In this applicationthe safety sensor monitors the closed position of hinged,sliding or removable guards with the aid of a coded actuator.The CSS 180 Safety Sensor fulfills the requirements for proximitydevices with defined behavior under fault conditionsaccording to EN 60947-5-3 with the classification PDF-M(self-monitoring).OperationThe CSS 180 Safety Sensor and CST 180 actuator are amatched pair. As the actuator approaches the sensor, thesensor excites the actuator at a predetermined resonantfrequency and the reads back the actuator oscillation. Thesensor evaluates the actuator frequency and its distance tothe actuator.Identification of the actuator is interpreted as a closed guardby the safety sensor, and the safety outputs are enabled.The safety sensor is a dual channel design with two shortcircuitproof, safe PNP outputs, each of which can switch upto 500 mA. Due to continuous internal function tests and themonitoring of the safety outputs, a number of CSS 180 SafetySensors can be wired in series without detriment to the controlcategory. Series wired safety sensors continue to fulfill therequirements of Control Category 4 according to EN 954-1.CSS-8-180-2P+D-E-LCSS-8-180-2P-Y-LCSS-8-180-2P+D-M-LCST-180-1CSA-M-1End or single device with diagnosticoutput, pre-wired cableSeries device with double pre-wired cableSeries device with diagnostic output,pre-wired cableActuatorMagnetic latchH-18 Mounting clampSensors available with M12 cable connector – Add ST after L incatalog numberSafety Control Module RequirementsDual-channel safety inputs, suitable for PNP semiconductoroutputs. The internal function tests of the sensor causethe outputs to periodically switch off for a millisecond.This must be tolerated by the control module. The followingSCHMERSAL safety control modules are recommendedfor this application: SRB 301 LCB and SRB 324ST*Note: A safety control module may be required for resetfunction and/or feedback monitoring functions, aswell as increased output current requirements.Typical ApplicationsThe sealed, compact units are ideal for use on movablemachine guards where multiple guard monitoring on amachine is required, and/or where hostile environmentsexist. Typical applications include printing machinery, textilemachinery, paper converting equipment, material handlingsystems, packaging machinery, chemical processing equipment,and woodworking machinery.154
