Reed-switch
The F030-P is suitable for use with flowmeters which have a reed-switch. To avoid pulse bounce
from the reed-switch, it is advised to select REED LP - low-pass filter (read chapter 3.3.2).

NAMUR-signal
The F030-P is suitable for flowmeters with a NAMUR signal. The standard F030-P is not able to
power the NAMUR sensor, as an external power supply for the sensor is required. However, a 8.2V
sensor supply voltage (terminal 6) can be provided with type PD.

4.6.2 TERMINAL 4-5: POWER SUPPLY - TYPE PX (DEFAULT) AND PD (OPTION)
To power the F030-P an internal battery can be used (type PB) and / or an external DC power
supply of 8-30V DC (type PX) or 16-30V DC (type PD).
Connect the "
- " to terminal 4 and the " + " to terminal 5.
When power is applied to these terminals, the optional internal battery will be disabled / enabled
automatically to extend the battery life time.
4.6.3 TERMINAL 6: POWER SUPPLY TYPE PD: 8.2V SENSOR SUPPLY
With this option, a limited power supply for the sensor is available, for example to power a Namur
sensor. It offers 8.2V DC (max. 5mA).
This terminal is only available if type PD has been ordered
