Descriptions and Functioning
The EA SO 2-Ex are of the compact design with several connected modules. They consist of two
functionally different main parts.
The gear part is made of flange with a coupling for connection with the controlled part and gearings placed in
the bottom case; on the opposed side there are led drive mechanisms for units of the controlled part.
The control part (Fig. 1) is located on the control board (1), which contains:
•
an electric motor (2) (for the single-phase version it is with a capacitor )
•
a torque unit (5) – controlled by axial motion of a warm gear
•
a position-signalling unit (3) with a position transmitter (6) - resistive, capacitive or an electronic position
transmitter (6)
•
a space heater with (8) with thermal switch.
•
electric connection is realised using terminal boards (10) (located in the control area) and cable bushings,
or connector with cable bushings
Additional accessories:
Manual control: made up by a handwheel with a warm gearing
Local electric control module (Fig.12)
The SOR 2 version is equipped with an electronic controller (9). The position controller allows automatic
position adjustment of the EA output part depending upon the input signal value and provides also additional
functions.
