Alarm Output Connection Section 3 - Operation3-1Main BoardThe Main Board is shown in Fig. 3-1. Here are the important components on the board:(1) - Terminal Block for Power & Output connections(2) - Single Turn Potentiometer to adjust Emissivity in tenths (0.x_)(3) - Single Turn Potentiometer to adjust Emissivity in hundreds (0._x)(4) -Slide switch to select between real time (Normal Operation) and alarm set point(5) - Alarm set point adjust, P4(6) - Sensor Head connection(7) - Input Zero adjust, P3(8) - Input Span adjust, P2(9) - Output Zero adjust, P5(10) - Output Span adjust, P6Figure 3-1. Main PC Board3.2Ambient TemperatureThe Sensing head can operate in an ambient temperature of 0 to 70°C (32to 158°F). The Sensing head in the high temperature model (-HT) can operate in an ambient temperature of 0 to 85°C (32 to 185°F) without any cooling required. The Sensing head can operate up to 200°C (392°F) using the water cool jacket accessory OS100-WC (See Fig. 3-6).There is a warm up period of 3 minutes after power up. After the warm up period, temperature measurement can be made.When the ambient temperature around the sensor head changes abruptly,the sensor head goes through thermal shock. It takes a certain amount of time for the sensor head to stabilize to the new ambient temperature. For example, it takes about 30 minutes for the sensor head to stabilize going from 25°C to 50°C (77 to 122°F) ambient temperature.The sensor head dimensions are shown in Fig. 3-2.Figure 3-2. Sensor Housing3-23-33.3Atmospheric QualityEnvironments with smoke, dust, and fumes dirty up the optical lens, and cause erroneous temperature readings. To keep the surface of the optical lens clean, the air purge collar accessory is recommended, OS100-AP , See Fig. 3-7.3.4Measuring TemperatureBefore starting to measure temperature, make sure that the following check list is met:ߜ The power and analog output connections are made (Fig. 2-1).ߜThe sensor head is connected to the main unit.ߜThe slide switch (SW1) on the main board is set to real time (Fig. 3-1).ߜThe target is larger than the optical field of view of the sensor head (Fig. 3-3).ߜThe emissivity adjustment on the main board is set properly (Fig. 3-1).ߜThe output load is within the product specification.On OS102 transmitters, follow these additional steps:ߜ The temperature display is set to °F or °C (Fig. 3-4)ߜ For 4-20mA output models, make sure an output load is added, ie. 250ohms.Figure 3-3.

SEC-MALS分子量检测
SEC-MALS分子量检测SEC-MALS（Size Exclusion Chromatography - Multi-Angle Light Scattering）是一种联用尺寸排阻色谱（SEC）和多角度激光散射（MALS）以精确测量分子质量和分子大小的绝对测定技术。
SEC根据不同分子量大小的蛋白通过多孔载体时所用的时间不同实现样品分离，而MALS技术则通过测量每个分子在不同角度下的散射光强度，计算获得分子的质量和大小。
SEC-MALS分析能提供关于分子质量、尺寸、形状和组装状态的准确信息，是深入理解生物大分子的结构和功能的重要工具。
SEC-MALS分子量检测基本原理。
SEC-MALS无需依赖柱校正和标样即可直接测定溶液中的大分子和纳米粒子的分子量和尺寸，被广泛应用于蛋白质、聚糖、聚合物、纳米粒子等的结构和动力学研究，以及生物药物的聚合和变性研究中广泛应用。
百泰派克生物科技BTP基于高效液相色谱仪建立了分子量测定平台，并通过CNAS/ISO9001双重质量体系认证，我们可以为您提供直接的SEC-MALS分子量检测服务，并提供包括方法学建立、验证和转让的完整服务。
实验仪器高效液相色谱（紫外检测器）：Waters 2695/2996。
技术应用可以对混合样品的分子量进行检测，适用于较为复杂的混合样品。
案例示意将准备好的样品加入SEC系统中，大的分子因为无法进入孔隙而先被洗脱出柱，小的分子则因为进入孔隙内部而后被洗脱出柱。
从SEC柱中洗脱的样品接着流入MALS检测器。
MALS检测器通过向样品散射激光并从多个角度测量散射光的强度，可以计算出样品的绝对分子量。
最后通过数据分析软件对MALS原始数据进行分析以获取样品的分子量和聚合度信息。

The devices being in some typical configurations during the test, it is impossible to guarantee results in all possible configurations.To ensure optimum operation of each device ,it would be judicious to comply with several recommendations of use.2) Recommendations:2.1) General information:- Comply with the mounting recommendations (mounting direction, devices spacing ...) specified in the datasheet.- Follow the recommendations of use (temperature range, protection) specified in the datasheet.- Avoid dust and excessive moisture, corrosive gases, sources of heat.- Avoid disturbed environments and disruptive phenomena.- If possible, group together the instrumentation devices in a zone separated from the power and relay circuits.- Avoid close proximity with remote switches for high power, contactors, relays, SCR ,...- Do not approach within two feet of a device with a walkie-talkie ( 5 W output power),because it creates a electromagnetic field with an intensity greater than 10 V / M for a distance of less than 50 cm.2.2 ) Power supply:- Observe the characteristics specified in the datasheet (Voltage and frequency tolerance).- It is preferable that the power comes from a system with section switches equipped with fuses forinstrumentation components, and the supply line is the most direct route possible from the section switch.Avoid using this power supply to control relays, contactors, solenoid valves, …- If the power circuit is heavily disturbed by SCR switching , motor, inverter, ...it may be necessary to install an isolation transformer specifically for instrumentationand connecting the screen to ground.- It is also important that the installation has a good grounding, and preferable that the voltagecompared to neutral does not exceed 1V, and the ground resistance less than 6 ohms.- If the installation is located near high frequency generators or arc welding, itis preferable to mount adequate power line filter.2.3) Inputs / Outputs:- In harsh conditions, it is advisable to use sheathed twisted cables whose ground braid will be grounded at on point.- It is advisable to separate the input/output lines from the power supply lines in order to avoid the coupling phenomena. - It is also advisable to minimize the lengths of data cables.E 8LOREME 12, rue des Potiers d'Etain - 57071 Metz ☎03.87.76.32.51-Fax03.87.76.32.52-Email:******************************@Loreme.frSOMMAIRE4-20 mA Current loop isolator and signal splitterSIL3 / SIL2, HART transparencyCertification to a Safety Integrity LevelThe International Electrotechnical Commission's (IEC) standard IEC 61508, defines SIL using requirements grouped into two broad categories: hardware safety integrity and systematic safety integrity.A device or system must meet the requirements for both categories to achieve a given SIL.The SIL requirements for hardware safety integrity are based on a probabilistic analysis of the device. To achieve a given SIL, the device must meet targets for the maximum probability of dangerous failure and a minimum Safe Failure Fraction. The concept of'dangerous failure' must be rigorously defined for the system in question, normally in the form of requirement constraints whose integ-rity is verified throughout system development. The actual targets required vary depending on the likelihood of a demand, the com-plexity of the device(s), and types of redundancy used.PFD (Probability of Failure on Demand) and RRF (Risk Reduction Factor) of low demand operation for different SILs as defined in IEC EN 61508 are as follows:For continuous operation, these change to the following.Hazards of a control system must be identified then analyzed through risk analysis. Mitigation of these risks continues until their over-all contribution to the hazard are considered acceptable. The tolerable level of these risks is specified as a safety requirement in the form of a target 'probability of a dangerous failure' in a given period of time, stated as a discrete SIL level.Abbreviation DescriptionHFT Hardware Fault Tolerance, capability of a functional unit to continue the execution of the demanded function when faults or anomalies exist.MTBF Mean interval between two failuresMTTR Mean interval between the occurrence of the failure in a device or system and its repairPFD Likelihood of dangerous safety function failures occurring on demandPFDavg Average likelihood of dangerous safety function failures occurring on demandSIL Safety Integrity Level, the international standard IEC 61508 defines four discrete safety integrity levels (SIL1 to SIL4).Each level corresponds to a specific probability range with respect to the failure of a safety function.The higher the integrity level of the safety-related system,the lower the likelihood of the demanded safety functions not occurring.SFF Safe Failure Fraction, the proportion of failures without the potential to put the safety-related system intoa dangerous or impermissible functional state.TProof In accordance with IEC 61508-4, chapter 3.5.8,TProof is defined as the periodic testing to expose errors in a safety-related system.XooY Classification and description of the safety-related system with respect to redundancyand the selection procedure used. "Y" indicates how often the safety function is carried out (redundancy)."X" determines how many channels must work properly.λsd und λsu λsd Safe detected + λsu Safe undetected Safe failure (IEC 61508-4, chapter 3.6.8):A safe failure is present when the measuring system switches to the defined safe stateor the fault signaling mode without the process demanding it.λdd +λdu λdd Dangerous detected + λdu Dangerous undetected Unsafe failure (IEC 61508-4, chapter 3.6.7):Generally a dangerous failure occurs if the measuring systemswitches into a dangerous or functionally inoperable condition.λdu λdu Dangerous undetected A dangerous undetected failure occurs if the measuring system does not switch into a safeE 9。

MOUNTING INSTRUCTIONS2The DRA-DCC-8 is designed for standard DIN rail mounting.Place the unit on the upper part of the mounting rail with the fastening tab facing down. Using a suitable flat screwdriver loosen the tab slightly and attach the unitto the rail. Once the tab is loosened, ensure that the unit is fastened securely in place.2. REPLACING FUSESIn order to replace a blown fuse, the unit has to be disassembled, as follows:a. Take off both terminal strips by removing the four screws at the edges. Note: This does not require disconnecting the cables connected to the strips.Remove the front panel using a suitable flat screwdriver. Press down gently on the plastic springloaded tabs located in the slots either side of the unit.c. Disconnect the flat connector which couples the LED circuit on the front panel.d. Replace the blown fuse.WARNING: Never install a fuse rated more than 800mA3. ASSEMBLYThe DRA-DCC-8 unit includestwo printed circuit cardsdesignated as P.N 7041 andP.N 7040. The two printedcircuit cards should occupythe slots in the enclosureaccording to fig 1.Figure 1Insert the two printed cards into their slots. Connect the flat cable between them. Connect the front panel flat cable. The panel must be inserted into the grooves on both sides of the case while pressing down until a distinct "click" is heard. Assembly is completed by laying the terminal strips in place.Note: The terminal strips are polarized and must not be placed backwards.b.4Figure 2.SW5 MSB Self Test Mode* according to para #5.26. PARALLEL CONTROL MODE* according to para #5.2In the parallel control mode, the DRA-DCC-8 unit is controlled via a 15 bit bus.Three Address bits (A0-A3) select the proper current output channel and 12 Data bits (D0-D11) determine its value (A0 and D0 are MSB). The DRA-DCC-8microprocessor continuously scans the input vector (Address + Data) terminals and updates its memory tables upon recognizing a new vector. The unit isasynchronous in nature. The data should be valid for at least 160 microseconds.S1S2S3S4S5S6S7SELF TEST#1ON OFF X OFFX OFF ON OFFX MODE ON ON OFFX SELF TEST#2SELF TEST#3**S1S2S3S4S5S6S7PARALLEL MODE OFF OFF *OFFX MODE 6.1 PLC INTERFACEThe PLC's output modules can be divided intothree popular types; TTL output module, 24Vdcsink type and 24Vdc source type.There is a jumper selector on printed circuit cardPN 7040 which selects between Sink/Sourceinput.

When E="0" the unit ignores any new input vector. The E terminal is recommended to be used as a strobe for parallel data which has a long setup time. In this case the following sequence is recommended: prior to applying a new vector, the E terminal should be set to logical 0 (inhibit state), then the new input vector should be imposed. Once the new data is set, the E terminal should be pulsed.The E terminal is also used for multidrop configuration. The 15 bit vectors are applied to the units in parallel and the selection is carried out by controlling the "E" inputs.7. SERIAL CONTROL MODEFigure 3.7.1 RS232c / RS422 SELECThe DRA-DCC-8 is equipped with two serialcommunication ports: The RS232c and theRS422. A jumper switch at the right side of theDIP switch array is used to select the requiredcommunication type. See figure 3.7.2 RS422 TERMINATION The SW8's ON state terminates the RS422 receiver terminals with a 100W load.In a multidrop configuration, the last (most distant) DRA-DCC-8 unit should be terminated in order to match the transmission lines.Note: Only one termination load per RS422 communication link is permissible.7.3 SERIAL CONTROL SWITCH SETTINGSS1S2S3S4S5S6S7BAUD RATE ID CODE *ON* according to para #5.27.4 SERIAL COMMUNICATION PARAMETERSThe communication protocol is 8 bit ASCII, even parity, and one stop bit.RS-422RS-232c7Note: If the value is omitted it will be treated as zero. Separators such as blanks or commas are not allowed.Example:Channel 4 in DRA-DCC-8 no. 7 has to receive the value of 981. Echo back is required The command format is:[C] [7] [4] [981] [CR]The echo back will be: C 7 4Note: The channel numbers on the DRA-DCC-8 front panel are designated from 1 to 8, in binary they are designated from 0 to 7.Note: When applying the echo back mode, it is advisable to wait for the echo back before transmitting a new command.7.4.3.3 STATUS REPORT FORMAT[S] [ID CODE] [CR]The addressed DRA-DCC-8 unit will respond with the values stored in its eight channels. The response will start with S, ID code, following with eight channel values separated with commas and [LF] [CR] as terminators.Example:DRA-DCC-8 unit number 3 has the following stored data: ch1: 300, ch2: 1270,ch3: 0, ch4: 4087, ch5: 2099, ch6: 764, ch7: 3078, ch8: 550. The response from the device will be:S3,300,1270,0,4087,2099,764,3078,550 [LF] [CR].Note: Wait until the status report has terminated before transmitting new commands.8. SELF TEST MODESThe DRA-DCC-8 is provided with three test modes.S1S2S3S4S5S6S7SELF TEST#1ON OFF X OFFX OFF ON OFFX MODE ON ON OFFX SELF TEST#2SELF TEST#3*** according to para #5.2[C] [ID CODE CHANNEL] [LF] [CR]88.1 SELF TEST #1 (Communication Ports Test)In order to test the serial communication ports, this test mode converts the unit to a transponder for ASCII characters. Any transmitted character will be echoed to the host terminal. The host parameters should be set to:Baud rate : 4800, Word length: 8 bits, Parity: even, Stop bit: 18.2 SELF TEST #2 (Same Leve)lIn this test mode, the DRA-DCC-8 unit ignores the address field. All the outputs are set according to the data field only.8.3 SELF TEST #3 (Saw Tooth)In this test mode, only one output channel (according to the address setting) will produce a saw tooth wave form in which the whole value range is used.9. MULTIDROP CONFIGURATIONUp to eight DRA-DCC-8 units can be installed in a multidrop configuration using the RS422 communication port.The controller's RS-422 transmitter is connected to the units' receivers while the controller's RS-422 receiver is connected to the units' transmitters.As the communication cable might be several thousand feet long, it is necessary to terminate the end of the line with its characteristic impedance in order to avoid reflections in the transmission line causing data distortion. SW8 in its ON state terminates the Rx inputs with a 100Ωload.10. PUTTING THE UNIT INTO OPERATIONThe DRA-DCC-8 is supplied with a set configuration for parallel control mode.The DIP switch setting is:The communication port selector (see para #7.1) is set to RS232C.The unit should be set up according to the required configuration.Before applying voltage to the unit see para #4 for power supply consideration.S1S2S3S4S5S6S7PARALLEL 4-20mA ON OFF OFF OFF OFF OFF OFF MODE911. DRA-DCC-8 CALIBRATIONGenerally there is no need to calibrate the DRA-DCC-8 unit. However if calibration is required, the following steps should be carried out: Two potentiometer trimmers,one for "Zero" and the other for "Span" are located on printed card 7040. The trimmer close to the card edge is the "Zero". Use the following switch setup for switching all the outputs between 4 and 20mAStep 1:Select one channel (for example ch.#1) for the initial tuning. Set the DIPswitch array to "all 4mA".Apply supply voltage to the unit. The initial state of all the output currents is 4 e SW2 to switch all the outputs between 4 and 20mA. Iteratively set the "Zero"and the "Span" trimmers for 4.00mA and 20.00mA.Step 2:Monitor all the 8 channels in 4mA state, and calibrate the Zero trimmer so that their average readings is 4.000mA.Then repeat for 20mA state, and calibrate the Span trimmer so that their average readings is 20.000mA. This procedure should be repeated until calibration is satisfactory.In the parallel control mode, internal pull-up resistors on each of the input terminals keep them in logical 1 state. The unit will recognize input voltage up to 0.5V as logical 0 and voltages from 4V to 60V as logical 1.Note: After every power on, the unit is reset and the initialized default output currents are according to the SW6 setting (see para #5.2).Note: Set the unit to sink mode (fig.2).S1S2S3S4S5S6S7ALL CH. = 4mA ON OFF OFFOFF X ALL CH. = 20mA ON OFF ON OFFX X X X X MODE The channel LEDs are connected in series with the output current so that they will light only as an indication of a closed current loop.INPUTS:PARALLEL INPUTSLOGIC LEVELS:DATA HOLD TIME:MAXIMUM PARALLEL INPUT RATE: SERIAL COMMUNICATION BAUD RATES:PARITY:STOP BIT:STATUS REPORT:MULTIDROP CAPABILITY: OUTPUTS:OUTPUT CURRENT SPAN: OUTPUT CURRENT SETTLING TIME: POWER SUPPLY:CURRENT CONSUMPTION: MAXIMUM LOOP RESISTANCE: ACCURACY: RESOLUTION: INDICATORS:AMBIENT TEMPERATURE Operation:Storage:RELATIVE HUMIDITY:HOUSINGBox:Terminals:MOUNTING:FUSE:WEIGHT:DIMENSIONS:Parallel & Serial control inputs3 - Output current loop address12 - Output current value (Data)1- Enable (E)0<"0"<0.5V, 4 <"1"< 60V160 microsecond6000 updates per secondRS232c full duplexRS422 full duplex300, 4800, 9600, 19200 BPSEvenOneReports as interrogatedUp to eight units8 continues current loops0-20mA or 4-20mA (user selected)4.2 ms max. for 99% of step15-32 Vdc (regulated)85mA max.According to Rmax(KΩ)= (Vsupply -6)/20±0.1% of span typical, ±0.2% of span max.0.025% of span typical,0.05% of span max.
