Periodically by the operator
The function of the safety relay must be checked depending on the given risk according to the following
checklist so that damage 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 of the safety sensor and when using de-
flecting mirrors, a second 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.

Before they begin work, train the operators on their respective tasks and provide suitable
test objects and an appropriate test instruction.
