Please be aware of the following information while assembling the meter assembly. Refer to Table A-11 on page A-23 for part references.

  • Page 89: Overview

    Characterization ....... . . page 6-12 OVERVIEW This section describes how the Rosemount Smart Retrofit Kit can be used to retrofit a Rosemount 1151AP, DP, GP, HP, or LT transmitter with 4-20 mA dc linear or square root output.

  • Page 90: Retrofitting Overview

    Use proper earth grounding techniques when handling the smart electronics assembly. The smart electronics assembly is potentially sensitive to electric static discharge. Confirm the output code of the Rosemount 1151 is analog (4-20 mA). It will have an “E” in the eighth character in the model number on the transmitter nameplate.

  • Page 93 Reference Manual 00809-0100-4360, Rev BA Rosemount 1151 August 2008 4. Pull the amplifier board (2) or amplifier/squaring assembly (13) directly off the bayonet connectors (6).
  • Page 94 Reference Manual 00809-0100-4360, Rev BA Rosemount 1151 August 2008 5. Pull the header board assembly (3) off the bayonet connectors. The header board must be reinserted. Do not cut the wires (9) or remove the header board. 6. If the transmitter has linear output electronics, remove the three standoffs (4).
  • Page 95 Reference Manual 00809-0100-4360, Rev BA Rosemount 1151 August 2008 7. Align the zero and span adjust screws (10) so that the potentiometer blades are perpendicular to the board.
  • Page 96 Reference Manual 00809-0100-4360, Rev BA Rosemount 1151 August 2008 8. For linear output models, grip the calibration board (5) by the interface pin. (Removing the calibration board disables the conventional zero and span screws.)
  • Page 97 Reference Manual 00809-0100-4360, Rev BA Rosemount 1151 August 2008 Insert the standoffs (7), if necessary. The transmitter is now ready to receive the plug-in smart electronics assembly.

  • Page 98: Installing The Smart Retrofit Kit

    Reference Manual 00809-0100-4360, Rev BA Rosemount 1151 August 2008 INSTALLING THE Installing the smart retrofit electronics kit in the transmitter requires installing plastic spacers to accommodate the retrofit kit and securing the retrofit SMART RETROFIT KIT electronics. After the retrofit kit has been installed, it is necessary to attach eyelets to the terminal side of the transmitter.
  • Page 99 Reference Manual 00809-0100-4360, Rev BA Rosemount 1151 August 2008 2. Align the header board with the bayonet connector pins, and slide the header board halfway down the pins. 3. Align the tops of both spacers with the bayonet connector pins, and slide them down the pins, pushing firmly on both the spacers and the header board to seat the board.

  • Page 100: Characterization

    The microprocessor uses these values to make linearization corrections. The digital-to-analog converter then converts the corrected digital signal into a 4–20 mA dc output. The Rosemount 1151 Transmitter will stay in high alarm (approximately 22 mA output) until the characterization sequence is completed.

  • Page 101: Before Characterizing The Transmitter

    Pressure units on your pressure source? • Serial number on the transmitter S/N tag? 2. Connect the pressure source. 3. Remove the terminal side cover of the Rosemount 1151 Pressure Transmitter. 4. Connect power supply leads to the terminal block. Apply power to the transmitter.
