Safety instructions and measures
1 Safety instructions and measures
TheTROVIS5724-8andTROVIS5725-8ElectricActuatorswithProcessControllersarea
combination of an electric actuator and an integrated digital controller with two PID control
modules. They are designed for operating a mounted globe valve. In combination with the
valve,theactuatorisusedtocontroltheowofliquidsorvaporsinthepipeline.Theelectric
actuators with process controllers are suitable for closed-loop operation in heating and cool-
ing applications.
Theactuatorisdesignedtooperateunderexactlydenedconditions(e.g.thrust,travel).
Therefore, operators must ensure that the actuator is only used in applications that meet the
specicationsusedforsizingtheactuatorattheorderingstage.Incaseoperatorsintendto
usetheactuatorinotherapplicationsorconditionsthanspecied,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.
ÎRefertothetechnicaldataforlimitsandeldsofapplicationaswellaspossibleuses.See
section3.6.
Reasonably foreseeable misuse
The actuator is not suitable for the following applications:
−Useoutsidethelimitsdened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
Qualications of operating personnel
The actuator must be mounted, started up, serviced, and repaired by fully trained and quali-
edpersonnelonly;theacceptedindustrycodesandpracticesaretobeobserved.Accord-
ing 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.
ÎObservetherequirementsforpersonalprotectiveequipmentspeciedinthevalvedocu-
mentation.
ÎCheck with the plant operator for details on further protective equipment.
Revisions and other modications
Revisions,conversionsorothermodications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:
−Anactiveblockingprotection(A8.3congurationitem=1,seesection10.2)intheelec-
tric actuator with process controller prevents the valve from seizing up.
−Uponsupplyvoltagefailure,theTROVIS5725-8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 operat-
ing 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 oper-
ating 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, operators must ensure that
operating personnel or third persons are not exposed to any danger.

EB 5724-8 EN 7
Safety instructions and measures
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
wellasthespeciedhazardstatements,warning,andcautionnotes.Furthermore,theoper-
ating personnel must be familiar with the applicable health, safety and accident prevention
regulations and comply with them.
Referenced standards and regulations
The electric actuators with process controllers comply with the requirements of the European
Pressure Equipment Directive 2014/30/EU and 2014/34/EU. This declaration of conformity

1.3 Notes on possible property damage
NOTICE
!
Risk of actuator damage due to the supply voltage exceeding the permissible toler-
ances.
The electric actuators are designed for use according to regulations for low-voltage in-
stallations.
ÎObserve the permissible tolerances of the supply voltage.
Risk of actuator damage due to excessively high tightening torques.
The connection of the electric actuator must be tightened with certain torques. Excessive-
ly tightened torques lead to parts wearing out quicker.
ÎObservethespeciedtighteningtorques.
The display does not work due to an interrupted cable connection.
The cable connection for the display is located underneath the front housing cover.
ÎOnly open the front housing cover to perform actions described in these instructions.
ÎDo not disconnect the connecting cable between the actuator and housing cover.
Malfunction due to a conguration that does not meet the requirements of the appli-
cation.

Design and principle of operation
3 Design and principle of oper-
ation
TheTROVIS5724-8andTROVIS5725-8
Electric Actuators with Process Controllers
contain two integrated digital controllers, re-
ferredtoascontroller[1]andcontroller[2]
inthefollowing.TheTROVIS5724-8iswith-
outfail-safeactionandtheTROVIS5725-8
has fail-safe action.
The electric actuators with process controllers
aremountedontoSAMSONTypes3222,
3213,3214,2488,42-36E,3226and
3260 Valves as well as Series V2001 Valves
uptonominalsizeDN50.
The actuator contains a reversible synchro-
nous motor and a maintenance-free gear.
The force of the motor is transmitted to the
actuator stem via gearing and cam disk.
When the actuator stem extends, it pushes
against the valve's plug stem. When the ac-
tuator stem retracts, the return spring in the
valve causes the plug stem to follow the
movement (force-locking connection). The
valve and actuator have a force-locking con-
nection.Aform-tconnectionisusedfor
special valve models, e.g. Series V2001
valves.
The user can read and change the set point
and operating values at the control panel.
All other parameters can be changed in the
TROVIS-VIEW software. Data between the
actuator and computer is transferred either:
−OverBluetooth(rmwareversion1.1x)
−OverModbus(rmwareversion2.1x)
After a supply voltage failure, the electric ac-
tuator starts again by performing a zero cal-
ibration and uses the last valid setting.
TheTROVIS5725-8ElectricActuatorswith
fail-safe action largely corresponds to the
previouslydescribedTROVIS5724-8.How-
ever, they also include a spring mechanism
and an electromagnet.
3.1 Fail-safe positions
TROVIS5724-8
TheTROVIS5724-8ElectricActuatorwith
Process Controller does not have fail-safe ac-
tion. When a valve is mounted on this actua-
tor, the valve remains in the last position af-
ter the supply voltage fails.
TROVIS5725-8
TheTROVIS5725-8ElectricActuatorwith
Process Controller has fail-safe action. When
a valve is mounted on this actuator, the valve
ismovedtothefail-safepositionspeciedon
thenameplate(seeitem12insection2.1)
after the supply voltage fails.
−Actuator stem extends: upon supply volt-
age failure, the actuator stem extends.
−Actuator stem retracts: upon supply volt-
age failure, the actuator stem retracts.

Preparation
4 Preparation
After receiving the shipment, proceed as fol-
lows:
1. Check the scope of delivery. Compare
the shipment received against the deliv-
ery note.
2. Check the shipment for transportation
damage. Report any damage to SAM-
SON and the forwarding agent (refer to
delivery note).
4.1 Unpacking
Do not remove the packaging until immedi-
ately before mounting and start-up.
1. Remove the packaging from the electric
actuator.
2. Dispose of the packaging in accordance
with the valid regulations.
4.2 Transporting and lifting
4.2.1 Transporting
−Protect the electric actuator against exter-
nalinuences(e.g.impact).
−Protect the electric actuator against mois-
ture and dirt.
−Observe the permissible transportation
temperatureof–20to+70°C.
4.2.2 Lifting
Due to the low service weight, lifting equip-
ment is not required to lift the electric actua-
tor.
4.3 Storage
Risk of actuator damage due to improper
storage.
−Observe storage instructions.
−Avoid long storage times.
−Contact SAMSON in case of different stor-
age conditions or longer storage times.
We recommend regularly checking the elec-
tric actuator and the prevailing storage con-
ditions during long storage periods.
Storage instructions
−Protect the electric actuator against exter-
nalinuences(e.g.impact).
−Protect the electric actuator against mois-
ture and dirt.
−Make sure that the ambient air is free of
acids or other corrosive media.
−Observe the permissible storage tem-
peraturefrom–20to+70°C.
−Do not place any objects on the electric
actuator.
