User manual GEORG FISCHER EA41

[. . . ] Any work done on the actuator may only be carried out by authorized and trained personnel. These products are according to the Machine Guidelines 98/37/EG (ancient 89/392/EWG), not regarded as machines; they are, however, built into installations which are regarded as machines. Note We distinctly emphasize that operation is prohibited until it has been confirmed that the machine (plant) into which the products have been built corresponds to the conditions of the EC Machine Guidelines 98/37/EG (ancient 89/392/EWG). 44 ¬ 2. Design of the actuator The standard version of the electrical actuator EA 41 consists of the following elements: spurwheel gear, DC motor, power supply board for the DC motor, transformer as well as components for limit positioning. [. . . ] Limit switch positions Switch S1 opens at <open> position Switch S2 opens at <closed> position (see diagram in the margin) Procedure Both switching cams S1 and S2 are to be adjusted so that the actuating angle is less than 90°). Drive the actuator until one limit switch, either <closed> or <open>, is operated. The end positions can be adjusted by moving the switching cams, as the actuator follows them. ¼ For George Fischer ball valves an exact 90°) rotation should be set. ¼ For George Fischer butterfly valves the <closed> position should be adjusted according to the following directions. S2 S1 ¬ 49 G/2 a Setting the <closed> position in actuators At the <closed> position in butterfly valves, the disk is not exactly vertical to the pipe axis. Deviation values can be taken from the following table. open a­b b DN mm 100 125 150 200 d mm 110 140 160 225 a­b mm 5 5 6 6 50 ¬ 5.

Assembly and Connection of Modular Components The electrical actuator EA 41 is equipped with fastening points which allow for additional modular components to be mounted. The configuration of these points is described under Section 2. The modular components are connected electrically over the free terminal points (7­14). The external wiring is done via a multiple wire cable through a threaded cable joint. The respective kits are prepared for installation; the electric cables are ready to use.
