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.
4.4 4-3 <4. Installation> Swapping the High/Lowpressure Side Connection IMPORTANT This section is applicable only for EJ110, EJ120, and EJ130 differential transmitters, and not applicable for gauge or absolute pressure transmitters. 4.4.1 Rotating Pressure-detector Section 180° This procedure can be applied only to a transmitter with a vertical impulse piping type. 4.4.2 Using the Communicator This method is applicable only to the Model EJ110, EJ120, and EJ130.
4.5 4-4 <4. 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.
5. 5.1 5-1 <5. Installing Impulse Piping> Installing Impulse Piping Impulse Piping Installation Precautions (2) Changing the Process Connector Piping Connections (Figure 4.1) (for differential pressure transmitters) 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.
5-2 <5. Installing Impulse Piping> Pipe-Mounting Type 3-Valve Manifold (Figure 5.2) Direct-Mounting Type 3-Valve Manifold (Figure 5.3) 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 (2inch) pipe by fastening a U-bolt to its mounting bracket.
5.1.2 Routing the Impulse Piping (3) Impulse Piping Slope (1) Process Pressure Tap Angles If condensate, gas, sediment or other extraneous material in the process piping gets into the impulse piping, pressure measurement errors may result. To prevent such problems, the process pressure taps must be angled as shown in figure 5.4 according to the kind of fluid being measured. NOTE • If the process fluid is a gas, the taps must be vertical or within 45° either side of vertical.
(7) Preventing Freezing If there is any risk that the process fluid in the impulse piping or transmitter could freeze, use a steam jacket or heater to maintain the temperature of the fluid. NOTE After completing the connections, close the valves on the process pressure taps (main valves), the valves at the transmitter (stop valves), and the impulse piping drain valves, so that condensate, sediment, dust and other extraneous material cannot enter the impulse piping. 5.
6-1 <6. Wiring> 6. Wiring 6.1 Wiring Precautions 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.

6.5 <6. Wiring> 6-5 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. Ground terminals are located on the inside and outside of the terminal box. Either of these terminals may be used. Ground terminal (inside) Ground terminal (outside) F0611.ai Figure 6.16 6.

7.2 Zero Point Adjustment After completing preparations for operating the transmitter, adjust the zero point. Zero point adjustment can be done by turning the transmitter’s zero-adjustment screw or by using the communicator. This section describes the procedure for the zero-adjustment screw. For the communicator procedure, see the communication manual. IMPORTANT Do not turn off the power to the transmitter immediately after performing a zero point adjustment.
(2) When you cannot obtain the Low Range Value from the actual measured value of 0%; Adjust the transmitter output to the actual measured value obtained by a digital manometer or a glass gauge. [Example] The measuring range of 50 to 250 kPa; the actual measured value of 130 kPa.
