Before connecting the flow sensor to the dosing controller 8025 Batch, in a panel-mounted or a wall-
mounted version:
• Set selector "SENSOR TYPE" depending on the output signal originating from the flow sensor. See
“Figure 29” and “Table 5”, page 40.
• If selector "SENSOR TYPE" is set on "NPN/PNP", set selector "SENSOR SUPPLY" depending on the
dosing controller supply voltage. See “Figure 30” and “Table 5”, page 40.
• 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 5”, page 40.
Selector C makes it possible to configure the type of signal the 8025 Batch, panel- or wall-mounted version,
receives from the remote flow sensor.
→
Set the selector on the right (default position) when
the signal from the flow sensor which is connected to
the 8025 Batch 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 Batch is a sine-
wave signal (coil).

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

If the device is energized with a 115/230 V AC power supply, set
selector "SENSOR SUPPLY" on "L+" (default position).

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