As soon as the mA outputs have been activated, the symbol mA OUT appears in the submenu IN/OUT.
Here you can set the following parameters: Main menu > IN/OUT > mA OUT > choose an output > set parameters
- Assignment - Select which parameter you want to read out via the mA output: pH, DIS 1, optionally ORP, conductivity, DIS 2, or control variables
- Range - Select either 0-20 mA or 4-20 mA from the drop-down list. While 4-20 mA gives slightly less resolution, it helps identifying cable breaks
Note: Upon startup, the mA outputs are set to “not used” since they are equipped with a load monitor. If you assign a parameter to a mA output while the output is disconnected or the connection is interrupted somewhere, the event message “load impedance mA” appears in the display
- 22 mA alarm - If you activate this function, the mA output rises to 22 mA during an active alarm.
- Range min and max - You can zoom by defining which measured values correspond to 0/4 mA and which to 20 mA. With these settings you can even invert the output, by assigning 20 mA to a smaller value than 0/4 mA. In case of controller output, the output is in %, so you cannot set range min and max
Note: If the output is assigned to control, the 22 mA alarm is deactivated. It needs to be reactivated if the output is reassigned to measurement.
