Instruction SI 1-02689 April 2020 Replacing a Legacy Foxboro IMT25/IMT96 Paired with a Legacy Magnetic Flowtube with an IMT33A/IMT31A Using the R0101ZS Cable This procedure describes how to replace the Schneider Electric IMT25 or IMT96 products paired with a Legacy Magnetic Flowtube with an IMT33A or IMT31A. You must use the R0101ZS cable specified in this document when installing the new transmitter. HAZARD OF ELECTRIC SHOCK ! DANGER Follow all wiring instructions provided in this document carefully. Failure to follow these instructions will result in death or serious injury. Reference Documents Document MI 021-120 MI 021-380 MI 021-381 MI 021-386 MI 021-387 MI 021-402 Table 1.

DANGER Do not install an IMT33A or IMT31A to a Legacy Magnetic Flowtube in a hazardous environment. Failure to follow these instructions will result in death or serious injury. NOTICE INCORRECT MARKINGS ON DATA PLATE All previous flowtube electrical certifications are no longer valid when the flowtubes are connected to an IMT33A or IMT31A. All electrical certifications must be removed from the existing flowtube's data plate as they are no longer valid. Failure to follow these instructions can result in incorrect markings on the flowtube's data plate. NOTE For this procedure to work properly, you must have a nominal known flowrate. The nominal known flowrate in the line can be determined by observing the flowrate on another meter in the line, collecting the data from a historian and replicating those conditions, calculating the flowrate based on a pump curve, or observing the change in volume in a tank over time and calculating the flow rate. Electric equipment should be installed, operated, services and maintained only by qualified personnel. No responsibility is assumed by Schneider Electric for any consequences arising out of the use of this material. 1. Locate the transmitter to be replaced by an IMT33A/IMT31A. 2. Install the new IMT33A/IMT31A. Select the instructions to be used from the following table: To replace an IMT25 or IMT96 paired with a: 9300A/8000A 2800/8300 9300A/8000A 2800/8300 With an: Follow the instructions provided in: IMT31A IMT31A IMT33A IMT33A "Replacing the IMT25/IMT96 with an IMT31A (Using a 9300A/8000A Series Flowtube)" on page 4. "Replacing the IMT25/IMT96 with an IMT31A (Using a 2800/8300 Series Flowtube)" on page 6. "Replacing the IMT25/IMT96 with an IMT33A (Using a 9300A/8000A Series Flowtube)" on page 8. "Replacing the IMT25/IMT96 with an IMT33A (Using a 2800/8300 Series Flowtube)" on page 10. 3. Configure the required parameters in the new IMT33A/IMT31A. Note that the URV must be configured prior to Step 4. 2 SI 1-02689 � April 2020 4. Configure the following parameters based on the transmitter used: Replacement Transmitter: IMT33A IMT31A Parameter Name GK GKL Parameter Value 5.00 10.00 5. Verify that the IMT33A/IMT31A is reporting a value below 100% of the transmitter's URV. a. If the value reported is equal to 100% URV, reduce the GK/GKL value by half (for example, if GK was set to 5, reduce it to 2.5). b. Repeat Step 5a until the reported value is below 100% of the transmitter's URV. 6. Record the indicated flow rate. 7. Determine the new GK/GKL using the following equation: FR1 = GK1 = GKL1= FR2 = Flowrate from Step 6. GK value from Steps 4/5. GKL value from Steps 4/5. Known Flowrate. Example: For GK: FR1 = (Indicated Flowrate) GK1 = (GK Value From Table) FR2 = (Known Flowrate) 1000 GPM 5 1057 GPM GK = 1057 * (5/1000) GK = 1057 * (.005) GK = 5.285 Example: For GKL: FR1 = (Indicated Flowrate) 26 GPM GKL1 = (GKL Value From Table) 10 FR2 = (Known Flowrate) 16.32 GPM GKL = 16.32 * (10/26) GKL = 16.32 * (.38462) GKL = 6.277 3 SI 1-02689 � April 2020 8. Configure the new GK value in the IMT33A or the GKL value in the IMT31A based on the value determined in Step 7. 9. Verify that the indicated flow rate is equal to the expected flow rate.
