Electrical connection
Connecting the controller
The controller is connected as illustrated in the following wiring diagrams.
Î
Open the housing to connect the cables.
Î
To connect the feeding cables, make holes in the marked locations at the top, bottom or
back of the base of the housing and fit suitable grommets or cable glands.
Connecting sensors
Cables with a minimum conductor cross-section of 0.5 mm² can be connected to the termi-
nals at the base of the housing.
Connecting actuators
Î
0 to 10 V control output: use cables with a minimum conductor cross-section of 0.5 mm².
Î
Three-step or on/off outputs: connect cables with at least 1.5 mm² suitable for damp lo-
cations to the terminals of the controller output. We recommend checking the direction of
travel at start-up.
Connecting pumps
Î
Connect all cables with at least 1.5 mm² to the terminals of the controller as illustrated in
the wiring diagram.
The electric actuators and pumps are not automatically supplied with a voltage by the con
-
troller. They can be connected over terminals 20, 22, 25 and 28 to an external voltage
source. If an internal power supply is to be used, connect a jumper from terminal 18 to termi
-
nals 20, 22, 25 and 28.
