CAUTION ON SAFETY

First of all, read this “Caution on safety” carefully, and then use the particle counter

in the correct way.

The following items are important for safe operation and must be fully observed. These safety precautions are ranked in 2 levels; “DANGER” and “CAUTION.”

If operation is incorrect, a dangerous situation may occur, resulting in death

DANGER

CAUTION

DANGER

or serious injury.

If operation is incorrect, a dangerous situation may occur, resulting in minor to medium injuries or only physical damage to equipment.

Caution on installation and transportation

(1) When the analyzer (receiver unit and transmitter unit) is installed on in-

cineration facility, make sure the facility has stopped completely. Installing in an operating facility may cause high temperature gas injection resulting in burn.

(2) This analyzer is not explosion-proof. Do not use it in an atmosphere of

explosive gas. This may result in serious accidents such as explosion, fire, etc.

CAUTION

(1) The analyzer should be installed in a place conforming with the installa-

tion requirements noted in this instruction manual, and where the weight of the analyzer can be endured. Otherwise, it may cause a tip-over, drop, electric shocks, fire or malfunction of the unit.

(2) Ask professional services or your dealer for installation, transportation,

reinstallation, and associated piping and wiring work. Improper installation may result in a falling accident, electric shock, or injury.

(3) Check the installation site once every 6 months to make sure that the in-

stallation surface is free of rattling. If the instrument is used under insecure installation conditions, a falling accident may occur.

(4) During installation, make sure that the inside of the unit is free from ca-

ble chips and other foreign objects. Otherwise, it may cause fire, failure or malfunction.

(5) For lifting the gas analyzer, be sure to wear protective gloves. Bare hands

may leave you prone to injury. If the temperature in the installation site is high, it is imperative to wear leather gloves to prevent burn.

(6) The analyzer is heavy. It should be transported carefully by two or more

persons if manually required. Otherwise, bodily harm may ensue.

(7) Do not look into the transmitter unit or direct the laser beam to the eyes

of people while the power is turned ON. Otherwise, the laser beam may damage cornea of the eye.

(8) The laser beam is the invisible infrared light. Do not watch the laser

beam directly or scattering light.

(9) Do not watch the laser beam directly with the optical measuring device.

Otherwise, it may cause serious damage to your eyes.

forming class D grounding work. Otherwise electric shock or malfunction may result.

(2) If the power supply voltage exceeds the rating, electric shock or damage

to the instrument may result. Be sure to use the instrument within the

specified rating range. (3) Be sure to turn off the power before performing wiring work. (4) Be sure to use a 600V-IV ground wire 2 mm or larger in diameter with

sufficient dielectric strength. (5) Select input/output wires of materials and diameter that satisfy the rating

of each device. If a wire which cannot endure the rating is used, electric

shock or fire may occur. (6) Fasten the input/output wires to the floor or wall, and use a wire protec-

tion device.

Caution on operation and use

(1) When handling the standard gas such as calibration gas, read the instruc-

tion manual of the standard gas carefully, and use the gas correctly. (2) When toxic fumes, corrosive gas or inert gas is used as calibration gas,

be sure that the position of the air ventilation or exhaust port is suitable.

Otherwise you may inhale exhaust gas. Furthermore, suffocation, brain

disorder, circulatory deficit, or contraction of the breathing system may

occur, resulting in death.

(1) Do not touch the switch with a wet hand. Otherwise it may cause electric

CAUTION

shock. (2) Do not operate the laser gas analyzer for a long time with its door left

open. Otherwise, dust, foreign matter, etc. may stick on internal walls,

thereby causing faults. (3) Do not touch the unit terminal block during operation. Otherwise, it may

cause electric shock or injury. (4) Before leaving unused for a long time or restarting after left at such a

status for an extended length of time, follow the directions of each in-

struction manual because they are different from normal starting or

shutdown. Otherwise, adequate performance will not be provided. Fur-

thermore, an accident or fault may be caused. (5) Do not allow water to go into the gas analyzer. Otherwise, electric shock

or fire in the instrument may be caused. (6) Do not smoke nor use a flame near the gas analyzer. Otherwise, it may

result in a fire.

cineration facility, make sure the facility has stopped completely. Installing on the operating facility may cause high temperature gas injection, resulting in burn.

(2) If the analyzer is installed or removed from the location higher than op-

erator’s height, set up a fence to keep someone from approaching under or near the unit. If the analyzer inadvertently falls off and hits someone, serious injuries may occur, resulting in death.

(1) Be careful not to drop the analyzer on your foot. Otherwise, it may cause

fracture of the bone.

(2) Do not touch the terminal block of each unit of the instrument carelessly

during operation. Otherwise, it may cause electric shock.

(3) Before working, take off a wrist watch, finger ring or the like metallic

accessories. And never touch the instrument with a wet hand to avoid electric shocks.

(4) If the fuse is blown, eliminate the cause, and then replace it with the one

of the same capacity and type as before. Otherwise, it may cause electric shock or accident.

(5) Do not wash or splash water on the switch or electrical parts inside the

device. Otherwise it may cause an electric shock, failure, or fire.

1. GENERAL

1.1 General

Cross-stack laser gas analyzer (ZSS) provides continuous measurement of HCl in-flue gas incineration, NH3 density of denitration equipment and heat treat furnace, and O within a short response time. The cross-stack configuration eliminates the need for transfer of the preparation measurement gas to the analyzer for proper measurement. Dust resistant construction enables installation upstream of bug filter units and the application for which injection volume of calcium hydroxide is controlled while measuring HCl concentration. The analyzer adopts near-infrared laser as light source. The measuring object of the analyzer is only one spectrum line from large numbers of absorption spectrum lines, and it measures concentration by controlling temperature and power current. Since the range of wavelengths to be measured is a few nano meters, the analyzer has minimum interference by other crossovers. For the concentration detection, the modulated intensity of signal amplitude is employed instead of the amount of change of light.

1.2 Handling of product and operating precautions

, CO, and CO2 density for combustion control

First read this instruction manual carefully, and then make a plan for periodic inspection to perform appropriate maintenance management. To maintain the long-term performance of the cross-stack laser gas analyzer (ZSS), our periodic inspection contract is recommended. This analyzer uses the invisible infrared laser (excluding O optical measuring device included) or scattering light.

4.3 Mounting range of companion flange (in factory range)

Mount the companion flange so that it satisfies the conditions of the following figure (Fig. 4－2). If the conditions below are not satisfied, light cannot be received even if the light axis adjustment is performed by the

angle adjustment unit. In such a case, mount the companion flange again.

When θ (angle determined by laser light source and flange diameter) is bigger than 5°, mount the companion flange within the γ angle (≈5°) inside the circle with A radius. When the distance between laser light source and stack is long, or θ angle is less than 5° because flange diameter is small, both A radius and γ angle will become smaller, and the mounting conditions will be strict.

4.11 Adjustment of light quantity

Note that if you loosen more than one fixing bolts or anchor nuts at a time to adjust, it takes a lot of time to resetting.

4.11.1 When an optional optical axis adjusting tool (laser pointer) is used for angle adjustment

(1) Connect the digital voltmeter using the BNC receptor cable, referring to “4.6 Checking received light

quantity”.

(2) The reference light quantity is based on the output in zero calibration or voltage value of light quantity

which is described in a nameplate. If the output is not as much as that measured at the time of calibration before the adjustment, find a position where the received light quantity increases, moving the transmitter box from side to side and up and down slowly. (*1)(*2)(*3)

e.g.) In the case that the quantity of light increases when the

whole transmitter box is moved upward.

As the quantity of light increases when the light axis

→

turns downward, loosen the fixing bolt in reference to “4.7.2 How to operate the angle adjustment unit 2”.

(3) When the output not as much as that measured at the time of calibration, even if it is at its maximum on

the transmitter side, fix the box at the maximum output angle temporarily and adjust the light axis, moving the receiver box similarly. Do not loosen more than one bolt or loosen fixing bolt and nut widely in both cases of adjustment. Light axis may deflect again.

(4) Move the transmitter unit and the receiver unit from side to side and up and down to adjust until the

voltage value of light quantity of digital multimeter becomes smaller in all directions.

(5) Retighten all volts to fix them (If the light quantity decreases at retightening, adjust again).

*1) Received light quantity might not increase to its maximum that was confirmed by “4.6 Checking re-

ceived light quantity” due to the influences from dust and moisture in the stack unit, etc.

*2) When using the high-speed/AGC version (i.e. the 22th digit of code symbols is "H"), adjust the light axis

under the status that the level of AGC is "01" (refer to "5.3 Outline of screen ").

4.11.2 When an optional optical axis adjusting tool (laser pointer) is not used

(1) Connect the digital voltmeter using the BNC receptor cable, referring to “4.6 Checking received light

quantity”.

(2) The reference light quantity is based on the output in zero calibration or voltage value of light quantity

which is described in a nameplate. When the quantity of light is completely zero V, move the transmitter box from side to side and up and down slowly to find the position where the received light quantity increases. If you cannot still confirm the quantity of light, loosen the fixing bolts and nuts further, and check reaction of the digital voltmeter while moving the box back and forth slowly.

(3) If you find reaction of light quantity increases, fasten the fixing bolts and nuts temporally, and perform

the operation in 2). (*4)

(4) If output is not as much as that measured at the time of calibration even if output is at its maximum on

the transmitter side, fix the box at the maximum output angle temporality and adjust the light axis, moving the box on the receiver side similarly. When you can confirm the output at the time of adjusting any of the boxes, do not loosen the fixing bolts and nuts too much, or the light axis can deflect further. Do not loosen more than one bolt or loosen fixing bolt and nut widely in both cases of adjustment. Light axis may deflect again.

(5) Move the transmitter unit and the receiver unit from side to side and up and down to adjust until the

voltage value of light quantity of digital multimeter becomes smaller in all directions.

(6) Retighten all volts to fix them (If the light quantity decreases at retightening, adjust again).

tive to attach the ferrite core to the power cable near the inlet of the control unit (outside the box).

CAUTION

• Wire the outlet for connecting power supply with the wire diameter of 1.25mm or more.

• Connect to the outlet with grounding line (class D grounding). For connection of ground line, use the ground line with the wire diameter of 2mm or more.

• For connection of the signal connecting cable, use a shielded wire in order to suppress the influences by noise.

• Wire the output contact and the contact input connecting cable with the wire diameter of 1.25mm.

• After the AC power cable is connected, put a power terminal cover on.

• Do not install the instrument near objects which considerably disturb power waveforms. Do not share their power supplies either. Otherwise, it may cause a display error.

• Power supply and output signal lines should be separated from each other.

• As the wire is connected to each terminal, use a solderless terminal (for M4).

• As the solderless terminal is used for AC power cable and ground line, chose a type of solderless terminal that caulks cores and coverings separately.

4.13.2 Connecting analog input/output

Connect the analog input and output properly, referring to “3.2 Input/output terminal of control unit (excluding CO+O

analyzer)” or “3.3 Input/output terminal of control unit (CO+O2 analyzer)”. Provide analog out-

put of 4 to 20mA DC, 1 to 5V DC, etc, according to the ordering contents. For connection of the signal cable, use a shielded wire or an insulated converter (LDC-16H01, manufactured by Fuji Electric Technica Co., Ltd. or equivalent) to supress the influences by noise. Analog input is 4 to 20mA DC. Connect the input signal corresponding to the equipment.

Note) When you connect the analog input to the analog output terminal, the printed circuit board may be

damaged. Check the terminal before connecting them.

4.13.3 Connecting contact input/output

Connect the contact input and output properly, referring to “3.2 Input/output terminal of control unit (excluding CO+O with the separately submitted approved drawing, connect the contact input/output as shown in the drawing. For wiring, use shielded wires of which diameters are 1.25 mm or more. Unassigned terminals may be connected to the internal circuit. Do not use them as repeating terminals.
