3.1 Incoming acceptance, transport and storage

3.1.1 Incoming acceptance

On receipt of the goods, check the following:

• Check the packaging and the contents for damage.

• Check the shipment, make sure nothing is missing and that the scope of supply matches your

order.

3.1.2 Transport

The following instructions apply to unpacking and to transporting the device to its final location:

• Transport the devices in the containers in which they are delivered.

• Do not remove the protective plates or caps on the process connections until you are ready to

install the device. This is particularly important in the case of sensors with PTFE linings.

Special notes on flanged devices

Caution!

• The wooden covers mounted on the flanges from the factory protect the linings on the flanges

during storage and transportation. In case of Promag L they are additionally used to hold the lap joint flanges in place. Do not remove these covers until immediately before the device in the pipe.

• Do not lift flanged devices by the transmitter housing, or the connection housing in the case of

the remote version.

Transporting flanged devices DN  300 (12")

Use webbing slings slung round the two process connections. Do not use chains, as they could damage the housing.

Warning! Risk of injury if the measuring device slips. The center of gravity of the assembled measuring device might be higher than the points around which the slings are slung. At all times, therefore, make sure that the device does not unexpectedly turn around its axis or slip.

Installation Promag 50

Transporting flangeddevices DN > 300 (> 12")

Use only the metal eyes on the flanges for transporting the device, lifting it and positioning the sensor in the piping.

Caution!

Do not attempt to lift the sensor with the tines of a fork-lift truck beneath the metal casing. This would buckle the casing and damage the internal magnetic coils.

a0004295

Fig. 5: Transporting sensors with DN > 300 (> 12")

3.1.3 Storage

Please note the following:

• Pack the measuring device in such a way as to protect it reliably against impact for storage (and transportation). The original packaging provides optimum protection.

• The storage temperature corresponds to the operating temperature range of the measuring transmitter and the appropriate measuring sensors  ä 99.

• Do not remove the protective plates or caps on the process connections until you are ready to install the device. This is particularly important in the case of sensors with PTFE linings.

• The measuring device must be protected against direct sunlight during storage in order to avoid unacceptably high surface temperatures.

• Choose a storage location where moisture does not collect in the measuring device. This will help prevent fungus and bacteria infestation which can damage the liner.

3.2 Installation conditions

3.2.1 Dimensions

The dimensions and installation lengths of the sensor and transmitter can be found in the "Technical Information" for the device in question. This document can be downloaded as a PDF file from www.endress.com. A list of the "Technical Information" documents available is provided in the "Documentation" section on  ä 116.

3.2.2 Mounting location

Entrained air or gas bubble formation in the measuring tube can result in an increase in measuring errors. Avoid the following locations:

• Highest point of a pipeline. Risk of air accumulating!

• Directly upstream from a free pipe outlet in a vertical pipeline.

A0008154

Fig. 6: Mounting location

Installation of pumps

Do not install the sensor on the intake side of a pump. This precaution is to avoid low pressure and the consequent risk of damage to the lining of the measuring tube. Information on the lining's resistance to partial vacuum can be found on  ä 103.

It might be necessary to install pulse dampers in systems incorporating reciprocating, diaphragm or peristaltic pumps. Information on the measuring system's resistance to vibration and shock can be found on  ä 99.

Partially filled pipes

Partially filled pipes with gradients necessitate a drain-type configuration. The Empty Pipe Detection function (EPD  ä 73) offers additional protection by detecting empty or partially filled pipes.

Caution!

Risk of solids accumulating. Do not install the sensor at the lowest point in the drain. It is advisable to install a cleaning valve.

A0008155

Fig. 8: Installation in a partially filled pipe

Down pipes

Install a siphon or a vent valve downstream of the sensor in down pipes whose length h  5 m (16.4 ft). This precaution is to avoid low pressure and the consequent risk of damage to the lining of the measuring tube. This measure also prevents the system losing prime, which could cause air pockets. Information on the lining's resistance to partial vacuum can be found on  ä 103.

3.2.3 Orientation

An optimum orientation position helps avoid gas and air accumulations and deposits in the measuring tube. However, Promag offers the additional Empty Pipe Detection (EPD) function to ensure the detection of partially filled measuring tubes, e.g. in the case of degassing fluids or varying process pressure:

• Electrode Cleaning Circuit (ECC) for applications with accretive fluids, e.g. electrically conductive deposits ( "Description of Device Functions" manual).

• Empty Pipe Detection (EPD) ensures the detection of partially filled measuring tubes, e.g. in the case of degassing fluids ( ä 73)

• Exchangeable Measuring Electrodes for abrasive fluids ( ä 92)

Vertical orientation

This is the ideal orientation for self-emptying piping systems and for use in conjunction with Empty Pipe Detection.

Fig. 10: Vertical orientation

Horizontal orientation

The measuring electrode plane should be horizontal. This prevents brief insulation of the two measuring electrodes by entrained air bubbles.

Caution!

Empty Pipe Detection functions correctly only when the measuring device is installed horizontally and the transmitter housing is facing upward ( å 10). Otherwise there is no guarantee that Empty Pipe Detection will respond if the measuring tube is only partially filled or empty.

3.2.5 Foundations, supports

If the nominal diameter is DN  350, mount the sensor on a foundation of adequate load-bearing strength.

Caution!

Risk of damage. Do not support the weight of the sensor on the metal casing: the casing would buckle and damage the internal magnetic coils.

3.2.6 Adapters

Suitable adapters to DIN EN 545 (double-flange reducers) can be used to install the sensor in largerdiameter pipes. The resultant increase in the rate of flow improves measuring accuracy with very slow-moving fluids. The nomogram shown here can be used to calculate the pressure loss caused by reducers and expanders.

Note! The nomogram only applies to liquids of viscosity similar to water.

1. Calculate the ratio of the diameters d/D.

2. From the nomogram read off the pressure loss as a function of flow velocity (downstream from

the reduction) and the d/D ratio.

3.2.7 Nominal diameter and flow rate

The diameter of the pipe and the flow rate determine the nominal diameter of the sensor. The optimum velocity of flow is between 2 and 3 m/s (6.5 to 9.8 ft/s)

The velocity of flow (v), moreover, has to be matched to the physical properties of the fluid:

• v < 2 m/s (v < 6.5 ft/s): for abrasive fluids

• v > 2 m/s (v > 6.5 ft/s): for fluids producing buildup

Note! Flow velocity can be increased, if necessary, by reducing the nominal diameter of the sensor ( ä 17).

3.2.8 Length of connecting cable

In order to ensure measuring accuracy, comply with the following instructions when installing the remote version:

• Fix cable run or lay in armored conduit. Cable movements can falsify the measuring signal especially in the case of low fluid conductivities.

• Route the cable well clear of electrical machines and switching elements.

• Ensure potential equalization between sensor and transmitter, if necessary.

• The permitted connecting cable length L

is determined by the fluid conductivity ( å 16).

max

A minimum conductivity of 20 μS/cm is required for measuring demineralized water. Most liquids can be measured as of a minimum conductivity of 5 μS/cm.

• The maximum connecting cable length is 10 m (32.8 ft) when empty pipe detection (EPD  ä 73) is switched on.

Seals

Comply with the following instructions when installing seals:

• Hard rubber lining  additional seals are always necessary.

• Polyurethane lining  no seals are required.

• For DIN flanges, use only seals according to EN 1514-1.

• Make sure that the seals do not protrude into the piping cross-section.

Caution! Risk of short circuit! Do not use electrically conductive sealing compounds such as graphite! An electrically conductive layer could form on the inside of the measuring tube and short-circuit the measuring signal.

Ground cable

• If necessary, special ground cables for potential equalization can be ordered as an accessory ( ä 76).

• Information on potential equalization and detailed mounting instructions for the use of ground cables can be found on  ä 55

Screw tightening torques (Promag W)

Please note the following:

• The tightening torques listed below are for lubricated threads only.

• Always tighten the screws uniformly and in diagonally opposite sequence.

• Overtightening the screws will deform the sealing faces or damage the seals.

• The tightening torques listed below apply only to pipes not subjected to tensile stress.

3.3.4 Installing the Promag P sensor

Caution!

• The protective covers mounted on the two sensor flanges guard the PTFE, which is turned over the flanges. Consequently, do not remove these covers until immediately before the sensor is installed in the pipe.

• The covers must remain in place while the device is in storage.

• Make sure that the lining is not damaged or removed from the flanges.

Note! Bolts, nuts, seals, etc. are not included in the scope of supply and must be supplied by the customer.

The sensor is designed for installation between the two piping flanges.

• Observe in any case the necessary screw tightening torques on  ä 33

• If grounding disks are used, follow the mounting instructions which will be enclosed with the shipment

Fig. 20: Installing the Promag P sensor

Seals

Comply with the following instructions when installing seals:

• PFA or PTFE lining  No seals are required!

• For DIN flanges, use only seals according to EN 1514-1.

• Make sure that the seals do not protrude into the piping cross-section.

Caution!

Ground cable

• If necessary, special ground cables for potential equalization can be ordered as an accessory ( ä 76).

• Information on potential equalization and detailed mounting instructions for the use of ground cables can be found on  ä 53

Installing the high-temperature version (with PFA lining)

The high-temperature version has a housing support for the thermal separation of sensor and transmitter. The high-temperature version is always used for applications in which high ambient temperatures are encountered in conjunction with high fluid temperatures. The high-temperature version is obligatory if the fluid temperature exceeds +150 °C.

Note! You will find information on permissible temperature ranges on  ä 100

Insulation

Pipes generally have to be insulated if they carry very hot fluids, in order to avoid energy losses and to prevent accidental contact with pipes at temperatures that could cause injury. Guidelines regulating the insulation of pipes have to be taken into account.

Caution!

Risk of measuring electronics overheating. The housing support dissipates heat and its entire surface area must remain uncovered. Make sure that the sensor insulation does not extend past the top of the two sensor shells.

3.3.5 Installing the Promag H sensor

The sensor is supplied to order, with or without pre-installed process connections. Pre-installed process connections are secured to the sensor with 4 or 6 hex-head threaded fasteners.

Caution!

The sensor might require support or additional attachments, depending on the application and the length of the piping run. When plastic process connections are used, the sensor must be additionally supported mechanically. A wall-mounting kit can be ordered separately from Endress+Hauser as an accessory ( ä 76).

Seals

When installing the process connections, make sure that the seals are clean and correctly centered.

36 Endress+Hauser

Page 37

Promag 50 Installation

Caution!

• With metal process connections, you must fully tighten the screws. The process connection forms a metallic connection with the sensor, which ensures a defined compression of the seal.

• With plastic process connections, note the max. torques for lubricated threads (7 Nm / 5.2 lbf ft). With plastic flanges, always use seals between connection and counter flange.

• The seals must be replaced periodically, depending on the application, particularly in the case of gasket seals (aseptic version)! The period between changes depends on the frequency of cleaning cycles, the cleaning temperature and the fluid temperature. Replacement seals can be ordered as accessories  ä 76.

Usage and assembly of ground rings (DN 2 to 25, 1/12" to 1")

In case the process connections are made of plastic (e.g. flanges or adhesive fittings), the potential between the sensor and the fluid must be equalized using additional ground rings. If the ground rings are not installed this can affect the accuracy of the measurements or cause the destruction of the sensor through the electrochemical erosion of the electrodes.

Caution!

• Depending on the option ordered, plastic disks may be installed at the process connections instead of ground rings. These plastic disks serve only as spacers and have no potential equalization function. In addition, they provide a sealing function at the interface between the sensor and process connection. For this reason, with process connections without ground rings, these plastic disks/seals must not be removed, or must always be installed.

• Ground rings can be ordered separately from Endress+Hauser as accessories ( ä 76). When placing the order, make certain that the ground ring is compatible with the material used for the electrodes. Otherwise, there is a risk that the electrodes may be destroyed by electrochemical corrosion! Information about the materials can be found on  ä 111.

• Ground rings, including the seals, are mounted within the process connections. Therefore, the fitting length is not affected.

1. Loosen the four or six hexagonal headed bolts (1) and remove the process connection from the

sensor (4).

2. Remove the plastic disk (3), including the two O-ring seals (2).

3. Place one seal (2) in the groove of the process connection.

4. Place the metal ground ring (3) on the process connection.

5. Now place the second seal (2) in the groove of the ground ring.

6. Finally, mount the process connection on the sensor again.

With plastic process connections, note the max. torques for lubricated threads (7 Nm / 5.2 lbf ft).

Welding the transmitter into the piping (weld nipples)

Caution! Risk of destroying the measuring electronics. Make sure that the welding machine is not grounded via the sensor or the transmitter.

1. Tack-weld the sensor into the pipe. A suitable welding jig can be ordered separately as an accessory ( ä 76).

2. Loosen the screws on the process connection flange and remove the sensor, complete with the seal, from the pipe.

3. Weld the process connection to the pipe.

4. Reinstall the sensor in the pipe. Make sure that everything is clean and that the seal is correctly seated.

Note!

• If thin-walled foodstuffs pipes are not welded correctly, the heat could damage the installed seal.

It is therefore advisable to remove the sensor and the seal prior to welding.

• The pipe has to be spread approximately 8 mm to permit disassembly.

Cleaning with pigs

If pigs are used for cleaning, it is essential to take the inside diameters of the measuring tube and process connection into account. All the dimensions and lengths of the sensor and transmitter are provided in the separate documentation "Technical Documentation"  ä 116.

4.4 Degree of protection

The devices meet all the requirements of IP 67 degree of protection. Compliance with the following points is mandatory following installation in the field or servicing in

order to ensure that IP 67 protection is maintained:

• The housing seals must be clean and undamaged when inserted into their grooves. The seals must be dried, cleaned or replaced if necessary.

• All threaded fasteners and screw covers must be firmly tightened.

• The cables used for connection must be of the specified outside diameter  ä 49.

• Firmly tighten the cable entries.

• The cables must loop down before they enter the cable entries ("water trap"). This arrangement prevents moisture penetrating the entry. Always install the measuring device in such a way that the cable entries do not point up.

• Remove all unused cable entries and insert plugs instead.

• Do not remove the grommet from the cable entry.

Fig. 46: Installation instructions, cable entries

Caution!

Do not loosen the threaded fasteners of the sensor housing, as otherwise the degree of protection guaranteed by Endress+Hauser no longer applies.

Note! The Promag L, Promag W and Promag P sensors can be supplied with IP 68 rating (permanent immersion in water to a depth of 3 meters (10 ft)). In this case the transmitter must be installed remote from the sensor. The Promag L sensors with IP 68 rating are only available with stainless steel flanges.

5.2 Brief operating instructions on the function matrix

Note!

• See the general notes on  ä 60.

• Detailed description of all the functions "Description of Device Functions" manual The function matrix comprises two levels, namely the function groups and the functions of the

function groups. The groups are the highest-level grouping of the control options for the device. A number of functions is assigned to each group. You select a group in order to access the individual functions for operating and configuring the device.

1. HOME position  F  Enter the function matrix

2. Select a function group (e.g. OPERATION)

3. Select a function (e.g. LANGUAGE) Change parameter/enter numerical values:

P  select or enter enable code, parameters, numerical values F  save your entries

Operation Promag 50

5.2.1 General notes

The Quick Setup menu ( ä 70) is adequate for commissioning in most instances. Complex measuring operations on the other hand necessitate additional functions that you can configure as necessary and customize to suit your process parameters. The function matrix, therefore, comprises a multiplicity of additional functions which, for the sake of clarity, are arranged in a number of function groups.

Comply with the following instructions when configuring functions:

• You select functions as described on  ä 59.

• You can switch off certain functions (OFF). If you do so, related functions in other function groups will no longer be displayed.

• Certain functions prompt you to confirm your data entries. Press P to select "SURE [ YES ]" and press F again to confirm. This saves your setting or starts a function, as applicable.

• Return to the HOME position is automatic if no key is pressed for 5 minutes.

Note!

• The transmitter continues to measure while data entry is in progress, i.e. the current measured values are output via the signal outputs in the normal way.

• If the power supply fails, all preset and configured values remain safely stored in the EEPROM.

Caution! All functions are described in detail, including the function matrix itself, in the "Description of Device Functions" manual, which is a separate part of these Operating Instructions.

5.2.2 Enabling the programming mode

The function matrix can be disabled. Disabling the function matrix rules out the possibility of inadvertent changes to device functions, numerical values or factory settings. A numerical code (factory setting = 50) has to be entered before settings can be changed. If you use a code number of your choice, you exclude the possibility of unauthorized persons accessing data ( see the "Description of Device Functions" manual).

Comply with the following instructions when entering codes:

• If programming is disabled and the P operating elements are pressed in any function, a prompt for the code automatically appears on the display.

• If "0" is specified as the customer's code, programming is always enabled.

• The Endress+Hauser service organization can be of assistance if you mislay your personal code.

Caution! Changing certain parameters such as all sensor characteristics, for example, influences numerous functions of the entire measuring system, particularly measuring accuracy. There is no need to change these parameters under normal circumstances and consequently, they are protected by a special code known only to the Endress+Hauser service organization. Please contact Endress+Hauser if you have any questions.

5.2.3 Disabling the programming mode

Programming is disabled if you do not press the operating elements within 60 seconds following automatic return to the HOME position. You can also disable programming in the "ACCESS CODE" function by entering any number (other than the customer's code).

5.3 Displaying error messages

5.3.1 Type of error

Errors which occur during commissioning or measuring operation are displayed immediately. If two or more system or process errors occur, the error with the highest priority is the one shown on the display.

The measuring system distinguishes between two types of error:

• System errors  ä 80: This group comprises all device errors, e.g. communication errors, hardware faults, etc.

• Process errors  ä 82: This group comprises all application errors, e.g. empty pipe, etc.

A0000991

Fig. 49: Error messages on the display (example)

1 Error type:

– P = process error – S = system error

2 Error message type:

– $ = fault message

– ! = notice message 3 Error designation: e.g. EMPTY PIPE = measuring tube is only partly filled or completely empty 4 Error number: e.g. #401 5 Duration of most recent error occurrence (in hours, minutes and seconds)

5.3.2 Error message types

Users have the option of weighting certain errors differently, in other words having them classed as "Fault messages" or "Notice messages". You can define messages in this way with the aid of the function matrix ( "Description of Device Functions" manual). Serious system errors, e.g. module defects, are always identified and classed as "fault messages" by the measuring device.

Notice message (!)

• Displayed as  Exclamation mark (!), error type (S: system error, P: process error)

• The error in question has no effect on the outputs of the measuring device.

Fault message ($)

• Displayed as  Lightning flash ( $), error type (S: system error, P: process error).

• The error in question has a direct effect on the outputs.

The response of the individual outputs (failsafe mode) can be defined in the function matrix using the "FAILSAFE MODE" function ( "Description of Device Functions" manual).

Note! For security reasons, error messages should be output via the status output.

5.4 Communication

In addition to local operation, the measuring device can be configured and measured values can be obtained by means of the HART protocol. Digital communication takes place using the 4–20 mA current output HART  ä 52.

The HART protocol allows the transfer of measuring and device data between the HART master and the field devices for configuration and diagnostics purposes. The HART master, e.g. a handheld terminal or PC-based operating programs (such as FieldCare), require device description (DD) files which are used to access all the information in a HART device. Information is exclusively transferred using so-called "commands". There are three different command classes:

• Universal commands: All HART device support and use universal commands. The following functionalities are linked to them: – Identify HART devices – Reading digital measured values (volume flow, totalizer, etc.)

• Common practice commands: Common practice commands offer functions which are supported and can be executed by most but not all field devices.

• Device-specific commands: These commands allow access to device-specific functions which are not HART standard. Such commands access individual field device information, amongst other things, such as empty/full pipe calibration values, low flow cutoff settings, etc.

Note! The device has access to all three command classes. A list of all the "Universal commands" and "Common practice commands" is provided on  ä 64.

5.4.1 Operating options

For the complete operation of the measuring device, including device-specific commands, there are DD files available to the user to provide the following operating aids and programs:

Field Xpert HART Communicator

Selecting device functions with a HART Communicator is a process involving a number of menu levels and a special HART function matrix. The HART manual in the carrying case of the HART Communicator contains more detailed information on the device.

Operating program "FieldCare"

FieldCare is Endress+Hauser’s FDT-based plant Asset Management Tool and allows the configuration and diagnosis of intelligent field devices. By using status information, you also have a simple but effective tool for monitoring devices. The Proline flow measuring devices are accessed via a service interface or via the service interface FXA193.

In the case of measuring devices without a local display, the individual parameters and functions must be configured via the operating program, e.g. FieldCare. If the measuring device is equipped with a local display, all the important device parameters for standard operation, as well as additional functions, can be configured quickly and easily by means of the following Quick Setup menu.

6.3.1 "Commissioning" Quick Setup menu

This Quick Setup menu guides you systematically through the setup procedure for all the major device functions that have to be configured for standard measuring operation.

6.4.1 Current output: active/passive

The current output is configured as "active" or "passive" by means of various jumpers on the I/O board.

Warning! Risk of electric shock! Exposed components carry dangerous voltages. Make sure that the power supply is switched off before you remove the cover of the electronics compartment.

1. Switch off power supply.

2. Remove the I/O board  ä 87

3. Position the jumper  å 51

Caution!

Risk of destroying the measuring device. Set the jumpers exactly as shown in the graphic. Pay strict attention to the position of the jumpers as indicated in the graphic.

6.5 Adjustment

6.5.1 Empty-pipe/full-pipe adjustment

Flow cannot be measured correctly unless the measuring tube is completely full. This status can be permanently monitored using the Empty Pipe Detection:

• EPD = Empty Pipe Detection (with the help of an EPD electrode)

• OED = Open Electrode Detection (Empty Pipe Detection with the help of the measuring electrodes, if the sensor is not equipped with an EPD electrode or the orientation is not suitable for using EPD).

Caution!

Detailed information on the empty-pipe/full-pipe adjustment procedure can be found in the "Description of Device Functions" manual:

• EPD/OED ADJUSTMENT (carrying out the adjustment).

• EPD (switching on and off EPD/OED).

• EPD RESPONSE TIME (input of the response time for EPD/OED).

Note!

• The EPD function is not available unless the sensor is fitted with an EPD electrode.

• The devices are already calibrated at the factory with water (approx. 500 μS/cm). If the fluid conductivity differs from this reference, empty-pipe/full-pipe adjustment has to be performed again on site.

• The default setting for EPD when the devices are delivered is OFF; the function has to be activated if required.

• The EPD process error can be output by means of the configurable relay output.

Performing empty-pipe and full-pipe adjustment (EPD)

1. Select the appropriate function in the function matrix:

HOME  F  R PROCESS PARAMETER  F  R EPD ADJUSTMENT

2. Empty the piping:

– The wall of the measuring tube should still be wet with fluid during EPD empty pipe

adjustment

– The wall of the measuring tube/the measuring electrodes should no longer be wet with

fluid during OED empty pipe adjustment

3. Start empty-pipe adjustment: Select "EMPTY PIPE ADJUST" or "OED EMPTY ADJUST" and

F to confirm.

press

4. After empty-pipe adjustment, fill the piping with fluid.

5. Start full-pipe adjustment: Select "FULL PIPE ADJUST" or "OED FULL ADJUST" and press F

to confirm.

6. Having completed the adjustment, select the setting "OFF" and exit the function by pressing F.

7. Switch on empty pipe detection in the EPD function:

– EPD empty pipe adjustment: Select ON STANDARD or ON SPECIAL and press F to confirm – OED empty pipe adjustment: Select OED and confirm with F.

Caution!

The adjustment coefficients must be valid before you can activate the EPD function. If adjustment is incorrect the following messages might appear on the display: – FULL = EMPTY

The adjustment values for empty pipe and full pipe are identical. In cases of this nature you must repeat empty-pipe or full-pipe adjustment!

– ADJUSTMENT NOT OK

Adjustment is not possible because the fluid’s conductivity is out of range.

9.7 Return

Caution!

Do not return a measuring device if you are not absolutely certain that all traces of hazardous substances have been removed, e.g. substances which have penetrated crevices or diffused through plastic. Costs incurred for waste disposal and injury (burns, etc.) due to inadequate cleaning will be charged to the owner-operator.

The following steps must be taken before returning a flow measuring device to Endress+Hauser, e.g. for repair or calibration:

• Always enclose a duly completed "Declaration of contamination" form. Only then can Endress+Hauser transport, examine and repair a returned device.

• Enclose special handling instructions if necessary, for example a safety data sheet as per EC REACH Regulation No. 1907/2006.

• Remove all residues. Pay special attention to the grooves for seals and crevices which could contain residues. This is particularly important if the substance is hazardous to health, e.g. flammable, toxic, caustic, carcinogenic, etc.

Note! You will find a preprinted "Declaration of contamination" form at the back of these Operating Instructions.
