16 <2. Handling Cautions> 2.6 Pressure Equipment Directive (PED) (1) General • EJX/EJA-E Series pressure transmitters are categorized as piping under the pressure accessories section of directive 97/23/EC, which corresponds to Article 3, Paragraph 3 of PED, denoted as Sound Engineering Practice (SEP).
<2. Handling Cautions> 2.7 17 Low Voltage Directive Applicable standard: EN61010-1 (1) Pollution Degree 2 "Pollution degree" describes the degree to which a solid, liquid, or gas which deteriorates dielectric strength or surface resistivity is adhering. " 2 " applies to normal indoor atmosphere. Normally, only nonconductive pollution occurs. Occasionally, however, temporary conductivity caused by condensation must be expected.
18 <3. Installation> 3. Installation Vertical pipe mounting (Process connector upside) IMPORTANT • When welding piping during construction, take care not to allow welding currents to flow through the transmitter. • Do not step on this instrument after installation. • For EJ430, EJ440 and EJ438, the atmospheric opening is located on the low pressure side cover flange.
19 <3. Installation> 3.3 3.2.1 EJ210 The transmitter is mounted on a process using its high pressure side flange as shown in Figure 3.5. The customer should prepare the mating flange, gasket, stud bolts and nuts. Gasket Stud bolt Nut Figure 3.5 F0305.ai EJ210 Mounting 3.2.2 EJ118 and EJ438 Mount the diaphragm seals using the flanges as shown in Figure 3.6. The mating flange, gasket, bolts and nuts are to be procured by the customer.
20 <3. Installation> Low pressure side IMPORTANT The transmitter should be installed at least 600 mm below the high pressure (HP) process connection to ensure a positive head pressure of fill fluid. Pay special attention to vacuum applications. If it can not be installed at least 600 mm below the HP process connection, please use the equation below: h= h High (+) pressure side 0 (P–P0) × 0.
21 <3. Installation> 3.5 3.4.2 Mounting to Process Flange Tighten the bolts to completely close the gap between the ring and the pressure detector section. The mating flange, gasket, stud bolts and nuts are to procured by the customer. Spiral gasket Mating flange Ring Diaphragm Gasket Pressure-detector section Affixing the Teflon Film IMPORTANT The FEP Teflon option includes a teflon film and fluorinated oil.
22 <3. Installation> 3.6 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.
23 <4. Installing Impulse Piping> 4. 4.1 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 of a gas-filled impulse line becomes plugged, it will not convey the pressure accurately.
24 <4. Installing Impulse Piping> 1) Screw nipples into the connection ports on the transmitter side of the 3-valve manifold, and into the impulse piping connecting ports on the process connectors. (To maintain proper sealing, wind sealing tape around the nipple threads.) 2) Mount the 3-valve manifold on the 50 mm (2-inch) pipe by fastening a U-bolt to its mounting bracket. Tighten the U-bolt nuts only lightly at this time.
25 <4. Installing Impulse Piping> (4) Temperature Difference Between Impulse Piping (for differential pressure transmitters) If there is a temperature difference between the high and low impulse lines, the density difference of the fluids in the two lines will cause an error in the measurement pressure. When measuring flow, impulse lines must be routed together so that there is no temperature difference between them.

30 <5. Wiring> 5.2.5 External Temperature Connection (for EJX910A and EJX930A) (2) Intrinsically Safe Type Connect the RTD cable assembly to the Juck Terminal. With the intrinsically safe type, a safety barrier must be included in the loop. Hazardous Location PULS E Transmitter terminal box SUPP CHECK ALARM F0505.ai Figure 5.5 5.
31 <5. Wiring> 5.3.2 Wiring Installation Non-hazardous area Gas sealing device (1) General-use Type and Intrinsically Safe Type With the cable wiring, use a metallic conduit or waterproof glands. • Apply a non-hardening sealant to the terminal box connection port and to the threads on the flexible metal conduit for waterproofing.
32 <5. Wiring> (4) Insert the RTD cable and firmly plug its connector into the connecting port in the transmitter's terminal box. PULS E • Components for the cable gland The cable gland assembly consists of an entry, seal, running coupler, and backnut. Confirm that the seal is attached inside the entry and that the thread size of the cable gland is the same as that for the RTD electrical connection. SUPP LY CHECKM ALAR 1/2NPT Type Running Coupler Entry with Seal Backnut F0519.

Wiring> 5.4.2 Connecting Shielded Cable for Conduit Use (External temperature input code: -B, -C, and -D) • RTD connection components: EJX multivariable transmitter and RTD cable 5.4.3 Cable Connection RTD Terminal Box Side EJX multivariable transmitter RTD I/F is for 3-wire Type RTD, Pt100. Heed the following when wiring an RTD of the 2- or 4-wire type. NOTE F0522.ai Please note that a temperature error will occur when you use a 2-wire RTD because of wiring resistance.
<5. Wiring> 5.5 34 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) F0525.
