The Haake HSB® Safety Bumper meets the requirements for automatic reset, since after removing the operating force, it will return by itself into the ON condition. If it is required to work with a manual reset, this has to be implemented according to DIN EN ISO13856-3 by the machine control system. Due to the positive break of the supply (current circuit is broken), a separate safety control unit is not required. Safety Bumper and control system together have to achieve the Performance Level that has been determined in the risk assessment.
Except for dimensions and shapes, the Safety Bumpers have a generally identical design. They contain the following components:
- Haake Safety Contact chain HSC® (opening N/C contacts)
- Carrier plate made of Al, MDF or steel for attaching the bumper at the component to be protected
- Double-insulated connection cables to the machine control system
- Coated PUR foam body, alternatively PUR foam body with protective hood
Pay attention: When using cooling agents, oils, acids etc. or for usage in outdoor applications please contact us for more information.
