Design and principle of operation
3 Design and principle of oper-
ation
The actuator contains a reversible synchronous motor and a maintenance-free gear.
The motor is switched off by torque-dependent limit contacts or in case of overload.
The force of the motor is transmitted to the
actuator stem (3) via gear and crank disk.
When the actuator stem extends, the actuator piston (3) pushes against the valve's plug
stem. When the actuator stem retracts, the
return spring in the valve causes the plug
stem to follow the movement (force-locking
connection).
Actuator and valve are connected by the
coupling nut (4).
Type 5824 without fail-safe action
This actuator without fail-safe action has a
handwheel (2) used to manually position the
valve. Travel and direction of action can be
read off the travel indication scale (9).
Type 5825 with fail-safe action
The actuator contains a spring mechanism
(8) and an electromagnet. The actuator is
moved by the force of the spring to the failsafe position when the electromagnet (termi-
nals L and N) is de-energized. The direction
of action depends on the actuator version
and cannot be reversed.
The Type 5825 Actuator is available with
fail-safe action "actuator stem extends" or
"actuator stem retracts".

EB 5824-1 EN 13
Design and principle of operation
Î The fail-safe action must not be used to
control the valve position.
The Type 5825 Actuator does not have a
handwheel (2) on the housing cover. Manual
override is possible, after removing the front
cover, using a 4mm Allen key. The actuator
returns to its original position as soon as the
Allen key is released.
Version with faster motor
The Types5824-13/-23/-33 and
Types5825-13/-23 have a more powerful
motor in a housing at the back of the actuator.
Testing according to DINEN14597
The Types5825 Electric Actuator with fail-
safe action "actuator stem extends" is tested
by the German technical surveillance association (TÜV) according to DINEN14597 in
combination with various SAMSON valves.
The register number is available on request.
3.1 Cover screws
The actuator housing cover is fastened using
TORX PLUS
®
screws, size 10IP.
Î To loosen and tighten the screws, the fol-
lowing screwdrivers can be used:
− TORX
®
T10
− TORX PLUS
®
10IP
− Flat-blade screwdriver with 0.8mm
blade thickness and 4.0mm blade width
3.2 Additional equipment
− The resistance transmitter is linked to the
gear and produces a resistance signal
between approx. 0 and 1000Ω (useable range 0 to 800Ω ) proportional to
the valve travel. The resistance transmit-
ter is not suitable for retrotting.
− On request, the actuator can be tted
with two limit contacts. Optionally, the
actuators can be equipped with two limit
contacts, which are actuated by continuously adjustable cam disks.
The power supply as well as the inputs
and outputs are not galvanically isolated.
The two additional limit contacts are not
suitable for retrotting.

The travel indication scale has two opposed
scales. Which scale is to be used depends
on the valve version (Fig.2). In the delivered
state, the scale alignment applies to globe
valves and three-way diverting valves. The
alignment needs to be changed when a
three-way mixing valve is used (see below).
Globe and three-way diverting valves:
the driving pin is in position 0 (delivered
state).
Three-way mixing valve:
change the alignment of the scale.
Î Carefully open the housing cover.
We recommend screwing the bottom screws
of the open housing cover into the top holes
of the housing.
Î Remove scale, turn it and replace it so
that the pin is positioned over the appro-
priate hole (6, 12 or 15) corresponding

The actuator stem must be retracted before
the actuator can be mounted onto the valve.
The stem can be retracted either mechanical-
ly or electrically. Both methods are described
below.
Retracting the actuator stem mechanically
1. Unscrew front cover and place a 4mm
Allen key on the red actuating shaft.
2. Retract the actuator stem: Turn Allen key
counterclockwise only and only as far as
the nal travel value which is at the point
where the torque-dependent limit switch
is activated (see Fig.4).
Risk of damage to the actuator by turning it
too far.
Only retract the actuator stem as far as the
nal travel value.
3. Hold Allen key in place and fasten valve
and actuator together using the coupling
nut (tightening torque 20Nm). Remove
Allen key and carefully refasten the front
cover.

Mounting and start-up
Retracting the actuator stem electrically
1. Unscrew front cover.
2. Perform electrical wiring according to
Fig.6 on page26 and carefully refasten the front cover.
3. Retract actuator stem:
Switch on power supply and retract the
actuator stem electrically until it reaches
the end position (voltage applied to eL
and N or using controller).
Risk of damage to the actuator due to incorrect connection of the voltage.
Do not apply a voltage to eL and aL at the
same time.
4. Fasten valve and actuator together using
the coupling nut (tightening torque
20Nm).
Fail-safe action "actuator stem retracts"
Î Place the actuator on the valve connec-
tion and tighten coupling nut (tightening
torque 20Nm).
5.1.4 Type5825: form-t
attachment
Î For fail-safe action “actuator stem re-
tracts” and “actuator stem extends”,
mount actuator as described in sec-
tion5.1.2.
NOTICE
!
5.2 Installing the control valve
into the pipeline
Î Install the valve into the pipeline accord-
ing to the mounting and operating instructions of the valve.
Î The control valve can be installed in the
pipeline in any desired position. However, a suspended mounting position of the
actuator is not permissible (see Fig.5).
The IP54 rating can only be achieved up
to device index .03 when the actuator is
installed in the upright position. See the
last two gures of the conguration ID on
the nameplate (see p.11) for the index.

5.3 Electrical connections
Risk of electric shock.
− Upon installation of the electric cables, you
are required to observe the regulations
concerning low-voltage installations ac-
cording to DINVDE0100 as well as the
regulations of your local power supplier.
− Use a suitable power supply which guar-
antees that no dangerous voltages reach
the device in normal operation or in the
event of a fault in the system or any other
system parts.
− Connect the actuator to the electrical net-
work only after the power supply is rst
switched off. Make sure the power cannot
be switched on unintentionally.
− If voltage is applied to eL, the actuator
motor retracts the actuator stem.
− If voltage is applied to aL, the actuator
motor extends the actuator stem.
Risk of damage to the actuator due to incorrect connection of the voltage.
Do not apply a voltage to eL and aL at the
same time.
5.3.1 Connecting the power
supply
Î Connect the wires through the cable en-
tries (1.2, Fig.1) according to Fig.6.
Î The interference suppression capacitors
in the output circuit of the connected con-
troller must not exceed a value of 2.5nF
to ensure the proper functioning of the
actuator. A special actuator version is
available on request for connection to
controllers with larger interference suppression capacitors.
Î Connect actuators operated in parallel
over separate contacts to prevent the actuators hunting in the end positions due
to a shared OPEN or CLOSED contact.
Î Connect power supply to terminals L and
N in Type5825.

6.1 Limit contacts
Risk of electric shock from exposed live
parts.
Do not touch live parts on adjusting the limit
contacts.
The limit contacts (6, Fig.1) can optionally
be used as make or break contacts.
Terminal assignment (Fig.6):
− Terminals 41, 44, 42:
à
Bottom cam disk,
adjuster 7.1
− Terminals 51, 54, 52:
à
Top cam disk,
adjuster 7.2
1. Unscrew front cover.
2. Move the actuator stem to the position at
which switching point is to be activated.
3. Use a 4mm Allen key to turn the adjust-
ers (7.1 or 7.2 in Fig.1) up to the point
where the contact is triggered.
The angle of rotation of the cam disks is limited. Therefore, use preferably the top adjust-
er (7.1) for the upper travel range and the
bottom adjuster (7.2) for the lower travel
range.
6.2 Resistance transmitters
As the valve passes through its travel range,
the resistance value changes from 0Ω to approx. 80% of its nominal value. Turn a
screwdriver placed on the slotted shaft to
calibrate the resistance transmitter.
Calibrating the actuator with an extended
actuator stem at 0Ω
1. Connect ohmmeter to terminals 61 and
62 (see Fig.6).
2. Extend the actuator stem to its end posi-
tion.
3. Turn the resistance transmitter counterclockwise as far as it will go. The ohmmeter indicates the initial value of ap-
prox. 0Ω.
Calibrating the actuator with a retracted
actuator stem at 0Ω
1. Connect ohmmeter to terminals 61 and
63 (see Fig.6).
2. Retract the actuator stem to its end position.
3. Turn the resistance transmitter clockwise
as far as it will go. The ohmmeter indi-
cates the initial value of approx. 0Ω.
4. Only for actuators with 6 or 12mm
travel: Slowly turn the resistance transmitter counterclockwise up to the point
where the resistance changes from 0Ω.
