Risk assessment based 13849-1 9705
control component requirements specified risk assessment, possible risk parameters must selected based 13849-1: [severity injury (S), frequency and/or exposure time hazard (F), possibility avoiding hazard (P)]. When understanding these parameters `S', `P', when evaluating risk using these parameters, necessary know that parameters combined with each other, thus causing risk assigned control (safety) category. higher level risk, higher will risk components comprising selected safety measure. Risk assessment chart
Severity injury Slight injury [normally reversible (e.g. bruising and/or lacerations without complications)] Serious injury including death [normally irreversible (e.g. amputation death)] estimating risk arising from fault(s) safety-related parts control system, severity injury must first evaluated. injury slight injuries, select damage serious injuries including death, then select Frequency and/or exposure time hazard Seldom quite often and/or exposure time short Frequent continuous and/or exposure time long period exposure hazard should evaluated basis average value which seen relation total period time which equipment used. example, necessary reach regularly between tools machine during cyclic operation order feed move workpieces, then should selected. access only required from time time, then selected. Possibility avoiding hazard Possible under specific conditions Scarcely possible When hazard arises important know recognized whether avoided before leads accident. example, important consideration whether hazard directly identified physical characteristics, whether only recognized technical means, e.g. indicators. Other important aspects which influence selection parameter follows: operation with without supervision operation experts non-professionals speed with which hazard arises, e.g. quickly slowly possibilities hazard avoidance, e.g. taking flight intervention third party practical safety experiences relating process When hazardous situation occurs should only selected there realistic chance avoiding accident significantly reducing effect should selected there almost chance avoiding hazard.

High-performance sensors meeting needs workplaces around world
SF2-A series sensors utilize latest advances SUNX sensor technology provide variety useful functions while meeting international standards. They combine level safety required such standards with truly remarkable ease use. newly-developed light curtain, with radically features, contributes greatly improved safety workplace.
Convenient tool facilitates easy beam axis alignment Reduces installation time significantly
When upper half beam axes aligned
Unaligned beam axes seen glance
beam-axis alignment indicators distributed sensors four sections. indicators sections whose beams aligned light red, allowing user easily verify which beam axes have become aligned. Once beams have become aligned, indicators light green. Upon beginning alignment, soon bottommost topmost beam axis (the standard beam axis) becomes aligned, then corresponding bottommost topmost alignment indicator light will begin blinking red. Therefore, beam axes easily aligned performing initial beam axis alignment either bottommost topmost beam axis, then rotating light curtain around axis this beam. beam-axis alignment indicators provided both emitter receiver, that glance which beams aligned.
Beam axes correctly aligned Only bottommost beam axis correctly aligned
Conventional unit
After beam channels received light, number indicators that light will increase accordance with incident light level
SF2-A
Upper indicators light Lower indicators light
Even though some beam channels aligned, user cannot determine which beam channels aligned (Cannot determine which beam axes aligned)
Even though beam channels only partially aligned, user determine which beam channels aligned (Beam axes upper blocks aligned beam axes lower blocks aligned)
beam channels correctly aligned
Only beam axes lower blocks correctly aligned (Beam axes upper blocks correctly aligned)
First, ensure that bottommost beam axis correctly aligned
Rotate receiver around bottommost beam axis
Blinking indicators light bottommost indicator blinking bottom indicators light indicators light green
Mounting bracket enables easy beam-axis alignment
beam-axis alignment easy since angle adjustment possible with enclosed rear mounting bracket (MS-SF2N-1). Furthermore, optional side mounting bracket (MS-SF2N-3) also used side mounting.
Alignment beam axes accurately performed prior power-up
SF-LAT-2N Laser alignment tool utilized, then beam axes alignment quickly easily performed, using easy-to-see laser beam spot, even when light curtain units installed long distances apart. addition, SF-LAT-2N Laser alignment tool battery-operated; beam axes alignment performed before actual power-up light curtain itself.

Incorporates advanced ELCA function that prevents mutual interference reduces interference from extraneous light
Recognizes extraneous light prevents malfunctions
This function allows sensor recognize reject instantaneous interferences extraneous light emitted from peripheral equipment, thus preventing malfunctions caused variety sources, including: other sensor beams vicinity operating sensor, beam spatter, rotating light sources. reducing number malfunctions caused extraneous light, detection operations will interrupted less frequently, resulting tremendous improvements work efficiency.
Mutual interference reduced without need interference prevention lines
ELCA (Extraneous Light Check Avoid) function enhances functioning mutual interference prevention function. ELCA decreases interference from extraneous light having similar frequency light used SF2-A series, thereby also minimizing mutual interference among nearby SF2-A series sensors.
Reducing mutual interference High immunity interference from extraneous light

Thorough sensor protection measures have also been implemented
Spatter protection sensing surface
spatter protection hood type, available, protects sensing surface from welding machine spatter. Moreover, front protection cover that installed within sensor casing also available, completely preventing spatter from adhering sensing surface. addition, even though sensed objects contact sensor, sensing surface will protected. well, ELCA function implements possible measures prevent malfunctions caused spatter.
