Procedure
1. Disable the Write Protect switch in the CPU Module to write any of the following
configuration parameters to your meter.
2. Click the Setup Units tab to configure the system units (U.S. Customary or Metric
units), Volume units, Flow rate time units, Velocity units, Pressure units and
Temperature units. Click
Apply to write the parameters to the meter.
3. Click the
Setup Outputs
tab to configure the Device Variables Mapping, Units,
Frequency/Digital outputs, Frequency and Digital Outputs 1 and 2, Analog outputs,
Digital Input, Pressure and Temperature.
a. Analog output 1 (HART) - Content (Primary Variable) displays Uncorrected
Flow Rate and is a read only attribute). Configure Direction (flow), Lower
Range value, Upper range value and Alarm Action and view the HART
Parameters Tag, Date, Descriptor, Message, Final Assembly Number Poll
Address, Number of Response Preambles.
b. Analog Output 2 - Content (Secondary Variable) displays Uncorrected Flow
Rate and has a read only attribute. Configure Direction (flow), Lower Range
value, Upper range value and Alarm Action. Map the Third and Four variables
using the Manual Setup wizard. Selections include Uncorrected Volume Flow
Rate, Pressure and Temperature.
4. After all of the data shown below is entered, click Apply to write the parameters to
the meter.
a) Click the Frequency/Digital Outputs tab to configure Frequency/Digital
Output 1, 2 and 3 Source and drive Mode. Select the Source for each
Frequency/Digital output and select the desired drive Mode. The Mode
options are Open Collector which requires an external excitation voltage and
pull-up resistor or TTL mode which outputs a 0-5 VDC signal (each Frequency
output has an A and B output phase).
Note
If changes are made to any Source variable on this page, apply the changes
and navigate to the
Guided Setup page. Navigate back to the Manual Setup
for the changes to be reflected in other Manual Setup pages.
b) Click the
Frequency and Digital Output 1
tab to configure the Content,
(flow) Direction, Channel B Phase frequency output, Lag forward, Lead
Reverse or Lead Forward, Lag Reverse (Phase B lags Phase A while reporting
forward flow and lead Phase A while reporting reverse flow or the opposite),
Digital Output 1 Channel A Content and Polarity, Channel B Content and
Polarity, Maximum Frequency, and Lower and Upper Range Units of Measure.
c) Click the Frequency and Digital Output 2 tab and repeat Step 3 to configure
Frequency and Digital Output 2 parameters.
5. Click Setup HART to configure the HART parameters (tag, date, descriptor,
message text, Final Assembly number, Poll address and number of response
preambles are displayed). After all of the data is entered click
Apply to write the
parameters to the meter.
