Getting acquainted with the flow computer wiring:
Back terminal wiring:
The back terminal wiring indicates the overall positions of the terminal plugs and their functions. Though
the back panel’s jumpers are also shown, refer to the next drawing, “Back Panel Jumpers”, for information
on their settings and functions.
The Smart Flow Computer receives its power via the two topmost pins on Terminal P1, on the left of the
terminal board. Also on Terminal P1 are, from top to bottom, inputs from the two turbines and the RS-485
serial connection.
To the right (P4), from top to bottom, are status input 1, density frequency input, and switch output 1 and 2.
Terminal P3, at the lower bottom, handles analog inputs and outputs. These are, in order from right to left,
analog inputs 1-4 and analog outputs 1 and 2.
Terminal P5, top middle, is the RTD terminal block, "100 platinum RTD input".

Back Panel Jumper
In this illustration, a jumper is “ON” when the jumper block is used to connect the jumper’s to wire prongs.
“OFF” means the jumper block is completely removed or attached to only one of the two wire prongs.
Note: R11 and R3 could have a vertical orientation instead of a horizontal
orientation on certain Smart Flow Computer models.

INPUT/OUTPUT: Assigning and Ranging Inputs
Input/Output Assignment
We will now configure your SFC332L Flow Computer’s inputs and outputs. The flow computer allows the
user to configure the inputs and outputs. (I.e. Analog #1 is pressure for Meter #1). The flow computer will
not use the unassigned inputs.
How to assign a transmitter to an I/O point
1Click “Configure Device”, configuration menu is prompted
2On configuration menu, click “Input Assignment”
3Enter assignments for DP, temperature, pressure, density and spare inputs.
4Assignment (1-n). Assignments 1-4 are analog inputs attached
to terminal of the back panel. These inputs accept 4-20mA or 1-5
volts input and are suitable for temperature, pressure, density, or spare inputs. An assignment
5 is strictly RTD (temperature) input only for the meter, densitometer or spare. Assignment 7
indicates a density frequency input; it is assigned automatically once you choose live density
frequency input in the setup menu at density type Assignment 10 (module 1) is for
Rosemount multi-variable module only. DP, pressure, and temperature for the meter can be
assigned. When a frequency type primary element is hooked to the flow computer, the Multi
Variable pressure and temperature can be used and the DP becomes a spare input that could
be assigned for strainer differential.

Ranging the Transmitter Inputs:
1. Enter the range values: after assigning the inputs scroll down the transducer inputs
assignment menu to scale the 4-20mA. Enter the value at @4mA and @20mA. Enter both
values similar to the way the transmitter is ranged. 1-5 volts is equivalent to 4-20mA. Enter
the 1 volt value at the 4mA, and 5 volt value at 20mA. When the Multi Variable is used the 4-
20 ma scale has no effect on anything and does not need to be configured for that input. The
reason is simply that the flow computer gets the data via digital communication from the
transmitter in engineering units, and therefore a scale is not needed. Normal pressure range is
0-3626, temperature –40 to 1200, DP –250 to 250, or -830 to 830 inches of water.
2. Enter the high and low limits: high limits and low limits are simply the alarm points in
which you would like the flow computer to flag as an alarm condition. Enter these values
with respect to the upper and lower range conditions. Try to avoid creating alarm log when
conditions are normal. For example: If the line condition for the pressure is between 0 to 500
PSIG, then you should program less than zero for low pressure alarm, and 500 or more for
high pressure alarm. High limits are also used in the SCALE for the Modbus variables. The
high limit is equalent to 32767 or 4095. The low limit is not used for calculating the scale.
The scale starts at zero to wherever the high limit value.
3. Set up the fail code: Maintenance and Failure Code values tell the flow computer
to use a default value in the event the transmitter fails. The default value is stored in
Maintenance. There are three outcomes: the transmitter value is always used, no matter
what (Failure Code = 0); the Maintenance value is always used, no matter what
(Failure Code = 1); and the Maintenance value is used only when the transmitter’s
value indicates that the transmitter has temporarily failed (Failure Code = 2).
RTD inputs will skip 4-20 mA assignment because RTD is a raw signal of 50(ohms) to 156. Readings
beyond that range require a 4-20 mA signal to the flow computer or using the built in Rosemount Multi
Variable transmitter. The Rosemount Multivariable has a range of –40-1200 degrees Fahrenheit.
Density coefficients for raw frequency inputs are programmed in this menu. The menu will only show
parameters relevant to the live density selected (i.e., Solartron or UGC, etc.).
