3.7. Electrical connection 8025 batch controller wall-mount version
To obtain access to the terminals, open the cover. Make connections in accordance with
the following sketches.
Note: The driver unit supply voltage can be used for the binary data inputs and the
indicator lamp output (open collector). In this case the common terminal (10) and the L-
terminal (12) should be connected together.
3.7.1 Connection of flow sensors type 8020/8030
The 8020/8030 transducer is connected as shown in the fig. 3.10

3.7.2 Connection of flow sensor type 8031 "Low Flow" (cf. fig. 3.11)
Refer to the flow sensor documentation in order to select the required voltage supply.
For power supply and output signal connection cf. fig. 3.10 § 3.7.1
with 12...30 VDC power supply of the controller
The flow sensor may be powered with 5...18 VDC, connect terminals 2 (L-) and 4 (L+)
or with 12...30 VDC, connect terminals 2 (L-) and 3 (L+).
with 230/115 VAC power supply of the controller
The flow sensor may be powered with 16 VDC, connect terminals 2 (L-) and 4 (L+)
or with 28 VDC, connect terminals 2 (L-) and 3 (L+).
f the power supply of the sensor is less than 16 VDC, the direct connection of a flow
controller with 115/230 VAC power supply is not possible.
