Kistler's new SPLe Type 2154"¦ safety module makes it easier for users of the company's electromechanical NC joining systems on semi-automatic assembly stations to achieve performance level e (PL e) as defined in EN ISO 13849-1 Safety of machinery - Safety-related parts of control systems.
The safety module SPLe Type 2154"¦ is designed for use with NC joining systems in semi-automatic stations and manual workstations with hand loading, whose safety requirements are particularly stringent. Where speeds of more than 10mm/s are used (and where the speed cannot be reliably reduced), performance level e is required in order to reduce the risk of injury.
The new safety module is suitable for use with Kistler's 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 4740A"¦ and the established DMF-P A300 NCF Type 4734A... When used in combination with the NC joining module NCFH Type 2151B"¦ that features a hollow-shaft motor instead of a belt drive, the overall result is a particularly compact joining/monitoring system.
Kistler says that 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 enable performance level e to be attained.
In Kistler's TÜV-assessed system, the module is linked with a safety device by means of two normally-closed contact inputs. This provides for 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.
