• ALARM SIGNAL
The SEPA
®
fans HFB44BxxA include 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 appears periodically.
At blocked rotor the output signal could be L (≤0,4V) or H (Vcc).
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 not needed. Do not connect not used pulse output (insolate).
The fans HFB44Bxxx have tinned lead wire ends (without connector).
Do not touch the rotor! Please note the handling specification!
