| | | The SEPA"' mfb30exxa includes a pulse output, which allows monitoring the correct function of the fan. An alarm-board is available on request. The pulse Is like a rectangular wave, the frequency correlates to 3 x rotor speed. At blocked rotor the output signal could be L or H (mfb30e05a: 0.5/3.7v, mfb30e12: 1.0710.7v). important: The pulse output is not protected against short circuit and must not connect to gnd or Vcc without series-resistor. a pull-up-resistor is not needed. Do not connect not used pulse output to GND or Vcc (insulate). | | |
