Not only must the output be safe, but also the complete wiring and surroundings. In order to reach cat. 4 of functional
safety, two outputs must be wired as a pair, so that a defect of one output cannot cause a total loss of safety, as the other
one of the pair is still able to switch o the dangerous parts of the plant (or machine). So wiring similar to the following
has to be done:
6.4.1 Outputs function
A
The NO safety outputs switch on (contact closes) when the
safety inputs are active and the start/reset is pressed.
B
In case of intervention of the safety inputs, the NO safety
outputs are switched o
C
If the power supply fails, the NO safety outputs are switched

Information:
You must comply with the safety-related parameters in order to ensure the required safety level for your
plant/machine. All the units which use a safety function must be considered when calculating the overall
safety level.
