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.
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 specification signal, all parallel connected EC fans/-
speed controllers are no longer controlled. This means that all
fans stop!
5.4 Input for switch over Setpoint 1/ 2
Via voltage at terminals "1" and "2" (10... 24 V DC) a switchover
between Setpoint 1 and Setpoint 2 is possible (note polarity see
connection diagram).
Voltage OFF => Setting "Setpoint 1" active
