The type of activation is set by 6 DIP switches on the SmartBoard in accordance with the wiring diagram and system config-
uration.

Control via 0 - 10 VDC
The 0-10 VDC control signal at input terminals AI2 and GND (Ri = 20 kOhm) on the SmartBoard is interpreted for speed and
valve control according to the following values:
Control signal
Function
0 - 3 V
Unit "Off"
3 - 9 V
Valve "Open"
4 - 9 V
Fan speed min. ... 100%
A maximum limit can be set via the potentiometer on the SmartBoard.
Output terminals V1 and GND are available on the SmartBoard to activate a 24 VDC open/close actuator. Maximum permiss-
ible load 0.5 A.
A non-floating fault message 24 VDC/max. 0.5 A is available at terminals V2 and GND after appropriate parametrisation with
an additional KaController. Any EC fan fault is signalled to the KaControl system and the red LED in the housing illuminates.
Voltage supply and fusing
EC fan and KaControl recirculation air module are supplied together with 230 V/50 Hz voltage via a supply line. An operating
indicator LED is located on the terminal circuit board in the KaControl module. Also installed on the terminal circuit board is a
unit fuse Ø5 x 20 mm on the primary side for the control voltage, as well as on the secondary side for the 24 V voltage and a
unit fuse Ø5 x 20 mm on the SmartBoard.
