The T-3280 is a gas monitioring instrument especially designed for continuous surveillance of hazardous gas concentrations. The instrument is designed to interface with standard 4-20mA alarm or control systems. The T-3280 is the simple solution to all your “Point of Use” gas detection needs. Based upon the markets smallest and most reliable electrochemical cell technology, the T-3280 offers the flexibility, simplicity and application ease. The T-3280 can be purchased in either an analog or digital configuration allowing it to interface with new or existing facility control technologies. Warranty

Thank you for purchasing this product. To get maximum use of the features of your new product we recommend that you follow a few simple steps:

Read the guidelines for safe and efficient use.

Read all the terms and conditions of your Warranty.

Save your original receipt. You will need it for warranty repair claims. Should your product need warranty service, you should return it to the dealer from whom it was purchased or contact

1、If, during the warranty period, this product fails to operate under normal use and service, due to improper

materials or workmanship, subsidiaries, authorized distributors or authorized service partners will, at their option, either repair or replace the product in accordance with the terms and conditions stipulated herein.

Conditions The warranty is valid only if the original receipt issued to the original purchaser by the dealer, specifying the date of purchase, is presented with the product to be repaired or replaced. Reserves the right to refuse warranty service if this information has been removed or changed after the original purchase of the product from the dealer.

２、 This warranty does not cover any failure of the product due to normal wear and tear, damage, misuse, including but not limited to use in any other than the normal and customary manner, in accordance with Barber user guide for use, faulty installation, calibration and maintenance of the product, accident, modification or adjustment, even tsbeyond human control, improper ventilation and damage resulting from liquid or corrosion.

3、This warranty does not cover product failures due to repairs, modifications or improper service

Performed by a non-A Barber authorized service workshop or opening of the product by authorized persons. ４、the warranty does not cover product failures which have been caused by use original accessories.

5、This warranty becomes void if approved AC/DC adaptor or battery is used.

6、Tampering with any part of the product will void the warranty.

7、Damage to sensors can occur through exposure to certain sensor poisons such as silicones, tetraethyl lead,

paints and adhesives. Use sensors in these environments containing these materials may (at the discretion) void the warranty on the sensor head. Exposure to gas concentrations outside of the design range of a specific sensor head can adversely affect the calibration of that sensor and will also void this warranty as it applies to the replacement of sensor heads.

8、Barber makes no other express warranties, whether written or oral, other than contained within this printed

limited warranty. To the fullest extent allowable by law all warranties implied by law, including without limitation the implied warranties of merchantability and fitness for a particular purpose, are expressly excluded, and in no event shall be liable for incidental or consequential damages of any nature what so ever, however they arise, from the purchase or use of the product, and including but not limited to lost profits or business loss.

9、Some countries restrict or do not allow the exclusion or limitation of incidental or consequential damage, or

limitation of the duration of implied warranties, so the preceding limitations or exclusions may not apply to you. This warranty gives you specific legal rights, and you may also have other rights.

WARNING

Do not switch the monitor on before reading the User Guide.

Do not expose the monitor to gas concentrations above there commended maximum range

Do not place the sensor head in a gas stream-the monitor is designed to measure ambient levels of ozone and uses ‘active sampling’ to achieve this. Read these simple guidelines. Ignoring these guidelines may be hazardous.

USE SENSIBLY

Use only as per this user guide.

Brief Introduction

● Summary

T-3280 Intelligent combustion gas probe monitors the concentration of combustible hydrocarbon gas with catalytic combustion technique. The probe outputs a anolog signal (4-20mA) or a digital signal (MODBUS),which is proportional to the concentration or detected gas.

The probe has two-stage alarm replay output for high/low alarm application . One independent relay is used as failure output . All change of alarm value and alarm delay output and selection of alarm increase of alarm A1 and A2, and changes of displayed scaling position , range and address code are to be performed with hand-held programmer or receiver via “comm” menu.

● Probe connecting to power supply

Four-bit LED display(A-1) for one second, and then display (XX) which is A1 alarm value . The five very highlight red LED lamps of alarm A1 blink for three seconds . Then display(A2)for one second . The displayed(YY) is A2 alarm value . The five very highlight red LED lamps of alarm A2 bilk for three seconds . Then it displays (t-30)with 30seconds counting down. The enters into polarization and directly

goes into test mode . At this moment, it displays the current value of gas concentration.

● Service life of sensor

The sensitivity and service life of the sensors will be decreased within eighteen months under high-temperature and high-humidity conditions . In case of only tested gas presenting against leakage at field and no other gases presenting continuously, the sensor may be kept with best sensitivity within eighteen months and can be applied after eighteen months to twenty-four months. However, it is recommended to replace the sensor .The replacement cycle depends on the field conditions.

The standard sensor guarantee period is only used for detection application with leakage existing . If the sensor id used as gas analyzer for production line, such guarantee period is invalid. Because the gases in production process are changeable, the humidity, temperature ,gas flow and pressure will influence the service life of the sensors according to experiences.

The PPM-level sensors will be damaged if they are exposed in the tested gas of %concentration for doses of doses of hours .Then the sensor shall be replaced promptly.
