Classification/underlying standards
Category 3
1)
(Cat. 3) according to EN ISO 13849-1
Safety functions
–
SBA
2)
(Safe Brake Actuation): Safe brake actuation with the electromechanical brake
–
SBH
2)
(Safe Brake Hold): Safe brake hold with the electromechanical brake
1)
According to the standard, category 3 requires brake diagnostics of the double brake. This is not part of the double brake and must be realized within the braking system.
2)
Safety functions SBA and SBH were defined by SEW-EURDORIVE in accordance with the standard EN 61800-5-2.
