Operation
The ON/OFF statuses of the contactors connected to Q0 to Q3 are monitored.
When the contactors are ON, no input for X0, X1, and X2 are detected. When they are OFF, inputs for X0, X1, and X2 are
detected.
Precautions
• Always connect X0 and X2 when using this function. 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.
• To monitor contactors that are externally connected to the safety output Q0 to Q3, connect the close contacts of each
contactor to any of the inputs from X0 to X2 in direct connection.
