The wiring of the current output and the wiring of the pulse output of the panel or wall-mounted transmitter, 12-36 V DC,
without relays, are the same as for a compact flowmeter, 12-36 V DC, without relays, with cable glands.
→ Wire the current output according to "Fig. 28" of chap. "8.4.3".
→ Wire the pulse output according to "Fig. 29" of chap. "8.4.3".
8.6.2. Wiring the 8025, remote version, 12-36 V DC, with relays
→ For a wall-mounted version, obey the wiring instructions of chap. "8.7.1".
→ Before wiring the device, configure the selectors on the electronic board (see chap. "8.3").
→ Connect the flow sensor to the transmitter according to chap. "8.5".
