Testing

NOTICE
Ä Safety sensors must be replaced at the end of their mission time (see chapter 14 "Technical
data").
Ä Always exchange entire safety sensors.
Ä Observe any nationally applicable regulations regarding the tests.
Ä Document all tests in a comprehensible manner and include the configuration of the safety
sensor along with the data for the safety- and minimum distances in the documentation.

Before commissioning and following modifications

Unpredictable machine behavior during start-up 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. The training is the responsibility of
the operating company.
Ä Attach notes regarding daily testing in the respective national language of the operator on the machine
in a highly visible location, e.g. by printing out the corresponding chapter (see chapter 9.3 "Periodically
by the operator").
Ä Test the electrical function and installation according to this document.
Acc. to IEC 62046 and national regulations (e.g. EU directive 2009/104/EC), tests are to be performed by
competent persons (see chapter 2.2 "Necessary competencies") in the following situations:
• Prior to commissioning
• Following modifications to the machine
• After longer machine downtime
• Following retrofitting or new configuration of the machine
Ä As preparation, check the most important criteria for the safety sensor according to the following check-
list (see chapter 9.1.1 "Checklist for integrator – to be performed prior to commissioning and following
modifications"). Completing the checklist does not replace testing by competent persons (see chapter
2.2 "Necessary competencies")!
ð Not until proper function of the safety sensor is ascertained may it be integrated in the control circuit of
the system.
9.1.1 Checklist for integrator – to be performed prior to commissioning and following modifications
NOTICE
Completing the checklist does not replace testing by a qualified person (see chapter 2.2
"Necessary competencies")!
Ä If you answer one of the items on the following check list with no, the machine must no
longer be operated.
Ä IEC 62046 contains additional recommendations on testing protective devices.
Tab. 9.1: Checklist for integrator – to be performed prior to the initial start-up and following modifications
Check:
Is the safety sensor operated acc. to the specific environmental condi-
