SLC Guard locking safety switch The new generation of safe mechanical guard locking switches

Surely. Exactly the right solution. With machines, it is imperative to ensure that there is no access or entry to the dangerous area after the process has been switched off. If, for example, we think of a large flywheel mass such as rotating saw blades, the machine operator shall have no access to the dangerous area until the dangerous movement has come to a complete standstill. Safety switches with guard locking such as the SLC ensure that safety guards, doors and other covers remain closed as long as a dangerous condition persists.

MANY FEATURES AT A GLANCE • • • • • • • • • • Lightweight yet robust: Hybrid of metal and plastic Flexible contact assembly I ntegrated manual release Symmetrical design Five actuating positions Rotatable head ( 4×90°) Fail-safe guard locking system Optional emergency release Optional escape release M12 connector as an option Thought through and cost-effective. Economical and user-friendly. The coded SLC has been re-thought and is a further development from BERNSTEIN with optimised functions in many respects. During development, it was important to reduce the functions to the essentials, to...

Actuator straight (ACS-1) Proven standard model among the actuators. Actuator flex (ACF-1) Designed to compensate for a slight vertical/ horizontal offset. Actuator ACR-1 Radius actuator – for use with small actuating radii. Actuator cross (ACC-1) for vertical / horizontal mounting. Guard locking principles Manual release (standard) Possibility of manually unlocking the switch using a tool – for example for maintenance work. New symbol according to ISO 14119 for the interlocking contact Contacts labelled with this symbol monitor the guard locking position. Since the SLC is a fail-safe guard...

In addition to the manual release, the SLC offers further functions that enable quick intervention if required. Emergency release As a ready-to-use switch or as an accessory, mounted on the front of the SLC, enables immediate opening from outside the dangerous area. Escape release Optionally mounted on the rear of the SLC, the escape release enables immediate opening from within the dangerous area. M20 cable glands Possible on the sides and from below. Optionally available with M12 connector.

SLC sliding handle For robust applications The handle for the SLC combines various functions: • Ergonomic handle to open the door • Prevents lateral forces onto the switch head • Prevents using the switch head as an end stop • Guarantees optimum actuator insertion These properties simplify fault exclusion and enable PL d to be achieved in the door monitoring and locking function. The variant with escape release (BF1-SLC ES) includes an additional handle to be able to open the door from within the danger area when using the function. This requires at least the basic set (ESCR-B). Article...
