Parallel control of several speed controllers / EC-fans
The maximum possible number of speed controllers / EC fans with 0...10 V input that
can be controlled parallel depends on their input resistance and on the maximum
admissible load of the 0...10 V output.
Example:
•
Supply voltage CPG / CTG: 10 V => I
max
for 0...10 V output =
0.3 mA
(see Technical
data or connection diagram).
•
ECblue motor size B: Input resistance R
i
>
100 k
Ω
(Assembly instuctions fan
seeTechnical data or connection diagram).
•
The current consumption for one fan is max.
0.1 mA
(I = U / R = 10 V / 100 k
Ω
)
✓
Result:
A maximum of
three
ECblue motor size B can be operated in parallel at one CPG /
CTG (total current consumption
≤
I
max
0...10 V output CPG / CTG).
Attention!
•
It is not permissible to connect outputs of several devices to each other!
•
In case of failure of the control module or interruption of the 0...10 V speci
fi
cation
signal, all parallel connected EC fans/speed controllers are no longer controlled. This
means that all fans stop!
5.5 Digital input (D1)
Different functions can be assigned to the digital input D1(see IO SETUP).
