2. HANDLING CAUTIONS2.HANDLING CAUTIONSThis chapter describes important cautions regardinghow to handle the transmitter. Read carefully beforeusing the transmitter.mode was ordered, ‘SQRT’ is inscribed in field *2; ifsquare root output mode was ordered, ‘SQRT’ isinscribed in field *3.The EJA-A Series pressure transmitters are thoroughlytested at the factory before shipment. When thetransmitter is delivered, visually check them to makesure that no damage occurred during ship-ment.Also check that all transmitter mounting hardwareshown in Figure 2.1 is included. If the transmitter wasordered without the mounting bracket or without theprocess connector, the transmitter mounting hardwareis not included. After checking the transmitter, repackit in the way it was delivered until installation.BoltProcess connectorProcess connectorGasket: Refer to USER'S MANUALF0202.EPSFigure 2.2 Name Plate2.2 UnpackingWhen moving the transmitter to the installation site,keep it in its original packaging. Then, unpack thetransmitter there to avoid damage on the way.2.3 StorageU-boltThe following precautions must be observed whenstoring the instrument, especially for a long period.Mounting bracket(L type)U-bolt nutTransmitter mounting bolt(a) Select a storage area which meets the followingconditions: It is not exposed to rain or water. It suffers minimum vibration and shock. It has an ambient temperature and relativehumidity within the following ranges.Ambient temperature:–40 to 85 C without integral indicator–30 to 80 C with integral indicatorRelative humidity:5% to 100% R.H. (at 40 C)Preferred temperature and humidity:approx. 25 C and 65% R.H.Mounting bracket(Flat type)F0201.EPSFigure 2.1 Transmitter Mounting Hardware2.1 Model and SpecificationsCheck(b) When storing the transmitter, repack it as nearly aspossible to the way it was packed when deliveredfrom the factory.(c) If storing a transmitter that has been used, thoroughly clean the chambers inside the cover flanges,so that no measured fluid remains in it. Also makesure before storing that the pressure-detector andtransmitter section are securely mounted.The model name and specifications are indicated on thename plate attached to the case. If the reverse operating mode was ordered (reverse signal), ‘REVERSE’will be inscribed in field *1; if square root display2-1IM 01C21B01-01E
2. HANDLING CAUTIONS2.4 Selecting the InstallationLocationCAUTIONMaximum working pressure of the modelEJA120A differential pressure transmitter is 50kPa {0.5 kgf/cm2}.Should the pressure exceed 50 kPa {0.5 kgf/cm2}, it is possible to break the sensor. Proceedwith caution when applying pressure.The transmitter is designed to withstand severeenvironmental conditions. However, to ensure stableand accurate operation for years, observe the followingprecautions when selecting an installation location.(a) Ambient TemperatureAvoid locations subject to wide temperaturevariations or a significant temperature gradient. Ifthe location is exposed to radiant heat from plantequipments, provide adequate thermal insulationand/or ventilation.(b) Ambient AtmosphereAvoid installing the transmitter in a corrosiveatmosphere. If the transmitter must be installed in acorrosive atmosphere, there must be adequateventilation as well as measures to prevent intrusionor stagnation of rain water in conduits.(c) Shock and VibrationSelect an installation site suffering minimum shockand vibration (although the transmitter is designedto be relatively resistant to shock and vibration).2.6 Waterproofing of CableConduit ConnectionsApply a non-hardening sealant to the threads towaterproof the transmitter cable conduit connections.(See Figure 6.4.2a, 6.4.2b and 6.4.2c.)2.7 Restrictions on Use of RadioTransceiverIMPORTANTAlthough the transmitter has been designed toresist high frequency electrical noise, if a radiotransceiver is used near the transmitter or itsexternal wiring, the transmitter may be affectedby high frequency noise pickup. To test for sucheffects, bring the transceiver in use slowly from adistance of several meters from the transmitter,and observe the measurement loop for noiseeffects. Thereafter, always use the transceiveroutside the area affected by noise.(d) Installation of Explosion-protected TransmittersExplosion-protected transmitters can be installed inhazardous areas according to the types of gases forwhich they are certified. See Subsection 2.9“Installation of Explosion Protected Type Transmitters.”2.5 Pressure ConnectionWARNING Instrument installed in the process is underpressure. Never loosen the process connectorbolts to avoid the dangerous spouting ofprocess fluid. During draining condensate from the pressuredetector section, take appropriate care to avoidcontact with the skin, eyes or body, or inhalation of vapors, if the accumulated process fluidmay be toxic or otherwise harmful.The following precautions must be observed in order tosafely operate the transmitter under pressure.(a) Make sure that the four process connector bolts aretightened firmly.(b) Make sure that there are no leaks in the impulsepiping.(c) Never apply a pressure higher than the specifiedmaximum working pressure.2.8 Insulation Resistance andDielectric Strength TestSince the transmitter has undergone insulation resistance and dielectric strength tests at the factory beforeshipment, normally these tests are not required.However, if required, observe the following precautions in the test procedures.(a) Do not perform such tests more frequently than isabsolutely necessary. Even test voltages that do notcause visible damage to the insulation may degradethe insulation and reduce safety margins.(b) Never apply a voltage exceeding 500 V DC (100 VDC with an internal lightning protector) for theinsulation resistance test, nor a voltage exceeding500 V AC (100 V AC with an internal lightningprotector) for the dielectric strength test.2-2IM 01C21B01-01E
2. HANDLING CAUTIONS(c) Before conducting these tests, disconnect all signallines from the transmitter terminals. Perform thetests in the following procedure:and may cause dangerous condition. Please contactYokogawa for any repair or modification required tothe instrument. Insulation Resistance Test1) Short-circuit the and – SUPPLY terminals in theterminal box.2) Turn OFF the insulation tester. Then connect theinsulation tester plus ( ) lead wire to the shortedSUPPLY terminals and the minus (–) leadwire tothe grounding terminal.3) Turn ON the insulation tester power and measurethe insulation resistance. The voltage should beapplied short as possible to verify that the insulation resistance is at least 20 MΩ.4) After completing the test and being very careful notto touch exposed conductors disconnect theinsulation tester and connect a 100 kΩ resistorbetween the grounding terminal and the shortcircuiting SUPPLY terminals. Leave this resistorconnected at least one second to discharge anystatic potential. Do not touch the terminals while itis discharging. Dielectric Strength Test1) Short-circuit the and – SUPPLY terminals in theterminal box.2) Turn OFF the dielectric strength tester. Thenconnect the tester between the shorted SUPPLYterminals and the grounding terminal. Be sure toconnect the grounding lead of the dielectric strengthtester to the ground terminal.3) Set the current limit on the dielectric strength testerto 10 mA, then turn ON the power and graduallyincrease the test voltage from ‘0’ to the specifiedvoltage.4) When the specified voltage is reached, hold it forone minute.5) After completing this test, slowly decrease thevoltage to avoid any voltage surges.2.9 Installation of ExplosionProtected TypeNOTEFor FOUNDATION Fieldbus and PROFIBUS PAexplosion protected type, please refer to IM01C22T02-01E and IM 01C22T03-00E respectively.CAUTIONThis instrument is tested and certified as intrinsically safe type or explosionproof type. Pleasenote that the construction of the instrument,installation, external wiring, maintenance orrepair is strictly restricted, and non-observanceor negligence of this restriction would result indangerous condition.WARNINGTo preserve the safety of explosionproof equi
