3.1.13 NL Frequency input 1
Figure 92: Menu NL Frequency input 1
Frequency input 1 is shown here as an example for all frequency inputs. These men-
us are essentially display menus. Coordinate
NL01 Frequency 1
shows the input
frequency, which is assigned to operating value measuring channel 1 in this case
(see coordinate
NL15 Beneficiary
).
With use of the Ex board, input
NL10 Weighting
is free and can be used for other
counter inputs. The assessment and the unit must be entered here appropriately.
The ERZ2000-NG has 4 pulse / frequency inputs. Usually frequency 1 and 2 are
used for a turbine, but often (e.g. in case of Ultrasonic meter) they are unused. They
may than be used for example for another flow rate meter. In NL10 (pulse weight),
NL11 (unit) and NL12 (name of the unit) a correct counting has to be adjusted. The
quantities are accumulated on NL08 and NL09 and are archived in group 16 (extra
inputs).
