Bi-Directional Auto 2 Range - Fuji Electric FSJ Instruction Manual

Bi-directional auto 2 range

Description
● This function is used to measure both the forward and
reverse flow rates based on flow rate and flow
direction while changing the range.
● Current output changes based on the working range
as shown in the diagram on the right.
● Current is output for either the volume flow rate or
mass flow rate set with the analog output source
designation (see section 4.8.1.3).
● Hysteresis can be set in the 0 to 20% range for the
smaller of the span for full scale 1 and full scale 2, or
full scale 3 and full scale 4.
● By setting DO1 or DO2 to "FULL SCALE 2", contact
output is activated when "FLOW RATE FS2" is
activated.
Set "ACTIVE ON" or "ACTIVE OFF" separately. (See Section 4.9.5)
● Setting range:
Both VOLUME FLOW FS1 and VOLUME FLOW FS2 are in the ±0.3 to 50 [m/s] range based on the flow velocity calculated inside the
pipe.
Both MASS FLOW FS1 and MASS FLOW FS2 are ±99999999.
By setting FLOW FS1 and FLOW FS2, FLOW FS3 and FLOW FS4 are set automatically.
The relationship between FLOW FS1 and FLOW FS3, and FLOW FS2 and FLOW FS4 is shown below.
|FULL SCALE 1｜＝|FULL SCALE 3｜
|FULL SCALE 2｜＝|FULL SCALE 4｜
* It is necessary to set the piping parameters, as well as the VOLUME FLOW UNIT and MASS FLOW UNIT beforehand.
* If a setting value that exceeds the setting range is entered, "INPUT ERROR" is displayed, and the value returns to the original
setting value.
* If "FLOW RATE UNIT" is changed after setting the range, set the range again.
* If not using FLOW RATE FS2 (if single range), set FLOW RATE FS2 to "0".
(Note 1) The flow rate unit is the unit selected at "VOLUME FLOW UNIT" and "MASS FLOW UNIT". Specify the "FLOW RATE UNIT"
setting before setting the range. (See section 4.7.2) (See section 4.7.4)
For actual keying, refer to the typical operation indicated below. Set the protection to OFF beforehand. (See Section 4.4.1.)
Operation Set "BI-DIR AUTO 2" to "RANGE TYPE", 10[m
(example) FS2".
Set "RANGE HYS." to 7%.
* Set the PIPE PARAMETER and VOLUME FLOW UNIT beforehand.
