[. . . ] Warnings: Do not work on this unit before disconnecting it from the mains! The actuator is factory preset to a mains voltage of 230 V AC. Electric actuators do not have a safety position. In case of a mains breakdown, the actuator resp. [. . . ] ) Drive the actuator until one limit switch, is operated. The end positions can be adjusted by moving the switching cams, as the actuator follows them. S2 S1 54 GEORGE FISCHER . . . 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. For temperatures below ­@0 °C the heating element Nr. @43 should be installed (see Item 6. 6). 2) GEORGE FISCHER . . . 55 5. 2 Block Diagram open L 1 S1 S2 input voltage selection power supply overload protection 230 V 115 V closed 2 N 3 M 230 V 115 V reversing circuit 5. 3 Dimensions 84, 5 61 @46 85 64 @8@ 7 56 GEORGE FISCHER . . . 45 @48 6. Assembly and Connection of Modular Components The electrical actuator EA 20 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 electrical connection is made by means of a second cable plug or a threaded cable joint Pg (depending on the number of connecting wires). The respective kits are prepared for installation, the electric cables are cut to size and packaged accordingly. In the following sections, the corresponding assembly points and the wiring are illustrated.

Adjust the «Open» A and «Open» B (fine adjustment by moving the cams with a small screw driver). Move the actuator to position C (from B outgoing). Move the cam S3 by rotating clockwise to the change over point. Move the cam S4 by rotating anticlockwise to the change over point. Connect the D/E and connections according to diagram. Note: Do not insert the connections D/E and F yet. Caution: Connections to S3 and S4 are under supply voltage. Wiring diagram Nr.
