[How to load the reference instantaneous flow rate value]
In case of key operation
(RUN mode)
(Display of loading value)
(RUN mode)
Hold down for 2 sec.
/
Automatic
Automatic
In case of 1-point input: Hold down DOWN key for 2 sec. to load instantaneous flow
rate value and set threshold value.
In case of 2-point input: Hold down UP key and DOWN key for 2 sec. to load the in-
put values of 2 points. The threshold value is set automati-
cally by discriminating the magnitude relation of the input
values between 2 points.
In case of external input
CH2
ON for 80ms
(RUN mode)
(Display of loading value)
(RUN mode)
Automatic
Automatic
In case of 1-point input: Turn ON the external input for 80ms to load instantaneous
flow rate value and set threshold value.
In case of 2-point input: Turn ON the external input for 80ms to load the first input val-
ue. When turning ON the external input again for 80ms, loads
the second input value. The threshold value is set automatical-
ly by discriminating the magnitude relation between the first
point and the second point. When inputting the third point and
the fourth point successively, the latest input value will be valid
and the threshold value is set. The default loading value is 0.
Notes: 1) The threshold value set at the teaching function will be reset when turning ON the power again.
2) Loads the instantaneous flow rate value to the comparative output 1 by teaching.
After the load is complete, ON / OFF pulses (approx. 40ms) are outputted after approx. 6 sec. at 1-point in-
put, approx. 10 sec. at 2-point input.

ERROR INDICATION
Error indication
Cause
Remedy
Fluid flows during zero-point adjustment.
Make sure to check that fluid does not flow and
conduct zero-point adjustment again.
Internal process error
Turn ON the power supply again. If not restoring
normally, contact Panasonic Industrial Devices
SUNX.
Flow rate is exceeding upper limit of the
display range.
The instantaneous flow rate should be brought
within the display flow rate range.
Flow rate is exceeding lower limit of the
display range.
Operation indicator
is blinking
Load is short-circuited causing an over-
current to flow.
Turn OFF the power and check the load.

CAUTIONS
● This product has been developed / produced for industrial use only.
● This product is for use in air and nitrogen only. Do not use the product for other
fluids since the sensing accuracy cannot be guaranteed.
● Take care that if foreign materials are mixed in the sensing part, the product may break.
● Do not use this product for commercial purposes since the product does not com-
ply with International System of Units (SI).
● Do not apply pressure that is exceeding resistant-pressure.
● Make sure that the power supply is OFF while wiring.
● Take care that short-circuit of the load or wrong wiring may burn or damage the product.
● Take care that if applying voltage exceeding the rated range or connecting to AC
power supply, the product may break or burn.
● If power is supplied from a commercial switching regulator, ensure that the frame
ground (F.G.) terminal of the power supply is connected to an actual ground.
● In case noise generating equipment (switching regulator, inverter motor, etc.) is
used in the vicinity of this product, connect the frame ground (F.G.) terminal of the
equipment to an actual ground.
● Do not use during the initial transient time (approx. 5 sec.) after the power supply is switched ON.
● Do not run the wires together with high-voltage lines or power lines or put them in
the same raceway. This can cause malfunction due to induction.
● The specification may not be satisfied in a strong magnetic field.
● Accuracy of the display and the analogue voltage output is influenced by self-heat-
ing by applying current other than the temperature characteristics. Standby time (5
min. or more after applying current) should be taken when using the product.
● Extension up to total 10m is possible with 0.3mm
2
or more, cable.
● Make sure that stress by forcible bend or pulling is not applied directly to the sen-
sor cable joint.
● This product is suitable for indoor use only.
● Do not use this product in places having excessive vapor, dust, etc., or where it
may come in contact with corrosive gas, etc.
● Take care that the product does not come in contact with water, oil, grease, or or-
ganic solvents such as thinner, etc., strong acid or alkaline.
● Do not drop the product or apply hard shock. This can cause product breakage.
● In the case multiple units are installed next to each other, do not allow them to
contact each other. If the units are in contact, the heat generated by the products
can cause a change in product characteristics or degradation of the material. Be
sure to keep a distance of at least 10mm between the products when installing
multiple units.
● This product adopts EEPROM. Settings cannot be done 100 thousand times or
more because of the EEPROM’s lifetime.

Notes: 1) Converted to volumetric flow at +20°C and 1 atmospheric pressure (101kPa).
2) The display flow rate range is the case when setting to bi-direction at the flow direction setting. When the flow
direction is set to one-side forward direction or one-side reverse direction, the negative side of the display
flow rate range shows up to 10% of the full-scale (F.S.).
3) Take care that if fluid flows in the vicinity of zero-point which is out of the accuracy assurance range, the in-
stantaneous flow rate value may forcibly display “zero”, or the integrated value may not be counted, or the in-
tegrated pulse output may not be outputted.
4) The clean air complies with JIS B 8392-1.1.1 to 5.6.2 and the compressed air complies with JIS B 8392-1.1.1
to 1.6.2.
5) As a variable resistor (clamping voltage: approx. 40V) is connected to the aluminum body type, do not apply
voltage higher than the rated voltage of the sensor.
