1.1 Notes on possible severe personal injury
DANGER!
Risk of electric shock. Î Beforeconnectingwiring,performinganyworkonthedeviceoropeningthede-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 open the back housing cover.
The electric actuators with process controllers are protected against dripping water fall-ingatanangle(IP 42).
Î Avoid contact with spray water or water jets.
The switching output L' is live after the power supply has been connected. Î Do not touch the switching output L'.
Risk of bursting in pressure equipment.Control valves and pipelines are pressure equipment. Improper opening can lead to valve components bursting.

Design and principle of operation
3 Design and principle of oper-ation
TheTROVIS 5757-7ElectricActuatorwithProcess Controller is a combination of a lin-ear actuator and an integrated digital con-troller. The combination is especially de-signed for heating applications as well as for fixedsetpointcontrolofheatingsystemsinsmalltomedium-sizedbuildings.Itispartic-ularly suitable for mounting to SAMSON Types 3222,3222 N,2488and3267Valves(DN 15to25)aswellastospecialversionsofType 3226andType 3260Valves.Thedigitalcontrollerisconnectedtoaflowsensor on the input side, which can be op-tionallyupgradedbyareturnflow,outdoororroomsensor.InadditiontothePt 1000input, the digital controller has a potentiome-terinput(1000to1100 Ωor1000to2000 Ω)tomeasuretheflowtemperature.Thisinputinfluencestheheatingcharacteris-tic in the case of outdoor-temperature-con-trolled control and the room temperature set pointinthecaseoffixedsetpointcontrolwithroomtemperatureinfluence.Theheat-ing characteristic and set point can be changedovertheTROVIS-VIEWconfigura-tion software.The output signal of the integrated digital controller acts over the positioner on the syn-chronous motor of the actuator and is trans-ferred over the connected gear to the actua-tor stem (3) and used as the positioning force.
The motor is switched off by torque-depen-dent 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) fol-lows the motion of the return spring.

Measures for preparation
4 Measures for preparationAfter 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 SAMSON and the forwarding agent (re-fer 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-nalinfluences(e.g.impact).
− Protect the electric actuator against mois-ture and dirt.
− Observe the permissible transportation temperatureof–20to+70 °C.
4.2.2 LiftingDue 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 long storage periods.
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-nalinfluences(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.

6 OperationImmediately after completing mounting and start-up, the valve with electric actuator is ready for use.
6.1 Manually changing the stem position
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 automati-cally corrected.
The stem position is changed at the hand-wheel:
Î Switch off the power supply. Î Turn clockwise to extend the actuator stem(approx.4turnsfor1 mmtravel).
Î Turn counterclockwise to retract the actu-atorstem(approx.4turnsfor1 mmtrav-el).

Servicing
7 Servicing
The electric actuator with process controller was checked by SAMSON before it left the factory. − The product warranty becomes void if service or repair work not described in these instructions is performed without prior agreement by SAMSON's After-sales Service. −Only use original spare parts by SAMSON, which comply with the original specifications.
7.1 Preparation for return ship-ment
Defective electric actuators can be returned to SAMSON for repair.Proceed as follows to return valves to SAMSON:1. Put the control valve out of operation and
remove it from the pipeline. See associat-ed valve documentation.
2. Remove the electric actuator from the valve.Seesection 9.2.
3. Send the electric actuator to your nearest SAMSON subsidiary. SAMSON subsid-iaries are listed on our website at u www.samson.de>Contact.
8 Malfunctions Î Troubleshooting(seeTable 1).
Contact SAMSON's After-sales Service de-partment for malfunctions not listed in the ta-ble.
8.1 Emergency actionThe plant operator is responsible for emer-gency action to be taken in the plant.
Emergency action in the event of valve fail-ure is described in the associated valve doc-umentation.
9 Decommissioning and disas-sembly
Risk of electric shock. − Before performing any work on the device and before opening the device, disconnect the power supply and protect it against un-intentional reconnection. −Only use power interruption devices that are protected against unintentional recon-nection of the power supply.

Decommissioning and disassembly
Risk of bursting in control valve compo-nents due to incorrect opening. − Before starting any work on the control valve, depressurize all plant sections con-cerned and the valve. − Drain the process medium from all the plant sections concerned and from the valve. −Wear recommended personal protective equipment. See associated valve documen-tation.
9.1 DecommissioningTo decommission the electric actuator for maintenance work or disassembly, proceed as follows:1. Close the shut-off valves upstream and
downstream of the control valve to stop theprocessmediumfromflowingthrough the valve.
2. Completely drain the pipelines and valve.
3. Disconnect and lock the power supply.4. If necessary, allow the pipeline and valve
components to cool down.5. Remove the valve from the pipeline. See
associated valve documentation.
