●Start inputs: X16 and X17
X16 is used to control the start of the safety outputs as an “auto start” which does not use the start
switch, or “manual start” which does not detect welding of the start switch. When the start input
(X16) is turned ON (the ON state of X16 must be received for over 0.1s) during which all devices
connected to the safety inputs are in safe state, the start condition is established.
X17 is used to control the start of the safety outputs as a “control start” which detects welding of
the start switch. When the start input transmits OFF→ON→OFF (the ON state of X17 must be
received for between 0.1s to 5s) during which all devices connected to the safety inputs are in the
safe state, and then the start condition is established.
Note: If both of X16 and X17 are turned ON, the SafetyOne will detect an error. As the result, the
error LED displays “3” and the state changes to the Stop state. Use either X16 or X17, but not
both.
●Safety outputs (with OFF-delay timer): Y0 to Y3
Y0 to Y3 function as safety outputs with the OFF-delay timer. When the timer is set to “0s”
(indication “1”), the safety outputs are shut OFF immediately.
Y0 and Y1: Safety output 1
Y2 and Y3: Safety output 2
● Safety input monitor outputs: Y4 to Y11
Y4 to Y11 function as status monitors of the safety input devices connected to the SafetyOne.
Y4 to Y7: When safety devices are connected to X0 to X7 (T0 to T7), the output is ON while the
contacts connected to X0, X2, X4, and X6 are OFF and while the contacts connected to X1, X3,
X5, and X7 are ON.
Y10 and Y11: When the both contacts of the safety device connected to safety output 5 and 6 are
ON, the output is ON. When both contacts are OFF, the output is OFF.
If an input monitor error is detected, pulses of (1Hz) are 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).
Y11 outputs the status of safety input 6 (X12-T12, X13-T13).
●Safety output monitor 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 the
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 1 (Y2 and Y3). This turns ON when Y2 and Y3 are both
ON.
