Description
GLS and GLS-SS Series safety rope switches aredesigned to be mounted on machines and sectionsof conveyors which cannot be protected by guards. Incontrast to traditional mushroom head type emergencystop buttons, GLS and GLS-SS Series safety ropeswitches can initiate the emergency command fromany point along the installed rope length and providerobust emergency stop rope pull protection for exposedconveyors or machines. In combination with a dualchannel safety monitoring relay, GLS and GLS-SSSeries safety rope systems can be used as emergencystop devices monitored for up to PLe to ISO13849-1.All GLS and GLS-SS Series safety rope emergencystop switches conform to ISO13850 and EN60947-5-5.They have a positive mechanical linkage between theswitch contacts and the wire rope. The switches havewire-breakage monitoring. On pulling the rope the safetycontacts are positively opened and the auxiliary contactsare closed. The switches are mechanically latched andcan then only be returned to the operational condition bypressing the blue reset button as required by ISO13850.GLS Series are general/standard duty robust die-castsafety rope pull switch designed to protect conveyorlengths where protection is required up to 80 m (262.5')using two switches or up to 60 m (197') using a singleswitch. They provide a reliable general purpose safetysolution for conveyors and offer a choice of fittingsdepending upon the application. They can be suppliedwith a mushroom type emergency stop button whichcan be fitted to the side of the switch to offer an extratraditional emergency stop function close to the switch,or can be fitted later after installation without any extrawiring. A bi-color LED is also available to show switchstatus from a distance. Rugged internal sealing bellowsmeans the GLS Series can be high pressure hosed andthey are suitable for internal or external use.
The GLS-SS Series are general/standard duty stainlesssteel safety rope pull switches designed to protectlong conveyor lengths up to 100 m (328'). The 316 SShousings are designed specifically to withstand the harshenvironments found in the food and pharmaceuticalindustries. The fixing holes are under the cover ofthe switch to prevent food trap areas and will survivechemical and detergent washdown by providing allstainless steel parts and robust IP67 and IP69K sealingby using integral bellows and gaskets. An easily visiblebi-color LED is available to show switch status from adistance. Shorter rope spans up to 80 m (262.5') can beachieved by using just one switch therefore making acost effective solution and reducing electrical wiring runs.
