2.1.1 Theory of operation

The Rosemount 3101, 3102, and 3105 transmitters are designed to be mounted above a liquid and use ultrasonic pulses to continuously measure the distance to the liquid surface. The microprocessor-controlled electronics calculate the distance to the liquid level from the time delay between the transmitting and receiving of the signals.

When programmed with the bottom reference of the application, usually the tank bottom (Figure 2.2), the transmitter calculates the liquid depth (level) and outputs the level as a

4–20 mA signal (and a digital HART

The 3101 calculates the level only and then outputs the result as a 4–20 mA signal.

The 3102 and 3105 can calculate level, contents (volume), or open channel flow, and then output the result as a 4–20 mA signal and a digital HART signal.

A LCD screen inside the enclosure displays the selected measurement. Programming is achieved using integral buttons inside the enclosure (all models), or by remote communication using HART (on the 3102 and the 3105 only).

2.3 System architecture

The Rosemount 3101, 3102, and 3105 are two-wire 24 Vdc loop-powered transmitters and can be connected to a direct current (dc) power source using two-core, shielded cable.

On The Rosemount 3101, the output is a 4–20 mA analog signal.

On The Rosemount 3102 and Rosemount 3105, the output can be a 4–20 mA analog signal and a digital HART signal.

Note

It is possible to use the multi-drop function with the HART protocol (Figure 2-3). In this case, communication is restricted to digital since the current is fixed to 4 mA

Each transmitter can be configured locally using the push-buttons (3101) or membrane-buttons (3102/3105) which are revealed after removing the housing cover.

The 3102 and 3105 transmitters can be easily configured remotely by using a Rosemount 3490 Series Control Unit. Alternatively, a Field Communicator, or a PC with AMS Suite: Intelligent Device Manager software can be used to configure each transmitter.

3.2 Considerations before installation

The Rosemount 3100 Series may be used for level and volume measurement in open- or closedtanks, or open channel flow measurement.

The glass-filled nylon housing version of the transmitter must be installed in a location where it is protected from ultraviolet radiation to prevent long term degradation of the plastics used e.g. shrouded from direct sunlight.

It is important to correctly position the transmitter for reliable ultrasonic level measurement. For maximum accuracy and stability of the level measurement reading, the transmitter should be shrouded from direct sunlight and radiated heat.

The transmitter may be site-tuned to deal with most application conditions, but it is recommended that the following guidelines be adopted where relevant.

Note

The Rosemount 3100 Series is designed to be mounted in a non-metallic fitting or flange.

The use of metallic fittings/flanges is not recommended.

Please see “Spare parts and accessories for the 3101/3102/3105” on page 90.

3.2.1 Safety considerations

 Installation must be carried out by suitably trained personnel in accordance with the

applicable code of practice.

 If the equipment is likely to come into contact with aggressive substances, it is the

responsibility of the user to take suitable precautions that prevent it from being adversely affected, thus ensuring that the type of protection is not compromised.

Aggressive substances are acidic liquids or gases that may attack metals or solvents that may affect polymeric materials.

Suitable precautions are regular checks as part of routine inspections, or establishing, from the material's datasheet, that it is resistant to specific chemicals.

 The equipment must only be cleaned with a damp cloth; do not use solvents.

 The equipment is not intended to be repaired by the user and is to be replaced by an

equivalent certified unit. Repairs should only be carried out by the manufacturer or approved repairer.

 The transmitter is Double Insulated, and therefore Protective Earthing is not required.

However, the cable shield/screen should be connected to a suitable ground (earth) at one end only (see “Connecting the cable(s) to the transmitter” on page 16).

 Note that if the equipment is used in a manner not specified by the manufacturer, the

protection afforded by the equipment may be impaired.

 To ensure electro-magnetic compatibility in any European member state, it should not

be installed in a residential area.

Note

It is not advisable to mount the transmitter in close proximity to a source of electrical noise such as a variable-speed drive or other high-powered electrical device.

than 12 in. (0,3 m) to the surface. The transmitter does not detect any liquid surface closer than 12 in. (0,3 m) to the transmitter face. (See “Mounting the transmitter above

the liquid surface” on page 12).

Optional flanges and bracket kits are available to help mounting (see “Spare parts and accessories for the 3101/3102/3105” on page 90).

 The transmitter should be mounted vertically to ensure a good echo from the liquid

surface. The transmitter beam half angle is 6 degrees (see Figure 3-2 on page 11).

 Obstructions in the tank, or well, may generate echoes which can be confused with the

real liquid surface echo. Obstructions within the beam angle generate strong false echoes. Wherever possible, the transmitter should be positioned to avoid false echoes.

 To avoid detecting unwanted objects in the tank or well, it is advisable to maintain a

distance sideways of at least 1.3 in. from the center line of the transmitter for ever y foot (11 cm per meter) range to the obstruction (see Figure 3-2 on page 11).

 No false echoes are generated if the transmitter is located near the side of the tank or

well, and the wall is smooth and free of protrusions. However, there will still be a reduction in the echo size. It is recommended that the transmitter be mounted no closer than 12 in. (0,3 m) to the wall to avoid a large reduction in the echo size.

 If the transmitter is mounted in an enclosed tank with a domed top, avoid mounting

the transmitter in the center of the tank roof because this could act as a parabolic reflector and create unwanted echoes.

Reference Manual

00809-0100-4840, Rev CB

 Avoid applications where heavy condensation could form on the transmitter face.

 If the transmitter is mounted in a stand-off or nozzle, the transmitter face should

protrude at least 0.2 in. (5 mm) into the tank. If this is not possible, see “Mounting the

transmitter above the liquid surface” on page 12).

 If the transmitter is used in environments where direct sunlight can cause high

temperatures on exposed surfaces, a sun-shade is recommended.

 Check that the maximum liquid level will not enter the 12-in. (0,3 m) blanking zone of

the transmitter.

3.3.2 Consider liquid surface conditions

 Foaming liquids can reduce the size of the returned echo because foam is a poor

ultrasonic reflector.

Mount an ultrasonic transmitter over an area of clear liquid, such as near the inlet to a tank or well. In extreme conditions, or where this is not possible, the transmitter may be mounted in a vented stilling tube provided that the inside measurement of the stilling tube is at least 4 in. (100 mm) and is smooth and free from joints or protrusions. It is important that the bottom of the stilling tube stays covered to prevent the ingress of foam.

Installation

Reference Manual

00809-0100-4840, Rev CB

 Avoid mounting the transmitter directly over any inlet stream.

 Liquid surface turbulence is not normally a problem unless it is excessive. The effects of

turbulence are minor, but excessive turbulence can be dealt with by fine-tuning the transmitter on site, if necessary.

3.3.3 Consider in-tank effects

 Stirrers or agitators can cause a vortex. Mount the transmitter off-center of any vortex

to maximize the return echo.

 If stirrer blades become uncovered, they create echoes as they pass through the

ultrasonic beam. The transmitter can learn to ignore these false echoes (see page 69 or

page 122).

 In tanks with rounded or conical bottoms, mount the transmitter off-center. If needed,

a perforated reflector plate can be installed on the tank bottom directly under the transmitter center line to ensure a satisfactory return echo.

 Avoid detecting pump casings, as the liquid falls away, by not mounting the transmitter

directly above pumps. If this is not possible, fine-tuning of the transmitter on-site may be required.

3.3.4 Mounting the transmitter above the liquid surface

A 2-in. thread is provided to mount the transmitter. The thread form is either 2-in. BSPT or NPT, and is clearly marked on the hexagon of the transmitter body.

To help installation, flange accessories and bracket kits are available from Emerson Process Management. The accessory flanges supplied are manufactured from PVC and are a full face design. Care must be taken when installing to raised face mating flanges on the tank or vessel to prevent distortion of the PVC flange by over-tightening the bolts. See “Spare parts and

accessories for the 3101/3102/3105” on page 90 for ordering information.

Note

The Rosemount 3101, 3102, and 3105 Transmitters are designed to be mounted in a

non-metallic fitting or flange. The use of metallic fittings/flanges is not recommended

Bracket mounting

The bracket kit contains a stainless steel angle bracket and PVC threaded disc, which may be used to mount the transmitter on a support over the liquid surface.

The bracket and disc dimensions are in Figure A-5 on page 86. The combined weight of bracket and disc is 16 oz (0,5 kg). For transmitter weight, see “Specifications” on page 77.

Installation instructions

1. Attach bracket to the disc using the three screws provided.

2. Attach the assembled bracket and disc to a rigid support over the liquid surface.

The bracket may be bolted to a suitable crossmember (structural section of steel). Ensure the transmitter is perpendicular to the surface to maximize the return echo size.

3. Use PTFE tape on the screw thread of the transmitter (Figure 3-4 on page 13).

4. Insert the transmitter into the disc.

5. Tighten to a torque of 1.5 ft-lb (2 N-m) using the transmitter’s hexagon.

3.3.5 Open channel flow installations (the 3102/3105)

There are normally two distinct parts to an open channel flow measurement system; the primary element (flow structure) and the secondary element (Head measurement instrumentation). For accurate open channel flow measurement, both parts of the system must be correctly installed. This section explains the important parts of installing the transmitter (secondary element). The flow structure (primary element) installation can be referenced in the British (BS3680) or ISO International standards.

Positioning of the transmitter is critical, and should be the correct distance upstream from the flow structure as stated in the relevant standard for your country. For example, in the ISO standards, the distance should be four to five times the maximum height of the water (Hmax) for a thin plate weir, or three to four times Hmax for a flume. For optimum accuracy, position the transmitter’s front face at a height equal to the sum of the maximum flow depth plus the transmitter deadband of 12.2 in. (300 mm) plus an extra 2 in. (50 mm).

Figure 3-5. Choosing the Height Position above a Flow

Reference Manual

A. Transmitter Front Face B. Hmax C. Transmitter Bottom Reference = Hmax + 12.2 in. (300 mm) + 2 in. (50 mm)

It is important that the bottom reference of the transmitter should be related to the datum of the primary measuring device (see Figure 3-6).

Relays

The 3102 has two integral relays which may be used for fault indication or control purposes. These relays are for light duty and should be used as signal relays only, with control functions being performed by external control relays.

Relay number 2 is defaulted as a 'fault' relay - normally energized - but may be re-configured on-site as a set-point relay if required.

Relay status indicators are on the LCD inside the housing (see “Integral display and buttons” on

page 24).

3.4.4 Connecting the cable wires to the Rosemount 3105

The Rosemount 3105 is for intrinsically safe installations. See Appendix B: Product Certifications for the safety approvals and control drawings.

Important

 Make sure the power supply is off when connecting the transmitter

February 2015

Installation in a non-hazardous (ordinary location) area

Wire the transmitter as shown in Figure 3-10 on page 20.

Installation in a hazardous area

When the 3105 is powered by a Rosemount 3490 Series Control Unit, no safety barriers are required as the output from the control unit is Intrinsically Safe.

If powering the transmitter from any other power supply, ensure a suitable Intrinsically Safe barrier is fitted in the non-hazardous (safe) area.

The barrier must be chosen such that its output parameters Uo, Io and Po are less than Ui, Ii and Pi of the transmitter (see Appendix B: Product Certifications).

The sum of the capacitance and the inductance of the transmitter and the connecting cable fitted must not exceed the maximum specified for the barrier chosen.

Note

Make sure that the instruments in the loop are installed according to intrinsically-safe field wiring practices and control drawings, when applicable

3.4.5 Remote temperature sensor

The Rosemount 3102 and Rosemount 3105 accept input from a Rosemount Remote Temperature Sensor (see “Spare parts and accessories for the 3101/3102/3105” on page 90).

This is a thermistor-based temperature sensor designed for use with the 3102 and 3105.

Full installation instructions are supplied with the temperature sensor, but it should be mounted out of direct sunlight in a position so that it can give a representative reading of the air temperature between the liquid surface and the transmitter.

Note

Do not connect any other temperature sensor to the Rosemount 3102 or 3105 Transmitters.

3.4.6 Wiring to allow HART communications

If HART communications is required (available on the 3102 and 3105 only), a 250 Ohm (minimum), 0.25 W load resistor must be installed in the loop.

Section 3: Installation

February 2015

Note

When the transmitter is used with a Rosemount 3490 Series Control Unit, there is no need to install an external load resistor in the loop because a suitable resistor is built in to the control unit (see “Load limitations” on page 83).

If the transmitter is being supplied through a safety barrier, ensure the type chosen will pass HART information.

After the load resistor is installed, a Field Communicator can be connected across the load resistor. It is the responsibility of the installer to ensure that any Field Communicator used

in the hazardous area is suitably certified.

Note

Make sure that the instruments in the loop are installed according to intrinsically-safe field wiring practices and control drawings, when applicable.

3.4.7 Lightning / surge protection and other loop devices

If the area is prone to lightning strikes or voltage surges, a suppressor device may be installed between the transmitter and the control unit.

If an additional loop-powered device or separately powered device is included in the two-wire loop, ensure the transmitter receives a minimum voltage of 12 Vdc. (See “Load limitations” on page 83).

4.2 Programming the Rosemount 3101, 3102, and 3105 Transmitters

Rosemount 3101, 3102, and 3105 Transmitters are operated from a menu of parameters, each held in a specific memory location within the transmitter. The memory locations may be pictured as a matrix, and are navigated for programming the instrument using

Each transmitter is pre-programmed at the factory with a value in each parameter location so that when the power is first applied, the transmitter gives a sensible reading.

This section details the programming using the buttons provided inside the transmitter. The Integral Display menu structure is shown in Appendix C: Integrated Display Menus.

Note

The 3102 and 3105 are HART-enabled, allowing remote communications with the instrument. For remote programming information, refer to Appendix F: Programming the 3102 and 3105

using HART

 and  steps.

4.2.1 Integral display and buttons

The integral display allows up to five characters. In the normal running mode, the display shows a measurement termed the Process Value (PV) of the transmitter. In programming mode, on the display is data to assist with programming.

To the left of the main display are four arrow icons (3102/3105 only); one of which will be illuminated to indicate the duty chosen by the user: Distance-to-surface (D), Level (L), Flow (F), or Contents (C).

To the right of the PV display on the Rosemount 3102 are two arrow icons that indicate the status of the transmitter relays. When illuminated, they indicate the relay contact is closed.

Under the PV display is a text string indicating the units of measurement. The transmitter will illuminate only those characters applicable to the units of measurement chosen.

To the right of the text string is an echo received icon. It is made up of three arc segments that continuously indicate the strength of the echo received (minimum, average, and good).

00809-0100-4840, Rev CB

Section 4: Starting up

4.2.2 What happens when powering up the transmitter

When the power is turned on, the transmitter takes several seconds to initialize. The display will run through a set-up routine, first illuminating all display characters, and then showing the software revision number. Finally, a full set of zeros is displayed while the microprocessor identifies the correct return echo. After these checks are complete, the display indicates the live measurement based upon the factory default values in memory.

When a new transmitter is aimed at a good target, the level reading is calculated using the default value for the bottom reference.

On the Rosemount 3102 and Rosemount 3105, the duty chosen icon next to letter L (Level) (and the RL2 icon on the 3102) will be illuminated. The RL1 icon on the 3102 may be illuminated, depending on the level calculated by the transmitter at this time.

The transmitter is now ready to be programmed with details of the application. It may be programmed on-site or prior to installation. All programmed data is retained in the transmitter memory after the power is turned off.

4.2.3 Considerations before starting the programming

February 2015

Important notes to help you program the transmitter

 Do not allow rain or water to enter the transmitter during programming or the circuit

boards may be damaged.

 The step-by-step instructions through is chapter show how to use the integral buttons

to navigate through the programming menu and select or enter application data.

 Push the buttons firmly, but not too hard to avoid damaging the circuit boards. Also, to

avoid entering incorrect data, do not push the buttons too fast.

 The 3102 and 3105 transmitters have a “load default values” routine that restores the

transmitter memory with factory default values. This will clear the memory of all previous selected or entered data.

To change the display units

1. Start from the PV display (see the note above).

2. Hold down the blue button

3. The display units will then change according to the following sequence:

3101****SC**: Metres to Feet, Feet to Inches, and Inches to Metres

3101****RC**: Feet to Inches, Inches to Metres, and Metres to Feet

4. Continue to hold down the blue button

above sequence after every three seconds.

5. Confirm the display units by releasing the blue button

The same units must be used when programming in the bottom reference and the 4 and 20 mA points. The 4–20 mA output may be set to operate over all or just a part of the total measuring range. There is no limit on the minimum span of the current output, although a span below 4 in. (100 mm) is not recommended. The 4 mA level may be set above or below the 20 mA level to suit the monitoring or control equipment.

4.3.2 First measurements (on the 3101)

With the transmitter installed and display units selected, the display will show what the instrument calculates as the liquid depth (level). This value is calculated by the microprocessor as being the difference between the distance-to-target being measured and the default value for the datum or bottom reference (b.rEF).

A. Transmitter Bottom Reference B. Distance-to-target C. Depth (Level)

Before changing any of the default values, press the blue button  to change the PV display to indicate distance-to-target, as measured by the transmitter from the transmitter face. This value is shown alternately with the text “diSt” to indicate the display is in distance mode. The calculation can be checked against a manual measurement if required.

Note

A useful feature at this stage is that the transmitter can be used as an electronic tape measure. With an empty tank or vessel, the transmitter will read the distance to the bottom of the tank. This distance can be noted and later used when setting b.rEF.

Press the blue button

 again to get to the echo size. This is a scale of 0 to 100. (It is possible to

record a value greater than 100). With the display in this mode, the central “:” cursor will flash once for every echo received, which under normal circumstances will be once per second.

Note

It is useful at this point to check that the maximum echo size available is being received. Adjust the position of the instrument until the highest echo size is continually shown. In most applications, the signal strength will vary over a wide range: 20 to 80.

Starting up

Press the blue button

 again to return to the original level reading and start the set-up routine,

4.3.5 Setting the output damping (on the 3101)

Screen display: d Default: 10

The damping value is a time constant in seconds, and is applied as smoothing to the level reading and the output current. A new value may be entered up to 999 seconds. A larger value will have the effect of smoothing out rapid changes of level, and smooth out the effects of turbulence and ripples on the liquid surface. (It would be unusual to select a value greater than 30 seconds).

A value of zero may be edited, in which case no smoothing is applied to the Current Output and transmitter readings immediately change the output.

Note

The Rosemount 3101 transmits nominally at once per second. Therefore, a damping time of zero will not necessarily give an immediate response.

4.3.8 Learn about echoes from false targets (on the 3101)

The Rosemount 3101 has an easy-to-use “Lrn” (Learn) routine that allows the instrument to learn up to two false echoes, which can then be ignored in future operations.

If the application is simple and there are no false echoes, press the green button integral display menu and return the instrument to indicating the level reading on the display.

If an echo other than the true liquid surface echo is detected and an incorrect level reading is indicated, the instrument can learn to ignore this false echo. The “Lrn” routine may be used at any time, either during or after setting-up or if a problem occurs later.

Note

See Figure C-1 on page 102 for a map of the programming menu structure and how to access all the menu options.

button

to exit the menu system and return to the PV display.

Note

If there are two false echoes stored (“Lrn2”), the transmitter will not allow another echo to be stored until the memory is cleared (see the next procedure).

When a false echo is stored, the transmitter sets up a 'window' around the false target and ignores any echo from that window, unless the echo received from the liquid surface is larger than the stored false echo. There may be no change in the transmitter output current while the liquid level moves through this window, which is equivalent to a distance of 8 in. (20 cm).

4.4 Programming the 3102 and 3105 using the integral display and buttons

Note

The Integral Display menu is shown in full in Appendix C: Integrated Display Menus.

If using a HART Master Device for remote programming of the 3102 or the 3105, refer to the following sections for menu structures and parameters:

 Appendix D: Rosemount 3490 Series Menus

 Appendix E: Field Communicator Menus

 Appendix F: Programming the 3102 and 3105 using HART

4.4.1 Overview of programming the 3102 or the 3105

Transmitter programming is most easily accomplished by first selecting the duty that the transmitter is to perform. After a duty is selected (see below), a “mini-wizard” programming assistant is invoked that asks only for information relevant to the selected duty. Entered data allows the mini-wizard to populate relevant parameters with application specific data and select the next step required to configure the transmitter.

February 2015

Note

It is advised to enter the “dutY” menu when programming the transmitter, initiating the mini-wizard to assist with programming.

After programming is complete, the data entered or calculated by the transmitter can be reviewed by going through the menu using the green button the menus, and all menus are shown regardless of the duty selected; the mini-wizard is only initiated when a duty is selected. Ignore menus that do not relate to your application.

Screen display: unitS Default: m (metric) or ft (Imperial)

Note

 The factory default units of measurement are dictated by the model part number

(see “Ordering information” on page 87)

The final option in each set is “none”, which appears as a blank screen. This option is available to the user who requires the display in units other than those available in the standard list of options. In this case, the user will need to scale the PV according to a suitable scaling factor (see

page 44). It is strongly recommended that the user makes a note of the scale factor and the

resultant units of measurement, and retain this on a label within the instrument at all times to avoid later confusion. (See parameters P000, P001, or P002 in the appendices).

This menu option only appears if a flow duty has been selected and a profile (e.g. “SPEC.C”) requires the manual editing of a power factor in the formula:

Flow Q = kh* (where * = the power factor)

The transmitter is pre-programmed with appropriate power factors for many standard flow profiles, and will automatically select the appropriate factor (See Table 4-1 on page 42). Alternatively, the power factor may be edited to suit a specific flow structure.

4.4.7 Setting the scaling factor (on the 3102/3105)

Screen display: SCALE Default: 1.000

Note

 If a flow duty has been selected, the value entered into this parameter is in effect the

K-factor in a flow law of the form Flow Q = kh*

If a Distance, Level or Contents (Volume) duty has been selected, the value entered into this parameter is a factor used to scale the measured distance, level, or volume.

For a Level or Distance duty, the scaling factor is normally left at the value calculated by the transmitter (depending upon previously entered data and duty selected), or the default value of

1.000.

For a linear Contents duty, enter a scaling factor to convert the level measurement to a contents (volume) measurement. If the measurement units are “m”, enter the volume contained in 1 m of liquid height in the tank. If the units of measurements are “ft”, then enter the volume contained in 1 ft. of liquid height in the tank.

4.4.13 Setting the output damping (on the 3102/3105)

Screen display: d Default: 3

The damping value is a time constant in seconds, and is applied as smoothing to the displayed PV and the output current.

A new value may be entered up to 999 seconds. A large value will have the effect of smoothing out rapid changes to the PV value, and smooth out the effects of turbulence and ripples on the liquid surface. (It would be unusual to select a value greater than 30 seconds).

A value of zero may be edited, in which case no smoothing is applied to the Current Output and transmitter readings immediately change the output. However, because the 3102 and 3105 transmit nominally at once per second, a damping time of zero will not necessarily give an immediate response.

Note

This menu option is in the programming menu. See Figure C-2 on page 103 for a map of the menu structure, showing how to access the menus.

4.4.14 Selecting the Lost Echo action (on the 3102/3105)

Screen display: AL Default: Hold

Faults are indicated by a fixed high or low output current, outside the 4–20 mA normal range, and which is selected by the model code that was chosen when ordering the transmitter (see the Special Alarms Options codes in the section “Ordering information” on page 87).

The exception is that a separate output current action can be user-selected for a lost echo condition, where a target echo is lost for 900 seconds or more.

There are three Lost Echo output current actions to choose from:

Hi The current on the two-wire loop increases to 21.75 mA (for the

Rosemount Standard) or 22.5 mA (for NAMUR NE43), depending on the full model code (see “Ordering information” on page 87). The current is fixed at that level until the correct target echo is recovered. The display flashes alternately “LE” and the maximum reading (equal to the Bottom Reference setting).

February 2015

Hold The current freezes at the last PV value and stays frozen until the correct

target echo is recovered. The display flashes alternately “LE” and the last known PV.

Lo The current on the two-wire loop decreases to 3.75 mA (for Rosemount

Standard) or 3.6 mA (for NAMUR NE43), depending on the full model code (see “Ordering information” on page 87). The current is fixed at that level until the correct target echo is recovered. The display flashes alternately “LE” and the minimum reading (“0000”).

Note

Table 5-1 on page 59 has a list of faults and alarms.

Faults (e.g. device malfunction) indicated on the output current have priority over the selected lost echo output current action.

Alarms e.g. outside temperature limits, and most faults, are indicated on the display. The 3102 can also indicate faults using its relay outputs.

The 900 seconds is factory set and is changeable in the field (see “Setting lost echo time (on the 3102/3105)” on page 64).

4.4.15 Setting the relay on and off points (on the 3102)

The Rosemount 3102 has two integral signal relays. Both relays are the SPST (Single Pole, Single Throw) type.

RL1 is factory-set to be a control relay. It may be set to energize at any value of PV, and de-energize at any other value of PV. Setting the on and off points to a common PV will turn the relay off. The on value may be greater or smaller than the off value, and vice-versa.

RL2 is factory-set to be a fault relay. In this mode, it de-energizes while there are Lost Echo (LE) or fault conditions.

The mode of RL2 may be changed to control mode by entering on and off values (use RL1 instructions below). In control mode, RL2 ceases to be a fault relay until the on and off values are reset to zero.

All relay set-point values must be entered in the units selected for the PV.

5.1 Safety messages

Explosions could result in death or serious injury.

 Verify that the operating environment of the transmitter is consistent with the

appropriate approval certifications.

 Before connecting a HART

-based communicator in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices.

 Do not remove the housing cover in explosive atmospheres when the circuit is alive.

Failure to follow safe installation and servicing guidelines could result in death or serious injury.

 Make sure only qualified personnel perform the installation.  Use the equipment only as specified in this manual. Failure to do so may impair the

protection provided by the equipment.

 Do not perform any service other than those contained in this manual unless you are

qualified.

High voltage that may be present on leads could cause electrical shock.

 Avoid contact with leads and terminals  Make sure the main power to the Rosemount 3101, 3102, and 3105 transmitter is off,

and the lines to any other external power source are disconnected or not powered while wiring the transmitter.

5.2 Servicing

The only maintenance required is to occasionally check the transmitter face to ensure it remains clean and check that the cover seal, wiring, and cable glands are in good condition.

There are no spare parts for the Rosemount 3101, 3102, and 3105. If a problem persists, contact Rosemount Inc. for advice.

5.3 Diagnostics for the 3101

No level reading

Reference Manual

Check that the instrument is ticking about once per second. If there is no ticking, the instrument should be replaced.

5.3.2 Error messages

Flashing “LE” with “0000”

The transmitter is not receiving a return echo, which could mean the liquid surface is poor or that it is beyond the range of 26 ft (8 m) of the instrument. Change the position of the transmitter or contact Emerson Process Management for information on longer range instruments

This means that the transmitter is not receiving a return echo, possibly because the liquid surface is poor or beyond the range (8m/26ft) of the instrument. Re-locate the instrument or contact Rosemount Inc. for details of longer range instruments.

Flashing “LE” with level reading

This means that the transmitter is no longer receiving satisfactory echoes from the liquid surface. This may be because of one of a variety of reasons, for example, excessive foaming, turbulence, or ullage vapors.

First, check that the transmitter face is free from contamination and condensation. The transmitter will operate with some condensation on the face, but excessive condensation may cause operational problems. If the vessel cannot be adequately vented to prevent condensation forming, contact Rosemount Inc. for alternative solutions.

Second, check that the instrument is still vertically aligned above the liquid surface and check the echo received size. If the echo size is small (<3), re-position the transmitter or modify the vessel for the transmitter to operate above a more acceptable area of the liquid surface.

Lost echo (LE) is signalled when there has been no return echo for 10 seconds. Within the 10 seconds, the output will remain fixed. If, after the 10 seconds, no satisfactory has been received,

The frequency at which the transmitter operates is automatically chosen by the microprocessor to ensure optimum signal size and performance.

“Auto” sets the frequency to obtain the best echo size and optimum performance. The actual frequency being used by the transmitter can be viewed in diagnostics (see page 60).

The limits of operating frequency are a function of the intrinsic properties of the transmitter itself, and may be set to operate at any frequency between 49 and 58 kHz.

The transmit frequency affects the quality of the echo being received, which may be used to improve a poor echo or reduce the quality of a false echo.

5.5.10 Setting the ambient temperature (on the 3102/3105)

Screen display: t Default value: Auto

The transmitter has an integral temperature sensor to measure the temperature of the air space surrounding it so that the speed of sound can be correctly computed for sending pulses. The distance-to-target is then calculated using the formula:

Distance to target = (Speed of Sound in air * Time for echo to return) / 2)

Auto indicates the transmitter is set to continuously measure the temperature using the integral temperature sensor. It may, occasionally, be necessary to over-ride this automatic monitoring and fix the temperature to be used in speed-of-sound calculations, for example if the air temperature is not uniform and the temperature being recorded is not the true air temperature.

5.6 False echoes under certain ambient operating conditions (on the 3102/3105)

In applications where elevated ambient temperatures of around 122 to 140 °F (50 to 60 °C) are experienced, together with poor liquid surface conditions (excessive surface agitation, foam, etc.), the 3102 and 3105 transmitters may see a false echo and report a false high level measurement.

To overcome this issue, the near zone threshold (Threshold 1 Size P048) was changed from software version V4.02 onwards to provide the following duty:

 Threshold 1 Size P048

The factory default value of this parameter is 6% (prior to V4.02 software this had a default value of 4%).

If Threshold 1 Size the value of the initial threshold in use at elevated temperatures to eliminate false high level readings.

If Threshold 1 Size the transmitter simultaneously adjusts the value of the initial threshold time in use at higher temperatures.

If Threshold 1 Size

P043 will be as programmed.

Time

Note that operating at elevated ambient temperatures over 140 °F (50 °C) may have an impact on the accuracy of the liquid level reading when the liquid level is within approximately 0.5 m of the transducer face. The accuracy may be reduced from ±2.5 mm to +2.5/-5.5 mm or, in extreme conditions, +2.5/-8.5 mm.

Note

Parameters P048 and P043 are accessible only when using a Field Communicator, Device Manager, or a Rosemount 3490 Series Control Unit. The main descriptions for these parameters are on pages 181 to 182 in Appendix F: Programming the 3102 and 3105 using HART.

P048 is equal to 6.0 (default), the transmitter automatically adjusts

P048 is set to 6.0 and Threshold 1 Time P043 is equal to 2.9 (default),
