Testing
CAUTION
It may be the case that safety parameters are no longer met after the mission time.
The safety parameters can no longer be guaranteed for sensors that are used beyond the mis-
sion time.
Ä
Safety sensors must be replaced at the end of their mission time (see chapter 12 "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.
8.1
Before commissioning and following modifications
WARNING
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 8.3 "Periodically
by the operator").
Ä
Test the electrical function and installation according to this document.
Acc. to IEC/EN IEC 62046 and national regulations (e.g. EU directive 2009/104/EC), tests are to be per-
formed by competent persons (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 8.1.1 "Checklist for integrator – to be performed prior to commissioning and following
modifications"). Completing the checklist does not replace testing by competent persons (Necessary
competencies)!
ð
Not until proper function of the safety sensor is ascertained may it be integrated in the control circuit of
the system.
8.1.1
Checklist for integrator – to be performed prior to commissioning and following modifications
NOTICE
Completing the checklist does not replace testing by a qualified person (Necessary com-
petencies)!
Ä
If you answer one of the items on the following check list with
no
, the machine must no
longer be operated.
Ä
IEC/EN IEC 62046 contains additional recommendations on testing protective devices.
