2) ø4 push-in joint / ø8 push-in joint is incorporated into FM-□-4(-P) / FM-□-8(-P), respectively. The push-in joint
is not incorporated into the aluminum body type.
2PIPING
● Thefollowingspeciedtubeshouldbeusedtoinserttothepush-injointtypeproduct.
● Beforeusingtheproduct,makesuretocheckthatthetubeisrmlyinserted.
Material of tube Tube diameter Allowable diameter
Polyamid ø4, ø8 Within ±0.1mm
Polyurethane ø4 Within ±0.1mm
ø8 Within +0.1 / -0.15mm
●Installalter,anairdryerandanoilmistlter(micro-alescer)ontotheprimary
side (upstream) of the product since the compressed air from the compressor
contains drain (water, oil oxide and foreign materials, etc.). Mesh (wire net) in the
productisusedtorectifytheowinthepipe.Alwaysinstallaltertotheprimary
sideoftheproductsincethismeshisnotaltertoremoveforeignmaterials,etc.

● Whenusingavalveontheprimarysideoftheproduct,onlyuseanoil-prohibitspecica-
tion valve. The product may malfunction or break if subject to splattering grease or oil, etc.
● Whenusingtheproductwithadsorptionverication,etc.,alwaysinstallanairlter
whoseltrationpropertyis10µmorlessontothesuctionsidetopreventsuction
of foreign materials and water. Furthermore, consider atmospheric dew point and
ambient temperature of the product, use the product under the conditions that
dew condensations will not be formed in the inside of pipe.
● In case of mounting commercial joint to the aluminum body type, apply a spanner on
the metal part of this product and tighten by the tightening torque of 16 to 18N·m. If
excessive torque is applied, the commercial joint or the main body may break.
●When piping, care must be taken that foreign materials such as sealing tape and
adhesive must not enter into the inside. If the foreign materials are entered, the
product may malfunction or break.
● Make sure to mount the joint when using the product with its secondary side (downstream)
isopentotheair.Ifthejointisnotmounted,theportlteroftheproductmayfalloff.
3WIRING
Connection method
●Insert the cable with connector CN-F15-C1 (accesso-
ry) into the connector area of this product and mount
the connector cover.
Disconnection method
● Remove the connector cover and pressing the release
lever of the cable with connector, pull out the connector.
Connector
cover
Note: Do not pull by holding the cable without pressing the release lever, as this can cause cable break or connector break.

Notes: 1) As for the aluminum body type, variable resistor (clamping voltage: approx. 40V) is connected between the
internal power circuit and the metal body to prevent breakdown of the sensor. Connect the metal body to +V
of power supply or frame ground (F.G.) of a device that is connected to 0V. High potential and insulation re-
sistance tests between the internal power circuit and the metal body must not be done.
2) Short-circuit protection is not incorporated into the analogue voltage output.
Do not connect the power supply or capacitive load directly to the analogue voltage output.
6OUTPUT MODE
●The output OFF mode, window comparator mode, hysteresis mode, integrated
output mode or integrated pulse output mode can be selected as the output mode
for comparative output 1 and comparative output 2. Refer to “Output mode and
threshold value setting mode” in “ 8MENU SETTING MODE” for details.
Output OFF mode
●In this mode, the comparative output can always be OFF.

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 2-point input: TurnONtheexternalinputfor80mstoloadtherst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rst
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.

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.

12 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
uids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specicationmaynotbesatisedinastrongmagneticeld.
● Accuracyofthedisplayandtheanaloguevoltageoutputisinuenced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 0.3mm2or 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.
