Datasheet

• Alarm Signal (Optional)
The SEPA
®
MFB60DxxA include a speed impulse output, which enables 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 2 x rotor speed. At blocked rotor the
output signal could be L (≤0.3V) or H (Vcc).
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 permitted.
Do not connect pulse output wire to GND or Vcc (Insolate not used alarm output).
The MFB60Dxx(A) have tinned lead wire ends (without connector).
