2. EC Manufacturer‘s Declaration

The manufacturer, Georg Fischer Piping SystemsLtd, CH-8201 Schaffhausen, declares that thepneumatic actuators PA11/PA21 are not ready-to-use machines in the sense of the EC Directiveconcerning machines and cannot therefore meet allthe requirements of this directive.

¥ ‡ 5

Operation of these actuators is prohibited untilconformity of the entire system into which thevalve and the actuator have been installed isestablished according to the EC Directives listedbelow.

98/37 EG EC Machine Guideline

Modifications to the actuator which have aneffect on the technical data given in this instruc-tion manual and its intended use, i.e. signifi-cantly alter the actuator, render thismanufacturer‘s declaration null and void.

Warning

3. Intended Use

The descriptions and instructions in the followingapply to the pneumatic actuators:

Type PA11 Pneumatic part-turn valve actuatorDA/FC/FO

Type PA21 Pneumatic part-turn valve actuatorDA/FC/FO

When built into ‡ valves and connected to asystem control, the purpose of these actuators is toł actuate ball valves with a control pressure

of 2.8 to 7 bar and up to a driving torque of20 Nm, and

ł depending on the type of pneumatic actuator,double acting (type designation DA) or singleacting with spring for fail-safe to CLOSE (typedesignation FC) or single acting for fail-safe toOPEN (type designation FO),

¥ ‡6

ł control these valves to the OPEN and CLOSEDpositions via a built-in solenoid valve. The sole-noid valve must be either supplied ex ‡works or already mounted by the customer,

ł indicate these positions OPEN and CLOSED viaan electric signal to the system control, if theactuator is equipped for this with the respectivesubassembly,

ł enable control of these positions through manualoperation in case of failure in the compressed airsupply, if the actuator is equipped for this withthe respective subassembly.

The actuator is not intended for uses other thanthose stated here. Prohibited in particular are:ł control pressures above 7.5 bar,ł manual operation with forces higher than permit-

ted according to prEN12570 (maximum retentionforces for operation of valves),

ł operating solenoid valves and position feedbackunits under water.

The actuator can only function properly if it hasbeen connected professionally as per the wiringdiagrams on page 66 for double acting opera-tion and for fail-safe OPEN or fail-safe CLOSEoperation, respectively.

4. Safety Tips

4.1 Due care required of the operator

The pneumatic actuators described herein weredesigned and manufactured with consideration toa risk analysis and the respective harmonized Euro-pean standards. They correspond to the latesttechnology and meet the mentioned prescribedsafety standards.

Warning

¥ ‡ 7

Safety on the job can, however, only be realized ifall the necessary measures have been taken. It istherefore the responsibility of the system engineerand the operator of such systems into which thevalve with pneumatic actuator has been built toplan such measures and make sure they are carriedout.

The operator must make certain in particular thatł the valve with pneumatic actuator is only used as

it was intended for (see Section 3),ł the design parameters control air pressure and

voltage of electric subassemblies of the pneu-matic actuator, as indicated in the scope of or-der and delivery, are true and accurate,

ł the pneumatic actuator is only operated when inperfect working condition and the safety devicesfor the system supply of compressed air are re-gularly checked to make sure they are in perfectorder,

ł only qualified and authorized personnel plan,connect, and work with the actuator and thatemployees are instructed periodically in jobsafety matters according to the local regulations– especially as pertaining to electrical equip-ment, and

ł personnel is familiar with and observes this in-struction manual and the information containedherein.

4.2 Special hazards

Single acting, fail-safe OPEN and CLOSE (typedescription FO and FC) pneumatic actuators havepre-loaded springs that bring the valve into thepredefined position in case of compressed air loss.Dismantling these actuators is dangerous and mayonly be done by following special repair instruc-tions (available from ‡!) and under theguidance of a safety expert. Dismounting from thevalve may only be done in the safety position aftercutting off the compressed air supply.

Warning

¥ ‡8

Prior to any work on the electric subassemblies ofthe pneumatic actuator, the electrical connectionsof the control voltage should be disconnected.Any necessary live-line adjustments may only bedone with special insulated tools.

Furthermore, the operating instructions of themanual valve must also be observed. They arean integral component of this manual.

4.3 Transport and storage

The actuators must be handled, transported andstored with care. Please note the following points:ł The actuators should be transported and/or

stored in their original unopened packaging.ł The actuators must be protected from harmful

physical influences such as dust, heat (humidity).ł It is important that the connections are neither

damaged by mechanical nor thermal influences.ł Prior to installation, the actuators should be in-

spected for transport damages. Damaged actu-ators must not be installed.Warning

5. Actuator Design

The pneumatic actuator PA ¢1/PA2¢ features thefollowing components:ł Housing with screwed on spring cover, position

indicator and Namur air connectionł Spring cover with mounted, preloaded spring

assemblył Namur air connection with internal reversing

bore for the DA functionł Piston with rackł Pinion shaft

For special applications, actuators can be equip-ped with various supplementary kits/accessories.(see Accesssories).

The PA11 and PA21 pneumatic actuators can bemounted on ball valves type 546. By using the cor-rect coupling piece and selecting a suitable adap-ter plate, the actuators are connected to the multi-functional module with the provided clamps.Depending on the function of the actuator, FC,FO or DA, it is essential that the position of thevalve agrees with the position of the actuator.The individual components and how they are as-sembled with or without manual override areshown on page 64.

12. Fastening Plate

With the fastening plate for the ball valve type546, forces are absorbed which could occur duringvalve operation (e.g. initial breakaway torque). Inimplementing the fastening plate, working forcesare not transmitted to the piping system.

In piping systems which are subject to temperaturefluctuations, longitudinal or bending forces occur ifthermal expansion is hindered. So as not to impairvalve functioning, these forces must be absorbedby the appropriate fixed points in front of or behindthe valve.

The fastening plate is available in two sizes for thedimension range DN 10 to DN 50. Two screws tofasten on the ball valve are included in the scopeof delivery.
