Restart Interlock
When a danger is detected and a control output is turned OFF, a restart interlock prevents a system from restarting by keeping
the safety output OFF status until safety is verified and a reset signal is turned ON.
Setting method
The function is available by wiring terminals.
Connect a reset button between a plus terminal and an X terminal.
The outline of the wiring diagram is as follows:
For details on the wiring, refer to the following:

Operation
When an output is suspended, it is not restarted unless the interlock is disabled.
To disable the restart interlock, current should be applied for all the connected terminals within X0, X1, and X2 after the reset
button is pressed.
For an operation with no restart interlock, when logic in a logic path are all '1', outputs turn ON immediately.
Precautions
• Always connect X0 and X2. Connect X1 depending on the program.
• Rearranging the wiring of X0, X1, and X2 after the settings have been applied will cause an error.
• When wiring the reset button to reset manually, the corresponding X terminal must be open or be connected to a high
resistance output such as a programmable controller. If the potential is HIGH or LOW, a configuration error will occur.
