●Safety input monitor outputs: Y4 to Y11 
Safety input monitor outputs are used to output the status of safety inputs in SafetyOne. 
Intended outputs 
(Terminal names) 
Target safety inputs and 
muting inputs 
(Terminal names) 
Description of operation 
Safety input 1 monitor output 
(Y4) 
Safety input 1 
(X0, X1) 
Muting input 1 monitor output 
(Y5) 
Muting input 1 
(X2, X3) 
Safety input 2 monitor output 
(Y6) 
Safety input 2 
(X4, X5) 
Muting input 2 monitor output 
(Y7) 
Muting input 2 
(X6, X7) 
Safety input 3 monitor output 
(Y10) 
Safety input 3 
(X10-T10, X11-T11) 
Safety input 4 monitor output 
(Y11) 
Safety input 4 
(X12-T12, X13-T13) 
When the target safety input or 
muting input is ON, the monitor 
output is ON. When the target 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 and Y13 
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 monitor output 
(Y12) 
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, the corresponding safety output monitor 
output becomes a pulse output (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.

Refer to “Chapter 4 BASIC OPERATIONS” and to “Chapter 6 TROUBLE SHOOTING” for details of 
each state. 
Warning
The monitor outputs are not safety outputs. Do not use these to construct a safety system.
