2.4 Selecting 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 signicant temperature gradient. If the location is exposed to radiant heat from plant equipment, provide adequate thermal insulation and/or ventilation.

(b) Ambient Atmosphere

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.

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 certied for installation in a hazardous area containing specic gas types. See subsection

2.9 “Installation of an Explosion-Protected Transmitters.”

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 rmly.

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

piping.

specied maximum working pressure.

2.6 Waterproong of Cable Conduit Connections

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

2.7 Restrictions 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 rst observed.

2.5 Pressure 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 uid.

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

2.8 Insulation 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.

IM 01C25B01-01E

<2. Handling Cautions>

2-3

(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 V AC (100 V AC with an internal lightning protector) for the dielectric strength test.

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 briey 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.

2.9 Installation of an ExplosionProtected Instrument

NOTE

For FOUNDATION Fieldbus explosion protected type, please refer to IM 01C22T02-01E. For PROFIBUS PA explosion protected type, please refer to IM 01C25T04-01EN.

If a customer makes a repair or modication to an intrinsically safe or explosionproof instrument and the instrument is not restored to its original condition, its intrinsically safe or explosionproof construction may be compromised and the instrument may be hazardous to operate. Please contact Yokogawa before making any repair or modication to an instrument.

CAUTION

This instrument has been tested and certied as being intrinsically safe or explosionproof. Please note that severe restrictions apply to this instrument’s construction, installation, external wiring, maintenance and repair. A failure to abide by these restrictions could make the instrument a hazard to operate.

• 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 specied voltage.

4) When the specied voltage is reached, hold it for one minute.

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

WARNING

Maintaining the safety of explosionproof equipment requires great care during mounting, wiring, and piping. Safety requirements also place restrictions on maintenance and repair. Please read the following sections very carefully.

WARNING

The range setting switch must not be used in a hazardous area.

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 non-conductive pollution occurs. Occasionally, however, temporary conductivity caused by condensation must be expected.

(2) Installation Category I

"Overvoltage category (Installation category)" describes a number which denes a transient overvoltage condition. It implies the regulation for impulse withstand voltage. " I " applies to electrical equipment which is supplied from the circuit when appropriate transient overvoltage control means (interfaces) are provided.

■ The transmitter is shipped with the process connection, according to the ordering specications. 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 (gure 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 gure 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}.

Figure 4.1 and 4.2 shows the mounting of the transmitter for horizontal piping and vertical piping with using the mounting bracket. The transmitters with the installation code -U (Universal ange) can be used for either type of mounting.

4.3 Changing the Process Connection

The transmitter is shipped with the process connection specied 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 gure 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.

4.4 Swapping the High/Lowpressure Side Connection

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.

4.4.1 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 eld after making the change.

1) Use an Allen 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 x 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/L SWAP’ for BRAIN Communication or ‘H/L swap’ for HART Communication and select REVERSE (right side: low pressure; left side: high pressure) or select NORMAL to change back to normal (right side: high pressure; left side: low pressure).

IMPORTANT

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

4.5 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 conguration of the instrument.) It can be xed 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.

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

IMPORTANT

Do not rotate the transmitter section more than the above limit.
