3.1.2 Flow URV Upper range value (URV)
At the analog output the
amount of the measured
value in the range 0 up to
URV is displayed linear to
the current range 4 to
20mA, at the digital output
1 to the frequency range 0
to end frequency Depending on
the nominal
width according
to 2...3m/s Depending on
the nominal
width (according
to 0.25 to
12m/s)
3.1.3 Limits Absolute values in flow
units from menu
3.1.1
3.1.3.1 Lo Alarm Limit Lower alarm limit
(the lower alarm limit must
be smaller than the upper
alarm limit) 10% of the URV
(depending on
the nominal
width according
to 0.2...0.3m/s ) Depending on
the nominal
width (according
to -13m/s to
+13m/s)
3.1.3.2 Hi Alarm Limit Upper alarm limit
(the upper alarm limit must
be greater than the lower
alarm limit) 90% of the URV
(depending on
the nominal
width according
to 1.8...2.7m/s ) Depending on
the nominal
width (according
to -13m/s to
+13m/s)
