Open the back pressure regulator and all fluid drain valves in the system, having a waste container ready to catch drainage. [. . . ] Thread the transducer's cable (25a*) through the adapter (42*) and conduit (44*). Torque the adapter (F) first, then the nut (E) to 15-20 ft-lb (21-27 N·m). Reinstall the cover (32*) with two screws (12*). 7 Torque to 15-20 ft-lb (21-27 N·m). 7 *43 *44 58* 7 *42 25a* *41 D FIG. Pressure Transducer ti8721a Pressure Sensor Calibration Information Pressure sensor information (Pr 20. 34, 20. 35, and 20. 36) for your system must be keyed into the Variable Frequency Drive before system start-up. To prevent accidental change of pressure sensor calibration parameters, they are locked by Pr 20. 16. Set Pr 20. 16 to 0 to lock pressure sensor parameters. c.

FIG. Circuit Board Connections 4 311603C Pressure Transducer Calibration Procedure Pressure Transducer Calibration Procedure E-Flo pressure sensor must be calibrated against an instrument grade High Precision Pressure Transducer, which should be installed near the E-Flo pressure sensor. Ensure that the High Precision Pressure Transducer calibration is up to date. Use Keypad to navigate to Pr 20. 33; monitor its reading for 5 ­ 10 seconds to determine its average value. Navigate to Pr 20. 34 and enter the recorded average value of Pr 20. 33. Keep the system pressurized and ensure that pressure does not fluctuate. Take a pressure reading from the calibration instrument and make a record of it. d. Navigate to Pr 20. 33; monitor its reading for 5-10 seconds to determine its average value. Navigate to Pr 20. 31 and verify that its reading is within the range of 0-3 psi. Verify that reading of Pr 20. 31 is within +/- 2. 5 psi of the system pressure. c. 4. If system is rated to a pressure lower then 250 psi, use maximum allowable rated pressure. Verify that reading of Pr 20. 31 is within +/- 2. 5 psi of the system pressure. 311603C 5 Graco Standard Warranty Graco warrants all equipment referenced in this document which is manufactured by Graco and bearing its name to be free from defects in material and workmanship on the date of sale to the original purchaser for use.
