1. INTRODUCTION

1.3 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 specifications, 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 specifications as a consequence.

1.4 Principle of measurement

The RAMC is a Variable Area Flow Meter for volume and mass measurements of gases and liquids. A float, whose movement is nearly independent of viscosity is guided concentrically in a specially shaped cone. The position of the float 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.

F10.EPS

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 flow 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 fix the float 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 specified 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 influenced by external inhomogeneous

magnetic fields (such as solenoid valves). Alternating magnetic fields (≥ 10Hz) as well as homogeneous, static

magnetic fields (in the area of the RAMC), like the geomagnetic field have no influence. 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 RAMCs must be at least 300 mm.

2.3 Pipe connections

Ensure that the bolts of the flanges 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 specifications). While the system is pressurized the flange bolts must not be tightened or loosened.

3. INSTALLATION

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 flow rate meter must be installed in a vertical pipeline, in which the medium flows upwards. The vertical position has to be checked at the outer edge of the flanges. 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 flanges 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. Centre 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 flow. Please read also chapter 2-2. For further instructions on installation please refer to VDI/VDE3513.

3.2 Wiring of electronic transmitter (-E, -H) 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-dtype option /KF1). Unused glands must be closed with a blind plug M16x1.5. For wiring of RAMC with option /KF1 see chapter 10.6.2 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. The RAMC terminals accept wires with a maximum sectional area of 1.5 mm2.

Measuring and indicating instruments, connected in series to the output of the electronic transmitter, must not exceed a load impedance of

RL = (U - 13.5 V) / 20 mA — for 2-/3-wire RAMCs or 500 Ω for 4-wire RAMCs.

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)

- Heed the nominal voltage indicated on the scale.

- 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 housing must be grounded to ensure electro-magnetic interference protection. This can be done by grounding the pipeline.

- 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. Start of operation

4.1 Hints on flow rate measurement

The measured fluid should neither consist of a multi-phase mixture nor contain ferrite ingredients or large solidmass particles. The RAMC scale is adjusted to the state of operation/aggregation of the measured fluid 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 float 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 float have to be taken into account. To establish a new scale, please refer to the folder “Anweisung zur Skalenumrechnung” (Instructions for Scale Conversion) as well as the conversion table or order a new scale.

4.2 Pulsation and pressure shock

Pressure shock waves and pulsating flow influence measurement considerable or can destroy the meter.

Surge conditions should be avoided. (→ open valves slowly, raise operating pressure slowly)

If float bouncing occures in gases increase the line pressure until the phenomena stop. If this is not possible provide the float 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 flash. 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 configuration, 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 configuration, 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 /KN)

The optional limit switches are available as maximum or minimum type switches. They are proximity switches according to EN 60947-5-6 (NAMUR). Maximal two switches can be installed. The option (/Wnn) includes the respective transmitter relay.

These switches have been specified for hazadous area. However, the transmitter relay has to be installed outside any hazadous area.

The limit switches are connected to the transmitter relays as indicated in section 3-2. The terminals for the limit switches are on a small board on top of the transmitter case.

The MIN-MIN and MAX-MAX functions (refer to option /K3) 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 following table shows the assignment:

When using limit switches as a safety option, the switching directions for all combinations should be set to normal (inversion “OFF”) on the transmitter relay. To ensure functional safety the transmitter relay has to be applied as protection technology.

Please notice chapter 9.3 "Standard specifications".

For questions regarding protection technology, please consult your YOKOGAWA service centre.

6. ELECTRONIC TRANSMITTER (-E)

6. Electronic Transmitter (-E)

6.1 Operation principle

The position of the float 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 flow rate by the angle with calibration and operation parameters the calibration EEPROM. The flow rate is given as a current, either 0-20 mA or 4-20mA, and, in addition, indicated on the digital display (refer also to section 6-2). The electronic transmitters have been electronically calibrated before shipping and, therefore, are mutually exchangeable. Calibration data of the metering tube as well as customer specific 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 fluid data (e.g. specific 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 flow cut off is positioned at 5% of the end value. Below 5% flow 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 calibration

• Service functions

• Detection of float blockage

The setting of these parameters is done by two buttons.

The buttons access three functions:

- 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 flow rates from 0.0000001 uni/time to 106000 unit/time. Flow rate values exceeding 106000 are shown as ‘————’ on the display. In this case the next bigger flow rate unit (next smaller time unit) has to be selected. For the indication of totaliser 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 totaliser offsets are: Unit *1 Unit *1/10 Unit *1/100 The totaliser counts up to 99999999 or 9999999.9 or 999999.99 and is reset to zero. The next page shows the operating menu.

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 switchover between the two ranges with F31 the current output is automatically adjusted at equipments as of firmware version 1.4 . (s.F61 ). A perhaps necessary fine 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 fine adjustment can be carried out with F32 or F33.

The volume totalizer function in the angle-transmitter WT-MAG is available with a potentialfree 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 significant) digit of the totalizer. The higher pulse rate (lower solution) corresponds to the last but one digit of the totalizer.

6.2.7.4 Calculation of pulse rate

Concerning the final flow-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 transfered to a blank label of the also included sheet with unit-stickers and then fixed on the scale. After changing the flow 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 first row of the table below.

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

· The measuring unit is equal to the flow

Qmax ≤ 1 0.0001 0.001 1 < Qmax ≤ 10 0.001 0.01 10 < Qmax ≤ 100 0.01 0.1 100 < Qmax ≤ 1000 0.1 1 1000 < Qmax ≤ 10000 1 10 10000 < Qmax ≤ 100000 10 100

e.g..: Final value (Qmax ) = 400 m3/h

→ Pulse rate 0.1m

for F34-2 and 1m3 for F34-3

NOTE

• The factory default is F34 -2 (solution : 1 last digit).

• After Master Reset F34 -1 (Pulse output not activ) is selected.

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

redefined 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 calibration (F5-)

The relation of mm-to-flow rate is determined by the calibration process and reflected by the scale. The user can change this allocation by manual calibration. The unit can be reset anytime to the original calibration. Manual calibration can be performed when changing, for example, the measured fluid (density, temperature, viscosity) for the same measuring tube. In this case a new scale has to be established often, since the flow conditions have changed. Upon demand a calibration table for a given state of operation/aggregation is made available for each measuring tube. If you want to measure with the measuring tube in a different range, you either have to calculate the corresponding flow rate range on basis of the data in the calibration table (refer to instructions about RAMC scale conversion) or order a new scale. A new mm-to-flow rate assignment is the result. With the manual calibration function the current output is manually adjusted to a new scale. It is recommended instead of using using this function to buy a new scale and EEPROM. After activating the manual calibration function, the digital display only shows % (percentage). For the following preset flow rate values the new mm values must be calculated: 5%, 15%, 25%, 35%, 45%, 55%, 65%, 75%, 85%, 95%, 105% (11 values)

Execution:

Manual calibration is switched ON/OFF by the following functions:

F51-1 ENTER → Switched OFF F51-2 ENTER → Switched ON

At the time of shipping, the manual calibration table is identical with the measuring tube calibration table. The manual calibration table can be overwritten anytime by executing the following function: F52-5 ENTER 1st point F52-15 ENTER 2nd point F52-105 ENTER 11th point Place the RAMC (with measuring tube) horizontally on a table (the distance to ferro-magnetic parts must be at least 25 cm). By shifting the float, the pointer is set to the calculated mm values, starting from the 5% flow value (refer to display). After a short settling period (approx. 4 seconds) the mm value corresponding to this flow rate can be input by pressing both buttons (ENTER). After inputting all 11 values the manual calibration

table is memorized and can be activated. The inputting operation can be stopped by pressing button ↑.

Previous values, input by pressing ENTER, are retained in the memory.

6.2.14 Float blocking indication (F7-)

6.2.14.1 Function

Float

Pulsating movements of the flow medium (gasses, liquids) lead to fluctuations of the float and with that to fluctuations of the tap system/pointer. Therefore the electrical measuring signal permanently changes and with that the display value and the output current value. The fluctuations can be reduced with the help of the damping function “F21”. That shows however that the medium still flows and the float/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 float.

Basic noise

Since it is an electronic evaluation circuit, permanently minimal fluctuations of the measuring signal appear. The basic noise is caused by vibrations in the plant as well as by temperarture influences or external magnetic fields. The basic noise also appears, if

- no medium flows through the measuring pipe

- the float and with that the tap system are in the rest position

- the float/the tap system is blocked.

Float-Blocking-Indication

The function of the Float-Blocking-Indication allows the WT-MAG to distinguish the fluctuations, which are caused by a moving float, with the fluctuations of the basic noise to state a fault status. If the measuring signal does not exceed the autozero value during a defined 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 find 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 flash 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 first after a renewed autozero.

Autozero without flow

To execute the autozero function the following expiry is recommended:

- Plant in operation (measuring tube filled with medium)

- Drive flow to zero (place float into rest position)

- Raise the pointer to 10% to 20% of the flow and fix 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 flow can trigger the Float-Blocking-Indication

6-17

IM 01R01B02-00E-E

9th edition, July 2007

6. ELECTRONIC TRANSMITTER (-E)

Autozero with flow

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

- Plant in operation (measuring tube filled with medium)

- Move flow 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 flow 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 confirm the value.

Supervision range (measuring range)

The measuring range in which Float-Move-Detection is active lies between 5% and 105% of the maximum flow 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 flow 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 flashing (see fault behavior). Simultaneously the current output is set to a value, which enables a clear fault detection of a connected evaluation unit :

- 2 - wire 4-20 mA: Error condition: IA (IG) < 3,6 mA

- 3 - wire 4-20 mA: Error condition: IA < 0,0 mA

- 3 - wire 0-20 mA: Error condition: IA = 0,0 mA

6.2.14.3 Unsuitable applications

It is possible, that the Float-Blocking-Indication- Function does not work satisfactorily. This can be caused with different factors which are explained briefly 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 float-damping it can happen, that the pulsating movements of the medium (and with that of the float) 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 flow that the measuring signal lies below the autozero value, and a Float-Blocking-Indication is not possible.

Applications with quiet flow

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

Description of Flow URV logging function : The flow value is supervised constantly. As soon as the value reaches the upper limit value (103%; 20.5mA) (event 1), the time is measured, during the flow 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 flow 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.

Maintenance

8.1 Function test

Checking free movement of pointer:

- Remove housing cover (4 screws on housing type 66).

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

Checking free movement of float:

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

- Check visually if pointer follows each flow rate change. If not, clean float 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 flash. If an error occurs, the corresponding countermeasure (refer to section 6-2-8 error messages) has to be taken or the unit has to be sent to service.

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

Additional function test for HART

- check HART software.

- Setting: Device setup / Process variables

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

8.2 Measuring tube, float

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

- Remove RAMC from the pipe.

- Remove upper retainer from measuring tube.

- Take float stopper and float out through the top of measuring tube.

- Clean float and measuring cone

- Insert float and float stopper into the measuring tube.

- Set retainer into tube.

- Check float for free movement.

- Install RAMC to the pipe.

Attention: Do not expose float to strong alternating magnetic fields. The float and especially its measuring

edge must not be damaged.

9th edition, July 2007

8. MAINTENANCE

8.3 Electronic transmitter

The electronic transmitter is maintenance-free. The electronic section is sealed and cannot be repaired. Since the transmitter has been adjusted fully to the mechanical components at the factory, single components can only be replaced with a reduction of the accuracy. Solely the display and operation unit (LCD PCB) can be replaced. For this the unit has to be sent to service. The current output can be adjusted by means of software. The current output test in section 6.2.11 determines whether an adjustment is necessary. The adjustment is carried out according to section 6-2-6. The power supply PCB of 4-wire units includes a fuse. For fuse replacement be sure to switch off the power supply. Only use fuses with the capacity and characteristic as indicated in the specifications in section 9.3 or as imprinted on the fuse holder.

8.4 Exchange of EEPROM and scale

Preparations:

· Check the commissioning-no., the key-code and the data of the new parts.

· Switch off power supply.

- For units with option /KF1 wait more than 2 minutes before opening the indicator.

- For RAMC with housing type 91 unlock the safety screw at the cover.

· Remove the cover of the indicator unit.

· Make sure that all accessible parts are not under voltage.

The pointer may not be twisted or bent on the axis!

Exchange of EEPROM:

WARNING

The calibration-EEPROM can be damaged by electro-static discharge (ESD) . Therefore, only touch insulated parts and never terminals.

The EEPROM is plugged in on the right side of the electrical angle transmitters and safeguarded with a latch (s. fig 3-1 / 3-2).

· Unsrew the screw of the securing latch, but only a few turns!

· Turning the securing latch up, so that the EEPROM can be pulled out.

· Put in the new EEPROM (no wrong positioning possible).

· Turn the securing latch to below above the EEPROM and fix it with the screw.

Exchange of scale at units without limit switches:

· Unscrew the 2 screws of the scale.

· Pulling out the scale of the indicator unit to the left by raising the scale above the 4 corners for units with housing 66. For units with electronic transmitter the scale must additional raised above the 2 buttons.

· Sliding the new scale from the left under the pointer correspondingly until the 4 corner holes click in the footbridges for units with housing type 66 and the 2 buttons click in in the accompanying holes for unit with electronic transmitter.

· Fasten the scale with the 2 screws.

IMPORTAN

Exchange scale at units with limit switches:

Please, consult to this the service department of ROTA YOKOGAWA.

Final jobs :

· Connect the cover of the indicator.

- For RAMC with housing type 91 lock the safety screw.

· Switch on power supply.

· Check function of the unit.

IM 01R01B02-00E-E 9th edition, July 2007

8. MAINTENANCE

8.5 Exchange of indicator

The indication units may be replaced by units of the same type, on the condition that the scale of the measuring tube as well as the calibration EEPROM (in case of electronic transmitter) are mounted on the new unit. Operation for units with electronic transmitter (-E / -H) :

- Switch off power.

- For units with option /KF1 wait more than 2 minutes before opening the indicator.

- For RAMC with housing type 91 unlock the safety screw at the cover.

- Unscrew cover of indication unit.

- Disconnect cables and pull them through the cable glands out of the RAMC.

- Remove scale and calibration EEPROM from old indication unit and mount them to new indication unit.

WARNING

The calibration-EEPROM can be damaged by electro-static discharge (ESD) . Therefore, only touch insulated parts and never terminals.

The temperature graphs are reference values for size DN100. They may be influenced negative by trapped heat, external heat sources or radiated heat and influenced positive for smaller sizes. Insulation means rock wool between tube and indicator. Units with electronic transmitter can show the temperature of the internal transmitter on the display or HART-type can show and supervise the internal temperature by HART-communication. Units with PTFE lining are usable up to 130°C. For units with explosion proof certification the temperature limits according the certificate of conformity must be regarded (see also page 4 and 5). The minimum ambient temperature for indicators is -25°C except units with option /KF1 and /KS2 (lower temperatures on request).

10.1 General

10.1.1 Intrinsic safety

WARNING

To ensure intrinsic safety it is not permitted to repair or to modify the electronic transmitter, the display, the limit switches or the calibration EEPROM.

The electronic transmitters type -E/S1, -H/S1, -E/KS2, -H/KS2 and -G/S1 of the RAMC as well as the limit switches (option /K with option /S1) are intrinsically safe devices.

Power supply for the electronic transmitter and transmitter relay for the limit switches are associated apparatus and should be installed outside any hazardous area. The electronic transmitter must be connected to an intrinsically safe, certified power supply with a maximum voltage and output power below the maximum values of the electronic transmitter (refer to Technical data, in the concerning chapters). The combined internal inductance and capacity of the

electronic transmitter and connecting cables must be less than the permitted external inductance and capacity of the power supply. Accordingly, the limit switches have to be connected to intrinsically safe, certified isolating switching amplifiers. The relevant maximum safety values must be heeded at all times.

Especially in the case of high fluid temperatures, heated metering tubes or heat radiation by heat tracing, make sure that the temperature in the indicator housing does not exceed the permissible maximum ambient temperature of the transmitter (refer to Technical data, chapter 9).

10.1.2 Flame proof

In the RAMC with option /KF1 the transmitter and the limit switches are mounted in a flame proof housing. Wait 2 minutes after switching power off before opening the cover. The cover can only be opened after loosing the safety screw. After closing the cover the safety screw must be fixed before switching power on.

The RAMC with option /KF1 shall be connected up via suitable cable glands and / or conduit systems that satisfy the requirements of EN 50018 or 60079-1 sections 13.1 and 13.2 and for which a separate test certificate is available. Cable gands and entry fittings (screwed conduit entries) as well as blanking plugs of simple design may not be used. On connection of the RAMC /KF1 using a conduit entry approved for the purpose, the associated sealing facility must be arranged directly on the housing. Unused openings must be closed off as defined in EN 50018 section 11.9 (e.g. certified blanking elements). The RAMC with option /KF1 shall be connected to the local equipotential grounding system.

10.7.2 Installation

The electrical connections to the electronic transmitter and to the limit switches must be made via suitable cable glands and / or conduit systems that satisfy the requirements of EN 50018 or EN 60079-1 sections 13.1 and 13.2 and for which a separate test certificate is available. The cables, cable glands and stopping plugs must be specified for an ambient temperature of 100°C. Cable gands and entry fittings (screwed conduit entries) as well as stopping plugs of simple design may not be used. On connection of the RAMC /KF1 using a conduit entry approved for the purpose, the associated sealing facility must be arranged directly on the housing. Unused openings shall be closed with certified stopping plugs in type of protection flame proof enclosure "d" (100°C). Secure cable glands, stopping plugs and the safety screw for the cover against twisting. For installation in areas with combustible dust EN50281-1-2 must be considered.

CAUTION

The RAMC with option /KF1 shall be connected to the local equipotential grounding system. Therefore a grounding screw is available outside on the indicator housing and inside the indicator .

The electronic transmitter and the limit switches shall be wired as described in chapter 3.2.

10.7.3 Operation

If the cover of the indicator unit has to be opened, following instructions must be followed.

CAUTION

1. Switch off the power supply.

2.Wait 2 minures after power is turned off before openeing the covers.

3.The cover is fixed with a special screw.

4.Be sure to lock the cover with special screw after tightening the cover.

5.Before starting the operation again, be sure to lock the cover with the locking screw.

6.Users are prohibited from making any modifications of specifications or physical configuration, such as adding or changing the configuration of external wiring ports.

WARNING

The instrument modification or parts replacement by other than authorized representatives of YOKOGAWA is prohibited and will void the certification.

WARNING

If the window of the cover is damaged the RAMC must be set out of operation..
