PREFACE

DANGERDANGER
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 PH202 transmitter.
Notice
• This manual should be passed on to the end user.
• The contents of this manual are subject to change without prior notice.
• The contents of this manual shall not be reproduced or copied, in part or in whole, without permission.
• This manual explains the functions contained in this product, but does not warrant that they are suitable the particular purpose of the user.

However, when you realize mistaken
expressions or omissions, please contact the nearest Yokogawa Electric representative or sales office.
• This manual does not cover the special specifications. This manual may be left unchanged on any change of specification, construction or parts when the change does not affect the functions or performance of the product.
• If the product is not used in a manner specified in this manual, the safety of this product may be impaired.
Yokogawa is not responsible for damage to the instrument, poor performance of the instrument or losses resulting from such, if the problems are caused by:

• Use of the instrument in improper applications
• Use of the instrument in an improper environment or improper utility program
• Repair or modification of the related instrument by an engineer not authorized by Yokogawa.
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.
Warning label
Because the enclosure of the pH/ORP transmitter Type PH202S-E, -P, -F are made of aluminium, if it is mounted in an area where the use of category 1 G Zone 0 apparatus is required, it must be installed such, that, even in the event of rare inci­dents, ignition sources due to impact and friction sparks are excluded.

1-2. Application

The EXA converter is intended to be used for continuous on-line measurement in industrial installations. The unit combines simple operation and microprocessor-based performance with advanced self-diag­nostics 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/neutralization system.
Yokogawa designed the EXA analyzer to withstand harsh environments. The converter 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 con­verter in order to ensure easy calibration and peak performance. If the unit must be mounted remotely from the sensors, WF10 extension cable can be used up to a maximum of 50 metres (150 feet) with a BA10 junction box. Except installations with dual high impedance sensors, where the maximum cable length is 20 metres using integral cable only (no junction box).
The EXA is delivered with a general purpose default setting for programmable items. (Default settings are listed in Chapter 5 and again in Chapter 10). 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 eight different types of temperature sensors.
To record such configuration adjustments, write changes in the space provided in Chapter 10 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.

14 AWG) Cable entry: 2 cable glands 1/2NPT. The cable glands will form a tight seal on cables with an outside diameter in the range of 6 to 12 mm (0.24 to 0.47 inches). Construction : Weather resistant to IP65 and NEMA 4X standards Mounting : Pipe, wall or panel mounting, using optional hardware Weight : Approx. 1.6 kg
G. Shipping details
: Package size w x h x d
290 x 300 x 290 mm.
11.5 x 11.8 x 11.5 in. Packed weight approx. 2.5 kg (5lb)
H. Data protection
: EEPROM for configuration and logbook, and
lithium cell for clock.
I. Watchdog timer
: Checks microprocessor
J. Automatic safeguard
: Return to measuring mode when no keystroke
is made for 10 min.
K. Operation protection
: 3-digit programmable password.
L. Sensor impedance checking
: Independent impedance check on measuring
and reference sensor elements, with temperature compensation. Display of sensor impedance on message line of display. FAIL flag in event of “out of limits” impedance, and the possibility of 21 mA or (3.6 mA or 3.9 mA) error signal.
M. Signal processing (pH/ORP)
: The PH202 can measure pH or ORP. Using
the FU20 allows simultaneous measurement and display of pH and ORP. It also allows display and out put of pH.

x In case of using cable glands in Outdoor location, they shall be UV rated or made of metal.
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 5 nF and 10 H respectively.
IM 12B07D02-01E
Specification 2-17
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
