design and functional principle 15 sipart ps2 manual a5e00074631-01 design and method of operation the following chapter describes the mechanical and electrical design, the instrument components and method of operation of the positioner. 2.1 overview the electropneumatic positioner forms a control system in connection with an actuator. the current position of the actuator is detected by a servo potentiometer and fed back as actual value x. the setpoint and actual value are output simultaneously on the display. the setpoint w is formed by a current fed to the positioner which at the same time serves to supply the positioner in two-wire operation. in 3 / 4-wire operation the supply comes from a 24 v voltage input. the positioner operates as a predicative five--point switch by the output variable y of which the integrated actuating valves are controlled with pulse length modulation. these actuating signals cause fluctuations in pressure in the actuator chamber(s) and thus adjustment of the actuator until the control error is zero. operation (manual) and configuration (structuring, initialization and pa- rameterization) is effected by three keys and a display with the housing cover removed. the standard controller has one digital input (di1). this can be configu- red individually and can be used for blocking the operating levels for example. with the j y -option module, the current actuator position can be output as a two wire signal j y =4to20ma. in addition the actuator can be monitored for two programmable limit values which respond on exceeding or dropping below the stroke or angle of rotation. the limit value alarms are output by the alarm option module which can monitor and report the function of the positioner and the actuator addi- tionally through a fault message output. the value of the control diffe- rence dependent on the floating time is monitored in automatic mode. the fault signal is always set when the control error cannot be leveled after a certain time because for example the valve is blocked or the mains pressure is insufficient. the three digital outputs are implemen- ted as semiconductor outputs and are error self--reporting, i.e. the out- introduction 2
design and functional principle 16 sipart ps2 manual a5e00074631-01 puts respond even when the power supply fails or the electronics are defective. the actuator can also be blocked or driven to its final positions depen- ding on the configuration for example by an external event via a digital input (di2) on the alarm module. if you require electrically independent limit value messages from the standard controller, you will have to use the sia module with the slot initiators instead of the alarm module. communication with the controller is possible via the optional hart interface. 2.2 instrument components o 90 o 33 3 14 90 33 4 2 1 15 5 6 6.1 6.2 7 8 9 10 1 1 12 13 4...20 ma 0/4...20 ma 3/4 w 2w di1 1 input: supply air 7 silencer 2 output: actuating pressure y1 8 transmission ratio selector 3 display 9 adjusting wheel slip clutch 4 output: actuating pressure y2 *) 10 terminals options modules 5 operating keys 12 dummy plug 6 restrictor 13 screw--type cable gland 6.1 restrictor y1 14 terminal plate on cover 6.2 restrictor y2 *) 15 purging air switch *) in double--acting actuators figure 2-1 view of the positioner in normal version (cover open)

design and functional principle 22 sipart ps2 manual a5e00074631-01 2.3 method of operation the electropneumatic positioner sipart ps2 forms a control circuit with the pneumatic actuator in which the actual value x is the position of the actuator bar in linear actuators or the position of the actuator shaft in rotary actuators and the command variable w is the actuating current of a controller or a manual control station of 4 to 20 ma. the stroke or rotary movement of the actuator is transferred by the appropriate mounting accessories, the feedback shaft and a play--free switchable gearwheel to a high quality conductive plastic potentiometer and to the analog input of the microcontroller. this may correct the angle error of the stroke tap, compares the potemtiometer voltage as actual value x with the setpoint w fed in at the terminals 3 and 7 and calculates the manipulated variable increments ? y. depending on the size and direction of the control error (x-w) the piezo--controlled supply air or exhaust air valve is opened. the volume of the actuator integrates the positioning increments to actuating pressure y open which moves the actuator bar or actuator shaft approximately proportionally. these positioning increments change the actuating pressure until the control error becomes zero. the pneumatic actuators are available in single and double action versions. only one pressure chamber is aerated or deaerated in the single action version. the resulting pressure operates against a spring. in the double action version, two pressure chambers are counteractive. in this case the one volume is deaerated when the other volume is aerated. see the block diagram figure 2-9, page 24. the control algorithm is an adaptive predicative five--point switch (see figure 2-8, page 23). the valves are controlled with continuous contact at large control errors (fast action zone). at medium control errors the valve is controlled by pulse length modulated pulses (slow action zone). no actuating pulses are output in the small control error zone (adaptive dead zone). the dead zone adaptation and the continuous adaptation of the minimum pulse lengths in automatic operation cause the best possible control accuracy to be achieved at the lowest switching fre- quency. the start parameters are determined during the initialization phase and stored in a non--volatile memory. these are basically the real actuating path with the mechanical limit stops, the floating times, the size of the dead zone etc. in addition the number of fault messages, changes in direction and the number of strokes are determined and stored every hour during operation. these parameters can be read out and documented by the communication programs such as pdm and ams. conclusions as to the wear on the fitting can be drawn (diagnostic function) especially by comparing the old value with the currently determined values. figure 2-9, page 24 shows the block diagrams for single-- and double-- acting actuators with the linear actuator as an example.

preparing for operation 36 sipart ps2 manual a5e00074631-01 . note the positioner will be equipped at the factory and delivered complete with the necessary options at the customer?s request. options modules may only be retrofitted by our service technicians. the positioner must be assembled ? especially in a moist environment ? in such a way as to rule out freezing of the positioner axle at low ambient temperature. the operating keys must be covered to prevent liquid getting in. ! warning in the combination of components it must be ensured that only positioners and options modules are combined which are approved for the respective area of application. this applies especially for safe operation of the positioner in areas in which the atmosphere is potentially explosive (zone 1 and 2). the instrument categories (2 and 3) of the instrument itself and those of its options must be observed. in addition, you must always make sure that no water gets into an open housing or screw--type gland. this may be the case for example when the positioner cannot be finally assembled and connected immediately. it generally applies that the positioner may only be operated with dry compressed air. therefore use the normal water traps. an additional drying unit may even be necessary in extreme cases. this is particularly important when operating the positioner at low ambient temperatures. please set the purge air switch (on the valve block above the pneumatic terminals) additionally to the ?out? position. use a sufficiently rugged console (e.g. plate thickness > 4 mm with reinforcements) for rotary actuators and the mounting kit ?linear actuator? or integrated connection for linear actuators. 3.3.1 instructions for using positioners in a wet environment this information gives you important instructions for the assembly and operation of the positioner in a wet environment (frequent, heavy rain and/or prolonged tropical condensation) in which the ip65 degree of protection is no longer sufficient and especially when there is a danger that water may freeze. to prevent water getting into the instrument in normal operation (e.g. through the exhaust air openings) or the display being poorly legible, please avoid the unfavorable installation positions illustrated in figure 3-5.
preparing for operation 37 sipart ps2 manual a5e00074631-01 figure 3-5 favorable and unfavorable installation positions if conditions oblige you to operate the positioner in a unfavorable installation position, you can take additional precautionary measures to prevent penetration by water. . note never clean the positioner with a high pressure water jet because the ip65 degree of protection is inadequate protection for this. the necessary additional measures to prevent penetration by water depend on the installation position chosen and you may additionally require: - screw--type gland with sealing ring (e.g. festo: ck ?1 / 4?pk?6) - plastic hose approx. 20 to 30 cm (e.g. festo pun-- 8x1,25 sw) - cable straps (number and length depends on local conditions) procedure - connect the pipes in such a way that rain water which runs along the pipes can drip off before it reaches the terminal strip of the positioner. - check the electrical connections for perfect firm contact. - check the seal in the housing cover for damage and contamination. clean and replace if necessary. - mount the positioner if possible so that the sinter bronze silencer faces downwards on the underside of the housing (vertical installa- tion position). if this is not possible, the silencer should be replaced by a suitable screw--type gland with a plastic hose. assembly of the screw--type gland with plastic hose - unscrew the sinter bronze silencer from the exhaust air opening on the underside of the housing. - screw the screw--type gland mentioned above into the exhaust air opening.
preparing for operation 38 sipart ps2 manual a5e00074631-01 - mount the above mentioned plastic hose on the screw--type gland and check the good fit. - fix the plastic hose with a cable strap to the fitting so that the opening faces downwards. - make sure that the hose has no kinks and the exhaust air can flow out unhindered. 3.3.2 instructions for using positioners which are exposed to great accelerations or vibrations great acceleration forces which may be far beyond the specified data occur on fittings under great mechanical stress such as breaking flaps, heavily shaking or vibrating valves as well as ?steam impacts?. this may lead to maladjustment of the slip clutch in extreme cases. please use the positioner with reinforced slip clutch for such applications. the increased torque requires a much greater force to actuate the slip clutch. applications in which the measures described above are inadequate are also conceivable. this applies for instance with continuous and heavy vibration, increased or too low ambient temperatures and in the case of nuclear radiation. the separate attachment of position displacement sensor and controller unit can help here. a universal component is available which is suitable both for linear and rotary actuators. you require the following: - the position displacement sensor unit (order no. c73451- a430-d78). this consists of a sipart-ps2- housing with integrated slip clutch, built--in potentiometer and various dummy plugs and seals. - the controller unit, any positioner version. - the emc filter plate, this is is a set together with cable clips and m-20 screw--type cable gland and has the order number c73451-a430-d23. the emc filter plate must be installed in the sipart-ps2 positioner. the installation instructions enclosed with the emc filter plate explain how to assemble the components. - a 3-wire cable for connecting the components. this retrofit kit should always be used for the controller unit when any actuator--mounted potentiometer (resistance 10 kohms) is to be used instead of the position displacement sensor unit c73451-a430-d78. external displacement measurement

preparing for operation 57 sipart ps2 manual a5e00074631-01 3.6 commissioning due to the wide range of application possibilities the positioner must be adapted (initialized) to the respective actuator individually after assem- bly. this initialization can be effected in three different ways: - automatic initialization initialization takes place automatically hereby the positioner deter- mines the direction of action, the displacement path and the angle of rotation, the adjusting times of the actuator one after the other and adapts the control parameters to the dynamic behavior of the actua- tor. - manual initialization the displacement path or angle of rotation of the actuator can be set manually, the otehr parameters are determined as in automatic initialization. this function is useful in actuators with soft limit stops. - copying initialization data (positioner exchange) in the devices with hart function the initialization data of a positio- ner can be read out and copied to another positioner. this enables a defective device to be changed without having to interrupt an ongo- ing process by initialization. only a few parameters need to be set in the positioner prior to initializa- tion. the others are defaulted so that they do not normally need to be adjusted. you will have no problems with commissioning if you observe the following points. . note you go to the previous parameter by pressing the operation mode key and the decrement key simultaneously. without initialization the positioner is in operating mode p manual operation (this may also be reached by ?prst?) -- ?noini? flashes. . note n.b.: the operating pressure should be at least one bar greater than is necessary for closing/opening the valve during initialization. n.b.: the gear transmission switch can only be set when the positioner is open. therefore check this setting before sealing the housing.
preparing for operation 58 sipart ps2 manual a5e00074631-01 3.6.1 preparations for linear actuators 1. assemble the positioner with the appropriate mounting kit (see chapter 3.3.3, page 39). . note particularly important is the position of the gear transmission switch (8, figure 2-1, page 16) in the positioner: stroke lever position of the gear transmission switch 5to20mm short 33 (i.e. down) 25 to 35 mm short 90 (i.e. up) 40 to 130 mm long 90 (i.e. up) 2. push the carrier pin (4, figure 3-6 (page 41) 2) onto the lever (6, figure 3-6, 2) to the scale position corresponding to the rated stroke or next highest position and screw the carrier pin tight with the nut (18, figure 3-6, 2). 3. connect the actuator and the positioner with the pneumatic lines and supply pneumatic power to the positioner (figure 2-3 and 2-4, page 18 ). 4. connect a suitable current or voltage source (see figure 3-12, page 49 and figure 3-13, page 50). 5. the positioner is now in the operating mode ? p-manual opera- tion ? the current potentiometer voltage (p) is displayed in percent in the top line of the display, e.g.: ? p12.3 ?, and ? noini ? flashes in the bottom line: 6. check the free running of the mechanics in the whole actuating range by moving the actuator with the keys and and driving to the respective end position. . note you can move the actuator quickly by pressing the other direction key additionally whilst keeping the direction key selected first pressed. 7. now move the actuator to the horizontal position of the lever. a value between p48.0 and p52.0 should be visible in the display. if this is not the case, adjust the slip clutch (8, figure 2-10, page 27) until ? p50.0 ? is displayed with a horizontal lever. the more accurately you hit this value, the more exactly the positioner can determine the path.

preparing for operation 72 sipart ps2 manual a5e00074631-01 3.7 copying initialization data (positioner exchange) with this function you have the possibility of starting up a positioner without running the initialization routine. this allows for example a posi- tioner to be changed on a running system in which automatic or manual initialization cannot be performed without disturbing the process. notice initialization (automatic or manual) should be performed as soon as possible afterwards because only then can the positioner be optimally adapted to the mechanical and dynamic properties of the actuator. data are transmitted from the positioner to be replaced to the replacement instrument via the hart - communication interface. the following steps must be performed to exchange a positioner: 1. read in and save instrument parameters and initialization data (determined in initialization) of the instrument to be replaced with pdm ( p rocess d evice m anager) or hart -communicator. this step is unnecessary if the instrument has been parameterized with pdm and the data have already been stored. 2. fix the actuator in its momentary position (mechanical or pneumatic). 3. read and note the current position actual value of the positioner to be changed. if the electronics are defective, determine the current position by measuring on the actuator or valve. 4. disassemble the positioner. mount the lever arm of the positioner on the replacement instrument. mount the replacement instrument on the fitting. move the gear switch to the same position as the defective instrument. copy the instrument data and initialization data from the pdm or handheld. 5. if the displayed actual value does not match the noted value of the defective positioner, set the correct value with the slip clutch. 6. the positioner is now ready to operate. the accuracy and dynamic behavior may be restricted in relation to correct initialization. the position of the hard stops and the rela- ted maintenance data may show deviations in particular. therefore initialization must be performed at the earliest opportunity.
operation 73 sipart ps2 manual a5e00074631-01 operation the following chapter describes the operation of the positioner. 4.1 display the lc display has two lines whereby the lines have different segmentation. the elements of the top line consist of 7, those of the bottom line of 14 segments. the display depends on the selected operating mode (see chapter 4.3, page 76) . note if the positioner is operated in ranges with temperatures below --10 c the liquid crystal display becomes sluggish and the display refresh rate is reduced considerably. figure 4-1 shows you the various display options. 4.2 input keys the positioner is operated by three keys (figure 4-2) the function of which depends on the selected operating mode. in the explosion proof version of the positioner the input keys are underneath a key cover which can be lifted up after loosening the cover screw. . note the input keys of the explosion proof version must be covered to prevent liquid getting in. the ip65/nema4x degree of protection is not guaranteed when the housing is open or the key cover is open. the housing cover must be removed to operate the keys in the normal and intrinsically safe versions of the positioners. 4

operation 95 sipart ps2 manual a5e00074631-01 explanations of column ?error codes?: 1 monitoring of control error in automatic operation the error between setpoint and actual value is monitored continuously. the fault message is activated with unchanged control error according to the setting of the parameters 48. tim, moni- toring time for setting the fault messages and 49 lim, response thres- hold of the fault message. as soon as the control error drops back be- low the response threshold, the fault message is reset. 2 monitoring automatic operation a fault message is generated when the instrument is not in the automa- tic mode at the appropriate parameter setting ?47. fct?. in this way the control system can be warned for example when the instrument has been switched to manual operation or configuration on site. 3 digital input di1 or di2 active a fault message is generated when the digital input is activated at the the corresponding setting of the parameter ?47. fct?, function of the fault message output and the parameter ?42.bin1?, function digital in- put 1. this may be a switch for stuffing box monitoring, a temperature switch or a limit value switch for example. digital input 2 (on the alarm module option) can be configured in the same way. 4 monitoring of number of strokes 5 monitoring of number of changes of direction the two values number of strokes and number of changes of direction are compared continuously with the limit values which are specified with the parameters ?50. strk? and ?51. dchg?. the fault message output responds when exceeded. both functions can be deactivated with the parameter setting ?off?. 6 monitoring of the bottom hard stop (valve seat) 7 monitoring of the top hard stop monitoring of the bottom hard stop is activated when the parameter ?52. zero? has a value ? off. errors of the valve seat can be detected with this function for example. exceeding of the limit value may hint at deposits or foreign bodies in the valve seat. exceeding the limit value may be caused by wear of the valve seat. mechanical maladjustment of the position feedback may also trigger this error message. monitoring takes place every time the valve is in sealing position. the current position is compared with the one determined during initializa- tion as a bottom end stop. activation of the sealing bottom function (pa- rameter ?39.ycls?) is therefore a prerequisite. example: 3% is set as a value. normally the setting 0% is adopted when sealed. if a value >3% or <--3% is determined instead, a fault is reported.
operation 96 sipart ps2 manual a5e00074631-01 the fault message remains activated until either a subsequent monitoring remains within the tolerance or a new initialization is performed. the deactivation of the monitoring (?52. zero?=off) also clears any existing fault message. this monitoring function supplies no useful results when the stops have not been determined automatically in initialization but the limits set manually (manual initialization?5.initm?). an appropriate diagnosis is made for the top hard stop. the limit value for this is set with the parameter . activation of the sealing top function (parameter ?39.ycls?) is therefore a prerequisite. 8 monitoring of the dead zone adaptation if the dead zone increases unproportionally in operation in automatic adaptation of the dead zone (parameter deba = auto) this points to an error in the system (e.g. a marked increase in stuffing box friction, play in the displacement detection, leakage). therefore a limit value can be specified for this value (?54. deba?, limit value for dead zone monitoring) which activates the fault message output when it is exceeded.
