Design and principle of operation
3 Design and principle of oper-
ation
TheType3375ElectricActuatorisusedin
industrial plants as well as in heating, venti-
lation and air-conditioning systems.
The actuator is a linear actuator which is
controlled by a three-step signal. Depending
on the version with or without fail-safe ac-
tion, it is particularly suitable for mounting
onSAMSONSeries240and250Valvesas
wellastoType3214Valve(DN300and
400).
Principle of operation
The electric actuator consists of a reversible
asynchronous motor and a maintenance-free
planetary gear with ball screw drive. The ac-
tuator is switched off by torque-dependent
limit contacts (2). Additionally, the asynchro-
nous motor is protected by a thermal fuse.
3.1 Fail-safe action
The actuator versions with fail-safe action
contain a spring mechanism and an electro-
magnet. The actuator is moved by the force
of the spring to the fail-safe position when
the electromagnet (terminals L and N) is
de-energized. The direction of action de-
pends on the actuator version and cannot be
reversed.

3.2 Additional equipment
Mechanical limit contacts
Optionally, the actuator can be equipped
with two limit contacts. They consist of two
changeover switches. Their switching posi-
tions are changed independently from one
another by continuously adjustable cam
disks.
Thelimitcontacts(4)aresuitableforretrot-
ting. The installation and adjustment of the
mechanical limit contacts is described in the
'Installation' section.
Resistance transmitters
Optionally, the actuator can be equipped
with resistance transmitters. They are linked
to the gear and produce a resistance signal
betweenapprox.0and1000Ω(usable
range0to900Ω)proportionaltothevalve
travel. It can be used to assess the position of
the actuator stem.
The resistance transmitters (1) are suitable
forretrotting.Theinstallationandadjust-
ment of the mechanical limit contacts is de-
scribed in the 'Installation' section.
