Safety Module SPLe as Option for Electromechanical NC Joining Systems

Play it Safe with Kistler for Semi-automatic Assembly Stations:

The new safety module SPLe Type 2154… makes it easier for users of Kistler's electromechanical NC joining systems to achieve the highest of four categories on semi-automatic assembly stations. This ensures performance level (PL) e as defined in the new EN ISO 13849–1 Safety of machinery – Safety-related parts of control systems. Operators of workstations with manual loading or unloading are ensured maximum protection with the safety module meeting the latest safety requirements.

The SPLe is ideal for use of NC joining systems in semi-automatic stations and manual workstations with hand loading, whose safety requirements are particularly stringent. At speeds of more than 10 mm/s that are not reliably reduced, these stations require achievement of a performance level of e. EN ISO 13849-1 states that equipment with this performance level makes a large contribution to risk reduction.

The safety module is designed for use with electromechanical NC joining modules NCFN Type 2153A…, NCFT Type 2157A…, NCFH Type 2151B… or NCFB Type 2160A… with holding brake. It can be combined with both the new force-displacement evaluation unit DMF-P A310 Universal Type 4740… and the established DMF-P A300 NCF Type 4734... Combination with the NC joining module NCFH Type 2151B… featuring a hollow shaft motor instead of a belt drive gives rise to a particularly compact solution.

The safety concept includes a reliably reduced speed to performance level d as standard. In conjunction with the integral safety technology of the Bosch-Rexroth IndraDrive with S2 option (PL d), the safety module uses the SS1ES function with reliably monitored stopping to allow attainment of performance level e.

In Kistler's TÜV-assessed solution, the module is linked with a safety device by means of two normally closed contact inputs. This allows effective protection of the operator through the use of two-hand starting devices or light curtains. The customer is responsible for providing a reliable lock/interlock system if a safety door is used.
