8.7 Example of use

Safety-related monitoring of two sensor circuits with primary PLC or machine control.
For a functional test of the protection, the PLC/machine control performs a test prior to each dangerous
movement or in the non-dangerous phase/movement of the machine. If the test result is correct, the
PLC/machine control then initiates the movement or the next work step.

8.8 Functional test

The plant / machine must be tested for proper function after all of the electrical connections have
been established and the supply voltage has been turned on.
To do this, activate each of the sensors in sequence and check the corresponding reactions of the
switching unit.
The safety system is to be professionally inspected at appropriate intervals and be documented in
such a way that it is comprehensible at all times. The requirements of the plant or machine manuf-
acturer are to be taken into account and followed.
