    Note - Ranges and input types, the use of relays as alarms and alarm points are, among others, items which the user can program through the MCY-20 Configuration Module (if desired, specify such information so the whole programming may be previously done by PRESYS). Note: Any other software or hardware characteristic desired may be available upon request.

    Instruments TY - 2090 2.6 Communication The TY-2090 Transmitter can communicate with computers via RS-232 or RS- 422/485 provided the optional communication module is installed and the proper communication parameters are configured via software. Specific information about communication and signal connection can be found in the Communication Manual.

  • Page 17: Configuration

    PRESYS Instruments TY - 2090 When the MCY-20 Configuration Module is connected to the Transmitter under normal operation, the instrument begins to function as a transmitter and as a process monitor as well, through the Module display. Under configuration time operation mode the user, through the MCY-20 Configuration Module, selects and assigns values to the parameters which regulate the Transmitter functioning, when in normal operation.

    Instruments TY - 2090 4.4 - Calibration The TY-2090 Transmitter is accurately calibrated in factory and does not require regular calibration under normal conditions. If, for any reason, a recalibration is required, follow the procedure described below. Disconnect process signals from the Transmitter I/O terminals.
  • Page 36 PRESYS Instruments TY - 2090 After running through all references of the table related to the input type to be calibrated, the calibration process will have been completed.
