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.

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).
