ABB AX400 Series User Manual

Single and dual input analyzers for pH/Redox (ORP)
AX416, AX436, AX460, AX466 & AX468 5 Programming

5.6 Configure Outputs
Configure Output 1
Output 2 configuration (and Outputs 3 and 4 if option board fitted and analog features
enabled – see Section 7.3, page 57) is identical to Output 1 configuration.
Assign
Select the sensor and analog output required:
Sen.A
Sen.B
– pH/Redox (ORP)/mV for the selected sensor.
Temp.A
Temp.B
– Temperature for the selected sensor.
A-B – Difference between the Sensor A and Sensor B readings.
Note. Sen.B, Tem p. B and A-B are applicable only to dual input analyzers.
Range
Select the analog output current range for the selected output.
Span Value
pH (or mV or Deg.C or Deg.F or A-B) and Adjust are shown alternately on the upper
display line. Use the and keys to adjust the displayed reading to the required
span value.
Note. The minimum and maximum span values are determined by the Zero Value
setting (see next page) plus the minimum differential, e.g. to set Span Value to 0.00 pH,
first set
Zero Value to –2.00 pH.
