8-1 Controlling/Outputting in Parallel
Operation with Default Configuration
This section describes the basic connections and signal flow with external devices.
With the default settings, the Sensor operates in the following manner.
• Create the ladder program to control the TRIG and IN5 input signals so that they do not turn ON while the BUSY
signal is ON. If not, a TRIG input error will occur and the ERROR signal will turn ON.
• Operation When the Sensor Power Supply Is Turned ON
The BUSY signal will operate as shown below when the Sensor’s power supply is turned ON.
Create the ladder program in the PLC or other external device so that the BUSY signal is ignored while it turns OFF,
ON, and OFF again for up to 5 s after the power supply is turned ON.
* Depends on the scene data.
