Record the sales order number and/or serial number for future reference when ordering parts.Before Proceeding to Installation, Complete the Following:• Inspect all components for damage. Report any damage to the carrier within 24 hours of receiving.• Record the model and serial numbers for future reference when ordering parts.Model NumberSerial Number1.2 BEFORE YOU BEGINCAUTION! DURING THE INSTALLATION OF THE SINGLE-POINT, VERTICALLY-MOUNTED LIQUID LEVEL SWITCH, THE FLOAT AREA MUST BE KEPT FREE OF METALLIC PARTICLES THAT MIGHT BE ATTRACTED TO THE FLOAT’S INTERNAL MAGNET.1.2.1 Site PreparationEnsure that the length and the inside diameter of the mounting is sized correctly to accommodate the L-Series Single-Point, Vertically-Mounted Liquid Level Float Switch.1.2.2 Equipment and ToolsNo special equipment or tools are required to install the L-Series Single-Point, Vertically-Mounted Liquid Level Float Switch.The Following Are Recommended:• Wrenches, thread sealant, gaskets and/or bolting as required for the process connection.4L-SERIES SINGLE-POINT, VERTICALLY-MOUNTED LIQUID LEVEL FLOAT SWITCH5L-SERIES SINGLE-POINT, VERTICALLY-MOUNTED LIQUID LEVEL FLOAT SWITCH1.3 MOUNTINGThe L-Series Single-Point, Vertically-Mounted Liquid Level Float Switch is available in a variety of threaded mountings. These devices can be installed from the bottom or top of the tank. The switches should be mounted in an area clear of turbulence or direct streams.1.3.1 Threaded MountingHow to Install an L-Series Single-Point, Vertically-Mounted Liquid Level Switch:1 Apply either Teflon ® tape or an appropriate thread sealant to the mounting threads to prevent galling.2 Engage the thread by hand to avoid unnecessary damage.3 Using a wrench, rotate the unit clockwise until it is tight within the mounting.1.4 WIRINGCAUTION! OBSERVE ALL APPLICABLE ELECTRICAL CODES AND PROPER WIRING PROCEDURES.Contact Protection:In order to maintain the life and reliability of the internal reed switch, it is essential to provide protection when switching inductive loads. When the current breaks, the energy stored in the load generates a high frequency voltage across the switch contacts. If the voltage is large enough, it can initiate arcing and cause the contacts to weld together. Damage can ultimately be prevented by suppressing the voltage. Through the use of a diode for DC circuits and a resistor-capacitor network for AC circuits, contact protection willensure reliable performance from the reed switch.TOP MOUNT BOTTOM MOUNTANGLED MOUNT6L-SERIES SINGLE-POINT, VERTICALLY-MOUNTED LIQUID LEVEL FLOAT SWITCH2.0 PREVENTATIVE MAINTENANCEPeriodic inspections are necessary to maintain the proper functionality of the L-Series Single-Point, Vertically-Mounted Liquid Level Switch. The switch is a safety device that protects the equipment it serves. A systematic program of preventative maintenance should be implemented at the time of installation. If the following instructions are completed routinely, the switch will provide continuous, reliable protection.2.1 MAINTENANCE PROCEDURES 2.1.1 Inspect Unit PeriodicallyVerify that there are no cracks or chipped surfaces on the float or stem. Should the unit become damaged, obtain a replacement immediately.2.1.2 Inspect Connections MonthlyL-Series Single-Point, Vertically-Mounted Liquid Level Switches may be vulnerable to excessive heat and moisture. Under these conditions, the electrical wire insulation can periodically break or peel away. As a result, the bare wires may become exposed to the elements and cause damages.• Inspect all wiring, carefully and replace any wires exhibiting signs of brittle insulation.• Inspect all electrical connections to ensure tightness.• Repair or replace any wiring, if necessary.2.1.3 Keep Unit CleanPeriodic cleanings of the float, stem and magnet assembly will ensure the continual, uninterrupted movement of the mechanism. Always keep the open area between the enclosures clean and free of any potential interferences. Objects and debris may cause systematic interruptions and a loss in equipment functionality.2.2 WHAT TO AVOIDNEVER LEAVE THE SWITCH WIRING EXPOSED TO THE ELEMENTS.NEVER PLACE A JUMPER WIRE ACROSS THE TERMINALS TO “CUT-OUT” THE CONTROL. If a jumper is necessaryfor testing purposes, ensure that it is removed prior to placing the control into service.NEVER USE IN SYSTEMS CONTAINING IRON PARTICLES. The magnet within the float assembly can attract the particlesand become jammed.3.0 REFERENCE INFORMATIONThis section illustrates an overview of the L-Series Single-Point, Vertically-Mounted Liquid Level Switch, as well as information on troubleshooting common problems, agency approval listings, and detailed physical, functional and performance specifications.3.1 DESCRIPTIONThe L-Series Single-Point, Vertically-Mounted Liquid Level Switchis a float-actuated device designed to be vertically mounted within atank or process vessel through threaded connections. The low-costswitch is ideal for OEM applications where a single-point high or lowlevel alarm is desired.3.2 THEORY OF OPERATIONThe switching action is achieved through the use of an internalmagnet within the float assembly and its interaction with the switchmechanism. As the liquid level fluctuates inside the tank, the floatfollows.

However, if the liquid viscosity is low, then pointing downwards if often fine. Additionally, if the application is a high level alarm and its activation results in the machine shutdown for example, pointing downwards may be acceptable.If you wish to mount in this position, contact SST Sensing to discuss the implications.Avoid mounting positions where ambient light is likely to point directly at the sensing tip, as false readings can occur.Switch performance can be affected by reflective surfaces in front of the sensing tip. ContactSST Sensing if you wish to use a switch within 10mm of a reflective surface (see NOTE).NOTE:If you are installing an LLG switch, avoid reflective surfaces within 50mm of the sensing tip.Figure 3-1 - Example Mounting Positions3.2Electrical ConnectionsCAUTION:•Do NOT immerse the wires in fluid, over time, this will result in irreparable damage to the switch.•Take care when connecting loads. The minimum load impedance should not exceed Vs/max output current. Check the relevant datasheet BEFORE installation.•Shorting the output to Vs or 0V will result in irreparable damage to the switch.•Do NOT install the switch suspended from the cable.•Avoid exerting excessive tensile force on the cable (e.g. tugging).The liquid level switch termination configuration varies depending on the range and selection ordered (refer to the specific datasheet for more detail); in general, connect as follows:Optomax Digital, Industrial and Glass Tip Ranges∙Vs Red∙Output b Green∙0V BlueLLHP Range c∙Vs Red∙Output b Green or white∙0V Blue or blackPOS Range c∙Vs Brown∙Output b Black∙0V BlueOptomax Basic Range∙3-wire versiono LED Anode Redo Output b Greeno0V Blue ∙4-wire versiono LED Anode Redo Output b Greeno0V LED Blueo0V Phototransistor Blackb Refer to the datasheet for output logic details.c Brad Harrison connector available as an alternative to the cable / flying lead options.4OPERATIONOptical liquid level switches do not measure the liquid level, instead they detect the presence or absence of liquid. For an overview of the switches refer to AN-0061, Liquid Level Switches – Selection Guide, more detailed spec information is contained in the switch datasheets; refer to REFERENCE DOCUMENTS for details.4.1Operating Principle OverviewOptical liquid level switches use an infra-red LED and phototransistor accurately positioned at the base of the sensor tip.When the tip is in air, infra-red light reflects internally round the tip to the phototransistor providing strong optical coupling between the two. When the sensor tip is immersed in liquid, the infra-red light escapes from the tip causing a reduction in the amount of light at the phototransistor which makes the output change state.Sensor Tip in Air Sensor Tip Immersed in Liquid4.2Fluid Compatibility GuideThe environment in which the liquid level switch is operating influences the life of the product. To ensure the switch does not fail prematurely, the following material/fluid compatibility should be noted:4.2.1PolysulfoneWhilst the following list may be used as a guide and gives common industrial fluids that are typically acceptable, we recommend that before use you check that the fluid you wish to use this device in is compatible with Polysulfone.

We recommend that before use you check that the fluid you wish to use this device in is compatible with glass. Refer to 4.3 Test Process on page 4-4.4.3Test ProcessThe chemical compatibility lists are not exhaustive and customers often want to use the switches with liquids that have not been approved before. In this case, a compatibility test should be performed using a sensor made with the material (Polysulfone, Trogamid®, glass or stainless steel) you wish to use.The test is simple and is performed as follows:1.Submerge the sensor tip and threads in the liquid of interest. Do NOT submerge the wires.2.Heat the liquid to the maximum expected operating temperature.CAUTION: Assuming it is safe to do so.3.Leave the switch in this liquid at the maximum operating temperature for two weeks.4.Remove the switch and inspect it for signs of:∙Cracking∙Crumbling∙Crazing∙Melting∙Deformation∙SwellingAssuming the switch appears to be unaffected, it should be tested in accordance with its operating procedure to ensure it remains functional.If the switch passes its functional tests, then the liquid can be considered to be compatible with the switch housing material.5MAINTENANCE5.1CleaningIf cleaning of the tip is necessary (i.e., if there is a buildup of algae or other reside), clean the outer surfaces using alcohol based cleaning agents.CAUTION: If your switch is Polysulfone or Trogamid®, do NOT use chlorinated solvents such as tricholoroethane as these are likely to attack the switch material.5.2DisposalLiquid level switches contain electrical components, for this reason they must be disposed of as electrical waste. Please observe your local regulations.Page | 5-1AN-0041 Rev 8 © 2017 SST SENSING LTD.REFERENCE DOCUMENTSRefer also to the following documents for additional information:CAUTIONDo not exceed maximum ratings and ensure sensor(s) are operated in accordance with their requirements.Carefully follow all wiring instructions. Incorrect wiring can cause permanent damage to the device. SST Sensing Ltd recommend using alcohol based cleaning agents. If your switch is Polysulfone or Trogamid®, do NOT use chlorinated solvents such as trichloroethane as these are likely to attack the switch material.Failure to comply with these instructions may result in product damage.INFORMATIONAs customer applications are outside of SST Sensing Ltd.’s control, the information provided is given without legal responsibility.

液位检测系统安装及维护说明结晶器液位检测系统安装及维护说明一．安装注意事项：1．仪表安装必需牢固、可靠、通风好，便于检查、操作、维护。

2．中间接线盒安装在干燥、易检查、环境较好的地方。

3．仪表至接线盒的屏蔽电缆必需单独穿钢管敷设，屏蔽层必须接地。

4．探测器安装要紧固，最好做溢钢防护。

5．由接线盒至探测器的双头铠装电缆要穿钢管敷设，管口至探测器的裸露电缆部分最好用石棉布包好。

电缆两端的快速接头连接必需紧固、可靠、无松动。

如现场蒸汽较大，接头必需做防水处理。

6．安装放射源时，将铯源放置结晶器内时要快速，不易在手上停留时间过长。

如需从结晶器内取出铯源，要将铯源放置专用铅罐内。

二．标定：在更换探测器、铯源棒、结晶器后，确认结晶器通水，必须进行高、低液位标定。

低液位标定方法：先将钢块放入结晶器内，钢块上表面距铜管上口-200 mm处，再按操作箱面板上的“最小液位校验”按钮3秒，指示灯亮后松手，待灯灭后即完成。

高液位标定方法：将钢块放入结晶器内，钢块上表面距铜管上口-50mm处，再按操作箱面板上的“最高液位校验”按钮3秒，指示灯亮后松手。

待灯灭后即完成。

此工作建议在开机前做。

三．维护注意事项：1．定期检查仪表接线端子是否有松动。

2．中间接线盒定期打开检查是否受潮。

3．探测器要轻拿、轻放，避免碰撞损坏。

4．检修时要对电缆接头进行检查，看是否受潮、进水。

铠装电缆接头未跟探测器相连时，务必要包好接头，防止接头进水、损坏。

5．探测器在使用一年后，密封胶有可能老化，建议打开探测器检查后，对原密封处重新密封。

6．出现液位信号或者拉速信号不正常时，首先用万用表测量仪表接受和发出的信号是否正常，其次检查信号电缆是否正常，再次确认PLC或者变频器和液位显示表端的信号是否正常，最后排查信号干扰的可能性。
