1 Safety Information
This safety information must be studied and applied by all persons involved with the operation, maintenance or the repair of the actuator. The actuator represents the latest in technology and safety. The actuator can, however, constitute a hazard if used incorrectly by untrained personnel or if not used as specified. This may result in:
� potential injury;� damage to the machine and other equipment of the client;� the efficient operation of the plant being impaired.
Conversions or changes to the actuator may not be carried out by the client. Maintenance and service work may only be carried out by trained personnel. When connecting and disconnecting electrical equipment, the valid VDE and EVU regulations must be observed. Electrical protection measures (ground resistance, etc.) must be checked. During work on the actuator or on equipment connected to it, the actuator must be isolated.It must be ensured by suitable measures that inadvertent activation of the drive is prevented.The drives are equipped with a thermal protector in the motor winding and two torque switches (Z3 and OA are not equipped with a torque switch). This protection is provided on floating terminals and must be connected in order to protect the drive and the flange-mounted fittings.
2 Description of Drives
2.1 Correct Use
Deufra actuators and modulating actuators are designed for installation on valves such as butterfly valves, dampers, louvers, globe valves, pinch valves, gatevalves and ball valves. They provide a save remote operation of valves for regulating or stopping media carried in pipes. The actuator and modulating actuator has the task of moving the mechanically limited valve within the specified travel into the end positions or into a specified intermediate position.The actuator may not be used on devices or equipment where staff could be injured by moveable parts without proper guards being in place. Training and safety instructions must be implemented. The equipment is not suitable for use with doors, gates or transport equipment used for persons.
2.2 Equipment Characteristics
DEUFRA actuators and modulating actuators consist of a functional unit including an electric motor, check-back equipment and one or more connected gear systems.
2.2.1 Travel limit
The actuator travel of the equipment depends on the mechanics of the valve and can be o o90 , 360 or several revolutions.
DEUFRA actuators and modulating actuators are equipped with limit switches for the end positions OPEN and CLOSED to limit the actuator travel. These switches can be set anywhere over the entire travel (except type Z3).
DEUFRA Version 010911engl Page - 4 -
-
2.2.2 Mechanical End StopsoIn case of an actuator travel of 90 , the actuator is mechanically and electrically restricted.
oIn case of an actuator travel of over 90 or several revolutions, the actuator is only electrically restricted. In this case the mechanical restriction is suitably provided within the valve.
2.2.3 Torque Switch
Some type of valves (i.e.gate valves) require an exactly defined torque to achieve close shutting. This tripping torque is calculated and determined by the manufacturer of the valves and depends on the operating conditions. Generally, the torque for opening and closing differ. For more details consult the manufacturer of the valves.
DEUFRA actuators and modulating actuators (except type Z3 and OA) contain an opening torque switch and a closing torque switch for torque-controlled switch-off. The tripping torque can be adjusted differently for opening and closing (see also 4.3).Where the actuator is operated as a position actuator, these switches serve as a cutout for the protection of the equipment and valves.
2.2.4 Thermal Protector
The motor of the DEUFRA actuators and modulating actuators contains a bimetal thermal protector in the motor winding. The switch monitors the motor temperature and protects the motor against overheating.
Caution: To maintain the full motor protection and the guarantee, the switch must be integrated into the controls.
2.2.5 Switchroom Heating
Despite or because of the high protection type 67, condensate may be formed in case of temperature fluctuation or humid conditions. The condensate can cause corrosion, functional failure of the check-back system and can damage the motor. Up to 20 mg of water may be generated by each temperature change. As the drives are well sealed, the water does not escape but is gathered.
DEUFRA actuators and modulating actuators with protection class IP67 are supplied with switchroom heating (option for increased-safety drives). The heating prevents the formation of condensate as a result of temperature fluctuations or humid conditions.
Note: In order to maintain the guarantee, the heating must be connected. This can only be done by the client.
2.2.6 Electrical Connections
For the electrical connection of the actuators, industrial terminals in a large-sized switchgroup room are used. All connections of the signal switches, additional equipment and of the motor have been provided as floating contacts on terminals by the manufacturer.
2.2.7 Cable Inlet
Two PG16 or M25 cable glands are available for cable access (except for EEx d).
DEUFRA Version 010911engl Page - 5 -

2.2.8 Motor
2.2.8.1 Single-Phase A.C. Voltage
DEUFRA actuators and modulating actuators can be supplied with a reversible cage motor for operation with a single-phase a.c. current supply (please observe type sign on actuator). The capacitor integrated in the switchroom provides the phase shifting required for generating the rotating field.
2.2.8.2 Three-Phase A.C. Voltage
DEUFRA actuators and modulating actuators can be supplied with a reversible cage motor for operation with a three-phase a.c. current supply (please observe type sign on actuator).
2.2.8.3 D.C. Motor
DEUFRA actuators and modulating actuators can be supplied with a reversible compound motor for operation with a d.c. current supply (please observe type sign on actuator).
2.2.8.4 Operating Modes
DEUFRA actuators and modulating actuators are designed for a S4 intermittent operation according to VDE 0530. After each switching, the motor requires a cooling-off break. The length of the break depends on the time the motor had been switched on. The switch-on time depends on the task for which the actuator was intended. The tasks are divided into Open/Close operation, class III closed-loop control and class II closed-loop control. The different drives have the following switch-on times:
Open/Close operation S4 30% ED 300 c/hClosed-loop control class III S4 50% ED 1200 c/hClosed-loop control class II S4 100 % ED 1800 c/h
2.2.9 Handwheel Operation
DEUFRA actuators and modulating actuators are provided with a handwheel for operation in case of power failure. With the aid of the handwheel, the drive can be moved into any random intermediate position and into the end position. During activation of the handwheel, the switching cams of the travel switch-off system are also moved along. As a result of the movement of the switching cams, the travel setting is maintained.
The actuator therefore does not have to be reset after a manual operation. When designing the controls, the fact that the travel limit may be left and no adjustment using the handwheel may be possible during automatic operation, must be taken into consideration.
Note: In case of the actuators not being isolated, the controls may switch on the motor and move the device back into the electrically triggered end position.The AS100, AS200 and AS400 drives are equipped with a handwheel that is automatically declutched during motor operation. Prior to manual operation, the handwheel must be engaged by turning the clutch lever.
DEUFRA Version 010911engl Page - 6 -
-
The actuators of control class II, types MAS and MBS are equipped with a handwheel that is automatically declutched. For manual activation, this handwheel must be pushed and turned towards the actuator housing with both hands. A switch located behind the handwheel is activated during this process and signals the intervention to the controls. The controls must process the signal and isolate the actuator.
2.2.12 Connection Flange
DEUFRA actuators and modulating actuators are supplied with a connection flange according to ISO. The flange contains 4 threaded bores and a centring ring. Depending on the actuator type, combination flanges with two different ISO drilling patterns are provided. The dimensions comply with the ISO standard and are specified in the brochure or order documentation. Information about the dimensions of the valves is available from the valve manufacturer.
2.2.10 Mechanical Position Indicator
DEUFRA actuators and modulating actuators are equipped with a mechanical position indicator to provide a visual position indication. This can be read off through a window in the switching room cover.
2.2.11 Declutchable Intermediate Gears
Some DEUFRA actuators and modulating actuators are equipped with declutchable intermediate gears (i.e. OA15, OAP, ASP AS50).
oBy moving the clutch lever by 180 (OA15, OAP and ASP) or by pulling out the lever and oturning it by 90 (AS50), the motor is disengaged from the gears. This declutching serves
solely for reducing the force required for manual operation of the handwheel. A combined manual/automatic operation by declutching the motor is not permitted.
Caution: In this case, the motor could get too hot as it is not switched off.

2.2.13 Drive Shaft
The shafts of DEUFRA actuators and modulating actuators are machined according to client specification. Most actuators contain an exchangeable socket and can be adapted to the valve without problem. The available dimensions of the machining and which actuators are supplied with an exchangeable socket are specified in the catalogue. Information about the dimensions of the valve is available from the valve manufacturer.
2.3 Functional Description
DEUFRA actuators and modulating actuators have the task to electrically open or close the valves in accordance with the intended use or to move them into an intermediate position.For this purpose, an electric motor and a power gear for generating a rotary movement and the necessary torque are required.Due to the limited actuator travel, a travel switch-off system must signal the reaching of the end position.The drive has two directions of rotation. One for anti-clockwise and one for clockwise rotation (Open/Closed). To change the direction of rotation, the motor must be switched over. After switching on the motor in the desired direction of rotation, the drive shaft moves into the selected direction. Once the motor is switched off, the drive shaft stops at the reached position. This may be the desired intermediate or the end position. If the motor has stopped and the actuator is not yet in the end position, the motor can be reactivated to run in the same or in the opposite direction (positioning operation). If the drive is in the end position, the motor may only be activated in the opposite direction. Where the actuator locks in an intermediate or in the end position, a torque switch assigned to the direction of rotation is activated. This may mean that the actuator has moved to its end position (torque-triggered switch-off) or that a fault has occurred. Overloading of the drive motor causes considerable heating of the motor. At a motor
otemperature of approx. 120 , the thermal protector of the motor opens a contact. This information signals a fault. In order to fulfil this task and evaluate the signals provided by the actuator, a control provided by the client or a control from the DEUFRA range of accessories is required.The valve includes interlocking connecting elements between the actuator and the valve, transferring the actuator torque and actuator movement to the shaft of the valve.
DEUFRA Version 010911engl Page - 8 -

2.4 Ambient Conditions
DEUFRA actuators and modulating actuators of protection type IP67 may be installed in dry and wet rooms and outside. The motor has been manufactured to insulation class F standard and is suitable for installation in tropical regions.Temperature range -20° to +70°.
� In case of installation in wet areas and areas exposed to strong temperature changes, the integrated protective heating must be connected. Additional anti-corrosion measures are recommended.� In areas with an aggressive environment (i.e.: acid, salt, mineral dust) suitable
protection of the equipment must be agreed with the manufacturer.� In environments exposed to extreme cold or heat, suitable special models must be
ordered from the manufacturer.� Fireplaces, ovens or other heat sources radiate a high volume of energy. This short-
wave radiation can heat the insides of equipment excessively and destroy the components integrated in the actuator despite available cooling ambient air. Under such conditions, a suitable screening of the heat radiation must be provided.� Depending on their type or their resonance with the actuator components, vibrations
may cause damage or accelerate the wear of components. Components subject to wear, such as potentiometers or electronic position indicators, are particularly sensitive. The use in environments subject to vibration must be discussed with the manufacturer of the drive.
3. Installation
3.1 Transportation and Storage
3.1.1 Transportation
DEUFRA actuators and modulating actuators are packed in such a way that no damage can occur during transportation under normal transportation conditions.The actuators can weigh between 5 and 550 kg.It must therefore be observed that suitable lifting gear is used during transportation and installation. The lifting gear may under no circumstances be attached to the handwheel.
3.1.2 Storage
DEUFRA actuators and modulating actuators must be stored in clean and dry rooms and protected against temperature changes or sun radiation. Where storage under these conditions is not possible, the switching-room heating of the drive must be connected with the voltage specified in the order. Also suitable measures against ground moisture, soiling and corrosion must be implemented (i.e. moisture absorbing agents).
3.2 Installation on the valve
3.2.1 Installation Position
DEUFRA actuators and modulating actuators are filled with grease in order to lubricate the gears. The installation position of the equipment is therefore generally immaterial. As the safest installation position, we recommend to position the flange downward towards the centre of the ground.
DEUFRA Version 010911engl Page - 9 -
-
3.2.2 Direct Installation on the valve
For direct installation on the valve, DEUFRA actuators and modulating actuators are equipped with an ISO flange with four internal threads and a shaft seat specified in the order. A centring ring is also supplied for ensuring central installation on the valve. This centring ring also serves to prevent socket of drives from slipping out of the valve. Where no centring ring is used during installation, it must be observed that the design of the valve prevents the socket from slipping out of the valve.
� Remove the protective foil from the drive flange.� Prior to installation check that the dimensions of the actuator correspond with those
of the valve.� Ensure that the actuator and the valve are in the same position (i.e. closed position)
(see also 6).� Place the centring ring the right way up into the provided groove (see fig.).� Grease driveshaft thoroughly with non-corrosive grease.� Push drive onto shaft of valve.� By turning the handwheel, align the threaded holes in the valve with the fastening
bolts.� Insert the fastening bolts into the fastening holes in the valve and tighten bolts.
The length of the bolts depends on the thickness of the valve flange and the depths of the thread in the actuator flange. The quality of the bolts depends on the application and is determined by the valve manufacturer.

Note: The socket used for transferring the actuator movement and the torque and the installation flange are externally positioned as interface to the valve. On these external points, the device cannot be protected against corrosive media. External actuator components must be protected by the client.

3.2.3 Installation with Mounting Frame and Lever
DEUFRA actuators and modulating actuators can be supplied with a mounting frame and an actuating lever for operating the valve via a lever gear system. The place of installation must be selected in such a way that the actuator lever and valve lever are flushly aligned. During operation, no distortion may occur over the entire travel. The actuator transmits considerable forces. It must therefore be observed that no obstacles or persons are in the work area of the overall construction. Where necessary, cages or other suitable guards must be installed on site. The actuator lever is provided with a ball-ended spindle acc. to DIN 71803 or an articulated head acc. to DIN 648 by the manufacturer. The levers are connected by the client. A suitable lever gear system with turnbuckle sleeve and joints is available from DEUFRA as an accessory.
The mounting frame is equipped with four holes for receiving dowel bolts or threaded bolts (sizes are specified on dimensional drawings).
� Drill dowel holes or install threaded bolts in accordance with the dimensions of the mounting holes of the mounting frame.� Align the frame on top of the dowel holes or threaded bolts. � Check that the mounting surface is flush and the mounting frame is completely flush.
Any distortion may cause the frame to be damaged.� Bolt down mounting frame.
3.2.3.1 Lever Installation
The actuating lever is secured to the actuator shaft by a tensioning set. Supplied levers are set to the centre position and the required torque (to be transferred). The tensioning sets vary according to the torque to be transferred. The following applies to all tensioning sets:For changing the setting or dismantling the lever, the tensioning set must first be released (see also sections 3.2.3.2 to 3.2.3.6). Where the lever cannot be moved after correct releasing, it must be loosened, using a mallet. Tap the lever several times in the left and right operating direction.
CAUTION: Never hit the tensioning set or front of the lever. This may cause the lever to break or the tensioning set to be damaged.
After succesful adjustment, the lever tensioning set is re-tightened and the protective cap is replaced. Check that a 5-mm gap exists between the mounting frame and the actuating lever. After tightening, a gap of 0.5 1 mm must still remain (see also 4.5).In case of a new installation, the lever shaft, the bore in the lever and the tensioning set (N2035, N3047 and N3555) must be clean and free from grease. Turn the tensioning set nut anti-clockwise until the tapered surfaces of the internal and external element are no longer prestressed. Insert tensioning set into the bore of the lever from the front and push parts onto shaft. Check that a 5-mm gap exists between the mounting frame and the actuating lever. After tightening, a gap of 0.5 1 mm must still remain. Retighten lever.

3.2.4 Installation with clutch and bracket
Where the dimensions of the valve differ from the ISO standard or in case of special works regulations, an installation with clutch and bracket may be required. These installation components are generally supplied by the manufacturer of the valves.
� First install the bracket according to the manufacturer's instructions and push clutch onto shaft of the valve.� Next install the actuator as described under "Direct Installation on theValve”.� Ensure that all parts are flushly aligned and are not distorted during tightening.� Ensure that the socket contact is supported by the clutch and can not slip out.
3.2.5 Installation and Disassembly of Socket
The socket of the DEUFRA actuators and modulating actuators has generally already been inserted in the drives prior to shipment.In some cases it may be necessary to disassemble or replace these (i.e. ordered machining of shaft was incorrect).Depending on the type, the socket can be turned as follows:
oType with two catches by 180oType with four catches by 90
oOctagonal type by 45
3.2.5.1 Sockets for Actuators Z3 OA, AS, BS
The socket sits loosely in the actuator housing and is not secured by bolts or circlips. The contact can be easily pulled out via the front of the housing. An O-ring for sealing the actuator shaft ensures that parts of the socket are held tightly in the drive flange.
� Remove the centring ring� Where necessary, place a suitable hook behind the socket to pull it out� Ensure that component is not wedged in� When inserting the socket ensure that grease has been applied to it.� The catches must be accurately positioned above the respective recesses.� Ensure that the bore is in the right position� Set the socket from the front in the actuator flange and press this up to the notice in

4 Settings
4.1 Adjusting the Travel Limit Switches
The travel limit switches of DEUFRA actuators and modulating actuators are set by the manufacturer to the "OPEN” and "CLOSED” end position +/- 5% travel. The setting does not guarantee that the desired positions for tight closing or 100% opening are reached once installed on the valve. The final adjustment of the travel limit switch is carried out after installation on the valve. After each installation and disassembly and after the installation of the valve in the machine, the setting must be checked and adjusted, where necessary.The travel is set using coloured cams on the cam block. The adjusting screws are marked with rings that have the same colours as the cams. The cam block turns clockwise during closing and anti-clockwise during opening (viewed from the top of the block). The travel can be finely adjusted over the entire operative range.
Colour assignment of cams:
White Travel limit direction of rotation II, close
Black Travel limit direction of rotation I, open
Beige Additional travel limit direction of rotation II, close
Grey Additional travel limit direction of rotation I, open
� Undo and remove the four screws of the switching room cover.� Position a suitable screwdriver into the
slot of the desired adjusting screw and push down for engaging the internal toothed gear. � In order to reduce the travel in the
"CLOSE" direction, turn adjusting screw clockwise or turn anti-clockwise to increase the travel.� In order to reduce the travel in the
"OPEN" direction, turn adjusting screw anti-clockwise or turn clockwise to increase the travel.� Pull screwdriver out of screw, ensuring
that the screw re-engages or is flush with the top of the cam block.

4.2 Setting the Mechanical Limit StopsoThe mechanical limit stops are set via two stop screws adjustable by +/-2 . The screws
are used to limit the travel during manual operation and may not be used for limiting the travel of the motor operation or for a torque-triggered switch-off. The stop screws may not be used for securing the actuators to on-site machine components or for screwing these to equipment. After each change of the travel setting, the mechanical end stops must be reset. In order to ensure the safe operation of the travel switch, the mechanical stop must
obe set approx. 2 larger than the electrical path. Hexagon socket set screws secured with hexagon nuts are used as stop screws. They are located on the side of the actuator housing (viewed from top through actuator onto actuator shaft).
� Move actuator with handwheel to the travel limit of the position to be adjusted.� Hold the setscrew with a spanner whilst releasing the lock nuts by several turns.� Schrauben Sie den Gewindestift nach rechts bis zum Anschlag in das Gehäuse.� Screw set screw clockwise up to the stop into the housing.� Turn back the setscrew by one turn in anti-clockwise direction.� Tighten lock nut, ensuring that the setscrew does not turn during tightening.

Figure: Limit stops
4.3 Setting of Torque Switch
Actuators Z3 and OA are not equipped with torque switches and can not be retrospectively equipped with these switches.Unless otherwise specified, the torque is set to the maximum actuator torque. The set values are listed under Nm/ÖO for Opening and Nm/SCF for Closing in the bottom third of the type sign. The works setting generally do not have to be changed.
Note: Where settings have to be changed, this should be agreed with the manufacturer of the valve and of the actuator. An incorrect setting can adversely influence the correct functioning of the unit. The valve or actuator may also be damaged.
The torque springs are located underneath the motor in the drive housing. They are guarded by a cover held in place by two hexagon socket screws. The internal spring bolt is held in place by two lateral hexagon socket screws. All screws are accessible from the outside. A brass catch is positioned at the centre of the spring bolt. The springs are pre-tensioned with hexagon nuts secured by lock nuts.
DEUFRA Version 010911engl Page - 18 -

The torque switches are located next to the terminals in the switching room and are activated by a ram.
� Undo hexagon socket screws of cover and remove lid. Undo the four screws of the switching room cover and remove cover.� Ensure that drive motor can not be switched on and that nobody turns the
handwheel.� Undo lateral hexagon socket screws and remove torque unit.� Undo lock nuts of springs (requires narrow spanner).� Change tension of spring according to the spring diagram. The pre-tensioning length
in mm between the catch and the washer of the nut is measured with a sliding calliper. The diagram can be obtained from the actuator manufacturer.� Secure nuts with lock nuts after adjustment and re-install torque unit.� During re-installation, ensure that unit is not incorrectly inserted,� When securing the torque unit check that unit is centred.� With the lateral inside hexagonal screws the position can be set up.� Mount the covers and ensure correct seating of the cover seal and that no cables are
trapped.

4.4 Setting of Mechanical Position Indicator
The mechanical position indicator is pre-set prior to shipment. oThe position indicator is located on the travel limit block and is freely rotatable by 360 .
The unit can be dismantled by tilting the indicator to the side.Due to vibrations during transportation or dismantling during the connection of the actuators, final adjustment can only be carried out at the installation site. The setting is the responsibility of the installation staff or of the person, who opened the unit last. The indicator can easily be set.
� Undo the four screws of the switching room cover and remove cover.� Turn position indicator to the desired
position and close drive.Ensure correct seating of the cover seal and that no cables are trapped

4.5 Setting of the Actuating Lever
As a result of the use of tensioning sets, the actuating lever can be infinitely secured in oany position. The rotation angle of the lever is 90 in relation to the drive shaft. This
rotational movement is transferred to a linear movement with the aid of a connecting rod. The length of the lever can be changed in set increments by displacing the articulated head on the lever (see dimensional drawing in brochure).
� Release the lever (as described in 3.2.3 to 3.2.3.6) and set the desired position.� Observe angle ratios.� Secure lever (as described in 3.2.3 to 3.2.3.6).� Undo articulated head and secure again in desired position.� Observe length ratios between the actuator lever and the valve lever.
oNote: An angle, changing by 90 over the operative travel, is formed between the lever and the connecting rod. As this angle is of considerable importance for the transmission of forces, it may not be randomly reduced or enlarged.
� The permissible angles depend on the required actuating force and the driving torque and must be calculated and determined for each possible application by the designers of the plant.The best possible angle setting at which the highest forces are transmitted is the
ocentre position of +/- 45 pre-set by the manufacturer.� The lever (valve lever) opposite the actuator should have the same length as the
actuator lever. It influences the transmission forces and maximum possible actuating travel of the valve.
� A longer valve lever reduces the force required by the valve and reduces the actuating travel.A shorter valve lever increases the force required by the valve and increases the actuating travel.
� Overloading of the actuators as a result of the selection of incorrect angles or lever lengths must be avoided.

5 Electrical Connection
The actuators and modulating actuators may only be electrically connected once all electrical welding work has been completed and the machine has been earthed.The DEUFRA actuators and modulating actuators are generally supplied with two travel limits, two torque switches (except Z3 and OA), one thermal protector, one heating and one electrical motor. All connections are connected to numbered terminals as floating inputs. The numbering of the terminal corresponds to that of the circuit diagram. In case of any deviations (i.e. differently named terminal schedule), the drive may not be connected. Please clarify the matter with the actuator manufacturer in this case.The actuator must be connected in dry weather. Where this is not possible, suitable measures for preventing moisture from entering the actuator/drive must be implemented.
� Undo the four screws from the switching room cover and remove cover.� Check that the diameter of the cable sheath selected for the cable gland is large
enough to ensure a good seal around the cable.� Push cable through cable gland into the connection room of the drive.� Ensure that the cables are inserted from the bottom and that a loop exists.� Insulate the cables and attach as shown in wiring diagrams.� Take care not to trap the insulation.� Check the correct seat and contact of the cores.� Secure connection cables along the wall of the building and fix with cable ties.� Ensure that no moveable parts are trapped in the actuator.
5.1 Cable Entry Points
5.1.1 Protection Type IP67
The control and motor cable enter the connection room of the drive via a PG16 or M25 cable gland.
5.1.2 Protection Type Eex de
Explosion-protected actuators of protection type Eex de IIC T4-5 contain two separate connection rooms. The terminal room of the motor contains three motor terminals and the two terminals for the thermal protector. The control switch terminal room contains the connections for the travel limit and torque switch and the accessories. In each case, the cables enter the terminal room via a PG16 or M25 cable gland provided for each terminal room.
5.1.3 Protection Type EEx d
The actuators and modulating actuators of protection type EEx d IIC T4-5 contain a terminal room for the connection of the motor and the control switch. Two ¾” NPT threaded holes, sealed with caps, are provided as cable entries. Cable glands are not supplied as standard.
DEUFRA Version 010911engl Page - 21 -

5.2 Terminals
The actuators and modulating actuators are connected via industrial terminals in the generously dimensioned switchgroup room.The terminals of the standard equipment can accommodate cables with cross sections of
2between 0.2 to 4 mm , whilst the terminals of the accessory can accommodate cables 2with cross sections of between 0.2 to 2.5 mm .
5.3 Control Switch
The DEUFRA actuators and modulating actuators are equipped with micro switches for signalling the actuator conditions. These switches do, however, have different characteristics, depending on their function.
� Travel limits are triggered via the cams of the cam block. The self-locking nature of the gears ensures that the switch position is maintained and that the control signal is continuously applied.� Torque switches are activated via an external toothed ring of a planet gear, a
plunger for activating the switch and two springs, based on the torque balance principle. This design allows a precise torque control. As the planet gears are not self-locking, the springs push back the plunger into his initial position to relieve the entire system once the motor has been switched off. The signal is not continuously applied.� The thermal protector is a bimetal switch integrated in the motor winding. The
oswitch opens at approx. 120 C and returns to its initial position once cooled off. The signal is not continuously applied.
Due to the different functions of the switches, the switches may not be connected in series. It is also not permitted to connect the control switches of several actuators to one signal.Depending on the type, the DEUFRA actuators and modulating actuators provide an output of between 0.03 and 0.5 kW. The load of the switching contacts is only inductive. In the single-phase a.c. type, a capacitor is used for phase shifting which charges itself to the peak value of the connection voltage.As the switches are subject to wear and tear and switching capacity is limited, we recommend not to use these for direct motor switch-off (exception Z3).The switches of Ex drives may, according to explosion prevention regulations, generally not be used for motor switch-off.

5.4 Motor
The motor is reversible. It can be operated in clockwise or anti-clockwise direction. Reversing controls are normally required for this. For the operation of the motor three terminals for external connection are used in case of a three-phase and a.c. supply and five terminals in case of a d.c. supply.
� Single-phase a.c. currentNeutral (N) is always connected to the same terminal as shown in the circuit diagram. The direction of rotation is changed by changing the phase of the other two terminals.� Three-phase current
As shown in the circuit diagram, the three phases are connected in the sequence U, V, W for one direction of rotation. The direction of rotation is changed by changing phases U and V.� Gleichstrom
D.C. currentAs shown in the circuit diagram, d.c. voltage is connected to the shunt winding. The direction of rotation is changed by reversing the armature voltage.
Note: It must be observed that the actuating travel is electrically restricted. Upon reaching the end position, all connections must be isolated via the contactors. The delay time between the switching of the travel limit and the release of the contactor must not exceed 50 ms.The suitability of the control relay for switching the motor must be discussed with the relay manufacturer for the AC3 operation. In case of a single-phase a.c. current motor equipped with a capacitor, the capacitor is discharged at the time of activation and reacts like in the case of a short circuit. This results in extremely high starting currents. We recommend the use of miniature contactors with a contact rating of 16 A.
6 Commissioning
Generally, commissioning is not carried out at the time of installation and connection. In many cases, these operations are handled by different contractors. As it is not apparent whether any changes have been carried out in the mean time, special attention must be paid to the commissioning.
� Check once again all connections and settings.� Check that the drive can be easily moved with the handwheel and does not lock.� Check the correct functioning of the travel limit and the torque switch and that the
signal arrives at the controls.� Check that the controls react correctly to the received signal.� Check for obvious damage.� Check for correct direction of rotation by moving the actuator into the centre position
with the handwheel and briefly switching on the motor via the controls.
In case of any faults or incorrect function being detected during these tests, the actuator may not be started before any problems have been resolved.
� Fully open and fully close the device with the controls.

7 Maintenance
DEUFRA actuators and modulating actuators are maintenance-free. They do not contain any components that need to be replaced in set maintenance intervals.In case of adverse ambient conditions, such as moist rooms or outside use, external parts may be subject to corrosion or the protective paint layer may be damaged. In this case, a regular visual inspection, repair of any damage, greasing of endangered parts and repainting may be required.In case of a failure of the unit or a defect, the drive should be send to the nearest Customer Service point.
