Testing

WARNING
A running machine may result in serious injury!
 Make certain that, during all conversions, maintenance work and inspections, the system is securely
shut down and protected against being restarted again.
The safety relays must be exchanged after a maximum of 20 years.
 Always exchange the entire safety relay.
 For the tests, observe nationally applicable regulations.
 Document all tests in a comprehensible manner.
9.1

Before the initial start-up and following modifications

Acc. to IEC/TS 62046 and international regulations (e.g. EU directive 2009/104/EG), tests are to be
performed by competent persons in the following situations:
• Prior to the initial start-up
• Following modification to the machine
• After longer machine downtime
• After retrofitting or reconfiguring the safety device (safety relay and/or safety sensors)
WARNING
Unpredictable machine behavior during initial start-up may result in serious injury!
 Make certain that there are no people in the danger zone.
 Test the effectiveness of the shutdown function in all operating modes of the machine acc. to the corre-
sponding checklist (see chapter 9.1.1 „Checklist – initial start-up").
 Document all tests in a comprehensible manner and include the configuration of the safety relay along
with the data for the safety and minimum distances in the documentation.
 Before they begin work, train the operating personnel on their respective tasks. The training is the
responsibility of the operating company.
 Check whether the safety relay was correctly selected acc. to the locally applicable regulations and
directives.
 Check whether the safety relay is operated acc. to the specified environmental conditions (see
chapter 13 „Technical data").
 Make certain that the safety relay is protected against overcurrent.
 Perform a visual inspection for damage and test the electrical function (see chapter 9.2 „To be per-
formed periodically by a competent person").
Minimum requirements for the power supply unit:
• Safe mains separation.
• Power-failure bridging for at least 10 ms.
Not until proper function of the optoelectronic safety device and the safety relay is ascertained may they
be integrated in the control circuit of the system.
