R-I CONVERTER RWG 1001

Application :This device is for the transformation of a resistance value into a proportionate current signal. It can be placed e.g. in actuators, where the position is determined by potentiometer and a 0/4-20mA signal is being brought out.Version :The components are enclosed in a plastic housing and covered by an epoxy fillingElectrical connection is by faston plug 2.8 x 0.5mm.As potentiometer transmitter preferably a potentiometer of 4.7k Ohm should be used, so that the reference voltage source is not overloaded.Block diagram :

MODE OF OPERATION :A reference voltage point Uref in the device (temperature compensated) delivers the supply voltage for the potentiometer transmitter. With the multiturn potentiometers P1 & P2 the position of the zero point and the total amplification can be adjusted over the input amplifier V1. The amplifier V2 converts the output signal from V1 into an output current of 0-20mA or 4-20mA. This is independent of the load within the range of 0 to 600 ohms. The lowest value 0mA or 4mA can be adjusted with P1.

SELECTION PROCEDURE

PART TURN VALVES : (E.g. : BUTTERFLY VALVES, BALL VALVES, PLUG VALVES, LOUVRE DAMPERS ETC.)In part turn valves, the final movement of valve shaft required is normally 900. The electrical actuators are primarily multi-turn type and hence it is necessary to employ an intermediate worm gearbox between the actuator and the valve so as to achieve 900 angle of rotation.Auma offers the following two types of worm gearboxes : Direct flange mounting type “GS” Foot mounting type “GF”Data required :

1. Type of valve2. Max. valve torque * (unseating torque)3. Type of service/duty4. Angle of travel (normally 900)5. Operating time required6. Shaft dia.7. Mounting flange details

* Note : In case of regulating/modulating service, max. (or unseating) torque and regulating (or running) torque are required for proper selection. Regulating torque should not exceed 50% of max. torque.

EXAMPLE Minimum data :

1. Max. valve torque = 7000Nm ( 700 kgm)2. Open - Close duty3. Operating time = 30 secs.4. Open - Close service

Step 1 : Selection of Gearbox Refer “Technical data” of gearbox catalogue (GS40-GS125 & GS160-

GS500) Select a gearbox type whose “Output torque for motor operation” is more

than or equal to required “ valve torque”. In this case, gearbox type is GS160 whose maximum torque capacity for motor operation is 8000Nm.Step 2 : Selection of Actuator Referring to the “Technical Data” of Gearbox catalogue, suitable multi-turn

actuator (given in the bottom row) to be selected.

auma india

Please note that economical sizing of actuator can be done by using higher reduction ratios considering operating time requirement. This is achieved by employing a primary reduction gearbox having different ratios.

Refer to the bottom-most row in the “Technical data” for different operating time in seconds for 900 at different actuator output speed.

In this case, 3 options are available for selection :Option 1 : Refering to first column of “Technical data” of GS160.

Model : GS160 with SA50E32 actuator.Operating time = 25 secs. (for 900)Actuator designation SA50E32 indicates open close duty actuator SA50 with output drive type E having output speed of 32.

Option 2 : Referring to the second column of GS160.Model : GS160 + GZ14 (216 : 1) with SA12E125 actuator.Operating time = 25 secs. (for 900)Where GZ14 in the primary reduction gearbox and 216:1 is the total reduction ratio of the gearbox.

Option 3 : Referring to the third column of GS160Model : GS160 + GZ14 (432:1) with SA6E180Operating time = 36 secs. (for 900)

Note : Always output drive type ‘E’ should be selected when coupling Auma actuator with Auma Gearbox.

Out of the above three options, any one suitable combination can be selected considering the operating time.After selecting the suitable model, following important points to be checked :1. Max. stem/shaft dia. (refer “Technical data” for details).2. Max. stem/shaft length acceptance (refer dimension ‘l max’ of dimension

sheet)3. Mounting flange compatibility (refer “Technical data” for details).

Note : i. The Selection procedure is same for foot mounted type worm gearboxes “GF”.

ii. In case of manually operated valves, select the gearbox model whose “output torque for manual operation” is more than or equal to required valve torque.

auma india

SELECTION PROCEDURELINEAR OR MULTI TURN VALVES

(E.g. : GATE, GLOBE DIAPHRAGM TYPE ETC.)For output thrust upto 190KN and output torque upto 100 kgm, Auma multi turn actuators can be directly selected and mounted on the valve. However, Auma also offers bevel gear boxes type “GK” and spur gear boxes type “GST” for upto and higher torque/thrust requirements.Data required :

1. Type of valve2. Max. thrust in case of rising stem valves.3. Max. torque in case of rotating stem valves.4. Type of service/duty.5. No. of turns of stem per stroke OR stroke and stem thread details.6. Operating time 7. Stem diameter8. Mounting details

EXAMPLE Minimum data :

1. Max. thrust = 300KN = 30000 kgf2. No. of turns/stroke = 203. Operating time = 60 secs.4. Open - Close duty

Step 1 : Selection of Gearbox Refer “Technical data” and “Output drive types” of gearboxes (GK10-35)in

catalogue. For rising stem valves, always output drive ‘type A’ to be selected. Select gearbox type whose max. thrust permissible is more than or equal to

required thrust. In this case, gearbox type is GK25.1 whose maximum thrust permissible is

320KN.Step 2 : Selection of Actuator Referring to the “Technical Data” of Gearbox catalogue (GK10-35), suitable

actuator model given in the table to be selected. The required output rpm of the actuator can be calculated as follows :

auma india

Actuator output rpm = No. of turns of valve/stroke x Reduction ratio of gearbox ------------------------------------------------------------------------------ x 60

Operating time in Secs. In this case, suitable actuator model in SA50

and 20 x 6

Actuator output rpm = --------- x 60 = 120 rpm 60

Choose the nearest available actuator output speed (refer Auma actuator catalogue for details) i.e. 125 rpm.Hence the selected combination is GK25,1A/SA50E125 and the revised operating time 52 secs.Where actuator designation SA50E125 indicates open-close duty actuator SA50 with output drive type E having output rpm of 125

Note : When coupling Auma actuator with Auma Gearbox, always output drive type ‘E’ should be employed.

Once the suitable model is selected, following points to be verified :1. Output torque capacity (refer “Technical data” for details).2. Max. stem acceptance dia. (refer “Technical data” and “output drive” for

details).3. Mounting flange compatibility (refer “Technical data” and “output drive” for

details).Note : 1. In case of multi turn non-rising (rotating) stem valves, same selection

procedure to be employed except the following. Output torque valves to be compared and evaluated. Output drive types B,C,D or E to be selected depending on type of

coupling required (normally the output drive type will be either ‘B’ or ‘E’)

2. The same selection procedure is applicable for Auma spur gear boxes “GST”.

TRANSPORT, STORAGE AND HANDLING INSTRUCTIONS

a) ACTUATOR :

Actuators are high-value Electro-mechanical devices. This should be taken into account during transport and storage. In order to avoid possible damages, inconvenience and costs for you land us please observe following points:1. TRANSPORT :

Transport to the place of installation in a sturdy packing. Ropes or hooks to lift or transport valves with mounted actuators

should not be attached to the handwheel. Fix ropes at valve and not at actuator. Output drive of actuator is

meant to mount actuators, but not to carry the whole weight of valve. Do not hit with handwheel against walls, floor or machine parts.

2. STORAGE :Even in watertight enclosed actuators condensed water collects due to temperature fluctuations. This may damage sensitive internal parts. Damages can be avoided by observing the following points: Store in well-ventilated and dry rooms. Protect against humidity from the floor by storage on wooden frame,

on pallets, in cage boxes or on shelves. Cover actuators with plastic foil to protect against dust and dirt etc. Protect suitably against mechanical damages. Check (at least random checks) after approx. every 3 months. In case

condensed water is inside switch compartment, all actuators have to be checked and, if necessary, dried out.

3. LONG-TIME STORAGE :In case actuators are stocked for a long period (more than 6 months) the following points must be observed additionally : Before storage: Protect bright surfaces, especially output drive parts

and mounting surface, by long-time corrosion protection agent. Check for possible corrosion approx. every 6 months. In case

corrosion has started, check all actuators and apply new corrosion protection wherever necessary.

4. COMMISSIONING :The caution advised for electric devices applies also for actuators. Especially safety instructions (such as VDE/TAB etc.) must be adhered too.Check visually for possible damages caused by transport or storage.Measure insulation resistance of motor before switching on. In case it is less than 500K Ohms this is an indication for humidity in the winding. Motor must be removed in order to dry. It can be heated with a hot-air fan or in an oven (NOTE : max. permissible temperature 1000 C).

auma india

Furthermore please refer to our operation instructions. In case they are not available with you, request a copy from us. The following points are very important :

- auma motors have thermo switches as standard. They must be integrated in the control circuit.

- Wrong connection or faulty control circuit may cause damage to valve or actuator.

- Bring valve manually to intermediate position, then check for correct sense or rotation. If wrong, switch off immediately and change direction. Limit and torque switches are ineffective if sense or rotation. If wrong, switch off immediately and change direction. Limit and torque switches are ineffective if sense of rotation is wrong!

1. TRANSPORT & STORAGE

- Transport to place of installation in sturdy packing- Do not attach to the hand-wheel ropes or hooks to lift by hoist.- Store in well ventilated, dry room.- Protect against humidity from the floor by storage in shelf or on wooden

frame.- Cover to protect against dust and dirt.- Apply corrosion protection agent to bright surfaces.

Ref : transport storage & handling section of manual

2. SERVICE CONDITIONS

AUMA multi-turn actuators can be used at following ambient conditions :

SA - 250 C + 800 C (Standard)

The types SA are designed for short time duty S2 – 15min.

3. MOUNTING TO THE VALVE/GEARBOX

Mounting & operation can be in any position

Check whether output drive flange suits the valve/gearbox. Check whether bore & keyway correspond with the input shaft of the

valve or gearbox. Degrease mounting surfaces at actuator and valve/gearbox thoroughly. Apply little grease to input shaft of valve/gearbox. Place actuator on valve/gearbox and fasten with bolts (quality min. 8.8)

firmly crosswise.

4. MANUAL OPERATION

Attention : Manual operation should only be engaged if motor stands still.

Push declutch lever as indicated by arrow. If resistance felt turn handwheel slowly while lever is pressed till manual driveengages.

Release declutch lever (snaps back to initial position by spring action). Manual drive remains engaged. In case lever does not snap back by itself assist with hand.

auma india

Manual disengages automatically when motor is started.

5. ELECTRICAL CONNECTION

For 3 phase Ac motor Check whether power supply (type of current voltage & frequency) suits

the motor (refer to motor name plate). Take off terminal compartment cover. Connect control wires according to wiring diagram (ref terminal plan

inside the terminal compartment cover).Connect earth to terminal marked.

Use suitable size cables for the glands supplied.

Attention : Enclosure IP67 is only guaranteed if correct cable sizes are used.

The two circuits of one switch are suitable only for the same potential. Different potentials require tandem switches.

Valve manufacturer decides whether switching off in end positions should be by limit (limit seating) or torque (torque seating).

AUMA motors have 3 thermo switches as standard in series. Full motor protection is guaranteed with correct connection of the

thermo switches. If these are not connected, our guarantee for the motor is invalid.

Clean sealing faces at cover for terminal compartment. Check whether O-ring is not damaged. Apply thin film of non-acid grease to sealing faces.

Place cover in position & fasten 4 screws firmly.

Tighten cable glands well to guarantee enclosure IP67.

6. TEST RUN

auma india

Remove cover at switch compartment and mechanical position indicator disc

Check whether limit switches tripped. Valve closed (WSR) valve open (WOL).In case tripped ref. pt. 7 for releasing.

Bring valve manually to intermediate position. Turn handwheel anti-closurewisefor OPEN & clockwise for CLOSE.

Check phase rotation. Switch on actuatorin direction ‘OPEN’. Check direction ofrotation observing arrows at limit switch counter gear. If sense of rotation is wrong,switch off immediately. Interchange any two incoming phases to the terminals RYB (RST).

Switch on again in OPEN direction. Presslimit switch flap WOL. Motor should stop. Repeat the same with DOL in OPEN direction. Motor should stop. Then control circuit is correct.

- If motor not switched off, press stop button.- Check control circuit & set it right. Determine overrun in both directions (overrun is turns/travel from

switching off till movement stops).

7. SETTING OF LIMIT SWITCHING Engage manual drive as explained under pt. 4

Setting for end position CLOSED. Turn handwheel clockwise till valve is fully closed. Consider possible

overrun as determined under pt. 6 Press down thrust bolt I and turn. The

bolt remains in this position. Turn spindleA in direction of arrow. Distinct clicks are felt & heard. Continue turning the spindle until the cam operates the switch. At this stage spindle should not click any more and should not be turned any further. If turned beyond inadvertently the point continue turning spindle slowly in the same direction till the switches cam goes back to its original tripping position. Turn thrust bolt I till it snaps back to its original position by spring action.

To test the correctness of above setting turn handwheel in opposite direction. The cam should release the switch flap immediately (i.e. for less than one turn of handwheel). In case of not releasing repeat the above steps again.

Setting for end position ‘OPEN’

Turn handwheel anticlockwise till valves is fully open. Consider possible overrun as in pt.6 by backwinding as required.

Set limit switching by spindle B procedure as explained above for end position ‘CLOSED’.

Check the correctness of setting as explained in ‘CLOSED’ setting procedure.

8. SETTING OF TORQUE SWITCHING

Attention : Adjusted torque must suit the valve.

If actuators have been supplied by a valve manufacturer, setting was made during testing. The setting should only be changed with the consent of valve manufacturer.

Figures on torque switch operating cam indicate values in Nm (1kgm 10Nm).Loosen screw & turn the cam till the desired torque coincides with arrow mark,then fasten lock screw.

If the actuators switched off by torque switch over its travel before reaching an end position please check whether valve stem is damaged or dirt adhering to it. If necessary and with valve maker’s consent the setting of tripping torque may be raised slightly.

9. SETTING OF MECHANICAL POSITION INDICATOR

Indicator disc rotates approximately 2700 at full travel from OPEN to CLOSE or vice versa.

auma india

A suitable reduction gearing was installed at our works. If turns per stroke are changed subsequently the reduction gears may have to be changed too.

Run actuator to end position ‘CLOSE’ Turn dial (CLOSE)till the arrow

is in alignment with the mark on theindicator glass.

Run actuator to end position ‘OPEN’ Turn dial (OPEN) while holding the

other dial position, till the arrow is in alignment with the mark on the glass.

10. MAINTENANCE

Attention : After commissioning, check for damages on paint caused by transport

or installation. Do necessary touch up to avoid corrosion.

AUMA actuators need only little maintenance. Precondition for reliable service is correct commissioning. It is also very important that the O-rings at covers are placed correctly and cable glands fastened firmly to prevent entrance of dirt or water.

We recommend :

If operated very seldom, perform a test run every six months. This assures that actuator is always ready to operate.

Approximately 6 months after commissioning and then every year check bolts between actuator and valve/gearbox for tightness. If required re-tighten.

The gear-housing was filled with lubricant in our factory. This filling lasts for several years of service.
