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.
