5. 5.1 5-1 <5. Installation> Installation Precautions Vertical pipe mounting Before installing the transmitter, read the cautionary notes in section 3.4, “Selecting the Installation Location.” For additional information on the ambient conditions allowed at the installation location, refer to subsection 10.1 “Standard Specifications.” Transmitter mounting bolt IMPORTANT • When welding piping during construction, take care not to allow welding currents to flow through the transmitter.
5-2 <5. Installation> 5.3 Vertical pipe mounting (Process connector downside) Transmitter mounting bolt Mounting bracket 50 mm(2-inch) pipe U-bolt nut Changing the Process Connection The transmitter is shipped with the process connection specified at the time of ordering. To change the process connection, the drain (vent) plug must be repositioned. To reposition a drain (vent) plug, use a wrench to slowly and gently unscrew it. Then, remove and remount it on the opposite side.
5.4 5-3 <5. Installation> Swapping the High/Lowpressure Side Connection 5.4.1 Rotating Pressure-detector Section 180° This procedure can be applied only to a transmitter with a vertical impulse piping type. The procedure below can be used to turn the pressure detector assembly 180°. Perform this operation in a maintenance shop with the necessary tools laid out and ready for use, and then install the transmitter in the field after making the change. 1) Use an Allen wrench (JIS B4648, nominal 2.
5.5 5-4 <5. Installation> Rotating Transmitter Section The transmitter section can be rotated approximately 360° (180° to either direction or 360° to one direction from the original position at shipment, depending on the configuration of the instrument.) It can be fixed at any angle within above range. 1) Remove the two setscrews that fasten the transmitter section and capsule assembly, using the Allen wrench. 2) Rotate the transmitter section slowly and stop it at designated position.
6. 6.1 6-1 <6. Installing Impulse Piping> Installing Impulse Piping Impulse Piping Installation Precautions The impulse piping that connects the process outputs to the transmitter must convey the process pressure accurately. If, for example, gas collects in a liquid-filled impulse line, or the drain for a gas-filled impulse line becomes plugged, it will not convey the pressure accurately.
4) Now tighten the nuts and bolts securely in the following sequence: Process connector bolts → transmitter-end ball head lock nuts → 3-valve manifold ball head lock nuts → 3-valve manifold mounting bracket U-bolt nuts Impulse piping Nipple Vent plug (optional) 3-valve manifold Stop valve (low pressure side) Equalizing valve (balancing) Ball head lock nut Pipe Pipes Stop valve (high pressure side) Ball head lock nut Nipple 50 mm(2-inch) pipe Process connector Process connector bolts F0602.
(2) Position of Process Pressure Taps and Transmitter If condensate (or gas) accumulates in the impulse piping, it should be removed periodically by opening the drain (or vent) plugs. However, this will generate a transient disturbance in the pressure measurement, and therefore it is necessary to position the taps and route the impulse piping so that any extraneous liquid or gas generated in the leadlines returns naturally to the process piping.
6.2 <6. Installing Impulse Piping> 6-4 Impulse Piping Connection Examples Figure 6.5 shows examples of typical impulse piping connections. Before connecting the transmitter to the process, study the transmitter installation location, the process piping layout, and the characteristics of the process fluid (corrosiveness, toxicity, flammability, etc.), in order to make appropriate changes and additions to the connection configurations. Note the following points when referring to these piping examples.
7-1 <7. Wiring> 7. Wiring 7.1 Wiring Precautions 7.2 IMPORTANT (a) Use stranded leadwires or cables which are the same as or better than 600 V grade PVC insulated wire or its equivalent. (b) Use shielded wires in areas that are susceptible to electrical noise. (c) In areas with higher or lower ambient temperatures, use appropriate wires or cables. (d) In environment where oils, solvents, corrosive gases or liquids may be present, use wires or cables that are resistant to such substances.

7-7 <7. Wiring> (4) Secure the RTD cable to the packing box by screwing the gland into the packing box at the position where the distance from the connector tip of the RTD cable to the packing box will be 56.5±1mm. Tighten approximately 1 more turn surely after the cable can not move. The quantity of this tightening is very important. It leads to wiring disconnection fault when tighten too much. After that, tighten the clamp nut. 7.6.
7.6.3 Removing Shielded Cable with Cable Gland (External temperature input code: -1, -2, -3, and -4) (1) By pulling out the string attached to the connector, carefully unplug the connector from the transmitter’s connecting port. (2) In the case of using 1/2NPT Type or M20 Type cable gland, remove the running coupler and backnut assembly by turning the running coupler. In the case of using G1/2 Type cable gland, loosen the lock nut screwed into the union cover and remove the union cover.
7.7 <7. Wiring> 7-9 Grounding Grounding is always required for the proper operation of transmitters. Follow the domestic electrical requirements as regulated in each country. For a transmitter with a built-in lightning protector, grounding should satisfy ground resistance of 10Ω or less. PULS E Ground terminals are located on the inside and outside of the terminal box. Either of these terminals may be used. SUPP LY Ground terminal (inside) CHECK ALARM Ground terminal (outside) F0724.

The zero-adjustment screw is located inside the cover. Use a slotted screwdriver to turn the zeroadjustment screw. Equalize the transmitter, then turn the screw clockwise to increase the output or counterclockwise to decrease the output. The zero point adjustment can be made with a resolution of 0.01% of the setting range. The degree of zero adjustments varies with the screw turning speed; turn the screw slowly to make a fine adjustment, quickly to make a rough adjustment. 8.2.
8.3 Starting Operation After completing the zero point adjustment, follow the procedures below to start operation. Steps 1) and 2) are specific to the differential pressure transmitters. 1) Close the equalizing valve. 2) Gradually open the low pressure stop valve. This places the transmitter in an operational condition. 3) Confirm the operating status.
<8. Operation> 8-5 8.5.1 Draining Condensate 1) Gradually open the drain screw or drain plug and drain the transmitter pressure-detector section. (See figure 8.4) 2) When all accumulated liquid is completely removed, close the drain screw or drain plug. 3) Tighten the drain screw to a torque of 10 N·m, and the drain plug to a torque of 34 to 39 N·m. Drain plug Drain screw When you loosen the drain screw or drain plug, the accumulated liquid will be expelled in the direction of the arrow. F0805.
9. 9.1 Maintenance Overview 9.3 WARNING Use the procedure below to check instrument operation and accuracy during periodic maintenance or troubleshooting. Since the accumulated process fluid may be toxic or otherwise harmful, take appropriate care to avoid contact with the body or inhalation of vapors when draining condensate or venting gas from the transmitter pressure-detector section and even after dismounting the instrument from the process line for maintenance.
9.3.2 External Temperature (RTD) Using a thermometer resistor as input, calibration of the temperature transmitter is carried out via a 3-core wire connection. As defined the reference resistor value table of the thermometer resistor (RTD), obtain resistance values corresponding to 0, 25, 50, 75 or 100% of the span, and use the obtained resistance as the input value, then deliver it to the temperature transmitter by means of a variable resistor.
