LTC1290中文资料

LTC1290中文资料特点：1、软件可编程-单极性/双极性转换-四差分/八单通道输入-MSB/LSB前导数据序列-可变输出数据字长-电源关闭2、内置采样保持器3、5V或者±5V供电4、对大多数处理器可以四线串行接口也可以和所有的微处理器并行端口5、50kHz的最大吞吐率主要技术指标:-12位的分辨率-快速转换的时间:最大13us-低供应电流: 6.0mA描述：LTC1290是一种数据采集的器件，包含一个串行I / O逐次逼近式A/ D转换器。

它使用LTCMOS开关电容技术进行12位单极性和11位加号双极性转换。

8通道输入，8个通道可以配置成8个单通道也可以是差分输入。

对所有的单端输入有一个片内采样保持器。

需要低功耗时，可以通过串行口进行编程，将LTC1290掉电休眠。

串行I / O被设计成符合工业标准的全双工串行接口。

输出数据字可以被编程为8、12和16位输出。

这易于界面转移数据和多种多样的处理器。

管脚定义CH0-CH7：模拟输入通道，所有输入必须相对于AGND没有噪声。

COM：单通道输入时，用来定义零基准，与地相接，必须没有噪声。

DGND：数字地，片子内部逻辑的参考地。

AGND：模拟地，与电路中的模拟地相连。

V：负电压输入端。

REF-和REF+：基准电压输入端，REF-接地,REF+接正电压。

CS：片选端，低电平时选中片子。

OUT D ：串行输出转换结果。

IN D ：数字地址输入端，CS 置低电平后，AD 配置地址从此输入。

SCLK ：移位时钟，用来同步AD 串行数据传送。

ACLK ：AD 转换时钟，用来控制AD 转换过程。

CC V ：正电源，必须避免干扰，信号应该绕开地线。

典型连接电路：极限值：正供电电压：CC V 到GND 或者V -…………12V 负供电电压(V -)：-6V~GND电压：模拟/参考电压输入：(V -)-0.3V~ CC V +0.3V 数字输入：-0.3V~12V数字输出：-0.3V~ CC V +0.3V功耗：500mw工作温度范围：LTC1290BC, LTC1290CC, LTC1290DC ....0℃to 70℃LTC1290BI, LTC1290CI, LTC1290DI ....–40℃ to 85℃ LTC1290BM, LTC1290CM,LTC1290DM...........................–55℃ to 125℃储存温度： –65℃to 150℃ 焊接温度： 300℃（10S ）转换器和通道特性注：标志表示所有测量数据是在整个温度操作范围内进行的，没有这个标志的是在典型的25℃下进行的。

SilverStone Strider Essential 500W 电源说明书

SPECIFICATIONSilverStone Strider EssentialST50F-ES230ATX12V Switching Power SupplyWith Active PFCPS/2011.1 ScopeThis specification defines the performance characteristics of a single phase 500 watts, 5 output power supply. This specification also defines worldwide safety andelectromagnetic compatibility requirements for the power supply which is intended for use in computer products.1.General2.1 Input VoltageNominal Voltage Voltage Variation Range 230 Vrms 207 - 253 Vrms 2.Input Characteristics2.2 Input FrequencyNominal Frequency Frequency Variation Range 50 Hz 47 Hz to 63 Hz* The power supply must operate at above frequency with 207 - 253VACrms input voltage range.02Maximum continuous total DC output power should not exceed 500W.Maximum continuous combined load on +3.3VDC and +5VDC outputs shall not exceed 120W.NOTE:Noise test should be measured with 20 MHz bandwidth frequency oscilloscope.The output terminal shall add a tantalum capacitor of 10uF in parallel with a ceramic capacitor of 0.1uF.2.3 Max. Input AC CurrentMax. Input Current Measuring Range 4.0A 207-253 Vrms2.4 Inrush CurrentThe power supply must meet inrush requirements for any rated AC voltage, during turn on at any phase of AC voltage, during a single cycle AC dropout condition, during repetitive ON/OFF cycling of AC, and over the specified temperature range. The peak inrush current shall be less than the ratings of its critical components (including input fuse, bulk rectifiers, and surge limiting device).2.5 EfficiencySST-ST50F-ES230 provides an efficiency of >80% when measured at full load under 230V/50Hz condition.3.1 Normal Operation Output3.Output characteristics033.2 Remote On/Off Controlled modeThe PSON# signal is required to remotely turn on/off the power supply, PSON# is an active low signal that turns on the output power rails. When this is not pulled low by the system, or left open, the outputs (except the +5VSB) turn off. This signal is pulled to a standby voltage by a pull-up resistor internal to the power supply. TTL level "H" 2.0 V - 5.25 V "L" 0.0 V – 1.0 V3.3 RegulationThe cross regulation defined as follows, the output regulation should be within the specified range.3.4 Rise TimeDC output rise time is less than 20 mS at nominal line and full load.3.5 Hold-up TimeDC +5V output maintains at least 8mS after power off which hold within para 3.1 under 230V/50Hz condition.3.6 5VSB5VSB is requierd for the implementation of PS-ON described above. 5VSB is a standby voltage that may be used to power circuits that require power input during the powered-down state of all power rails. The 5 VSB pin should deliver 5V ± 5% at a minimum of 2.5 A for PC board circuits to operate. Conversely, PC board should draw no more than 2.5A maximum form this pin. This power may be used to operate circuits such as soft power control.043.7 PG-OKPG-OK is a power good signal and should be asserted high by power supply to indicate that the +5 VDC and +3.3 VDC outputs are above the under-voltagethresholds of the power supply. When this signal is asserted high, there should be sufficient mains energy stored by the converter to guarantee continuous power operation within specification. Conversely, when either the +5VDC or the +3.3VDC output voltage falls below the under-voltage threshold, or when mains power has been removed for a time sufficiently long so that power supply operation is no longer guaranteed, PG-OK should be deasserted to a low state. See Figure 1 for a representation of the timing characteristics of the PG-OK,PS-ON, and germanepower rail signals.3.8 3.3V SenseA default 3.3V sense line should be implemented pin 13 of the connector.3.9 Capacitive LoadThe power supply should be able to power up and operate normally with the following capacitances simultaneously present on the DC outputs.4.1 Input ProtectionIn primary circuit of the power supply , a protected fuse is inserted. Only internal fault of the power supply will cause the fuse blown. Any overload or short circuit at DC output will keep from fuse brown or fire hazard.4.Protection4.2 Output Protection4.2.1 Under voltage protection 4.2.1 Under voltage protectionThe +5V/+3.3V DC output are protected against the under voltage condition . range value can't be exceed 3.3~3.7V at 5V terminal and 2.0~2.4V at 3.3V.054.2.2 Over Voltage ProtectionThe +5V/+12V/+3.3V DC output are protected against the over voltage condition . Maximum value can't be over 6.5V at 5V terminal and 15.5V at 12V, 4.3V at 3.3V. 4.2.3 Over Power ProtectionThe power supply can be used electronic circuit to limit the output current against exceeding 60% of surge output power or protected against excessive power delivery since short circuit of any output or over total power at high line.4.2.4 Short Circuit ProtectionShort circuit placed on +5V,+12V,+3.3V,-12V will latch off. +5VSB will auto-recovery.5.1 No Load StartWhen power is applied to SST-ST50F-ES230 with no load connected or under minimum load connected, neither damage to power supply nor hazards to users will occur.5.Start Stability5.2 Cold StartThe power supply shall operate properly when first applied at normal input voltage and or so maximum load after 4 hours storage in 0℃ environment.6.1 Temperature and Humidity6.2 AltitudeThe power supply can operate normally at any altitude between 0 to 10000 feet.6.Environments6.1.1 Operating Temperature 0 to 40 ℃ Relative Humidity 20 to 90 %6.1.2 StorageTemperature -40 to 70 ℃Relative Humidity 20 to 95 % noncondensing6.3 Vibration and ShockSweep and resonance search for each of X,Y,Z, axis at the sweep.RATE of 1/OCTAVE/Min.06FCC,CE7.

Main transformer shall similarly withstand 3000Vacapplied between both primary and secondary windings for a minimum of one minute.A TTL compatible signal for the purpose of initiating an orderly start-up procedure under normal input operating conditions. During power up, this signal is asserted ( low ) until +5V is under regulation and AC reaches min. line specification range. After all voltage are going appropriate level, the system may have a turn on delay of 100mS, but no greater than 500mS. During power off the signal should go to low level before +5V is out of regulation. The low level is 0 to 0.8V and high level is 4.75 to 5.25V. The " Power Good "signal can drive up to 6 standard TTL loads.9. Power Good Signal07The MTBF of the power should be 50,000 hours min10.

Long operating times and critical atmospheres place heavy demands on any lighting system, and maintenance is often associated with major effort and high costs.The Tridonic range of products are perfect replacements for fluorescent and HID light sources as they meet all the requirements for industrial lighting.Reliable light for every needHeavy industryBecause of its complex production process, the heavy industry is characterised by extreme environmental conditions. Multiple cooling and heating steps in the production process lead to major differences in temperature within the production hall. Theluminaires are continuously exposed to vibrations, shocks, enormous forces and a high level of dirt. The luminaires are continuously exposed to vibrations, shocks, enormous forces and a high level of dirt. A high degree of reliability reliability is essential to enable continuous operation.According to the HACCP guidelines, the prescribed minimum temperature for deep-freeze warehouses and deep-freeze logistics centres is below-18 °C. Depending on the products the temperatures are therefore between -18 °C and -30 °C. In order to avoid devices malfunctioningat these extreme temperatures, cold-resistant equipment and electronicssuitable for deep-freezing must be used and precise placement ensured.LED Driver from Tridonic for industrialapplications have been designed to reducestress on the components and lead to longlife (thermal load/peak voltage).

Both 3-lead packages are RoHS compliant.Glossary of TermsMilliTesla (mT), Gauss Units of magnetic flux density: 1mT = 10 GaussHazardous SubstancesRoHS RestrictionofSOT Small Outline Transistor (SOT package) - also referred with the package code “SO”DischargeESD Electro-StaticDirect-CurrentBLDC Brush-LessOperating Point (B OP) Magnetic flux density applied on the branded side of the package which turns the outputdriver ON (V OUT = V DSon)Release Point (B RP) Magnetic flux density applied on the branded side of the package which turns the outputdriver OFF (V OUT = high)Unique FeaturesBased on mixed signal CMOS technology, SS569 is a Hall-effect device with high magnetic sensitivity. This multi-purpose latch meets most of the application requirements.The chopper-stabilized amplifier uses switched capacitor technique to suppress the offset generally observed with Hall sensors and amplifiers. The CMOS technology makes this advanced technique possible and contributes to smaller chip size and lower current consumption than bipolar technology. The small chip size is also an important factor to minimize the effect of physical stress. This combination results in more stable magnetic characteristics and enables faster and more precise design.The wide operating voltage from 2.5V to 24V, low current consumption and large choice of operating temperature range according to “L”, and “E” specification make this device suitable for automotive, industrial and consumer applications.Pin Definitions and DescriptionsSOT Pin №SIP Pin №Name Type Function1 1 VDD Supply Supply Voltage pin2 3 OUT Output Open Drain Output pinpinGround3 2 GNDGroundTable 1: Pin definitions and descriptionsAbsolute Maximum RatingsParameter Symbol Value UnitsSupply Voltage V DD 28 VSupply Current I DD 50 mAOutput Voltage V OUT 28 VOutput Current I OUT 50 mA150 °CStorage Temperature Range T S -50toMaximum Junction Temperature T J 165 °CTable 2: Absolute maximum ratingsOperating Temperature Range Symbol Value Units85 °CTemperature Suffix “E” T A -40to150 °CTemperature Suffix “L” T A -40toExceeding the absolute maximum ratings may cause permanent damage.

Therefore, it requires both south and north poles to operate properly.The OUT pin of these devices switches low (turns on) when a magnetic field perpendicular to the Hall sensor exceeds the operate point threshold, B OP . After turn-on, the output voltage is V DSon . Note that the device latches, that is, a south pole of sufficient strength towards the branded surface of the device turns the device on. The device remains on if the south pole is removed (B →0). This latching property defines the device as a magnetic memory.When the magnetic field is reduced below the release point, B RP , the OUT pin turns off (goes high). The difference in the magnetic operating and release points is the hysteresis, B HYST , of the device. This built-in hysteresis prevents output oscillation near the switching point, and allows clean switching of the output even in the presence of external mechanical vibration and electrical noise.The device behaves as a latch with symmetric operating and release switching points (B OP =|B RP |). This means magnetic fields with equivalent strength and opposite direction drive the output high and low.Powering-on the device in the hysteresis region (less than B OP and higher than B RP ) allows an indeterminate output state. The correct state is attained after the first excursion beyond B OP or B RP .The SOT-23 device is reversed from the UA package. The SOT-23 output transistor will be latched on in the presence of a sufficiently strong North pole magnetic field applied to the marked face.Flux density18Gs typOUT = LowOUT = LowUA package - Latch characteristicOP 18Gs typ-18Gs typ-18Gs typFlux densitySO package - Latch characteristicApplication InformationIt is strongly recommended that an external bypass capacitor be connected (in close proximity to the Hall sensor) between the supply (VDD Pin) and ground (GND Pin) of the device to reduce both external noise and noise generated by the chopper stabilization technique. As is shown in the two figures in next page, a 0.1μF capacitor is typical. For reverse voltage protection, it is recommended to connect a resistor or a diode in series with the VDD pin. When using a resistor, three points are important:- the resistor has to limit the reverse current to 50mA maximum (V CC / R1 ≤ 50mA)- the resulting device supply voltage V DD has to be higher than V DD min (V DD = V CC – R1*I DD ) - the resistor has to withstand the power dissipated in reverse voltage condition (P D = V CC 2/R1) When using a diode, a reverse current cannot flow and the voltage drop is almost constant (≈0.7V).Therefore, a 100Ω/0.25W resistor for 5V application and a diode for higher supply voltage are recommended. Both solutions provide the required reverse voltage protection.When a weak power supply is used or when the device is intended to be used in noisy environment, it is recommended that the figure 13.3 from the Application Information section is used.The low-pass filter formed by R1 and C1 and the Zener diode Z1 bypass the disturbances or voltage spikes occurring on the device supply voltage V DD . The diode D1 provides additional reverse voltage protection.The SS569 have been optimized for commutation applications in 5V and 12V brushless DC motors. The follow figure is the typical application circuit for 3 phase brushless DC motors.Automotive and Severe Environment Protection Circuit Typical Three-Wire Application CircuitStandard information regarding manufacturability of Hall IC with different soldering processesOur products are classified and qualified regarding soldering technology, solderability and moisture sensitivity level according to following test methods:Reflow Soldering SMD’s (Surface Mount Devices)J-STD-020• IPC/JEDECMoisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices(classification reflow profiles according to table 5-2)JESD22-A113• EIA/JEDECPreconditioning of Nonhermetic Surface Mount Devices Prior to Reliability Testing(reflow profiles according to table 2)Wave Soldering SMD’s (Surface Mount Devices) and THD’s (Through Hole Devices)• EN60749-20Resistance of plastic- encapsulated SMD’s to combined effect of moisture and soldering heat• EIA/JEDEC JESD22-B106 and EN60749-15Resistance to soldering temperature for through-hole mounted devicesIron Soldering THD’s (Through Hole Devices)• EN60749-15Resistance to soldering temperature for through-hole mounted devicesSolderability SMD’s (Surface Mount Devices) and THD’s (Through Hole Devices)• EIA/JEDEC JESD22-B102 and EN60749-21SolderabilityESD PrecautionsElectronic semiconductor products are sensitive to Electro Static Discharge (ESD).Always observe Electro Static Discharge control procedures whenever handling semiconductor products.Package UA, 3-Pin SIP:Package SO, 3-Pin SOT-23:SOT-23 Package Hall Location:Ordering InformationPart No. Pb-free Temperature Code Package Code PackingSS569ESOT YES -40°C to 85°C SOT-23 7-in. reel, 3000 pieces/reel SS569EUA YES -40°C to 85°C TO-92 Bulk, 1000 pieces/bag SS569KSOT YES -40°C to 125°C SOT-23 7-in. reel, 3000 pieces/reel SS569KUA YES -40°C to 125°C TO-92 Bulk, 1000 pieces/bag SS569LSOT YES -40°C to 150°C SOT-23 7-in. reel, 3000 pieces/reel SS569LUA YES -40°C to 150°C TO-92 Bulk, 1000 pieces/bag。

If you want to break this application limitation, it is required to use two-stage compressor or cascade system. Meanwhile, the working condition of high pressure ratio brings problems to the traditional single-stage compressors during compression process, such as excessive gas leakage and high exhaust temperature etc., which leads to low efficiency and poor reliability when it is working is such harsh conditions.The compound two-stage compressor well solves above problems. Compared with the two-stage compressors or cascade system, the compund two-stage compressors occupy less space and the system is easy to control, so it's more efficiency and reliable.LT Series compound two-stage compressor’s evaporation temperature can be as low as -60~-65°C , Its full load evaporating temperature can be -25°C, LT-S-L Series compound two-stage low temperature compressor is based on the LT-S series which modified the internal structure and optimized the motor matching to increase the compressor full-load evaporation temperature to -10 °C, So that LT-S-L series can meet the requirements of industrial refrigeration、quick freezing tunnel and freezing library without pre-coolingFor above reasons, Therefore The Shanghai Hanbell Precise Machinery Co., Ltd. developed the LT series high temperature compressors. High efficiency and reliability under big pressure differential and compression ratio working condition is the main demand in designing. It is a elitist product which accumulates Shanghai Hanbell's rich technology and extensive application experience. It can be widely used in many industries such as high temperature hot water, central heating and so on.2.

As shown in Figure 3-1 below.When the spool is fully in contact with the suction side, the screw rotor is in full-load suction state, at which time the working volume of the compressor is maximized. As the spool is separated from the suction side, it moves toward the exhaust side. A bypass cavity is formed between the slider and the suction side.Its presence causes the compressed gas in this range to be bypassed directly to the low pressure, and the actual suction volume of the screw rotor is reduced.The more the slide valve moves toward the exhaust side, the smaller the actual suction volume of the compressor will be.And the system cooling capacity will also reduce The slide valve is driven by the pressure differential among the internal capacity modulation system.The lubricant comes from the external oil separator and passes through the oil filter then enters into the oil inlet port of the compressor, and at last divided to bothsides of the piston. As a result, the piston can be controlled by discharging the high pressure lubricant at one side to low pressure, letting it flow to the low pressure side so that the slide valve will move with the piston to realize the loading and unloading of the compressor.The purpose of the piston spring is to push the piston to its initial position (min. load position), so as to realize the automatic unloading start. It not only reduces the mechanical impact on the compressor's moving parts, but also reduces the electrical current during compressor start up.Stepless capacity control, solenoid valve(SV1:unloading, SV3:50%, SV5:100%) is controlled by a micro controller or a thermal switch to adjust the piston smoothly to stably control cold output. If the oil filter capillary or solenoid valve of the capacity modulation system don't work properly, it will cause the capacity modulation system to be abnormal and fail.Figure 3-1.Capacity Modulation System3.2.1 Step type capacity modulation system1） Step type control logicY: Energize the solenoid valve N: Do not energize the solenoid valveTable 3-1. Step Type Capacity Modulation Control Logic2） Step type capacity modulation graphFigure 3-2. Step Type Capacity Modulation3）Step type control logic description10% loadFigure 3-3. 10% LoadWhen starting up thecompressor, SV1(unload) &SV2 (10%) need to beenergized to make the pistonkeep at the 10% position(leftside)In this state, the highpressure oil passes throughSV1(unload) then goes to theright side of the piston. At thesame time, the oil from left side of the piston passes through SV2 (10%) then discharge to the low pressure side. By doing so, the piston can be held at the 10% load position.★ Note: 10% load is for start up only. Running the compressor at 10% load for a long time is not recommended.50% loadAt this time, the capacity adjustment solenoid valves SV1 (unload) and SV3 (50%) are active.Under 50% load, SV1(unload) &SV3 (50%) are energized.In this state, the high pressure oil passes to the left side of the piston continuously. At the same time, the oil passes through SV1 (unload) then goes to the right side of the piston.If the piston is at the left side of the 50% hole (the loading is less than 50%), the oil at the right side of the piston will pass through SV3 (50%) and discharge to the low pressure side then the piston will move to right side until the position blocks the 50% hole. Thus the compressor is loaded to 50% smoothly.Vice versa, if the piston is at the right side of the 50% hole (the loading is more than 50%), the oil in the left side of the piston will pass through SV3 (50%) and go out to the low pressure side then the piston will move to left until the position blocks the 50% hole. Thus the compressor is loaded to 50% smoothly.75% LoadUnder 75% load, SV1（unload）&SV4 (75%)are energized.The logic of 75% load issimilar to that of 50%. Thepiston can be held around75% position by 75% holeto make the compressorrun under 75% load.Figure 3-5.75% Load100%LoadUnder 100% load, SV5(100%) is energized. In this state,the high pressure oil passes to theleft side of the piston continuously.At the same time, the oil in theright side of the piston passesthrough SV5 (100%) then goes tothe low pressure side to make thepiston be held at 100% position.fig3-6.100% Load4） Step type capacity modulation and water temperature controlFigure 3-7.Step type capacity modulation and water temperature control★Note: T & T' should be adjusted by system designer’s experience and practical application.Time启动Set point + 2TSet point + TSet pointSet point – T'Storage temperaturet1 t21~3min 60~90 sec3.2.2Stepless type capacity modulation systemStepless type is suitable when the refrigeration system needs to achieve precise control of cooling capacity.1）Stepless type control logicTable 3-2. Stepless Type Capacity Modulation Control Logic 50%~100%2）Stepless type capacity modulation graphFigure 3-8.Stepless Type Capacity Modulation3）Stepless type control logic descriptionIn stepless type capacity modulation system, the oil keeps going to the left side of the piston. The oil bypass in the left side of the piston is controlled by SV3 (50%). The oil inlet in the right side of the piston is controlled by SV1 (unload) and oil bypass in the right side of the piston is controlled by SV5 (100%). These three solenoid valves are controlled by temperature controller or PLC.Through the three solenoid valves, the cooling capacity can be controlled at any position from 50%~100%, so through periodical adjustment of SV1、SV3、SV5, the energy output can controlled stably.★Note: SV2(10%) can only be used for machine start and stop. Don't run the machine at 10% load for long time once the machine is started. It shall be switched to load model directly.The stepless type capacity modulation system shall be connected to the micro controller(optional), eg. PLC etc. in order to control the system at the target working condition.LoadDuring load process, the SV5 (100%) adopts pulse activating, and the rest solenoid valve are not energized.In this kind ofsituation, the highpressure oil goes into theleft side of the pistoncontinuously and the oilin the right side of thepiston bypasses throughSV5 (100%) to the lowpressure side.The piston willcontinue to move to theright side and thecompressor completeload process.Figure 3-9. LoadUnloadDuring unload process,the SV2(50%) stays active,and SV1 (unload) adopts pulseactivating, and the restsolenoid valve are notenergized.The high pressure oilcontinues to go to the left sideof the piston and goes into theright side of the piston passingthrough SV1(unload).Through SV3(50%), it Figure 3-10. Unload bypasses to the low pressure side, so that the piston continues to move to the left side, and the compressor will load to 50% piston.Keep load stateFigure 3-11. Keep Load StateDuring this process, all S/V are not energized. The high pressure oil coming continues to go to the left side of the piston. The left side oil inlet of the piston SV1(unload) and SV5(100%) are closed to keep the oil amount in the right side of the piston. The piston will not be able to move and stay at its original position, so that the compressor capacity will not change as well.Stepless type capacity modulation and water temperature controlBelow picture shows the load control of single compressor in the application of stepless type capacity modulation.Figure 3-12.

Hanbell designs for LT compressor the function of unloading startup. To ensure compressor loads steadily, please follow Figure 3-16 to load step by step during the whole loading process.When compressor is about to shut down, it is also required to unload to ensure that the slide valve is at lowest loading position during next startup and compressor could have an unloading startup. Thus Hanbell requires no matter what load condition of the compressor is, it should be unloaded step by step till minimum load before stop according to below Figure 3-16.Figure 3-16. Compressor Startup and Stop ProcessCaution：1）A fter startup, keep the minimum load for 10 seconds. Before shut down, keep the minimum load for 30 seconds(Time can be set to 10~60seconds).2）A fter startup, when the pressure difference between high pressure and middle pressure is less than 3.5bar, the compressor shall be run at 10% load at low pressure stage. Don't load and open ECO.3）t=30 seconds(Time can be set to 30~60seconds).4）A fter the compressor shut down, the SV1 (unload) & SV2(10%) need to be still energized for 3 minutes, so as to ensure the compressor can still at min load position at next startup.5）H anbell strongly recommends that the compressor start-up and shutdown control logic shall refer to above graph. For detail informationplease refer to the regulations written in LT-S Control Requirements.4.LubricantTable 4-1. Lubricant SpecificationCaution:1）P lease refer to the table above to select the suitable lubricant and refrigerant and its operation range need to be taken into consideration as well.2）H anbell strongly recommends do not use the lubricant which isn’t certified by Hanbell since it may damage the compressor seriously.3）T his specification table is for LT series compressors only.4）T he oil temperature at the point when the compressor starts is suggested to be 5K higher than the corresponding saturation temperature of the oil separator in order to avoid too much oil containing in the refrigerant which may affect the lubricant. 5）A fter compressor stops, please turn on the oil heater of the external oil separator.If the compressor shuts down for a long time, please turn off the oil heater. Please heat the lubricant for more than 2 hours before next start up.1）B e sure to make the system clean and no welding spatter and other impurities before lubricant filling2）I n order to ensure that the system is dry enough, it should be dehumidified before filling. It is advisable to fill the system with dry nitrogen first and then vacuum the system. The vacuum time should be as long as possible. It is strongly recommended to repeat the above steps several times to minimize the water contained in the system.Caution1）D o not use the lubricant which is not approved by Hanbell, otherwise it may causeserious damage to the compressor2）D o not mix different brands of lubricants, otherwise they may cause serious damage to the compressor. Pay attention to it when replacing lubricating oil for the system.4.2The Replacement of Lubricant4.3.1Oil Change Schedule1）C heck lubricant every 10,000 hours after continuous running. For the first operation of the compressor, it is recommended to change the oil and clean the external oil filter after running 2,000 hours. Check the system whether clean or not and then change oil every 20,000 hours or after 4 years continuous running if the system operates in good condition.2）T he oil will deteriorate if the compressor runs at high discharging temperature (above 95℃) in the long term. Please avoid this situation, but if it’s necessary to run in this condition, please shorten the intervals of oil changing.4.3.2Pre-cautions for changing oil1）I t is recommended to check the quality of oil periodically in order to maintain the lubrication performance.2）T he lubricant absorbs moisture in the air. Avoid to expose it to the air for a long timeIf the compressor motor is burned, the acid and harmful substances and burned debris will be brought into the system. Therefore, the oil filters and lubricants must be replaced repeatedly. It is suggested to replace the lubricating oil again after 72 hours of operation until the quality of the lubricating oil in the system returns to standard valve.3）T he foreign body in the oil will block the oil line, so it is necessary to install an oil filter in the external oil line. Also, the pressure differential sensor need to be installed before and after the oil filter. If the pressure differential valve between these two sensors reaches 1.5 bar, the oil filter need to be changed.4）T he acidity of oil will directly affect the life of the motor, and it is recommended to change the oil when PH≤6. (Please also change the filter drier at the same time to make sure the system is dry.）5）I t is important to replace the oil, especially when the motor is burnt because the acidity remains in the system. By replacing the oil can help check the status of thesystem. Check the acidity of the lubricant, and re-change the oil after the system runs for 72 hours until the acidity of the lubricant reaches the standard valve.6）I n case of motor burned out, please not only change the compressor, but also change the oil and check the condition of the oil periodically. If the acidity excesses the standard, please change it immediately and always be aware of the cleanliness and moisture contained in the system.5. System Application★Note ：Please consult Hanbell for parallel application and heat pump application.5.1 Piping Design5.1.1 Suction and Discharge Piping Layout1）Material and structure of suction and discharge pipeThe vibration of the compressor is small in normal operation, so it is not necessary to use flexible joints for suction and discharge tubes, but the pipes need to have enough flexible length to ensure the suction and discharge pipes won't cause any stress to the compressor. It is recommended to use copper tube for the suction and discharge piping in order to decrease the piping vibration when the compressor is in operation.2）The dimensions of suction and discharge piping:It is suggested to design the dimension of suction and discharge piping according to Hanbell recommendation (refer to 10.2.2).3）Piping for parallel systemTo improve the system operation efficiency, it’s necessary to reduce the gas -flow resistance and consider the oil return of suction piping. The recommended piping of suction and discharge side for parallel system is shown below:Be aware of the area of the main pipe should not be less than the area of the other pipes to make sure the pressure drops could be controlled in reasonable range. ❆ Piping at discharge side❆ x x xFigure 5-2 Suction Piping for Parallel SystemDetail Drawing 2 4) Suction filterThis model of compressor has a built-in suction filter, but it is only used as a final protection. It should not be used as an suction filter that needs to be cleaned regularly.So It is necessary to install a suction filter (25μm) which is easy to remove and clean it regularly.When the system is first used, it may need to be cleaned up frequently. If the pressure drop is bigger than 0.5 bar, the filter element should be replaced or cleaned until the system is clean. When the filter is disassembled, if the filter is found to be damaged, it needs to be replaced in time, and the impurities in the pipeline should be cleaned up. Ensure that the filter is oriented correctly during installation and it is recommended to add a shut-off valve at the inlet and outlet for easy maintenance.Hanbell The recommended suction filter design is shown in Figure 5-3 below.Figure 5-3.suction filterx xx Detail Drawing 2★Note：External suction filter should be used for cryogenic refrigeration systems。
