Speed control:
By analog voltage 0 - 10 V
Information to the curve analog:
0 V - < 1,3 V: 0 1/min
1,3 V: 800 1/min (Fan on, comming from von 0 V)
1,3 V - 1,6 V: 800 1/min (corresponding to min. speed)
1,6 V - 9,4 V: linear increasing curve
9,4 V - 10 V: 3.400 1/min (corresponding to max. speed)
1,3 V - > 1,0 V: linear decreasing curve (comming from 10 V)
1,0 V: 600 1/min or 0 1/min (Fan off, comming from 10 V)
The fan have no sensor break detection!
Information to the curve:
0 % - 7% PWM: 0 1/min
7 % PWM: 800 1/min (Fan on, comming from 0% PWM)
7 % - 10% PWM: 800 1/min (corresponding to min. speed)
10 % - 90% PWM: linear increasing curve
90 % - 100% PWM: 3.400 1/min (corresponding to max. speed)
7 % - 5 % PWM: linear decreasing curve (comming from 100% PWM)
5 % PWM: 600 1/min or 0 1/min (Fan off, comming from 100% PWM)
3.2 Electrical Operating Data
Measurement
conditions:
Normal air density = 1,2 kg/m3; Temperature 23°C +/ - 3°C; Motor axis horizontal; warm-up
time before measuring 5 minutes (unless otherwise specified).
In the intake and outlet area should not be any solid obstruction within 0,5 m.
Measurement setup: Measured between two steel plates
Steel plate: 180 mm x 180 mm
Intake nozzle: D: 125,5 mm; R: 10 mm
Distance between bottom and top plate: 80 mm
Overlapping impeller / nozzle: 2 mm
∆p = 0: corresp. to free air flow (see chapter aerodynamics)
I: corresp. to arithm. mean current value
