Timing begins when the Emergency Source (generator) becomes available. TDNE：Adjustable from 0 to 99 seconds.3.3 TDEN SettingsTDEN provides a time delay when transferring from Emergency to Normal. This permits stabilization of the Normal Power before transferring back to normal. Timing begins when the Normal Power returns and becomes available and steady.TDEN：Adjustable from 0 to 99 seconds.3.4 TDEC SettingsTDEC timer keeps the generator running without load (E ngine C ool-down) after the ATS transfer back to Normal Power. Timing begins when the transfer back to normal is completed.TDEC：Engine Cool-down - from 0 to 99 sec.3.5 TDES SettingTDES is the time delay for Engine Start when the Normal Source voltage is in over or under-voltage (OV or UV). If power return to normal while timing, the TDES timer resets and starts again.TDES：Adjustable from 0 to 30 seconds.3.6 TD-OFF SettingTime Delay on OFF this timer keeps the switch in the center neutral OFF position (completely disengaged) before transferring to the other side. You can preset the switch in Neutral or OFF from 0 to 18 seconds (Normally 2 to 3 sec).TD-OFF：Adjustable from 1 to 20 seconds.3.7 Plant ExerciserThis feature provides for automatic test operation of the generator. The interval is fixed at once per 1 to 4 weeks with a specific test day and time. The exerciser can be set for either testing with load or without load. When the exerciser is activated the exerciser LED (EX) on the right side of display flashes and turns on during the exercise period.3.8 Over / Under Voltage SensingThe TC-V2 constantly monitors normal & emergency power. When power falls outside the programmed voltages this LED turns RED from GREEN and flashing to show OV / UV problems.Adjustable over voltage range：110 - 280 VacOver voltage reset：When voltage falls below 10 Vac of the OV setting.Adjustable under voltage range：80 - 230 VacUnder voltage reset：When voltage exceeds 10 Vac of the UV setting.3.9 Transfer FailureWhen a transfer is made the TS125 communicates it’s position to the TC-V2 controller by using two small internal micro-switches, if this signal is not received, it will try switching 3 more times every 2 seconds or until the connection is made. A flashing light indicator and a “FAIL” signa l displayed an incomplete transfer and that the ATS mechanism or wiring is defective.If the ATS fails, the TC-V2 controller stops all ATS functions and starts’ flashing until the failure is corrected and the control is reset.To reset the transfer fail alarm：1. Manually move the ATS to the correct position.2. Press any button (Auto, Program or Test) on thefront panel to reset the alarm.SECTION 4 : OPERATION4.1 GeneralThis section specifically describes the operation and functional use of the TC-V2 controller.4.2 AUTO ModeIn AUTO the TC-V2 controller automatically transfer and retransfers from source to source as directed by the pre-programmed instructions.In AUTO the controller monitors the condition of both normal and standby power sources providing the logic for the transfer operation.4.3 TEST ModeThe TC-V2 is equipped with a test pushbutton that simulates the loss of normal source. Pushing the Test key the TC-V2 will execute a test on the ATS. The TDES and TDNE programmed time delays will be performed as part of the test. There are two test modes：●Testing with load .●Testing without load4.4 Programming ModeThe TC-V2 controller is fully programmable from the front panel when in the Program Mode. The build-in program buttons have multiple functions：●Real time clock displaying●Programming mode operatingTo enter programming mode, push and hold Program button for 10 seconds. In the first 10 seconds the screen showing internal real time clock and then the word “ Vr 1.0” will appears on the front display window for 2 seconds indicating the version of the software.At this time start a line by line programming sequence. To advance to the next line, push the Program button on the front panel. To change each line’s programming parameters, press the increase (∧) and decrease (∨) buttons. When pressing and releasing the (∧) or (∨) key the displayed parameter can be increased or decreased by one. The parameter will continue to scroll if the (∧) or (∨) button is pressed and not released. Always push the “ Program” button to advance to the next line or until the word “ End” appears on the screen. To immediately end the programming mode, you simply push the “ Program” button for 4 seconds. Then the word “ End” shows on the screen indicating the end of the programming mode.If you like to return to factory settings, stay in programming mode and simultaneously press all 3 buttons (∧), (∨) and Program buttons for 4 seconds. The TC-V2 will now automatically program itself to factory settings and the word “ Au.Po” will appear on the display window.4.5 AC Voltage Display AdjustmentThe TC-V2 controller continually monitors normal & emergency power displaying volts and frequency on the front panel. (The voltage value is calibrated and adjusted at the factory). But when the ATS works on high capacitive or inductive loads the waveform distortion may cause the displayed to have slight differences from the users measuring instrument.You can adjust the display value to equal to the users own instruments, by entering the setting mode to perform adjustment the parameter. Once the adjustment is completed, the voltage sensing value will increase or decrease according to the adjusted value and display it on the screen. The TC-V2 over and under voltage protection follow the adjusted value as the actual system voltage and perform the monitoring according to the new parameter.See Table lines 2, 3, 4, 5 for voltage display setting. 4.6 Specification Summary4.7 System Setting Reference TableSECTION 5 : INSTALLATION INSTRUCTIONS5.1 GeneralThe TC-V2 controller is modular and is designed for installation next to switch or on the front door panel.

Application Note1.Air tight is needed between front cover of speaker and housing, otherwise cause audioperformance's losing, such as higher THD, lower sensitivity;2.Tiny air leakage in back of speaker is permitted to keep balance of air pressure;3.For this speaker, the standard power is 0.7W in 1cc back cavity, when the back cavity is less ormore than the standard volume of back cavity, the handling power also will be changed. See below figure about the relationship between power handling and back volume, here the power is excursion limited power; the thermal power should be evaluated, especially in small back cavity, such as 0.5cc. And the recommend minumum back volume is 0.5cc.4.If the power higher than 0.7W input the speaker in standard back cavity, there is the risk ofdamaging speaker. In case of the back volume larger than 1cc, i.e. 1.5cc, the power handing of the speaker is pretty low. To maintain the rated power as 0.7W, we suggest adding thicker mesh with more acoustic resistance on the cover to reduce the vibration amplitude, or using electric filter to attenuate the maximum vibration amplitude.(Figure 13)TEL:86-573-84645930 、84646197FAX:86-573-84646190TYPE NO.XHS151114SW47P42-01 Issue:A/2E-mail: services@.5.Resonance frequency VS sealed back volumeT he resonance frequency of the speaker box will vary with different sealed back volume.(Figure 14)6.

PIN二极管开关

PIN二极管开关微波开关利用PIN管在直流正、反偏压下呈现近似导通或断开的阻抗特性，实现了控制微波信号通道转换作用。

PIN二极管的直流伏安特性和PN结二极管是一样的，但是在微波频段却有根本的差别。

由于PIN二极管I层的总电荷主要由偏置电流产生，而不是由微波电流瞬时值产生的，所以其对微波信号只呈现一个线性电阻。

此阻值由直流偏置决定，正偏时阻值小，接近于短路，反偏时阻值大，接近于开路。

因此PIN二极管对微波信号不产生非线性整流作用，这是和一般二极管的根本区别，所以它很适合于做微波控制器件。

UC1875/6/7/8UC2875/6/7/8UC3875/6/7/8DESCRIPTIONThe UC1875family of integrated circuits implements control of a bridge power stage by phase-shifting the switching of one half-bridge with respect to the other,allowing constant frequency pulse-width modulation in combi-nation with resonant,zero-voltage switching for high efficiency performance at high frequencies.This family of circuits may be configured to provide control in either voltage or current mode operation,with a separate over-current shutdown for fast fault protection.A programmable time delay is provided to insert a dead-time at the turn-on of each output stage.This delay,providing time to allow the resonant switching action,is independently controllable for each output pair (A-B,C-D).With the oscillator capable of operation at frequencies in excess of 2MHz,overall switching frequencies to 1MHz are practical.In addition to the stan-dard free running mode,with the CLOCKSYNC pin,the user may configure these devices to accept an external clock synchronization signal,or may lock together up to 5units with the operational frequency determined by the fastest device.Protective features include an undervoltage lockout which maintains all out-puts in an active-low state until the supply reaches a 10.75V threshold.1.5V hysteresis is built in for reliable,boot-strapped chip supply.Over-current protection is provided,and will latch the outputs in the OFF state within 70nsec of a fault.The current-fault circuitry implements full-cycle restart operation.(continued)Phase Shift Resonant

synchronization pin):Used as an output,this pin provides a clock signal.As an input,this pin provides a synchronization point.In its simplest usage,multiple devices,each with their own local oscillator frequency,may be connected together by the CLOCKSYNC pin and will synchronize on the fastest oscillator.This pin may also be used to synchronize the device to an external clock,provided the external signal is of higher frequency than the local oscillator.A resistor load may be needed on this pin to minimize the clock pulse width.E/AOUT (error amplifier output):This is is the gain stage for overall feedback control.Error amplifier output volt-age levels below 1volt will force 0°phase shift.Since the error amplifier has a relatively low current drive capabil-ity,the output may be overridden by driving with a suffi-ciently low impedance source.CS+(current sense):The non-inverting input to the cur-rent-fault comparator whose reference is set internally to a fixed 2.5V (separate from VREF).When the voltage at this pin exceeds 2.5V the current-fault latch is set,the outputs are forced OFF and a SOFT-START cycle is initi-ated.If a constant voltage above 2.5V is applied to this pin the outputs are disabled from switching and held in a low state until the CS+pin is brought below 2.5V.The outputs may begin switching at 0degrees phase shift be-fore the SOFTSTART pin begins to rise --this condition will not prematurely deliver power to the load.FREQSET (oscillator frequency set pin):A resistor and a capacitor from FREQSET to GND will set the oscillator frequency.DELAYSET A-B,DELAYSET C-D (output delay control):The user programmed current flowing from these pins to GND set the turn-on delay for the corresponding outputpair.This delay is introduced between turn-off of oneswitch and turn-on of another in the same leg of thebridge to provide a dead time in which the resonantswitching of the external power switches takes place.Separate delays are provided for the two half-bridges to accommodate differences in the resonant capacitor charging currents.EA–(error amplifier inverting input):This is normally con-nected to the voltage divider resistors which sense thepower supply output voltage level.EA+(error amplifier non-inverting input):This is normally connected to a reference voltage used for comparison with the sensed power supply output voltage level at the EA+pin.GND (signal ground):A ll voltages are measured with re-spect to GND.The timing capacitor,on the FREQSET pin,any bypass capacitor on the VREF pin,bypass ca-pacitors on VIN and the ramp capacitor,on the RAMP pin,should be connected directly to the ground plane near the signal ground pin.OUTA-OUTD (outputs A-D):The outputs are 2A to-tem-pole drivers optimized for both MOSFET gates and level-shifting transformers.The outputs operate as pairs with a nominal 50%duty-cycle.The A-B pair is intended to drive one half-bridge in the external power stage and is syncronized with the clock waveform.The C-D pair will drive the other half-bridge with switching phase shifted with respect to the A-B outputs.PWRGND (power ground):V C should be bypassed with a ceramic capacitor from the VC pin to the section of the ground plane that is connected to PWRGND.Any re-quired bulk reservoir capacitor should parallel this one.Power ground and signal ground may be joined at a sin-gle point to optimize noise rejection and minimize DC drops.RAMP (voltage ramp):This pin is the input to the PWM comparator.Connect a capacitor from here to GND.A voltage ramp is developed at this pin with a slope:dV dT S ense Voltage R C S LOPE RAMP=•Current mode control may be achieved with a minimum amount of external circuitry,in which case this pin pro-vides slope compensation.Because of the 1.3V offset between the ramp input and the PWM comparator,the error amplifier output voltage can not exceed the effective ramp peak voltage and dutycycle clamping is easily achievable with appropriate val-ues of R SLOPE and C RAMP .SLOPE (set ramp slope/slope compensation):A resistorfrom this pin to VCC will set the current used to generatethe ramp.Connecting this resistor to the DC input linevoltage will provide voltage feed-forward.SOFTSTART (soft start):SOFTSTART will remain at GND as long as VIN is below the UVLO threshold.SOFTSTART will be pulled up to about 4.8V by an inter-nal 9µA current source when VIN becomes valid (assum-ing a non-fault condition).In the event of a current-fault (CS+voltage exceeding 2.5V),SOFTSTART will bepulled to GND and them ramp to 4.8V.If a fault occursduring the SOFTSTART cycle,the outputs will be imme-diately disabled and SOFTSTART must charge fully prior to resetting the fault latch.For paralleled controllers,the SOFTSTART pins may beparalled to a single capacitor,but the charge currents will be additive.PIN DESCRIPTIONSUC1875/6/7/8UC2875/6/7/8UC3875/6/7/8VC (output switch supply voltage):This pin supplies power to the output drivers and their associated bias cir-cuitry.Connect VC to a stable source above 3V for nor-mal operation,above 12V for best performance.This supply should be bypassed directly to the PWRGND pin with low ESR,low ESL capacitors.VIN (primary chip supply voltage):This pin supplies power to the logic and analog circuitry on the integrated circuit that is not directly associated with driving the out-put stages.Connect VIN to a stable source above 12V for normal operation.To ensure proper chip functionality,these devices will be inactive until VIN exceeds the up-per undervoltage lockout threshold.This pin should by bypassed directly to the GND pin with low ESR,low ESL capacitors.NOTE:When VIN exceeds the UVLO threshold the sup-ply current (I IN )will jump from about 100µA to a current in excess of 20µA.If the UC1875is not connected to a well bypassed supply,it may immediately enter UVLO again.VREF:This pin is an accurate 5V voltage reference.This output is capable of delivering about 60mA to peripheral circuitry and is internally short circuit current limited.VREF is disabled while VIN is low enough to force the chip into UVLO.The circuit is also in UVLO until VREF reaches approximately 4.75V.For best results bypass VREF with a 0.1µF,low ESR,low ESL,capacitor to the GND pin.PIN DESCRIPTIONS (cont.)APPLICATION INFORMATION Undervoltage Lockout

The temperature response is standard response (5mm glass bulb) and quick response (3mm glass bulb). The sprinklers come with compact design, glass bulb type, available in several different finishes and temperature ratings. The pendent sprinklers must be installed in pendent position, and upright sprinklers are to be installed in the upright position.Pendent Recessed Sprinklers are installed with adjustable or non-adjustable Escutcheon plates (also termed as Rosette plates). These are intended to be installed with finished ceilings. Escutcheon plate adjustment provides convenience in Pendent Sprinkler installation in case of areas with finished ceilings or walls.Sprinkler OperationThe Sprinkler operating device is state of the art heat responsive frangible glass bulb supplied by a world leader in this innovative technology. The glass bulb contains fluid which expands when exposed to heat. When rated temperature is reached, the bulb shatters and water flows through the sprinkler and strikes deflector, forming a uniform water spray pattern to control or extinguish fire.Care and HandlingSprinklers must be handled with due care, they must be stored at ambient temprature for best results. Storage as well as any onward shipment is to be made in original packing only. Sprinklers must be visually inspected carefully before installation. Sprinklers visibly damaged, dropped or exposed to temperature in excess of the maximum ambient temperature permitted, should never be installed. Never install any glass blub sprinkler if the bulb is cracked or if there is a loss of liquid from the bulb. Sprinkler must be installed after the piping is in place to prevent mechanical damage.Use T eflon Tape or soft thread sealent on male thread of the Sprinkler for the leak tight Sprinkler joint. A leak-tight 3/4” NPT or BSPT sprinkler joint should be obtained by applying a maximum torque of 27 N-m. Excessive tightening torque may distort the Sprinkler inlet and cause leakage. Sprinkler must never be painted, plated or coated after they leave factory.The HD Sprinkler described herein must be installed and maintained in accordance with the latest edition of HD technical data, the latest standard of National Fire protection Association (NFPA) and Factory Mutual (FM) or to the standard of any other authorities having jurisdiction. The owner is solely responsible for maintaining their fire protection system and device in proper operating condition.Inspection Testing and MaintenanceRefer to NFPA 25 for inspection testing and maintenance requirement or to the authority having jurisdiction. For details of warranty, refer HD’s current price list, conditions of sale or contact HD directly. Exposure to ultraviolet or direct sunlight for extended period may cause the liquid dye in glass bulb to fade or lose colour . Colourless or faded coloured bulbs are not a problem, as long as the fluid level has not been affected. The loss of colour in the liquid will not effect sprinkler performance, as long as the bulb is intact and not damaged. The loss of colour may be an issue in identifying sprinkler temperature rating, but the temperature rating is still stamped on the sprinkler deflector .SPRINKLER RATINGSAs per Table 6.2.5.1 NFPA 13DIMENSIONS (FRAME & DEFLECTOR FINISH)SL.NO PART NAME 1FRAME 2DEFLECTOR 3CAP 4CAP SEAT 5LOAD SCREW 6SEAL 7BULB 8SPRINGHD 172HD 272HD 171HD 271RECESSED PENDENTPENDENT & UPRIGHT SPRINKLERMAXIMUM EXTENSION MAXIMUM RECES SPENDENTUPRIGHTTolerance for all dimensions ± 0.5 mmDISTRIBUTION PATTERNSDistribute the water distance (cm)M o u n t i n g h e i g h t (c m )305245185135753052451851357550100150200250300120230K8.0 UPRIGHT SPRINKLERDISTRIBUTION PA TTERNS - TRAJECTORYDistribute the water distance (cm)M o u n t i n g h e i g h t (c m )305245185135753052451851357550100150200250300120230K8.0 PENDENT SPRINKLERDISTRIBUTION PA TTERNS - TRAJECTORYDISCHARGE CURVETOOLSSPRINKLER WRENCH SPRINKLER KEYLIMITED WARRANTYHD FIRE PROTECT PVT.
