2.1 Introduction to the transmitters

The Mobrey MSP400RH and Mobrey MSP900GH are 4–20 mA loop-powered transmitters, and are designed for liquid level measurement applications.

2.2 Theory of operation

February 2015

The Mobrey MSP400RH and MSP900GH ultrasonic liquid level transmitters are mounted above a liquid and use ultrasonic pulses to continuously measure the distance to the liquid surface. The electronics calculate the distance to the liquid level using the time delay between transmitting and receiving signals (Figure 2-1).

When programmed with the bottom reference of the application – usually the bottom of a tank – the transmitter calculates the liquid depth (level), and outputs the result as a 4–20 mA signal

and a digital HART

The MSP400RH and MSP900GH can also calculate contents volume or open channel flow, when programmed with further application information, and then outputs the result as a 4–20 mA signal and a digital HART signal.

2.3 Components of the transmitter

The transmitter has a housing containing advanced electronics to generate ultrasonic pulses, process the resultant signals, and provide a 4–20mA and HART output.

Removing the lid reveals terminals to connect a cable (not supplied) for the signal output and an external power supply. An LCD inside the enclosure displays the selected measurement. Programming is achieved using integral buttons or by remote communication using HART.

2.4 System architecture

The Mobrey MSP400RH and MSP900GH are two-wire, 24 Vdc loop-powered transmitters and can be connected to a direct current (dc) power source using two-core, shielded cable.

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. In this case,

communication is restricted to digital since the current is fixed to 4 mA.

Each transmitter can be configured locally using the membrane-buttons which are revealed after removing the housing cover. The transmitters can be configured remotely by using a Mobrey MCU900 Series control unit

A comprehensive specification for the Mobrey MSP400RH and MSP900GH is in the section “Specifications” on page 63.

Section 3: Installation

February 2015

3.2 Considerations before installation

The Mobrey MSP400RH and MSP900GH transmitters can be used for level and contents volume measurements in open or closed tanks, or for open channel flow measurements.

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 always 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.

3.2.1 Safety considerations

Guidelines

Reference Manual

IP2048/RM, Rev AA

1. Installation must be carried out by suitably trained personnel in accordance with the applicable code of practice.

2. 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.

3. The equipment must only be cleaned with a damp cloth.

4. 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.

5. 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).

6. Note that if the equipment is used in a manner not specified by the manufacturer, the protection afforded by the equipment may be impaired.

7. 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.

Reference Manual

IP2048/RM, Rev AA

3.3 Mechanical installation

Guidelines

1. Mount the transmitter above the liquid surface using the 2-inch thread provided, but not closer 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 11).

Optional flanges and bracket kits are available to help mounting. (See Rosemount Measurement product data sheet IP2045 for accessory part numbers.)

2. The transmitter should be mounted vertically to ensure a good echo from the liquid surface. The transmitter beam half angle of the is 6 degrees. (See Figure 3-1 on

page 10).

3. 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.

Section 3: Installation

February 2015

4. To avoid detecting unwanted objects in the tank or well, it is advisable to maintain a distance of at least 1.3 in. from the center line of the transmitter for every foot (11 cm per meter) range to the obstruction.

5. 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.

6. 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.

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

8. 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 11).

9. If the transmitter is used in environments where direct sunlight can cause high surface temperatures on exposed surfaces, a sun-shade is recommended.

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

3.3.1 Consider the liquid surface conditions

Guidelines

1. 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 foams.

2. Avoid mounting the transmitter directly over any inlet stream.

3.3.2 In-tank effects

Guidelines

1. Stirrers or agitators can cause a vortex. Mount the transmitter off-center of any vortex to maximize the return echo.

2. 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 56 or

page 93 for further information).

Reference Manual

IP2048/RM, Rev AA

3. 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.

4. 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.

Section 3: Installation

3.3.3 Mounting the transmitter above the liquid surface

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

Note

 The Mobrey MSP400RH and MSP900GH are designed to be mounted in a non-metallic

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

To help installation, flange accessories and bracket kits are available from Emerson Process Management (see Product Data Sheet IP2045 for accessory part numbers). 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.

February 2015

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. See Product Data Sheet IP2045 for accessory part numbers.

The bracket and disc dimensions are in Figure A-4 on page 69. The combined weight of bracket and disc is 16 oz (0,5 kg). For transmitter weight, see “Specifications” on page 63.

Bracket installation procedure

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).

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

4. Insert the transmitter into the disc.

5. Tighten to a torque of 1.5 lbf.ft. (2 Nm) using the hexagon. Do not use the transmitter housing to tighten.

Installing in a tank with a nozzle or stand-off

Installation procedure

1. Use PTFE tape on the screw thread of the transmitter (Figure 3-3).

2. If the tank has a flanged nozzle or stand-off:

a. Attach the transmitter to a non-metal instrument flange using the threaded

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

b. The instrument (accessory) flanges supplied by Emerson Process Management are

manufactured from PVC and are a full face design. Care must be taken when installing to a raised face mating flange on the tank or vessel to prevent distortion of the PVC

flange by over-tightening the bolts. c. Ensure the gasket is sitting correctly on the tank flange. d. Lower the assembled transmitter and instrument flange onto the tank flange, and

secure with appropriate bolting to a suitable torque for the flanges.

If mating to a raised face flange (RF) on the tank nozzle or stand-off, tighten to a

maximum torque of 10 lb-ft (13.6 N-m).

3. If the tank has a threaded nozzle or stand-off:

a. Attach the transmitter to the nozzle/stand-off using the threaded connection. b. Tighten to a torque of 1.5 lb-ft (2 N-m) using the transmitter’s hexagon.

Note

 If the transmitter face does not protrude into the vessel, note the dimensions in

Table 3-1 on page 3-13 for Figure 3-3, and ensure that the nozzle/vessel weld is smooth

and free from internal weld beads or other projections.

3.3.4 Open channel flow installations

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 (H

3.4 Electrical installation

3.4.1 Connecting the cable(s) to the transmitter

The Mobrey MSP400RH and MSP900GH are two-wire loop-powered transmitters accepting power supplies as follows:

 MSP400RH:12 to 40 Vdc (non-hazardous area only)

 MSP900GH:12 to 40 Vdc (non-hazardous area) or 12 to 30 Vdc (hazardous area)

Note

 To comply with the CSA approval, a transmitter must be powered from a Mobrey

MCU900 Series control unit, or a class 2 or separate extra-low voltage (SELV) source.

 Other devices may reset if connecting the transmitter to a multi-drop system while the

loop is powered. De-energize the loop to avoid devices being reset

Each transmitter is supplied with two cable entries. A suitable conduit system or cable gland must be used to maintain the weather-proof rating and hazardous area protection. Any unused entry must be sealed with a suitably rated blanking plug.

Reference Manual

IP2048/RM, Rev AA

A two-core, shielded/screened cable is required for external power supply and output signal connections. The cable is not supplied.

Connect the cable(s) to the transmitter

1. Make sure that the power supply is disconnected.

2. Undo the three cover screws and then lift the transmitter housing cover.

3. Pass the cable through the cable gland/conduit.

4. Connect the cable wires:

a. For the MSP400RH, see “Connecting the cable wires to the MSP400RH” on page 17. b. For the MSP900GH, see “Connecting the cable wires to the MSP900GH” on page 18.

5. Connect the cable shield/screen to a suitable ground (earth) at one end only.

6. Replace the cover, tighten the cable gland, and connect the power supply.

What to do after completing the cabling

To maintain the weather-proof rating and hazardous area protection of the transmitter, ensure all cable glands, blanking plugs, and seals are in good condition.

Relays

The MSP400RH 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 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 “Display and

push-buttons” on page 21.)

3.4.3 Connecting the cable wires to the MSP900GH

The MSP900GH is for intrinsically safe installations.

Note

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

Installation in a non-hazardous (ordinary location) area

Reference Manual

IP2048/RM, Rev AA

Connect the cable wires to the transmitter as shown in Figure 3-8 on page 19. See also “Wiring

to allow HART communications” on page 19 if HART digital communications is required.

Installation in a hazardous area

Connect the cable wires to the transmitter as shown in Figure 3-8 on page 19. See also “Wiring

to allow HART communications” on page 19 if HART digital communications is required.

When the MSP900GH is powered by a Mobrey MCU900 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.

3.4.4 Remote temperature sensor

The MSP400RH and MSP900GH accept input from a Mobrey Remote Temperature Sensor (see Product Data Sheet IP2045 for accessory part numbers).

This is a thermistor-based temperature sensor designed for use with the MSP400RH and MSP900GH.

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 MSP400RH or the MSP900GH.

3.4.5 Wiring to allow HART communications

If HART communications is required, a 250 Ohms (minimum), 0.25 W load resistor must be installed in the loop. (See “Dimension drawings” on page 68).

Note

 When the transmitter is used with a Mobrey MCU900 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.

Section 3: Installation

February 2015

Reference Manual

IP2048/RM, Rev AA

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.

3.4.6 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 “Dimension drawings” on page 68).

4.1 Overview

Mobrey MSP400RH and MSP900GH ultrasonic liquid level 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 navigated for programming the instrument

 and  steps.

using

The Integral Display Menu structure is shown in Appendix C: Integrated Display Menus.

Section 4: Starting up

February 2015

The 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. Default values are listed in Appendix D: Mobrey MCU900 Series.

The MSP400RH and MSP900GH are HART-enabled, allowing remote communications with the instrument. The transmitter can be programmed using a suitable HART-compatible master, or locally using the push-buttons provided inside the transmitter.

Note

 This section details the local programming. Refer to Appendix F: Configuring Using

HART if using a Mobrey MCU900 Series control unit or a Field Communicator.

4.1.1 Display and push-buttons

The integral display allows up to five characters. In running mode, the Primary Value (PV) measurement is displayed. In programming mode, data is displayed to assist with programming.

To the left of the main display are four arrow icons; one will be illuminated to indicate the selected duty.

To the right of the PV display on The MSP400RH 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).

4.1.2 Power up

When the power is turned on, the transmitter takes several seconds to initialize. The display will run 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.

On a new instrument aimed at a good target, the transmitter calculates a level reading based upon the default value for the bottom reference.

The duty icon against the letter L on the top plate, and the RL2 icon on The MSP400RH, will be illuminated. The RL1 icon on the MSP400RH may be illuminated, depending on the level calculated by the transmitter at this time.

The transmitter is now ready to be set-up with details of the application.

The transmitter may be programmed prior to, or after, installation. All programmed data is retained in the transmitter memory after the power is turned off.

IP2048/RM, Rev AA

4.1.3 Before programming

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.

 See the instructions below on how to use the push-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.

 Holding down the green button  scrolls through any option list.

 Pressing the red button  at any time will return you to the previous level in the menu.

 If the red button  is pressed after new data has been entered, the new data will

automatically be saved.

 The transmitter has a “re-set default values” routine that reloads the transmitter

memory with the factory default values. This will clear the memory of any previous data entered on site.

Section 4: Starting up

February 2015

4.2 Programming

Menu structures for this section are in Appendix C: Integrated Display Menus (page 75).

If using a HART Master Device for programming the MSP400RH or the MSP900GH, refer to the following sections for menu structures and parameters:

 Appendix D: Mobrey MCU900 Series (page 81)

 Appendix E: Field Communicator (page 85)

 Appendix F: Configuring Using HART (page 89)

4.2.1 Overview

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.

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

This is a manual navigation of

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.

Section 4: Starting up

February 2015

4.2.2 Selecting the duty

Screen display: dutY Factory default setting: Level

The arrow icon on the left side of the PV display indicates the selected duty. The MSP400RH and MSP900GH may be programmed to perform one of four duties:

1. Distance measurement.

4.2.6 Power Factor for the Flow Law

Screen display: P.FACt Factory default value: 1.000

This menu is offered if the selected duty is Flow 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 4-30). Alternatively, the power factor may be edited to suit a specific flow structure.

Note

 This menu option is in the programming menu. See Figure C-1 on page 76 for a map of

4.2.7 K-factor for the flow law

Screen display: SCALE Factory default value: 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 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.

4.2.13 Setting the output damping

Screen display: d Factory default value: 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.

Note

 A damping time of zero will not necessarily give an immediate response because the

MSP400RH and MSP900GH transmits nominally at once per second.

4.2.15 Setting the relay on and off points (MSP400RH)

The MSP400RH 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 energise at any value of PV, and de- energise 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 under Lost Echo (LE) or fault conditions. The relay de-energizes if the power fails.

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.

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.

5.5 False echoes under certain ambient operating conditions

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 transmitter 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 or a

Mobrey MCU900 Series Control Unit. The main descriptions for these parameters are on pages 137 to 138 in Appendix F: Configuring 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),

P048 is not equal to 6.0, the unit uses that value and Threshold 1

The MSP400RH and MSP900GH support HART communications, which may be used to program or interrogate the transmitters from any point on the two-wire loop. This section contains information on configuring the transmitters using a Field Communicator or a Mobrey MCU900 Series Control Unit.

Mobrey MCU900 Series Control Unit

February 2015

The product reference manual (IP2030/RM) provides full instructions on installation and operation of the control unit. There is also a quick installation guide (IP2030/QS). Both of these product documents are available in the Adobe PDF format, and can be downloaded from the Mobrey brand pages at www.emersonprocess.com.

A full menu map showing how to access transmitter parameters using the control unit’s menu system is in Appendix D: Mobrey MCU900 Series. For convenience, the parameter identification numbers (P*** and D***) are used in parameter headings and descriptions in this appendix.

When using the control unit, use the Enter ( ) key to start editing a configuration parameter and then use the arrow keys to change the setting. Changes are confirmed by pressing the Enter key, or abandoned by pressing the Esc key. Commands e.g. Set As Empty are run using the

Enter () key.

Field communicator

For convenience, Field Communicator fast key sequences are labeled “Fast Keys” for each software function below the appropriate headings. A full menu map showing how to access transmitter parameters using the Field Communicator is in Appendix E: Field Communicator.

Example software function

Fast Keys

When using a Field Communicator, some configuration changes are sent to the transmitter by pressing “SEND”.

1, 2, 3, etc.

Connect the Field Communicator leads to the transmitter, and turn on the Field Communicator by pressing the ON/OFF key. The Field Communicator will search for a HART-compatible device and indicate when the connection is made. If the Field Communicator fails to connect, it

indicates that no device was found. If this occurs, check the lead connections and re-try.

When the transmitter is shipped from the factory, the default factory setting for Base Units is “metric” or “imperial ft” depending on the model order code (see Product Data Sheet IP2045 for ordering information).

Note

 Keep a record of your programmed settings. Changing base units resets parameters to

their default factory settings in the appropriate units.
