1.0 Introduction

The MSP400 ultrasonic level transmitter is designed to be mounted above a liquid and will measure the distance to the liquid surface. When programmed with details of the vessel, sump or open channel, the MSP400 will compute level, contents or flow and give a 4-20mA signal proportional to the chosen variable. 2 relays are provided for control functions. Programming is achieved using integral push buttons or by remote communication using HART protocol.

MSP400 is a two wire 24V dc loop powered transmitter and may be connected to any suitable dc power source using 2 core shielded cable. The Mobrey MCU900 range of Control Units is designed to be used with the MSP400 transmitter in this way.

The MSP400 transmitter must not be mounted in a hazardous area, even if supplied from a protected power supply.

2.0 The MSP400RH ultrasonic level transmitter.

The transmitter operates over a range of 0.45m to 11m. When powered up the transmitter will give a 4-20mA signal on the two wire power cable over the factory default range :

4mA at 11m; 20mA at 0.45m. This range may be adjusted during commissioning. See section 4.0

Models covered in this manual :

MSP400RH - B28 MSP400RH - N28

The transmitter is mounted using the 2” thread provided. An optional mounting bracket kit is available on request. MSP-BRK2 (2” BSPT) or MSP-BRK3 (2” NPT).

3.0 Installation

Important safety notice : The MSP400 is designed for safe area use only, and must not be installed in a

hazardous area, even if the power is supplied through a barrier device.

General

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

applicable code of practice.

b. 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 – e.g. acidic liquids or gases that may attack metals or solvents that may

affect polymeric materials.

Suitable Precautions – e.g. regular checks as part of routine inspections or establishing from the

material’s data sheet that it is resistant to specific chemicals.

c. The equipment should only be cleaned with a damp cloth, do not use solvents.

d. 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.

3.1 Location of the MSP400RH transmitter

Correct location of the transmitter is essential for the reliable operation of any ultrasonic level measurement system. Whilst the transmitter may be site tuned to deal with most application conditions, it is strongly recommended that the following guidelines should be adopted wherever relevant.

3.1.1 General considerations

• The MSP400RH transmitter complies with the European Directive for Electro Magnetic Compatibility

(EMC) Class B. 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.

• The MSP400 should be mounted above the liquid surface using the “2” thread provided. To facilitate mounting, a bracket kit is available. See Section 3.2.

Note : The MSP400 is designed to be mounted in a non-metallic fitting or flange. The use of metallic fittings or flanges is not recommended.

• The transmitter should be mounted as near vertical as possible to ensure a good echo from the liquid surface and maximum echo size received. The beam angle (to the half power point) of the transmitter is 12 degrees inclusive.

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 such that false echoes are avoided. To avoid detecting unwanted objects in the tank or well, it is advisable to maintain a distance of at least 0.11m from the centre line of the transmitter for every metre range to the obstruction.

• If the transmitter is located near the side of the tank or well, there will be no false echo generated provided the wall is smooth and free of protrusions. However, there will still be a reduction in the echo size. To avoid large echo size loss, it is recommended that the transmitter never be mounted closer than 0.3m to the wall. Fatty, dirty or viscous liquids can cause a “scum line” to build-up on the tank or well wall. Avoid false echoes from this by enabling “scum line prevention” software in the MCU control unit.

i.e. D Min = 0.45m (18”)

D Max = 11m (433”) C = 0.3m (12”) min to 0.88m (36”)

• If the transmitter is mounted in an enclosed tank, avoid mounting the transmitter in the centre of the

tank roof as this could act as a parabolic reflector and create unwanted echoes. Avoid applications where heavy condensation could form on the transducer face.

• If the transmitter is mounted in a stand-off or nozzle, it is always preferable that the transmitter face

be at least 5mm proud of the stand-off such that it protrudes beyond the stand-off and into the tank. If this is not possible, see section 3.2.

• If the transmitter is used in environments where direct sunlight can cause very high surface

temperatures on exposed instruments, it is recommended that the installer should construct a suitable sun-shade to protect against this.

• Remember that the minimum operating range of the transmitter is 0.45m. The transmitter will not

detect any liquid surface closer than 0.45m to the transmitter face.

3.1.2 Liquid surface conditions

• Foaming liquids can reduce the size of the returned echo as foam is a poor ultrasonic reflector. It is

always preferable to 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 bore of the stilling tube is at least 100 mm (4”) and is smooth and free from joints or protrusions. It is also preferable that the bottom of the stilling tube does not become uncovered, thus preventing the ingress of foams.

• Beware of mounting the transmitter directly over any inlet stream.

• Liquid surface turbulence is not normally a problem unless it is excessive. In most cases, the effects

of turbulence are minor, with excessive turbulence being catered for by fine tuning the transmitter on site if necessary.

IP2046/IM

Nov 2006

3.1.3 In-tank effects

• Stirrers or agitators can cause a vortex. Always try to mount the transmitter off-centre of any vortex to maximise the return echo. As stirrer blades become uncovered they will create echoes as they pass through the ultrasonic beam. The transmitter can be tuned to ignore these false echoes on site.

• In non-linear tanks with rounded or conical bottoms, always mount the transmitter off-centre. In some cases, it may be desirable to install a perforated reflector plate on the tank bottom directly under the transmitter centre line to ensure a satisfactory return echo.

• Avoid mounting the transmitter directly above any pumps as the transmitter will detect the pump casing as the liquid falls away. If this is not possible, fine tuning on site may be required to ignore echoes from the pump casings.

3.1.4 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 installed accurately.

This manual explains some key aspects of the installation of the secondary element, in this case the ultrasonic transmitter. For full details of the installation of a primary element such as a flume or weir, reference should be made to the relevant British (BS3680) or International standard.

In the United Kingdom, Mobrey Ltd offers a complete installation and commissioning service for open channel flow measurement systems. For further information contact the sales office and/or refer to Mobrey’s ‘The Guide’.

Positioning of the transmitter is critical and should be the correct distance upstream from the flow structure as stated in BS3680 e.g. a distance of 4 to 5 times Hmax for a thin plate weir or 3 to 4 times Hmax for a flume. For optimum accuracy, the front face of the transmitter should be positioned at a height that is at least equal to the maximum flow depth plus the blanking distance of the transducer. A minimum distance of

0.46m is recommended.

Hmax + 0.46m

Hmax

It is important to note that the bottom reference of the transmitter should be related to the centre of the invert of the primary device, NOT the distance to the channel bottom directly below the transmitter.

In addition to the above, when setting the bottom reference on a ‘V’ notch weir it is important that the true invert of the weir is taken and not the meniscus liquid level, which may be 3 to 4mm (1/8”) above the true invert.

• The liquid surface at the point of measurement must have a stable, smooth surface and uniform approach velocity. It must not be affected by baffles, foam, hydraulic jumps or any other object likely to cause flow disruption.

• The primary element should be free from any situation where it is likely to ‘drown’ (refer to relevant standard for further information)

• The MSP400RH transmitter has integral temperature compensation and must be protected at all times from direct sunlight and any radiated heat. For maximum accuracy and stability of level measurement reading the transmitter should always be shrouded to prevent the incidence of direct sunlight. If the flow structure permits, mount the transmitter within the flow channel or chamber. Alternatively, the MSP400RH transmitter can accept an input from an external temperature sensor. See section 3.3.1.

If you are in doubt about any aspect of transmitter installation, contact Mobrey (Service

Division) who will be pleased to advise.

IP2046/IM

Nov 2006

3.2 Mounting the transmitter above the liquid surface.

A 2” thread is provided to mount the transmitter. The user should check the thread form, which will be either 2” BSPT (MSP400RH-B28) or 2” NPT (MSP400RH-N28). The thread form is clearly marked on the hexagon of the transducer body.

Note : The MSP400 is designed to be mounted in a non-metallic fitting or flange. The use of metallic fittings or flanges is not recommended.

To help installation, a bracket kit is available from Mobrey. This comprises a Stainless Steel angle bracket and PVC threaded disc which may be used to mount the MSP400 on a gantry or other support over the liquid level. Order part number MSP-BRK2 (BSP) or MSP-BRK3 (NPT). The bracket may be bolted to a suitable cross member above the liquid surface.

Ensure that the transmitter is perpendicular to the liquid surface to maximise the return echo size.

Check that the maximum liquid level will not encroach into the 0.45m blanking zone of the transmitter.

Note : To aid alignment, the echo size / signal strength can be displayed on the MCU900 control unit or on the MSP400RH transmitter display. Refer to section 4 for details.

Use PTFE tape on the screw thread, tighten to hand tight + ¼ turn, using the Hexagon.

When installing on a vessel which has a nozzle or stand-off, and the transducer face does not protrude into the vessel, note the dimensions in the diagram below and always ensure that the nozzle/vessel weld is smooth and free from internal weld beads or other projections.

Use hexagon to tighten to hand tight + ¼ turn DO NOT USE HOUSING TO TIGHTEN.

3.3.1 External temperature sensor

The MSP400RH transmitter will accept an input from a Mobrey external temperature sensor.

Order part number MSP-RTP. This is a thermistor based temperature sensor specifically designed for use with the MSP400RH transmitter. Full installation instructions are supplied with the temperature sensor, but note that it should be mounted out of direct sunlight in a position such that it can give a representative reading of the air temperature between the liquid surface and the MSP400RH transmitter.

3.3.2 After completing the wiring

Ensure all cable glands / blanking plugs and seals are in good condition after wiring to maintain the weatherproof rating of the transmitter.

Check that the cover seal is in good condition and not twisted or misaligned in the seal location groove. When replacing the cover, tighten the 3 cover screws evenly to exert uniform pressure on the cover seal.

IP2046/IM

Nov 2006

3.3.3 Relays

The MSP400RH transmitter has 2 integral relays which may be used for control purposes. These relays are 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 energised, but may be reconfigured on site as a set point relay if required.

3.4 Additional components in the two wire loop.

3.4.1 Lightning / surge protection and other loop devices

It is allowable to fit loop powered or separately powered devices in the two wire loop provided that the transmitter receives a minimum voltage of 12V dc at 21 mA loop current.

If the area is prone to lightning strikes or voltage surges, fitting of a suppressor device is desirable between the transmitter and the control unit.

3.5 Wiring to allow HART communication

If it is intended to use HART digital communications with the MSP400RH transmitter, a 250 Ohm 0.25W load resistor must be installed in the loop.

When used with the Mobrey MCU900 family of Control Units, there is no need to install an external load resistor in the loop as there is a suitable resistor built in to the Control Unit.

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

Once installed, a HART communicator can be connected across the load resistor, or across the loop at any point downstream of the load resistor.

IP2046/IM

4.0 Commissioning, programming and operation

The MSP400 operates from a menu of parameters, each held in a specific memory location within the instrument. The memory locations may be pictured as a matrix, and the user navigates to each parameter to programme the instrument using ↓ and → steps. Refer now to the Main Menu structure shown in Appendix A

The MSP400 leaves the factory pre-programmed with a value in each parameter location such that , when the power is first applied, the instrument will give a sensible reading. A list of default values is given in the parameter listing in Appendix B.

The MSP400 is HART enabled, allowing remote communications with the instrument. The instrument can therefore be either programmed using a suitable HART compatible master, or may be programmed locally using the push buttons provided inside the instrument. For details of local programming, continue reading this section. For details of HART communications, refer to Appendix D.

4.1 Display and push buttons.

The main display allows display of up to 5 characters, which in the normal run mode will be the measurement, termed the Primary Variable (PV) of the instrument, or in the programming mode will be data to assist in programming.

To the left of the main display are 4 arrow icons, only one of which will be illuminated at any one time to indicate the duty chosen by the user.

To the right of the main display are 2 arrow icons which indicate the status of the transmitter relays. When illuminated, they indicate that the relay contact is closed.

Under the main display is a text string which allows display of the units of measurement. The instrument will illuminate only those characters applicable to the units of measurement chosen.

To the right of the text string is an echo received icon made up of 3 arc segments which continuously indicate the strength of the echo received (minimum, average and good)

IP2046/IM

Nov 2006

4.2 Power up

On power up, the MSP400 will take a few seconds to initialise. The display will run through a set-up routine, first illuminating all display characters then showing the software revision number. Once checks are complete, the display will show the Primary Variable (PV) determined based upon the factory default values in the memory.

On a new instrument aimed at a good target, this will be what the MSP400 calculates as 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 will be illuminated. It is possible that the RL1 icon may be illuminated depending upon the level calculated by the MSP400 at this time.

The MSP400 is now ready for use, and the next step is to programme the unit with details of the application.

The MSP400 may be programmed either in-situ or prior to installation. All programmed data is retained in the MSP400 memory after power off.

4.3 Programming- Important notes to help you programme the MSP400

• Do not allow rain or water to enter the MSP400 whilst programming or damage to the circuit boards

will occur.

• Use the push buttons as instructed below to navigate through the programming menu and select or

enter application data. It is recommended that use of the push buttons is firm but not overly so to prevent damage to the circuit boards below, and that the user should not press buttons too fast to avoid incorrect data entry. Simply holding down the green button ↓ will automatically scroll through any option list without the need for repeated pressing of the button.

• Pressing the red button ↵ at any time will step the user back to the previous level in the menu. Note, if the red button ↵ is pressed after a menu option selection has been made or new data has been entered, this option selection or new data will automatically be saved.

• Whilst programming should be simple and intuitive, it may be that the user wishes to start again or may wish to clear the memory of site entered data from a previous application. The MSP400 has a “re-set default values” routine which allows the user to reload the MSP400 memory with the factory default values as shown on the menu structure. Refer to section 4.7.10.

IP2046/IM

Nov 2006

4.4 Setting up for the chosen application - the Main Menu.

Refer now to the main menu structure chart in Appendix A.

It is important to note that MSP400 programming is most easily accomplished by first selecting the duty the transmitter is to perform. Once a duty is selected (see section 4.4.1), a “mini-wizard” programming assistant is invoked and the user is thereafter only asked for information relevant to the duty chosen. As the user is guided through the menu, data input allows the mini-wizard to populate relevant parameters with application specific data in the background, and then select the next step required to configure the transmitter for the chosen application.

The user is strongly advised to enter the duty menu whenever programming the MSP400, thus invoking the mini-wizard which will assist programming.

Once programmed, it is possible to review the data entered into or calculated by the MSP400 by stepping through the main menu using the green button ↓.

Note however that this will be a manual navigation of the MSP400 menu, and that

all

menu items will be shown in this procedure, regardless of the duty chosen; the mini-wizard is only invoked if the user enters and scrolls through or selects/refreshes a duty choice. In a manual navigation down the main menu, simply ignore those menu items shown that do not relate to your application.

4.4.1 Selecting the duty: Screen display: dutY

Factory default setting: Level

The MSP400 may be programmed to perform one of 4 duties:

• Distance measurement

• Level measurement (factory default setting)

• Flow measurement

• Contents measurement

To change the duty:

a) Press the green button ↓ to display the “dutY” menu entry screen.

b) To confirm or change the duty from Level to one of the other duties, thus invoking the mini-wizard,

press the blue button → to enter the “dutY” menu. Press the blue button → again to allow change of the duty. The current duty will now be flashing, indicating it may be confirmed or changed.

c) Press the green button ↓ to scroll through the list of available duty options, or press the red button ↵ if

the duty displayed is correct

d) Once the desired duty is shown (flashing) on the display, press the blue button → to select this duty. It

will now stop flashing.

e) If the chosen duty is incorrect, the edit sequence for the duty can be re-started by pressing the blue

button → again.

If the chosen duty is correct, press the red button ↵ to save the duty to memory and automatically scroll on to the next main menu option: units.

Note that the arrow icon to the left of the display will now show the duty chosen and saved.

IP2046/IM

Nov 2006

4.4.2 Selecting the units of measurement Screen display: unitS Factory default setting: MSP400RH-B28 m MSP400RH-N28 ft

i) Note that the factory default units of measurement are dictated by the model type, which may be Imperial (ft) or Metric (m). The user can reconfigure a Metric unit to be an Imperial or vice-versa by changing the base units (b.unit) of the MSP400 - refer to section 4.7.11

ii) Note that changing the base units will cause the MSP400 to re-start with factory default values in all other parameters.

Changing base units after programming the MSP400 will cause all programmed data to be overwritten with factory default values.

The MSP400 is pre-programmed with selected units of measurement for each of the duties available :

• Distance and Level measurement

m , ft, in, none

• Flow measurement

l/s, l/m, m3/hr, gal/s, gal/m, ft3/m (cfm), ft3/hr, none

• Contents measurement

l, m

gal, ft

To change the units of measurement:

a) Press the green button ↓ to display the “unitS” menu entry screen. If metres are the chosen units of

measurement, as indicated by the small “”m” below the word “unitS” press the green button ↓ to continue commissioning.

b) To change the units of measurement from metres to one of the other options, press the blue button →

to enter the “unitS” menu. Press the blue button → again to allow change of the units of measurement. The current unit of measurement will now be flashing, indicating it may be changed.

c) Press the green button ↓ to scroll through the list of available duty options.

Notes. i) The MSP400 will offer a selection of units of measurement relevant to the chosen duty as shown in the option table above. The final option in each set is “none”, which appears as a blank screen. This option is available to the user who requires to display in units other than those available in the standard option table. In this case, the user will need to scale the PV according to a suitable scaling factor - refer to section 4.4.6 It is strongly recommended that the user make 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.

ii) When using the green button ↓ to scroll through the units of measurement options, allow 2-3 seconds after each button press for the MSP400 to check and display the selection. Pressing the green button ↓ continuously simply continues scrolling around the units of measurement option loop.

d) Once the desired unit of measurement is shown (flashing) on the display, press the blue button → to

select this option. It will now stop flashing.

e) If the chosen units of measurement are incorrect, the edit sequence for the units of measurement

can be re-started by pressing the blue button → again.

If the chosen units of measurement are correct, press the red button ↵ to save the units of measurement to memory and automatically scroll on to the next main menu option: b.rEF.

liquid level

To change the bottom reference:

a) Press the green button ↓ to display the current “b.rEF” menu entry screen.

b) Press the blue button → to enter the “b.rEF” menu and to display the current bottom reference in use.

It is quite unlikely that the factory default value for bottom reference will suit your application. To edit the bottom reference, press the blue button → to enter the editing mode. The leading digit of the current bottom reference will now be flashing, indicating it may be changed.

c) Use the green button ↓ to edit the value of the leading digit.

Be careful not to enter a value greater than the maximum range of the MSP400: 11m or 36ft.

The value of the leading digit should therefore be 1 or 3 as a maximum, depending upon the units of measurement chosen earlier.

Once correct, use the blue button → to select the next digit and then the green button ↓ to edit as before, or the blue button → to move to the next digit. Continue this sequence until all 5 digits are correct.

d) Press the blue button → a final time to confirm the new value. None of the digits should now be

flashing.

e) If the new bottom reference value is incorrect, the edit sequence for the bottom reference can be re-

started by pressing the blue button → again.

If the new bottom reference is correct, press the red button ↵ to save the new value to memory and automatically scroll on to the next main menu option:

Note: If the user has chosen a duty of Flow or Contents, the next menu option offered will be “ProF”. Refer now to sections 4.4.4 to 4.4.9.

If the user has chosen a duty of Level or Distance, the next menu option offered will be “4”. Skip sections 4.4.4 to 4.4.9 and refer now to section 4.4.10.

TIP

: a feature of the MSP400 useful at this stage is that it can be used as an electronic tape measure.

With an empty tank or vessel, select Distance as the duty and the MSP400 will read the distance to the bottom of the tank. This can be noted and used when setting b.rEF

IP2046/IM

4.4.4 Selecting the correct Profile algorithm. Screen display: ProF Factory default value: Linear

This selection is offered only if the user has chosen a duty of Flow or Contents, or is shown when manually navigating the main menu - ignore if duty chosen is Level or Distance.

The MSP400 is pre-programmed with a selection of popular profiles which are mathematical formulae to convert a linear level reading to a flow or volumetric PV. Once converted, the 4-20mA and the display of the unit will operate according to the flow or volumetric PV.

4.4.12 Setting the damping applied to the output Screen display d Factory default value 3

The damping value entered is actually a time constant in seconds which is applied as smoothing to the displayed PV and current output. A new value may be entered up to a maximum value of 9999 seconds. A large value will have the effect of smoothing out rapid changes of current output and will also smooth out the effects of turbulence and ripples on the liquid surface.

Note, it would not normally be necessary to select a value greater than 30 seconds.

Alternatively, a value of zero may be entered in which case no smoothing is applied and changes in reading immediately change the current output.

Note, as the MSP400 transmits a pulse at nominally once per second, a damping time of zero will not necessarily give an immediate change in output.

To edit the damping value:

a) Press the blue button → to enter the damping menu and to display the current value in use. If this is

correct, press the green button ↓ return to the main menu. If the damping value is to be edited, press the blue button → again to allow editing

The dead band is the region below the MSP400 transmit face in which no measurements can be made. This is also sometimes known as the Blanking or Blocking zone, and is a feature of all Ultrasonic level transmitters, with a value dependant upon certain intrinsic properties of the transmitter itself.

The user should never reduce the dead band below the factory default minimum value unless advised to do so by the manufacturer.

A larger value may be entered to elimate echo processing of echoes from false targets.

Note however, that any real echos in the dead band will also now be ignored.

IP2046/IM

Nov 2006

To edit the dead band:

a) Press the blue button → to enter the dead band menu and to display the current value in use. If this is

correct, press the red button ↵ return to the main menu. If the dead band is to be edited, press the blue button → again to allow editing

The leading digit of the dead band value will now be flashing, indicating it may be changed.

b) Use the green button ↓ to edit the value of the leading digit.

before, or the blue button → to move to the next digit. Continue this sequence until all digits are correct.

d) Press the blue button → a final time to confirm the new value. None of the digits should now be

flashing.

If the new dead band is incorrect, the edit sequence can be re-started by pressing the blue button → again.

If the dead band is correct, press the red button ↵ to save the new value to memory and automatically scroll on to the next main menu option: “F”

4.7.4 Setting the Frequency Screen display “F” Factory default value: Auto

The frequency at which the MSP400 operates is automatically chosen by the microprocressor to ensure optimum signal size and performance.

Auto shows that the MSP400 will automatically set the frequency to obtain the best echo size and optimum performance. The actual frequency being used by the MSP400 can be viewed in diagnostics. See 4.5.5

The limits of operating frequency are a function of the intrinsic properties of the transmitter itself. The MSP400 may be set to operate at any frequency between 49 and 58 kHz

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

To change the frequency:

a) Press the blue button → to enter the frequency menu and to display the current value in use. If this is

correct, press the red button ↵ return to the main menu. If the frequency is to be changed, press the blue button → again to allow editing

If the valid echo count is incorrect, the edit sequence can be re-started by pressing the blue button → again.

If the valid echo count is correct, press the red button ↵ to save the valid echo count to memory and automatically scroll on to the next main menu option: “SPi”

IP2046/IM

Nov 2006

4.7.7 Setting the Spike rejection Screen display “SPi” Factory default value: 0 (disabled)

In applications with high levels of acoustic or electrical noise, a spike could incorrectly trigger the echo detection system. In such cases, the value of SPi can be increased (in the range 0-100) which has the effect of rejecting such spikes. The user may have to try several different values to determine the best option.

To change the spike rejection:

a) Press the blue button → to enter the spike rejection menu and to display the current value in use. If

this is correct, press the red button ↵ return to the main menu. If the spike rejection is to be changed, press the blue button → again to allow editing

The spike rejection currently in use will now be shown flashing on the display.

b) Use the green button ↓ to scroll through the options available (1 - 100 in pre programmed steps)

c) Use the blue button → to select the chosen spike rejection.

If the new spike rejection is incorrect, the edit sequence can be re-started by pressing the blue button → again.

If the spike rejection is correct, press the red button ↵ to save the new spike rejection to memory and automatically scroll on to the next main menu option: “t”

4.7.8 Setting the Temperature Screen display “t”

Factory default value: Auto

The MSP400 has to know the temperature of the air space through which it is sending pulses so that the speed of sound can be correctly computed. The distance to target is then calculated using the formula

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

The MSP400 is fitted with an integral temperature sensor which continuously monitors the air temperature around the transducer.

Auto indicates that the MSP400 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 SoS computations, for example if the air temperature is not uniform and the temperature being recorded is not representative of the true air temperature.

To edit and fix the temperature :

a) Press the blue button → to enter the temperature menu and to display the current value in use. If this

is correct, press the red button ↵ return to the main menu. If the temperature is to be edited, press the blue button → again to allow editing

The leading digit of the temperature will now be flashing, indicating it may be changed.

b) Use the green button ↓ to edit the value of the leading digit.

c) Once correct, use the blue button → to select the next digit and then the green button ↓ to edit as

before, or the blue button → to move to the next digit. Continue this sequence until all digits are correct.

d) Press the blue button → a final time to confirm the new value. None of the digits should now be

flashing.

IP2046/IM

Nov 2006

If the new temperature is incorrect, the edit sequence can be re-started by pressing the blue button → again.

If the temperature is correct, press the red button ↵ to save the new value to memory and automatically scroll on to the next main menu option: The next option will be “t.CAL” if the MSP400 is using the Mobrey remote temperature probe MSP-RTP to monitor the air temperature.

If no external temperature probe is connected the next menu option will be “Ld.dEF”. Refer now to Section 4.7.10.

4.7.9 Temperature calibration Screen display “t.CAL”

This menu option is only displayed if the MSP400 is using the Mobrey remote temperature probe MSP-RTP to monitor the air temperature. Remote air temperature measurement is only possible with the Mobrey MSP-RTP. This is a negative temperature co-efficient (NTC) thermistor design. Due to the effects of cable length and electronic component tolerances the MSP-RTP air temperature measurement could be up to +/- 0.5°C in error. This menu option allows the user to trim the recorded temperature to match the users own reading.

To edit and fix the temperature :

a) Press the blue button → to enter the temperature calibration menu and to display the current value in

use. If this is correct, press the red button ↵ return to the main menu. If the temperature is to be calibrated, press the blue button → again to allow calibration.

The leading digit of the temperature will now be flashing, indicating it may be changed.

b) Use the green button ↓ to edit the value of the leading digit.

c) Once correct, use the blue button → to select the next digit and then the green button ↓ to edit as

before, or the blue button → to move to the next digit. Continue this sequence until all digits are correct.

d) Press the blue button → a final time to confirm the new value. None of the digits should now be

flashing.

If the new temperature is incorrect, the edit sequence can be re-started by pressing the blue button → again.

If the temperature is correct, press the red button ↵ to save the new value to memory and automatically scroll on to the next main menu option:

4.7.10 Loading factory default values Screen display “Ld.dEF”

It may occasionally be necessary to re-set the MSP400 parameters to factory default values, particularly if the user is unsure of data already changed and held in the transmitter.

Note : Re-loading factory defaults will overwrite all parameters and all site entered data will be lost.

To ensure that this operation is not initiated by accident, a specific push button sequence is necessary to load factory defaults.

IP2046/IM

Nov 2006

To load factory default values:

a) Press the blue button → to enter the load defaults menu and display “Ld.dEF”

b) Press the blue button → for at least two seconds to flash the screen message “SurE”.

c) Press the blue button → again to acknowledge the message and stop the message flashing.

The user can now abort by pressing the blue button → again to return to the start of the menu, allowing moving on to “b.unit” (refer to section 4.7.11) or may continue on and load factory defaults.

d) To load factory defaults, press and hold both the blue button → and the red button ↵ together for at

least 2 seconds.

The screen will now flash the message “b.units” and will reload all factory default values. The MSP400 will now automatically re-start as if it were a new instrument on first power-up.

4.7.11 Changing the base units Screen display “b.unit” Factory default: MSP400RH-B28 metric (m) MSP400RH-N28 imperial (ft)

The MSP400 may be reconfigured to operate in a choice of base units:

Metres Feet Inches

Note: If the base units are changed, the MSP400 will automatically re-start as if it were a new instrument on first power-up, but will default to the chosen base units and will load factory default values into all other parameters.

To change the base units :

a) Press the blue button → to enter the base units menu and to display the current units in use. If these

are correct, press the red button ↵ return to the main menu. If the base units are to be changed, press the blue button → again to allow editing

The base units currently in use will now be shown flashing on the display.

b) Use the green button ↓ to scroll through the 3 options available .

c) Use the blue button → to select the chosen base units.

If the base units are incorrect, the edit sequence can be re-started by pressing the blue button → again.

If the base units are correct, press the red button ↵ to save the new base units and automatically re-start the MSP400.

5.0 Maintenance

There is no routine maintenance required for the MSP400RH other than an occasional check to ensure that the front face of the transmitter is clean and that the cover seal and all wiring / cable glands are in good condition.

APPENDIX D

HART COMMUNICATIONS WITH THE MSP400

D 1.0 Overview

The MSP400 ultrasonic level transmitter supports HART communications, which may be used to programme or interrogate the transmitter remotely from any point on the 2 wire loop.

Any HART compatible communication device may be connected across the loop and, if loaded with the Device Description (DD) of the MSP400 transmitter, will have full access to the all of the parameters of the instrument as shown in D 3.0 If the communication device is not loaded with the MSP400 DD, then access to the Universal and some Common Practice commands is possible in accordance with HART convention.

The MSP400 may be used with the Mobrey MCU900 Series of control units. MCU900 will supply the 24V dc loop power to the MSP400 and provide control functionality using the 4-20mA signal from the transmitter. The MCU900 control unit has HART communications capability and access to all of the parameters of the MSP400 as shown in D3.0.

The Mobrey PC software “DDConf” is also available, allowing a computer fitted with a HART modem to communicate with and re-programme the MSP400 transmitter. Note : A HART modem is supplied with the DDConf software.

D 2.0 Wiring

Wiring for HART communications is no different to that of 4-20mA instruments, except that the loop must contain a resistance of at least 250 Ohm. This resistance may be achieved by a combination of wiring resistance and any other loop instruments, or may be achieved by the inclusion of a suitable 250 Ohm resistor, usually connected in series in the +24V dc power line at the power supply.

Note, the MSP400 requires a minimum voltage of 12V dc at the terminals for correct operation.
