Fitted with 3or 6 universal inputs, the KS 3002accepts signals from direct currentand voltage sources, thermocouples,and resistance thermometers.The measured data are stored in aFLASH memory, where they areavailable for display on the colourscreen. For long-term storage, the dataare written onto a CompactFlash. Bymeans of suitable software, the storeddata can also be used for subsequentevaluation and analysis on a PC.The data monitor KS 3002 is intendedfor use in industrial applications and isdesigned for panel mounting in acut-out of 138 x 138 mm. The frontpanel has protection class IP 54 andmeasures 144 x 144 mm.DESCRIPTIONMeasurement and inputsThe KS 3002 has 3 or 6 universal analoginputs for direct current and voltagesignals, thermocouples and resistancethermometers. Sensor type andmeasurement range are freelyconfigurable.Internal linearization is provided forthermocouple and resistance thermometersignals. The inputs are galvanicallyisolated by means of opto-couplers. Thesampling rate is fixed at 250 ms(regardless of the number of inputs),enabling the unit to be used as a point orline recorder.As an option, 4 digital inputs can befitted in addition to the 3 or 6 analoginputs. With the „Mathematics“ option,one analog input is required percomputation.Operation and configurationOperation and configuration of the datamonitor is menu-guided by means of 8keys in the front panel. Five of the keysare „softkeys“ whose functions arecontext-dependent. This ensuresconfident operation, because thepermitted functions are always displayedat the bottom of the screen as symbols.Unauthorized access to the configurationcan be password-protected.Configuration data can be uploaded ontoa CompactFlash from the KS 3002, ordownloaded from a CompactFlash intothe KS 3002.By means of an Engineering Tool (seeAccessories), the unit can be configuredvia a PC, with Windows 95/98 orNT/2000/XP. Subsequently, theconfiguration data can be uploaded intothe KS 3002 and changed, if necessary.The „copy“ function enables the sameparameters to be downloaded into otherunits. Furthermore, the configurationdata can be stored on a data carrier forarchiving or printing. Before the KS 3002is mounted in the panel, theconfiguration data can be loaded directlyfrom the PC via an interface cable (rAccessories).The operating language is selectableon-screen for English, German, French,Dutch, Spanish, Portuguese, Italian,Czech, Hungarian, Polish, Swedish,Danish, Russian or Finnish.The Engineering Tool provides a choiceof English, German or French.PC-based evaluation softwareThis software package (see Accessories)runs under Windows 95/98 orNT/2000/XPand is used for visualization, evaluation,administration, and archiving ofmeasurement data stored by theKS 3002.The available functions are as follows:– The data from differently-configuredmonitors is recognized and storedin a database. The entire dataadministration is executedautomatically, whereby the useronly has to enter an identifier.– The user has direct access to data thathas been specified by means of theidentifier. Furthermore, the periods tobe evaluated can be limited.– New display groups can be configuredat any time by assigning the requiredanalog and digital inputs.– An export filter enables the data to betransferred to other programs, e.g.Excel, for further calculations.

– The evaluation program supportsnetworking, i.e. several users haveindependent access to the samedata.– By means of an accessory device, thePCA communication server, the datastored in the FLASH memory of theKS 3002 can be read via the serial RS232/RS 485 interface or a modem.Readout can be triggered manually orwith a timed function.VisualizationFor visualization, the KS 3002 is fittedwith a 5-inch (126 mm) STN colourgraphics display with a resolution of320 x 240 pixels. 27 colours ensurebrilliant displays. Measured data aredisplayed vertically, as with conventionalchart recorders. By means of akey in the front panel, various displayformats are possible for the channels:numeric, scaled, bargraph, or no display. Vertical diagram with numericchannel display, no eventtracks Display width 100 mm Alarm signalling on channel 1Vertical diagram with bargraphchannel display and limitmarks, no event tracksDisplay width 100 mmSoftkeys not displayedFurthermore, it is possible to select alarge numeric display instead of thenormal (vertical) chart display. Anotherfront key enables six event tracks to beactivated for the chart display. Thisreduces the normal 100 mm displaywidth to 72 mm. If „Perforation“ hasbeen selected during parameteradjustment, the chart display showsperforations, which reduces the chartwidth to 94 mm. Vertical movement ofthe chart display depends on theselected storage cycle, and can beadjusted for mm/h, time/grid or storagecycle during parameter adjustment.Vertical diagram with channeldisplay: scaling and limitmarksSix event tracks activatedvia front keyDisplay width 72 mmSoftkeys not displayedVertical diagram withoutchannel display, withperforationDisplay width 94 mmAnother front key selects the display oranalysis of historic data. This enables allthe data stored in the ring buffer to bedisplayed with various zoom settings.The required data for zooming areselected with a cursor line.Various messages in plain text can betriggered by certain events, and arestored in the events’ list. Such eventscan be alarms, digital inputs (option) orsystem messages (e.g. mains supplyon/off). The events’ list is stored in thering buffer and on the CompactFlash.The list can also be displayed at thepush of a front key on the KS 3002.

Data processingAnalog input values are sampledcyclically at fixed intervals of 250 ms, andare stored in a buffer memory. Thestored data is checked for exceededlimits.Depending on the configuration forstorage cycle, storage mode and storagedata (min, max, mean, current ormin+max value), the measurementresults are then passed to a ring buffer(FLASH). There are three operatingmodes, each of which can be configuredfor storage cycle and storage data:• Normal mode:This is the default setting, and isused as long as there is no alarm,and timed mode has not beenselected.• Event mode:This is triggered by an externalsignal (digital input, group alarm,etc.) and remains active as long asthe trigger signal is present.• Timed mode:This mode is executed once aday during a pre-defined time.The event mode has highest priority,followed by timed mode and normalmode.The internal Flash memory is operatedas a ring buffer, and has a capacity forabout 350.000 measurement values with1MB, with 2MB it has about 850.00.When the memory is full, the oldestdata are overwritten (first in, first out).At regular intervals, the data stored in thememory is copied onto a CompactFlashin 4 kbyte blocks.The CompactFlash is a memory cardwith a capacity of 128MBytes until 2GB(industrial grade). Because every writeprocess is verified, memory faults arerecognized immediately.The unit also monitors the remainingCompactFlash capacity and generates analarm as soon as a configurable„CompactFlash change“ capacity isreached. The alarm signal can be used totrigger a relay (option). With the„CompactFlash update“ function, theCompactFlash manager copies any datafrom the Flash memory that has not yetbeen stored, before a CompactFlash isremoved.Measurement data are stored on theCompactFlash in a special encryptioncode. If the CompactFlash is removedfrom the unit, there is no immediate lossof data, because operation of the Flashmemory is not affected. Only when thememory is full, and there is noCompactFlash in the drive, data will beoverwritten.The period required until the storagecapacity of the ring buffer and theCompactFlash is exhausted, depends onthe unit’s configuration, and is variablewithin wide limits: from a few days up toseveral years.• Example:If the KS 3002 with 6 channels hasbeen adjusted to 60s in normaloperating mode, the event andtimed modes have been disabled,and only min, max, mean andcurrent values are to be stored, theresult is a recording period of about10 years for the CompactFlash 128MB, and approx. 30 days with 1MBfor the ring buffer. It is assumedthat no limit signals occur.Behaviour when separating the unit fromthe power supply– Configuration and measurement dataare maintained also after separatingthe KS 3002 from the power supply.– When the on-board lithium battery(10 years) or the buffer capacitor(typically 2 weeks) is exhausted, anydata in the Flash memory is lost, andthe internal clock stops. Because theassignment of measured values to thetime will no longer be correct, a newCompactFlash must be inserted andthe internal clock readjusted.If a limit value is exceeded, an alarm istriggered. This alarm can be routed to anoutput relay (option), or it can be used toswitch the unit to a different operatingmode (normal, event, or timed). Thedelay function enables short-term alarms(e.g. during commissioning) to beignored, so that no alarm is triggered.Furthermore, the alarm’s switchinghysteresis is adjustable.InterfaceCurrent process data as well as specialmonitor data can be output via theoptional RS 232 or RS 485 interface.Switchover between RS 232 and RS 485is done via software. With the RS 232interface, up to 15 m of cable areallowed. With RS 485, the cable can beup to 1200 m long.The interface port is a 9-pin D-typefemale connector at the rear of the unit.Transmission protocols for Modbus andJ-bus are available. The transmissionmode is RTU (Remote Terminal Unit).By means of the PCC communicationserver (see Accessories), it is possible toread the data stored in the Flash ringbuffer of the KS 3002 via the RS 232/485interface at timed intervals.The switch over between RS232 andRS485-interface is handled in theconfiguration-program.An Ethernet connection with integratedwebserver for the KS 3002 can beordered (option)TECHNICAL DATAINPUTAnalog inputsConfigurable for sensor type andmeasuring range.Galvanic isolation between inputs:up to 30 VAC or 50 VDC by means ofopto-couplers.Sampling rate250 ms for 3 or 6 inputs.Resolution: >14 bitsThermocouplesTypeMax. meas. rangeFe-CuNi „L“–200 ... + 900 CFe-CuNi „J“–210 ... +1200 CCu-CuNi „T“–270 ... + 400 CCu-CuNi „U“–200 ... + 600 CNiCr-CuNi „E“ –270 ... +1000 CNiCr-Ni „K“–270 ... +1372 CNiCrSi-NiSi „N“ –270 ... +1300 CSmallest span: 100 KMeasurement error:±0,1% referred to max. measuring range(only guaranteed above -100 °C withType J, above -150 °C with Types U andT, and above -80 °C with Types K, E, andN).3
