• ALARM SIGNAL (Optional)
The SEPA
®
fan MF15B05A includes a pulse output, which allows monitoring the correct function of the fan.
The pulse is like a rectangular wave, the frequency correlates to 3x rotor speed. The amplitude is about 5Vss and
appears periodically. At blocked rotor the output signal could be L (≤0,4V) or H (5 V).
IMPORTANT: The pulse output is not protected against short circuit and must not connect to GND or Vcc without pre-
resistor. A pull-up-resistor is needed. Do not connect not used pulse output (insolate).
The fans MF15B05 and MF17B05A have tinned lead wire ends (without connector).
Do not touch the rotor! Please note the handling specification!
