KHD on PL3.1

[John1964]

I have a KHD set, Doser 2.1 SA is the controller (master) for the KHD, during measuring (adding the reagent with pump) you hear a buzzing sound from time to time and the pump slowly adds the reagent, everything is fine in other words.

I also have a PL 3.1 N ex with the latest software running ( V1.1.1.7 ) i tried running the KHD with the Doser 2.1 as a slave with the PL3 controlling the measuring, while measuring ( adding the reagent with pump) you hear a constant loud clicking sound from the pinch valve.

Not sure what this means i switched back to the Master Doser 2.1 SA controlling the KHD and everything is back to normal, no more clicking sounds from the KHD.

Looks like the software for PL3.1 is not yet ready yet for controlling the KHD.

Anyone else has this problem?
