Operation With Default Configuration - Omron FQ User Manual

8-1 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.
Trigger Sensor
(1) Measurement
ON
trigger input
OFF
(TRIG signal)
(2) Executing
ON
measurement
OFF
processing
(BUSY signal)
(3) Judgement results
output (overall
judgement: OR
signal)
Important
• 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.
Power supply
* Depends on the scene data.
Configuring the Operation

Type of change
Changing the type of measurement trigger
