• The response time to the status of the machine STOP, including the response time of
the light curtain and machine, is within the limit values defined for calculating the safety
distance (see Chapter 2.2).

details specified in Chapter 2.2.
• Access and exposure of persons between the light curtain and hazardous machine
components is prevented.

• In order to guarantee that the light curtain remains in NORMAL FUNCTION MODE for at
least 10-15 minutes and, after positioning the specific test object in the protected field,
stays in a SAFE STATE for the same time span, there must be no interference from
external light sources.
