  • Page 18: Cover Locks

    Electronic housing cover locks, shown in Figure 8, are provided as standard with certain agency certifications and as part of the Custody Transfer Lock and Seal option. Transmitter Wiring for IDP10-A (4-20 mA Output Signal) The installation and wiring of your transmitter must conform to local code requirements.

  • Page 19: Accessing Transmitter Field Terminals

    NOTE Viatran recommends the use of transient/surge protection in installations prone to high levels of electrical transients and surges. Accessing Transmitter Field Terminals For access to the field terminals, thread the cover lock (if present) into the housing to clear the threaded cover and remove the cover from the field terminals compartment as shown in Figure 8.

  • Page 20: Wiring The Transmitter To A Control Loop

    Wiring the Transmitter to a Control Loop When wiring your transmitter, the supply voltage and loop load must be within specified limits. The supply voltage vs. the output load relationship is shown in Figure 10. Any combination of supply voltage and loop load resistance in the shaded area can be used. To determine the loop load resistance (transmitter output load), add the series resistance of each component in the loop, excluding the transmitter.

Plug unused conduit connection with the PG 13.5 or 1/2 NPT metal plug provided (or equivalent). To maintain specified explosion proof and dust-ignition proof protection, plug must engage a minimum of five full threads.

  • Page 22: Putting Transmitter Into Operation

    Putting Transmitter into Operation The following procedure explains how to sequence the valves in your flow measurement piping or optional bypass manifold to ensure that your transmitter is not over-ranged and that seal liquid is not lost. Refer to Figure 5 or Figure 6. NOTE Procedure assumes that Process shutoff valves are open.

  • Page 23: Transmitter Wiring For Idp10-V

    Transmitter Wiring for IDP10-V (1-5 VDC Output Signal) The field terminals on a transmitter with a 1 to 5 V dc output signal are shown in Figure 13. The transmitter is equipped with an internal ground connection within the field wiring compartment and an external ground connection at the base of the electronics housing.

  • Page 24: Four-Wire Connection

    For wiring runs with high resistance due to long lengths or other reasons, or for maximum accuracy, a four-wire connection as shown in Figure 15 can be used to provide input-output isolation. With four-wire configuration, voltage drop in the power supply loop does not affect measurement accuracy.

  • Page 25: Wiring To A Control Loop

    The setup with multiple transmitters connected to a single power supply is shown in Figure 17. 9. For installations with long runs, Viatran recommends using two twisted pair with one pair connected to the power supply terminals and one pair connected to the output terminals.

  • Page 30: Bench Calibration Setup

    Bench Calibration Setup The bench calibration setup requires disconnecting the process piping. For calibration setup with- out disconnecting the process piping, refer to the “Field Calibration Setup” procedure. The input setup is shown in Figure 20. Connect the input piping to the high pressure side of the transmitter as shown.

  • Page 31: General Calibration Setup

    NOTE For vacuum applications, connect the calibrating pressure source to the low pressure side of the transmitter. Also connect electronic equipment as shown in Figure 19 . General Calibration Setup 1. Each transmitter is factory characterized over its full rated differential pressure range. One benefit of this process is that every transmitter can measure any applied differential pressure within its range limits regardless of the calibrated range.

  • Page 32: Notes For Electronic Version -A And -V

    3. Each transmitter is factory calibrated to either a specified or a default calibrated range. This calibration optimizes the accuracy of the internal digital value of differential pressure over that range. If no range is specified, the default range is zero to the sensor upper range limit (URL).
  • Page 33 3. LCD Indicator The display can show any measured differential pressure in selected units regardless of the calibrated range and the values of LRV and URV (within the limits of the transmitter and display). The display can also be 0 to 100 percent. If the measured differential pressure is outside the range established by the LRV and URV values in the database, the display shows the measurement but also continually blinks to indicate that the measurement is out of range.

  • Page 34: Calibration And Configuration Using The Local Display

    When zeroing the transmitter, the internal digital value of the differential pressure is trimmed to be equal to zero and the mA output (VDC for IDP10-V) set to an appropriate value such that the mA output (VDC for IDP10-V) is a nominal 4 mA (1 VDC for IDP10-V) when the LRV pressure is applied later.
