Current vs Ambient Temperature 0 30 35 40 45 50 55 Ambient Temperature (°C) The control behaviour can be easily described by looking at the function of output voltage versus input pressure: In the maximum range the FSY provides a constant output voltage of approximately 1% below the supply voltage. The fan is running at maximum speed. Along the proportional range the output voltage varies between maximum and minimum voltage of approximately 45% of the supply voltage. This causes the fan to slow down from maximum to minimum speed. Pressure change FSY-41: 4,0 .. 12,5 bar per turn of clockwise ~ +1.2 bar adjustment screw counter clockwise ~ –1.2 bar FSY-42: 9,2 .. 21,2 bar clockwise ~ +2.5 bar counter clockwise ~ –2.5 bar FSY-43: 12,4 .. 28,4 bar clockwise ~ +3.3 bar counter clockwise ~ –3.3 bar Proportional Range FSY-41: 2,5 bar FSY-42: 3,8 bar FSY-43: 4,6 bar Weight approx.

Reincrease of input pressure will start the motor with a hysteresis of approximately 0.7 bar to avoid cycling. The pressure from which motor cuts off is adjustable (see pressure range). 99
