General safety instructions
1 General safety instructions
For your own safety, follow these instructions concerning the mounting, start up and opera-
tion of the actuator:
−The actuator is to be mounted, started up or operated only by trained and experienced
personnel familiar with the product. According to these mounting and operating instruc-
tions, trained personnel refers to individuals who are able to judge the work they are as-
signed to and recognize possible dangers due to their specialized training, their knowl-
edge and experience as well as their knowledge of the applicable standards.
−Any hazards that could be caused in the valve by the process medium and the operating
pressure or by moving parts are to be prevented by taking appropriate precautions.
−The actuator is designed for use in low voltage installations. For wiring and maintenance,
you are required to observe the relevant safety regulations. Only use protective equip-
ment in which the power supply cannot be reconnected inadvertently.
−Before wiring the actuator, disconnect it from the power supply.
To avoid damage to any equipment, the following also applies:
−Proper shipping and storage are assumed.
Note:
Devices with a CE marking fulll the requirements of the Directives 2004/30/EU and
2014/35/EU.

Design and principle of operation
2 Design and principle of op-
eration
The Type 3374 Electric Actuator is used in
industrial plants as well as in heating, venti-
lation and air-conditioning systems.
Theactuatorissuitableforform-tattach-
ment to various SAMSON valve series, and
with or without fail-safe action depending
on the version.
The stepper motor is switched off by
torque-dependent switches in the end posi-
tions or in case of overload. The force of the
motor is transmitted to the actuator stem via
gearing and ball screw.
Note:
On replacing a Type3374 Actuator
(revision 1) with a Type3374 Actua-
tor (revision 2), the wiring connection
of the binary input must be changed.
Instead of an external voltage supply,
a oating contact is needed. Other-
wise, the switching state cannot be
recognized.
Testing according to DINEN14597
TheType3374ElectricActuatorwithfail-ac-
tion "Actuator stem extends" is tested by the
German Technical Inspectorate (TÜV) ac-
cordingtoDINEN14597incombination
with various SAMSON valves. The register
number is available on request.
2.1 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 posi-
tion when the electromagnet is de-energized.
ÎDo not use the fail-safe action to control
the valve position!
2.2 Limit contacts
The actuator can be equipped with either
mechanical or electronic limit contacts to in-
uencethetasksofcontrolequipment.
2.2.1 Mechanical limit con-
tacts
The two mechanical limit contacts can be ad-
justed independently from one another. They
are operated by mechanical pins. The instal-
lation and adjustment of the mechanical limit
contacts is described in section 7.
2.2.2 Electronic limit contacts
The two electronic limit contacts consist of re-
lays 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 8.
