<1. INTRODUCTION>

1.4 General description

This manual describes installation, operation and maintenance of the RAMC. Please read it carefully before using this device. Further, please note that customer features are not described in this manual. When modifying specications, construction or parts, this manual is not necessarily revised unless it can be assumed that these changes will impair RAMC functions or performance. All units are thoroughly tested before shipping. Please check the received units visually to ensure that they have not been damaged during transport. In case of defects or questions please contact your nearest YOKOGAWA service centre or sales office. Please describe any defect precisely and indicate model code as well as serial number. YOKOGAWA refuses any liability for units which have been repaired by the user without prior consent and do not meet the specications as a consequence.

1.5 Principle of measurement

The RAMC is a Variable Area Flow Meter for volume and mass measurements of gases and liquids. A oat, whose movement is nearly independent of viscosity is guided concentrically in a specially shaped cone. The position of the oat is transferred magnetically to the indicator, which shows the measurement values by a pointer on a scale. The indicator can be equipped with limit switches and an electronic transmitter.

Fig. 1-1

All units are calibrated with water by the manufacturer. By adjusting the calibration values to the measured substance’s state of aggregation (density, viscosity), the ow rate scale for each measuring tube can be determined. Indication units can be exchanged without impairment of precision. However, the scale for the tube must be mounted on the new indicator (and in case of an electronic transmitter the calibration EEPROM, too).

<2. PRECAUTIONS>

2. Precautions

2.1 Transportation and storage

Before transporting the unit, it is recommended to x the oat with a card-board strip in the same way as when shipped from factory. Prevent foreign objects from entering the tube (e.g. by covering openings). To protect the unit and especially the tube’s interior from soiling, store it only at clean and dry locations

2.2 Installation

Ambient temperature and humidity of the installation location must not exceed the specied ranges. Avoid locations in corrosive environments. If such environments are unavoidable, ensure sufficient ventilation. Although the RAMC features a very solid construction, the instrument should not be exposed to strong vibration or impact stress. Please note that the RAMC’s magnetic sensing system can be inuenced by external inhomogeneous magnetic elds (such as solenoid valves). Alternating magnetic elds (≥ 10 Hz) as well as homogeneous, static magnetic elds (in the area of the RAMC), like the geomagnetic eld have no inuence. Asymmetric ferromagnetic bodies of considerable mass (e.g. steel girders) should be kept at a distance of at least 250 mm from the RAMC. To avoid interference, the distance between two adjacent RAMC must be at least 300 mm.

2-1

2.3 Pipe connections

Ensure that the bolts of the anges are tightened properly and that the gaskets are tight. Do not expose the unit to pressures higher than the indicated maximum operating pressure (refer to specications). While the system is pressurized the ange bolts must not be tightened or loosened.

3. Installation

3.1 Installation in the pipeline

Be sure to remove the transport lock card-board strip from the measuring tube. Check that no cardboard remains in the tube. The RAMC ow rate meter must be installed in a vertical pipeline, in which the medium ows upwards. vertical position has to be checked at the outer edge of the anges. Bigger nominal diameters (DN80/DN100) require straight pipe sections of at least 5D in front and behind the RAMC. The nominal diameter of the RAMC should correspond to the nominal diameter of the pipeline. To avoid stress in the connecting pipes, the connecting anges must be aligned in parallel and axial direction. Bolts and gaskets have to be selected according to the maximum operating pressure, the temperature range and corrosion conditions. Center gaskets and tighten nuts with a torque appropriate for the pressure range. If contamination or soiling of the RAMC is to be expected, a bypass should be installed to allow the removal of the instrument without interruption of the ow. Please read also chapter 2.2. For further instructions on installation please refer to VDI/VDE3513.

3.2 Wiring of electronic transmitter (-E, -H, -J) and limit switches (/K

Please regard the drawings on the following pages.

On the rear of the RAMC are two cable glands for round cables with a diameter of 6 to 9 mm (not for Ex-d-type option /F1). Unused glands must be closed with a blind plug M16x1.5. For wiring of RAMC with option/F1 see chapter 10.10.2, 10.11.2, 10.14.2. Wires should not be bent directly at terminal screws. Do not expose wires to mechanical pressure. Wires must be arranged according to common installation rules, especially signal and power lines must not be bundled together. Cables should not be bend directly after the cable gland. Do not x cable at the measuring tube. The RAMC terminals accept wires with a maximum sectional area of 1.5 mm2.

The attached ferrite core must be mounted on the cable as shown on the below picture. Distance "L" < 2 cm.



)

L

Measuring and indicating instruments, connected in series to the output of the electronic transmitter, must not exceed a load impedance of R 2- or 3-wire units are connected to the terminals marked “+”, “-” and “A” of the power connector. For 2-wire instruments the terminals “-” and “A” have to be shorted with a jumper. Take care not to loose that jumper when mounting wires. Wiring inside the case should be kept as short as possible to avoid that moving parts are blocked.

Attention: Hints for Unit Safety (according DIN EN 61010-1)

- Do not connect cables outdoors in wet weather in order to prevent damage from condensation and to protect the insulation, e.g. inside the terminal box of the owmeter.

- Heed the nominal voltage indicated on the scale.

- Use the cables which fulll specication and check before wiring.

- The electrical connections have to be executed according to VDE0100 “Errichten von Starkstromanlagen mit Nennspannungen bis 1000 V” (Installation of high current assemblies with nominal voltages of up to 1000 V)

or equivalent national regulations.

- For units with a nominal voltage of 115 V or 230 V the correspondingly marked terminal has to be

connected to protective earth (PE).

- Units with a nominal voltage of 24 V may only be connected to a protected low voltage circuit (SELV-E

according to VDE0100/VDE 0106 or IEC 364/IEC 536).

- The RAMC indicator housing must be grounded to ensure electromagnetic interference protection.

This can be done by grounding the pipeline.

- Once all wiring is complete, check the connections before applying power to the instrument. Improper

arrangements or wiring may cause a unit malfunction or damage.

- This unit does not include a power switch. Therefore, a switch has to be prepared at the installation

location in the vicinity of the unit. The switch should be marked as the power separation switch for the RAMC.

<4. START OF OPERATION>

4-1

4. Start of operation

4.1 Hints on ow rate measurement

The measured uid should neither consist of a multi-phase mixture nor contain ferrite ingredients or large solid mass particles. The RAMC scale is adjusted to the state of operation/aggregation of the measured uid by the manufacturer. If the state of operation changes, it might become necessary to establish a new scale. This depends on several factors:

- If the RAMC is operated in the given viscosity independent range, only the density of the oat as well as the operational density of the previous and new substance have to be considered. In case the operational density only changes marginally (≤ 0.5 %), the present scale can be used.

- If the RAMC is operated outside the given viscosity independent range, the viscosities at the previous and new state of operation as well as the mass and diameter of the oat have to be taken into account.

4.2 Pulsation and pressure shock

Pressure shock waves and pulsating ow inuence measurement signicantly or can destroy the meter. Surge conditions should be avoided. (open valves slowly, raise operating pressure slowly) If oat bouncing occurs in gases increase the line pressure until the phenomena stops. If this is not possible provide the oat with a damper. A damping kit is available as spare part.

4.3 Start of operation of electronic transmitter

Ensure that the device has been connected correctly according to section 3-2 and that the used power supply meets the requirements indicated on the scale. Switch on the power supply. The digital display gives the totalizer value in the measuring unit, indicated on the right side of the display. The RAMC is now ready for operation. Unit graduation, measuring unit, damping, etc. can be adjusted by an operating menu (refer to section 6.2). In case of an error, the bars beneath the 8 digits of the display will ash. The corresponding error message can be checked using the operating menu and then taking the appropriate counter measures (refer to section 6-2-8 “Error Messages”). The transmitter has been prepared and calibrated according to the model code as a 2-, 3- or 4-wire unit. In 2-wire units, a jumper connects “A” and “-”. When switching from a 2- to a 3-wire conguration, this jumper should be removed. The current output should then be adjusted as explained in section 6-2-6. When changing from a 3- to 2-wire conguration, the jumper should be set in place, and the current output has to be adjusted according to section 6-2-6.

5. Limit switches (Option /K)

The optional limit switches are available as maximum or minimum type switches. They are proximity switches according to EN 60947-5-6 (NAMUR). Maximum two switches can be installed. The option (/W) includes the respective transmitter relay. These switches have been specied for hazardous area. However, the transmitter relay must be installed in safe area. The limit switches are connected to the transmitter relays as indicated in chapter 3.2. The terminals for the limit switches are on a small board on top of the transmitter case.

Use of 2 standard limit switches (option /K3):

The MIN-MIN and MAX-MAX functions have been integrated at the factory as MIN-MAX switches in the RAMC. The MIN-MIN or MAX-MAX function is set by adjusting the switching direction of the transmitter relay. The concerning 2- channel transmitter relays are: Option /W1B: KFA5-SR2-Ex2.W Option /W2B: KFA6-SR2-Ex2.W Option /W4B: KFD2-SR2-Ex2.W The following table shows the assignment:

Function Switching direction of transmitter relay *

Channel 1 Channel 2 Channel 1 Channel 2

MIN MAX S1 position I S2 position I MIN MIN S1 position I S2 position II (ON)

MAX MAX S1 position II (ON) S2 position I

* see following gure for S1 and S2 on transmitter relay.

Use of Fail Safe limit switches (option /K6.../K10):

For Fail Safe application only 1- channel transmitter relays are available.

Option /W2E: KHA6-SH-Ex1.W Option /W2F: 2 x KHA6-SH-Ex1.W Option /W4E: KFD2-SH-Ex1.W Option /W4F: 2 x KFD2-SH-Ex1.W

If other transmitter relays are used as the above mentioned types, the transmitter relay has to be applied as protection technology to ensure functional safety.

Please notice chapter 9.3 "Standard specications".

6. Electronic Transmitter (-E)

6.1 Operation principle

The position of the oat is magnetically transferred to a magnetic follow up system. The position angle of this magnetic rocker is detected by magnet sensors. A micro controller determines the angle by means of a combining reference value table in the memory and calculates the ow rate by the angle with calibration and operation parameters the calibration EEPROM. The ow rate is given as a current, either 0-20 mA or 4-20 mA, and, in addition, indicated on the digital display (refer also to section 6-2). The electronic transmitters have been electronically adjusted before shipping and, therefore, are mutually exchangeable. Calibration data of the metering tube as well as customer specic data are entered into a calibration EEPROM, inserted on the board. This calibration EEPROM and the indication scale are assigned to the respective metering tube. When replacing an indicator (e.g. because of a defect) the scale and calibration EEPROM of the old unit have to be inserted in the new unit. Then, no calibrations or adjustments are necessary. If an indicator with electronic transmitters is installed to a new metering tube, the calibration EEPROM of that tube has to be inserted into the transmitter and the indicator scale for that particular tube has to be mounted.

A change in the uid data (e.g. specic gravity, pressure, etc.) requires the preparation and mounting of a new calibration EEPROM and scale.

Normally the range of the current output is equal to the rounded measuring range of the tube (end value on scale). The customer can position the 20 mA point between 60% and 100% of the end value on scale. The set of the 20 mA point is shown on the scale (refer to Fig. 1-4). The ow cut off is positioned at 5 % of the end value. Below 5 % ow the current output shows 0 mA (4 mA).

6.2 Parameter setting

The displays allows indication of various parameters:

• Flow rate (8 mass or volume units in combination with 4 time units)

• Counter (8 mass or volume units)

• Flow rate indication in percent

• Special functions

• Setting of different damping times

• Switching of current output 0-20 mA / 4-20 mA or vice versa

• Indication of error messages

• Manual adjustment

• Service functions

• Detection of oat blockage

The setting of these parameters is done by two buttons.

- upper button ( ↑ ) : Exit setting mode

- lower button ( → ) : Scroll through menu/selection of parameters

- both buttons ( ↑ + → ) = Enter : Entering parameters/selecting setting mode If no button is pressed for one minute while the operating menu is active, the indication reverts to the measuring indication. This does not apply to subfunctions F32, F33, F52, F63. For indication of volume or mass values at maximum 6 digits in front of the decimal point and 7 decimals are used. This format allows an indication range for ow rates from 0.0000001 unit/time to 106000 unit/time. Flow rate values exceeding 106000 are shown as ‘————’ on the display. In this case the next bigger ow rate unit (next smaller time unit) has to be selected. For the indication of totalizers values 8 digits are used at maximum of which 7 digits can be assigned for decimal values. The decimal point setting is determined by selecting the unit. Therefore, possible totalizer offsets are: Unit *1 Unit *1/10 Unit *1/100 The totalizer counts up to 99999999 or 9999999.9 or 999999.99 and is reset to zero. The next page shows the operating menu.

An adjusting step corresponds to 20 µA. The complete adjusting range is ± 0.62 mA (31 steps). If the adjusting range does not suffice, change to display F32 or F33 by pressing ENTER when display shows F32 31 or F33 31, press ENTER again and continue adjusting at F32 00 or F33 00. 3 wire connection: At this the ranges 0-20 mA and 4-20 mA are possible. At a switch over between the two ranges with F31 the current output is automatically adjusted at equipment as of rmware version 1.4 . (s.F 61). A perhaps necessary ne adjustment can be carried out with F32 or F33. 2 wire connection: At this only the range of 4-20 mA is meaningful. The range of 0-20 mA is not closed however. At the change to 0-20 mA with F31 the equipment assumes a remodelling on 3 wire connection and the current output is adjusted according to this. A perhaps necessary ne adjustment can be carried out with F32 or F33.

Since YOKOGAWA doesn’t have any inuence on the custom-designed connection the current output is not automatically adapted, if the connection is changed from 2 wire to 3 wire or vice versa .This must be manually carried out with the functions F32 and F33.

6.2.7.1 General

The volume totalizer function in the electronic transmitter is available with a potential free pulse contact. The connection is supported only at 4-wire-units on the power supply at pins 6, 7. The pulse output is activated and selected by function F34 in the menu structure. Two different pulse rates can be selected. The lower pulse rate (higher solution) corresponds to the last (least signicant) digit of the totalizer. The higher pulse rate (lower solution) corresponds to the last but one digit of the totalizer.

6.2.7.2 Connection

6.2.7.3 Adjustments

The function F34 is added to the menu structure. With the selection of F34 -1 the pulse output is switched off. With the selection of the functions F34 -2 or F34 -3 the pulse output is activated with the concerning solution.

· F34 -1 not active

· F34 -2 last totalizer digit

· F34 -3 last but one totalizer digit

Special case: If Qmax is higher than 10000, the pulse rate is decreased by factor 10 in both cases. That means:

· F34 -2 last but one totalizer digit

· F34 -3 third totalizer digit from the right

6.2.7.4 Calculation of pulse rate

Concerning the nal ow-value (Qmax ), which was declared in the customers order, the pulse rate is calculated in factory and is written onto the sheet ´Data of Pulse Output (Option /CP)´, which is included. This value can be transferred to a blank label of the also included sheet with unit-stickers and then xed on the scale. After changing the ow rate unit with F12 the pulse rate must be recalculated. Calculation of pulse rate:

· Read the value of Qmax from the scale or recalculate it.

· Search for the concerning range in the rst row of the table below.

· Read the concerning pulse rates in the second and third row.

· The measuring unit is equal to the ow

• After changing the ow rate unit with F12 the pulse-register is deleted and the pulse rate is automatically

redened according to the new unit.

• After totalizer Reset with F14 the pulse output does not change.

• When changing the indication with F11 -3 to ´%´, the totalizer stops and the pulse output is switched off.

• After switching power on one pulse is generated at the output.

• For 2- respectively 3-wire-units the function F34 is not supported.

6.2.9 Manual adjustment (F5-)

During manufacturers adjustment and calibration process the relation between ow rate with water (or with air) and oat position (indicated as angle on the mm-scale) is determined. Based on the properties of the customers uid at expected operating conditions the ow scale and the corresponding EEPROM is then calculated. If the uid properties are changing (by change of the uid or by change of the process conditions) the scale as well as the EEPROM has to be adapted. Easiest and recommended way to do this is to order new scale and EEPROM for the new properties from manufacturer and to replace both. A second possibility is to readjust the meter by the user. This readjustment procedure will only adjust the current output and the display indication (but only in % of the new ow range), At least the readjustment by the user is possible by two different procedures:

1 Manual “dry” readjustment based on recalculated original scale:

The following steps have to be performed:

1.a ) Calculate the new of ow rate to mm (on scale) relation based on original manufacturers calibration certicate.

1.b ) Place the RAMC (with the measuring tube) horizontally on a table (Note: the distance to any ferro magnetic parts must be at least higher than 25 cm!).

1.c ) Go to menu function F51 and press ENTER to switch to manual adjustment mode. (Switching back to the original adjustment is possible by pressing ENTER again).

1.d ) Go to menu function F52 in order to start the manual adjustment.

1.e ) Move the oat to a position where the pointer is indicating on mm-scale the mm-value belonging to 5 % of the new ow rate (Note: these values have to be calculated in step a rst!)

1.f ) Press ENTER to adjust the rst 5 % point.

1.g ) Repeat steps 1.e) to 1.f) for the 15 %; 25 %; 35 %; 45 %; 55 %; 65 %; 75 %; 85 %; 95 % and 105 % points. (Note: The whole loop from 5 % to 105 % has to be adjusted in the requested order without interruption. It is not possible to skip or stop and restart the adjustment.)

1.h ) The adjustment has to be nished and stored by pressing “ ↑ “.

After storage the new adjustment is permanently available and can be switched “on” or “off” by function F51.

When manually adjustment is active, the user is responsible for the measurement accuracy.

2 Manual “wet” adjustment by comparison to a reference master meter with the real process uid at operating conditions:

This adjustment is useful under the following conditions:

• The original manufacturer’s calibration is not available or needs to be renewed. Or

• The user is not able to recalculate the new mm to ow rate table. And

• The user has the possibility to compare the meter indication with a master meter with the process uid at process conditions.

In these cases the following steps have to be performed:

2.a ) Place the RAMC in line with the master meter in an installation allowing controlled ow with the process uid at process conditions in a ow range from 5 % to 105 % of the expected ow range.

2.b ) Go to menu function F51 and press ENTER to switch to manual adjustment mode. (Switching back to the original adjustment is possible by pressing ENTER again).

2.c ) Go to menu function F52 in order to start the manual adjustment.

2.d ) Set the ow to 5 % of the new ow rate indicated by the master.

2.e ) Press ENTER to adjust the rst 5 % point.

2.f ) Repeat steps 2.d) to 2.e) for the 15 %; 25 %; 35 %; 45 %; 55 %; 65 %; 75 %; 85 %; 95 % and 105 % points. (Note: The whole loop from 5 % to 105 % has to be adjusted in the requested order without interruption. It is not possible to skip or stop and restart the adjustment.)

2.g ) The adjustment has to be nished and stored by pressing “ ↑ “.

After storage the new adjustment is permanently available and can be switched “on” or “off” by function F51.

IM 01R01B02-00E-E 14th edition January 20, 2017 -00

<6. ELECTRONIC TRANSMITTER (-E)>

For the manual adjustment procedure according to the two cases described the following remarks have to be taken into account:

• After manual adjustment the ow-scale of the indicator is no longer valid.

• The display will only indicate in % of the new ow range.

• Switching of units is impossible.

• The indicator can be always resetted to the original adjustment according to manufacturers calibration at any time.

• The given procedures will only adjust the current output and the display to the new measuring range for a different uid and/or new process conditions.

• The result of this adjustment is NOT a calibration! If proof of the new adjustment is requested a real calibration by comparison to a standard has to be made after adjustment!

• The following interactions with other functions apply:

Interaction with other functions:

Action Function Effect

1. Setting of manual adjustment values F52 -5... Manual adjustment table is overwritten

2. Activating of manual adjustment table F51 -2 - Manual adjustment table active

- %-indication only

- Totalizer does not count

- No other ow rate unit selectable

- Function F64 for option /A2 has no effect, with manual adjustment

3. Deactivating of manual adjustment table

F51 -1 - Standard adjustment table active

- F11 is set to ow rate

- Flow unit is the same as before activating manual adjustment

- Totalizer value is the same as before activating manual adjustment

Due to the limitations described it is strongly recommended to order a new scale and EEPROM from manufacturer (this gives a real new ow scale without new calibration) or to order a new calibration by the manufacturer together with a new scale and EEPROM for the new uid and/or new process conditions (this gives new adjustment plus new calibration).

6.2.14 Float blocking indication (F7-)

6.2.14.1 Function

Float

Pulsating movements of the ow medium (gasses, liquids) lead to uctuations of the oat and with that to uctuations of the tap system/pointer. Therefore the electrical measuring signal permanently changes and with that the display value and the output current value. The uctuations can be reduced with the help of the damping function “F21”. That shows however that the medium still ows and the oat/the tap system is not blocked. This means that in most applications there is a permanently changing measuring signal which can be used for the recognition of the movement or the blockade of the oat.

Basic noise

Since it is an electronic evaluation circuit, permanently minimal uctuations of the measuring signal appear. The basic noise is caused by vibrations in the plant as well as by temperature inuences or external magnetic elds. The basic noise also appears, if

- no medium ows through the measuring pipe

- the oat and with that the tap system are in the rest position

- the oat/the tap system is blocked.

Float-Blocking-Indication

The function of the Float-Blocking-Indication allows the electronic transmitter to distinguish the uctuations, which are caused by a moving oat, with the uctuations of the basic noise to state a fault status. If the measuring signal does not exceed the autozero value during a dened supervision time, this is recognized as blockade and an error condition is shown.

6.2.14.2 Operation

Switching on

At delivery of the equipment the Float-Blocking-Indication is turned off. By the function “F71 2” the FloatBlocking-Indication can be activated.

Autozero function

The autozero function is called to nd out the level of basic noise in the application. This is started with the function “F74 1” and lasts for 90 seconds. While the autozero function is running the value “0.000” is displayed and the 4 bars will ash below the numbers. After approx. 80 seconds the current autozero value appears on the display. This value gets stored and will not be lost after power off / on the RAMC or after switching off / on the Float-Move-Detection-function. The stored value is typed over rst after a renewed autozero.

Autozero without ow

To execute the autozero function the following expiry is recommended:

- Plant in operation (measuring tube lled with medium)

- Drive ow to zero (place oat into rest position)

- Raise the pointer to 10 % to 20 % of the ow and x it on the scale with adhesive tapes or underlayed paper stripe .

- Start Autozero function by menu.

- Check Autozero value after approx. 80 seconds.

During the Autozero function it absolutely has to be respected that:

- the RAMC is not moved by touching or using the 2 buttons.

- the pointer is protected against slipping.

- the tube is not exposed to strong tremors

If these prerequisites are not adhered, it comes to the inquiry of too high autozero results. This leads that a relatively quiet ow can trigger the Float-Blocking-Indication.

IM 01R01B02-00E-E 14th edition January 20, 2017 -00

<6. ELECTRONIC TRANSMITTER (-E)>

6-19

Autozero with ow

The Autozero function can be carried out also under ow, if the ow cannot be switched off. To this the following expiry is recommended:

- Plant in operation (measuring tube lled with medium)

- Move ow to constant value (preferably between 10 % and 40 %)

- Fix pointer on the oriented scale factor with adhesive tapes or underlayed paper stripe

- Start Autozero function by menu.

- Check Autozero value after approx. 80 seconds.

It has to be respected on this absolutely, for this the ow is constant during the Autozero duration! Normally at this variant higher Autozero results must be expected !

Autozero range

The factory default autozero value is zero (0.000). At the inquiry of the autozero value it has to be respected that the pointer / tap system are not in the rest position. In this case the autozero value is zero and the Float-Move-Detection does not work. Normally the autozero value is smaller than 0.200. If higher results should appear in the application, a multiple inquiry of the autozero value is recommended to conrm the value.

Supervision range (measuring range)

The measuring range in which Float-Move-Detection is active lies between 5 % and 105 % of the maximum ow Qmax (Factory Setting). With the help of the function “F72” this range can be reduced if a supervision is not possible or not desired in the lower ow range. The range can be restricted to 15 % or 30 % to 105 % (see point 3.1 to 3.3).

Supervision time (Time Out)

The supervision time of the measuring signal is 5 minutes (Factory Setting). If the measuring signal should not exceed the autozero value during this period, this is recognized as blockade and an error condition is shown. The supervision time can be increased with the function “F73” up to 15 minutes.

Indication of a blocking condition

After the recognition of the blockade the error code “08” is produced and the bars under the displayed measurement value are ashing (see fault behavior). Simultaneously the current output is set to a value, which enables a clear fault detection of a connected evaluation unit:

6.2.14.3 Unsuitable applications

It is possible, that the Float-Blocking-Indication - Function does not work satisfactory. This can be caused with different factors which are explained briey here. In these cases the function of the Float-Blocking-Indication is not suitable for the respective application and it should be turned off.

Applications with gases

At applications with gases and oat-damping it can happen, that the pulsating movements of the medium (and with that of the oat) are damped so strongly in the measuring tube, that the measuring signal lies under the autozero value and a Float-Blocking-Indication is not possible.

Applications with high viscous media

If a high viscous medium should be used in the plant, the damping can get so high by the high viscosity of the ow that the measuring signal lies below the autozero value, and a Float-Blocking-Indication is not possible.

Applications with quiet ow

If the plant has an extremely quiet ow (gases or liquids) ,the supervision range can be limited in the lower ow range. Normally greater ow (> 30 %) causes greater medium ow deviations. The duration of the supervision can be put to 15 minutes to reach a longer supervision time.

HART - Communication

7.1 General

RAMC with indication unit type -H or -J have, additional to the current output, the possibility for HARTCommunication. Also without HART- Communication the units are fully able to work. The HART-Communication does not inuence the current output, except in Multidrop-Mode (see below). There exists no difference between the not-Ex and the Ex versions. For use in the hazardous area a HART-able transmitter power supply is required.

The HART- Communication is only available with plugged calibration-EEPROM

The HART- Communication is only available for 2-wire units, 4...20mA. Therefore the short-circuit bridge must be connected between ´ A ´ and ´-´.

Deviations in the RAMC- Menu

In HART devices the operating menu according chapter 6 is not available.

HART 5: Pressing the ↑ -button the indication can be changed between ow, totalizer and temperature. HART 7: Pressing the ↑ -button the indication can be changed between ow, totalizer, percent and temperature. Factory default is totalizer. Pressing → button an error indication appears on display. 00000000 or 00000000

A detailed explanation see chapter 7.4.2 and 7.6.2.

7.1.1 Multidrop Mode in the case of using HART 5

“Multidropping” transmitters refer to the connection of several transmitters to a single communication transmission line. Up to 15 transmitters can be connected when set in the multidrop mode. To activate multidrop communication, the transmitter address must be changed to a number from 1 to 15. This change deactivates the 4 to 20 mA analog output, setting it to 4 mA. The alarm current is also disabled.

Setting of Multidrop Mode

Device Setup Detailed setup Device Information Poll addr Enter the number from 1 to 15(Def.: 0)

Enabling the Multidrop Mode

About the procedure to call up the Polling display, please refer to the User’s Manual of each conguration tool.

When the same Polling address is set for two or more transmitters in multidrop mode, communication with these transmitters is disabled.

Communication when set in multidrop mode

The HART conguration tool searches for a transmitter that is set in multidrop mode when it is turned on. When the HART conguration tool is connected to the transmitter, the polling address and the tag will be displayed.

Select the desired transmitter. After that, normal communication to the selected transmitter is possible. To release multidrop mode, call up the Poll addr display and set the address to “0”.

7.1.2 Multidrop Mode in the case of using HART 7

“Multidropping” transmitters refer to the connection of several transmitters to a single communication transmission line. Up to 63 transmitters can be connected when set in the multidrop mode. To activate multidrop communication, the transmitter address must be changed to a number from 1 to 63. This change does not deactivate the 4 to 20 mA analog output. The level at current output can be set by Lop current mode.

The minutes are added up, the period can be requested by the user any time. The actual maximum value is overwritten by a higher value automatically, if it lasts more than 30 seconds; the time measurement starts once more. The determined values (max temperature/period) can be cleared by the user. They are written into the parameter Old durat/value after Clear values or after power off/on, the actual time value is deleted, the max temperature value is set on the actual temperature value. By switching Temp max log off the values are not cleared. When exceeding the maximum temperature of 70 °C the error message “Temp over limit” appears.

Min overrun time Selection of hysteresis time Clear values Clears the values in URV overrun time and URV underrun time

Description of Flow URV logging function : The ow value is supervised constantly. As soon as the value reaches the upper limit value (103 %; 20.5 mA) (event 1), the time is measured, during the ow value is over the limit value. If this error condition remains actively longer than the hysteresis value, the limiting value recognition is activated and the condition stored. As soon as the ow value falls below the limit value, the supervision (event 2) ends, for a new cycle the hysteresis time must pass. After the recognition you can request the passed time: Time from event1 till query time: delta-T1 Time from event2 till query time: delta-T2 The time difference is the time the upper limit was exceeded. hysteresis <= t <= (delta-t1 - delta-t2) The stored values remain unchanged after power off and must be cleared by the user. The actual cycle is overwritten automatically by a new one. Therefore only the last cycle is always stored. The default value for hysteresis is 30 seconds.

Clear values The values in parameter Time/value are written to parameter Old time/value. Parameter Time/value is set to actual time stamp and temp max is set to actual temperature.

Description of temperature maximum logging function:

<7. HART-COMMUNICATION>

The temperature value is supervised constantly. As soon as the value exceeds the actual maximum value, the point of time will be recognized. The actual maximum value is overwritten by a higher value automatically, if it lasts more than 30 seconds. The determined values (max temperature/time stamp) can be cleared by the user. They are written into the parameter “Old time/value” after “Clear values” or after power off/on, “Master Reset” or “Device Reset”. The time/value is set to the actual time stamp, the max temperature value is set to the actual temperature value. By switching Temp max log off the values are not cleared, but the displayed values are set to zero. When exceeding the maximum temperature of 70° C the error message “Temp over limit” appears.

By changing the unit (from degC to degF or vice versa) the Temp max log values are cleared

Description of Flow URV logging function

The ow value is supervised constantly. As soon as the value reaches the upper limit value (103 %; 20.5 mA) event 1 is recognized. If this error condition remains actively longer than the hysteresis value, the limiting value recognition is activated, the overrun condition and the time stamp is stored. As soon as the ow value falls below the limit value, the supervision ends, the underrun condition and the event 2 time stamp is stored. For a new cycle the hysteresis time must pass.

After the recognition you can request the passed time: Time stamp from event1 till time stamp from event2: delta-Time The time difference is the time the upper limit was exceeded: hysteresis <= t <= delta-time

The actual cycle is overwritten automatically by a new one. The stored values will be cleared after power off. The default value for hysteresis is 30 seconds.

7.6.9 Trend conguration (Only available in HART 7)

Data Trending is intended to reduce the number of transmissions to get data from a device. This can be useful for monitoring applications that do not need to get all data with low latency. The RAMC supports the transmission of 1 trend information of a desired device variable.

When the Trend control is set from “Disabled”, to one of the following three settings the transmitter continuously calculates the trend data to be transmitted to the host.

Trend Control Function

Disabled No trend information will be calculated Enable single data point trending Only the value that was read during the occurrence of

the sampling will be kept in the ring buffer.

Enable ltered trending A ltered trend uses a time constant equal to one-third

of the trend sample period to smooth the data.

Consider a step change in the device variable value,

this averaging time constant allows the returned trend

value to reach 95 % of the step change in one trend

sample period.

Enable average trending The device averages the values that were taken during

the trend sample period.

The values to be transmitted are the following:

Trend Device Variable Parameter

Flow Flow in measurement unit Percent Percent value of ow Temperature Temperature in transmitter

The sampling interval is selectable in the range of 1 s up to 2 h. The internal measurement cycle is 250 ms. The RAMC supports one ring buffer with 12 samples in length. The ring buffer is updated with samples of the desired device variable value at the rate indicate by the sample period.

The trend data can be displayed in the following menu by applying the parameter “Refresh Trend Data” to the device.

All 12 trend data values will be displayed. When a Trend is not used it transmits NAN for the values and as status “bad / constant”.

8.1 Maintenance

8.1.1 Function test

Checking free movement of pointer:

- Remove housing cover.

- After deecting the pointer by hand, it must return to measurement value. If the pointer pivots to different values upon repeated deections, there is too much friction in the bearings. In this case, send indication unit to service.

Checking free movement of oat:

- First, free movement of pointer has to be ascertained.

- Check visually if pointer follows each ow rate change. If not, clean oat and measuring tube.

Unit with electronic transmitter:

- The display must show values corresponding to indication function and measuring unit settings.

- The bars under the 8 digits must not ash. If an error occurs, the corresponding countermeasure (refer to chapter 6.2.8 error messages) has to be taken or the unit has to be sent to service.

- Without ow, the output current must be 0 or 4 mA. At a ow rate of 100 % the current must be 20 mA.

Additional function test for HART units (-H, -J)

- check HART communication using a HART Handheld terminal or a PC with HART communication software.

- Setting: Device setup / Process variables

- PV AO shows the current value that should be delivered at output – Check this value using a multimeter.

8.1.2 Measuring tube, oat

The RAMC is maintenance-free. If contamination of the measuring tube impairs the mobility of the oat, the tube and the oat have to be cleaned. To do this, the RAMC has to be removed from the pipe. Replacement or cleaning of the oat:

- Remove RAMC from the pipe.

- Remove upper retainer from metering tube.

- Take oat stopper and oat out through the top of metering tube.

- Clean oat and metering cone.

- Insert oat and oat stopper into the metering tube.

- Set retainer into tube.

- Check oat for free movement.

- Install RAMC to the pipe.

Attention: Do not expose oat to strong alternating magnetic elds. The oat and especially its measuring edge must not be damaged.
