Description

The device monitors gases in ambient air and in the workplace. The following toxic gases can be monitored in the ambient air:

Sulfur dioxide (SO

)

Nitrogen dioxide (NO

)

Carbon monoxide (CO)

Hydrogen sulfide (H

Chlorine (Cl

)

Ammonia (NH

)

The Two Gas (Two-Tox) sensor provides two sensing capabilities in a single sensor. The following combinations are possible:

Carbon monoxide/hydrogen sulfide (CO/H

Carbon monoxide/nitrogen dioxide (CO/NO

)

Hydrogen sulfide/sulfur dioxide (H

S/SO

)

The alarm levels for the individual gases are factory-set and and cannot be changed during operation. Changes can only be made through MSA Link software.

Short Term Exposure Limits (STEL)

The STEL alarm is calculated over a 15 minute exposure.

STEL calculation examples:

Assume the device has been running for at least 15 minutes:

15 minute exposure of 35 ppm:

(15 minutes x 35 ppm)

15 minutes

= 35 ppm

10 minute exposure of 35 ppm and 5 minutes exposure of 5 ppm:

(10 minutes x 35 ppm) + (5 minutes x 5 ppm)

15 minutes

= 25 ppm

If the device is on for longer than 15 minutes, the STEL is calculated for the most recent fifteen minutes of runtime.

ALTAIR 2X 12

Description

Time Weighted Average (TWA)

The TWA alarm is calculated over an eight-hour exposure.

TWA calculation examples:

1 hour exposure of 50 ppm:

(1 hour x 50 ppm) + (7 hours x 0 ppm)

8 hours

= 6.25 ppm

4 hour exposure of 50 ppm and 4 hour exposure of 100 ppm:

(4 hours x 50 ppm) + (4 hours x 100 ppm)

8 hours

12 hour exposure of 100 ppm:

= 75 ppm

(12 hours x 100 ppm)

8 hours

= 150 ppm

If the device is ON for less than 8 hours (480 minutes), the balance of the minute ppm values is set to zero.

3.13 Calibration

The device must be calibrated if it does not pass a bump test.

Perform a bump test (see section 3.5) before each day's use to verify proper device operation. The device must pass the bump test. If it fails the test, perform a calibration before using the device.

A calibration consists of the adjustment of the sensor output to match the precise concentration value of a known, traceable, calibration gas cylinder. A calibration can be performed at any time to ensure maximum accuracy. Calibration frequency is often stipulated by national or corporate regulations; however, a calibration should be performed periodically at regular intervals or if the unit fails a bump test. MSA recommends a calibration interval of 2 months for devices with XCell Pulse technology and a maximum 6 months for devices with standard XCell sensors.

Make sure that the calibration is carried out in clean, non-contaminated ambient air.

WARNING

Regulators and tubing used for bump testing and calibrating Cl

or NH

must be labelled by the user for that specific gas and must only be used for that gas exclusively in the future.

Due to high reactivity of Cl

and NH

gas, ambient humidity and calibration tubing material can react with the gas and cause the concentration reading to be lower than the actual concentration. When calibrating or bump checking with these gases, use dry tubing (for adequate material see section 7). For best calibration, use the shortest possible tubing to connect to the calibration cylinder for this gas.

ALTAIR 2X 37

Use

Devices must be calibrated:

after subjected to physical shock,

after any extreme changes in the atmospheric temperature,

after use under high gas concentrations,

if the bump test/FAS failed,

at certain intervals by local procedures.

Calibration mode can be entered after the info screens have been displayed

(see Fig. 10).

(1) Press button for one second to access the information page.

(2) When ZERO? is displayed, press the button for a zero calibration.

If no zero calibration is carried out, the device returns to normal operating mode.

During the setup, the hour glass, the no calibration gas icon and the measured gas concentration are displayed.

If the zero cal operation fails, ERR is displayed. The device returns to normal operation after a button press.

If the zero calibration is successful, PASS is displayed followed by SPAN?.

(3) During the SPAN? display, press the button to start the calibration mode.

(4) Feed test gas into the device:



Connect the regulator (screwed on the calibration gas cylinder) and the sensor opening with a tube and open the regulator.

Possible test gases

 Section 7.

WARNING

The concentration of the test gas used must match the stipulated in

Section 5.2 to calibrate the sensor correctly.

For two gas detectors, only calibration gas mixes can be used to calibrate the sensor correctly.

An incorrect calibration can lead to serious personal injury or death.

The current gas reading, hour glass and calibration gas cylinder icon are displayed.

If calibration is successful PASS is displayed and the device returns to normal operating mode.

ALTAIR 2X 38

Use

(5) Close the regulator.

For devices with XCell Pulse technology, WAIT is displayed together with the “no gas cylinder” icon. This shows that the regulator must be closed and the calibration gas must be removed from the device. Once gas is removed, the device will perform a secondary calibration operation (pulse check) on the sensor. During the pulse check, a countdown is displayed. The device will then return to normal operating mode.

If the span calibration fails, ERR is displayed. The device returns to normal operation after a button press.

(6) If calibration fails, check:

 whether the sensor inlet or sensor surface is dirty,



 whether the correct test gas was used, whether the test gas cylinder is empty or the date has expired, whether the test gas hose was connected to the sensor, whether the flow regulator is set to 0.25 l/min.

(7) If necessary, repeat steps (1) to (6).



PASS

is displayed. Otherwise (ERR), the device must be taken out of use.

If the calibration is successful, a

 is displayed for 24 hours. If the safe LED

(green) option is enabled, the green LEDs will flash periodically.
