9.14.2. monitoring the sensor input frequency
See chap. 9.10 to access the Diagnostic menu.
A malfunction in your process or the sensor may be revealed by an out-of-range input frequency.
The function allows for monitoring the sensor input frequency and configure the behaviour of the device if the
parametered ranges are exceeded.
The sensor input frequency f is used to determine the flow Q in the pipes using the formula f = KQ (the K factor
being expressed in pulses/s and the flow rate Q in l/s).
To be warned when the input frequency is out of range:
→
activate monitoring of the sensor input frequency in the function "activate", then
→
enter an input frequency range outside of which the device generates a “warning” event and displays the icons
and .
→
enter an input frequency range outside of which the device generates an “error” event and displays the icons
and ERR .

ACTIVATE: choose whether or not to activate monitoring of the sensor input frequency.
This monitoring is done by the generation of a “warning” event if the input frequency range defined in the “Warn
hi/lo” functions below is exceeded and an “error” event if the input frequency range defined in the “Err hi/lo” func-
tions below is exceeded.
FREQUENCY: read the sensor input frequency
WARN HI: enter the input frequency value above which a "warning" event is generated.
WARN LO: enter the input frequency value below which a "warning" event is generated.
ERR HI: enter the input frequency value above which an "error" event is generated.
ERR LO: enter the input frequency value below which an "error" event is generated.
