mA output settings
Configure the settings of mA output.
n
mA1/mA2/mA3 (Ad)/mA4 (Ad)
Set each mA output. “Output” is default.
Output:
mA output according to each setting
Simulate
output fixed mA set by output span (%)
Off
No mA is output. 4 mA is fixed output.
When mA Output/Input is “-A2”, mA output of only mA1 and mA2 are settable. When mA Output/
Input is “-N4”, mA output of mA1, mA2, mA3(Ad), mA4(Ad) are settable. When mA Output/Input
is “-N2”, setting mA3(Ad)/mA4(Ad) does not affect the operation.
4.3.1
Output
Current value is output according to each setting. When you use auto-range switch or 3-range
switch, always set mA1 to the parameter whose range you want to change.
l
Process parameter slot
FLXA402T allows multiple sensor connection, according to specification you choose.
Select a process parameter sensor from “Sensor 1-1”, “Sensor 2-1”, “Sensor 2-2”, “Converter” to
output. Don’t select “Sensor 2-2”.
When you set converter parameter (mA input) to the process parameter, select “Converter.” But
you cannot set the converter parameter to mA1.
Sensors must be assigned addresses for MODBUS network in advance. Read 4.6.1.
l
Process parameter
Set process parameter to output according to sensors. If the setting is not configured properly, a
setting error occurs. Select parameter as follows.
forTB:
Turbidity
for FC
Residual chlorine, temperature
for PH
pH, temperature
for SC
Conductivity, temperature
for Converter: AI,
Note that only turbidity and residual chlorine can be selected for mA1.
l
output line form
The output method:
Linear or Line chart (select one)
Linear:
Set 0% value and 100% values.
Line chart:
You can output in three-point line segment by setting up the values of mA output
and process value by percentage between 0% to 100%.
Be sure to set the segmental changeover point value between the 0% value and the 100% value.
Even if the output format is “linear” at a converter setup, errors will occur if the changeover point
value falls outside the range.
When switch range is not used, use the parameter of Range 1
l
Burn
Select one mA from
“Off”, “Low” or “High” to output the failure. Read
4.8 Error settings for setting
failures.
Off:
Output by the measured value.
