Bi-Directional Range - Fuji Electric FSJ Instruction Manual

Bi-directional range

Description
● This function is used to measure both the forward and reverse flow rates based on
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% working range.
● 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.
* 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> 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" to "RANGE TYPE", 20[m
(example) Set "RANGE HYS." to 7%.
* Set the PIPE PARAMETER and VOLUME FLOW UNIT beforehand.
