● Start inputs： X12, X13, X16, and X17
X12 is used to control the start of safety output 1 and 2 as a “control start” which detects welding
of the start switch. X12 is the start input for safety input 1.
X13 is used to control the start of safety output 1 and 2 as an “auto start” which does not use a
start switch, or a “manual start” which does not detect welding of the start switch. X13 is the 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 output 1 as a “control start” which detects welding of the
start switch. X16 is the 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” which detects welding of the
start switch. X17 is the 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 the safety input 1 are in the safe state, and the functional output of
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) the devices connected to
safety inputs 2 and 3 are in the safe state, the functional output of 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) the devices connected to
safety inputs 4 and 5 are in the safe state, and the functional output of self-hold function 3 is
turned ON.
When the functional output of self-hold functions 1 and 2 are ON, the start condition of safety
output 1 is established.
When the functional output of self-hold functions 1 and 3 are ON, the start condition of safety
output 2 is established.
Note: If both X13 and X16, or X13 and X17 are turned ON at the same time, an error is detected.
As the result, the error LED displays “3” and the state changes to the Stop state. Use only 1 of
X13 or X16(X17), but not both at the same time.
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 a dual channel input corresponding to only safety output 1 (namely, safety
inputs 2 or 3) is turned OFF, safety output 1 is turned OFF immediately after the preset time of the
OFF-delay timer, while safety output 2 is turned OFF after the preset time of OFF-delay timer from
the input monitoring error detection time (0.5s).
When 1 contact of the dual channel input corresponding to only safety output 2 (namely, 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
input monitoring error detection time (0.5s).
