● Start inputs： X12, X13, X16, and X17
X12 is used to control the start of safety outputs 1 and 2 as a “control start” that detects welding of
the start switch. X12 is a start input for safety input 1.
X13 is used to control the start of safety outputs 1 and 2 as an “auto start” which does not use the
start switch, or a “manual start” which does not detect welding of the start switch. X13 is a start
input for safety inputs 2, 3, 4, and 5. X13 is used for a partial stop function.
X16 is used to control the start of safety outputs 1and 2 as a “control start” that detects welding of
the start switch. X16 is a start input for safety inputs 2 and 3. X16 is a partial stop function.
X17 is used to control the start of safety output 2 as a “control start” that detects welding of the
start switch. X17 is a start input for safety inputs 4 and 5. X17 is used for a partial stop function.
When X12 changes from OFF→ON→OFF (the ON state of X12 must be on between 0.1s to 5s)
while the devices connected to safety input 1 are in the safe state, the function output of the
self-hold function 1 is turned ON.
When X13 is ON (the ON state of X13 must be on greater than 0.1s) or X16 changes from
OFF→ON→OFF (the ON state of X16 must be on between 0.1s to 5s) while the devices
connected to safety inputs 2 and 3 are in safe state, the function output of the self-hold function 2
is turned ON.
When X13 is ON (the ON state of X13 must be on greater than 0.1s) or X17 changes from
OFF→ON→OFF (the ON state of X17 must be on between 0.1s to 5s) while the devices
connected to safety inputs 4 and 5 are in the safe state, the function output of the self-hold
function 3 is turned ON.
When the functional output of the self-hold function 1 and 2 are ON, the start condition of the
safety output 1 are established.
When the functional output of the self-hold functions 1, 2, and 3 are ON, the start condition of
safety output 2 is established.
Note: If both sets of X13 and X16, or X13 and X17 are turned ON at the same time, the SafetyOne
will detect an error. As a result, the error LED displays “3” and the state changes to the Stop state.
Use only 1 set of X13 or X16(X17) at a time and never use both together.
Note: Do not use T12 and T13.
●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
Warning
When 1 contact of the dual channel input corresponding to safety output 2 (safety inputs 4 or 5) is
turned OFF, safety output 2 is turned OFF immediately after the preset time of the OFF-delay
timer, while safety output 1 is turned OFF after the preset time of OFF-delay timer from the input
monitoring error detection time (0.5s).
