Pneumatic Connections Clean all pipelines to remove dirt and scale before installation. Apply a minimum amount of pipe compound to the male threads of the fitting only. Do Not use teflon tape as a sealant. Start with the third thread back and work away from the end of the fitting to avoid the possibility of contaminating the transducer. Install the transducer in the air line. The inlet and outlet ports are labeled on the end of the transducer. Tighten connections securely. Avoid undersized fittings that will limit the flow through the transducer and cause a pressure drop down stream. For more information, see Figure. Outline Drawing on page. NOTES: Instrument quality air, per ISA Standards D7.- 98, is required. Use a filter to remove dirt and liquid in the air line ahead of the transducer for correct performance. If an air line lubricator is used, it MUST be located downstream, beyond the transducer. The user is responsible for insuring that the environment in which the unit will be installed, and the operating gas, are compatible with the materials in the transducer. WARNING: To prevent possible ignition of hazardous atmosphere, DO NOT REMOVE COVER from the TXPD500 Transducer while current is on. To maintain Explosion-Proof capability, DO NOT DAMAGE mating surfaces between cover and base. NEVER ADD GASKETS. Electric Connection For the T500 Transducer, make connections to the Terminal Block through a / NPT Conduit Connector (not supplied) and a plastic sleeve as shown below in Figure 7. Electrical Connections. For the TXPD500 Transducer, make connections from the Sealed Connector Wires to an external Terminal Block. The TXPD500 Transducer has an additional ground wire that is used. For more information, see Figure 7. Electrical Connections below. NOTE: The T500 & TXPD500 should be wired in accordance with the wiring diagram inside of cover. Wiring in Hazardous Areas Wiring in hazardous areas should be performed in accordance with the Table. and any local codes that apply. Table. Hazardous Location Wiring Practices.

Voltage Supply capable of delivering up to 0 VDC. Gage capable of a digital readout up to 50 psig with an accuracy of.%. Digital Volt Meter capable of a readout up to 0 ma or 0 VDC with an accuracy of.0%. The following adjustments are provided: Full Range Operation Forward/Reverse Mode Calibration - Zero and Span FULL RANGE OPERATION Forward Acting Mode Adjustment. Connect the input signal to the transducer as shown in Figure 7. Electrical Connections. NOTE: Air Supply must be connected before adjustments are made. Forward Acting Calibration-Zero. Apply the minimum input signal and adjust the Zero screw for minimum output pressure. Turn screw counterclockwise to increase pressure and clockwise to decrease pressure. Forward Acting Calibration-Span. Apply the maximum input signal and adjust the Span screw on the potentiometer for maximum output pressure. Turn screw clockwise to increase pressure and counterclockwise to decrease pressure.. Repeat steps - until the desired output range is obtained. For more information, see Figure 8. T500/ TXPD500 Calibration Configuration. Reverse Acting Mode Adjustment 5. Reverse the input signal connections to the transducer as shown in Figure 7. Electrical Connections. Reverse Acting Calibration-Zero 6. Apply the minimum input signal and adjust the Zero screw for maximum output pressure. Turn screw counterclockwise to increase pressure and clockwise to decrease pressure. Reverse Acting Calibration-Span 7. Apply the maximum input signal and adjust the Span screw on the potentiometer for minimum output pressure. Turn screw clockwise to increase pressure and counterclockwise to decrease pressure. 8. Repeat steps 6-7 until the desired output range is obtained. For more information, see Figure 8. T500/ TXPD500 Calibration Configuration.

MAINTENANCE To clean the Orifice, use the following procedure:.. Shut off the valve that is supplying air to transducer. Remove the Air Line from the Inlet Port. Remove the Orifice Assembly () from the unit by threading a /-0" Screw into the orifice housing and pulling it out through the inlet port. For more information, see Figure 9. Exploded Drawing below. To clear problems caused by Magnet malfunction, use the following procedure:.. Shut off the valve that is supplying air to transducer. It is not necessary to remove the Transducer from air line. Remove three Screws (5) holding Magnet (6) to Transducer ().. NOTE: Clean with alcohol and dry with compressed air. Parts must be completely dry before reassembling... Remove Magnet (6) and clean gap of any foreign material with masking tape. For more information, see Figure 9. T500 Exploded Drawing below. Place Magnet (6) over Coil (7) and tighten with three Screws (5). To replace PC Board, use the following procedure:.... Disconnect wires from Terminal Block on PC Board (). Unsolder Red () and Black (-) Leads on PC Board (). Remove four Screws () holding PC Board () to Transducer (). For more information, see Figure 9. Exploded Drawing below. Replace PC Board () with the appropriate PC Board from Table. on page 9. 5. Using a non-metallic rod, raise up on the arm to make sure Coil (7) is free to move in Magnet (6). NOTES: If Coil is sticking or dragging, loosen Screws and reposition Magnet. Tighten Screws and repeat step 5. If the standard maintenance procedure does not correct the problem, install Service Kit.
