4.6.8 TERMINAL 17-18: ISOLATED PULSE INPUT – TYPE IG
The F103-P is suitable for use with an active flowmeter by connecting it to the isolated pulse input
on terminals 17 and 18. The maximum frequency of the isolated pulse input is 3.5kHz and the active
signal must switch between 0V and 3V ~ 30V to detect a pulse. The maximum current taken up by
the input circuitry is 6mA.

To connect a passive flowmeter signal, please see Terminal 09-11: Flowmeter input.
4.6.9 TERMINAL 19-20: ISOLATED RESET INPUT – TYPE IG
With this function the total can be reset to zero with an external active signal. The Total resets only
when the voltage rises from 0V to a value above 3V.
The input must be activated with an active signal of 3-30V between terminals 19 and 20 and must
remain active for at least 3 seconds to perform the reset. Afterwards, the input signal must remain at
0V for 3 seconds before a new clear action can be performed. The maximum current taken up by the
input circuitry is 6mA.

To connect a switch or passive signal to perform the reset function, please see Terminal 12-13:
External reset – Type IB.
