Operation

3.1 Operation

Device operation is dialog driven from the display with the aid of the three Function buttons (see Fig.

1 "Device overview").

Environmental Factors

A number of environmental factors may affect the gas sensor readings, including changes in pressure, humidity and temperature. Pressure and humidity changes affect the amount of oxygen actually present in the atmosphere.

Pressure Changes

If pressure changes rapidly (e.g., stepping through airlock), the oxygen sensor reading may temporarily shift and possibly cause the device to go into alarm. While the percentage of oxygen may remain at or near 20.8 Vol %, the total amount of oxygen present in the atmosphere available for respiration may become a hazard if the overall pressure is reduced by a significant degree.

Humidity Changes

If humidity changes by any significant degree (e.g., going from a dry, air conditioned environment to outdoor, moisture laden air), oxygen readings can be reduced by up to 0.5 %, due to water vapor in the air displacing oxygen.

The oxygen sensor has a special filter to reduce the effects of humidity changes on oxygen readings.

This effect will not be noticed immediately, but slowly impacts oxygen readings over several hours.

Temperature Changes

The sensors have built-in temperature compensation. However, if temperature shifts dramatically, the sensor reading may shift. Zero the device at the work site temperature for the least effect.

3.8 Bump Test

WARNING!

Perform a Bump Test before each day’s use to verify proper device operation. Failure to perform this test can result in serious personal injury or death.

Bump test frequency is often stipulated by national or corporate regulations; however, bump testing before each day’s use is generally the accepted best safety practice and is therefore MSA’s recommendation.

This test quickly confirms that the gas sensors are functioning. Perform a full calibration periodically to ensure accuracy and immediately if the device fails the Bump Test. The Bump Test can be performed using the procedure below or automatically using the GALAXY GX2 Test Stand.

CSA requires (per 22.2 NO. 152) that combustible sensor sensitivity be tested before each day's use on a known concentration of methane equivalent to 25 to 50 % of full scale concentration. ACCURACY

MUST BE WITHIN 0 to +20 % OF ACTUAL. Correct accuracy by performing the calibration procedure

described in chapter 3.10 "Calibration".

 symbol). The  symbol, and the gas type of the sensor nearing its end of life, will blink for 15 seconds when the device returns to Normal Operation mode. When in Normal Operation mode, the

 symbol is continuously displayed.

Finishing Calibration

(1) Close the valve on the regulator.

(2) Remove the calibration cap.

The calibration procedure adjusts the span value for any sensor that passes the calibration test; sensors that fail calibration are left unchanged. Since residual gas may be present, the device may briefly go into an exposure alarm after the calibration sequence is completed.

•

Autocalibration Failure

If the span calibration is unsuccessful:

•

If the device cannot calibrate one or more sensor(s), it goes to the SPAN ERR page and remains in alarm until the  button is pressed.

A sensor life indicator is displayed (Alarm symbol and

 symbol) to show the sensor has reached its end of life and should be replaced.

This occurs if the span calibration is unsuccessful twice.

The device will remain in alarm state until the  button is pressed.

The Alarm symbol and

 symbol will remain on the display until a successful calibration or sensor in question is replaced.

A span calibration can fail for many reasons besides sensor at the end of his life.

Response notes

(1) Some compounds may reduce the sensitivity of the combustible gas sensor by poisoning or inhibiting the catalytic action or by polymerizing on the catalytic surface.

(2) Multiply the displayed % LEL value by the conversion factor above to get the true % LEL.

(3) These conversion factors should be used only if the combustible gas is known.

(4) All factors are based on the IEC 100 % LEL levels a) i.e. Methane 100% LEL = 4.4 Vol %, b) Pentane 100% LEL = 1.1 Vol % c) Propane 100% LEL = 1.7 Vol %

(5) These conversion factors are typical. Individual units may vary by ±25 % from these values.

(6) The results are intended for guidance only. For the most accurate measurements, a device should be calibrated using the gas under investigation.

Technical Data

(7) The conversion factors for the standard EX and the specialized EX-H and

EX-M sensor are the same except for EX-H and Nonane and o-Xylene. The conversion factors for these two vapors are therefore especially mentioned in the table.

Oxygen

The oxygen sensor has built-in temperature compensation. However, if temperature shifts dramatically, the oxygen sensor reading may shift. Zero the device at a temperature within 30 °C (86 °F) of the work place temperature for the least effect.
