Wiring of the pulse output in PNP mode
(*) If direct earthing is not possible, insert a 100 nF / 50 V condensator between the negative terminal of the voltage supply and the earth.

glands
Connect the relays according to chap. "8.4.2".
8.5. Connecting the flow sensor to the 8025 transmitter, panel-
mounted version or wall-mounted version
Configure the FLOW SENSOR selector on the electronic board (see chap. "8.3").
Connect the remote flow sensor to the FLOW SENSOR terminal block of the electronic board by respecting the pin
assignment depending on the output type of the remote sensor, either sinus (COIL) or pulse output (NPN).
