2.2 Safety relevant specifications according to
2006/42/EC Machinery Directive
2.2.1 Application
In combination with the elobau safety control units or similar
safety controllers, the safety sensors are exclusively used to
monitor moving, isolating safety devices.
The overall control concept in which the safety sensor is incorpo-
rated, must be validated according to DIN EN ISO 13849-2
standards.
Connecting sensors in series can, under certain circumstances,
reduce their performance level according to EN ISO 13849-1
standards due to a lower detection of errors.
A safety barrier is to be considered when used in intrinsically
safe circuits.
