• ALARM SIGNAL (Option ...A)
The SEPA
function of the fan. An alarm-board is available on request.
The pulse is like a rectangular wave. The pulse frequency correlates to 2 x rotor speed, OC-output, a pull-
up-resistor is needed. At blocked rotor the output signal could be L (≤0.5V) or H (Vcc).
IMPORTANT: The pulse output is not protected against short circuit and must not connect to GND or
Vcc without series-resistor. Do not connect not used pulse output to GND or Vcc (insolate).
• ACCESSORIES:
ALG01
VARP01
Connector
IMPORTANT: Do not touch the rotor!
• ELECTRICAL PROTECTION:
The MFB40H12xA is permanently protected against false pole of power supply and blocking rotor.
