CONFIGURING FLOW PROCESSOR OUTPUTS AND
INPUTS
Frequency Outputs (1 and 2)
Figure 23: Frequency out tab
The Frequency Out table is used for configuring both of the EC80 Flow Processor’s
frequency outputs. All EC80 Flow Processors come with 2 frequency channels,
and the channels can be configured independently. Use this table to completely
configure the type of information to be output for each channel, and adjust the
output scaling. A few possible types are volumetric flow rates, mass flow rates,
temperature (both ° F and ° C), the sum of rotor frequencies (Rotor A + Rotor B),
pressure and differential pressure.
1. Click the down arrow to select the engineering unit. The engineering units for
Frequency 1 and frequency 2 do not need to be the same.
2. Fill the tables according to instructions in “Table Data Entry” on page25. The
rst entry typically corresponds to zero ow and is set to zero Hertz, while
the last entry is typically maximum ow. The maximum output frequency is
sixteen Hertz.
OTE:N Setting the maximum flow rate to a frequency greater than 16 kHz causes
the flow processor to output 16 kHz.
Click the summation check box to enable totalizing (accumulation) of the
frequency output. This feature is only applicable to special firmware editions.
The feature needs to be configured at the factory and is not available in standard
applications. The feature works by summing flow rates and outputting a frequency
proportional to total flow, not flow rate.
The test frequency button takes the value input as the scaling frequency and
outputs that frequency from the flow processor. Use this feature to verify that
the flow processor is outputting the appropriate frequency and to verify the
calibration of the flow processor.
