CV1500 Series Overview

1 . Safety Instructions:

DO NOT use AEL as a lifting mechanism!

Important: Requirements for professional qualification of people performing installation, service and maintenance:

Electric connection should only be performed by qualified electricians or electrical engineers. Service and connections should only be performed by qualified electricians or electrical engineers.

1 .1 Purpose and Application

Electric linear actuators (AEL) with electronic control of the AEL type are set up by the program to be controlled on the

24 V DC voltage level, or are set up by the program to be controlled by 4-20mA analog input signal.

Electric linear actuator type AEL are high-powered electric-mechanical products designed for direct installations onto controlled devices (regulating bodies - valves, etc.). AEL type actuators are provided for automatic control of regulating bodies in both directions of their movement. They are equipped to measure and control processes where an unified analogue direct current is needed.

1 .2 Warning for saftey use

Product protection:

There must be a suitable protective device in the supply power (circuit breaker or fuse) which also serves as the main switch. The AEL has its own short-circuit protection for the motor power supply circuits and space heater.

Type of equipment from a connection point of view: The equipment is designed for permanent connection.

Installation and Dismantling

4 Installing a control valve

Follow up with connecting the AEL with mains or master system.

1. Inspect control valve for any shipment damage and for any foreign material that may have collected during packaging and shipment.

2. Blow out all pipe lines to remove pipe scale, chips, welding slag and other foreign material.

3. Verify the flow direction marked on the body.

Note: a . Flow under the plug for parabolic trim .

4. Install the control valve, preferably in a straight run of pipe, away from bends or sections of abnormal velocity.

5. Control valves can be installed in any orientation. However the preferred installation is in horizontal pipeline with the actuator in a vertical position. However we can install control valve in other position.

6. If continuous operation is required during maintenance and inspection, a by-pass should be installed.

7. Install the valve using accepted piping practices. For flanged bodies use a suitable gasket between the body and pipe line flanges and tighten the bolts evenly to avoid any strain on the body or cracking of the flange.

8. An Armstrong drain separator (equivalent to line size) draining to a TVS trap is recommended to assure clean dry steam.

9. An Armstrong 100 mesh Y strainer should be installed before the control valve to reduce the chance of dirt fouling.

10. It is recommended to install pressure gauges before and after the control valve.

11. Piping immediately downstream of the control valve should be expanded to accommodate low pressure expansion. The pipe size should be chosen so a maximum velocity of 8,000 ft/min is achieved.

12. Install upstream and downstream gate valves to isolate control valve for maintenance and upgrades.

13. Install drains in-between control valve and isolation valves for depressurizing the line during maintenance.

14. Install a filter regulator on the air line to the actuator or positioner. The maximum air pressure to the actuator is 60 psig.

15. Tighten gland packing enough to prevent leakage, if packing is graphoil

4 .2 Electric Connection and Checking of Function

Follow up with connecting the AEL with mains or master system.

1. Follow instructions in section 1.2 on page 3.

2. While laying electrical line abide by the instructions for heavy current installations. Power supply cables must be of the type approved. Minimum thermal resistance of power supply cables and wires must be

176°F (+80°C).

3. Cables to terminal boards or connectors lead through cable glands.

4. Before putting AEL into operation, connect inside and outside grounding terminal.

5. Wires for input control signal to controller and output signals from current converter it is necessary to lead them separately with thrust wires or it is necessary to use shielded wires.

6. To prevent moisture from entering the actuator around the connecting cables, the cables must be sealed with silicone material at the point of penetration through device shell.

Connecting with the master system:

AEL can be controlled by:

• Analog signals through the buit-in controller.

• Binary inputs 24 V DC

AEL is connected according to wiring diagram under the cover of the AEL.

4 .3 Dismantling

Before dismounting, you must disconnect the AEL from power supply! Do not connect and disconnect live

connectors.

Step

1

Disconnect the AEL from the main electrical phases.

Step

2

Disconnect the leads from the AEL terminal boards and loosen the cables from the cable glands.

Step

3

Loosen the screws of the AEL flange and coupling and disconnect the AEL from the valve.

Adjusting Actuator

5 . Adjusting Actuator

AEL is delivered adjusted to parameters according to type and label from production plant. Adjustment is made to mechanical and electrical connected actuator. This section describes how to set up the AEL to parameter values within a range applicable for the software. Location of adjustable parts are on Fig . 7.

Adjustment is possible:

• By the control unit buttons (see Fig . 7)

• By the local control panel buttons – only for the AEL’s equipped with local control

Warning 1: When the input control signal is set to the value 0 - 20 mA (0 to 10 V), or 20 - 0 mA (10 to 0 V) and the input control signal fails, then the AEL keeps the position as with a 0 mA (0 V) input signal (AEL doesn’t recognize the difference between input signal failure and 0 mA (0 V) input signal).

Warning 2: Auto-calibration process will not run when the AEL is in error state, e.g. AEL is overloaded (AEL is switched -off from torque). In this case it is necessary to resolve issue, e.g. the AEL must be moved manually in a neutral position so it is not switching-off from torque and restart the auto-calibration again.

Warning 3: Calibration process must be performed with any change in the operating angle value of more than 10%

6 .2 Commissioning an AEL into Operation (starting the calibration)

If the AEL is delivered from manufacturing plant installed on valve, or with control device, calibration should be performed to ensure correct operation under actual pipeline conditions.

Procedure:

Fit the given assembly into the specified application

Connect the AEL to the supply voltage electrically according to the wiring diagram and chapter Electric connection and checking the function.

Move the AEL into the neutral position using manual control (see Warning presented above)

Switch on the supply voltage and switch to Auto Control.

Start the AEL calibration by pressing the P button on the control unit for 2 seconds at a minimum until LED ERROR (red), LED MENU (green) and LED PAR (red).

Release the P setting button

Release the P button to start the calibration procedure.

After the calibration procedure is finished, the AEL is prepared for its operation and starts to respond to control inputs

18

Procedures, Continued

6 .3 Commissioning an AEL into operation when it’s necessary to change the stroke (setting new end positions)

When an AEL is delivered without a valve or the actuator is changed to a different valve, and the setting of other parameters done by the producer suit your needs, and it is necessary to do a change to the AEL stroke.

Connect the AEL with the armature to be controlled (according to chapter 2) and fit this assembly into the specified application

Connect the AEL electrically according to the wiring diagram on page 30.

Turn on the power supply, without connecting the control signals fed into AEL (input control signal - AEL reports error/warning No.2 - no binary input)

Set the AEL using Manual Control to end position - closed. In Auto Control push button C for at least 2 seconds, until LED ERROR (red), LED MENU (green) and LED PAR (red) come on – the closed end position is then recorded in memory.

Release the C setting button

Set the AEL using Manual Control to end position - opened. In Auto Control push button O for at least 2 seconds, until

LED ERROR (red), LED MENU (green) and LED PAR (red) come on – the opened end position is then recorded in memory.

Release the O setting button

Using Manual Control put the AEL into the mid position (see Warning 2 above)

In Auto Mode press the P pushbutton on the control unit for at least 2 seconds . This will activate the AEL calibration until LED ERROR (red), LED MENU (green) and LED PAR (red) come on

Release the adjustment pushbutton P - upon release of the P pushbutton, the calibration process has started

Turn on the control signals, AEL is ready for operation and responds to control inputs

19

Service and Maintenance

7 . Service and Maintenance

In general it is provided that service of the AEL is performed by a qualified electrician in accordance with requirement given in section 1 on page 3!

At a power outage, an electric actuator will stop in a position, in which it had been before the power outage occurred. It’s possible to preset the electric actuator with manual operation.

Manual control:

If needed (during adjusting, function checking, failure etc.) control can be changed from automatic to manual by switching the side handle to the hand position.

• Instructions for manual control:

• Switch the power supply off.

• Turn the button for gear disengagement to the right by 90° (Fig. 11, the button arrow shows the symbol of hand) this disengages the gear in the actuator.

• Set the actuator to the chosen position: a) For actuators with manual control: push and turn the handle located on the actuator upper cover.

While turning counter-clockwisely the valve is turning in the direction “open”. Having the valve in the required position turn the button for gear disengagement to the position “automatic operation” this engages the gears

1)

. Put the handle back to its original position.

b) For actuators without manual control - using the fork wrench. Remove top cover, put fork wrench on 6-edged shaft of manual control. While turning counter-clockwise the valve is turning in the direction “open”. After resetting of the valve put the gear disengagement button to the original position

1)

and cover the actuator.

1)

After putting the button for disengaging of gearing again to the position of motor operation if the gearing is not connected it is needed to turn the handle to put the gears into mesh.

7 .5 Lapping Procedure

1

With metal seat trims, seating surface of the valve plug and seat ring can be lapped for improved shutoff. Deep scratches at seating surface may require a new seat.

2

Apply 1000 grit lapping compound to the seating surface of the valve plug; lubricate the spindle where it enters the packing box with light oil. Insert into the body, install bonnet

& secure it to body with 2 nuts and bolts diagonally opposite.

3

Produce a simple lapping tool. This can be made by welding a nut (same thread as plug spindle) to the center of a bar about 1 foot in length. Screw the tool to the end of the plug spindle.

Caution:

If the packing is to be re-used and was not removed from the bonnet, take care when installing bonnet to avoid damage to the packing from the valve stem threads.

4

Rotate the handle slowly by 60 deg. clockwise and counterclockwise in succession to lap the seat. Raise the plug occasionally, rotate by 90 deg. and lower it to another position and resume the oscillating rotation. This ensures an even lap over the entire seating surface of the plug and seat. The weight of the plug, stem and lapping tool provide sufficient pressure for lapping.

DO NOT APPLY ADDITIONAL

PRESSURE ON STEM FOR LAPPING.

After lapping, remove the bonnet (5), clean all the components & seating surfaces.

Repeat above procedure by using light oil instead of 1000 grit lapping compound. This will help fine lapping as well as ensure removal of traces of lapping paste from the sealing surfaces.

Remove the bonnet (5), clean all the components, particularly clean seating surfaces thoroughly.

Completely assemble as described in the ASSEMBLY portion below and test the valve for shut off.

Repeat lapping procedure if excessive leakage is still present. Metal to metal seating (ANSI Class IV) may not have a tight shut-off.

6

Apply a thin coat of anti-seize compound to all the, mating faces & screws (11).

Slide the bonnet over the spindle and install screws (11).

Caution:

If the packing is to be re-used and was not removed from the bonnet, use care when installing bonnet to avoid damage to the packing from the valve stem threads.

7

8

9

If packing is being replaced see replacing packing

Section G of the manual.

Use the proper bolting procedure during tightening so the joint between the body and bonnet will withstand test pressures and application service conditions. Before tightening the screws (11) make sure the plug spindle assembly is properly aligned with the seat ring.

Mount actuator and reassemble coupling as specified in

Section 4.1 of the manual.

Troubleshooting

8 . Troubleshooting

At failure of power supply the AEL stops in the position where it was before the failure. If needed the AEL can be set only with the manual control (the hand wheel). After restoration of power the AEL is prepared for operation.

Note 1: In some cases to remove an error, your shoud turn off the power supply for 3 seconds.

Note 2: One of the possible errors may be failure to return disengagement button afer the manual control to the position mechanical control, in such case, the AEL will remain standing.

• If AEL elements fail, it can be replaced with a new one. The producer’s service centre only is allowed for such replacement.

• If AEL fails, proceed please according to the instructions for the under guarantee and after-guarantee

• For repairing eventually the electronics use the fuse – see Fig.2 (F3) for example SHURTER MSF 250, or sub miniature SIBA 164550 xxx (see chapter 1.9.2), which is located on source board.
