Hi, I have a flowsensor FLS F3.10 from ebora < 30 mA at 24 VDC this sensor has a NPN output square form 15 Hz at 1m/s max 10mA I have connected it to I8 of my 6ED1 052-1MD08-0BA0 (3 wire) No pulses are comming in What could be the reason ? ------------------------------------------------------------------------------------------ |

The input I8 is a "normally" digital input for frequencies up to 10 Hz. Your LOGO! has four fast count inputs, I3 - I6. Use one of them. For the electrical wiring see attachment. But by NPN types the signal is negated. Attachment24 VDC sensor with open collector NPN to LOGO! I5.pdf (265 Downloads) |

Hi, great explanation, i changed the resistor to 10K. But stil i see that the M1 is not flashing continuous, somtimes the low time is longer sometimes the high time is loger dan usual. Also i was expecting a higher flow, the pump is rated at 280l/min max and i mesure 83l/min. Even with a high flow resistance i was expecting more than i mesure. Could you check my program ?
