Regularly by qualified persons
The reliable interaction of safety sensor and machine must be regularly tested by qualified persons (see
chapter 2.2 "Necessary competencies") in order to detect changes to the machine or impermissible tamper-
ing with the safety sensor.
Acc. to IEC/TS 62046 and national regulations (e.g., EU directive 2009/104/EC), tests of elements which
are subject to wear must be performed by qualified persons (see chapter 2.2 "Necessary competencies") at
regular intervals. Testing intervals may be regulated by nationally applicable regulations (recommendation
acc. to IEC/TS 62046: 6 months).
Ä
Only allow testing to be performed by qualified persons (see chapter 2.2 "Necessary competencies").
Ä
Observe the nationally applicable regulations and the time periods specified therein.
Ä
As preparation, observe the checklist (see chapter 9.1 "Before the initial start-up and following modifi-
cations").
9.3
Periodically by the operator
The function of the safety sensor must be checked depending on the given risk according to the following
checklist so that damages or prohibited tampering can be detected.
Depending on the risk assessment, the test cycle must be defined by the integrator or operating company
(e.g., daily, on shift changes, ...) or is specified by national regulations or regulations of the employer's lia-
bility insurance association and may be dependent on the machine type.
Due to complex machines and processes, it may be necessary under certain circumstances to check some
points at longer time intervals. Observe the classification in “Test at least” and “Test when possible”.
NOTICE
For larger distances between transmitter and receiver and when using deflecting mirrors, a sec-
ond person may be necessary.
WARNING
Unpredictable machine behavior during the test may result in serious injury!
Ä
Make certain that there are no people in the danger zone.
Ä
Before they begin work, train the operators on their respective tasks and provide suitable
test objects and an appropriate test instruction.
