EFINITIONS
There are certain terms used throughout this document that serve an important role in describing the
operation and behavior of the AEV & APV STO feature. These terms are discussed and defined as follows:
Activate – This term is used to refer to action taken that results in the safe state being entered. In the
case of the STO feature, the STO function is activated (made active) by making the voltage at one or
both STO inputs less than or equal to the maximum rated de-energize threshold voltage.
De-Activate – This term is used to refer to action taken that results in the safe state being exited. In
the case of the STO feature, the STO function is de-activated (made inactive) by making the voltage at
both STO inputs greater than or equal to the minimum rated energize threshold voltage.
Energize – This term refers to the application of voltage greater than or equal to the minimum rated
energize threshold voltage to an individual STO input. Note that simultaneously energizing both STO
inputs results in the STO function being de-activated.
De-Energize – This term refers to the application of voltage less than or equal to the maximum rated
de-energize threshold voltage to an individual STO input. Note that de-energizing an STO input results
in the STO function being activated AEV-APV UserBoard External
