Setting The Bi-Directional Auto 2 Range - Fuji Electric FLR-3 Instruction Manual

4.10.3. Setting the Bi-directional auto 2 range

Description
 The function measures the flow rate of either forward
or reverse flow while changing over the range
corresponding to the flow direction.
 The current output changes with the action range as
illustrated on the right.
 The hysteresis can be set to between 0 and 20% of
either range of FULL SCALE1 or FULL SCALE2 and
FULL SCALE3 or FULL SCALE4 whichever the span
is smaller.
 Upon setting DO1 and/or DO2 to "FULL SCALE2", a
contact outputs "FULL SCALE2" action.
Select "ACTIVE ON" or "ACTIVE OFF" separately.
(See 4.10.5.)
 Settable range: ±0.3 to 10[m/s] in terms of flow velocity in piping for any of FULL SCALE1 and FULL SCALE2.
When FULL SCALE1 and FULL SCALE2 are set, FULL SCALE3 and FULL SCALE4 are automatically set.
FULL SCALE1 and FULL SCALE3, FULL SCALE2 and FULL SCALE4 are related as follows.
|FULL SCALE1 | = |FULL SCALE3|
|FULL SCALE2| = |FULL SCALE4|
* Preset PIPE PARAMETER and FLOW UNIT.
* If a value beyond the settable range is inputted, "INPUT ERROR" appears and then last setting is resumed.
* If "FLOW UNIT" has been changed after setting the range, redo the range setting.
* When FULL SCALE2 is not used (in the case of single range), set "0" to FULL SCALE2.
<Note> The flow rate unit is as selected by "FLOW UNIT" in "MEASURE SETUP" mode. Before setting range, set the "FLOW UNIT".
(See 4.8.2.)
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) Set "RANGE HYS." to 7%.
* Preset "PIPE PARAMETER" and "FLOW UNIT".
