WARNING!

Muting the safety function

A valid signal at the OR input of a PNOZelog unit mutes its safety function
and can lead to the most serious injuries and death.

– Before using the OR function, carry out a risk analysis and use other

measures to establish a safe condition.

The following examples represent various ways in which PNOZelog units can be logically
connected. In all the application examples, 2 loads may also be connected to the safety
outputs.
