Flow Sensor (Input selection)
(ON level)

(Input filter)
Flow sensor judgment can be used for slow flowrate stop, dry pump detection and end of
curve detection. The flow sensor uses digital signal ON (flowing) and OFF (not flowing) as
detection results. The flow sensor can be used for detection with either a digital input or an
analog input. If not set, the flow sensor is taken to be OFF.
If the flow sensor is set with a digital input, the digital input
FS is the flow sensor.
If the flow sensor is set with an analog input, the results of comparing the analog value
selected for the flow sensor (input selection) (J163) and flow sensor (ON level) (J164), (OFF
level) (J165) becomes the flow sensor.

„ Flow sensor (ON level) (J164), (OFF level) (J165)
If the flow sensor is set with an analog input, the flow sensor ON/OFF levels are set. If the
analog input value exceeds the flow sensor (ON level) (J164), the flow sensor is recognized
as ON. If the analog input value is below that of the flow sensor (OFF level) (J165), the flow
sensor is recognized as OFF.
- Data setting range: 0.00 to 9990.00, OFF (Setting range is limited by maximum scale and
minimum scale.)
„ Flow sensor (Input filter) (J166)
Sets the input filter if flow quantity switches are connected to terminals X1 to X7. If the flow
sensor has an analog input, this filter does not work.
Please set the flow switch FS (data = 131) to function codes E01 to E07.
- Data setting range: 0.00 to 5.00 (s)
