IF THE EQUIPMENT IS USED IN A MANNER NOT SPECIFIED BY THE MANUFACTURER, PROTECTION PROVIDED BY THE EQUIPMENT MAY BE IMPAIRED.1.1 UNPACKINGUnpack the instrument, carefully. Make sure that all components have been removed from the packing material. Inspect all components for damage. Report any concealed damage to the carrier within 24 hours of receiving. Compare the contents with the packing slip and report any discrepancies to the factory immediately. 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. Its magnetic field actuates the switch inside the stem andcloses an electrical circuit.FLOAT SWITCH DIAGRAM3.3 TROUBLESHOOTINGThe L-Series Single-Point, Vertically-Mounted Liquid Level Switch is designed and engineered for trouble-free operation over a wide range of operating conditions. Common problems are discussed in terms of their symptoms and recommended corrective actions.3.3.1 External CausesAn initial indication of improper operation is the failure of the controlled equipment to function (pumps will not start or stop, signal lamps fail to light, etc). If these symptoms occur, whether at the time of installation or during routine service thereafter, check for potential external causes first:• Blown Fuses• Tripped Reset Button(s)• Open Power Switch• Faulty Equipment Controlled By the Level Switch• Defective Wiring to the Level SwitchL-SERIES SINGLE-POINT, VERTICALLY-MOUNTED LIQUID LEVEL FLOAT SWITCH78L-SERIES SINGLE-POINT, VERTICALLY-MOUNTED LIQUID LEVEL FLOAT SWITCH3.3.2 Unit CausesIf a thorough inspection of any external causes fails to locate the problem, proceed to an inspection of the unit, itself.DISCONNECT POWER TO THE LEVEL SWITCH BEFORE PROCEEDING.If you are still in doubt about the condition or performance of your control, consult the factory for further instructions.3.4 AGENCY APPROVALS3.5 SPECIFICATIONS3.5.1 Physical Specifications3.5.2 Electrical SpecificationsL-SERIES SINGLE-POINT, VERTICALLY-MOUNTED LIQUID LEVEL FLOAT SWITCH910L-SERIES SINGLE-POINT, VERTICALLY-MOUNTED LIQUID LEVEL FLOAT SWITCH3.5.3 Dimensional Specifications3.6 NOTESHEX11L-SERIES SINGLE-POINT, VERTICALLY-MOUNTED LIQUID LEVEL FLOAT SWITCH3.7 MODEL CONFIGURATOR3.8 REPLACEMENT PARTSWhen Ordering, Please Specify:• Model & Serial Numbers• Name & Part Number of Replacement Part or AssemblyAll replacement parts are for standard models only.

安装时注意事项
安装位置与抽水机入水口应保持适当距离以免浮 球液位计被入水口吸入。
安装位置与入水口应保持适当距离以免被水冲击 造成感应不正确；若无法避免时可加装防波管或 防波板改善。
浮球液位开关工作原理
浮球液位开关工作原理
浮球液位开关是一种常用的液位测量仪器，其工作原理是通过浮球的上下浮动来检测液体的液位高低。
浮球液位开关包含一个密封的浮球和一个与其相连的开关组件。
具体而言，当液体的液位升高时，浮球会随之上浮，直到达到预定的高位位置。
在浮球上方的开关组件会受到浮球的上浮而受压，从而使开关闭合。
这时，浮球液位开关会输出一个信号，表示液位已经达到高位。
相反地，当液体的液位下降时，浮球会随之下沉，直到达到预定的低位位置。
在浮球下方的开关组件会受到浮球的下沉而释放，从而使开关打开。
这时，浮球液位开关会停止输出信号，表示液位已经低于设定的低位。
浮球液位开关常用于液体容器或储罐中，用于控制液位高低。
当液位达到设定的高位位置时，浮球液位开关会触发相应的控制系统，例如关闭进液阀门，以避免液体溢出。
当液位降至设定的低位位置时，浮球液位开关会触发相应的操作，例如打开排液阀门，以补充液位。
总的来说，浮球液位开关利用浮球上下浮动的原理，通过开关组件的闭合和断开来检测液体的液位高低，从而实现液位的控制和监测功能。
