4. 4.1 <4. Installation> 4-1 Installation Precautions Before installing the transmitter, read the cautionary notes in section 2.4, “Selecting the Installation Location.” For additional information on the ambient conditions allowed at the installation location, refer to section 9.1 “Standard Specifications.
4-2 <4. Installation> Transmitter section IMPORTANT Tighten the hexagonal nut part of the capsule assembly. See Figure 4.3. Setscrew Capsule assembly Pressure-detector section Stopper Figure 4.4 F0404.ai Rotating Transmitter Section F0403.ai Figure 4.3 4.
5. 5.1 5-1 <5. 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 liquidfilled impulse line, or the drain for a gas-filled impulse line becomes plugged, it will not convey the pressure accurately.
<5. Installing Impulse Piping> (3) Impulse Piping Slope Tap valve The impulse piping must be routed with only an upward or downward slope. Even for horizontal routing, the impulse piping should have a slope of at least 1/10 to prevent condensate (or gases) from accumulating in the pipes.
6-1 <6. Wiring> 6.1 Wiring Precautions 6.3 IMPORTANT • Lay wiring as far as possible from electrical noise sources such as large capacity transformers, motors, and power supplies. • Remove the electrical connection dust cap before wiring. • All threaded parts must be treated with waterproofing sealant. (A non-hardening silicone group sealant is recommended.) • To prevent noise pickup, do not pass signal and power cables through the same ducts.
6-2 <6. Wiring> 6.3.4 Check Meter Connection (1) General-use Type and Flameproof Type Available only when /AL is not specified. Hazardous Location Connect the check meter to the CHECK + and – terminals. (Use hooks.) Transmitter terminal box Distributor (Power supply unit) PULSE • A 4 to 20 mA DC output signal from the CHECK + and – terminals. Nonhazardous Location SUPP LY CHECKM ALAR Receiver instrument (Note) Use a check meter whose internal resistance is 10 Ω or less.
6-3 <6. Wiring> (2) Flameproof Type 6.5 Wire cables through a flameproof packing adapter, or use a flameproof metal conduit. 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. ■ Wiring cable through flameproof packing adapter.
7-1 <7. Operation> 7. Operation 7.1 Preparation for Starting Operation Tap valve Vent plug (Fill plug) This section describes the operation procedure for the EJ530 as shown in figure 7.1. Union or flange NOTE Stop valve Check that the process pressure tap valves, drain valves, and stop valves are closed. (a) Follow the procedures below to introduce process pressure into the impulse piping and transmitter. 1) Open the tap valve (main valve) to fill the impulse piping with process fluid.
7-2 <7. Operation> Using the integral indicator • If the wiring system is faulty, the display stays blank. • If the transmitter is faulty, an error code is displayed. IMPORTANT Do not turn off the power to the transmitter immediately after performing a zero point adjustment. Powering off within 30 seconds of performing this procedure will return the zero point to its previous setting. NOTE Self-diagnostic error on the integral indicator (Faulty transmitter) Figure 7.3 F0703.
Use a slotted screwdriver to turn the zeroadjustment screw. 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. Since the degree of the zero adjustment varies with the screw turning speed, turn the screw slowly to make a fine adjustment and quickly to make a rough adjustment.
7.5 Setting the Range Using the Range-setting Switch WARNING The range setting switch must not be used in the hazardous area. When it is necessary to use the switch, operate it in a non-hazardous location. <7. Operation> 7-4 Note 1: Wait until the pressure inside the pressure-detector section has stabilized before proceeding to the next step. Note 2: If the pressure applied to the transmitter exceeds the previous LRV (or URV), the integral indicator may display error number “AL.
8. 8.1 Maintenance Overview 8.3 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.
