SF SERIES SAFETY LIGHT CURTAIN INSTALLATION AND USAGE MANUAL Please read this document carefully and thoroughly before installation and operation, because the correct and optimum use of this product is important for the personal safety. Please give the user this document with the safety light curtain if you are an agent, a dealer or a machine manufacturer which forms a complete set, because this document is important to guide the user correctly to install and operate.

Foreword Thanks for choosing LNTECH safety light curtain, this operating instruction manual is designed to address the technical personnel of the machine manufacturer or the machine operator in regards to safe mounting, wiring, commissioning, operation and maintenance of the safety light curtain. The safety light curtain (herein after called "light curtain") is electro-sensitive protective equipment (ESPE); it is also named " opto-electronic sensor". It is mainly used in antomotive manufacturing,packaging and other automation fields, prevent staff entering the danger zone and being injured....

1.7 Terminology Emitter The emitter consists of emitter units; it can emit the modulated light signal. Sensor The sensor consists of emitter units and (or) receiver units. It can emit and (or) accept the modulated light and form light curtain with a reflector (or through reflector/mirror). Output a light passing signal or light intercepting signal to controller. In order to be advantageous for the description, sometimes also refers to the emitter and (or) the receiver. Reflector The reflector used to reflect the modulated light from emitter units to receiver units. Mirror The mirror used to...

1.8 Safety Instruction Safety light curtain is only taken as a kind of protection measure, can't completely rely on this for security! For example,when switch off the power to machines or danger area, the light curtain can't prevent the workpieces being ejected, dropped, radiated, also can't detect the transparant objects. According to the site situation sometimes need take other mechanical protection measures apart from safety light curtain Please follow the below procedures to ensure of proper and safety application. The GB/ISO regulations and directives are applicable to the...

2 Basic Introduction 2.1 External Dimension H：protection height L: sensor's height Unit: mm Fig.2-1 SF series sensor's dimension No blind zone design: SF series safety light curtain protection height is almost the same as the sensor's height, can extremely extend the protection area Slim and compact profile: metal housing with black end covers, elegant apprearance Protection height: the height depends on the constructure height, please see form 2.1. Protection width: width of the area protected by the size of the light path between the sender and receiver, and shall not exceed the maximum...
