1. Introduction

This instruction manual contains all the informa­tion regarding design, installation and start-up
procedure for the electrical actuator unit type
EA 41.

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
not regarded as machines; they are, however,
built into installations which are regarded as
machines.

98/37/EG (ancient 89/392/EWG),

44

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 41 consists of the following elements: spur­wheel gear, DC motor, power supply board for
the DC motor, transformer 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 41 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 butterfly valve type 035 as well as
the automatic ball valve type 108 from George
Fischer. Both end positions (open and closed)
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 2.1)

–are the electrical connections correct?

(see Item 2.2)

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,
either <closed> or <open>, is operated.
The end positions can be adjusted by moving the
switching cams, as the actuator follows
them.

쐌 For George Fischer ball valves an exact

90°쏝) rotation should be set.

쐌 For George Fischer butterfly valves the

<closed> position should be adjusted accord­ing to the following directions.

6. Assembly and Connection
of Modular Components

The electrical actuator EA 41 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 modular components are
connected electrically over the free terminal
points (7–14). The external wiring is done via a
multiple wire cable through a threaded cable
joint. The respective kits are prepared for installa­tion; the electric cables are ready to use.

In the following sections, the corresponding
assembly points and the wiring are illustrated.

switching cams S1 and S2 see Item 5
adjusted incorrectly

Motor only runs in throw-over relay does not replace power supply
one direction function board

Transformer gets wrong input voltage see Item 3.2
very hot selected

Overload protection friction torque of valve clean and lubricate
triggers (self resetting) too high valve

defective motor replace motor

duty rating too high increase cycle time

apply measures to
