Connecting the sensors
Cables with a minimum cross-section of 2 x 0.5 mm² can be connected to the terminals at the
back panel of the housing.
Connecting the actuators
4
0 to 10 V control output:
Use cables with a minimum cross-section of 2 x 0.5 mm².

Three-step or on/off outputs:
Connect cables with at least 1.5 mm² suitable for damp locations to the terminals of the con-
troller output. The direction of travel needs to be checked at start-up.
Connecting the pumps
Connect all cables with at least 1.5 mm² to the terminals of the controller as illustrated in the wiring
diagram.
CAUTION!
The electric actuators are not automatically supplied with a voltage by the controller. They can
be connected over terminals 25 and 28 to an external voltage source.
If this is not the case, connect a jumper from terminal 18 to terminals 25 and 28.
