set value input, and which set
value is given with a level of 0-
5V (set value Low) at the set
value input is made here.
„ Fan address
Here, fan group and fan number
can be set. If, for instance,
numerous fans are networked,
they should be connected one
after the other and each of them
should be allocated a unique
address. On the outset, all fans
come factory pre-set (1/1).
„
Input function
Switch between analogous (0-
10V) and digital (0/1) set value
input.

Control parameters / P-, I-
and D-factor
♦
The proportional ratio indicates
how strongly the response is to
a control difference. Level
control is proportional to the
control difference.
♦
Integral proportion: Level
control is proportional to time
integral of the control difference.
Control difference is controlled
to average on a mean time, i.e.
there is no lasting control
deviation.
♦
Differential proportion: Level
control is proportional to the
gradient of the control deviation.
Normally this value is set to 0.
„
Sense of rotation
Running direction of the motor.
„
Maximum speed
Reference speed for scaling
speed.
„
PWM ramp
Defines the period of time that
can elapse between the fan
being switched on and the
maximum speed being reached,
respectively between maximum
speed and fan standstill.
Tab
Information
:
The information given on the tab
depend on the unit being used.
„
Actual control mode
Indicates the operating
mode the fan is currently
in.
„
Control function
Indicates the active effective
direction. However, this only
applies in operating mode
„sensor control“.
„
Sense of rotation
Display of the active direction
of rotation
„
PWM
Display of active minimal and
maximal PWM limiting values.
„
Set value
Indicates the current set value
in the unit corresponding to the
active operating mode.
„
Power
States the approximate current
power consumption of the fan.
„
DC-link voltage
Display of the voltage in Volts
currently applied to the DC-link
of the electronics.
„
DC-link current
Display of the current in
Amperes as currently
measured on the DC-link of the
electronics.
„
Power module temperature
Current temperature of the
output stage of the electronics
in degree Celsius/Centigrade.
