1. Introduction
This instruction manual contains all the information
regarding design, installation and start-up procedure for the electrical actuator unit Type EA 20.
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. By all means refer to Item 2.1.
≠ Electric actuators do not have a safety position.
In case of a mains breakdown, the actuator
resp. the valve remains in its actual position.
≠ Any work done on the actuator may only be
carried out by authorized and trained personnel.
≠ These products are according to the Machine
Guidelines 98/37/EG (ancient 89/392/EWG),
not regarded as machines; they are, however,
built into installations which are regarded as
machines.
Note
We distinctly emphasize that operation is
prohibited until it has been confirmed that the
machine (plant) into which the products have
been built corresponds to the conditions of the
EC Machine Guidelines 98/37/EG (ancient
89/392/EWG).

2. 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).

3. Design of Actuated Valve
The electrical actuator Type EA 20 can be mounted on a valve via a suitable intermediate housing.
The actuators are delivered ex factory in the
<open> position. Pictured below under 3.1 and 3.2
are the assembly parts necessary for the automatic ball valve Type 111–113 and Type 115 from
George Fischer. Both end positions are preset in
the factory. It is necessary to readjust them after
the customer has assembled the unit (see Item 4).

4. Installation of the actuator
Warning:
Before the actuator is connected to the mains, the
following must be checked:
≠ is the actuator adjusted to the correct mains
voltage
(see Item 2.@)
≠ are the electrical connections correct
(see Item 2.2)
S2
S1
Adjustments
If a complete actuated valve is being supplied by
George Fischer, no further adjustments are necessary. If the customer assembles the unit or if a
repair has been done, the end positions must be
checked and if necessary adjusted.
Adjustments can only be done on dismounted
valves.
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° 쏝) .
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.

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.
