    • If instead of a single one, 2 or 3 (maximum) feed syrups having different syrup purities are to be fed to the same batch strike the device must be informed on the execution of the change. One way to do it is to use a digital input (DIN3).
    • In this case information on purity and pan level may come in the form of 4-20 mA current from a PLC or DCS. If there are no level data available, the SeedMaster 2 will use typical simulated level data in the 35-80 % range. Operation of the DIN3 digita...

    • Change feed syrup purity
    • If instead of a single one, 2 or 3 (maximum) feed syrups having different syrup purities are to be fed to the same batch strike the device must be informed on the execution of the change. This can be done by:
    • Selecting MANUAL OPERATIONS from the MENU followed by CHANGE FSYRUP and CHANGE. The operation will step the feed syrup number to the next one (from 1 to 2, then to the maximum 3). (For more information on feed syrup changes see: 3.6.3).
    • If a level transmitter is connected to the SeedMaster 2, using SETUP -> INPUTS -> FEED SYR. PUR up to 3 different purities and 2 level threshold data (where the change of purity should be made) can be selected from the keyboard to implement automatic ...
    • If a level transmitter is connected to the SeedMaster 2 up to 3 different purities and 2 level thresholds can be sent via COMMUNICATION to implement automatic change of feed syrup purity.
    • Finally, level, purity and level threshold data can all be sent via COMMUNICATION to implement automatic change of feed syrup purity.
