direction is selected via the dip switches number 4 and 5 on the communication board). The exact value to which the signal is driven can be configured via the Process alarm menu (Alarm limits).

As a convention, the Low Alarm limit must be lower than the “Low Saturation” limit and the High Alarm limit must be higher than than the ‘High Saturation” limit.

6.13 Local push buttons functionality

The LLT100 allows local adjustments via the on-board non intrusive push buttons, when selected. The push buttons are located under the identification nameplate. To gain access to the local adjustments release the fixing screws of the nameplate and rotate clockwise the identification plate.

Attention – Potential damage to parts

Operating the push buttons with a magnetic screwdriver is forbidden .

Figure 43: Push button functionalities

6.14 Write Protection

Write protection prevents the configuration data from being overwritten by unauthorized users.

If write protection is enabled, the “Z” and “S” buttons (both internal or external) are disabled. However, it is still possible to read out the configuration data using the graphical user interface (DTM) or another, similar communication tool. The control unit may be leaded if required.

6.14.1 Write protection activation via external push button

When the transmitter features the external non-intrusive push buttons, the write protection function can be performed as follows:

1. Remove the identification plate (see Figure 40: Windowed front cover and LCD display on page 43) by releasing the holding screw located on the bottom left corner.

2. Use a suitable screwdriver to fully press down the switch.3. Turn the switch clockwise 90°.

IMPORTANT – Alarm current

To deactivate the switch, push it down slightly and then turn counterclockwise by 90°.

6.15 Correcting the 4-20 mA output range value / zero shift

During installation of the LLT100, zero shifts caused by mounting (e.g., a slightly oblique mounting position due to a remote seal, etc.) may occur; these must be corrected.

Important

The LLT100 must have reached its operating condition (approx. 30 seconds after startup in order to perform zero shift correction.

6.15.1 Setting the lower range value

1. Apply the lower range value (4 mA). The level must be stable and applied with a high level of accuracy << 0.05 % (observing the set damping value).

2. Press the “Z” button (external push button) or the “Zero” command on the connection board of the LLT100 for a few seconds. The output signal is set to 4 mA. The "span" remains unchanged.

Setting the lower range value by using the push buttons is possible if the write protection is not enabled. The level must be

6.16 Correcting the higher range value – Press the “S” button (under the identification plate on the

top of the LLT100, if present) or the “Span” internal button (on the connection board) for a few seconds to set the output to 20 mA.

It is also possible to align the digital PV value to zero. To do so

– Press the “Z” button or the “Zero” internal button (on the connection board). This functionality aligns the PV digital value to zero and if the calibrated span is zero based, the output is automatically set to 4 mA.

– Using the optional LCD with keypad (See section 6.2 Configuration with the PC/laptop or handheld terminal on page 40 for further information).

Important

The procedure described above does not affect the read measurement; it only corrects the analog output signal. For this reason, the analog output signal may differ from the physical measurement shown on the digital display or the communication tool.

– Press the “Z” button or the “Zero” internal button (on the connection board). This sets the output current to 4 mA. The digital PV value is automatically set to zero.

– To reset the PV zero bias setting, press the “S” button or the “Span” internal button (on the connection board).

ImportantWhen the LLT100’s digital PV value has been reset to zero following the above procedure, a zero bias/offset value is applied and stored in the LLT100 memory.

6.17 Configuring LRV and URV (4–20 mA ranging)

1. Adjust the level for the “lower range value” and wait approximately 30 seconds until it has stabilized.

2. Press the “Z” button or the “Zero” internal button (on the connection board). This sets the output current to 4 mA.

3. Adjust the level for the “upper range value” and wait approximately 30 seconds until it has stabilized.

4. Press the “S” button or the “Span” internal button (on the connection board). This sets the output current to 20 mA.

5. If required, reset the damping to its original value.

6. Record the new settings. The respective parameter will be stored in the non-volatile memory 10 seconds after the “Z” or “S” buttons are last pressed.

ImportantThis configuration procedure only changes the 4–20 mA current signal; it does not affect the physical values also shown on the digital display or user interface. After performing a correction, you must check the device.


7 Maintenance and service

7.1 Maintenance

The LLT100 is an optical electronic device with no moving parts. For this reason, no regular maintenance is required. When installed in a dusty environment, the LLT100 must be equipped with a dust tube. This will ensure long-term reliability and performance.

However, before installing the LLT100, it is recommended that the user perform a visual check on the lenses. If particles of dust are present on the lenses, use transmitter air to blow them off (see section 7.2 Cleaning the optical lens (all models except for hygienic) on page 65).

Periodic inspection of the lenses is recommended. The higher the dust level or environmental exposure, the more frequent these inspections should be.

The LLT100 does not contain field replaceable parts and there is no scheduled maintenance required to keep this product in compliance.

Opening the device will void the warranty.

Always turn the power off before removing or inspecting the LLT100.

Do not open the LLT100. All service or maintenance is to be performed at the factory by qualified ABB service personnel.

The communication box (HART) cannot be replaced in the field. Communication boxes cannot be exchanged from one LLT100 to another. In case of failure, the LLT100 transmitter has to be sent to ABB for repair and calibration.

7.2 Cleaning the optical lens (all models except for hygienic)

The optical lens is a sensitive component and must be cleaned with caution.

Clean the lens with transmitter air or if not sufficient, clean with alcohol and optical wipes.

When cleaning with air, make sure it is instrument grade at ambient temperature and humidity as well as oil free.

Opening the LLT100 will void warranty.

7.3 Cleaning of optical lens (hygienic model)

To clean the optical lens of the hygienic model

1. Remove the four set screws and clean them (refer to Figure 46: Hygienic flange-window assembly on page 66).

2. Dismantle the flange using two hook spanner wrenches with a diameter of 100 mm. These wrenches are to be provided by user.

Figure 45: Dismantle flange

3. Remove the O-ring of the window.

4. Clean the window, the O-ring, the flange adapter and the flange. Replace any damaged O-ring.

The window must not be dismantled.

5. Lay down the flange on the table and install the O-rings.

6. Screw the instrument on the flange by hand.

7. Make sure the O-ring of the window remains well in place.

8. Tighten firmly with the hook wrenches.

9. Screw the four set screws in place.
