ATTENTION
1 Intended use
The electric actuators EA 25/45/120/250 are designed for assembly on a valve and for
connection to a system controller.
The electric actuators EA 25/45/120/250 are intended to activate valves with rotating
movements up to 180° (e. g. ball valves and butterfly valves).
The product is not intended for any types of use other than those described here. Nonobservance of the instructions contained in this manual will void the manufacturer's warranty
for the products mentioned above.

5.3 Principle of operation
The actuator runs by switching the voltage from the OPEN position to the CLOSE position.
By switching the voltage to the other input, the actuator runs from the CLOSE position
to the OPEN position.
The end positions are factory set to 0 and 90°. Additionally, any 3rd position (MIDDLE position)
can be adjusted, which is located between the OPEN position and the CLOSE position.
This position is not assigned at the factory.
End positions and Middle position can later be changed via the end position buttons, see
Chapter 9.2 “Adjusting end positions”, Page 61.

GF actuators are always delivered in the OPEN position.

5.3.2 LED status feedback
The LED status feedback shows the valve positions and the current status of the actuator.
The following table shows the color assignment of the LED:
If the plant standard requires an inversion of the color assignment, the customer can adjust
this afterwards, see Chapter 9.3 “Inverting LED color assignment”, Page 61.
