●Safety input monitor outputs: Y4 to Y10
Safety input monitor outputs are used to output the status of safety inputs in SafetyOne.
Intended outputs
(Terminal names) Target safety inputs
(Terminal names) Description of operation
Safety input 1 monitor output
(Y4) Safety input 1
(X0-T0, X1-T1)
Safety input 2 monitor output
(Y5) Safety input 2
(X2-T2, X3-T3)
Safety input 3 monitor output
(Y6) Safety input 3
(X4-T4, X5-T5)
Safety input 4 monitor output
(Y7) Safety input 4
(X6-T6, X7-T7)
Safety input 5 monitor output
(Y10) Safety input 5
(X10-T10, X11-T11)
When the target safety input is ON,
the monitor output is ON. When the
target safety input is OFF, the
monitor output is OFF.
Note. When the targeted safety input detects an input monitor error, input circuit failure, or EMC the
disturbance, corresponding safety input monitor output becomes a pulse output (1Hz). The
monitor output is OFF in other errors, Initial state, or Configuration state.
●Safety output monitor outputs: Y12, Y13, Y17, and Y20
Safety output monitor outputs are used to output status of safety outputs in SafetyOne.
Intended outputs
(Terminal names) Target safety outputs
(Terminal names) Description of operation
Safety output 1-1 monitor output
(Y12) Safety output 1-1
(Y0)
Safety output 1-2 monitor output
(Y13) Safety output 1-2
(Y1)
Safety output 2-1 monitor output
(Y17) Safety output 2-1
(Y2)
Safety output 2-2 monitor output
(Y20) Safety output 2-2
(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, the corresponding safety output
monitor output becomes a pulse output (1Hz). The monitor output is OFF in other errors,
Initial state, or Configuration state.
