10 TEACHING FUNCTION● In this function, sets the threshold value of the comparative output 1 based on theinstantaneous flow rate value at the time of key operation or inputting external sig-nal. For setting the teaching function, refer to “CH2 setting” in “ 9 PRO MODE.”OFF<1-point input, ON when higher than threshold value>Threshold valueThreshold value Threshold valueInput value 1 Input value 2Threshold value 1 Threshold value 2 Threshold value 1 Threshold value 2Input value 1 Input value 2Threshold valueONOFF<1-point input, ON when lower than threshold value>ONOFF<2-point input, ON when higher than threshold value>(Input value 1 + Input value 2) /2 = Threshold value (Input value 1 + Input value 2) /2 = Threshold valueONOFF<2-point input, ON when lower than threshold value>ONOFF<2-point input, ON when within the 2 points>ONOFF<2-point input, ON when out of the 2 points>ONComparativeoutputComparativeoutputComparativeoutputComparativeoutputComparativeoutputComparativeoutputFlow rateFlow rateFlow rateFlow rateFlow rateFlow rateNote: The hysteresis of approx. 1% F.S. (factory setting) is set to the smaller threshold value side. The hysteresis canbe changed in the range of approx. 1 to 8% F.S. For details, refer to “Hysteresis setting” in “ 9 PRO MODE.”[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 AutomaticIn case of 1-point input: Hold down DOWN key for 2 sec. to load instantaneous flowrate 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 inputvalues between 2 points.In case of external inputCH2ON for 80ms(RUN mode) (Display of loading value) (RUN mode)Automatic AutomaticIn case of 1-point input: Turn ON the external input for 80ms to load instantaneousflow 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, loadsthe second input value. The threshold value is set automatical-ly by discriminating the magnitude relation between the firstpoint and the second point. When inputting the third point andthe fourth point successively, the latest input value will be validand 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.11 ERROR INDICATIONError indication Cause RemedyFluid flows during zero-point adjustment. Make sure to check that fluid does not flow andconduct zero-point adjustment again.Internal process errorTurn ON the power supply again. If not restoringnormally, contact Panasonic Industrial DevicesSUNX.Flow rate is exceeding upper limit of thedisplay range. The instantaneous flow rate should be broughtwithin the display flow rate range.Flow rate is exceeding lower limit of thedisplay range.Operation indicatoris blinkingLoad is short-circuited causing an over-current to flow. Turn OFF the power and check the load.12 CAUTIONS● This product has been developed / produced for industrial use only.● This product is for use in air and nitrogen only.

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 (5min. or more after applying current) should be taken when using the product.● Extension up to total 10m is possible with 0.3mm2 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 itmay 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 tocontact each other. If the units are in contact, the heat generated by the productscan cause a change in product characteristics or degradation of the material. Besure to keep a distance of at least 10mm between the products when installingmultiple units.● This product adopts EEPROM. Settings cannot be done 100 thousand times ormore because of the EEPROM’s lifetime.13 SPECIFICATIONS
