WARNING
Hazardous condition of the plant
Can Cause Death, Serious Injury, or Property Damage.
The basis of the safety concept is that a safe state exists for all process variables. In the case of
the MSS 3RK3 modular safety system, this is the value "0". This applies to sensors and actuators.
Note that the use of inverting functions either in the logic diagram or in the wiring outside the
system may prevent the safe state from being reached.
