HANDLING CAUTIONS 2. HANDLING CAUTIONS This chapter describes important cautions regarding how to handle the transmitter. Read carefully before using the transmitter. The EJA Series pressure transmitters are thoroughly tested at the factory before shipment. When the transmitter is delivered, visually check them to make sure that no damage occurred during shipment. Also check that all transmitter mounting hardware shown in Figure 2.1 is included. If the transmitter was ordered without the mounting bracket, the transmitter mounting hardware is not included. After checking the transmitter, repack it in the way it was delivered until installation. Transmitter mounting bolt 2.2 Unpacking When moving the transmitter to the installation site, keep it in its original packaging. Then, unpack the transmitter there to avoid damage on the way. 2.3 Storage 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 water. • It suffers minimum vibration and shock. • 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 Relative humidity: 5% to 100% R.H. (at 40°C) Preferred temperature and humidity: approx. 25°C and 65% R.H. U-bolt U-bolt nut Mounting bracket F0201.EPS Figure 2.1 Transmitter Mounting Hardware 2.1 Model and Specifications Check (b) When storing the transmitter, repack it as nearly as possible to the way it was packed when delivered from the factory. (c) If storing a transmitter that has been used, thoroughly clean the diaphragm surface of the diaphragm seal (pressure-detector section), so that no measured fluid remains on them. Also make sure before storing that the pressure-detector and transmitter assemblies are securely mounted. The model name and specifications are indicated on the name plate attached to the case. If the reverse operating mode was ordered (reverse signal), ‘REVERSE’ will be inscribed in field *1; if square root display mode was ordered, ‘SQRT’ is inscribed in field *2; if square root output mode was ordered, ‘SQRT’ is inscribed in field *3. Figure 2.2 Name Plate Example of JIS Flameproof Type 2-1 IM 1C22H1-01E 2. HANDLING CAUTIONS 2.4 Selecting the Installation Location The following precautions must be observed in order to safely operate the transmitter under pressure. The transmitter is designed to withstand severe environmental conditions. However, to ensure stable and accurate operation for years, observe the following precautions when selecting an installation location. (a) Never apply a pressure higher than the specified maximum working pressure. (b) Never loosen or tighten the bolts securing the diaphragm seal flanges when the assembly is under pressure. Do it after releasing the process pressure if required. (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 equipments, provide adequate thermal insulation and/or ventilation. (b) Ambient Atmosphere Avoid installing the transmitter in a corrosive atmosphere. If the transmitter must be installed in a corrosive atmosphere, there must be adequate ventilation as well as measures to prevent intrusion or stagnation of rain water in conduits. 2.6 Waterproofing of Cable Conduit Connections Apply a non-hardening sealant to the threads to waterproof the transmitter cable conduit connections. (See Figure 5.4.2a, 5.4.2b and 5.4.2d.) 2.7 Restrictions on Use of Radio Transceiver (c) Shock and Vibration Select an installation site suffering minimum shock and vibration (although the transmitter is designed to be relatively resistant to shock and vibration). 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 for such effects, bring the transceiver in use slowly from a distance of several meters from the transmitter, and observe the measurement loop for noise effects. Thereafter, always use the transceiver outside the area affected by noise. (d) Installation of Explosion-protected Transmitters Explosion-protected transmitters can be installed in hazardous areas according to the types of gases for which they are certified. See Subsection 2.9 “Installation of Explosion Protected Type Transmitters.” 2.5 Pressure Connection WARNING • Instrument installed in the process is under pressure. Never loosen or tighten the flange bolts to avoid the dangerous spouting of process fluid. • Since the accumulated process fluid may be toxic or otherwise harmful, take appropriate care to avoid contact with the skin, eyes or body, or inhalation of vapors even after dismounting the instrument from process line for maintenance. 2-2 IM 1C22H1-01E 2. HANDLING CAUTIONS 2.8 Insulation Resistance and Dielectric Strength Test 5) After completing this test, slowly decrease the voltage to avoid any voltage surges. Since the transmitter has undergone insulation resistance and dielectric strength tests at the factory before shipment, normally these tests are not required. However, if required, observe the following precautions in the test procedures. 2.9 Installation of Explosion Protected Type NOTE (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 V AC (100 V AC with an internal lightning protector) for the dielectric strength test. (c) Before conducting these tests, disconnect all signal lines from the transmitter terminals. Perform the tests in the following procedure: • 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 short 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. For FOUNDATION Fieldbus explosion protected type, please refer to IM 1C22T2-01E. WARNING To pressure the safety of explosionproof equipment requires great care during mounting, wiring, and piping. Safety requirements also place restrictions on maintenance and repair activities. Please read the following sections very carefully. 2.9.1 FM Approval a.

INSTALLATION 4.1 Precautions IMPORTANT j Before installing the transmitter, read the cautionary notes in Section 2.4, “Selecting the Installation Location.” For additional information on the ambient conditions allowed at the installation location, refer to Subsection 9.1 “Standard Specifications.” • When measuring the liquid level of the tank, the minimum liquid level (zero point) must be set to a level at least 50 mm above the center of the high pressure side diaphragm seal (see Figure 4.2.2). • Correctly install the diaphragm seals on the high and low pressure sides of the process, checking the label on each seal. • To avoid measuring error duets temperature difference between the two diaphragm seals, capillary tube must be bound together. The capillary tube must be securely fixed to the tank wall to prevent movement by wind or vibration. If the capillary tube are too long, loosely coil the excess and secure using suitable clamps. • During the diaphragm seal installation, ensure as far as possible that no seal liquid head is applied to the diaphragm seals. • Exercise care so as not to damage diaphragm surfaces. Since the diaphragm protrudes approx. 1mm from the flange surface, placing the diaphragm seals with their diaphragm surfaces facing downward may damage the diaphragm surfaces. • Do not sharply bend or twist capillary tube or apply excessive stress to them. IMPORTANT • When welding piping during construction, take care not to allow welding currents to flow through the transmitter. • Do not step on this instrument after installation. 4.2 Mounting the Diaphragm Seals Mount the diaphragm seals using the flanges as shown in Figure 4.2.1. Figure 4.2.2 shows how to mount the diaphragm seals on a tank. The customer should prepare the mating flange, gasket, bolts and nuts. Flange Bolt Nut Diaphragm ød Gasket IMPORTANT The product is shipped with these parts assembled. Correctly install the diaphragm seals on the high and low pressure sides of the process, checking the label on each seal.

WIRING 5. WIRING 5.1 Wiring Precautions CAUTION If the transmitter is flameproof and the ambient temperature is 50°C or more, use cables having a maximum allowable heat resistance of at least 75°C in consideration of the instrument's generation of heat or the cables' self-heating. IMPORTANT • Lay wiring as far as possible from electrical noise sources such as large capacity transformers, motors, and power supplies. • Remove 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. • Explosion-protected instruments must be wired in accordance with specific requirements (and, in certain countries, legal regulations) in order to preserve the effectiveness of their explosionprotected features. • The terminal box cover is locked by an Allen head bolt (a shrouding bolt) on CENELEC, SAA, and JIS flameproof type transmitters. When the shrouding bolt is driven clockwise by an Allen wrench, it is going in and cover lock is released, and then the cover can be opened. See Subsection 8.4 “Disassembly and Reassembly” for details. Refer to The “Installation and Operating Precautions for JIS Flameproof Equipment” and “Installation and Operating Precautions for JIS Intrinsically Safe Equipment” at the end of this manual for correct wiring. (d) In environment where oils, solvents, corrosive gases or liquids may be present, use wires or cables that are resistant to such substances. (e) It is recommended that crimp-on solderless terminal lugs (for 4 mm screws) with insulating sleeves be used for leadwire ends. 5.3 Connections of External Wiring to Terminal Box 5.3.1 Power Supply Wiring Connection Connect the power supply wiring to the SUPPLY + and – terminals.

There will be cases in which the output signal exhibits wide fluctuations (hunting) due to periodic variation in the process pressure. In such cases, BT200 operation can dampen the transmitter output signal. Confirm the hunting using a receiving instrument or the integral indicator, and set the optimum damping time constant. See Subsection 7.3.3 (3), “Damping Time Constant Setup.” 2) After confirming the operating status, perform the following. ESC IMPORTANT • Remove the BT200 from the terminal box, and confirm that none of the terminal screws are loosened. • Close the terminal box cover and the amplifier cover. Screw each cover in tightly until it will not turn further. • Two covers are required to be locked on the CENELEC, SAA, and JIS Flameproof type transmitters. An Allen head bolts (shrouding bolts) are provided under edge of the each cover for locking. When a shrouding bolts are driven counterclockwise by an Allen wrench, it is coming out and locks up a cover. (See page 8-4) After locking, the covers shoud be confirmed not to be opened. • Tighten the zero-adjustment cover mounting screw to fix the cover in position. Change setting to the actually SET J10:ZERO ADJ –0.0 % + 040.0 measured value (40.0%). Press key twice for 40% output 10.4 mA DC. CLR ESC F0606.EPS 6.4 Shutting Down Operation Turn off the power. NOTE Whenever shutting down the transmitter for a long period, detach the transmitter (diaphragm seals) from the tank. 6-3 IM 1C22H1-01E 6. OPERATION 6.5 Setting the Range Using the Range-setting Switch IMPORTANT • Do not turn off the power to the transmitter immediately after completion of the change in the LRV (and/or HRV) setting(s). Note that powering off within thirty seconds after setting will cause a return to the previous settings. • Changing LRV a utomatically changes HRV to the following value. With actual pressure being applied to the transmitter, the range-setting switch (push-button) located on the optional integral indicator plate and the external zeroadjustment screw allow users to change (re-range) the low- and high-limit values for the measurement range (LRV and HRV) without using BT200. However, other changes in the display settings (scale range and engineering unit) for the integral indicator requires BT200. HRV = previous HRV + (new LRV – previous LRV) • If the range-setting push-button and external zero-adjustment screw are not touched during a range-change operation, the transmitter automatically switches back to the normal operation mode. Follow the procedure below to change the LRV and HRV settings. [Example] Rerange LRV to 0 and HRV to 3 MPa. 1) Connect the transmitter and apparatus as shown in Figure 8.3.1 and warm up for at least five minutes. 2) Press the range-setting push-button. The integral indicator then displays “LSET.” 3) Apply a pressure of 0 kPa (atmospheric pressure) to the transmitter. (Note 1) 4) Turn the external zero-adjustment screw in the desired direction. The integral indicator displays the output signal in %. (Note 2) 5) Adjust the output signal to 0% (1 V DC) by rotating the external zero-adjustment screw. Doing so completes the LRV setting. 6) Press the range-setting push-button. The integral indicator then displays “HSET.” 7) Apply a pressure of 3 MPa to the transmitter. (Note 1) 8) Turn the external zero-adjustment screw in the desired direction. The integral indicator displays the output signal in %.

BRAIN TERMINAL BT200 OPERATION 7.3.2 Parameter Usage and Selection IMPORTANT Before describing the procedure for setting parameters, we present the following table showing how the parameters are used and in what case. If the transmitter is turned off within 30 seconds after parameters have been set, the set data will not be stored and the terminal returns to previous settings. Table 7.3.1 Parameter Usage and Selection Setup Item Tag No. setup c P.7-7 Calibration range setup c P.7-7 Description Sets the Tag No. (using 16 alphanumeric characters). Note: Up to 8 alphanumerics (upper case letters) can be used in the BT100. Sets the calibration range for 4 to 20 mA DC. Sets three data items: range unit, input value at 4 mA DC (LRV), and input value at 20 mA DC (HRV). Note: LRV and HRV can be specified with range value specifications up to 5 digits (excluding any decimal point) within the range of –32000 to 32000. Damping time constant setup c P.7-8 Output and integral indicator display mode setup c P.7-9 Adjusts the output response speed for 4 to 20 mA DC. Can be set in 9 increments from 0.2 to 64 s. Sets modes for output signal and integral indicator to “Linear mode” (proportional to input differential pressure) or to “Square root mode” (proportional to flow). Output signal low cut mode setup c P.7-9 Used mainly to stabilize output near 0% if output signal is the square root mode. Two modes are available: forcing output to 0% for input below a specific value, or changing to proportional output for input below a specific value. Integral indicator scale range and unit setup c P.7-10 Sets the following 5 types of integral indicator scale ranges and units: % scale indicator, user set scale indicator, alternate indication of user set scale and % scale, input pressure display, alternate indication of input pressure and % scale When using the user set scale, 4 types of data can be set: user set scale setting, unit (BT200 only), display value at 4 mA DC (LRV), and display value at 20 mA DC (HRV). Note: LRV and HRV can be specified with range value specifications up to 5 digits (excluding any decimal point) within the range of –19999 to 19999. Unit setup for displayed temperature c P.7-11 Sets a unit for temperatures displayed on the BT200. Unit setup for displayed static pressure c P.7-11 Sets a unit for static pressure displayed on the BT200. Operation mode (normal/reverse signal) setup c P.7-12 Reverses the direction for 4 to 20 mA DC output relative to input. Reverse mode is used for applications in which safety requires that output be driven toward 20 mA if input is lost. Impulse line connection orientation (higher pressure on right/left side) setup c P.7-12 Used where installation conditions make it imperative to connect high pressure side impulse line to low pressure side of transmitter. Reversal of orientation should be dealt with by reversing impulse line wherever possible. Use this function only where there is no alternative. Output status display/setup when a CPU failure c P.7-12 Displays the status of 4 to 20 mA DC output when a CPU failure. The parameter of the standard unit is fixed to the high limit value. Output status setup when a hardware Sets the status of the 4 to 20 mA DC output when an abnormal status is detected error occurs with the capsule or the amplifier as the result of self-diagnosis. One of the c P.7-12 following statuses; last held, high limit, and low limit values, can be selected. Bi-directional flow measurement c P.7-13 Used to measure bi-directional flows. Output at zero flow is 12 mA DC, with output range equally divided between forward and reverse flow. Can be used with square root mode. Range change (while applying actual inputs) c P.7-13 Range for 4 to 20 mA DC signal is set with actual input applied. Sets 20 mA DC output precisely with respect to user’s reference instrument output. Note that DPharp is calibrated with high accuracy before shipment, so span should be set using the normal range setup. Zero point adjustment c P.7-14 Adjusts zero point. This can be done either using the external zero-adjustment screw on the transmitteror using the BT200. Test output (fixed current output) setup c P.7-15 Used for loop checks. Output can be set freely from –5% to 110% in 1% steps. User memo fields c P.7-15 Allows user to enter up to 5 items of any desired text in up to 8 uppercase alphanumeric characters per item.

MAINTENANCE 8.1 Overview WARNING Since the accumulated process fluid may be toxic or otherwise harmful, take appropriate care to avoid contact with the body, or inhalation of vapors during draining condensate or venting gas in transmitter pressure-detector section even after dismounting the instrument from process line for maintenance. Maintenance of the transmitter is easy due to its modular construction. This chapter describes the procedures for calibration, adjustment, and the disassembly and reassembly procedures required for component replacement. 8.2 Calibration Instruments Selection Table 8.2.1 shows the instruments required for calibration. Select instruments that will enable the transmitter to be calibrated or adjusted to the required accuracy. The calibration instruments should be handled carefully so as to maintain the specified accuracy. 8.3 Calibration Use the procedure below to check instrument operation and accuracy during periodic maintenance or troubleshooting. 1) Connect the instruments as shown in Figure 8.3.1 and warm up the instruments for at least five minutes. Since the transmitters are precision instruments, carefully and thoroughly read the following sections for proper handling during maintenance. IMPORTANT • To adjust the transmitter for highest accuracy, make adjustments with the power supply voltage and load resistance including leadwire resistances set close to the conditions under which the transmitter is installed. • If the measurement range 0% point is 0 kPa or shifted in the positive direction (suppressed zero), the reference pressure should be applied on the high pressure side, as shown in the figure (low pressure side open to atmosphere). If the measurement range 0% point is shifted in the negative direction (elevated zero), the reference pressure should be applied on the low pressure side. IMPORTANT • As a rule, maintenance of this transmitter should be implemented in a maintenance service shop where the necessary tools are provided. • The CPU assembly contains sensitive parts that may be damaged by static electricity. Exercise care so as not to directly touch the electronic parts or circuit patterns on the board, for example, by preventing static electrification by using grounded wrist straps when handling the assembly. Also take precautions such as placing a removed CPU assembly into a bag with an antistatic coating. 2) Apply reference pressures of 0%, 50%, and 100% of the measurement range to the transmitter. Calculate the errors (differences between digital voltmeter readings and reference pressures) as the pressure is increased from 0% to 100% and is decreased from 100% to 0%, and confirm that the errors are within the required accuracy. Note: When the output mode is set to SQRT, apply reference pressures of 0, 6.25, 25, 56.25 and 100%, instead. 8-1 IM 1C22H1-01E 8.

Confirm that the zero-adjustment screw pin is placed properly in the groove on the bracket prior to tightening the two bosses. If it is not, the zero-adjustment mechanism will be damaged. 5) Replace the cover. NOTE Be careful not to apply excessive force to the CPU assembly when removing it. j Mounting the CPU Assembly 1) Connect the flat cable (with black connector) between the CPU assembly and the capsule. 2) Connect the output terminal cable (with brown connector). NOTE Make certain that the cables are free of pinching between the case and the CPU assembly edge. 3) Align and engage the zero-adjustment screw pin with the groove on the bracket on the CPU assembly. Then insert the CPU board assembly straight onto the post in the amplifier case. 4) Tighten the two bosses. If the transmitter is equipped with an integral indicator, refer to Subsection 8.4.1 to mount the indicator. 8-4 IM 1C22H1-01E 8. MAINTENANCE 8.5 Troubleshooting 8.5.2 Troubleshooting Flow Charts If any abnormality appears in the measured values, use the troubleshooting flow chart below to isolate and remedy the problem. Since some problems have complex causes, these flow charts may not identify all. If you have difficulty isolating or correcting a problem, contact Yokogawa service personnel. The following sorts of symptoms indicate that transmitter may not be operating properly. Example : • There is no output signal. • Output signal does not change even though process variable is known to be varying. • Output value is inconsistent with value inferred for process variable. 8.5.1 Basic Troubleshooting Connect BRAIN TERMINAL and check self-diagnostics.

These tests are required to satisfy either the technical criteria for electrical machinery and equipment in compliance with explosionproof standards involving inflammable gases or vapors and for machinery and equipment having explosionproof performance (standards notification no. 556 from the Japanese Ministry of Labor) (hereinafter referred to as technical criteria), in conformity with IEC Standards, or the “Recommended Practice for Explosion-Protected Electrical Installations in General Industries,” published in 1979. Such a certified apparatus can be used in hazardous locations where inflammable gases or vapors may be present. The intrinsic safety type of explosion-protected construction is a method of protection applicable to a circuit or part of a circuit in which, under prescribed test conditions, no spark or thermal effect, whether produced normally or accidentally, is capable of causing a prescribed explosive gas to ignite. In other words, electrical apparatus of this construction is intended to suppress electrical energy thereby preventing ignition of a given explosive gas atmosphere even though spark or high thermal effect occurs in the electric circuitry. Intrinsically safe electrical apparatus generally comprise intrinsically safe apparatus installed in a hazardous location and a safety barrier (associated apparatus), installed in a nonhazardous location, aimed at preventing electrical energy from flowing into the electric circuitry of intrinsically safe apparatus. Certified apparatus includes a certification label and an equipment nameplate with the specifications necessary for explosion requirements as well as precautions on explosion protection. Please confirm these precautionary items and use them to meet specification requirements. However, battery-operated, portable intrinsically safe apparatus or the like may be used alone. For electrical wiring and maintenance servicing, please refer to “Internal Wiring Rules” in the Electrical Installation Technical Standards as well as “USER’S GUIDELINES for Electrical Installations for Explosive Gas Atmospheres in General Industry,” published in 1994. 3. Terminology (1) Intrinsically safe apparatus: Electrical apparatus in which all the circuits are intrinsically safe circuits. (2) Associated apparatus: Electrical apparatus in which there are both intrinsically safe circuits and non-intrinsically safe circuits that can affect the safety of intrinsically safe circuits. (3) Safety barrier: A specific type of associated apparatus, which consists mainly of safety barrier elements, and serves to limit the flow of excessive electrical energy, which is capable of causing ignition of a given explosive gas or vapour of a non-intrinsically safe circuit into concerned intrinsically safe circuits. (4) Apparatus of category “ia”: Intrinsically safe electrical apparatus and associated apparatus which are incapable of causing ignition of a given explosive gas or vapour with the appropriate safety factors such as: To meet intrinsically safe requirements, equipment that can be termed an “intrinsically safe apparatus” must: (1) be certified by the Technical Institute of Industrial Safety, Inc. in accordance with the Labor Safety and Health Laws of Japan and have the appropriate mark of certification labeled on its case, and (2) be used in compliance with the specifications marked on its certification label, equipment nameplate and precautionary information furnished. Note: Intrinsically safe apparatus satisfy their performance under specific conditions. They are not always absolutely safe under every operational and environmental condition. In other 1 EX-A03E INSTALLATION AND OPERATING PRECAUTIONS FOR JIS INTRINSICALLY SAFE EQUIPMENT (2) For pressure transmitters, pH transmitters, temperature detectors and the like, safety barriers that can be combined are already specified. Other safety barriers cannot be used. — when up to two countable faults are applied and, in addition, — when non-countable faults produce an onerous condition. (5) Apparatus of category “ib”: Intrinsically safe electrical apparatus and associated apparatus which are incapable of causing ignition of a given explosive gas or vapour, with the appropriate safety factors such as: — when up to one countable fault is applied and, in addition, — when non-countable faults produce an onerous condition. (6) Safety rating: A rating to be designated to intrinsically safe apparatus as well as associated apparatus and is the maximum rating allowable for maintaining intrinsic safety of concerned intrinsically safe circuits. Note 2: Testing Intrinsically Safe System An assembly (as a system) in which intrinsically safe apparatus and safety barriers are combined is assessed to ensure that its safety requirements are satisfied. A tested and certified system incorporates a certification number (intrinsically safe apparatus and safety barriers have the same certification number). Note 3: Impossible Combinations of Apparatus Certified Under Different Standards Intrinsically safe apparatus certified under technical criteria and safety barriers certified under the “Recommended Practice for Explosion-Protected Electrical Installations in General Industries” (1979) and vice versa cannot be combined even if their combination requirements are satisfied. 4. Caution on Combining Intrinsically Safe Apparatus and Safety Barriers 5. Installation of Intrinsically Safe Apparatus and Safety Barriers (1) Classification of installation location (1) A combination of certified intrinsically safe apparatus and safety barriers needs to satisfy combination requirements. If intrinsically safe apparatus specify safety barriers for combination, safety barriers other than specified cannot be used (see Note 1 for more details). (2) Certified intrinsically safe systems specify specific safety barriers in combination with intrinsically safe apparatus. So safety barriers other than specified cannot be used (see Note 2 for more details). (3) Other than limitations of combining intrinsically safe apparatus and safety barriers as given in (1) and (2) above, two or more pieces of apparatus certified under different standards cannot be combined with each other (see Note 3 for more details). In addition, bear in mind that classifications of explosion protection such as “IIA,” “IIB” and “IIC” and category “ia” and “ib” limit a combination of intrinsically safe apparatus and safety barriers. For more details, see the “Type Certificate Guide for Explosion-Protected Constructionfor Electrical Machinery and Equipment,” issued by the Japanese Ministry of Labour, the Research Institute of Industrial Safety. Intrinsically safe apparatus may be installed, depending upon applicable gases, in a hazardous area in Zone 0, 1 or 2 (Note 4 below), where the specified gases are present. However, note that apparatus certified under Technical Criteria, in category “ib” shall be installed only in Zone 1 or 2. Safety barriers (associated apparatus) that are combined with these intrinsically safe apparatus shall be installed only in a nonhazardous area. In cases where safety barriers are installed in a hazardous area, they shall be enclosed, for example, in a flameproof enclosure. Note 4: Hazardous areas are classified in zones based upon the frequency of the appearance and the duration of an explosive gas atmosphere as follows: Zone 0: An area in which an explosive gas atmosphere is present continuously or is present for long periods. Zone 1: An area in which an explosive gas atmosphere is likely to occur in normal operation. Zone 2: An area in which an explosive gas atmosphere is not likely to occur in normal operation and if it does occur it will exist for a short period only. (2) Ambient temperature limits for intrinsically safe apparatus Intrinsically safe apparatus shall be installed in a location where the ambient temperature ranges from –20° to +40°C (for those certified under Technical Criteria) or –10° to +40°C (for those certified under the “Recommended Practice for Explosion-Protected Electrical Installations in General Industries” (1979). However, some field-mounted Note 1: Testing Apparatus Intrinsically safe apparatus and safety barriers are assessed individually to ensure that their safety requirements are satisfied. Tested and certified intrinsically safe apparatus and safety barriers incorporate individual certification numbers. A combination of intrinsically safe apparatus and safety barriers involves the following two limitations: (1) A safety barrier which meets the combination requirements by referring to its safety rating and combination parameters shall be selected. 2 EX-A03E INSTALLATION AND OPERATING PRECAUTIONS FOR JIS INTRINSICALLY SAFE EQUIPMENT intrinsically safe apparatus may be used at an ambient temperature up to 60°C. So, specifications should be checked before installing intrinsically safe apparatus. Installations for Explosive Gas Atmospheres in General Industry” issued in 1994 by the Japanese Ministry of Labour, the Research Institute of Industrial Safety. If the intrinsically safe apparatus are exposed to direct sunshine or radiant heat from plant facilities, appropriate thermal protection measures shall be taken. (1) Requirements for maintenance personnel Maintenance and inspection of intrinsically safe apparatus and safety barriers shall be conducted by maintenance personnel skilled in intrinsically safe construction and installation of electrical devices as well as capable of applying associated rules. 6. Wiring for Intrinsically Safe Circuits In intrinsically safe construction, safety shall be maintained as an intrinsically safe system involving intrinsically safe apparatus and safety barriers connected thereto, and electrical wiring (through intrinsically safe circuits) interconnected between them. In other words, even when safety requirements are maintained individually by intrinsically safe apparatus and safety barriers, they shall not be affected by electrical or magnetic energy caused by electrical wiring. (2) Maintenance and Inspection (a) Visual inspection Visually inspect the external connections of intrinsically safe apparatus and safety barriers, and cables for damage or corrosion as well as other mechanical and structural defects. (b) Adjustments Zero, span and sensitivity adjustments shall be made with applicable adjusting potentiometers and mechanical adjustment screws. These maintenance adjustments shall be made in a nonhazardous location. To make electrical wiring for intrinsically safe circuits, you must: (a) refer to the equipment configuration diagram and make electrical wiring properly; (b) prevent intrinsically safe wiring from being contacted with non-intrinsically safe wiring, and separate the intrinsically safe circuit from other electrical circuits; (c) prevent intrinsically safe wiring from being electrostatically and magnetically affected by nonintrinsically safe wiring; (d) reduce wiring inductance and capacitance produced between the intrinsically safe apparatus and safety barrier where possible, and use a shorter cable between the intrinsically safe apparatus and safety barrier than specified if the maximum permissible inductance of the cable is specified as operating conditions; (e) conform to conditions of installation such as wiring method, earthing or the like, if any; and (f) protect the outer sheath of cables from damage with appropriate measures. CAUTION If intrinsically safe apparatus and safety barriers require maintenance service and checking, a gas detector shall be used to ensure that there is no explosive gas in the location (maintenance servicing shall be conducted in a nonhazardous location). (3) Repair Intrinsically safe apparatus and safety barriers shall be repaired by manufacturers. (4) Prohibition of modifications and specification changes Do not attempt to make modifications or change specifications which may affect safety. 7. Maintenance and Inspection of Intrinsically Safe Apparatus and Safety Barriers Maintenance and inspection of intrinsically safe apparatus and safety barriers shall be limited to within the instructions described in applicable instruction manuals. If other than this is required, contact the manufacturers. For more information, refer to the “USER’S GUIDELINES for Electrical 3 EX-A03E INSTALLATION AND OPERATING PRECAUTIONS FOR JIS FLAMEPROOF EQUIPMENT INSTALLATION AND OPERATING PRECAUTIONS FOR JIS FLAMEPROOF EQUIPMENT Apparatus Certified Under Technical Criteria (IEC-compatible Standards) 1. General construction is of completely enclosed type and its enclosure shall endure explosive pressures in cases where explosive gases or vapours entering the enclosure cause explosion. In addition, the enclosure construction shall be such that flame caused by explosion does not ignite gases or vapours outside the enclosure. The following describes precautions on electrical apparatus of flameproof construction (hereinafter referred to as flameproof apparatus) in explosion-protected apparatus. Following the Labour Safety and Health Laws of Japan, flameproof apparatus is subjected to type tests to meet either the technical criteria for explosionproof electrical machinery and equipment (standards notification no. 556 from the Japanese Ministry of Labour) (hereinafter referred to as technical criteria), in conformity with the IEC Standards, or the “Recommended Practice for Explosion-Protected Electrical Installations in General Industries,” published in 1979. These certified apparatus can be used in hazardous locations where explosive or inflammable gases or vapours may be present. In this manual, the word "flameproof" is applied to the flameproof equipment combined with the types of protection "e", "o", "i", and "d" as well as flameproof equipment. 3. Terminology (1) Enclosure An outer shell of an electrical apparatus, which encloses live parts and thus is needed to configure explosion-protected construction. Certified apparatus includes a certification label and an equipment nameplate with the specifications necessary for explosion requirements as well as precautions on explosion protection. Please confirm these precautionary items and use them to meet specification requirements. (2) Shroud A component part which is so designed that the fastening of joint surfaces cannot be loosened unless a special tool is used. For electrical wiring and maintenance servicing, please refer to “Internal Wiring Rules” in the Electrical Installation Technical Standards as well as “USER’S GUIDELINES for Electrical Installations for Explosive Gas Atmospheres in General Industry,” published in 1994. (3) Enclosure internal volume This is indicated by:— the total internal volume of the flameproof enclosure minus the volume of the internal components essential to equipment functions. To meet flameproof requirements, equipment that can be termed “flameproof” must: (4) Path length of joint surface On a joint surface, the length of the shortest path through which flame flows from the inside to outside of the flameproof enclosure. This definition cannot be applied to threaded joints. (1) Be certified by a Japanese public authority in accordance with the Labour Safety and Health Laws of Japan and have a certification label in an appropriate location on its case, and (2) Be used in compliance with the specifications marked on its certification label, equipment nameplate and precautionary information furnished. (5) Gaps between joint surfaces The physical distance between two mating surfaces, or differences in diameters if the mating surfaces are cylindrical. 2. Electrical Apparatus of Flameproof Type of ExplosionProtected Construction Note: The permissible sizes of gaps between joint surfaces, the path length of a joint surface and the number of joint threads are determined by such factors as the enclosure’s internal volume, joint and mating surface construction, and the explosion classification of the specified gases and vapours. Electrical apparatus which is of flameproof construction is subjected to a type test and certified by the Japanese Ministry of Labour aiming at preventing explosion caused by electrical apparatus in a factory or any location where inflammable gases or vapours may be present. The flameproof 1 EX-B03E INSTALLATION AND OPERATING PRECAUTIONS FOR JIS FLAMEPROOF EQUIPMENT 4. Installation of Flameproof Apparatus • Specific cables shall be used as recommended by the “USER’S GUIDELINES for Electrical Installations for Explosive Gas Atmospheres in General Industry,” published in 1994. • In necessary, appropriate protective pipes (conduit or flexible pipes), ducts or trays shall be used for preventing the cable run (outside the cable glands) from damage. • To prevent explosive atmosphere from being propagated form Zone 1 or 2 hazardous location to any different location or non-hazardous location through the protective pipe or duct, apply sealing of the protective pipes in the vicinity of individual boundaries, or fill the ducts with sand appropriately. • When branch connections of cables, or cable connections with insulated cables inside the conduit pipes are made, a flameproof or increased-safety connection box shall be used. In this case, flameproof or increased-safety cable glands meeting the type of connection box must be used for cable connections to the box. (1) Installation Area Flameproof apparatus may be installed, in accordance with applicable gases, in a hazardous area in Zone 1 or 2, where the specified gases are present. Those apparatus shall not be installed in a hazardous area in Zone 0. Note: Hazardous areas are classified in zones based upon the frequency of the appearance and the duration of an explosive gas atmosphere as follows: Zone 0: An area in which an explosive gas atmosphere is present continuously or is present for long periods. Zone 1: An area in which an explosive gas atmosphere is likely to occur in normal operation. Zone 2: An area in which an explosive gas atmosphere is not likely to occur in normal operation and if it does occur it will exist for a short period only. (2) Environmental Conditions The standard environmental condition for the installation of flameproof apparatus is limited to an ambient temperature range from –20°C to +40°C (for products certified under Technical Criteria). However, some field-mounted instruments may be certified at an ambient temperature up to +60°C as indicated on the instrument nameplates. If the flameproof apparatus are exposed to direct sunshine or radiant heat from plant facilities, appropriate thermal protection measures shall be taken. (2) Flameproof Metal Conduit Wiring • For the flameproof metal conduit wiring or insulated wires shall be used as recommended by the USER’S GUIDELINES for Electrical Installations for Explosive Gas Atmospheres in General Industry, published in 1994. • For conduit pipes, heavy-gauge steel conduits conforming to JIS C 8305 Standard shall be used. • Flameproof sealing fittings shall be used in the vicinity of the wiring connections, and those fittings shall be filled with sealing compounds to complete sealing of the apparatus. In addition, to prevent explosive gases, moisture, or flame caused by explosion form being propagated through the conduit, always provide sealing fittings to complete sealing of the conduit in the following locations: (a) In the boundaries between the hazardous and nonhazardous locations. (b) In the boundaries where there is a different classification of hazardous location. • For the connections of the apparatus with a conduit pipe or its associated accessories, G-type parallel pipe threads (JIS B 0202) shall be used to provide a minimum of five-thread engagement to complete tightness. In addition, since these parallel threads do not have sealing property, nonhardening sealant such as liquid gaskets shall thus be applied to those threads for ensuring waterproofness. • If metal conduits need flexibility, use flameproof flexible fittings. 5. External Wiring for Flameproof Apparatus Flameproof apparatus require cable wiring or flameproof metal conduits for their electrical connections. For cable wiring, cable glands (cable entry devices for flameproof type) to wiring connections shall be attached. For metal conduits, attach sealing fittings as close to wiring connections as possible and completely seal the apparatus. All non-live metal parts such as the enclosure shall be securely grounded. For details, see the “USER’S GUIDELINES for Electrical Installations for Explosive Gas Atmospheres in General Industry,” published in 1994. (1) Cable Wiring • For cable wiring, cable glands (cable entry devices for flameproof type) specified or supplied with the apparatus shall be directly attached to the wiring connections to complete sealing of the apparatus. • Screws that connect cable glands to the apparatus are those for G-type parallel pipe threads (JIS B 0202) with no sealing property. To protect the apparatus from corrosive gases or moisture, apply nonhardening sealant such as liquid gaskets to those threads for waterproofing. 2 EX-B03E INSTALLATION AND OPERATING PRECAUTIONS FOR JIS FLAMEPROOF EQUIPMENT 6. Maintenance of Flameproof Apparatus requirements for flameproof apparatus (however, bear in mind that the apparatus must always be restored to its original condition). If you attempt to repair the flameproof apparatus, company-specified components shall be used. (d) Before starting to service the apparatus, be sure to check all parts necessary for retaining the requirements for flameproof apparatus. For this, check that all screws, bolts, nuts, and threaded connections have properly been tightened. To maintain the flameproof apparatus, do the following. (For details, see Chapter 10 “MAINTENANCE OF EXPLOSIONPROTECTED ELECTRICAL INSTALLATION” in the USER’S GUIDELINES for Electrical Installations for Explosive Gas Atmospheres in General Industry.) (1) Maintenance servicing with the power on. Flameproof apparatus shall not be maintenance-serviced with its power turned on. However, in cases where maintenance servicing is to be conducted with the power turned on, with the equipment cover removed, always use a gas detector to check that there is no explosive gas in that location. If it cannot be checked whether an explosive gas is present or not, maintenance servicing shall be limited to the following two items: (3) Prohibition of specification changes and modifications Do not attempt to change specifications or make modifications involving addition of or changes in external wiring connections. 7. Selection of Cable Entry Devices for Flameproof Type (a) Visual inspection Visually inspect the flameproof apparatus, metal conduits, and cables for damage or corrosion, and other mechanical and structural defects. (b) Zero and span adjustments These adjustments should be made only to the extent that they can be conducted from the outside without opening the equipment cover. In doing this, great care must be taken not to cause mechanical sparks with tools. IMPORTANT The cable glands (cable entry devices for flameproof type) conforming to IEC Standards are certified in combination with the flameproof apparatus. So, Yokogawa-specified cable entry devices for flameproof type shall be used to meet this demand. (2) Repair If the flameproof apparatus requires repair, turn off the power and transport it to a safety (non-hazardous) location. Observe the following points before attempting to repair the apparatus. References: (1) Type Certificate Guide for Explosion-Protected Construction Electrical Machinery and Equipment (relating to Technical Standards Conforming to International Standards), issued by the Technical Institution of Industrial Safety, Japan (2) USER’S GUIDELINES for Electrical Installations for Explosive Gas Atmospheres in General Industry (1994), issued by the Japanese Ministry of Labour, the Research Institute of Industrial Safet (a) Make only such electrical and mechanical repairs as will restore the apparatus to its original condition. For the flameproof apparatus, the gaps and path lengths of joints and mating surfaces, and mechanical strength of enclosures are critical factors in explosion protection. Exercise great care not to damage the joints or shock the enclosure. (b) If any damage occurs in threads, joints or mating surfaces, inspection windows, connections between the transmitter and terminal box, shrouds or clamps, or external wiring connections which are essential in flameproofness, contact Yokogawa Electric Corporation. CAUTION Do not attempt to re-process threaded connections or refinish joints or mating surfaces.
