3 Design and principle of oper-
ation
The TROVIS5757-7 Electric Actuator with
Process Controller is a combination of a linear actuator and an integrated digital controller. The combination is especially designed for heating applications as well as for
xed set point control of heating systems in
small to medium-sized buildings. It is partic-
ularly suitable for mounting to SAMSON
Types3222, 3222N, 2488 and 3267
Valves (DN15 to 25) as well as to special
versions of Type3226 and Type3260
Valves.
The digital controller is connected to a ow
sensor on the input side, which can be op-
tionally upgraded by a return ow, outdoor
or room sensor. In addition to the Pt1000
input, the digital controller has a potentiome-
ter input (1000 to 1100Ω or 1000 to 2000
Ω) to measure the ow temperature. This input inuences the heating characteristic in
the case of outdoor-temperature-controlled
control and the room temperature set point
in the case of xed set point control with
room temperature inuence. The heating
characteristic and set point can be changed
over the TROVIS-VIEW conguration software.
The output signal of the integrated digital
controller acts over the positioner on the synchronous motor of the actuator and is transferred over the connected gear to the actuator stem (3) and used as the positioning
force.
The motor is switched off by torque-dependent switches when an end position is
reached or in case the motor is overloaded.
The actuator is mounted onto the valve using
a coupling nut (4).
When the actuator stem extends, the valve is
closed, opposing the force of the valve
spring (7). When the actuator stem retracts,
the valve is opened as the plug stem (6) follows the motion of the return spring.

Slider switch (red)
Fig.2: Position of the slider switch
The slider switch allows you to switch be-
tween two different congurations #1 and
#2. In position #1, the slider switch points
away from the housing and in position #2
towards the middle of the housing. In both
levels #1 and #2, the functions described in
section10.2 can be activated and the asso-
ciated parameter settings made. The default
settings is the same for both levels #1 and
#2, except for function block F13. Changes
to functions and parameters can be made
over the TROVIS-VIEW software.
The position of the slider switch determines
which function and parameter settings (level
#1 or #2) is used for closed-loop operation.

5.3 Electrical connections
!
DANGER
Risk of electric shock.
− Upon installation of the electric cables, you
are required to observe the regulations
concerning low-voltage installations according 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.
− The switching output L' is live. Do not touch
the switching output L'.
The actuator requires a Pt1000 temperature
sensor (e.g. Type5267-2) to be connected to
measure the ow temperature.
Depending on the control task, an outdoor
sensor (e.g. Type5227-2) or room panel
(Type5257-7 only) can be connected. They
can all be combined with a return ow sensor (e.g. Type5267-2).
Additionally, the actuator has a potentiome-
ter input 1000 to 1100Ω (e.g. Type5257-
7) or 1000 to 2000Ω. This input is used to
correct the room set point (±5K) in case of
EB 5757-7 EN 19
Page 20
Mounting and start-up
xed set point control with room temperature
inuence (uKH5757-7). On using an out-
door sensor, it can change the adjusted heating characteristic (uKH5757-7). The
non-oating switching output can alternatively be used as an output for an external
demand for heat.
The connected sensors are monitored for line
breakages. A fault in the line of a sensor is
indicated by the red LED blinking (underneath the cover on top of the circuit board).
Each sensor has its own blinking pattern (see
section3.2). In the event that several sensors
are defective, the LED blinks using the sequence for the sensor with the highest priority:
Highest priority Flow sensor
Outdoor sensor or
room sensor
Return ow sensor
Lowest priority Potentiometer
The actuator stem extends and the red and
yellow LEDs are illuminated located under
the cover on top of the circuit board.
As soon as the actuator stem has reached
the nal position, the red LED is turned off.
The yellow LED remains illuminated and indicates that the actuator is ready for use.
5.4 Conguring the electric actuator
The actuator is congured with the
TROVIS-VIEW software. All the functions and
parameters are listed in section10.2.
Information
The Conguration Manual uKH5757-7
can be found in the Help menu of the
TROVIS-VIEW software. The manual contains a detailed description of each function
and parameter.
Example: In the event that the ow sensor
and outdoor sensor are defective, the LED
initially blinks to indicate that the ow sensor
is defective. When this fault is eliminated, the
LED then blinks to indicate that the outdoor
sensor is defective.
Î Perform the electrical connection depend-
ing on the heating application according
to one of the following wiring diagrams
(Fig.5 to Fig.7). As soon as the actuator
is connected to the power supply, the ini-
tialization procedure starts.

start-up, the valve with electric actuator is
ready for use.
Î Switch off the power supply.
Î Turn clockwise to extend the actuator
stem (approx. 4 turns for 1mm travel).
6.1 Manually changing the stem position
Î Turn counterclockwise to retract the actu-
ator stem (approx. 4 turns for 1mm trav-
el).
The stem must only be manually positioned
when the power supply is switched off as the
stem position is determined by the process
controller in closed-loop operation, meaning
any manual adjustment would be automatically corrected.
