User manual GEORG FISCHER EA41

[. . . ] Introduction This instruction manual contains all the information regarding design, installation and start-up procedure for the electrical actuator unit type EA 41. Warnings: Do not work on this unit before disconnecting it from the mains! Any work done on the actuator may only be carried out by authorized and trained personnel. [. . . ] 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.

If the overload protection device has triggered, it will reset automatically when the unit has cooled down sufficiently and the actuator will operate again. 199 190 142/. . 143 should be installed (see Item 6. 5). 2) ¬ 51 5. 1 Block Diagram input voltage selection 230 V 115 V power supply overload protection <open> L <closed> 1 S1 2 3 S2 M N 230 V 115 V reversing circuit 5. 2 Dimensions 38 60 150 @02 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 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. In the following sections, the corresponding assembly points and the wiring are illustrated. ¬ 53 6. 1 Mechanical limit switches Description Kit with 2 additional auxiliary switches Kit with 4 additional auxiliary switches Kit with 2 additional auxiliary switches with gold contacts Technical Data 250V , 10 A 250 V , 10 A 4­30 V= 1­100 mA Code 199 190 138 199 190 139 199 190 149 1 Additional switching cams 2 Limit switch S5, S6 or S5 to S8 2 1 Wiring diagram Nr. 199 190 149 S5 S7 14 2 S6 14 2 M 2 S2 S1 S6 14 2 S5 14 2 M S2 S1 14 black white black red black white black black white black red FED 14 13 12 11 10 9 8 7 654N21 14 13 12 11 10 9 8 7 red FED 654N21 B A DC AC L1 N GND B A DC AC L1 N GND 54 ¬ 6. 2 Inductive limit switches The mechanical installation of these switches is identical to those under 6. 1.
