Air Flow Sensor D6FZ-FGT
It's possible to assign judgment of TH1-TH4 to 2 outputs. During output, display’s output
indicator is turned on. The output follows the output setting.

Air Flow Station D6FZ-FGX21
If the Air Flow Sensor measured value is more than Hi threshold, and between Cut and Lo
threshold during RUN operation, the Air Flow Station's alarm output terminal turns ON and
the "ALM" indication on the display turns ON.
If the measured value of any connected Air Flow Sensor unit is outside the threshold range,
the alarm output terminal turns ON.

Function/Operation
NN.HI
Air Flow Sensor upper
threshold value
Specifies the Air Flow Sensor upper
threshold value for alarm output.
NN.LOW
Air Flow Sensor lower
threshold value
Specifies the Air Flow Sensor lower
threshold value for alarm output.
NN.CUT
Leak detection flow
rate
The threshold value for zero flow rate
and specified between the lower
threshold and zero flow rate values.
HOLD
Alarm hold setting
Specifies if the alarm output is held
when a measured value outside the
upper and lower threshold range (Alarm
status) returns to a normal value within
the range during RUN operation.
