PREFACE

DANGER
Electric discharge
The EXA analyzer contains devices that can be damaged by electrostatic discharge. When servicing this equipment, please observe proper procedures to prevent such damage. Replacement components should be shipped in conductive packaging. Repair work should be done at grounded workstations using grounded soldering irons and wrist straps to avoid electrostatic discharge.
Installation and wiring
The EXA analyzer should only be used with equip­ment that meets the relevant international and regional standards. Yokogawa accepts no responsi­bility for the misuse of this unit.
CAUTIONCAUTION
The instrument is packed carefully with shock absorbing materials, nevertheless, the instrument may be damaged or broken if subjected to strong shock, such as if the instrument is dropped. Handle with care.
Although the instrument has a weatherproof construction, the transmitter can be harmed if it becomes submerged in water or becomes exces­sively wet.
Do not use an abrasive material or solvent when cleaning the instrument.
Do not modify the SC202 transmitter.
WARNING
WARNING
Electrostatic charge may cause an explosion haz­ard. Avoid any actions that cause the generation of electrostatic charge, e.g., rubbing with a dry cloth.

Introduction 1-3

1-2. Application

The EXA transmitter is intended to be used for continuous on-line measurement in industrial installa­tions. The unit combines simple operation and microprocessor-based performance with advanced self­diagnostics and enhanced communications capability to meet the most advanced requirements. The measurement can be used as part of an automated process control system. It can also be used to indi­cate dangerous limits of a process, to monitor product quality, or to function as a simple controller for a dosing/neutralisation system. Yokogawa designed the EXA analyzer to withstand harsh environments. The transmitter may be installed either indoors or outside because the IP65 (NEMA 4X) housing and cabling glands ensure the unit is adequately protected. The flexible polycarbonate window on the front door of the EXA allows pushbutton access to the keypad, thus preserving the water and dust protection of the unit even during routine maintenance operations. A variety of EXA hardware is optionally available to allow wall, pipe, or panel mounting. Selecting a proper installation site will permit ease of operation. Sensors should normally be mounted close to the transmitter in order to ensure easy calibration and peak performance. The EXA is delivered with a general purpose default setting for programmable items. (Default settings are listed in Chapter 5 and again in Chapter 11). While this initial configuration allows easy start-up, the configuration should be adjusted to suit each particular application. An example of an adjustable item is the type of temperature sensor used. The EXA can be adjusted for any one of five different types of tem­perature sensors. To record such configuration adjustments, write changes in the space provided in Chapter 11 of this manual. Because the EXA is suitable for use as a monitor, a controller or an alarm instrument, program configuration possibilities are numerous. Details provided in this user’s manual are sufficient to operate the EXA with all Yokogawa sensor sys­tems and a wide range of third-party commercially available probes. For best results, read this manual in conjunction with the corresponding sensor user’s manual.
Yokogawa designed and built the EXA to meet the CE regulatory standards. The unit meets or exceeds stringent requirements of EN61326 Class A without compromise, to assure the user of continued accu­rate performance in even the most demanding industrial installations.

x The FISCO concept allows the interconnection of several I.S. apparatus not specifically
examined in such combination. The criterion for such interconnection is that the voltage (Vmax), the current (Imax) and the power (Pi) which I.S. apparatus can receive and remain intrinsically safe, considering faults, must be equal to or greater that the voltage (Voc, Vt), the current (Ioc, It) and the power (Poc, Pt) which can be providede by the FM approved FISCO barrier. In addition, the maximum unprotected residual capacitance (Ci) and inductance (Li) of each apparatus (other than the terminator) connected to the Fieldbus must be less than or equal to 5nF and 10 H respectively.
2-16 Specifications
x In each I.S. Fieldbus segment only one active source, normally the FM Approved FISCO
barrier, is allowed to provide the necessary power for the Fieldbus system. All other equipment connected to the bus cable has to be passive (not providing energy to the system), except to a leakage current of 50A for each connected device. Seperately powered equipment needs a galvanic isolation to insure that the I.S. Fieldbus circuit remains passive.
x The cable used to interconnect the devices needs to comply with the following parameters:
Loop resistance R’: 15 … 150 /km; Inductance per unit length L’: 0,4 … 1 mH/km Capacitance per unit length C’: 80 … 200 nF/km (C’ = C’ line/line + 0,5 C’ line/screen if both line are floating) (C’ = C’ line/line + C’ line/screen if the screen is connected to one line) Length of spur cable: max. 30 m Length of trunk cable: max. 1 km Length of splice : max. 1 m
