Reed-switch:
The F130-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).

NAMUR-signal:
The F130-P is suitable for flowmeters with an Namur signal. The standard F130-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 11) can be provided with power supply type PD, PF, PM.

4.6.5 TERMINAL 12-13: EXTERNAL START
With this function, the batch controller can be started with an external switch. The input must be
switched with a potential free contact to the GND-terminal number 12 for at least 0.3 seconds.
