Max. ambient temperature [°C] see data sheet, available in our online catalogue.
Max. temperature of transported air [°C] see data sheet, available in our online catalogue.
Sound pressure [dB] see data sheet, available in our online catalogue.
Voltage, current, frequency, enclosure class, weight see name plate of the fan
The motor data can be found on the name plate of the motor, or in the technical documents of the motor
manufacturer.

Table 2 CO control unit components
Component Function
Fan
Two fans with a 0-10 V control input and hall output, for ventilation of the
room being monitored.
CO sensor
CO sensor with 4…20 mA measuring signal output that reflects a 0…300
ppm CO concentration.
External alarm device (optional) Connection of an alarm siren or alarm light
The CO control unit controls two EC fans with a 0–10 V control signal originating from a CO sensor. Both fans are con-
trolled with the same 0–10 V signal and monitored for fan failure. The CO alarm is triggered based on the threshold and
time specifications of DIN EN 50291-1.
