Operation
Figure 29 Example for programming 4-20 mA output, register, for pH measuring channel.
4 mA = pH 7. Pump does not work.
20 mA = pH 5. Pump dispensing at maximum.
Important notes:
• During cleaning and the time of post-cleaning the 4-20 mA output (control) does not
change.
• During programming and calibration of the corresponding channel, the 4-20 mA
output (control) automatically fixes at 3 mA.
• If a control with 2 limits is selected through the 4-20 mA output, one output can be
selected for register and the other one for control.
