FX-300-ISE Module Function and Programming List of Parameters
If the software lock (parameter. no.1) is “on” the parameter can only be read. Set software lock
P01 to “off” to change values.
Par. no.2
sets the module’s address for Modbus communication.
Par. no.3
indicates the type of sensor for the temperature input.
Par. no.4
If Par no.7 is set to ISE, the signal is temperature compensated. Par. no.4 sets
the temperature compensation to either set (manual) or based on the
measured temperature.
Par. no.5
sets the temperature for when temperature compensation of the pH is in fixed (manual)
mode.
Par. no.6
If a long cable is used for the Pt100 sensor the cable impedance should be entered
and compensated for this offset.
Par. no.7
selects the output to be either ISE or temperature.
Par. no.8
sets the analog output to either 0-20mA or 4-20mA.
Par. no.9
sets the analog output scaling to either low (0.00-9.99ppm), mid (00.0-99.9ppm) or
high (000-999ppm) range.
Par. no.10
are used to set the ppm value that corresponds to 0/4mA output setpoint
and no.11
(
Par. no.10
) and sets the ppm value that corresponds to 20mA output setpoint (
Par
no.11
). The difference between Par. no.10 and 11 must be at least 20% of the working
output range selected (either low, mid or hgh range). The display and output ranges
are altogether decoupled.
Par no.12
Variable to define the mV change for each “Up” or “Down” button depression when
calibration is performed.
Par. no.13
Displays formula weight of measured ion (next page details how to determine which ion
correspond to this value)
Par. no.14
View and edit the working (effective) sensor offset
Par. no.15
View and edit the working (effective) sensor slope
Par. no.16
Offset adjustment for low 0/4mA analog output trim.
Par. no.17
Gain adjustment for 20mA high analog output trim.
Par. no.18
If no keys are pressed for 10 min the display will show flashing bar (Energy Save).Press
any key to return.
Par. no.19
The Modbus standard requires a baudrate of 9,600 or 19,200 set in accordance with
the Modbus-master.
Par no.20
Feature to reset the analyzer back to factory default.
NOTE
: To exit setup mode, press the ‘down’ button until parameter P00 is displayed, then press
‘mode’ until PPM (run) mode indicator lights.
