1 Safety instructions and measures

The Type3374 Electric Actuator is designed to operate a mounted globe valve used in
industrial applications as well as in heating, ventilation and air-conditioning systems. The digital positioner ensures a predetermined assignment of the valve position to the input
signal. The actuator is designed to operate under exactly dened conditions (e.g. thrust,
travel). Therefore, operators must ensure that the actuator is only used in applications that
meet the specications used for sizing the actuator at the ordering stage. In case operators intend to use the actuator in other applications or conditions than specied, contact
SAMSON. SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external factors.
Î Refer to the technical data for limits and elds of application as well as possible uses. See
section3.6.
Reasonably foreseeable misuse
The actuator is not suitable for the following applications:
− Use outside the limits dened during sizing and by the technical data
Furthermore, the following activities do not comply with the intended use:
− Use of non-original spare parts
− Performing service and repair work not described in these instructions
Qualicationsofoperatingpersonnel
The actuator must be mounted, started up, serviced and repaired by fully trained and quali­ed personnel only; the accepted industry codes and practices are to be observed. Accord­ing to these mounting and operating instructions, trained personnel refers to individuals who are able to judge the work they are assigned to and recognize possible hazards due to their specialized training, their knowledge and experience as well as their knowledge of the appli­cable standards.
Safety instructions and measures

DANGER
Risk of electric shock.
Î Before connecting wiring, performing any work on the device or opening the de-
vice, disconnect the power supply and protect it against unintentional reconnection.
Î Only use power interruption devices that are protected against unintentional recon-
nection of the power supply.
Î Do not remove any covers to perform adjustment work on live parts.
Risk of bursting in pressure equipment.
Valves and pipelines are pressure equipment. Improper opening can lead to valve components bursting.
Î Before starting any work on the valve, depressurize all plant sections concerned as
well as the valve. Î Drain the process medium from all the plant sections concerned and from the valve. Î Wear recommended personal protective equipment. See associated valve docu-
mentation.

1.2 Notes on possible personal injury

!
WARNING
Crush hazard arising from moving parts.
The electric actuator contains moving parts (actuator and plug stems), which can injure
hands or ngers if inserted into the actuator.
Î Do not insert hands or ngers into the yoke while the valve is in operation. Î Disconnect the power supply before performing any work on the control valve. Î Do not impede the movement of the actuator or plug stem by inserting objects into
their path.

Design and principle of operation

3 Design and principle of oper-
ation
The Type3374 Electric Actuator is used in
industrial plants as well as in heating, venti­lation and air-conditioning systems. The actuator is suitable for form-t attach­ment to various SAMSON valve series, de­pending on the version with or without fail- safe action. The stepper motor is switched off by torque-dependent switches in the end posi­tions or in case of overload. The force of the motor is transmitted to the actuator stem via gearing and ball screw.
The Type3374 Actuator is optionally avail­able with either integrated yoke (Fig.1) or using an M30x1.5 ring nut (Fig.2) including
the necessary stem connecting parts.
TestingaccordingtoDINEN14597
The Types3374 Electric Actuator with fail-
safe action "actuator stem extends" is tested
by the German technical surveillance associ­ation (TÜV) according to DINEN14597 in
combination with various SAMSON valves. The register number is available on request.
Fig.1: Construction with integrated yoke

3.1 Versions

The Type3374 Electric Actuator is available
with or without fail-safe action.
Version with fail-safe action
Type 3374-2x and Type 3374-3x Actuators are able to perform a fail-safe action and contain a spring assembly and an electromag net. The actuator moves to the fail-safe posi­tion when the electromagnet is de-energized.

Design and principle of operation

3.2 Limit contacts

The actuator can be equipped with either mechanical or electronic limit contacts to in-
uence the tasks of control equipment.
3.2.1 Mechanical limit con­tacts
The two mechanical limit contacts can be ad­justed independently from one another. They are operated by mechanical pins. The instal lation and adjustment of the mechanical limit
contacts is described in section6.1.
-

3.2.2 Electronic limit contacts

The two electronic limit contacts consist of re­lays with changeover contacts. In contrast to the mechanical limit contacts, the electronic limit contacts no longer function after a power supply failure. The relays are de-energized and the contacts change to the idle state. The
retrotting and adjustment of the electronic limit contacts is described in section9.8.

3.3 Manual override

There are two ways to manually move the actuator stem:
− Manual override with 4mm hex wrench
− MAN operating mode to move the actu- ator stem manually

3.3.1 Mechanical override

The mechanical manual override is only pos­sible for actuators without fail-safe action. It
is performed by placing a 4mm hex wrench
on the red actuator shaft located at the side of the housing. The hex wrench is included in the scope of delivery. It is attached to the bottom of the housing.
Î Do not operate the manual override
while the actuator is running and only when the power supply is disconnected.

3.3.2 Moving the actuator stem manually

First place the actuator into MAN mode to move the actuator stem manually. The oper­ation and selection of the operating mode
are described in section8.1 on page42.
EB 8331-4 EN 13
Design and principle of operation

3.4 Communication
