More see page 53.HART version: When using ‘Communication’ (an a.c. signalwhich modulates on the 4-20 mA signal), it must be ensuredthat the connected outputs, buffer amplifier and barriers arecompatible with the frequency ranges used. In addition tothe load, the AC impedance requirements must be met.Therefore, it is recommended that only the specified amplifier,barrier and configuration device be used.More see page 53.To prevent crosstalk between lines and reduce disturbances through electromagnetic influences, it is recommendedthat twisted-pair shielded lines be used, with a diameter ofAWG 22 - 14 (0,3.2,5 mm2 ) and a max. capacity of 100pF/m.The line capacities and connected devices may not exceedthe maximum values listed for a particular HART protocol.All components which are connected to the SRD in an explosion hazardous area, require an Ex-Approval. The applicable limit values must not be exceeded. These limitvalues also have to be adhered to when connectingadditional capacitances, inductances, voltage or currentsources.P C SI/A S e r ie s S y s te mw ith F B M 2 1 5 / 2 1 8w ith IF D C - S o ftw a r eC o n fig u r a tio n a n dO p e r a tin g s o ftw a r ee .g .

8SRD991MI EVE0105 E-(en)1 METHOD OF OPERATION1.1 GeneralThe positioner can be attached to both linear and rotaryactuators.Actuators with spring force are controlled by a single actingpositioner. Actuators without spring force are controlled by adouble acting positioner.The intelligent positioner SRD991 1 and the pneumatic actuator 2 form a control loop with the setpoint value w (frommaster controller or control system), the output pressure yand the position x of the actuator on valve 3 .B u swHART or FoxCom version:The positioner can be operated locally by means of localkeys, Hand Held Terminal, remotely via PC-basedconfiguration or a corresponding control system, e.g. I/ASeries System.yx!PROFIBUS-PA or FOUNDATION Fieldbus version:The positioner can be operated locally by means of localkeys, remotely via a corresponding control system, or canbe operated via PC-based configuration and operating toolse.g. PC20 / IFDC.Fig.: Fieldbus versionFor the supply air, we recommend theFOXBORO ECKARDT FRS923 filter regulator.1.2 Block diagrams2 11 72 08Input (w) eachacc. to version:4.20 mA( FSK)FSK13.36 V DC Bus input1 91 191 41 31 2) Digital operation1 6,1.

The power value ismeasured, in A/D transformer 9 converted, and directed viaswitch 10 to digital controller 11 .With PROFIBUS-PA or FOUNDATION Fieldbus, the SRDis powered by means of the bus cable. The positioner isoperated from a control system by sending a setpoint (setpoint value) to the positioner. The digital signal is directedvia the interface component 8 to the digital controller 11.By means of the voltage converter 7 the internal supply ofthe electronics is established, fed via the bus cable.With FoxCom digital operation a DC voltage is provided atinput w. On this voltage a FSK-signal is modulated. Themodulation contains information (eg setpoint value), sentdigitally to the control unit 11 across the FSK-unit 8 .The output of controller 11 drives the electro-pneumaticconverter (IP-module) 12, controlling a pre-amplifier 13, thesingle acting (or double acting) pneumatic power amplifier14. The output of the amplifier 14 is the output pressure yto the actuator.The pneumatic amplifiers are supplied with supply air s1.4 to 6 bar (20 to 90 psig).The position x of the actuator is sent to the control unit 11by the position sensor (conductive plastic potentiometer)15.Optional gauges 16 , pressure sensors 19 , 20 , inputs / outputs 21 (two binary outputs; a 4-20 mA output and alarm;control inputs for ‘Open/Close’ and ‘Hold last value’) enableadditional diagnostic indications and possible intervention.The mechanical limit switch 22 (optional) enables independent alarm signals.Adjusting, start-up of the positioner as well as the demandfor internal information can be made using the local keys 17with indication given by LCD, 18 or LEDs.
MI EVE0105 E-(en)2 OPERATING MODESOperation of the positioner is divided into individual ‘operating modes’. Operating modes may change depending on,for example, key commands or internal calculations.The different operating modes are described in abbreviatedform below.INITIALIZE:Upon power-up or Reset (pressing of the 3 keys simultaneously), several self-tests are conducted. Individual steps inthe self-test process are indicated by the LCD or greenLEDs.If no error occurs the device moves to OUT OF SERVICE,if it is still in a delivery condition; AUTOSTART has to beperformed. If AUTOSTART was done already, the devicewill go to IN OPERATION.If faults are detected, the code of the faulty self-test willremain (see page 48). If error reoccurs after reset, thedevice is probably defective and should be sent in forrepair.DEVICE FAULT:In the event that the LCD shows a message (or red LEDlights up constantly and all green LEDs are off), a devicefault is signaled. These faults are detected during cyclicalself-test.The device can no longer be operated. This could be caused by a jammed menu key, defective program memory,etc. (see chapter “Trouble-shooting”).If a device error occurs re- peatedly, the device should besent in for repair.IN OPERATION:After performing an AUTOSTART, the device moves toIN OPERATION and will always, even after restarting or resetting, move back to the safety position (de-energizedvalve position) or FAILSAFE. If setpoint values are fed viacommunication, the SRD will go to IN OPERATION.FAILSAFE:Positioner carries out actions as configured in menu “failurehandling”. Additionally, the cyclical self-diagnosis takesplace.If the instrument is IN OPERATION, but no setpoint valuesarrive via communication, the SRD will go to FAILSAFEmode, after a defined time period; either with– maintaining last value– output pressureless, or– with predetermined position.As soon as setpoint values arrive via communication again,the instrument is immediately back IN OPERATION.SRD9919OUT OF SERVICE:The SRD991 in delivered condition is configured in such away that it will remain OUT OF SERVICE after power-upuntil moving to IN OPERATION via the manually initiatedfunction AUTOSTART.In the device state OUT OF SERVICE, the menu enteringmode remains active at all times. If a device has been INOPERATION already and is removed from an actuator andmounted to another, it is recommended to take the deviceout of operation via RESET CONFIG (Menu 9.1) prior todisconnecting the device from the first actuator.This enables the next actuator to be started in the deliveredcondition (see chapter 8).CALIBRATE:During an AUTOSTART function the device is in conditionCALIBRATION. The actuator is moved up- and downwardseveral times, and the device could be busy for a fewminutes. Subsequently, the device moves to INOPERATION.MESSAGE:The SRD991 continuously supervises important devicefunctions. In the event that limit values are exceeded oroperational problems occur, messages are signaled via theLCD or the special LED blinking mode.The message with the highest priority will be indicated first.With key DOWN additional messages can be called up,with key UP the measuring values can be retrieved. It ispossible at all times to reach the menu by pressing themenu keys to possibly eliminate the problem by performingsuitable menu functions. Further references may be foundin chapter “Trouble-shooting”.SIMULATE (FOUNDATION FIELDBUS version only)During function IN OPERATION, the valve position queriedvia the communication, can be simulated with a value thathas been entered via communication into the instrumentduring position SIMULATION. Thereby the positionercontinues with normal operation and regulates to the”accurate” set value.For the SRD, this function has to be additionally released orblocked via menu 10.LCD description, definition of the LEDs and possible operator interventions are described in chapter: START-UP.
