●Safety input monitoring outputs: Y4 to Y10
Y4 toY10 function as status monitoring of safety input devices connected to the SafetyOne.
When both contacts of the safety device are ON, the output is ON. When the both contacts are
OFF, the output is OFF.
If an input monitoring error is detected, a pulse (1Hz) is transmitted.
Y4 outputs the status of safety input 1 (X0-T0, X1-T1).
Y5 outputs the status of safety input 2 (X2-T2, X3-T3).
Y6 outputs the status of safety input 3 (X4-T4, X5-T5).
Y7 outputs the status of safety input 4 (X6-T6, X7-T7).
Y10 outputs the status of safety input 5 (X10-T10, X11-T11).
●Safety output monitoring outputs: Y12 and Y13
Y12 and Y13 function as monitoring outputs that output the status of the safety outputs. When the
safety outputs are OFF, the safety output monitor output is turned OFF immediately, even if
OFF-delay timer has been set.
Y12 outputs the status of safety output 1 (Y0 and Y1). This turns ON when Y0 and Y1 are both
ON.
Y13 outputs the status of safety output 2 (Y2 and Y3). This turns ON when Y2 and Y3 are both
ON.
●State monitoring outputs: Y14 to Y16
Y14 to Y16 are monitoring outputs for the internal status of the SafetyOne.
Y14 turns ON when in Initial or Stop state.
Y15 turns ON in Initial, Protection or Configuration state.
Y16 turns ON when in Run state.
Refer to “Chapter 4 BASIC OPERATION”, or “Chapter 6 TROUBLESHOOTING”, for details of the
each state.
Warning
Monitoring outputs are not safety outputs. Do not use these to construct a safety system.
●Solenoid outputs: Y17 and Y20
Y17 and Y20 are outputs for solenoid control that are used for safety switch with a solenoid lock.
In the Run state, when the safety outputs are OFF and 1 or more safety inputs are OFF, the
solenoid outputs are turned ON. When all safety inputs are ON, the solenoid outputs are turned
OFF, although the start input is not activated.
Warning
Solenoid outputs are not safety outputs. Do not use these to construct a safety system.
Caution
Refer to "Chapter 2 PRODUCT SPECIFICATIONS" for specifications of each input and output.
