1. Introduction

This instruction manual contains all the informationregarding design, installation and start-up proce-dure for the electrical actuator unit Type EA 20.

Warnings:≠ Do not work on this unit before disconnecting it

from the mains!≠ The actuator is factory preset to a mains volta-

ge of 230 V AC. By all means refer to Item 2.1.≠ Electric actuators do not have a safety position.

In case of a mains breakdown, the actuatorresp. the valve remains in its actual position.

≠ Any work done on the actuator may only becarried out by authorized and trained person-nel.

≠ These products are according to the MachineGuidelines 98/37/EG (ancient 89/392/EWG),not regarded as machines; they are, however,built into installations which are regarded asmachines.

NoteWe distinctly emphasize that operation isprohibited until it has been confirmed that themachine (plant) into which the products havebeen built corresponds to the conditions of theEC Machine Guidelines 98/37/EG (ancient89/392/EWG).

2. Design of the actuator

The standard version of the electrical actuatorEA 20 consists of the following elements: spur-wheel gear, DC motor, power supply board aswell as components for l imit positioning. For speci-al applications, the actuator can be equipped withadditional modular components (see Item 6).

3. Design of Actuated Valve

The electrical actuator Type EA 20 can be moun-ted on a valve via a suitable intermediate housing.The actuators are delivered ex factory in the<open> position. Pictured below under 3.1 and 3.2are the assembly parts necessary for the automa-tic ball valve Type 111–113 and Type 115 fromGeorge Fischer. Both end positions are preset inthe factory. It is necessary to readjust them afterthe customer has assembled the unit (see Item 4).

≠ Fit the ball valve into the bottom half of bracket≠ Place the actuator with the top half of the

bracket on the ball valve, install the bracketclamps and fix with wedges.

4. Installation of the actuator

Warning:Before the actuator is connected to the mains, thefollowing must be checked:≠ is the actuator adjusted to the correct mains

voltage(see Item 2.@)

≠ are the electrical connections correct(see Item 2.2)

AdjustmentsIf a complete actuated valve is being supplied byGeorge Fischer, no further adjustments are neces-sary. If the customer assembles the unit or if arepair has been done, the end positions must bechecked and if necessary adjusted.Adjustments can only be done on dismountedvalves.

Limit switch positions:Switch S1 opens at «open» positionSwitch S2 opens at «closed» position(see diagram in the margin)

ProcedureBoth switching cams S1 and S2 are to be adjustedso that the actuating angle is less than 90° �) .Drive the actuator until one limit switch, is opera-ted. The end positions can be adjusted by movingthe switching cams, as the actuator follows them.

6. Assembly and Connectionof Modular Components

The electrical actuator EA 20 is equipped withfastening points which allow for additional modu-lar components to be mounted.

The configuration of these points is describedunder Section 2. The electrical connection is madeby means of a second cable plug or a threadedcable joint Pg @@ (depending on the number ofconnecting wires). The respective kits are preparedfor installation, the electric cables are cut to sizeand packaged accordingly.

In the following sections, the corresponding as-sembly points and the wiring are il lustrated.
