    Modifications of positioner firmware

    Modifications of positioner firmware in comparison to previous versions

    Previous New

    1.00 1.10

    The serial interface and serial interface adapter allow the positioner to be operated and configured using TROVIS-VIEW software

    The following additional status messages were implemented: Code 76 - No emergency mode Code 77 - Program loading error Displays number of zero calibrations performed since the last initialization.

    For initialization of "AIR TO CLOSE" actuators, the direction of action (Code 7) is auto- matically set to increasing/decreasing.

    Code 3, the activation period of the enabled configuration function was extended to 120 s.

    1.10 1.20

    Electronics changed, no new functions added.

    1.20 1.30

    New EXPERTplus diagnostics functions (Code 48) added Positioner in EXPERTplus version with extended diagnostics features.

    A running initialization can be canceled by pressing the rotary pushbutton.

    The position transmitter (Code 37) and solenoid valve (Code 45) options are automati- cally recognized.
