5.5 Information about MRL 2006/42/EC

Machinery directive (MD) 2006/42/EC is effective starting 2009-12-29 (without a transitional period). This directive
requires all machines and
monized standards.
For handheld control devices from B&R, this means that in addition to the new guideline, standard
13849-1:2008 is also specified
requires the category and performance level (PL) to be specified for the safety-relevant "enable switch" component
as well as the B value for the gray stop switch. These values are specified in section
10d
129 or "Enable switch" on page

5.5.1 Which devices have to satisfy the new MD?

Valid for B&R as well as for our customers:
• The date of applicability of the directive depends on the date the product was brought into circulation. If the

into circulation, even if it was sold by B&R at an earlier date.
• Devices in accordance with the old MD that are received by B&R for repairs
returned according to the old MD.
