1 ACTUATORS WITH INTEGRAL CONTROL 1

2 Valve actuators for multiple applications Wherever material flows through pipelines in liquid, gas or powder form, several kinds of valves are used to shut off or to regulate the rate of flow or pressure. For reliable remote operation of these valves, whether they be globe, gate, ball or butterfly valves or dampers, DREHMO electromechanical actuators have been employed successfully the world over for several decades. DREHMO actuators are used in oil and gas fields, pipelines, tankfarms, oil and gas terminals, power generation, chemical and petrochemical process industries as well as in water works and waste water treatment plants. Actuators have to move the valve to a mechanically definded final position Water 2

3 or to intermediate positions, avoiding excessive torque during actuator travel and in the final positions so as not to overload the valve. Special devices therefore ensure that the actuator motor is switched off when it reaches a certain position, angle of rotation or torque. Special variants include partturn actuators and thrust actuators, which transform the torque into an axial thrust by means of a thrust unit. In plant areas in which explosive gases may be present, actuators must have typetested and certified explosion protection. The variety of torques and actuator speeds required in practice is met by a wide range of DREHMO actuators. DREHMO actuators can be fitted with torque and position sensor and signal processing systems to suit the various remote control requirements. The following product lines are available: > SRANGE ACTUATORS with limit and torque switches > CMATIC ACTUATORS with integral control unit > IMATIC ACTUATORS with smart integral control unit and nonintrusive setting as well as predictive maintenance features. DREHMO cmatic... with integral actuator control Cmatic actuators have an integral controlunit with builtin user interface in sturdy industrial design. The contactless torque and position measurements result from the COMBI sensor. With the LEARN function an easy setting is guaranteed. The actuators made by DREHMO contain programmable functionalities. > DREHMO 3phase AC squirrel cage motor, insulation class F, 3 thermoswitches > Combined sensor for limit and torque sensing > Controls: Switchgear: Interlocked reversing contactors Control: 24V DC, OPEN STOP CLOSE (potentialfree) Status signals: 5 changeover contacts + 4 NO contacts, > Local controls: selector switch LOCAL 0 REMOTE Control switches OPEN STOP, CLOSE, LEARN button 3 indication lights OPEN (green) FAULT (red) CLOSE (yellow) > Enclosure protection IP68 according to IEC > Ambient temperature 25 C to +70 C > Corrosion protection K3 > Handwheel for manual operation/ without switchover mechanism > Electrical connection: plug/socket connector 3

4 Overview MULTITURN ACTUATORS PARTTURN ACTUATORS THRUST ACTUATORS The design principle of multiturn actuators is to turn a multiple of 360 degrees at the output drive. They are designed to operate valves with 2 up to 1450 revolutions per stroke. Multiturn actuators are fitted mainly to gate and globe valves which transform the multiple rotation of the actuator s output drive into linear movement via a threaded stem. Multiturn actuators for openclose mostly operate shutoff valves with only a few openclose cycles per month. Flanges and output drive designs of the multiturn actuators are standardized in accordance with DIN EN ISO 5210 or DIN 3210 respectively and therefore fit on any modern valve design. Furthermore a multitude of special flange designs is available. The multiturn actuators are classified in four housing sizes according to their rated torque: 5 Nm to 60 Nm: actuator size DMC 30, Nm 250 Nm: actuator size DMC 60, 120, Nm 1000 Nm: actuator size D 250, 500, Nm 2000 Nm: actuator size D 2000 Torque values exceeding 2000 Nm are realized by additional spur or bevel gearboxes. Partturn actuators are a special type of multiturn actuator for operating butterfly, ball valves or damper, for instance, with an output drive movement of less than 360. Normally, the internal gear of the partturn actuator is designed for travel of 90 ; special ranges, such as 120 or 180 are also available. All the advantages of the planetary gear such as handwheel operation without changeover, selflocking gear, long service life, lifetime lubrication, as well as the features already described, are likewise applicable to the partturn actuators. The flange dimensions and the different output drives, such as plug bush with bore and groove, square bore and dihedron, all correspond to the usual standards, e.g. DIN EN ISO This means that direct mounting on the valve is possible. Accessories such as foot and lever with ball joints make indirect operation of butterfly valves possible depending on the structural and design conditions of the valves. Torque values exceeding 1800 Nm are realized by multiturn actuators with additional worm gears. DREHMO thrust actuators can be fitted to valves which require a linear movement. The thrust actuator transforms the torque of a DREHMO actuator into an axial thrust by means of an integrated thrust unit. The required actuating force (thrust or traction) can be adjusted continuously and reproducibly. Thrust actuators are mainly used to operate plug valves. Thrust units fitted to the flange of a multiturn actuator consist mainly of a trapezoid threaded stem, a metric screw bolt to join the valve shaft and an enclosure to protect the stem from environmental influences. The version described is used for direct mounting of the actuator to the valve. However, fork joint versions of the thrust actuators (indirect mounting) primarily operate butterfly valves for which direct mounting of a 90 part turn actuator is not possible or efficient for design reasons. Cardanic suspension of the thrust unit at the fork joint is also available. 4

5 OPERATION MODES OPENCLOSE, POSITIONING AND MODULATING DUTY Valves are driven in compliance with the required application and their design. Actuator standard EN distinguishes between three cases: > Class A: OPENCLOSE duty. The actuator is required to drive the valve through its entire travel from the fully open position to the fully closed position or vice versa. > Class B: Inching/positioning or positioning duty. The actuator is required to occasionally drive the valve to any position (fully open, intermediate and fully closed). > Class C: Modulation or modulating duty. The actuator is required to frequently drive the valve to any position between fully open and fully closed. ACTUATORS FOR OPENCLOSE DUTY AND POSITIONING DUTY (classes A and B or types of duty S2 15 min/30 min) DREHMO actuators for openclose and positioning duty are identified by type designations DMC: > DMC 30 DMC 2000 > DPMC 75 DPMC 1800 ACTUATORS FOR MODULATING DUTY (class C or types of duty S4 25 %/50 %) DREHMO actuators for modulating duty can be identified by type designations DMC: > DMC R 30 DMC R 2000 > DPMC R 75 DPMC R 1800 SWITCHING FREQUENCY AND MOTOR OPERATION MODE Modulating duty and openclose duty subject the actuator to different mechanical loads. Consequently, special actuator types are available for each operation mode. The types of duty for actuators in compliance with IEC and EN are typical distinction criteria. For modulating duty, additional indication is made of the permissible number of starts. Actuators with external positioner Actuators with integral positioner 5

6 Gear design and operating functions The DREHMO actuators basically consist of a motor, planetary gear arranged with a torquebearing displacement worm, a handwheel and an integral switching device. All parts of the planetary gear are arranged around the hollow shaft. As several teeth always mesh simultaneously with this planetary gear (unlike normal worm gears), it is possible to realize a very compact gear with a long service life. METHOD OF FUNCTIONING FOR MANUAL OPERATION Changeover from motorized to manual operation is not necessary. During manual operation via the handwheel, the forces are transmitted via the worm (9), the hollow wheel (11) and the planet wheel (4) to the driver plate (5) and then to the output drive (6). METHOD OF FUNCTIONING FOR MOTORIZED OPERATION The motor (1) drives the eccentric (3) via the spur gear (2). The planet wheel (4), which meshes into the inner gear of the hollow wheel (11), is pivoted on the eccentric (3). As the two wheels have a different number of teeth, a relative speed is generated which is transferred by driver pins (12) to the driver plate (5), which is mounted on the planet wheel (4). The driver plate (5) is interlocked with the hollow shaft (10) via serration. TORQUEDEPENDENT TRIPPING In addition to the inner gear tooth system, the hollow wheel (11) also has an outer gear tooth system which meshes with the axial displacement worm (9). The displacement worm (9) is held in its central position by pretensioned torque springs (7). If a higher torque is exerted on the actuator than the torque created by the pretensioned springs, the peripheral force on the hollow wheel (11) moves the displacement worm (9) from its central position and actuates the torque lever (8). The torque lever (8) activates the torque measurement unit (16). The related analogue torque values are used for the torque setting of the actuator and for the remote torque feedback indication. FEATURES OF THE GEAR Lifetime lubrication No mechanical switchover for handwheel operation is required No starting problems, even at low temperatures Long service life, even in modulating operation, due to low surface pressure combined with little relative movement between the meshing gears and optimum lubrication Can be mounted in any position 18 1 Enclosed Motor (TENV) Spur Gear 3 Eccentric 4 Planet Wheel 5 Driver Plate 6 Stem Nut 7 Torque Spring 8 Lever 9 Worm 10 Hollow Shaft 11 Hollow Wheel 12 Driver Pin 13 Hand Wheel 14 Local control station and LEARN button 15 Combined sensor 16 Torque Switch Unit 17 Cmatic Control Unit 18 Local indication lamps

7 Characteristic features MANUAL OPERATION As the handwheel is always in operation, manual operation is possible even if the equipment is temporarily seized e.g. if a valve is jammed in the end position. The handwheel can be operated remotely without difficulty for inaccessible actuators (see image) via corresponding linkages and bevel gears. TENV MOTORS DREHMO actuators are fitted with totally enclosed nonventilated motors (3phase asynchronous motor TENV) as standard. The motor housing is totally enclosed. This design guarantees the greatest possible protection against humidity and dust ingress and is therefore suitable for operation in extreme environmental conditions. Operating mode: Shorttime duty S2 10/15 min; in modulating operation, S4 intermittent service max. 35 % ED. Insulation class F. IEC motors and special motors Standard motors, such as singlephase or DC motors, can be supplied on request instead of TENV motors. MOTOR PROTECTION Three thermal switches connected in series are mounted in each of the motor windings individually. In case of the motor temperature exceeding 155 C the control circuit is interrupted. The contact to open the unit is integrated within the cmatic control unit. AMBIENT TEMPERATURES Basic design: 25 C to + 70 C (S2Operation) 25 C to + 60 C (S4Operation) ENCLOSURE TYPE According to IEC 70/87/CDV, EN and EN DREHMO actuators with enclosed motors are supplied as standard with enclosure type IP 68 (5 m for 24 h). PAINT COATING, CORROSION PROTECTION According to EN ISO we have rated our corrosion protection system as follow: K 3: for operation in occasionally aggressive atmospheres => C3 K 4: for operation in permanently aggressive atmospheres => C4 K 5: for operation in extremely aggressive atmospheres, such as offshore platforms or cooling towers. => C5M Other potection grades on request. ELECTRICAL CONNECTION Electrical connection is accomplished by means of a compact plug connector which connects the control and signal wires as well as the power supply (two plugs within one housing). Method of connection is screw terminals for control plug and cage clamp terminals for power supply. MECHANICAL COUPLING TYPES Multiturn actuators: Matched to the valve using coupling types and flange dimensions in accordance with DIN EN ISO 5210 or DIN Hollow shaft for ascending valve stem. Coupling types: stem nut, plug bush, bore with keyway, pawl clutch, free shaft extension. Special designs for special installation conditions are possible. Partturn actuators: Coupling types and flange dimensions in accordance with DIN EN ISO Coupling types: bore with keyway, dihedron, square bore. Thrust actuators: Coupling type in accordance with DIN 3358 COMBINED SENSOR To measure the final and intermediate position an electronic sensor is used. The two mechanical inputs for this sensor are valve position and valve torque. With this sensor and the corresponding logic board at the cmatic control unit the actuator is able to deliver potentialfree final position indication as well as an analogue 420 ma position signal proportional to valve stroke. The second sensor input is the analogue torque value. The sensor is measuring the actuator output torque required to operate the valve. Electronically the torque values can be adjusted for the switch off torque. Due to the fact that the linear movement at the worm shaft is limited at the lower values even the starting torque for the actuator can be measured and indicated. OPTIONS Conventional torque and limit switches are available. If mechanical switches are used instead of an electronic sensor a counter gear is required for the final position settings. Torque is measured by means of a mechanical torque cam operating two torque switches, one in each running direction. Limit positions and torque switch off setting values are transmitted into the logic circuit at the integral control unit. If a 420 ma position feedback is required, this is realized via a sensorpot and a mechanical adaption gear, for highest possible accurracy. Conventional torque and limit switch assembly CONFORMITY TO CE REGULATIONS DREHMO actuators comply with the EC Machinery Directive 2006/42/EC, EC Low Voltage Directive 2006/95/EC and the EMC Directive 2004/108/EC. 7

This additional equipment consists of: > reversing contactors > PLC (hardware and software units) > auxiliary voltage supplys (for heaters, contactors and signals) > external local controls > positioner The installation of these central located components for controlling and switching necessitates a high additional expenditure for: > cabinets for switch gear devices (MCC) > commissioning > project work (hardware and software) > additional buildings > documentation of the whole system The use of DREHMO cmatic actuators offers benefits for > the final customer > projecting engineers > contractors to reduce the costs of the plant in a considerable way, since all the parts required for conventional electrical controls are already integrated within the DREHMO cmatic actuators. When communication by field bus system is choosen, additional advantages result in: > accessible structure of the DCS > easy integration of additional components (actuators) > branching of bus system either integrated within actuator or at distributor cabinet > cost savings through reduced expenditure for wiring and through simplified PLC system 8

9 Features, controls and functions CHARACTERISTICS OF CMATIC The cmatic control unit is an integral part of the actuator and mounted on top of the combi sensor so that no additional housing is needed. Several advantages derive from this compact design: > Easy access to any component of the control unit > No secondary housing necessary, consequently no additional sealing The complete control unit can be hinged up (for full access) for commissioning and programming. CUSTOMER S ELECTRICAL INTERFACES: > Electrical power supply (motor) > Digital command inputs > Digital signal outputs > Auxiliary voltage output OPTIONS: > External power supply for the cmatic control unit > Analogue output for valve position > Analogue input for setpoint value of valve position > Field bus interfaces Profibus DP AUXILIARY VOLTAGE OUTPUT If there is no external power supply unit available for the command inputs, a 24 V/30 ma auxiliary voltage output is provided especially for controlling the digital input commands. CONTROLPOWER TRANSFORMER Can be used universally for various supply voltages (= motor voltage) Primary voltages: 380, 400, 415, 460, 480, 500 V, ±10 %, 50/60 Hz. Other voltages available upon request. Secondary voltage: 24 V AC (contactors) 24 V DC (control voltage). The correct primary voltage range is selected in accordance with the inscription on the control power transformer and the enclosed wiring diagram. This is preset in the factory to the supply voltage ordered. PHASE SEQUENCE CORRECTION This module ensures at a supply voltage up to 500 V that the actuator produces the correct direction of rotation for opening and closing the valve, regardless of the sequence in which the threephase network phases are applied. Whether the closing direction is to the right or left is defined by remote or local parameterization. The automatic phase sequence correction works only at 3ph AC up to 500 volt. Voltages higher than 500 volt require special diligence for correct power connection (clockwise phase sequence) according to the wiring diagram. START UP DEVICE AND LEARN FEATURES With the LEARN button at top of the local control station the settings of the final position can be simply performed without opening the actuator cover. With the local control station the actuator is moved into the required position with the OPENSTOPCLOSE control switch. After moving the actuator into the desired final position the LEARN button must be pressed together with the control switch in order to define and store the final position. Additionally the 420 ma analogue position feedback is adjusted as well. After all these values are electronically stored a loss of the setting due to power loss is not possible, respectively resetting is not neccesary. In case mechanical switches instead of combi sensors are used the setting has to be made mechanically by opening the actuator switch cover. (For more information please refer to our instruction manuals).

10 Features, controls and functions INTEGRAL LOCAL CONTROL STATION The DREHMOcmatic valve actuators are fitted as standard with a local control station with 2 toggle switches. This means that the actuator can also be controlled locally, which is a particular advantage during initial operation and in the event of failure of the primary process control engineering. The selector switch with the settings LOCAL 0 REMOTE can be locked in each setting using standard padlocks. Locking systems available upon request. Option: Remote locking of the local control station (upon request). Function: a) Selector switch in LOCAL position The actuator can be operated using the OPENSTOPCLOSED control switches on the local control station b) Selector switch in position 0 The actuator cannot be operated neither locally nor remotely c) Selector switch in REMOTE The actuator can only be operated remotely (control room). CURRENT POSITION TRANSMITTER The current position transmitter converts the movement of the output drive into an analogue signal of 4 20 ma which is proportional to the actuator travel. The supply voltage is fed within the actuator (4conductor technology) and the 2pole output signal is available for further processing in the control room. Maximum load: 300 Ohm Fitted as standard on versions MC 003, MC 005, optional on MC 004. ELECTRONIC INTERMEDIATE POSITIONS For applications that require intermediate positions in addition to the limit positions, an electronic intermediate position unit is fitted for sending status signals to the control room. Two independent intermediate positions can be preselected on the control unit via separate potentiometers. When the intermediate position set is reached, an isolated status signal is issued. The actuator motor is not switched off. Fitted as standard only in version MC 004. TIMER OPERATION The timer can be used to extend the actuating time over the entire stroke or over a userdefinable partial section up to the limit position. Selector switches can be used to configure timer operation in the opening or closing direction. A further selector switch determines whether the range for timer operation is specified using an internal setting made via potentiometers or using an optional binary input on the interface for remote commands. There are three potentiometers for parameterization of the timer operation. > Pulse time t on (0.5 s to 30 s) > Pulse time t off (0.5 s to 30 s) > Start of timer (0 % to 100 % actuator travel) Timer operation is active in the area between the limit position CLOSE (0 %) and the start of timer. Valve closing time Valve flow capacity Timer start Flow characteristic without timer Flow characteristic with timer time time Timer operation with adjustable ONOFF time Timer with positioner: When using the timer in combination with the positioner, a better performance of the whole control loop can be achieved. Hence a more sensitive and precise operation of the valve to its nominal position is practicable. SIGNAL MEMORY In case of loss of main power supply feedback signals can remain at the current status with the following options: 24 V DC external supply of control voltage or battery pack (automatic rechargeable) or tandem switches PROGRAMMING SWITCHES (DIP) To increase the adaptability of the DREHMO cmatic with regard to different applications and therefore to simplify the planning of the plant, several functions can be programmed by means of DIP switches at the control unit. The programming is done directly at the actuator, which is to change its functions of command or indication. The following functions can be set: > Travel commands holding mode or inching mode > Torque or limitrelated switchoff at the final positions OPEN and CLOSED > Torque override out of the end positions to open jammed valves (independent of the adjusted torque) > Variation of the LOCAL signal: LOCAL signal means either selector switch in position LOCAL or selector switch in position LOCAL or OFF > Running indication static or flashing > Variation of the COLLECTIVE FAULT: COLLECTIVE FAULT signal means either COLLECTIVE FAULT including TORQUE FAILURE COLLECTIVE FAULT excluding TORQUE FAILURE INTEGRAL 3POINT POSITIONER Actuators intended for modulating duty are usually operated directly by a primary process controller (e.g. pressure, temperature, flow rate) via a 4 20 ma setpoint value. The integral positioner compares the reference signal (setpoint value) with the analogue position signal generated by the actuator (actual value) and corrects the resulting difference. An adjustable potentiometer that can be used to set the sensitivity of the actuator is employed to ensure that the modulating actuator is perfectly matched to the control process over a range of 0.5 % 5 %. Should the external reference signal fail, a failsafe position that can be freely defined to match the process can be set in conjunction with programming sitches a further potentiometer. The positioner is activated by a 24 V signal on the automatic mode input. If this signal is 0 V, the actuator can be operated via digital control (24 V) using the OPEN CLOSE command inputs. Input resistance: Re = 100 Ohm; fitted as standard in version MC

14 Additional equipment SOLID STATE RELAY (ELR) Optional, solid state relays (which are free of wear) can be supplied instead of conventional, electro mechanical reversing contactors. Solid state relays are recommended for modulating actuators (high cycling rate), where conventional electro mechanical reversing contactors have a limited lifetime only. ELR type 1: Up to 500 V 3ph., 3 kw max. ELR type 2: Up to 550 V 3ph., 6 kw max. OPTION UNIT USV This option has been designed for applications in which the main power supply might be switched from the first to a second source. This requires that the actuator keeps the feedback indication for this switching period to avoid unclear or undefined information into the control system. This is realized by having an internal voltage buffer for at least 1 second. EXTERNAL VOLTAGE SUPPLY To ensure that the cmatic control unit functions correctly, and also that information contained in the actuator status signals is received, the cmatic can be externally supplied with 24 V DC + 10 %, 5 %. LOCAL LAMPS To show the status of the DREHMO at the local control station, three local lamps are fitted to the actuator housing. The following operating states can be indicated: > end position OPEN > end position CLOSED > COLLECTIVE FAULT STARTUP AND COMMISSIONING WITH LEARN FUNCTION Using the combi sensor offers a userfriendly, timesaving setting and installation after the actuator is mounted to the valve. The position setting can be easy done without opening the actuator by using the local control station combined with the LEARNbutton. 420 MA POSITION SIGNAL Available when choosing the electronic sensors for position and torque. SPECIAL MOTORS Available motors: > single phase AC motors, 230 V > DC motors from 24 V up to 220 V (only in combination with specially detached cmatic control unit) > standard threephase AC squirrel cage induction motors, several rated voltages, for short time duty S2 or S1 duty > motors with integrated brake > multiple speed motors Anyhow, the special motors require modifications of the cmatic control unit. Therefore we recommend to contact us before mapping out the plant. ELECTRONIC POSITION INDICATOR (LCDISPLAY) When choosing electronic position and torque sensors, an electronic position indicator display may be fitted instead of a mechanical dial type. Current valve position value is indicated in per cent by a numerical display. MECHANICAL DIAL POSITION INDICATOR Indication of the current valve position at the cover of the cmatic control unit is done by a mechanical dial position indicator, operated by an adjustable reduction gear (adjustable for valves from 2 to 1440 rev./stroke). Standard for version MC 003 and higher, optional to version MC002, but not available when choosing electronic position and torque sensors. MODULE POTENTIAL FREE ANALOGUE COMMANDS AND SIGNALS The voltage separation of the analogue position signal 420 ma and the analogue position command 420 ma (positioner) is done by means of a DC/DC separation amplifier for each analogue signal/ command. Either only one or all analogue signals/commands can be voltage separated. Position transducer: Maximum load = 300 Ohm Positioner: Internal resistivity R i = 100 Ohm Optional to versions MC 003 and MC 005 DETACHED CMATIC CONTROL UNIT AND DETACHED LOCAL CON TROL STATION The control unit can be mounted separately from the actuator on a wall unit. This option is recommended, respectively ingenious in case of > local control station not being accessible > ambient temperatures exceeding the rated temperature range or > mechanical stress (e.g. vibrations of pipes etc.) to the electronic reaching inadmissable values. The complete cmatic control unit is fitted to an IP67 housing with a wall unit. INTERLOCKING OF LOCAL CONTROL STATION VIA REMOTE COM MAND From the plant s control room the local control station can be interlocked or released by means of a remote command. DIAGNOSTICS CMATIC OPERATOR Allinone diagnosis, parameterising and maintenance tool for the cmatic actuators with automatical recognition of the connected hardware and easy updating of the used firmware. FIELD BUS SYSTEMS By the application of the Field Bus Interfaces the costly and costintensive parallel wiring is replaced by a serial wiring. right: Local control station with LEARNbutton, indication lamps and LC Display 14

15 The advantages being obvious by applying a field bus system, such as lower extent of installation work, a more simplified plant design, an easy opportunity for plant expansion, these all lead to the increased use of field bus systems. For different demands a number of certificated and standardized bus interface connections are available for the communication between the cmatic actuators and the higher control and master level. OPTION DATA BUS INTERFACE»PROFIBUS«DP EN The Bus interface connection for the DP Profibus is a 2wireRS485 bus interface. Its task is the conversion of the parallel commands and indicator signals of the actuators of the cmatic series to the serial bus protocol of the DP Profibus. The bus interface converts the parallel signals of the actuator to the serial protocol of the DP Profibus. Moving commands and signals of the actuator are serially transferred to the master. The data bus interface can be obtained as integrated card or as interface that may be pluggedin externally. There is also the option of implementing the acyclic services of the DPV1 profibus to enable readout of the memory for data acquisition, diagnosis information and documentation data via the fieldbus. Buszyklus mit 5 Stellantrieben 1 Standardkanal Redundanter Kanal Zyklische Prozessdatenanforderung Master Zyklische Prozessdatenrückmeldung Slave Azyklische Diagnose bzw. Parameterdatenübermittlung Controlling of the actuators by BUS system: Profibus FIELDBUS TESTMASTER The Fieldbus Testmaster is an all purpose testand diagnostics tool for commissioning of field devices. It is especially suited for commissioning of actuators equipped with Profibus DP interface. Furthermore, due to its high flexibility, communication with field devices of other manufacturers is also possible. Fieldbus Testmaster allows a cyclic communication setup with any Profibus Slave without using a GSDfile. It simply gives the opportunity to verify settings prior to warm commissioning without the use of complex and expensive PLC or SCADASystems. Thus a cost and time advantage is given. DETACHED IMATIC CONTROL UNIT/ DETACHED LOCAL CONTROL STATION If the actuator is difficult to access or in case of extreme vibration or high ambient temperatures at the place of valve installation, controls with operating elements can be mounted separately from the actuator on a wall bracket. 1 Wall bracket The actuator control is mounted on a separate wall bracket and fullfills protection class IP Detached control unit The actuator control is separated. 3 actuator housing A special housing is used to cover the sensor area. 4 Electric connection Electric connection is done by a plug/socket connector. 5 Interconnection The interconnection consists of two lines, power and data. The cable length between actuator and controls may be up to 100 m up to 100 m. 15
