Power-on sequenceThe CXA2050S does not have an internal power-on sequence. Therefore, power-on sequence is all controlled by the set microcomputer (I2C bus controller).1) Power-onThe IC is reset and the RGB outputs are all blanked. Hdrive starts to oscillate, but oscillation is at the maximum frequency (16kHz or more) and is not synchronized to the input signal. Output of vertical signal VTIM starts, but Vdrive is DC output. Bus registers which are set by power-on reset are as follows.AGING= 0: All white output aging mode OFFRON= 0: Rch video blanking ONGON= 0: Gch video blanking ONBON= 0: Bch video blanking ONPICON= 0: RGB all blanking ONVOFF= 1: VDRIVE output stopped modeVFREQ= 0: Automatic identification mode (identification starts at 50Hz)FHHI= 1: H oscillator maximum frequency modeHSIZESW= 0: NormalCD-MODE= 0: Automatic selector mode of the countdown modeAKBOFF= 0: AKB mode2) Bus register data transferThe register setting sequence differs according to the set sequence.

To replace the lamp, check the model number of the replacement lamp (sold separately) and Replacement lamp model number: DT00531If the projector is mounted on the ceiling, or if the lamp has broken, ask your dealer to replace the lamp. Lamp replacement is hazardous and should not be attempted by the user.Before replacing the lamp, make sure the power switch is off and the power cable is not plugged in, then wait at least 45 minutes for the lamp to cool sufficiently. Handling the lamp while hot can cause burns, as well as damaging the lamp.The LCD projector uses a glass lamp bulb. It is a mercury lamp with highinternal pressure. High-pressure mercury lamps can break with a loud bang, or burn out, if jolted or scratched, or through wear over time. Each lamp has a different lifetime, and some may burst or burn out soon after you start using them. In addition, when the bulb bursts, it is possible for shards of glass to fly into the lamp housing, and for gas containing mercury to escape from the projectorDo not open the lamp cover while the projector is suspended from above. This iss bulb has broken, the shards will fall out when the cover is opened. In addition, working in high places is dangerous, so ask your local dealer to have the lamp replaced even if the bulb is not broken.Handle with care: jolting or scratching could cause the lamp bulb to burst during use.If the replace lamp indicator (see "Related Messages" (Vol.2 ) and "Regarding the indicator Lamps" (Vol.2 )) comes on, replace the lamp as soon as possible. Using the lamp for long periods of time, or past the replacement date, could cause it to burst. Do not use old (used) lamps; this is a cause of breakage.If the lamp breaks soon after the first time it is used, it is possible that there are electrical problems elsewhere besides the lamp. If this happens, contact your local dealer or a service representative.MENU button.Use the lever switchor ENTER button.Use the lever switchENTER button.Return menu to last previous screen:Press thePerform the operation using the lever switch(For further details, read the explanation for each separate menu.)During operation, press the RESET button.(Functions that are executed at the same timeas a selection, including H PHASE, LANGUAGEselection, and ADJUST, will not be reset.)B Input or Hi-Vision 1125i(1035i/1080i)/750p of COMPONENT VIDEOInput:At VIDEO Input, S-VIDEO Input or 525i/525p/625i of COMPONENT VIDEO Input:• The SMALL picture may not be displayed correctly with certain input signals.Select Picture Position (for 16:9/SMALL Picture):CENTERSelect Gamma Mode:NORMAL CINEMASelect Mirror Status:NORMAL H:INVERTSelect Menu Language:FRANÇAIS DEUTSCH ESPAÑOLNEDERLANDSPOTUGUÊSAdjust Sharpness (for VIDEO/S-VIDEO):Adjust COLOR (for VIDEO/S-VIDEO/COMPONENT VIDEO):Adjust Tint (for VIDEO/S-VIDEO):RedLeftAdjust Horizontal Phase (for RGB/COMPONENT VIDEO):• Adjust to eliminate flicker.Adjust Horizontal Size (for RGB):• If the horizontal size adjustment is excessive, the image may not be displayed correctly.

It is designed for home/project/professional studio applications and live performance.The microphone requires 11V to 52V phantom power for operation.The omnidirectional polar pattern is sensitive to sound coming fromall directions. Select the omni pattern to pick up several voices orinstruments on the same microphone, to diminish proximity effect, andto preserve the location’s ambient sound.The cardioid polar pattern is more sensitive to sound originating directlyin front of the element, making it useful in controlling feedback, reducingpickup of unwanted sounds and providing isolation between performers.The figure-of-eight polar pattern is more sensitive to sound originating inthe front and back of the microphone, rejecting sounds from the sides.It is often used in conjunction with advanced stereo miking techniques.The output of the microphone is a 3-pin XLRM-type connector.The microphone is equipped with a switchable 10 dB pad and a switchthat permits choice of flat response or low-frequency roll-off (via integral80 Hz high-pass filter).The microphone is enclosed in a rugged housing. The included AT8458shock mount provides superior isolation and permits mounting on anymicrophone stand with 5/8"-27 threads. A soft protective pouch is alsoincluded.Operation and MaintenanceThe AT2050 requires 11V to 52V phantom power for operation.Output is low impedance (Lo-Z) balanced. The signal appears across Pins2 and 3; Pin 1 is ground (shield). Output phase is “Pin 2 hot”—positiveacoustic pressure produces positive voltage at Pin 2.To avoid phase cancellation and poor sound, all mic cables must be wiredconsistently: Pin 1-to-Pin 1, etc.An Audio-Technica emblem and the pattern-selection switch are on thefront of the microphone. Position this side of the microphone toward thesound source.The pattern-selection switch provides user-selection of omnidirectional,cardioid, and figure-of-eight polar patterns. To select the omnidirectionalpolar pattern, slide the switch to the circular polar pattern image. Toselect the cardioid polar pattern, slide the switch to the heart-shapedpolar pattern image. To select the figure-of-eight pattern, slide the switchto the figure-eight shaped polar pattern image.An integral 80 Hz high-pass filter provides easy switching from a flatfrequency response to a low-end roll-off. The roll-off position reduces themicrophone’s sensitivity to popping in close vocal use. It also reducesthe pickup of low-frequency ambient noise (such as traffic, air-handlingsystems, etc.), room reverberation and mechanically coupled vibrations.To engage the high-pass filter, slide the switch toward the “bent” line.The microphone is also equipped with a switchable 10 dB pad that lowersthe microphone's sensitivity, thus providing higher SPL capability forflexible use with a wide range of users and system configurations. Toengage the 10 dB pad, slide the switch toward the -10 position.In use, secure the cable to the mic stand or boom, leaving a slack loop atthe mic. This will ensure the most effective shock isolation and reducethe possibility of accidentally pulling the microphone out of its mount.Avoid leaving the microphone in the open sun or in areas wheretemperatures exceed 110° F (43° C) for extended periods. Extremely highhumidity should also be avoided.Architect’s and Engineer’s SpecificationsThe microphone shall be a large-diaphragm side-address externallypolarized (DC bias) condenser with user-switchable omnidirectional,cardioid, and figure-of-eight polar patterns and a frequency response of20 Hz to 20,000 Hz.

LEDs➤Measurements compensated for current and temperature ➤Self-discharge compensation us-ing internal temperature sensor ➤16-pin narrow SOICGeneral DescriptionThe bq2050Lithium Ion Power Gauge™IC is intended for battery-pack or in-system installation to maintain an accurate record of available battery capacity.The IC monitors a voltage drop across a sense resistor connected in series between the negative battery termi-nal and ground to d e t e r m i n e charge and discharge activity of the battery .Compensations for bat-tery temperature and rate of charge or discharge are applied to the charge,discharge,and self-discharge calculations to provide available ca-pacity information across a wide range of operating conditions.Bat-tery capacity is automatically recali-brated,or “learned,”in the course of a discharge cycle from full to empty .Nominal available capacity may be directly indicated using a five-segment LED display.These seg-ments are used to graphically indi-cate available capacity .The bq2050supports a simple single-line bidi-rectional serial link to an external processor (common ground).The bq2050outputs battery information in response to external commands over the serial link.The bq2050may operate directly from one cell (V BAT >3V).With the REF output and an external transis-tor,a simple,inexpensive regulator can be built for systems with more than one series cell.Internal registers include available capacity ,temperature,scaled avail-able energy,battery ID,battery status,and programming pin set-tings.To support subassembly test-ing,the outputs may also be con-trolled.The external processor may also overwrite some of the bq2050power gauge data registers.LCOMLED common output SEG 1/PROG 1LED segment 1/program 1 input SEG 2/PROG 2LED segment 2/program 2

capacity by monitor-ing the amount of current input to or removed from a rechargeable battery.The bq2050measures dis-charge and charge currents,measures battery volt-age,estimates self-discharge,monitors the battery for low battery voltage thresholds,and compensates for temperature and charge/discharge rates.The cur-rent measurement is made by monitoring the voltage across a small-value series sense resistor between the negative battery terminal and ground.The estimate of scaled available energy is made using the remaining average battery voltage during the discharge cycle and the remaining nominal available charge.Thescaled available energy measurement is corrected for the environmental and operating conditions.Figure1shows a typical battery pack application of the bq2050using the LED display capability as a charge-state indicator.The bq2050is configured to display ca-pacity in relative display mode.The relative display mode uses the last measured discharge capacity of the battery as the battery“full”reference.A push-button display feature is available for momentarily enabling the LED display.The bq2050monitors the charge and discharge currents as a voltage across a sense resistor(see R S in Figure1).A filter between the negative battery terminal and theSR pin may be required if the rate of change of the bat-tery current is too great.3bq2050Figure 1. Battery Pack Application Diagram—LED DisplayVoltage ThresholdsIn conjunction with monitoring V SR for charge/discharge currents,the bq2050monitors the battery potential through the SB pin.The voltage is determined through a resistor-divider network per the following equation:RB1 RB22N=−1where N is the number of cells,RB1is connected to the positive battery terminal,and RB2is connected to the negative battery terminal.The single-cell battery volt-age is monitored for the end-of-discharge voltage(EDV). EDV threshold levels are used to determine when the battery has reached an“empty”state.Two EDV thresholds for the bq2050are programmable with the default values fixed at:EDV1(early warning)=1.52VEDVF(empty)=1.47VIf V SB is below either of the two EDV thresholds,the as-sociated flag is latched and remains latched,independ-ent of V SB,until the next valid charge.The V SB value is also available over the serial port.During discharge and charge,the bq2050monitors V SR for various thresholds used to compensate the charge and discharge rates.Refer to the count compensation section for details.EDV monitoring is disabled if thedischarge rate is greater than2C(typical)andresumesafter the rate falls below2C.RBI InputThe RBI input pin is intended to be used with a storage ca-pacitor or external supply to provide backup potential to the internal bq2050registers when V CC drops below3.0V.V CC is output on RBI when V CC is above3.0V.A diode is re-quired to isolate the external supply.ResetThe bq2050can be reset either by removing V CC and grounding the RBI pin for15seconds or by writing0x80 to register0x39.TemperatureThe bq2050internally determines the temperature in 10°C steps centered from approximately-35°C to+85°C. The temperature steps are used to adapt charge and dis-charge rate compensations,self-discharge counting,and available charge display translation.The temperature range is available over the serial port in10°C incre-ments as shown in the following table:Layout ConsiderationsThe bq2050measures the voltage differential between the SR and V SS pins.V OS(the offset voltage at the SR pin)is greatly affected by PC board layout.For optimal results,the PC board layout should follow the strict rule of a single-point ground return.Sharing high-current ground with small signal ground causes undesirable noise on the small signal nodes.Additionally:n The capacitors(C1and C2)should be placed as close as possible to the V CC and SB pins,respectively,and their paths to V SS should be asshort as possible.A high-quality ceramic capacitor of0.1µf is recommended for V CC.n The sense resistor capacitor should be placed as close as possible to the SR pin.n The sense resistor(R S)should be as close as possible to the bq2050.4bq2050TMP (hex)Temperature Range0x< -30°C1x-30°C to -20°C2x-20°C to -10°C3x-10°C to 0°C4x0°C to 10°C5x10°C to 20°C6x20°C to 30°C7x30°C to 40°C8x40°C to 50°C9x50°C to 60°CAx60°C to 70°CBx70°C to 80°CCx> 80°CGas Gauge OperationThe operational overview diagram in Figure2illustrates the operation of the bq2050.The bq2050accumulates a measure of charge and discharge currents,as well as an estimation of self-discharge.Charge and discharge cur-rents are temperature and rate compensated,whereas self-discharge is only temperature compensated.The main counter,Nominal Available Capacity(NAC), represents the available battery capacity at any given time.Battery charging increments the NAC register, while battery discharging and self-discharge decrement the NAC register and increment the DCR(Discharge Count Register).The Discharge Count Register(DCR)is used to update the Last Measured Discharge(LMD)register only if a complete battery discharge from full to empty occurs without any partial battery charges.Therefore,the bq2050adapts its capacity determination based on the actual conditions of discharge.The battery's initial capacity is equal to the Pro-grammed Full Count(PFC)shown in Table2.Until LMD is updated,NAC counts up to but not beyond this threshold during subsequent charges.This approach al-lows the gas gauge to be charger-independent and com-patible with any type of charge regime.st Measured Discharge(LMD)or learnedbattery capacity:LMD is the last measured discharge capacity of thebattery.On initialization(application of V CC or bat-tery replacement),LMD=PFC.During subsequentdischarges,the LMD is updated with the latestmeasured capacity in the Discharge Count Register(DCR)representing a discharge from full to belowEDV1.A qualified discharge is necessary for a capac-ity transfer from the DCR to the LMD register.TheLMD also serves as the100%reference thresholdused by the relative display mode.5bq2050Figure 2. Operational Overview2.Programmed Full Count (PFC)or initial bat-tery capacity:The initial LMD and gas gauge rate values are pro-grammed by using PROG 1–PROG 4.The bq2050is configured for a given application by selecting a PFC value from Table 2.The correct PFC may be determined by multiplying the rated battery capac-ity in mAh by the sense resistor value:Battery capacity (mAh)*sense resistor (Ω) =PFC (mVh)Selecting a PFC slightly less than the rated capac-ity provides a conservative capacity reference until the bq2050“learns”a new capacity reference.Example:Selecting a PFC Value

bq2050“learns”a new capacity with a qualified discharge from full to EDV1.3.Nominal Available Capacity(NAC):NAC counts up during charge to a maximum value of LMD and down during discharge and self-dis-charge to0.NAC is reset to0on initialization and on the first valid charge following discharge to EDV1.To prevent overstatement of charge during periods of overcharge,NAC stops incrementing when NAC= LMD.4.Discharge Count Register(DCR):The DCR counts up during discharge independent of NAC and could continue increasing after NAC has decremented to0.Prior to NAC=0(empty battery), both discharge and self-discharge increment the DCR.After NAC=0,only discharge increments the DCR.The DCR resets to0when NAC=LMD.The DCR does not roll over but stops counting when it reaches FFFFh.The DCR value becomes the new LMD value on the first charge after a valid discharge to V EDV1if:No valid charge initiations(charges greater than 256NAC counts,where V SRO>V SRQ)occurred dur-ing the period between NAC=LMD and EDV1de-tected.The self-discharge count is not more than4096 counts(8%to18%of PFC,specific percentage threshold determined by PFC).The temperature is≥0°C when the EDV1level is reached during discharge.The valid discharge flag(VDQ)indicates whether the present discharge is valid for LMD update.5.Scaled Available Energy(SAE):SAE is useful in determining the available energy within the battery,and may provide a more useful capacity reference in battery chemistries with sloped voltage profiles during discharge.SAE may be converted to a mWh value using the following formula:E(mWh) =(**SAEH SAEL)256+24.)∗∗+∗SCALE(R RR RB1B2S B2where R B1,R B2and R S are resistor values in ohms.SCALE is the selected scale from Table2.SAEHand SAEL are digital values read via DQ.pensated Available Capacity(CAC)CAC counts similar to NAC,but contains the avail-able capacity compensated for discharge rate andtemperature.Charge CountingCharge activity is detected based on a positive voltage on the V SR input.If charge activity is detected,the bq2050increments NAC at a rate proportional to V SR and, if enabled,activates an LED display.Charge actions in-crement the NAC after compensation for temperature.The bq2050determines charge activity sustained at a continuous rate equivalent to V SRO>V SRQ.A valid charge equates to sustained charge activity greater than256NAC counts.Once a valid charge is detected, charge counting continues until V SRO(V SR+V OS)falls below V SRQ.V SRQ is210µV,and is described in the Digital Magnitude Filter section.Discharge CountingDischarge activity is detected based on a negative voltage on the V SR input.All discharge counts where V SRO<V SRD cause the NAC register to decrement and the DCR to increment.V SRD is-200µV,and is described in the Digital Magnitude Filter section.Self-Discharge EstimationThe bq2050continuously decrements NAC and increments DCR for self-discharge based on time and temperature.Thecount rate is programmed to be a nominal *NAC per day or disabled.This is the rate for a bat-whose temperature is between20°–30°C.The NAC register cannot be decremented below0.Count CompensationsDischarge CompensationCorrections for the rate of discharge,temperature,and anode type are made by adjusting an internal compensation factor.This factor is based on the measured rate of discharge of the battery.Tables3A and3B outline the correction factor typi-cally used for graphite anode Li-Ion batteries,and Tables4A and4B outline the factors typically used for coke anode Li-Ion batteries.The compensation factor is applied to CAC and is based on discharge rate and temperature.7bq2050Charge CompensationThe bq2050applies the following temperature compen-sation to NAC during charge:This compensation applies to both types of Li-Ion cells.Self-Discharge CompensationThe self-discharge compensation is programmed for a nominal rate of *NAC per day .This is the rate for a battery within 20°C–30°C temperature range.This rate varies across 8ranges from <10°C to >70°C,chang-ing with each higher temperature (approximately 10°C).See Table 5below:Self-discharge may be disabled by connecting PROG 5=H.Digital Magnitude FilterThe bq2050has a digital filter to eliminate charge and dis-charge counting below a set threshold.The bq2050setting is 200µV for V SRD and 210µV for V SRQ .8bq2050Table 5.

Coke AnodeTemperature Temperature CompensationFactorEfficiency <10°C 0.9595%≥10°C1.00100%Error SummaryCapacity InaccurateThe LMD is susceptible to error on initialization or if no updates occur.On initialization,the LMD value in-cludes the error between the programmed full capacity and the actual capacity.This error is present until a valid discharge occurs and LMD is updated(see the DCR description on page7).The other cause of LMD er-ror is battery wear-out.As the battery ages,the meas-ured capacity must be adjusted to account for changes in actual battery capacity.A Capacity Inaccurate counter(CPI)is maintained and incremented each time a valid charge occurs(qualified by NAC;see the CPI register description)and is reset whenever LMD is updated from the DCR.The counter does not wrap around but stops counting at255.The ca-pacity inaccurate flag(CI)is set if LMD has not been up-dated following64valid charges.Current-Sensing ErrorTable5illustrates the current-sensing error as a func-tion of V SRO.A digital filter eliminates charge and dis-charge counts to the NAC register when V SRO is between V SRQ and V SRD.Communicating With the bq2050The bq2050includes a simple single-pin(DQ plus re-turn)serial data interface.A host processor uses the in-terface to access various bq2050registers.Battery char-acteristics may be easily monitored by adding a single contact to the battery pack.The open-drain DQ pin on the bq2050should be pulled up by the host system,or may be left floating if the serial interface is not used.The interface uses a command-based protocol,where the host processor sends a command byte to the bq2050. The command directs the bq2050to either store the next eight bits of data received to a register specified by the command byte or output the eight bits of data specified by the command byte.The communication protocol is asynchronous mand and data bytes consist of a stream ofeight bits that have a maximum transmission rate of 333bits/sec.The least-significant bit of a command or data byte is transmitted first.The protocol is simple enough that it can be implemented by most host proces-sors using either polled or interrupt processing.Data input from the bq2050may be sampled using the pulse-width capture timers available on some microcontrol-lers.If a communication error occurs,e.g.t CYCB>6ms,the bq2050should be sent a BREAK to reinitiate the serial interface.A BREAK is detected when the DQ pin is driven to a logic-low state for a time,t B or greater.The DQ pin should then be returned to its normal ready-high logic state for a time,t BR.The bq2050is now ready to receive a command from the host processor.The return-to-one data bit frame consists of three dis-tinct sections.The first section is used to start the transmission by either the host or the bq2050taking the DQ pin to a logic-low state for a period,t STRH,B.The next section is the actual data transmission,where the data should be valid by a period,t DSU,after the negative edge used to start communication.The data should be held for a period,t DV,to allow the host or bq2050to sample the data bit.The final section is used to stop the transmission by re-turning the DQ pin to a logic-high state by at least a pe-riod,t SSU,after the negative edge used to start commu-nication.The final logic-high state should be held untila period,t SV,to allow time to ensure that the bit trans-mission was stopped properly.The timings for data and break communication are given in the serial communi-cation timing specification and illustration sections.Communication with the bq2050is always performed with the least-significant bit being transmitted first.Figure3 shows an example of a communication sequence to read the bq2050NAC register.9bq2050Symbol Parameter Typical Maximum Units NotesINL Integrated non-linearityerror±2±4%Add 0.1% per °C above or below 25°Cand 1% per volt above or below 4.25V.INR Integrated non-repeatability error±1±2%Measurement repeatability givensimilar operating conditions.Table 6. bq2050 Current-Sensing Errorsbq2050 RegistersThe bq2050command and status registers are listed in Table7and described below.Command Register(CMDR)The write-only CMDR register is accessed when eight valid command bits have been received by the bq2050.

All the safety instructions and advice notes are to be observed.Neither SCHAFFNER Elektronik AG, Luterbach, Switzerland nor any of the subsidiary sales organisations can accept any responsibility for personal, material or consequential injury, loss or damage that results from improper use of the equipment and accessories.1.1 GeneralUse of the generator is restricted to authorised and trained specialists.The generator is to be used only for the purposes set down by the manufacturer.The construction of the unit renders it unsuitable for use in an explosive atmosphere.Persons fitted with a heart pacemaker must not operate the instrument nor approach the test rig while it is in operation.Only approved accessory items, connectors, adapters, etc. are to be used to ensure safe operation.Safety measures are described in these instructions as follows:WARNING:For potential dangers that could result in seriousinjury or death.CAUTION:For potential dangers or where careless handlingcould cause light injuries or material damage.1-4PNW 2051 SCHAFFNER TEST EQUIPMENT 1.2 InstallationThe instrument conforms to protection class 1, but with an increased leakage current.Local installation regulations must be respected to ensure the safe flow of leakage currents.Operation without a protective earth connection is forbidden!Two independent protective earth connections are necessary (instrument and EUT supply) connected back to the local permanent installation or to a fixed, permanent protective earth conductor.Operate the equipment only in dry surroundings. Any condensation that occurs must be allowed to evaporate before putting the equipment into operation. Do not exceed the permissible ambient temperature, humidity or altitude.Use only nationally approved connectors and accessory items.Ensure that a reliable return path for the interference current is provided between the EUT and the generator. The reference ground plane and the earth connections to the instruments as described in the relevant test standard serve this purpose well.The instruments must generally not be opened. This may only be undertaken by a qualified specialist if specifically instructed to do so in the operating manual. Depending on the Pulse Network (PNW) utilised, the equipment can work with two independent power supplies, one for the generator and one for the EUT. Besides the mains supply itself, certain instruments or parts thereof, also operate at high voltages which are not provided with any internal form of extra protection against being touched.1-5SCHAFFNER TEST EQUIPMENT PNW 2051 1.3 Test executionThe test area must be so organised that no unauthorised persons have access during execution of a test. If a safety contact (interlock) is used as a means of access control to the test zone (e.g. Faraday cage), then an additional contact in series is necessary to provide protection for parts of the EUT that are in danger of being touched.EUTs, together with their accessories and cables, are to be considered as being live during a test. The test generator must be stopped and the EUT supply interrupted before any work is carried out on the EUT. This can be implemented by opening the interlock circuit, but depends on the type of generator in use.The EUT is to be tested only in a protective cage or under a hood which provides protection against electric shock and all manner of other dangers pertaining to the particular EUT (see “Dangers concerning the EUT”).The safety instructions concerning all the instruments and associated equipment involved in the test rig are to be observed.The configuration of the test rig is strictly to be in compliance with the methods described in the relevant standard to ensure that the test is executed in a standard-conform manner.1.4 Dangers concerning the generator• Local burning, arcing, ignition of explosive gases.• Danger from the resultant EUT supply current caused by a flash-over or breakdown resulting from the superimposed high voltageeffects.• Dangers from a disrupted EUT.• Disturbance of unrelated electronics, telecommunications, navigational systems and heart pacemakers through unnoticedradiation of high frequency energy.1-6PNW 2051 SCHAFFNER TEST EQUIPMENT 1.5 Dangers concerning the EUTEUTs are often simply functional samples that have not previously been subjected to any safety tests. It can therefore happen in some cases that the EUT is quickly damaged by internal overloads caused by the control electronics being disrupted or it may even start to burn.• As soon as the EUT shows signs of being disrupted the test should be stopped and the power to the EUT switched off.• Internal disruption of the electronics can result in the interference voltage or the EUT supply voltage being present on the EUT’shousing.• Electrical breakdown or arcing in plugged connections that are over-stressed voltage-wise during the test.• Explosion of electronic components with fire or fragmentation as a result of the energy dissipated, e.g. from the resultant supply currentor ignition of vaporised plastics materials.• Faulty behaviour by the EUT, e.g. robot device strikes out, temperature controller fails, etc.1-7SCHAFFNER TEST EQUIPMENT PNW 2051 1.6 Applicable safety standardsDevelopment and manufacture is in compliance with ISO 9001.The equipment conforms to the safety requirements of IEC 1010-1 / EN 61010-1 (Safety requirements for electrical equipment for measurement, control and laboratory use).All mains driven types of generators are equipped for high voltage working safety in accordance with VDE 0104.The interference immunity has been tested in conformity with EN 50082-1.It is the user's responsibility to ensure that the test set-up does not emit excessive radiation that may affect other equipment. The generator itself does not produce any illegal radiation, however the EUT and/or the associated cables may start radiating EMI.Since the purpose of this instrument is to produce interference signals for interference immunity tests, the requirements of EN 50081-1 to limit the radiated EMI can only be complied with by operating the system inside a Faraday cage.1-8PNW 2051 SCHAFFNER TEST EQUIPMENT 2 PNW 2051The pulse network module type PNW 2051, in conjunction with the NSG 2050, produces the following pulses to satisfy the requirements of the standards:IEC 1000-4-5 (IEC801-5) / CCITT / NF C98-010 / etc.Telecom pulse 0.5/700µs10/700µs2.1 Operating modesCAUTION:Switch the mains switch on the rear panel off, before you slide the module into the main housing.• Set the instrument to “STAND-BY” with the mains switch on the rear panel. “POWER” button and the INTELOCK RESET button light up.Wait 10 sec. for processor self-test.• Switch from “STAND-BY” to ON with the “Power” button on the front panel. Display is activated and shows default settings.• Check the interlock circuit (INTL)Circuit open:Display showsInstrument cannot be switched to RUN mode norcan the EUT power be switched on.Circuit closed:Display showsInstrument is ready to RUN.Push the INTERLOCK button to reset the Interlock.

It is possible to change parameters and savethese under the chosen USER level.When USER is selected and confirmed with the ENTER key,the VOLTAGE (F3) will be displayed.NOTE:It is only in USER mode and by using the option key that the number, phase, repetition time and polarity isshown and can be changed.COUPLINGThe coupling facility is not used for this plug-in: The coupling is always via the HIGH/LOW output from the main frame.EUT-PEUT-P is not applicable to this plug-in because the pulse is always produced at the HIGH/LOW output on the NSG 2050 main frame.OPTIONSThe previous menu will re-appear when the OPTIONS key (F5) is pressed. 2.3 The USER menuLEVELThe same standard level is shown on the display with the same functions as described in the previous menu descriptions.COUPLINGThe coupling facility is not used for this plug-in. The coupling is always via the HIGH/LOW output from the main frame.VOLTAGEThe voltage level is shown on the display in inverse video when the function key F3 is pressed and the USER level is set from 1 up to 8. The required value is chosen with the rotary knob and confirmed by pressing ENTER.Selection 200 ... 6,600V in 10 volt stepsFunction Sets the output voltage levelENTER /EUT-PThe EUT power function is not used for this plug-in.OPTIONA switch to the OPTION sub-menu is made when the function key F5 is pressed. Options are only available in a USER level with following menu:PULSEThe various rise times and impedances are shown on the display in inverse video when the function key F1, PULSE, is pressed. The required value ischosen with the rotary knob and confirmed by pressing ENTER.Selection 0.5/700µs 15 Ohm0.5/700µs 40 Ohm 10/700µs 15 Ohm 10/700µs 40 OhmFunction The generator setting will specify the pulse rise time and theinternal impedance of 15Ω or 40Ω depending on the testset-up required in the standard.ENTER /NUMBERThe NUMBER of pulses is shown on the display in inverse video when the function key F2 is pressed. The required value is chosen with the rotary knob and confirmed by pressing ENTER.Selection 1 ... 9,999Function Sets the number of pulsesPHASEThe PHASE appears on the display in inverse video when function key F3 is pressed. The selection is made with the rotary knob and confirmed with ENTER.Selection ASYN; 0° ... 359° in 1° stepsFunction Angle refers to the phase angle of the EUT supply. Pulses will be sent regardless of phase angle in the asynchronousmode. Pulses may be sent at a specific phase angle whenoperating in the synchronous mode.REPetitionThe REPetition appears on the display in inverse video when function key F4 is pressed. The selection is made with the rotary knob and confirmed with ENTER.Selection 15 ... 10,000s in 1s stepsFunction The repetition time defines the period, in seconds, between the pulses.POLarityThe POLarity appears on the display in inverse video when function key F5 is pressed. The selection is made with the rotary knob and confirmed with ENTER.Selection POSitve; NEGative; ALTernateFunction Polarity controls whether the pulse is to be injected in a positive or negative sense. If Alternate is selected then thetest will be performed using both polarities alternately,executing positive polarity first. If the number of pulses isodd then the positive polarity pulses will number one less. 2.4 Save settingsAll the parameters will be automatically saved as soon as the ENTER button is pressed while in the selected USER mode.3 Test set-upTelecom pulses, as described in the standards K17 and K20 from the CCITT have been accepted by many national standards committees as being the fundamental test pulses for the telecommunications industry. The definition of the telecom pulses incorporates special characteristics. The pulse network has been precisely specified and the pulse shape is only defined under open-circuit conditions, except the 10/700µs at 40Ω condition. By using standard-conform test rigs it is possible to achieve a very high degree of reproducibility of the test results that give the user considerable assurance and confidence in the test procedures.3.1 Using the coupling network CDN 118The coupling network type CDN 118 is suitable for surge voltage tests on telecom lines. This complies with the requirements of IEC 1000-4-5 and CCITT.The requisite test parameters can be found in the standards and test specifications.Ensure that all cable connections are properly made before powering up the test rig. Suitable connecting cables are available for all CDNs and the NSG 2050.4 Technical dataPulse form: 0.5/700µs (open-circuit)10/700µs (open-circuit)Voltage: 200V ... 6,600V ± 10% adjustable in 10V steps Short-circuitcurrent: 13.3A ... 440A ± 10% into 15Ω impedance5A ... 165A ± 10% into 40Ω impedance Impedance: 15Ω, 40ΩPolarity: P (positive), N (negative), A (alternating) Pulse outputs: Earth-free (floating)Repetition: 15s ... 10,000sNumber of pulses: 1 ... 9,999Dimensions: 410 x 212 x 262mm (D x W x H)Weight: 11kg approx.Optional accessories: CDN 118。
