FMA-900 SERIESAir Velocity TransducersStandardRemote Probee-mail:**************For latest product manuals:User’sGuideShop online atIt is the policy of OMEGA Engineering, Inc. to comply with all worldwide safety and EMC/EMI regulations that apply. OMEGA is constantly pursuing certification of its products to the European New Approach Directives. OMEGA will add the CE mark to every appropriate device upon certification.The information contained in this document is believed to be correct, but OMEGA accepts no liability for any errors it contains, and reserves the right to alter specifications without notice.WARNING: These products are not designed for use in, and should not be used for, human applications.General DescriptionThe OMEGA ®FMA-900 air velocity mass flow transducer is ideal for economical monitoring of clean air flows in ducts and pipes, while producing very little permanent pressure drop in the flowstream The FMA-900 employs two rugged glass-coated RTD elements, protected by a 1⁄4" diameter 304SS tube with a“window” cut out. One RTD is the velocity sensor, while the other RTD provides ambient air temperature compensation. The velocity sensor is heated to maintain a constant (approximately 30°C) temperature differential above the ambient air temperature, as measured by the second RTD element. The cooling effect of the air flow experienced by the velocity sensor is measured and converted to an electrical output signal proportional to air velocity. The FMA-900 is provided with a 13" long probe as standard. The 304SS tubing is provided with inch marks for ease of insertion depth.UnpackingThe following items are supplied with the FMA-900:•FMA-900 Series Air Velocity Transducer •Mating connector•Removable plastic protective cover (supplied on the sensor tip)•Operator’s manual1-1Important Considerations Before Installationintrinsically safe. Do not use for flammable or hazardous gases, or inhazardous areas.The FMA-900 air velocity transducer is intended for use with clean air or !nitrogen ONLY. Do not use with other gases, as other gases will produce anuncalibrated, non-linear output signal. In addition, air carrying dust or oil (suchas found in blower/compressor systems that utilize oil) can lead to coating of thesensor and thus, inaccurate readings. Refer to the Maintenance section for moreinformation on cleaning the sensor.The FMA-900 is a bi-directional device; flow in the forward or reverse directionprovides the same output.Installing the FlowmeterThe FMA-900 air velocity transducer can be mounted vertically or horizontallywithout shift in calibration.1.Remove the plastic protective cap from the sensor tip.2.Run a length of straight pipe before and after the flowmeter. The amount ofupstream straight pipe run required depends upon the type of obstruction whichis immediately upstream of the flow sensor. See Table 2-1 for specificrequirements. Downstream of the flow sensor, in all situations, run 5 diametersof straight pipe, regardless of the downstream obstruction.3.Align the FMA-900 with the air flow. Make sure the width of the electronics box(2 inches) is parallel with the flow stream.The score line on the tubing is another way of aligning the air flow sensor withthe flow stream. The score line starts from the center of the transducer windowand as a result it can be aligned properly.One means of installing the probe into a flow stream is to utilize a compressionfitting, such as OMEGA’s SSLK-14-14 stainless steel compression fitting withTeflon ferrules, which permits adjustment of the insertion depth of the probe.On Remote Probe Models (-R), connect the remote probe cable to the ElectronicHousing.1-2Table 2-1 Piping Requirements1-3Wiring the Flowmeter1.Connect pins as follows:PLUG PIN NO.DESCRIPTION1 0-5 Vdc or 4-20 mA Output (−)2 0-5 Vdc or 4-20 mA Output (+)3Power Supply (+)4No Connection5No Connection6Power Supply (−)2.Blow clean air through the FMA-900.3.Install the sensor into the pipe or duct.Measuring Air FlowThe FMA-900 measures standard velocity, which is the mass velocity of the airreferenced to 25°C and 760 mm Hg. No temperature or pressure corrections arerequired. Where SCFM (standard cubic feet per minute) measurements aredesired:1.Locate the point of average velocity in the pipe or duct.2.In round pipes, under turbulent flow conditions (where the Reynolds number isgreater than 5,000), mount the velocity sensor approximately 1⁄8of a pipediameter in from the the pipe wall. For example, in an 8" diameter pipe, mountthe probe 1" in from the pipe wall.3.For pipes or ducts where the flow is not turbulent, or the flow profile is notsymmetrical (due to inadequate straight pipe runs, etc.), perform a traverse ofthe duct, in accordance with standard duct traversal methods as recommendedby ASHRAE or the National Air Balance Council.4.To obtain SCFM, once the probe is mounted in the location of average velocity,multiply the average velocity readings (in SFPM, standard feet per minute) bythe cross-sectional area of the pipe or duct, in square feet. For standard pipe,these values can be found in the technical section of the OMEGA CompleteFlow and Level Measurement Handbook and Encyclopedia®. MaintenanceExcept for intermittent removal of the sensor from the line for cleaning, there isno routine maintenance for the FMA-900. If the probe becomes coated with dust,blow the dust away with clean air. If the probe is coated with sticky material,clean it with a solvent which is compatible with epoxy, glass, and 304SS, andwhich will not leave a residue on the sensor. You may clean the sensor withwater or alcohol (Ethanol) and an artist’s brush.CalibrationEach FMA-900 is individually calibrated in a NIST-traceable wind tunnel. Forcalibration certification or calibrating to a new range, the unit must be returnedto OMEGA.

While using full-duplex mode, only peer-to-peer operation is available. For work in multi-point operation, half-duplex is the only choice.While working in full-duplex mode, one of the two com-munication modules is set as master and the other is set as slave. And both modules have same baudrate, frequency and channel select.While working in half-duplex mode, the all modules have the same configuration. The baudrate and frequency select need all the same, and all modules select slave mode. The channel se-lect is invalid for half-duplex mode. In half-duplex mode, only one module may transimit at the same time. If more than one mod-ule transimit data at the same time, the received data is not correct.2.2 Synchronous and AsynchronousIn synchronous mode is that the serial data need to specificed format, 1 start bit, 8 data bits, no parity bit and 1 stop bit.The data is readed in fixed data format and transimt. The re-ceiver receive the data and output the data in fixed data format.In asynchronous mode, the data is sampled and then transimit. And the receiver received data and regenerate the data by the sampled data. For the limitation of sampling rate of 32KHz, the data rate is limited to 14.4Kbps in order to prevent the distor-tion of the output data. While using asynchronous mode, only RS-232 interface may work.2.3 Configuration SelectThere are 3 different configuration of SST-900 and SST-2400 modules.Operation Mode 1 : Full-duplex, SynchronousPeer-to-peer communicationOne master configuration and one slave configurationMax baudrate : 19200bpsFixed data format : 1-bit start, 8-bit data, no parity, 1-bit stop Operation Mode 2 : Half-duplex, SynchronousMultiple nodescommunicationAll slave configurationMax baudrate : 57600bpsFixed data format : 1-bit start, 8-bit data, no parity, 1-bit stop Delay between transimit and receiveChannel select is disabledOperation Mode 3 : Full-duplex, AsynchronousPeer-to-peerOne master configuration and one slave configurationMax baudrate : 14400bpsV ariable data formatRS-232 interface only2.4 Operation Mode 1Operation mode 1 is full-duplex, synchronous, fixed data format communication configuration. The mode is the most com-mon mode for peer-to-peer communication. This mode may en-code the input data streams and transimit to the other SST modules. And the other modules may decode the data streams and put into serial communication line. This may decrease the communication error rate and increase the communication stability.Jumper Seeting : Refer Sec.1.4 for detail(1) : Select one channel(2) : Select one frequency(3) : Select one baudrate, max 19200 bps(4) : Full-duplex(5) : Select master or slave(6) : Synchronous(7) : RS-232 or RS-485Benefits :1.Most stable communication2.Full-duplex communicationLimitation :1.Fixed data format2.Peer-to-peer only3.Baudrates up to 19200 bpsOperation mode 2 is half-duplex, synchronous, fixed data format communication configuration. This mode may operate for communication with two or more SST modules. While operation in this mode, all SST modules are virtually connect together with an invisible line. All communication data broadcast to every SST module. The mode is suitable to build a wireless communication network with max baudrate 57600bps. For the fewer error correc-tion mechanism, the mode may have more communication error than operation mode 1.Jumper Seeting : Refer Sec.1.4 for detail(1) : Channel select is useless(2) : Select one frequency(3) : Select one baudrate(4) : Half-duplex(5) : Slave(6) : Synchronous(7) : RS-232 or RS-485Benefits :1.Multiple nodes communication2.Baudrates up to 57600 bpsLimitation :1.Fixed data format2.Half-duplex onlyOperation mode 3 is full-duplex, asynchronous commu-nication configuration. This mode is work by the way of sample and rebuild. The SST module samples the serial input (RX of RS-232) and transimit to the other SST module, and receive from RF to rebuild the serial output (TX of RS-232). For the limitation of sampling rate, the data waveform may be distorition for higher data rate.Jumper Seeting : Refer Sec.1.4 for detail(1) : Channel select is useless(2) : Select one frequency(3) : Baudrate select is useless(4) : Full-duplex(5) : Select master or slave(6) : Asynchronous(7) : RS-232Benefits :1.Full-duplex communication2.Variable data formatsLimitation :1.Peer-to-peer only2.Baudrates up to 14400 bps3.RS-232 interface only3 Application3.1 Peer-to-Peer CommunicationSST-900/2400 Configuration :Interface : RS-232Operation Mode 1 :Full-duplex Synchronous MasterBaudrate : 19200bps maxSST-900/2400 Configuration :Interface : RS-232Operation Mode 1 :Full-duplex SynchronousSlaveBaudrate : 19200bps maxNote : Basic full-duplex com-munication application for data format is 1-8-1 mode.

Binary B-900 Series Media over IP 系统网络指南说明书

2This guide details the networking requirements, recommendations and limitations whenconfiguring a Binary B-900 Series Media over IP system (MoIP) system which can be used to deploy MoIP on any compatible network switch. Also, you will find the simple steps to configure an Araknis 210 Series PoE and 310 Series PoE Layer 2 managed switch in a single switch MoIP deployment as well as basic guidelines, requirements for single and multiple switch MoIPsetups.IMPORTANT: Network switches directly connected to MoIP Transmitters and MoIP Receivers should always be configured prior to connecting any of these components.Single Switch DeploymentsMultiple Switch DeploymentsAraknis switches do NOT support multiple switch setups at this time. SnapAV does notrecommend a particular switch as an alternative to Araknis. In setups where MoIP transmitters and MoIP receivers must be connected on multiple extended switches, multiple gigabit uplinks between switches is required. Numerous network switch manufacturers offer switches with multiple gigabit uplink/SFP ports to support multiple switch deployments.SELECTING A NETWORK SWITCHNetwork Switch RequirementsThe Ethernet PoE switch selected is critical for the optimal performance of the MoIP system.Araknis 210 Series and 310 Series PoE switches are recommended. Switch functionality,capability and reliability can vary greatly from one manufacturer to the next. Configuration will vary by manufacturer. Refer to the manufacturers user manual to enable required features to support MoIP. Some brands of switches may have limited support of required functions,bandwidth across the entire switch, and necessary total PoE power to support all MoIPTransmitters and Receivers.3Network Switch Minimum RequirementsA network switch selected for a MoIP system must meet the requirements below or supportthe following features:Single Switch Deployments• Layer 2 or Layer 3 Managed• 1 Gigabit Ethernet Port Throughput (minimum)• Simultaneous 7.5 Watts PoE across all ports (minimum)• Multicast forwarding or filtering• IGMP Snooping• IGMP Querier• IGMP Snooping Fast Leave• Also known as Instant Leave or Immediate Leave• Jumbo Frames (8000 bytes or larger)• Also known as Jumbo Packets or Maximum Transmission UnitIf a multiple switch deployment is required, the switches must also support:• Dynamic Multicast Router Port• Forwarding Unknown Multicast to Multicast Router Port OnlyNote: It is highly recommended that the above features be applied to all network switches on the same LAN as MoIP as a best practice. This is not required; however, highly recommended. Number of PortsGiven the flexibility and scalability of Binary’s B-900 Series Media over IP system, it isrecommended that a switch with more Ethernet ports than needed for the MoIP system be used to allow quick addition of devices in the future. Utilizing an Araknis 210 Series 48-port PoE switch, a MoIP system maximum size limit is 47 total MoIP Transmitters and MoIPReceivers. Larger systems utilizing other manufacturer’s switch is possible in both single and multiple switch deployments.When calculating the size of switch needed, count one port for each the following devices:1. Number of sources (MoIP Transmitters)2. Number of displays (MoIP Receivers)3. MoIP Controller4. LAN connection to main network for OvrC (if applicable)PowerThe MoIP Transmitters and MoIP Receivers can be powered by Power-over-Ethernet (PoE) or a separate 12V power supply (not included). The separate power supply is available only as a replacement part only. TX and RX will each utilize no more than 7.5 watt of power. Snap AV recommends using PoE to power the MoIP TX and RX units. The MoIP Controller is NOT powered by PoE and requires the use of the included 12V power supply.4MoIP System Network SetupsSingle switch MoIP network configurations are supported by Araknis 210 PoE and 310 PoE Series switches. Integrators familiar with the above requirements and the configuration of stackable and cascaded switches with multi-gigabit uplinks will be able to create very large MoIP deployments.Single SwitchDedicated MoIP Switch (RECOMMENDED)Shared MoIP SwitchMoIP on Main LAN SwitchMultiple SwitchesPlease refer to your network switch manufacturers’ documentation to enable the criticalfeatures for optimal performance in multiple switch MoIP network configurations.Bandwidth considerations are critically important. The maximum number of MoIPTransmitters which can be supported by a given network topology is limited by the lowestbandwidth link in the network. Typically, this will be the link between switches. MoIP Receivers5have no impact on available bandwidth. The bandwidth requirements of other devices on the network should also be considered.Each MoIP Transmitter will consume 250-850 Mbps (4K) or 150-750 Mbps (1080p) ofthe available bandwidth. The lowest bandwidth link limitation applies no matter to which switch in the multiple switch setup the transmitter is connected. To calculate the required bandwidth needed to support the desired number of MoIP Transmitters, multiply the number of MoIP Transmitters by 0.85. This will give you the bandwidth in Gbps. For example, 10 MoIP transmitters would require 8.5 Gbps. In the diagrams below, X Gbps indicates a multiple gigabit connection between switches. The throughput of this uplink must accommodate, for this example, 8.5 Gbps for the MoIP system to operate optimally.Cascaded SwitchesStacked Switches671. Configure Network SwitchSteps below use an Araknis 210 PoE or 310 PoE Series switch as an example1. F actory default the MoIP switch to be used for all MoIP Components (not necessary for new switches). Press and hold the reset button for 10—15 seconds until the Status LED flashes once. This will reboot the switch and reset to factory settings.2. C onnect the dedicated MoIP switch directly to your Main LAN switch . (The Main LAN switch is the main network switch into which all other switches and network devices are connected. The Main LAN switch is the only switch connected to the router. A dedicated MoIP switch is preferred but not required. See ‘Network Guide’ for more information.)3.

Alpha·Omega 900 产品说明书

The Alpha·Omega 900 takes the best elements of our most successful distortion preampliﬁer ever, combined with state-of-the-art features to make a monstrous 900-wattampliﬁer with earth-shattering tone.While our signature Alpha·Omega® drive engines and incredible girth and size to the overdriven signal, the studio-grade VCA compressor adds an extra layer of control, and the ultra-quiet 6-band graphic equalizer can help sculpt the tone in any way necessary, as well as providing a wide variety crystal clear clean sounds.But that is not everything: the MIDI programmability and impulse response cabinet simulation with up to three different storable virtual cabinets make the AO900 not only one of the most complete ampliﬁers for the touring musician but, combined with the auxiliary input and headphone output, the ideal tool for silent practicing. OR but also the ideal tool for silent practicing, when combined with theauxiliary input and headphone output.The Alpha·Omega 900 ampliﬁes the best qualities of one of the most powerful anddistinct Darkglass® pedals ever made.The Alpha·Omega 900 is a 900W ampliﬁer equipped with an all-analog preampliﬁer, Class D Power Module and a digital impulse based cabinet emulator for DI outputs or headphones. Probably the ﬁrst thing you will notice from the Alpha·Omega 900 is its unusual control layout: On the right side you’ll ﬁnd the clean section which is the foundation of your sound.It features Gain and Master volumes and active 6 band graphic EQ. Along with the mandatory Low and Treble controls you will ﬁnd 250Hz, 500Hz, 1.5K Hz, 3K Hz sliders. Character is all in the midrange. Having 4 dedicated Mid controls allows you to cover the whole mid range (250Hz to 3kHz) to have total control and ﬂexibility over the ampliﬁer’s character. On the left side, by the input jack you will ﬁnd the Alpha·Omega Engine which acts as an extra channel. This creation differs greatly from our previous preampliﬁers and overdrives: its operational-ampliﬁer topology featuring two distinct distortion circuits (Alpha and Omega), which can be selected or blended using our Mod knob, make the Alpha · Omega® the most ﬂexible among our designs. DESCRIPTIONThe Alpha·Omega Engine can be engaged via the front panel or via our own digitally controlled (jack on rear panel). Besides engaging the Alpha·Omega circuitry you can hold the actuator to Mute the ampliﬁer. The Intelligent Footswitch is housed in an elegant, laser-engraved unibody chassis and requires a standard ¼” mono cable (not included) for it’s full operation.Besides this incredibly versatile preampliﬁer, we equipped the power module with some unique control over the power output and minimum speaker loads:The standard mode will deliver 900W RMS at 4Ω/500W at 8Ω. If you select the 2Ω Mode via the rear-panel switch the ampliﬁer will deliver 900W at 2Ω/500W at 4Ωand 350W at 8Ω.This deceivingly simple feature allows for maximum power adaptability: Regardless of the cabinet conﬁguration or power requirements, the Alpha· Omega 900 will deliver accordingly.FEATURES FRONT PANELINPUT : Use this jack to connect your instrument via a standard ¼” mono cable.PASSIVE/ACTIVE : Use this push-button switch to change from passive to active mode. If your bass is active it can have a hotter signal making the amp to distort early (feel free to use if such additional distortion is desired).DISTORTION: Use this push button to turn on or off theAlpha·Omega Engine to add natural compression, organic harmonic enhancement, and saturation ranging from mild overdrive to high gain bass rage.The Alpha·Omega Engine operates before the clean section (you can therefore use the 6-Band Active EQ for additional tone shaping).BITE: Boosts high mids (2.8kHz) for additional presence and deﬁnition.GROWL: Shelving Bass Boost for a fatter tone and increased low end saturation.COMPRESSION: This knob controls the amount of dynamic compression added to the Alpha·Omega Engine. The make up gain is adjusted automatically. The compression can be turned off or assigned using the Darkglass Suite.DRIVE : This knob controls the amount of distortion that the Alpha·Omega Engine will deliver. It will change from a soft, warm overdrive to a massive and modern distortion sound.LEVEL : Use this knob to control Alpha·Omega Engine’s output volume.BLEND : Use this knob to mix between the Clean signal and the DIstortion signal (Alpha·Omega Engine). MOD: Selects or mixes between the two distinct distortion circuits: Alpha is punchy, tight with a lot of deﬁnition, whereas Omega is simply brutal and raw. GAIN : Use this knob to change the volume of the signal before the Active 4 Band EQ. You can set it low for ensuring the cleanest operation possible or set it higher for a more aggressive growl.BASS : +-12dB at 80Hz. Use this knob to change the low-end content of the signal.MIDS: +-12dB at 250, 500, 1.5K and 3K hz. This graphic EQ control the mid content of the signal.TREBLE : +-12dB at 5kHz. Use this knob to change the high content of the signal.MASTER : Use this knob to control the overall volume of the ampliﬁer.MUTE : Use this push button to mute the ampliﬁer.FEATURES REAR PANELSPEAKER OUTPUT : Use this connector to connect the ampliﬁer to your cabinet. This Speakon combo jack allows for either Speakon or ¼” speaker cable operation. The outputs are connected in parallel.WARNING: Do not use an instrument cable with this ack. Using an instrument cable can damage your ampliﬁer.4Ω / 2Ω : Press this switch when using a 2Ω load. You can use this control to lower the output if your 4Ωcabinet is not able handle more than 500W (you can also get 350W with an 8Ω cabinet in this conﬁguration).SEND : Use this output to send the signal to effects pedals.RETURN : Use this input to receive the signal from effects pedals. Master volume control is after this input.GROUND LIFT : Use this control to lift the ground of theDI XLR outputs. If you are experiencing ground noise in your DI signal try changing the setting of this control.PRE DI OUTPUT: Use this output to send a balanced copy of your input signal to recording equipment, mixer, etc. The output is latency compensated to match with the Post DI Output.POST DI OUTPUT: The signal for this output is taken afterthe distortion, EQ and effects loop, and processed through the cabinet simulation engine. The output is latency compensated with the Pre DI Output, and not affected by the master volume.USB: The USB connector allows you to connect the ampliﬁer to Darkglass Suite (PC/Mac, /suite). Darkglass Suite offersﬁrmware updates, a selection of cabinet impulse responses, and allows you to control various parameters on the ampliﬁer, such as enabling the compressor for speciﬁc channels, MIDI settings, etc.HEADPHONE OUTPUT: Connect your Headphones and enjoy the impulse response cabinet emulation.HEADPHONE VOLUME: Controls the volume of the headphone output.AUX IN: Use this connector to provide to the Headphone output music from your laptop, cellphone, mp3 player, etc.CAB SELECT: Switches between 3 different cabinet impulses and bypass this section for a rawer sound.MIDI: The MIDI input allows you to control the following settings with any MIDI standard controller: Channel, Mute, Impulse slot, Compressor on/off. Settings can be controlled with Control and Parameter Changes.FOOTSWITCH : The Intelligent Footswitch is a proprietary digitally controlled device that allows you to remotely engage and disengage the Alpha·Omega Engine.

Connection diagram and basic conditionConceptFigure 1 illustrates the connection diagram used in the demo to use the Keysight B2900A Series SMU as an ammeter. Since the current polarity of the SMU is opposite to an ammeter, the Low Force terminal of the channel has to be connected to the current output port of the device under test (DUT).In this demo, a 1.1 kΩ resistor combined with a power supply is used as a DUT, a current source circuit. The channel 2 of the B2902A/12A is used as a power supply. However, you can also use your own power supply for it.Setup1. Connect the yellow banana plug of the 11059A to the Ch 1 Low Force Terminal.2. Connect the red banana plug of the 11059A to the Ch1 High Force Terminal.3. Clip the end of the 1.1 kΩ resistor with the black gold-plated tweezers of the 11059A.4. Connect the black banana cable of the U8201A to the Ch2 Low Force Terminal.5. Connect the red banana cable of the U8201A to the Ch2 High Force Terminal.6. Clip the other end of the 1.1 kΩ resistor with the red alligator clip of the U8201A7. Connect the red gold-plated tweezers of the 11059A to the black alligator clip of the U8201A.LAB1: Use Source/Measure Unit as an AmmeterObjectiveThis demo illustrates the current mea-surement function as an ammeter by sourcing 0 V voltage and measuring the current from the resistor biased by a power supply using a Source/Measure Unit.Procedure1. Configure the low terminal state to FLOATING2. Measure current using the SMU (Channel 1) as an ammeter3. Enable the DUT, the current soure circuit4. Confirm measured current5. (Optional) Configuring the measurement speed6. (Optional) Configuring the measurement range operationDemonstrationIn the default setting, the low terminal of the channels in the Keysight B2900A Series SMU is grounded internally. However, the low terminal can be disconnected from the ground and kept floating. Configur -ing the low terminal state to FLOATING, which enables you to connect the low terminal to any potential up to ±250 V, and measuring current with sourcing 0 V from the channel, which makes it possible to use the channel as an ammeter.1. Configure the low terminal state to FLOATING1) If you aren’t on the top of the Function menu, press repeatedly to return to the top level.2) Press , , and then press to open the Output Connection dialogue.3) Press and select to specify the channel which the Low terminal state is configured for.In the middle level of the Function menu(1) Press Config (2) Press Source (3) Press Connection4) Press and select , and then press to configure the Low terminal state to FLOATING .If the low terminal state of the channel is set to FLOATING, you can see the status indicator on the GUI as below, although no indicator can be seen on being set to GROUNDED.2. Measure current using the SMU (Channel 1) as a ammeter2-1. Change View mode to Ch1 Single View 1) Press repeatedly until the Channel 1 Single View is displayed2-2. Configure the condition to source and measure1) Press to edit the Source function , and then select to set the Source function to Voltage source.GROUNDEDFLOATING2) Press to edit the Source value , and then enter 0 V to set the Source value to 0 V .3) Press to edit the Limit value , and then enter 100 mA to set the Limit value to 100 mA for example.4) Press to configure the Measurement parameter , and then select to set the Measurement parameter to Current .5) Rotate and press to edit the Voltage source range operation . Then Select to set the Voltage source range operation to FIXED .6) Rotate and press to edit the Voltage source range , and then select to set it to 200 mV .2-3. Perform the measurement1) Press for the channel 1 to switch on its output terminal.2) Press to perform a measurement repeatedly. Now you can see the measurement result on the GUI of the B2902/12A as below.3. Enable the DUT, the current source circuitYou can also use your own power supply instead of the channel 2 of the B2902A/12A3-1. Change View mode to Ch2 Single View.1) Press repeatedly until the Channel 2 Single View is displayed.3-2. Configure the condition of the power supply (Channel 2)1) Press to edit the Source function , and then select to set the Source function to Voltage source.2) Press to edit the Source value , and then enter 1.1 V to set the Source value to 1.1 V for example.3) Press to edit the Limit value , and then enter 100 mA to set the Limit value to 100 mA for example.4) Press for the channel 2 to switch on its output terminal and enable the DUT.4. Confirm measured current4-1. Change View mode to Ch1 Single View.1) Press repeatedly until Channel 1 Single View is displayed.You can see about 1 mA as measured value, since 1 V is sourced to a 1.1 kΩ resistor. If you press for the channel 2 to switch it off, you can see only the offset current because the DUT, the current source circuit is disabled.Theoretically speaking, the measured current should be 1 mA since 1.1 V is sourced to a 1.1 kΩ resistor. However, it may be varied because the resistor has some error onits value actually.Power Supply enabled Power Supply disabled5. (Optional) Configuring the measurement speedIn the default setting, the instrument selects the appropriate measurement speed and range automatically to get the fine accuracy. However, you can also specify these parameters on the GUI of the B2900A Series SMU to meet a variety of the requirement to the measurement conditions.For example, let’s try to change the measurement speed to NORMAL to make a mea-surement more carefully. If you select NORMAL, the aperture time is set to 1 PLC. Here, PLC stands for power line cycle and the specified number of power line cycles is used per a measurement.1) Press to edit the Measurement speed, and then select to set theMeasurement speed to NORMAL. (If you can’t see in Assist keys, pressto change the keys shown in Assist keys.)6. (Optional) Configuring the measurement range operationThe parameters which configure the measurement range operation can be displayed in the Range Sub-panel in the Channel 1 Single View. In the default setting, the B2900A Series SMU performs the current measurement using a 1 μA current minimum measure-ment range with AUTO range operation. With AUTO range operation, the B2900A Series SMU selects the proper range for the measurement with the specified minimum mea-surement range so that you don’t need to take care about it. To know how to change the measurement range setting, try to configure to use the 10 μA current minimum mea-surement range with AUTO range operation.1) Rotate and press to edit the Current minimum measurement range and thenselect to set it to 10 μA.If you’d like to fix the measurement range, you can select FIXED range operation as below.2) Rotate and press to edit the Current measurement range operation. ThenSelect to set the Current measurement range operation to FIXED.ConclusionThe Keysight B2900A Series Precision Source/Measure Unit (SMU) is a compact and cost-effective bench-top SMU with the capability to output and measure both voltage and current. Although it has the capability to make a wide range of current versus voltage (IV) measurements as its intrinsic function, the B2900A Series SMU can be used as an ammeter easily.B2900 Precision Instrument FamilyThe B2900 family contains products that perform both precision sourcing andprecision measurement. /find/b2900amyKeysight/find/mykeysightA personalized view into the information most relevant to you.Keysight Infoline/find/InfolineKeysight’s insight to best in class information management.

Honeywell HC900 Hybrid Controller产品说明书

HC900 Hybrid ControllerWhen you need more than just discrete controlProduct Note - Positional Proportional OutputBackground:Many processes under control today have requirements that are best satisfied using energy regulating devices that are directly connected to electromechanical motor actuators. Electromechanical actuators have been in use in industry for control system regulation for more than 50 years, and there is a large installed base of these devices. Many control system upgrade projects focus on the electronic hardware located in the control room, but fail to include motor actuators in the project, particularly if they are functioning acceptably. Although newer “Smart” actuators can offer numerous maintenance and asset management advantages, they are often overlooked when upgrade projects are planned.The motor actuator used for regulation uses a bi-directional motor that holds its last position when deactivated. Many actuators use a position sensing device to provide a signal to the control system of the actual actuator position. One of the most common sensors used for this function, because of its low cost, simple design and rugged performance, is a variable resistor or slidewire. Since the slidewire is a passive electronic device, one of the requirements of the control system is to provide an excitation voltage in order to obtain a position output signal. Although the slidewire is a cost effective and rugged device, it does have a mechanical attribute that is subject to wear over time. For this reason, some actuator suppliers offer electronic position sensors that can supply a voltage or current without the dependency on wear component hardware. For these devices, control systems typically only require a high level analog measurement capability and an algorithm to position the motor. Algorithms used to position actuators with feedback sensors do not have a standard terminology for their identification but a few of the most common names used are: Position Proportional Outputs (PPO), Position Adjusting Type (PAT), and Motor Positioner (MP). Honeywell uses the PPO terminology.When knowing the actual motor position in a control system is not important, many actuators are supplied without a position sensor. The control systems used to regulate these actuators depend on a special algorithm that simulates an internal feedback to substitute for the actual feedback signal. The most commonly recognized algorithm for this type of control is the “Three-Position-Step” algorithm.Both the Position Proportional Output (PPO) and the Three Position Step Control (TPSC) can provide excellent process control when properly engineered into the control system.Problem Statement:Many first time application engineers approach position proportional control as a very simple task. Just measure the analog signal representing position, compare it to the desired position, and if the value is lower than required, turn a digitaloutput ON to increase the position, and if the value is too high, turn the decreasing output ON. To keep the motor from oscillating, add some dead-band, or said another way, compromise position accuracy to improve motor life. This is typically not more than a few program statements in a PLC.Before putting the system on-line the following problems must be addressed:1. The passive slidewire position sensor of the actuator requires electrical excitation, (typically DC power source with avoltage low enough not to cause the resistive element to heat up or burn out). If the controller does not provide this voltage, an external power supply must be used.Once on-line, other problems surface:2. Once the slidewire is powered and the actuator is moved to its 0% and 100% travel limits based on the setting of themotor limit switches, a common observation is that the limit switches stop the motor before the slidewire contact reaches its 0% and 100% voltage limits. If the power supply used to excite the slidewire was 5 volts, the feedback voltage measured between 0% and 100% may typically be between ~0.3V and ~4.8V. A measurement of feedback based on a 5V span would have an error of 0.5V or a 10% error. To correct this error the actual span value of the feedback signal as measured on a 5V analog input range must be re-spanned to have 0.3V and 4.8V represent 0% and 100% travel of the motor.3. Once the feedback is addressed, positioning the motor becomes the next issue. If a simple compare algorithm isused to determine when to increase or decrease the motor, an oscillation of the motor is guaranteed. This is because it takes time to measure the analog feedback, process the compare function, and turn an output OFF. During this time the motor is still moving. When the motor is finally deactivated, it will have already passed the compare point that initiated the action to turn off. The amount of overshoot is based on the algorithm processing time and motor speed. Also, if the update rate of the algorithm is not consistent or varies with processor loading, the amount of overshoot will also vary.To avoid this overshoot condition, a timed output approach is typically used to position the motor. With this approach, if a 15 second motor is at its 0% position and a new request comes in for a 50% position, the output algorithm would turn ON its output for 7.5 seconds. This feature adds a new complexity, to measure the time for full scale motor travel and use this value in the output algorithm calculation.4. Another variable that must be considered is the amount of motor over-travel that may occur after power to the motor isremoved. To minimize this condition, many actuators employ a gearing or braking system, but it can seldom be reduced to zero. To optimize control of this variable, a combination of timed pulses and a dead-band are typically used.When fully implemented the final program often requires significantly more work than initially planned. The Solution:The HC900 “Position Proportional Output” (PPO)The HC900 Position Proportional Output is designed to provide optimum actuator position control with a minimum of setup complexity. From a standard analog input range for feedback slidewire measurements to a fully automatic feedbackcalibration feature, the HC900 PPO algorithm excels. Once on-line, the PPO algorithm provides additional benefits with a scaled output of the actual motor position that may be used on displays or integrated into the control strategy, and diagnostics routines that run in the background that detect actuator problems. The following are a few of the HC900 PPO algorithm highlights and benefits.1. Standard analog ranges embedded in the PPO algorithm to measure slidewire resistances between 100 and 1000ohms. (No external power supply required. Uses a simple 3-wire connection to the standard universal AI module.) Voltage ranges of 0 to 5V, 0 to 1V, and current ranges 0 to 20mA , 4 to 20mA are also supported for feedback inputs.2. Flexibility to use any type of digital output module with the PPO algorithm, AC, DC or Relay. (No special outputmodules or incompatible voltages.)3. Complete actuator control setup from a single PPO function block including analog input hardware and range, digitaloutput hardware, actuator feedback scaling and motor speed, actuator sensitivity (dead-band). ( Easy to setup, easy to troubleshoot.)4. Fully automatic feedback signal calibration. Scales the actual feedback signal values to represent 0 to 100% outputand calculates motor speed. (The easy choice for easy to use.)5. Semi-automatic feedback calibration (user initiated step-by-step process) and manual feedback calibration (usermanually moves the motor) also supported. (Offers flexibility when required.)6. User entered dead-band support for values from 0.5% to +/- 5.0%. Ideal for actuators without braking action.7. Input scaling support is included to allow reverse scaling for heating/cooling applications using Duplex control (0 to 50,50 to 0).8. User entered output limit values supported. For users who want to limit actual actuator travel to values less than 0and 100%.9. Actuator position output pin provided for displays or connection to other function blocks.10. Feedback failure detect output pin provided. Digital output turns ON if the algorithm detects a failed slidewire.11. Automatically defaults to Three-Position–Step control on feedback failure.12. Fault output pin turns ON upon detection of a failed or stalled motor.The HC900 controller can support up 64 PPO algorithms, or two for each PID loop. The algorithms also execute independently from the PID algorithms, allowing them to accept setpoint signals from other sources. For example, a single manually entered variable from an OI overview display could be used to set the position of multiple actuators simultaneously. Another application might connect two actuators to the same PID algorithm with the actuators operating in series, applying unique input scaling to each actuator. These are only a few examples of the control flexibility afforded users with the HC900 PPO algorithm.How to Order:The PPO algorithm is offered in the HC900 controller at no additional cost in CPU versions 900C51-0011, 900C52-0011, 900C31-0011, 900C32-0011 and later versions. If direct slidewire measurements are required, analog input module 900A01-0002 is required. This module is a direct replacement for module 900A01-0001 in all applications.Use the HC900 PPO algorithm in retrofit applications and in new applications when accurate positioning of drive actuators is required.Typical Position Proportional Configuration and Wiring:Analog Input Module AC Output Module。
