Y14 to Y16 monitor outputs for the internal status of the SafetyOne.
Y14 turns ON during Initial state or Stop state.

Y16 turns ON while in the Run state.
Refer to “Chapter 4 BASIC OPERATION”, or “Chapter 6 TROUBLESHOOTING”, for details of
each state.
Warning
Monitor outputs are not safety outputs. Do not use these to construct a safety system.

In the Run state, when the safety outputs are OFF and 1 or more safety inputs are OFF, the
solenoid outputs are ON. When all safety inputs are ON, the solenoid outputs are OFF, although
the start input is not activated.
