一个电路通常由电源、开关设备、用电设备和连接线四个部分组成，如果将电源设备、开关设备和用电设备看成元件，则电路由元件与连接线组成，或者说各种元件按照一定的次序用连接线起来就构成一个电路。
可编程控制器的定义可编程控制器，简称PLC（Programmable logic Controller）,是指以计算机技术为基础的新型工业控制装置。
PLC的特点1可靠性高，抗干扰能力强高可靠性是电气控制设备的关键性能。
PLC由于采用现代大规模集成电路技术，采用严格的生产工艺制造，内部电路采取了先进的抗干扰技术，具有很高的可靠性。
例如三菱公司生产的F系列PLC平均无故障时间高达30万小时。
一些使用冗余CPU的PLC的平均无故障工作时间则更长。
从PLC的机外电路来说，使用PLC 构成控制系统，和同等规模的继电接触器系统相比，电气接线及开关接点已减少到数百甚至数千分之一，故障也就大大降低。
2配套齐全，功能完善适用性强PLC发展到今天，已经形成了大、中、小各种规模的系列化产品。
可以用于各种规模的工业控制场合。
除了逻辑处理功能以外，现代PLC大多具有完善的数据运算能力，可用于各种数字控制领域。
近年来PLC的功能单元大量涌现，使PLC 渗透到了位置控制、温度控制、CNC等各种工业控制中。
加上PLC通信能力的增强及人机界面技术的发展，使用PLC组成各种控制系统变得非常容易。

A small pencil type soldering iron of 25 - 40 watts is recommended.The tip of the iron must be kept clean at all times and well tinned.Safety Procedures•Wear eye protection when soldering.•Locate soldering iron in an area where you do not have to go around it or reach over it.•Do not hold solder in your mouth.Solder contains lead and is a toxic substance.Wash your hands thoroughly after handling solder.•Be sure that there is adequate ventilation present.Assemble ComponentsIn all of the following assembly steps, the components must be installed on the top side of the PC board unless otherwise indicated.The top legend shows where each component goes.The leads pass through the corresponding holes in the board and are soldered on the foil e only rosin core solder of 63/37 alloy.DO NOT USE ACID CORE SOLDER!Solder Soldering IronFoilSolder Soldering IronFoilComponent Lead Circuit BoardFoilRosinSoldering iron positioned incorrectly.SolderGapComponent LeadSolderSoldering IronDragFoil 1.Solder all components from the copper foil side only.Push the soldering iron tip against both the lead and the circuit board foil.2.Apply a small amount of solder to the iron tip.This allows the heat to leave the iron and onto the foil.Immediately apply solder to the opposite side of the connection, away from the iron.Allow the heated component and the circuit foil to melt the solder. 1.Insufficient heat - thesolder will not flow onto the lead as shown.3.Allow the solder to flow around the connection.Then, remove the solder and the iron and let the connection cool.The solder should have flowed smoothly and not lump around the wire lead.4.Here is what a good solder connection looks like.2.Insufficient solder - let thesolder flow over the connection until it is e just enough solder to cover the connection.3.Excessive solder - couldmake connections that you did not intend to between adjacent foil areas or terminals.4.Solder bridges - occurwhen solder runs between circuit paths and creates a short circuit.This is usually caused by using too much solder.To correct this,simply drag your soldering iron across the solder bridge as shown.What Good Soldering Looks LikeA good solder connection should be bright, shiny,smooth, and uniformly flowed over all surfaces.Types of Poor Soldering ConnectionsElectrolytics have a polarity marking indicating the (–) The PC board is marked to show the lead position.Mount the transistor with the flat side as shown on the top legend.Leave 1/4”between the part and PC board.BandD4 -

† UL File XAPX.E108966Fire & Smoke damper actuator ApplicationThe type FSNF spring-return actuator is intended for the operation of smoke and combination fire and smoke dampers in ventilation and air-conditioning systems. The actuator will meet requirements of UL555 and UL555S when tested as an assembly with the damper and will meet requirements of UBC for 15 second opening and closing at 350°F. Square footage of damper operated will depend on make and model and the temperature required.OperationMounting of the actuator to the damper axle shaft or jackshaft (3/8” to 1.05”) is via a cold-weld clamp. Teeth in the clamp and V-bolt dig into the metal of both solid and hollow shafts maintaining a perfect connection. The specially designed clamp will not crush hollow shafts. The bottom end of the actuator is held by an anti-rotation strap or by a stud provided by the damper manufacturer.The actuator is mounted in its fail safe position with the damper blade(s) closed. Upon applying power, the actuator drives the damper to the open position. The internal spring is tensioned at the same time. If the power supply is interrupted, the spring moves the damper back to its fail-safe position.actuators draw higher peak current when driving against any type of stop. If used, this requires the value of a local fuse or breaker to be increased to avoid nuisance opening or tripping. A 2.5 amp slow blow should be used for 24VAC. A 0.5 amp slow blow should be used for 120 VAC. A 0.25 amp slow blowshould be used for 230V and a 0.3 amp slow blow for 208 VAC. Transformers: Note that while a 24V 100VA transformer would handle 2 actuators, a 4 A breaker or plug fuse is insufficient. A 5 amp slow blow would be required.Belimo Fire & Smoke actuators have passed the AMCA 520 and UL 555S Long Term Holding test. No special cycling is required during prolonged periods when actuator is driven open and held there. Periodic testing of dampers and actuators per local codes and NFPA 80 and NFPA 105 are required.The actuator contains no components which the user can replace or repair. A 1/2” threaded connector is standard. FSNFxx-FC models have a 3/8” Flex Connector. Other than the connector, these actuators are identical to the conduit connector version.FSNF120-S USOn/Off, Spring Return, 350°F [177°C] for half hour, 120VAC, 15 Seconds Cycle TimeD a t e c r e a t e d , 12/14/2015 - S u b j e c t t o c h a n g e . © B e l i m o A i r c o n t r o l s (U S A ), I n c .71818-00001Typical SpecificationAll smoke and combination fire and smoke dampers shall be provided with Belimo FSTF, FSLF, FSNF, or FSAF actuators.

艾斯科 BD-50E高频发生器使用说明书
4642 N. RAVENSWOOD, CHICAGO, ILLINOIS 60640-4510TELEPHONE: 1-773-561-2349FAX: 1-773-561-3130Model BD-50E HIGH FREQUENCY GENERATOROPERATING MANUALDESCRIPTION. The Model BD-50E is a rugged tester designed for testing tank lining and other applications where extended use is necessary. The unit is operated by a transformer which limits the current and isolates the unit from the power line for safety protection. The low voltage (magnet coil) and high voltage (resonator coil) are separated, making the unit run cooler than the hand-held models. This also allows for an extended period of use, up to no more than about 3 hours of use, with a similar cool down period.It has a peak output voltage of between 20,000 to 50,000 V, ±2 kV, at a frequency of 0.5 MHz. The current output is approximately 1 mA.The Output Adjustment Knob is graduated from 1 to 11. The actual output voltage will vary depending upon the electrode used, as a larger electrode will load down the unit. Also, there is some variation in output from unit to unit, and will vary depending upon the condition of the vibration contacts inside the unit. Worn contacts will decrease the output. As a rule however, these are the approximate outputs that can be expected from a unit that is operating properly: POSITION N0. 1 3 5 7 9 11 Voltage 20,000 27,000 32,000 38,000 43,000 49,000Four models are available for different input voltages:Model BD-50E (SKU 15001), 115 V, 50/60 Hz, with 12101 Electrode Tip .Model BD-50EV (SKU 15021xx-10), 230 V, 50/60 Hz, with 12101 Electrode Tip. Model BD-50ET Tank Lining Tester Kit (SKU 15031), 115 V, 50/60 Hz, with 12101, 12131, and 12141 Electrode Tips. A carrying case is optional.Model BD-50EV Tank Lining Tester Kit (SKU 15061xx-10), 230 V, 50/60 Hz, with 12101, 12131, and 12141 Electrode Tips. A carrying case is optional.The 115 V model is also available equipped with a power line filter for use around sensitive electronic equipment (SKU 15001-10, and 15031-10).The “V” in the Model Number, BD-50EV, designates a line cord plug for use for 230 V input. The “xx” designates the line cord plug type furnished with models typically used outside of North America. All of these 230 V models are equipped with a power line filter.A 6 ft. (1.8 m) cable from the control box to the high voltage handle is provided with standard, but a longer cable, up to 15 ft. (4.5 m) can be special ordered. Contact Electro-Technic for specific details and ordering information. INSTALLATION. A standard tip electrode, Part No, 12101, illustrated above, but not below is included with each model. To install it, press it into the tip of the generator handle. To remove, grasp its base firmly, and with a gentle twisting motion, pull out from the generator tip. Never insert or remove the electrode while power is on.Accessory Electrodes for the Model BD-50E12111 Spring Tip12121 T-Tip12131 T-Tip, 12 in. Wide12141 Fan Tip12401 Brush Tip4 in. Wide 4 in. Wide12421 Brush Electrode, 8 in. WideThese electrodes, plus the 12101 Standard Tip, are the only factory approved electrodes for the Model BD-50E. No other electrodes should be used.After the electrode is inserted, plug the power line cord into its matching receptacle, providing the proper voltage for the unit, either 115 V or 230 V.OPERATION.1) Turn the Output Adjustment Knob fully counterclockwise, and then turnthe Power Switch to its ON position.2) Turn the Output Adjustment Knob clockwise to adjust the voltage forthe desired spark length. Hold the tip close to the chassis of the unit,or a common ground point, to observe and adjust the length of thespark. For thick materials, the spark should be adjusted for nearmaximum length. For very thin materials, a shorter spark is desired. Aone inch spark represents a peak voltage of approximately 50,000volts.3) When the tip is scanning close to a metal surface, there will be apurple color spark, or corona discharge glow.4) Once the unit is adjusted, pass the electrode over the material beingtested. The electrode can be passed directly over most materials,however, with thin linings, keep the electrode no more than 1/8 in.above the surface being tested.Photo at left shows a pin holelocated in a sheet of rubber,with a metal backing, using the12141 Fan Tip Electrode5) When the electrode passes over a pinhole, crack, or similar type flaw,observe a bright white, concentrated spark jumping from the electrodeto the metal, or similarly conducting surface below the lining or coating.A reprint of an article showing a flaw being detected is included withthese instructions.SAFETY PRECAUTIONS.It is used in industrial applications for pinhole leak detection, and toionize a gas inside a bulb or similar device to determine whether a goodvacuum is being held inside the device. It is also used as a lamp starter,principally in printing industry.Only factory approved electrodes should be used. No other electrodesshould be used with this device. Never operate without an electrode.Never touch or come in contact with the high voltage output of thisdevice, nor with any device it is energizing.Since its output is 500 kHz, it radiates its energy for a short distance.It may interfere with sensitive electronic devices near by. If a user iswearing a pace maker or similar device, their physician should becontacted prior to using this device. The same should be said forwomen who are pregnant.A small amount of ozone gas is generated as a by-product. Use in awell-ventilated area.Do not operate out of doors on in or around a flammable or explosiveenvironment.CALIBRATION SERVICE. Factory calibration service is available for a nominal charge. It includes test data for all output positions with a number of electrodes, and is traceable to a NIST standard. Yearly calibration is recommended. Request a Return Authorization Number prior to returning to the factory for calibration.MAINTENANCE / INSPECTIONS. If the output level of the Model BD-50E is required to be verified when this instrument is in use, check the output with a Model 12701 Peak Voltage Calibrator, shown below.The only component in this equipment that should be checked is the vibrating contacts that make and break the circuitry, generating the high frequency. These contacts, made of a tungsten alloy, erode with use. Eventually, they erode to a point where the output of the unit decreases.If the Model BD-50E receives light duty use, and is otherwise functioning properly, an annual inspection is recommended. If the unit is used on a frequent basis, has been dropped, or the maximum output is found to be decreasing, then a quarterly inspection is warranted.To check the contacts, with the power removed from the unit, remove the cover and visually check the contacts for carbon built-up, burn marks, excessive pitting or erosion. Also check that the contacts are aligned properly.To replace the contacts, remove the magnet coil assembly. Loosen the locking nut and back up the screw all the way back. Remove the top assembly and then remove the top contact and then the bottom contact assembly.Replace the bottom contact assembly, making sure that enough room is left between the bottom contact and the magnet coil top, so that the armature can vibrate freely, with about 0.035 to 0.040 in. clearance.Replace the top contact assembly, making sure that the two contact points will be aligned with each other when they are pushed together.Reinstall the top assembly and then the magnet coil assembly.CAUTION. Take precautions not to touch any wires, as power to beunit will have to be applied with the cover removed to perform thisoperation.To adjust the contacts use a screw driver to turn the adjusting screw to push the contacts until there is a spark between the contacts, the contacts are aligned, and that the armature is vibrating freely.Then tighten the nut, reinstall the screw cap and the cover.Recheck the output with the Model 1270 Peak Voltage Calibrator.If you should have any further questions, contact Electro-Technic Products, Inc. for additional technical assistance.TROUBLESHOOTING AND REPAIR. There are no user serviceable parts inside the unit. In the event that the unit requires service, send it back to the factory. However, parts are available separately, so an experienced electronics technician can make repairs. The following troubleshooting guide is furnished: Check all connections for loose or broken wires. If the pilot light does not come on, check for shorts and for input voltage at the fuse. If fuse is blown, replace it with a 3/4 A Slo-Blo for 115 V units, and ½ A Slo-Blo for 230 V units.If the fuse is Okay, check the power cord for shorts, and replace if necessary. Test the ON/OFF Switch.If the pilot light comes on, check the transformer for voltage between the secondary leads. If voltage is Okay, then check the magnet coil for resistance between 65 to 72 ohms for 115 V units, and 262 to 270 ohms for 230 V units. Check the contacts for the presence of a spark. If no spark, move the adjusting screw clockwise or counterclockwise. If the spark comes on, the unit is Okay. If not, check the printer circuit board for shorts and clean the contacts at the positions of the switch. If this does not solve the problem, replace the board. If the contacts of the magnet coil are working Okay, but there us still no output at the electrode tip, and the power supply to handle wire is Okay, then replace the resonator coil.REPAIR PARTS.

Packing, with Insert080-1500-1 Handle Assembly (Resonator), with 6 ft. CordSpecial Note Regarding CE Marking. The Model BD-50EV generates a high voltage corona of approximately 500 kHz. However by the very nature of its design, it will produce electromagnetic interference (EMI) as a result of its operation. Electric arc welders, for example, are another product that by its very nature and mode of operation produces EMI.As a result, the Model BD-50EV cannot meet the European Union Electromagnetic Compatibility (EMC) Directive 89/336/EEC, and cannot be CE marked.It does, however, meet EN61010-1:1993 Safety Requirements for Electrical Equipment for Measurement, Control and Laboratory Use, following the provisions of the Low Voltage Directive 73/23/EEC, as amended by 93/68/EECBecause of the risk of EMI, a risk assessment should be carried out prior to use of this equipment.The power output of the Model BD-50EV is limited. The effective range of EMI is less than about 1 meter on so in all directions. Metal objects nearby may bend or deflect this radiation. Therefore, there is some risk that it might interfere with electronic equipment 1 meter or so from this apparatus. This might include telephones, computers, cell phones, for example. Operators who wear pacemakers may also wish to consult with a physician prior to using this equipment.If interference with equipment is detected, move the Model BD-50EV further away, or schedule its operation when the affected equipment is not in operation. Consult plant safety personnel regarding its use.If you should have any further questions, contact Electro-Technic Products, Inc. for additional technical assistance.。
