15. Add-ons mA output
Up to two analog outputs are available as add-ons. As soon as at least one mA output has been
activated, the symbol mA OUT appears in the submenu IN/OUT.
Select the symbol IN/OUT in the main menu and then select the
symbol mA OUT. Here you can set the following parameters:
22 mA alarm
If you activate this function, the mA output rises to 22mA whenever the
measuring inputs receive no proper signals.
Range
Select either 0-20mA or 4-20mA from the drop-down list.
Note
While 4-20mA gives slightly less resolution, it helps
identifying cable breaks.
Assignment
Select which parameter you want to read out via the mA output: measured value, temperature, flow
(volume based Dosing) or controller output (controller).
Note
If the mA output is assigned to the controller there is not 22 mA alarm alarm.
By changing the assignement back to measured value the 22 mA alarm has
to be activiated again.
Range min and max
You can zoom by defining which measured values correspond to 0/4mA and which to 20mA. With
these settings you can even invert the output, by assigning 20mA to a smaller value than 0/4mA. In
case of controller output the output is in %, so you cannot set range min and max.
