4.  WORK POSITIONOperating position MODACT MOA OC actuators is optional if the electric motor is not under the actuator, i.e.

the electric motor axis is not lower than 15 degrees below the horizontal level.

5.  DESCRIPTIONThe actuators are designed for direct mounting to the valve. The connection is made via a flange with B3 shape

according to ISO 5210 (Shape E according to DIN 3210), shape C according to DIN 3338. The arrangement of parts is shown in Fig 1. The three-phase asynchronous electric motor 1 drives a worm wheel via a countershaft gear, which is coupled to the output shaft of the actuator 8 through a switching clutch. Thereby the motor control transmits motion from the electric motor to the output shaft. The countershaft gear, worm, worm wheel, switching clutch and the output shaft are placed in the power cabinet 2. The switching clutch is provided with control lever 3 located outside on the side of the power cabinet, which also allows connecting the output shaft with the hand wheel 4 and thus manual control. In manual control it is necessary to push the control lever according to the instructions. Turning the hand wheel clockwise closes the valve. After the start-up of the electric motor the control lever and thus the clutch automatically return to the motor control position. To allow tripping of the electric motor upon reaching the desired torque on the output shaft, the worm is axially movable and axially sprung in both directions of movement. Its shifting distance then depends on the torque of the output shaft and the characteristics of the springs. The movement of the worm, which is then a measure of the torque at the output shaft, is transmitted to the control cabinet, where it is used for switching of the torque switches.

The output shaft is connected by means of the transmission gear with the units of positional and signalling switches, thereby enabling the electric motor to trip after reaching the desired position of the output shaft and remote indication of its position. All operating units, i.e. the torque control unit, position switching unit and signalling unit are located in the control cabinet 5. The contacts of theirs micro switches are completely interconnected with the actuator terminal board, which is located in the terminal box 6. This terminal board is also connected to the terminals from the electric motor (electric motor does not have its own terminal board).

The terminal box has one cable gland P 36 (7), which allows the sealing of the connection cable for connecting control and signalling circuits, and electric motor power supply.

The individual control units consist of mechanical drives and dedicated micro switches. They are positioned on a common control board (Fig. 2).

According to function they are the following:– Torque tripping unit 1– Limit tripping unit 2– Signalling unit 3

These units are universal for all sizes of the actuators are mounted on a common base plate 4.

Description and function of control unitsa)  Torque tripping unit (Fig. 3) as an independent assembly unit, it consists of base plate 19, which carried micro switches 20 and at the same time creates bearings for torque control shaft 22 and locking shaft 29. Torque control shaft transfers motion of the floating worm from power gear, using segments 23 or 24 and handles 45 or 46, to micro switches. Tripping torque value is adjusted by rotating the segments against the tripping handles. For possible tripping torque set-up outside the manufacturing plant, segments 23 and 24 are provided with a scale providing individually for each actuator indications of points for setting up the maximum and minimum torque. The set up torque is indicated by recesses in segments 27 and 28. Figures on the scale do not give direct indication of the tripping torque. Increments on the scale only serve to provide a more accurate division between the maximum and minimum torque levels, and thus to enable a more precise set-up of the tripping torque outside the manufacturing plant if no loading bench is available. Segment 23 is intended for “closing” direction, segment 24 for “opening” direction. The torque tripping unit is also fitted with a locking mechanism. The locking mechanism locks the torque switch once tripped and thus prevents it from re-triggering and thus also the actuator from pulsing. Apart from that the locking mechanism prevents the torque switch, after actuator rotation reversing, from tripping, and thus enables the electric motor’s breakaway torque to be fully utilized. The locking mechanism operates in both directions of motion of the actuator’s output shaft, both in limit positions and in the interim position, over 1 to 2 revolutions of the output shaft, after reversing of its motion. When the actuator’s output shaft is loaded by a restoring torque, the torque control shaft 22 rotates slightly, thus making segments 23 and 24 rotate two, which transfer the motion to tripping handle 45 or 46. As soon as the torque on the actuator’s output shaft achieves a value, to which the torque tripping unit has been set up to, the tripping handle will push the button of the relevant micro switch, which will disconnect the electric motor from power supply, and the actuator will stop.

Torque unit setting procedureTo set the tripping torque to another value, differing from the default value set at the manufacturing plant, proceed

as follows: release locking nut 44 (Fig. 3), and the relevant locking screw 25 (for “closing” direction) or 26 (for opening direction). Subsequently, put a screwdriver into the recess in the top segment 23 or 24 and rotate the segment until the recess in segment 27 or 28 points at the relevant point on the scale. This point is identified by dividing the difference between the maximum and minimum adjustable torque in Nm by the number of increments between the maximum and minimum torque signs. This approach shows us how many Nm of tripping torque falls on one increment on the scale. By interpolation, identify the point on the scale, to which the recess in segment 27 or 28 should point. The coloured line on the scale that is closer to number 10 indicates the setting point of maximum tripping torque, the other line identifies the setting point of minimum torque. The torque control unit must never be set up in a way that the recess in the bottom segment lies outside the area between the two coloured lines on the scale.

Once the tripping torque has been set up, tighten locking screw 25 or 26 and locking nut 44.

Tripping torque must be set at a higher value than those that correspond to the individual type designation in Table no. 1!

b)  Signalling unit (Fig. 4) secures transmission of electric signal of the actuator input shaft’s position. The unit is driven by gear 38 from the output shaft through the gearbox to cams 30, 31, controlling micro switches 36 and 37 37. The switching

moment of signal switches can be selected in any point of the actuator's working stroke, except the narrow area around end positions (signal switch must switch before the position switch while the output shaft is still moving). Top cam 30 operates in the “closing” direction and the bottom cam 31 operates in the "opening" direction.

Signalling unit is designed as a separate installation assembly. It is installed on bracket 39, below which gears are fitted, organized according to the kinematic diagram (Fig. 5). The transmission is set up so that adjusting gear K3 can be moved to various levels (I, II, III, IV, V) once locking screw 47 is released. By adjusting wheel K3, the setting range of signalling switches and transmitter will change depending on the working stroke. Next to figure 6 is a table specifying setting ranges corresponding to the various positions of adjusting gear K3.

Signalling unit setting

If the set up range of signalling switches needs to be changed, you have to change the position of adjusting wheel K3. To re-adjust wheel K3, you must partially slide the signalling unit out of the control box (the length of wires connected to micro switches allows it). This can be done after removing four screws 66 (Fig. 2), which hold the unit on the base plate. After resetting the signalling unit to the required range the securing screw 47 of the adjusting wheel K3 (Fig. 5) is secured with the wire lock and the unit is mounted back to its place. Before re-tightening screws 66, the check wheels K1 and K2 (Fig. 5) for correct meshing. Cams and micro switches of signalling unit are aligned as shown on Fig. 4. Cam toes 30 or 31 displace arms 34 and 35, which further operate micro switches 36, 37. When setting up signalling and position switches it is always necessary to re-align the actuator output shaft to a position, in which the micro switches are supposed to switch.

When adjusting the signalling switches, first release the screws 32 (for SQT2) or 33 (for SQC2) – Fig. 4. Than the cam 30 or 31 are turned in the direction of the arrow, until the micro switch triggers. In this position, hold the cams and re-tighten the locking screws.

At the lower end of the cam shaft 48 there is a pinion 49 which is connected to the shaft 48 via and adjustable friction clutch. The movement and propulsion of the resistance transmitter is sensed from this pinion.

NoticeAfter each handling with locking screws in the control part of the actuator, these screws must be secured from releasing by

vibrations, by dropping quick-drying varnish on them. If these screws had previously been secured using the varnish, the old varnish layer rests must be removed while adjusting, and the surface must be duly degreased and the screws must be painted.

c)  Position unit (Fig. 6)This unit secures switches SQT1 (PZ) or SQC1 (PO) to trip when the preset output shaft speed has been achieved.

The unit’s rotary motion is derived from the output shaft motion, by means drive wheel.This wheel turns stepwise the aligned gears, which control cam 57 (60). Cam turning to the roller of the switch SQT1

(PZ) or SQC1 (PO) will cause the switches to change over.

Handling and adjustmentThe unit is adjustable in the range from 2 to 250 revolutions. Adjustment procedure is as follows:

a) Once the actuator has been fixed to the valve, set valve to “closed“ position using the actuator.

b) In this position, push tripping rod 58 in vertical direction and then turn it by 90 degrees in any direction.

b) Turn the adjusting shaft 56 in “Z” arrow direction until the cam 57 pushes the spring of micro switch SQT1 (PZ) 63.

d) Turn the tripping rod 58 by 90°. Tripping rod will slip out again. If tripping rod fails to slip out, just very slightly turn shaft 56 or 59.

e) Use the actuator to move the valve by the required number of revolutions to "open" position.

f) Again push tripping rod 58 in vertical direction and then turn it by 90 degrees in any direction.

g) Turn the adjusting shaft 59 in “O” arrow direction until cam 60 pushes the spring of micro switch SQC1 61.

h) Turn tripping rod 58 by 90°. Tripping rod will slip out again. If tripping rod fails to slip out, just very slightly turn shaft 59 or 56.

Remark:Stop turning the adjusting shaft 56, 59 at the moment of switching!If, prior to adjustment, the cams are rotated by 270° compared to position in Fig. 6 or if cam has already pushed

the micro switch button, it is advisable to proceed adjustment as follows:

After pushing and turning tripping rod 58, turn the adjusting shaft 56 or 59 against arrows direction until the cam's tip leaves the micro switch lever (towards the closest adjusting shaft) and the micro switch switches (use suitable tester to make sure that micro switch has switched). Then turn adjusting shaft 56 or 59 in arrow direction to turn the cam’s tip back to the micro switch lever until the micro switch switches again (micro switch button) is pressed. Now the micro switch has been adjusted. Then slide tripping rod 58 out as described above.

d)  Resistance position transmitterResistive position transmitter has a nominal value of 100 Ω of resistance signal. The transmitter has a single-sided

shaft. At the end of the shaft there is a mounted wheelset 73 consisting of gears A and B.

Setting of position resistive transmitter

First of all, it is necessary to set up suitable gear ratio between actuator output shaft and transmitter shaft as per required working stroke of actuator – see table below.

Configuration is performed using the adjustable wheel K3 in the gearbox of the signal unit as per the previous paragraph b). Further, you must bring the necessary gear of the double wheel, affixed on the transmitter shaft, into meshing position. The wheel with the smaller diameter is marked A, the larger wheel is marked B.

The adjustment is made by moving the spacers 72 either under the transmitter support (wheel A is engaged) or above the transmitter support (wheel B is engaged). This is done at the position where the transmitter support is the most distanced from the gearbox.

Then the bolts securing the transmitter support are slightly tightened so as to be able to shift the transmitter support to a position where the A or B wheel are in engagement with the drive wheel. In this position, recheck the engagement of the wheels and possibly using the spacers on the shaft adjust the height of the wheelset to the free wheel. There must be a small play between the wheel A (or wheel B) and the driving wheel, so that the transmitter shaft is not stressed in the direction perpendicular to its axis. Then correctly tighten the mounting bolts of the transmitter bracket and secure with varnish. Select transmission ratio between wheel K 3 and gears A, B using the following table. If the required working stroke is in overlap of two zones, it is preferable to choose a lower band.

Upon setting the suitable gear adjust the resistive transmitter according to the following procedure:Due to the graduated gear ratio of the signal unit the potentiometer cursor does not move in the entire range

of the resistive track, but only in certain part. When setting the signal unit to the end positions “open“ and “closed“ according to paragraph b) the resistive transmitter is automatically set to a specific value.

Final setting of the transmitter is performed in the following manner:Adjust the output shaft of the actuator to the “closed“ position. Then loosen the screws of the transmitter contact

plates so that the entire transmitter can be rotated. Turn the transmitter then to set it to the lowest resistance value (approx. 4Ω, no less) and tighten the screws of the contact plates. When you turn on the actuator or turn the handwheel to “open“ the resistance begins to rise up to the resistance value corresponding to the end position “open“ (50 Ω to a maximum of 98 Ω). Thereby the transmitter is adjusted.

6.   PACKAGING AND STORAGEThe actuators are packaged together with the valve on which they are mounted. The packaging method applicable to

this valve assembly must be included in the technical conditions for the valves with the actuator mounted. During the transportation of the actuators from the manufacturer’s factory to the domestic valve manufacturer where the product is to be completed with the valve, the product must be covered. In such a case, the actuators are transported unpackaged. In the event of direct delivery of actuators without valves to the nuclear power plants the actuators are packaged according to a special regulation.

After receipt of actuators from manufacturer, actuators must be checked for possible damage suffered during transport. Compare if data on serial plates of actuators correspond with the accompanying documentation and the purchase order. Possible discrepancies, defects or damage must be immediately reported to supplier.

If the packed actuator is not installed immediately after receipt, it must be stored in dust-free room with ambient temperature between -50 °C and +50 °C, with relative humidity up to 75%, free from corrosive gases and fumes, protected from harmful climate impacts. If stored for a period longer than 1 year we recommend the oil charge to be replaced prior to commissioning. Any manipulation with the actuators at temperatures lower than -25 °C is forbidden. It is impermissible to store actuators outdoor or in areas unprotected from rainfall, snowfall and/or ice. Surplus preservative grease must be only removed before commissioning the actuator. When storing unpacked actuators for a period exceeding 3 months, we recommend you to insert a small bag with silica gel or another suitable desiccant material into the terminal box.

7.   VERIFICATION OF FUNCTION OF THE DEVICE AND PLACEMENTBefore starting to install the device, again check actuator for any damage suffered in the course of storage.

The function of electric motor can be verified by connecting it to power supply through a switch and by powering it up shortly. It is sufficient to observe if the electric motor starts up and if the output shaft starts rotating. Rotary actuators can operate in any position when the electric motor axis is not more than 15 degrees below the horizontal level. Actuators must be located in an area providing easy access to manual control wheel, terminal box and control box. Also, i t must be verified again if the location meets the provisions of section “Operating Conditions”. If local conditions require another method of installation, manufacturer’s approval must be obtained.

8.   INSTALLATIONSet actuator onto the valve so that its output shaft reliably fits into the valve coupling. Use four (eight) screws to connect

actuator with valve. Turn hand wheel to check correct connection between actuator and valve. Remove cover of terminal box and carry out electrical connection of actuator according to internal connection diagram.

9.   ACTUATOR ADJUSTMENTHaving fitted the actuator onto the valve and checked for correct mechanical connection proceed with the actual set-up

and adjustment.

1. Shift the actuator manually to an intermediate position.

2. Connect the actuator to power supply line, and shortly switch to verify correct rotation direction of the output shaft. When looking inside the control box, the drive wheel of the positioning units will rotate clockwise, while moving in “closing“ direction.

3. Electrically set actuator close to “closed” position, use hand wheel to arrive precisely at the “closed” position. In this “closed” position set the positioning unit (micro switch SQT1 (PZ) according to point 5c).

10

4. Set output shaft to a position, where the signalling switch SQT2 (SZ) is supposed to change over. Adjust SQT2 (SZ) switch according to instructions specified under point 5b).

5. Turn the actuator output shaft by the required number of revolutions (working stroke) and set the switch to SQC1 (PO) “open” position as described under point 5c).

6. Set output shaft of the actuator to the position, where the signalling switch SQC2 (SO) is supposed to change over. Adjust the SQC2 (SO) switch according to instructions specified under point 5b). Setting of positioning and signalling switches must be checked repeatedly.

Important notices

a) After mounting the valve with the actuator on the pipeline use hand wheel of the actuator to set the valve into its central position. Short-term running of the electric motor must be used to detect whether the actuator output shaft rotates in the correct direction, i.e., whether it responds correctly to the shutdown using the appropriate torque or positioning switches. Verification can be performed by pressing the handle of the respective switch with a suitable tool preferably made of insulating material or at least with a handle made of insulating material.

If the actuator does not rotate in the right direction, switch the two phase conductors at the terminal board of the actuator (terminals 1, 2, 3).

b) After mounting the valve with the actuator on the pipeline it is necessary to mount a pressure relief valve to the power cabinet of the actuator. For this purpose there is a power cabinet of the actuator provided with holes with plug bolts. A pressure relief valve is mounted into the uppermost hole instead of the plug bolt, whereby it must be ensured that the pressure relief valve axis is vertical.

c) The servo motor is equipped with gland outlet for sealing the supply cable, to which two rubber packing rings are supplied with the 23 and 26 mm openings. To seal the cable a sealing rubber ring is used according to the actual cable diameter. One ring is placed in the seal outlet, the other is located in the terminal box..

10.   OPERATIONCorrect operation of the MODACT MOA OC actuators is determined by operational conditions and is usually limited to

giving impulses for the various functional tasks. If necessary (e.g. during adjustment of the actuator) change the position of the controlled member by means of the hand wheel. The hand wheel is placed into engagement by means of the lever located on the side of the power cabinet. It is necessary to press the lever towards the valve and simultaneously rotate the hand wheel into such position that the clutch and the handwheel teeth are mutually engaged.

Operating personnel must ensure that the prescribed maintenance is carried out and that the actuator is protected against harming ambient impacts and weather conditions unspecified in section “Parameters of the working environment”.

11.   MAINTENANCEIf the oil does not flow from the power cabinet due to bad sealing, the oil charge is stable. Checking of oil and refilling is

carried out after two years. Oil charge should be changed after four years. The actuator is filled with PP 90 oil.

The amount of oil is shown in the following table:

Every four years it is necessary to lightly coat the teeth of the gear assemblies and rotary seats in the control cabinet with CIATIM 221 grease. To increase the corrosion resistance also grease springs in the control cabinet. Grease must not be applied on the sliing seats in the torque unit.

In all inspections and maintenance it is necessary to properly tighten all the nuts and bolts that have an impact on the creation of sufficient pressure on the rubber sealing, ensuring hermetic tightness of the actuator.

TroubleshootingActuator is in its end position, does not start up, motor buzzes. Make sure that all electric motor terminals (terminals 1,

2, 3) are energized. In the event that the slider is blocked so that it cannot be released with a hand wheel or a motor, it is necessary to dismantle the actuator from the valve and release the spindle nut mechanically.

MOA OC control actuators with resistive transmitter is in standard supplied without signalling micro switches (P0973 or P0974 diagram).

If the customer requires a signal micro switch, due to the lack of space on the terminal board the switching contacts of torque micro switches will not be outlet – this option must be specified in the order. (both variants are dashed in the wiring example).

Important advice:

If MOA OC actuators are used as control units, it is necessary that they are switched off in the end positions by positional micro limit switches!

If a tight seal is required, e.g. in the "closed" position, it is possible to switch off by torque, but with the following recommendation:

– regulation near the end of position “CLOSED“ (up to 10 %) is undesirable

– for short valve strokes the torque blocking must be as short as possible. Therefore, for this purpose, it is better to use MOA OC actuators in the version 20 07x.xxx1, where the blocking time between 1/4 and ½ of revolution of the output shaft of the actuator from the change of the direction of rotation.

– If the valve operation does not require torque blocking, we recommend ordering and using MOA OC actuators in 52 07x.xxxxM version. In this design the blocking of torque switches is excluded to both sides of rotation.

– The electric actuators can be supplied with a modified torque unit – without torque blocking to the closed side. 4 – 20 mA Converter

The converter is delivered as a separate mounting block for MOA OC and MOA actuators with resistive transmitter position. It transforms the signal of the 100 Ω resistive transmitter to a unified signal of 4 – 20 mA. The supplied converters are made by Treston, in the 222-224 RIPa/SO/BT III/ZOV design. They have an extended range of adjustability, even only 30% of the travel of the resistive transmitter can be converted to the output signal of 4 – 20 mA.

The Annex includes technical data and instructions of the converter manufacturer, which must be observed during assembly.

Setting procedure– Set the actuator limit switches and the resistive transmitter according to the Assembly Instructions.

– Connect the converter according to the manufacturer's recommendations and remove the cap that covers the two adjustment potentiometers..

– Set the range of the converter:

– adjust the actuator to the closed position and set the 4 mA current using the top potentiometer

– adjust the actuator to the open position and set the 20 mA current using the bottom potentiometer

– adjust the actuator to the closed and check the 4 mA current setting

– adjust the actuator to the open and check the 20 mA current setting

– if the values are set, cover the converter with the cap.

 INDUSTRIAL SIGNAL CONVERTERS TO MOUNT ON DIN TS-35 (IP 20) RAIL  Converter for resistive transmitters with current output of 4 - 20 mA 222-224 RIP

UseThe converters are designed to convert signal from the resistive transmitters to standardized current output of 4 - 20 mA.

DescriptionThe signal from the variable resistor is brought to the input of the converter. The resistance of supply conductors is fully

compensated. The circuit operates as a passive transmitter in current loop. The converter output serves also to its power supply. The converter is not equipped with galvanic isolation of input and output signal.

Work conditionsTemperature near the converter box may during operation reach a max. of +70 °C (upon request of client for a fee up

to +85 °C). The converter can be located at any position.

NoteGND terminal must be well grounded (on the chassis of the switchboard or to GND of the power supply). For the converter

with an input for potentiometer the maximum output current is at the connection of terminals no. 2 and 3.

Installation instructionsActivities under this section must be performed by at least knowledgeable personnel in accordance with section 5 of the

Decree no. 50/1978 Coll., respectively 51/1978 Coll. Converter

The 222-224 RIP converter (222-224 RIR) is attached by sliding on the DIN TS35 rail. First, place the top pin of the box holder to the top edge of the rail and with a screwdriver (max. 4 x 1 mm) gently pull the lock of the bottom locking pin. Press the bottom part of the box to the bar and then release the lock. Doing so will snap the box to the rail. Similarly, you can remove the box from the rail. The connecting cables should be connected as shown in Fig 3. If it is necessary to readjust the measuring range of the converter, it is possible to set the span and zero of the converter using a clockmaker’s screwdriver after previous removing the lid of the box. The position of the adjustment trimmers is shown in Figure 2. The recommended power supply for the converter is UNAZ stabilized power supply 24 V / 1.5 W (manufacturer TRESTON s.r.o.).
