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.

2.1Model and Specifications Check

The model name and specifications are written on the name plate attached to the case.

F0202.ai

Figure 2.2 Name Plate

(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.

IM 01C25F01-01E

<2. Handling Cautions>	2-2

(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.

IM 01C25F01-01E

<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 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.

2.9Installation of an ExplosionProtected Instrument

NOTE

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

For PROFIBUS PAexplosion protected type, please refer to IM 01C25T04-01EN.
