１．Introduction

In order to use the Gas Det ect or safely, be sure to observe the followin gitems.

●This product is an O /H S detector to prevent from occurring oxygendeﬁciency or gas poisoning by alarm buzzer, lamp and vibration when the gas
concentration exceeds the alarm set value.

DANGER● Description of Symbols

In order to use the Gas Detector safely, be sure to observe the following
symbols.

DANGERWARNING

Failure to observe the precautions indicated by thissymbol will create a imminently dangerous or hazardous
condition resulting in serious injury or death.
Failure to observe the precautions indicated by thissymbol will create a potentially dangerous situationthat may result in serious injury or death.

CAUTION

Failure to observe the precautions indicated by thissymbol will create a potentially dangerous situation
resulting in minor injury or property damage.

NoteThis symbol indicates advice on how to handle theinstrument.

XOS -2200 is explosion-proof（Japan）.
Use the detector as directed below.
•ry•••••••

battery―1 ―In the event of an alarm, immediately take all necessary
treatment to prevent gas poisoning.
Do not block the gas detection intake in use.
In case liquid spill is happened from the sensor element(by mechanical shock etc.), immediately wash clothes inwater when liquid is adhered.
In case of getting liquid in eyes or ears, immediately
submit to medical treatment after receiving ﬁrst aid bywater.
Be sure to execute daily check and periodic check.
Do not disassemble or modify XOS -2200 because it could
cause to lose explosion-proof design.
Use the product in compliance with applicable laws andregulations.
Do not drop or hit the product to avoid intense mechanicalshocks and vibrations. It may aﬀect the functions.
Avoid storing the product or leaving it for a long period oftime in places or car subject to high temperatures andhigh humidity or low temperatures and low humidity.
Do not use the product at outside the operating
temperature/humidity range, and under rapid temperature/humidity change. It may aﬀect the functions.
When the pressure of the measurement environment is
diﬀerentfrom the standard atmospheric pressure (at highaltitudes, etc.), perform a pressure correction of themeasured values to avoid a pressure dependence ofoxygen sensor.
Keep the product away from exposure to water orcondensation.
In case of condensation, dry completely before using theproduct.
Wear the detector where audible, visible and vibration
alarm can be noticed easily.
Only use speciﬁed battery (Panasonic alkaline AAA
battery LR03X or Toshiba alkaline AAA battery LR03).
The use of unspeciﬁed battery may impair the detectorʼs
explosion-proof performance and product performance.

３．Operational Procedure① Turning the power onONOFFPEAK

Press and hold the [Power (PEAK)] switch forapprox.3 seconds. “on” will be displayed,
a countdown will begin with “3,” “2,” and “1”,the gas alarm settings will be displayed, and then air adjustment
will be automatically performed. Upon the completion of air adjust-ment, the measured gas concentrations will be displayed.

WARNING Make sure to turn on the power in clean air. Since air adjustment

will be conducted automatically, the incorrect gas concentrations
will be displayed when turned on in gas atmosphere.

3 seconds to perform air adjustment manually.

ADJ.

Gas detection is ready after air adjustment is complete.

NoteWARNING

When the target gas is O , check that the blinking "23.0%" isdisplayed during air adjustment. When the sensor approaches
the end of its lifetime, a value less than 23.0% is displayed.
Replace the oxygen sensor with a new one before the value
reaches "21.0%".

Accura te ga s c onc entra tion res ults c a nnot
be obtained if the gas concentration over themeasuring range is detected for a long time.

CAUTION

For simultaneous alarms,priority is given to second stage alarm
rather than ﬁrst stage alarm.
When the gas concentration display exceeds the service
OLa rera nge, the s ervic e range upper li mit a nddis played alternately.

Note● First and S econd stage alarm
If the gas concentration exceeds the ﬁrst or second stage alarm concentration
setting level,alarm activation is accompanied by sound and vibration and thegas concentration display,alarm display,and alarm lamp blink.

４．Replacing Battery
The remaining battery level indication decreases in increments as thebattery level decreases as shown below:
Before remaining battery level is exhausted,the last indication will blink withan intermittent alarm sound in -second intervals.(Backup alarm)
When the remaining battery level is exhausted. [Err.b] is displayed andaccompanied by a continuous alarm sound.The product will no longer
operate.
Stop the alarm sound by turning the power OFF.

６．MaintenanceThis product is a precision instrument. Please perform the periodical checks andinspections below to maintain the detectorʼs performance and ensure safety.
In the event of a failure to follow the safety precautions (page 2), such as impact shockfrom dropping or exposure to water, or use in conditions outside the speciﬁcations(page 13), such as usage in temperature/humidity exceeding the speciﬁed range,
please contact New Cosmos or your New Cosmos representative for inspection.
A comprehensive description of the current situation would be appreciated when you
contact us.

Model

Note

This product uses a very small amount of current even after
turned oﬀ, to stabilizethe sensor. Keep the battery in the producteven when the product is not being used.
If the battery is removed from the product for a long period of time,
initial stabilization of the sensor may take longer, causing an error. In
such a case,insert the battery and leave the product with the power
being oﬀ for one day or longer before use.

― 10 ―

Alarm activation and use at low temperature may
shorten the battery life.

④ Gas sensor openings

Check that the gas sensor openings A and B are not blocked and the ﬁlter
elements are clean and dry. Replace the elements if dirty or wet.
(See “Replacement Parts” on page 5).

（2） Periodic Check

Check the product accuracy at least once a month and perform gas calibration
at least once every 6 months. It is recommended to contact New Cosmos or
your New Cosmos representative to perform a periodic inspection including
sensor replacement at least once a year (fees apply).

C A U T IO N

Execute daily check in clean air before use.
① Operation
Check alarm sound, alarm lamp,vibration and LCD work properly when thedetector is turned on. If not ,request repairs.
② Alarm function
Check the alarm indications such as alarm sound , alarm lamp andvibration by having the detector draw gas at a level that slightly
exceeds the alarm level.
In the event of an abnormality in the way the gas concentration
readings change , such as the alarm lamp does not ﬂicker or the buzzer
does not sound, request repairs.
③ Remaining battery level
Check the remaining battery level of the gas detector.
If the remaining battery level is low,replace the battery.

Be sure to execute the air adjustment in clean air.
Accurate gas detection results cannot be obtained if theadjustment is made in an atmosphere mixed with gases.
Execute the air adjustment at least once a day. Inaddition,make the air adjustment when the work
