7.4.10 connecting the flow sensor to the transmitter
Before connecting the flow sensor to the transmitter 8025 UNIVERSAL:
• set selector "SENSOR TYPE" depending on the output signal providing from the flow sensor. See
“Figure 25” and “Table 1”, page 30.
• if the selector "SENSOR TYPE" is set on "NPN/PNP", set the selector "SENSOR SUPPLY" depending
on the transmitter supply voltage. See “Figure 26”.
• set selector "LOAD" depending on the type of signal sent out by the flow sensor and on the load
wanted on terminal 1 "PULSE INPUT" of terminal block "FLOW SENSOR". See “Table 1”, page 30.
Selector D makes it possible to configure the type of signal the 8025 Universal receives from the flow sensor.
→
Set the selector on the right (default position) when
the signal from the flow sensor which is connected to
the 8025 Universal is either:
• a pulse signal, NPN or PNP
• an "on/off" signal (Reed relay for example)
• a 0-5 V DC standard voltage signal (TTL, for example)
→
Set the selector on the left when the
signal from the flow sensor which is
connected to the 8025 Universal is a
sine-wave signal (coil).

When selector "SENSOR TYPE"
above is set on "NPN/PNP",
selector B makes it possible to
configure the supply voltage for the
flow sensor.

If the 8025 Universal is energized with a 115/230 V AC power supply,
set selector "SENSOR SUPPLY" on "L+" (default position).
→
If the 8025 Universal is energized with a 12-36 V DC power supply,
set the voltage selector "SENSOR SUPPLY" depending on the voltage
needed by the remote flow sensor: "+5V", "L+" (default position) or
"(L+)-12V".
