Detailed instructions for use are in the User's Guide.
[. . . ] Introduction
This instruction manual contains all the information regarding design, installation and start-up procedure for the electrical actuator unit type EA 30. Warnings: ¼ Do not work on this unit before disconnecting it from the mains!¼ The actuator is factory preset to a mains voltage of 230 V AC. [. . . ] 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.

1)
The overload protection is designed to protect both motor and power supply board. If the overload protection device has triggered, it will reset automatically when the unit has cooled down sufficiently and the actuator will operate again. @43 should be installed (see Item 6. 5).

6. Assembly and Connection of Modular Components
The electrical actuator EA 30 is equipped with fastening points which allow for additional modular components to be mounted. The electrical connection is made by means of a second cable plug or a threaded cable joint (depending on the number of connecting wires). The respective kits are prepared for installation, the electric cables are cut to size and package accordingly. In the following sections, the corresponding assembly points and the wiring are illustrated.
