Profitable connection in waterfall of switches and sensors of hygiene

With the presentation of the exclusive design of integration decentralised of Flexi Loop, Sick answers to the demand of connections in economic waterfall of switches and sensors of hygiene in a machine, as well as of abundant options of diagnostic, all this without leaving to keep a level of hygiene PL:and.

Like part of a solution of control Flexi Soft, Flexi Loop allows to integrate and diagnose individually until eight waterfalls of sensors, with a maximum of 32 switches of hygiene of dual channel and sensors of hygiene of affordable way. This does it especially interesting, from the technical and economic point of view, for machines and plants of production with a big number of doors, switches of with protection, resguardos and pulsadores of unemployment of emergency, in addition to resguardos protected by devices electrosensibles in the machines. His connection in waterfall by means of Flexi Loop results excepcionalmente economic due to the fact that all the ‘loop' only requires an entrance of conmutación safe and can use standard cables no apantallados of 5 threads with a connector M12.

Exist nodes of available connection for switches of electromechanical hygiene, as well as for sensors of hygiene with elements of conmutación of exit OSSD (Output Signal Switching Device) for the connection in series and the integration in the different modules of enlargement of the controller of hygiene Flexi Soft. The node Flexi Loop contains the signal of safe disconnection of all the waterfall, as well as the data of diagnostic of each integrated element in Loop. Besides, the sensors connected receive feeding of 24 V through Flexi Loop.

Exists a standard entrance (no safe) for each node, together with a standard exit (no safe) that admits switches of functions, blockades of doors or a light indicadora. The distance between nodes can be of until 30 m, what supposes that a ‘loop' in complete configuration can arrive to the 960 m of length. The data of diagnostic transmitted by each switch or sensor contain the information of disconnection (‘Who has accionado the conmutación?'), as well as, in case of failure, the cause of the error (‘Why took place the conmutación?'). This facilitates the diagnostic of the machine. The final result is that the fetter-jos of repair and maintenance can carry out fast and effectively, shortening the period of inactivity of the machine and the costs that this comports.

One of the big innovations of Flexi Loop is to do connections in waterfall safer. When they use conventional connections, is not possible to determine some errors, since these are ‘masked' by the connection in series. Flexi Loop Avoids this monitoring each one of the sensors. From the point of view of the technology of hygiene, the conventional connection of several sensors gives place to a descent of the level of hygiene until PL d or PL c; by the contrary, the connection in waterfall of switches and sensors with Flexi Loop fulfils the requirements of PL and according to DIN IN ISO 13849-1 at all times, whenever they use the suitable devices.

Flexi Loop Is compatible with switches and sensors of hygiene of any mark, preserving like this the independence of the manufacturer of the machine to the hour to realizar his shopping, in addition to the one of the final customer. The simplest, nevertheless, is to use the switches Sick with technology plug&play: thanks to his connectors M12 and to an allocation of pines suitable, come already prepared to work with Flexi Loop.
