5. Basic settings / connections possible
5.1 Adjustment of the speed by an external potentiometer
The external potentiometer (10 k
Ω
) is connected to the terminals “A” and “GND”. Depending on the setting, a voltage of
0-10 V is returned to the input terminal “E” by the potentiometer pick-off (for 10 V max. output voltage). The connector J
10 (in the terminal compartment) must be inserted in the “up” position, i.e. in position “A”, to do this,(see terminal
connection plan).
J10 “up” position “A” (
factory setting
) = fixed voltage at terminal “A” (+ 10 V for potentiometer)
J10 “down” position “B”
= voltage at terminal “A” = 0-10 V proportional to the motor voltage.
5.2 Adjustment of the speed by an external signal
The external signal for selecting the speed is connected to terminals “E” and “GND” (see terminal connection plan). The
speed of the motors connected is controlled as a direct variance of the signal at the input terminals (for max. 10 V output
voltage).
Subsequent change from 0-10 V to 0-20 mA for the input signal:
Control by a 0-20 mA signal is possible by an external circuit resistor (499
Ω
/ 0.25 W) between the terminals “E” and
“GND”.
5.3 Voltage supply for external equipment
There is an integrated power supply for external equipment. A selection b15 V and +24 V is possible by mean
of jumper J15.
Reference point for voltage = next GND-terminal, max. 20 mA
J15 up position “A“ +15 V
output voltage ± 5 %.
J15 down position “B“ +24 V (
standard setting
)
output voltage ± 20 %.
The voltage stabilisation function for the motor voltage is limited for a load on this voltage
supply. Thus this must be interrupted in the terminal compartment by connector J 3 (

5.4 Running several fans from one controller
Several fans can be connected to the controller. The maximum total current of all motors (maximum rated current for
electronic control of the voltage) must not exceed the current rating of the controller.
If the maximum control current for the electronic voltage control is not known, then allowance for an increase up to 20 %
in the motor nominal current must be made.
For the control of motors made by other manufacturers (not Ziehl-Abegg), the control characteristics and the maximum
current for electronic regulation of the voltage should be enquired from the manufacturer.
It is recommended that a separate motor surveillance unit (e.g. S-ET10) is foreseen for each fan.
