Description of operation
Safety output 1 monitor output

Safety output 1
(Y0, Y1)
Safety output 2 monitor output
(Y13)
Safety output 2
(Y2, Y3)
When the target safety output is ON,
the monitor output is ON. When the
target safety output is OFF, this
function is OFF. The monitor output
turns OFF immediately, independent
of the preset OFF-delay time.
Note. When the safety output detects an output circuit failure, corresponding safety output monitor
output becomes a pulse outputs (1Hz). The monitor output is OFF in other errors, Initial state, or
Configuration state.
●State monitor outputs: Y14 to Y16
State monitor outputs are used to output the internal state of SafetyOne.
