.....Warning............................................................................................................................

Failure to heed this warning can lead to death, serious bodily harm or considerable material damage.Pay attention to moving parts during assembly and adjustment. There is a danger of injury and considerable material damage.The persons responsible for system safety must therefore ensure that - only qualified persons are entrusted with work on this device,- these persons have read and understood the enclosed operating instructions and product

information. (We recommend our customers to have this confirmed in writing by the assembly personnel),

- the operating instructions are available at all times and the appropriate persons are obliged to observe these consistently at all times in their work (before work according to these operating instructions is commenced, any existing supplementary instructions and documents about valves and actuators should be attached to these instructions),

- proper use of tools, measuring equipment and if necessary the use of personal safety equipment is observed for the correlative work,

- work on this device or in its vicinity is prohibited to unqualified persons.Qualified personnel are persons familiar with the assembly, maintenance and operation of the product in possession of the necessary qualification for their task, e.g. - training or instruction or authorisation to switch on and off, enable, earth and mark circuits

according to safety standards,- training or instruction according to the safety standards in care and use of appropriate

safety equipment,- training in first aid.

1.0 Technical description1.1 Field of application These thrust drives operate actuators which require a linear positioning movement of 4 - 35 mm and a positioning force of 1,2 kN and 2,2 kN e.g. - control valves,- shutoff valves,The actuators have a type approval and are suitable to operate in heating systems with a safety function for water and steam. The actuator has a safety function "fail safe" and is able to close a valve with spring force when the electric supply is cut off. The safety function can be induced from for e.g. a safety temperature-limiting device.The fail safe direction can also work in the other direction -function valve opens.The fail safe direction of the actuator has to be defined for the application and can not be altered.

ATTENTION ! - Only assemble and operate this device when qualified personnel has previously

ensured that suitable power supplies are used which ensure that no dangerous voltages can get into the device in normal operation or in the event of a fault in the system or parts of the system.

1.2 Design The thrust drives are designed for maximum thrust force. The electrical components and the gear are underneath the hood. This protects them against - possibly damaging operating conditions,- possibly damaging ambient conditions,- humidity,- dust.All components are easily accessible after removing the hood.The basic equipment includes - 2 way-dependent switches ("S1" and "S2") and a distance-dependent switch ("S3").

They switch off the motor, when the end travel positions are reached.The following can be installed additionally - 1 or 2 distance-dependent switches ("S3" and "S4"). They limit the end positions or report

intermediate and end positions and are mounted on the switching and display device,- 1 or 2 potentiometers. These are mounted on the switching and display device,- 1 positioning electronics "PE10" (electronic position controller) for analogue control

0 (2) - 10 V or 0 (4) - 20 mA.1.3 Method of functioning FR2.1 / FR2.2The cam-rod is moved in or out by means of reversible synchronous motor, gearbox and connection lever. Because its construction is that of a permanent magnet, the synchronous motor possesses a locking moment even when not under power, which together with the gearbox is so great that the cam-rod of the drive can be stopped perfectly in any position without any measurable post-actuation movement. Should the power be cut off, clutch (pos. 2) is disengaged by the built-in spring washers, thus disconnecting the motor and a part of the gearbox, and the cam-rod is moved into the closure position by spring power. 2 screw pressure springs act as closure springs. A centrifugal brake (pos. 18) is fitted to the moving part of the gearbox to prevent any delay of the closing action in the event of power failure. This has the appropriate dimensions to ensure the necessary closure time on the one hand, and not to present an obstacle to the operation of the motor on the other. The port (pos. 15) in the shape of a slot in the two connection levers (pos. 16) between the gearbox and the cam-rod (see drawing) enables fast and easy setting of the path switch in the direction of closure. When properly adjusted, the closing pressure is generated by the two closure springs even when the motor is running (see the instructions for assembly and adjustment)

2.0 Assembly2.1 Assembly conditions and mounting positionThe mounting position of the thrust drive must be chosen so that - the drive is easily accessible,- there is enough space to remove the hood or to carry out adjustment work,- the thrust drive is protected against extreme heat radiation,- the ambient temperature is not more than + 50°C.Outdoors the thrust drive must be protected by an additional cover against - rain,- direct exposure to sunlight,- strong draughts,- exposure to dust.Any installation position is possible but not hanging downwards. In an installation position with a horizontally positioned thrust rod, the thrust drive is mounted so that the two lantern rods are above each other in the vertical plane.

Fig. 2.1: Assembly of the drive with rod lantern with horizontally positioned thrust rod2.2 Operating the thrust drive manuallyThe electric actuators FR2 can also be manually operatedTo do this, the push buttons for open and closed have to be pressed which are placed on the bottom side of the actuator top part.This only works with the electric supply being available in the actuator. This is not possible when no electric supply is present, not being a mechanical device (conforms to DIN 32730)2.3 Assembly of the thrust drive with a valveBefore assembling, check whether - the technical specifications of the thrust drive match the application conditions,- the valve is complete (tie-bar on the drive or on the valve),- the thread of the valve spindle matches that of the insert of the thrust drive,- the thrust drive is complete with tie-bar or lantern pillars and coupling components for

assembly with the valve provided,- any accessories required are already installed in the drive,- the operating voltage to be connected matches that of the drive,- the specifications on the type plate match those of the motor, - the set or still to be set stroke of the drive matches that of the valve. - ground the actuator and connect the voltage as follows, see terminal connection in the

hood;be especially careful at this, regard point 3.0 of this Operating and Installation Instruction.

0040505000 4298


- When properly connected, magnet 1 is on, engages clutch 2 and thus enables manual adjustment of the drive.

- Move in cam-rod (pos. 4) by (pos. 2) mm using the electrical manual adjustment.- turn the counternut onto the valve spindle up to the end of the thread,- loosen and unscrew both hexagon socket screws (pos. 66) with which the safety plate

(pos. 61) is screwed on,- place the safety plate (pos. 61) over the valve spindle,- Place the actuating drive fully on the valve and screw the threaded socket (pos. 5) on the

valve rod until the columns lie on the crossbar T.- Attach the columns to the crossbar with hexagon nuts (pos. 6).- Fit the threaded socket (pos. 5) on the valve rod with hexagon nut (pos. 7).

3.0 Electrical connection and safety regulations

Failure to heed this warning can lead to death, serious bodily harm or considerable material damages!Read the safety information on page 3 of these instructions!- Only make the mains connection with the power supply switched off! Secure against

accidental switching on!- The DIN/VDE regulations and the provisions of the local energy supply company must be

observed for installation and connection of electrical lines! - Check the conformity of the mains connection voltage and the mains frequency with the

specifications on the type plate of the thrust drive and the type plate of the drive motor. - The line cross-section must always be designed according to the respective power

consumption of the thrust drive and the necessary line length.

- Minimum cross-section of the line for this thrust drive type: 1 mm². - Mains fuse, system side: max. 6 A.- Mains disconnection, system side: to disconnect and cut off voltage from the power line to

the drive for maintenance and adjustment work, an appropriate disconnecting device must be used which ensures all-pole disconnection (except the earth line) when switching off. This disconnect device must be lockable in the off state and secured against unintentional switching on.

ATTENTION ! - Mains connection and commissioning of this thrust drive require special

knowledge of the erection of power plants (DIN VDE 0100), knowledge of accident prevention and special commissioning conditions of this thrust drive. This work may only be performed by qualified personnel.

NOTE ! - Too small line cross-sections are frequently the cause of alleged "operating

faults"!

0040505000 4298


3.1 Removing the hood Cut off power from the supply line first for maintenance and adjustment work!- Unscrew the cap nut,- remove the sealing ring,- hold the hood with both hands and pull off whilst turning slightly. 3.2 Make the electrical connection The circuit diagram stuck in the hood applies basically. - remove the sealing plate in the existing cable gland,- push the supply line through the cable gland until there is a long enough length of line to

the corresponding terminals,- strip off the cable sheath approx. 1 cm above the cable gland,- strip off the individual wires approx. 5 mm from the end,- push the end sleeves onto the stripped end of stranded wires and crimp,- lay the cables in the drive and fix them so that they are protected from moving or rotating

parts and are not damaged when removing or replacing the hood.3.3 Connection example- Operation with single-phase AC (three-position control),- end cut off: in-/outmoving thrust rod way-dependent via switch S1 and S2.

Fig. 3.3: Circuit DiagramConnect the drive as follows:- Connect the protective conductor of the connecting lead (green/yellow wire) to the PE

conductor provided,- connect neutral conductor N of the connecting lead to terminal N,- connect pulse line for outmoving thrust rod to terminal 3,- connect pulse line for unmoving thrust rod to terminal 2,- connect conductor L1 (permanent power) to terminal 40.Instead of bridging 40-41, a safety temperature-limiting device (STB) ore a safety pressure-limiting device (SDB) can be connected.

0040505000 4298


3.3.1 Do a trial run with the drive

- Controlling the drive with three-position controllers, neutral wire N to terminal Nconstant phase L1 to terminal 40Trigger cable Y2 to terminal 3 -> thrust rod drives out of the drive, Trigger cable Y1 to terminal 2 -> thrust rod drives into the drive,

- actuate the switching rollers of the switches with an insulated screwdriver and check whether the respective switches really switch off the motor, for outmoving thrust rod -> switch S1, for inmoving thrust rod -> switch S2.

3.4 To adjust the path limit switch S1 (in the direction of closure) = cam-rod in outwards motion (mains power must be connected)- Move the cam-rod approx. 10 mm inwards using the electrical manual adjustment- Switch off the power to the appliance (simulate power failure) and move the drive into the

closed position using the spring washers. Adjust the stroke indicator ring (pos. 10).- Using a screwdriver (3 mm width), turn the cam (pos. 9) until the switch diagonal of the

cam touches the switch roll of the switch, but without actuating it. Note the turn and switch direction of the cam. Hold drive wheel (pos. 11) when adjusting the cam.

Remark:Because the cam-rod is already in the closed position, when moving under power to the limit position the gearbox turns until the switch above the cam diagonal is actuated and stops the motor. During this movement of the gearbox, the bolt (pos. 15) moves approx. 1 to 1,5 mm downwards in the slot in the connection lever (pos. 16). This guarantees that the full closure power of the spring washers comes to bear and that no undue care is necessary when adjusting the path limit switch.

ATTENTION ! The thrust drive may only be operated without the hood briefly during trial running or for unavoidable adjustment work on electrical options such as potentiometers, distance switches or positioning electronics. During this activity you have access to dangerous voltage-bearing, bare, moving and rotating parts. Improper or careless execution of the adjustment work can lead to death, serious bodily harm or considerable material damage. Only qualified personnel (see page 4) may perform these activities. Operation of the thrust drive without the hood for any other purpose than the one described above is prohibited.

0040505000 4298


3.5 Adjusting the path limit switch S2 in the direction of opening= cam-rod in outwards motion (mains power must be connected)- Using electrical manual adjustment, move the cam-rod inwards until the clutch 2 no longer

turns but makes pendulum-like movements from left to right: this ensures that the maximum opening position of the valve has been reached.

- Using a screwdriver (3 mm width), turn the cam 13 until the switch diagonal of the cam actuates the switch and the roll of the switch has reached the highest point of the diagonal (outer diameter of the cam). Do not slacken the backing nut 17!

Adjust stroke indicator ring (pos. 14). Observe the turn and switch direction of the cam.

3.6 Adjusting the potentiometers (Drive without mains power and in the closed position)- Slacken both attachment screws (pos. 20) of the potentiometer assembly plate (pos. 21),

set the required stroke reading the scale, and re-tighten the attachment screws (pos. 20). The stroke scale is relative to the centre of the screwhead.

- Turn the slotted potentiometer shaft (pos. 22) to the appropriate mechanical turn angle limit using a screwdriver; the built in slide between the potentiometer shaft and the plastic pinion. (Note the turning direction of the potentiometer).

- Switch on the mains and move the drive into the opening direction using the electrical manual adjustment (pos. 23), i.e. to the switching point of the limit switch. Using a measuring device (Ohmmeter), observe the movement of the potentiometer and check that the entire turning angle of the potentiometer is covered.

If the turning angle of the potentiometer is either too great or too small an appropriate adjustment will have to be made to the stroke setting, as specified in items 1.Turning angle too great = stroke setting too small - set stroke higher Turning angle too small = stroke setting too great - set stroke lower.

ATTENTION ! - The switch cams are secured against twisting with the aid of nose disks inserted

in the slit of the camshaft. This does not, however, prevent a certain amount play resulting from dimensional tolerances. This means that when adjusting a switch cam the neighbouring switch cam can also be turned by 1° to 2°. It is therefore recommended, when making precision adjustment of the switch cams, to start with S1 and continue with S2 through to S4, holding the already adjusted cam in place with a second screwdriver.

ATTENTION ! - The slight overreaching of the switch point when adjusting the switch cam

ensures that the motor is stopped just before the maximum valve opening position is reached. It is essential to make sure that the motor is switched off electrically in the opening position via the path limit switch and is not stopped mechanically by the valve. This could damage the gearbox later.

0040505000 4298


4.0 Positioning electronics (setting regulator for actuating drives)

The positioning electronics serve to control, regulate and position setting elements such as thrust, swivel and rotary drives. Inside the positioning electronics a window discriminator (TCA 965) operates as a three-point regulator. The regulator value (current value) and the guide value (set value) in the range of 0-10V DC or 0-20 mA are compared, and in the event of a deviation a value is generated to control the setting element. This continues until the set and current values are identical. A potentiometer of 1000 Ohm is required for the current value (return). This return potentiometer is either directly coupled with the movement of the drive or via a switching and indicating device in the drive which must be built-in.The sensitivity (window width or dead range) is formed by a voltage separator and is 165 mV or 0.33 mA. This sensitivity can be adjusted by re-dimensioning the resistor R7. Lower resistance = smaller window, greater resistance = larger window.The inlet of the positioning electronics is optional. It can be controlled either in the range of 0-10V or 0-20 mA without switching or re-soldering of resistors. Voltage control takes place at terminal 57 (negative pole) and terminal 56 (positive pole). Milliampere control takes place at terminal 57 (negative pole) and terminal 59 (positive pole). The proportional permanent residual voltage standing wave ratio at the input should not exceed 20% of the target value. Induced peaks of voltage, which do occur now and again, are largely taken care of by appropriate measures at the inlet. To prevent inducing of the setpoint as far as possible, this must be fed in a separate line with a tinned copper screening mesh. The line screen must be connected to the housing earth point by appropriate glands. The positioning electronics can be used in sequential operation. The lowest sequential range is 2 V or 4 mA. The setting is done at the trim potentiometers "A" and "B" (basic setting via 1000 Ohm potentiometer). The sequence may fall anywhere within the range 0-10V or 4-20 mA. The upper sequence mark is set with potentiometer "A", and the lower mark with potentiometer "B". If the upper sequence mark is below the maximum value of 10 V or 20 mA, the upper sequence mark must be set first at potentiometer "A" and then the lower sequence mark at potentiometer "B". The reverse setting (the other way round) is performed by turning the reversing plug (see point 4.10) through 180°. The current value (signal) can be received either in volts or milliampere. The signal at terminal 58 (negative pole) and terminal 60 (positive pole) reports milliampere. The signal at terminal 58 (negative pole) and terminal 61 (positive pole) reports volts. The signal can be taken either way, i.e. the value of output corresponds to that of input:E.g. Input = 4-20 mA

output = 4-20 mA or 2-10VIn the sequence range:E.g. Input = 4-8V

output = 4-8V or 8-16 mAThe tolerance of the return signal in comparison with the input is max. approx. 200 mV or 0.4 mA. The signal is not galvanically separated from the input.The built-in light diodes "LED" serve for better adjustment of the limit points, particularly in sequential operation. The light diodes are connected to allow the red diode to be on when the drive is stationary or when no setting value is generated. The green diode comes on when the drive is running or when a setting value is generated.

4.1 Instructions for assembly and adjustment with positioning electronics

4.2 Assembly- Earth the appliance.- Open terminals 51 and 53 on the electronic board and remove the violet and brown wires

from the terminal.- Connect as follows, see also the circuit diagrams in the hood:

neutral wire N to terminal Nconstant phase L to terminal 40

- When properly connected, magnet (pos. 1) is on, engages clutch (pos. 2) and thus enables manual adjustment of the drive.

- Move in cam-rod (pos. 4) using the electrical manual adjustment until switch "S1" switches back (WE-limit position switch for cam-rod in outwards motion).

- Place the actuating drive fully on the valve and screw the threaded socket 5 on the valve rod until the columns lie on the crossbar T.

- Attach the columns to the crossbar with hexagon nuts (pos. 6).- Fit the threaded socket 5 on the valve rod with hexagon nut (pos. 7).

ATTENTION ! (direction of closure = drive cam-rod in outwards motion)- Observe the safety information (see page 3). - Observe the assembly instructions according to point 2.0 to 2.2.

NOTE ! - On delivery the switches "S1" and "S2" are set to the stroke specified on order.i

0040505000 4298


4.3 Setting and adjusting the path limit switch S1 in the direction of closure

= cam-rod in outwards motion (mains must be connected, see point 4.2).- Move the cam-rod inwards by approx. 10 mm using the electrical manual adjustment. - Switch off the power to the appliance (simulate power failure) and move the drive into the

closed position using the spring washers. Adjust the stroke indicator ring 20.- Using a screwdriver (3 mm width), turn the cam (pos. 9) until the switch diagonal of the

cam touches the switch roll of the switch, but without actuating it. Note the turn and switch direction of the cam. Hold drive wheel (pos. 11) when adjusting the cam.

4.4 Adjusting the path limit switch S2 in the direction of opening = cam-rod in outwards motion (mains power must be connected, see point 4.2)- Using electrical manual adjustment, move the cam-rod inwards until the clutch (pos. 2) no

longer turns but makes pendulum-like movements from left to right; this ensures that the maximum opening position of the valve has been reached.

- Using a screwdriver (3 mm width), turn the cam (pos. 13) until the switch diagonal of the cam actuates the switch and the roll of the switch has reached the highest point of the diagonal (outer diameter of the cam). Do not slacken the backing nut (pos. 17)!

NOTE ! - Because the cam-rod is already in the closed position, when moving under

power to the limit position the gearbox turns until the switch above the cam diagonal is actuated and stops the motor. During this movement of the gearbox, the bolt (pos. 15) moves approx. 1 to 1,5 mm downwards in the slot in the connection lever (pos. 16). This guarantees that the full closure power of the spring washers comes to bear and that no undue care is necessary when adjusting the path limit switch.

NOTE ! The switch cams are secured against twisting with the aid of nose washers inserted in the slit of the camshaft. This does not, however, prevent a certain amount play resulting from dimensional tolerances. This means that when adjusting a switch cam the neighbouring switch cam can also be turned by 1° to 2°. It is therefore recommended, when making precision adjustment of the switch cams, to start with S1 and continue with S2 through to S4, holding the already adjusted cam in place with a second screwdriver. Adjust stroke indicator ring (pos. 14). Observe the turn and switch direction of the cam.

set the required stroke reading the scale, and re-tighten the attachment screws (pos. 20). The stroke scale is relative to the centre of the screwhead.

- Turn the slotted potentiometer shaft (pos. 22) to the appropriate mechanical turn angle limit using a screwdriver; the built- in slide between the potentiometer shaft and the plastic pinion. (Note the turning direction of the potentiometer).

- Switch on the mains and move the drive into the opening direction using the electrical manual adjustment (pos. 23),i.e. to the switching point of the limit switch. Using a measuring device (Ohmmeter), observe the movement of the potentiometer and check that the entire turning angle of the potentiometer is covered.

If the turning angle of the potentiometer is either too great or too small an appropriate adjustment will have to be made to the stroke setting.Turning angle too great = stroke setting too small - set stroke higher Turning angle too small = stroke setting too great - set stroke lower.4.6 Connecting the positioning electronics- Disconnect the appliance from the mains.- Reconnect the wires specified in item 4.2. Connect the violet wire to terminal 51 and the

brown wire to terminal 53 on the electronic board.- Connect the control voltage power line fed in a separate line to the electronic board. With

control voltage connect the negative pole to terminal 57 and the positive pole to terminal 56, with control current (mA) connect the negative pole to terminal 57 and the positive pole to terminal 59.

4.7 Give control voltage-current to driveCheck the control voltage-current with a measuring device.4.8 Switch on the power (operating voltage) to the drive4.9 Test the driveThe drive is set at the factory to the specified range and stroke.- Check whether the respective limit position switches "S1" and "S2" actually switch off the

motor. (Check the direction of rotation). Switch "S1" (pos. 8) for cam-rod moving outwards, switch "S2" (pos. 12) for cam-rod moving inwards

- The electronics are set to the appropriate ordered value.

4.10 Make any necessary adjustments with the trim potentiometers "A" and "B"

- Potentiometer "A" for the upper target value mark.- Potentiometer "B" for the lower target value mark.- If the drive has been moved to the limit position, the built-in red diode must be on unless

the drive is to be switched off via switches "S1" and "S2".- Adjust the respective potentiometer "A" or "B", if necessary, until the red LED lights up and

the green LED is off.- If the drive is to be reversed against the target value switch off the operating power, pull

out the reversing plug, (see point 4.0) turn it through 180° and stick it back in. Switch the power back on. Repeat if necessary.

4.11 Fit the hood and lock it with the cap nut and sealing washerMake sure it is tight and sealed.4.12 Adjusting the target value input.- If you wish to switch from voltage control to current control, relocate the connection line

positive pole to the appropriate terminal.4.13 Adjusting the sequence ranges- Example 4-20 mA. Using the electrical manual adjustment, move the drive to the

appropriate limit position in which it should be at 4 mA, until the appropriate switch actuates.

- Hold down the appropriate key.- Power the electronics with 4 mA.- Turn potentiometer "B" clockwise until the red LED lights up and the green LED goes out.- Test the drive.4.14 Sequence range 6-12 mA- Using the electrical manual adjustment, move the drive to the appropriate limit position in

which it should be at 12 mA, until the appropriate limit position switch actuates.- Hold down the appropriate key.- Power the electronics with 12 mA at terminal 57, negative pole and terminal 59.- Turn potentiometer "B" clockwise until the red LED lights up and the green LED goes out

(only Poti "B").- Move the drive into the other limit position in which it should be at 6 mA, until the limit

position switch actuates.- Power the electronics with 6 mA at terminal 57, negative pole and terminal 59.- Turn potentiometer "A" clockwise until the red LED lights up and the green LED goes out.- Test the drive. Make minor adjustments to potentiometers "A" and "B" if necessary.

4.15 FeedbackThe feedback signal - need not be set, - is not electrically isolated from the input. The actual value (feedback) is tapped either as - voltage DC 0 (2) - 10 V at the terminals 58 (minus pole) and 61 (plus pole), - current DC 0 (4) - 20 mA at the terminals 58 (minus pole) and 60 (plus pole). Feedback is in the same direction, i.e. an increasing input signal (setpoint) causes an increasing feedback signal. The size of the output signal always corresponds to the value of the input signal, E.g. Input = 4-20 mA output = 4-20 mA or 2-10VIn the sequence range:E.g. Input = 4-8V output = 4-8V or 8-16 mAThe tolerance of the return signal in comparison with the input is max. approx. 200 mV or 0,4 mA.
