AZURA® Valve Unifier VU 4.1 Instructions V6855
Binary control
If the valve drive was set to binary operation (see “Input” on p. 26), then the
connections BIN 0 - BIN 3 are available as inputs.
Binary code
A binary code is entered during binary control so that the valve can be set
externally in the correct position (nominal position).
