2.2Unpacking

Keep the transmitter in its original packaging to prevent it from being damaged during shipment. Do not unpack the transmitter until it reaches the installation site.

2.3Storage

The following precautions must be observed when storing the instrument, especially for a long period.

(a)Select a storage area which meets the following conditions:

•It is not exposed to rain or subject to water seepage/leaks.

•Vibration and shock are kept to a minimum.

•It has an ambient temperature and relative humidity within the following ranges.

Ambient temperature:

–40* to 85°C without integral indicator

–30* to 80°C with integral indicator

* –15°C when /HE is specified.

Relative humidity: 0% to 100% R.H.

Preferred temperature and humidity: approx. 25°C and 65% R.H.

(b)When storing the transmitter, repack it carefully in the packaging that it was originally shipped with.

(c)If the transmitter has been used, thoroughly clean the chambers inside the cover flanges, so that there is no process fluid remaining inside. Before placing it in storage, also make sure that the pressure-detector is securely connected to the transmitter section.

2.4Selecting the Installation Location

The transmitter is designed to withstand severe environmental conditions. However, to ensure that it will provide years of stable and accurate performance, take the following precautions when selecting the installation location.

(a)Ambient Temperature

Avoid locations subject to wide temperature variations or a significant temperature gradient. If the location is exposed to radiant heat from plant equipment, provide adequate thermal insulation and/or ventilation.

(b)AmbientAtmosphere

Do not install the transmitter in a corrosive atmosphere. If this cannot be avoided, there must be adequate ventilation as well as measures to prevent the leaking of rain water and the presence of standing water in the conduits.

(c)Shock and Vibration

Although the transmitter is designed to be relatively resistant to shock and vibration, an installation site should be selected where this is kept to a minimum.

(d)Installation of Explosion-protected Transmitters An explosion-protected transmitters is certified for installation in a hazardous area containing specific gas types. See subsection 2.9 “Installation of an Explosion-Protected Transmitters.”

2.5Pressure Connection

WARNING

•Never loosen the process connector bolts when an instrument is installed in a process. The device is under pressure, and a loss of seal can result in a sudden and uncontrolled release of process fluid.

•When draining toxic process fluids that have condensed inside the pressure detector, take appropriate steps to prevent the contact of such fluids with the skin or eyes and the inhalation of vapors from these fluids.

The following precautions must be observed in order to safely operate the transmitter under pressure.

(a)Make sure that all the process connector bolts are tightened firmly.

(b)Make sure that there are no leaks in the impulse piping.

(c)Never apply a pressure higher than the specified maximum working pressure.

2.6Waterproofing of Cable Conduit Connections

Apply a non-hardening sealant to the threads to waterproof the transmitter cable conduit connections. (See figure 6.8, 6.9 and 6.10.)

2.7Restrictions on Use of Radio Transceivers

IMPORTANT

Although the transmitter has been designed to resist high frequency electrical noise, if a radio transceiver is used near the transmitter or its external wiring, the transmitter may be affected by high frequency noise pickup. To test this, start out from a distance of several meters and slowly approach the transmitter with the transceiver while observing the measurement loop for noise effects. Thereafter use the transceiver outside the range where the noise effects were first observed.

2.8Insulation Resistance and Dielectric Strength Test

Since the transmitter has undergone insulation resistance and dielectric strength tests at the factory before shipment, normally these tests are not required. If the need arises to conduct these tests, heed the following:

(a)Do not perform such tests more frequently than is absolutely necessary. Even test voltages that do not cause visible damage to the insulation may degrade the insulation and reduce safety margins.

(b)Never apply a voltage exceeding 500 V DC (100 V DC with an internal lightning protector) for the insulation resistance test, nor a voltage exceeding 500 VAC (100 VAC with an internal lightning protector) for the dielectric strength test.

(c)Before conducting these tests, disconnect all signal lines from the transmitter terminals. The procedure for conducting these tests is as follows:

•Insulation Resistance Test

1)Short-circuit the + and – SUPPLY terminals in the terminal box.

2)Turn OFF the insulation tester. Then connect the insulation tester plus (+) lead wire to the shorted SUPPLY terminals and the minus (–) leadwire to the grounding terminal.

3)Turn ON the insulation tester power and measure the insulation resistance. The voltage should be applied as briefly as possible to verify that the insulation resistance is at least 20 MΩ.

4)After completing the test and being very careful not to touch exposed conductors disconnect the insulation tester and connect a 100 kΩ resistor between the grounding terminal and the shortcircuiting SUPPLY terminals. Leave this resistor connected at least one second to discharge any static potential. Do not touch the terminals while it is discharging.

•Dielectric Strength Test

1)Short-circuit the + and – SUPPLY terminals in the terminal box.

2)Turn OFF the dielectric strength tester. Then connect the tester between the shorted SUPPLY terminals and the grounding terminal. Be sure to connect the grounding lead of the dielectric strength tester to the ground terminal.

3)Set the current limit on the dielectric strength tester to 10 mA, then turn ON the power and gradually increase the test voltage from ‘0’to the specified voltage.

4)When the specified voltage is reached, hold it for one minute.

5)After completing this test, slowly decrease the voltage to avoid any voltage surges.

4.2Mounting

■The transmitter is shipped with the process connection, according to the ordering specifications. To change the orientation of the process connections, refer to section 4.3.

■With differential pressure transmitters, the distance between the impulse piping

connection ports is usually 54 mm (figure 4.1). By changing the orientation of the process connector, the dimension can be changed to 51 mm or 57 mm.

■The transmitter can be mounted on a nominal 50 mm (2-inch) pipe using the mounting bracket supplied, as shown in figure 4.2 and 4.3 The transmitter can be mounted on either a horizontal or a vertical pipe.

■When mounting the bracket on the transmitter, tighten the (four) bolts that hold the transmitter with a torque of approximately 39 N·m {4kgf·m}.

4.3Changing 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. Wrap sealing tape around the drain (vent) plug threads (*1 in the figure below), and apply a lubricant to the threads of the drain (vent) screw(s) (*2 below). To tighten the drain (vent) plugs, apply a torque of 34 to 39 N·m (3.5 to 4 kgf·m). Process connector bolts are to be tightened uniformly to a torque shown in table 4.1.

IMPORTANT

This section is applicable only for EJ110, EJ120, and EJ130differential transmitters, and not applicable for gauge or absolute pressure transmitters.

4.4.1Rotating 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 anAllen wrench (JIS B4648, nominal 2.5 mm) to remove the two setscrews at the joint between the pressure-detector section and transmitter section.

2)Leaving the transmitter section in position, rotate the pressure-detector section 180°.

3)Tighten the two setscrews to fix the pressuredetector section and transmitter section together (at a torque of 1.5 N·m). Reposition the process connector and drain

(vent) plugs to the opposite side as described in subsection 4.3.

4.4.2 Using the Communicator

This method is applicable only to the Model EJ110, EJ120, and EJ130.

With a communicator, you can change which process connection is used as the high-pressure side without mechanically rotating the pressuredetector section 180 as described in subsection 4.4.1. To change, call parameter ‘D15: H/LSWAP’ for BRAIN Communication or ‘H/Lswap’for HART Communication and select REVERSE (right side: low pressure; left side: high pressure) or select NORMALto change back to normal (right side: high pressure; left side: low pressure).

F0406.ai

Figure 4.6 Input/Output Relationship

IMPORTANT

Since the H/Llabel plate on the capsule assembly will remain unchanged, use this function only when you cannot switch the impulse piping. If the ‘H/LSWAP’parameter setting is changed, the input/output relationship is reversed as shown in figure 4.6; be sure this is understood by all.

4.5Rotating 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 theAllen wrench.

2)Rotate the transmitter section slowly and stop it at designated position.

3)Tighten the two setscrews to a torque of 1.5 N·m.
