User manual GEORG FISCHER EA20

[. . . ] Design of the actuator The standard version of the electrical actuator EA 20 consists of the following elements: spurwheel gear, DC motor, power supply board as well as components for limit positioning. For special applications, the actuator can be equipped with additional modular components (see Item 6). 543 2 1 Limit Switch S1 und S2 2 Spindle for additional switching cams 3 Mounting space for additional limit switches 4 Mounting space for potentiometer and/or operating time adjustment module 5 DC motor 6 Visual position indicator valve closes valve opens 16 1 Spur-wheel gear 2 Unit plug 3 Connector terminal strip for external connections max. 1, 5 mm 2 4 Electrical supply unit 4 3 1 2 GEORGE FISCHER . . . 49 2. 1 Mains Voltage Selection 230 V, 50­60 Hz The actuator is factory preset for 230 V [. . . ] 270°, set to 90° @2 Nm 25 Nm ­@0° to +50 °C 2) 0­98%, non-condensing PP fiberglass reinforced external screws rust-proof visual, integrated Power consumption Protection Duty cycle Overload protection Electric connection Control time Angle of operation Continuous torque Peak torque Operating temperature Permissible humidity Body material Position indicator 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. 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@ 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 electrical connection is made by means of a second cable plug or a threaded cable joint Pg 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.
