Safety instructions and measures
1 Safety instructions and measures
The TROVIS5724-3 and TROVIS5725-3 Electric Actuators with Process Controllers are a
combination of an electric actuator and an integrated digital controller. They are designed
for operating a mounted globe valve. In combination with the valve, the actuator is used to
control the ow of liquids in the pipeline. The electric actuators with process controllers are
suitable for DHW heating applications.
The actuator is designed to operate under exactly dened conditions (e.g. thrust, travel).
Therefore, operators must ensure that the actuator is only used in applications that meet the
specications used for sizing the actuator at the ordering stage. In case operators intend to
use the actuator in other applications or conditions than specied, SAMSON must be con-
tacted.
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
section3.4.
Reasonably foreseeable misuse
The actuator is not suitable for the following applications:
− Use outside the limits dened during sizing and in 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
Qualications of operating personnel
The actuator must be mounted, started up, serviced, and repaired by fully trained and qualied 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 appli-
cable standards.

Safety instructions and measures
Personal protective equipment
No personal protective equipment is required for the direct handling of the electric actuator
with process controller. Work on the valve on which the electric actuator is mounted may be
necessary when mounting or removing the actuator from the valve.
Î Observe the requirements for personal protective equipment specied in the valve docu-
mentation.
Î Check with the plant operator for details on further protective equipment.
Revisions and other modications
Revisions, conversions or other modications to the product are not authorized by SAMSON.
They are performed at the user's own risk and may lead to safety hazards, for example. Fur-
thermore, the product may no longer meet the requirements for its intended use.
Safety features
The following safety features exist:
− Upon power supply failure, the TROVIS5725-3 Electric Actuator causes the valve to
move to a certain fail-safe position. The fail-safe action of SAMSON actuators is speci-
ed on the actuator nameplate.
Warning against residual hazards
To avoid personal injury or property damage, plant operators and operating personnel must
prevent hazards that could be caused in the control valve by the process medium, the operating pressure, the signal pressure or by moving parts by taking appropriate precautions. They
must observe all hazard statements, warning and caution notes in these mounting and operating instructions, especially for installation, start-up, and maintenance.
Responsibilities of the operator
The operator is responsible for proper operation and compliance with the safety regulations.
Operators are obliged to provide these mounting and operating instructions to the operating
personnel and to instruct them in proper operation. Furthermore, the operator must ensure
that operating personnel or third persons are not exposed to any danger.
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
well as the specied hazard statements, warning and caution notes. Furthermore, the operating personnel must be familiar with the applicable health, safety and accident prevention
regulations and comply with them.

Safety instructions and measures
1.1 Notes on possible severe personal injury
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.
Î Do not open the back housing cover.
The electric actuators with process controllers are protected against spray water
(IP54).
Î Avoid jets of water.
The switching output L' might be live after the supply voltage has been connected.
Î Do not touch the switching output L'.
Î When the switching output is not used, deactivate it in function F16 ('Passive' set-
ting).
Risk of bursting in pressure equipment.
Control valves and pipelines are pressure equipment. Improper opening can lead to
valve components bursting.
Î Before starting any work on the control valve, depressurize all plant sections con-
cerned 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.

Safety instructions and measures
1.2 Notes on possible personal injury
WARNING
!
Crush hazard arising from moving parts.
The form-t version of the electric actuator with process controller contains moving
parts (actuator and plug stems), which can injure hands or ngers if inserted into the
actuator.
Î Do not insert hands or nger 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.
1.3 Notes on possible property damage
NOTICE
!
Risk of actuator damage due to the power supply exceeding the permissible tolerances.
The electric actuators are designed for use according to regulations for low-voltage installations.
Î Observe the permissible tolerances of the power supply.
Risk of actuator damage due to excessively high tightening torques.
The connection of the electric actuator must be tightened with certain torques. Excessively tightened torques lead to parts wearing out quicker.
Î Observe the specied tightening torques.
Malfunction due to a conguration that does not meet the requirements of the application.
The electric actuator with process controller is congured for the specic application by
setting conguration items and parameters.
Î Perform the conguration for the specic application during start-up and after a re-
set to default settings.

Design and principle of operation
3 Design and principle of oper-
ation
The TROVIS5724-3 and TROVIS5725-3
Electric Actuators with Process Controller
consist of a linear actuator with an integrat-
ed digital controller.
They are especially designed for DHW heat-
ing in instantaneous heating systems for
small to medium-sized buildings and for
xed set point control circuits in mechanical
engineering applications. They are particu-
larly suitable for mounting to SAMSON
Types3213, 3214, 3260, 3222, and 3226
Valves.
A special version of Type3222 (DN25) and
Type3222N DN15) with a special plug de-
sign is available for small installations
(apartment or house). As a result, even small
tapping amounts can be controlled.
The integrated digital controller must be connected to a temperature sensor on the input
side, which can be optionally upgraded by a
water ow sensor or a ow switch.
Alternatively, a current signal can be used
for mechanical engineering applications.
The set point of the digital controller is set
to 60°C and can be changed manually at
the set point potentiometer (11) or in the
TROVIS-VIEW software.
The actuator contains a reversible synchronous motor and a maintenance-free gear.
The synchronous motor is switched off by
torque-dependent switches in the end positions or in case of overload. The force of the
electric motor is transmitted via gearing and
crank disk to the actuator stem (3) and to the
plug stem of the mounted valve.
