Muting controller PLSG K

Safety Integrity Level SIL 3 (IEC 61508)
Performance Level PL e (ISO 13849-1)
Safety category cat. 4 (EN 954-1)

Funtional description

 that there is no space for entering the area between material and safety light barrier, or if there is no hazardous movement. Application fields are e.g. safeguarding of pallettizers, narrow-aisle storage facilities, fork lift access areas, manufacturing cells, bending presses, rubber presses, presses with automatic material feeders, etc ...

Muting(Bridging) with Muting time monitoring+++If material is conveyed through the protective field, or if, due to manufacturing conditions, in a certain sector of the work cycle any stopping during interruption of the protective field must be excluded.
Delayed end of Muting-++Manipulation safe Muting if conveyed material flow exits the dangerous zone towards the outside.
Immediate end of Muting when protective field is cleared again-++State of Muting remains only as long as it is basically required

BLVT-Light grid barriers. Fading out functions 11 kinds of protection field fading ou--+during first or rarely changed fading out the protection field fading out in the light grid barrier takes place via unique programming with the Hex-schwitches after a tension RESET. The fading out function remains stored in the light grid barrier up to a new programming
