13 3.4 Running the bump test 3.4.1 Manual implementation without documentation of the results in the instrument memory 1. Prepare a test gas cylinder, the volume flow must be 0.5 l/min and the gas concentration must be higher than the alarm threshold concentration that is to be tested. Example test gas cylinder 68 11 130 = mixed gas with 50 ppm CO, 15 ppm H2S, 2.5 vol. % CH4, 18 vol. % O2 2. Connect the test gas cylinder with the calibration cradle (order no. 83 18 752). 3. Vent the test gas into a fume cupboard or into the open air (with a hose connected to the second connector of the calibration cradle). 4. Switch on the instrument and insert it into the calibration cradle – press downwards until it engages. 5. Open the test gas cylinder valve to let test gas flow over the sensors. Recommendation: Wait until the instrument displays the test gas concentration with sufficient tolerance – Ex: ±20 % of the test gas concentration1 O2: ±0.6 vol. %1 TOX: ±20 % of the test gas concentration 1 Wait until at least alarm threshold A1 or A2 has been exceeded, however. If the alarm thresholds are exceeded, the instrument displays the gas concentration in alternation with » A1 « or » A2 « depending on the test gas concentration. 6. Close the test gas cylinder valve and remove the instrument from the calibration cradle. If the concentration has now fallen under the A1 alarm threshold: � Acknowledge the alarm.

Use Ending the bump test: After the set bump test concentration has been reached or a gas alarm has been triggered (with "Quick bump test"): � The display containing the current gas concentration changes with the display » OK «. � The bump test that was carried out is documented with the result and date in the instrument memory. 8. Close the test gas cylinder valve and remove the instrument from the calibration cradle. � If the concentration values have now fallen under the A1 alarm thresholds, the instrument returns to the measuring mode. � If the set bump test concentration is not reached within the set time, an error is issued. � The fault message » « appears and » « is displayed instead of the measured value on the faulty measuring channel. � In this case, repeat the bump test or calibrate the instrument, page 21. The bump test can also be run automatically. The "Bump Test Station" is required for this function, see section 3.4.3 on page 14. 3.4.3 Automatic implementation with the Bump Test Station Prerequisite: The instrument first needs to be configured for the automatic bump test using the Dräger CC-Vision PC sofware. � Activating the instrument for the automatic bump test. � Composition of test gas (mixed gas) – standard on delivery: 50 ppm CO, 15 ppm H2S, 2.5 vol. % CH4, 18 vol. % O2 � Define which measuring channels should participate in the automatic bump test. All measuring channels participate in the bump test by default. 1. Prepare the Bump Test Station according to the instructions. 2. Switch on the instrument and insert it into the receptacle of the Bump Test Station until it engages. The bump test will be started automatically. The special symbol » « (for bump test) flashes. If a gas alarm (quick bump test) is initiated and the set bump test concentration (Accelerated bump test) is reached within the set time, the current gas concentration will be displayed alternately with » OK «. 3. Remove the instrument from the Bump Test Station. � If the concentration values have now fallen under the A1 alarm thresholds, the instrument returns to the measuring mode. � If there is no alarm during the bump test and the current measurements do not reach the set target concentration ("Accelerated bump test" only), an error is issued. � The fault message » « appears and » « is displayed instead of the measured value on the faulty measuring channel. � In this case, repeat the bump test or calibrate the instrument, page 21. The bump test can also be run manually, see section 3.4.1 on page 13. The Dräger CC Vision PC software can be used to enable the "Automatic calibration after incorrect bump test" option. 3.5 During use � During operation, the measured values for every measured gas are displayed. � If a measuring range is exceeded or not reached, the following displays are shown instead of the measured value display: � Excess concentrations of flammable materials can lead to a lack of oxygen. 01033366_en.eps CH4 %LEL O2 Vol% CO ppm H2S ppm 01133366_en.eps CH4 %LEL O2 Vol% CO ppm H2S ppm 01333366.eps 0 Ex %UEG O2 Vol% CO ppm H2S ppm » « (measuring range exceeded) or » «(measuring range not reached). 01133366_en.eps CH4 %LEL O2 Vol% CO ppm H2S ppm 01133366_en.eps CH4 %LEL O2 Vol% CO ppm H2S ppm

15 � For O2 concentrations under 8 vol. % an error is indicated with » « at the ex-channel instead of the measuring value as long as the measuring value falls below the pre- warning threshold (only if measuring range is �100 %LEL, not for >100 %LEL (heat conductance)). � In the event of an alarm, the corresponding displays, including the visual, audible and vibration alarms, are activated, see section 6 on page 21. If the measuring range is exceeded significantly at the CatEx channel (very high concentration of flammable materials), a blocking alarm is triggered. This CatEx blocking alarm is either acknowledged automatically through a functional oxygen channel (e. g. a channel free of warnings and defects) or manually by switching the instrument on and off in fresh air. No blocking alarm is triggered in the "methane" configuration setting when a measuring range is exceeded, because the unambiguousness of the display for methane is ensured via a separate measurement of the heat conductivity. After the measuring range of the TOX measuring channels has been exceeded temporarily (up to one hour), checking the measuring channels is not necessary. 3.6 Identifying alarms An alarm is displayed visually, audibly and through vibration in a specific pattern. 3.6.1 Concentration pre-alarm A1 The pre-alarm A1 is not latching and stops when the concentration has dropped below the alarm threshold A1. � In case of A1, a single tone is audible and the alarm LED flashes. Acknowledging the pre-alarm: � Press the key. Only the audible alarm and the vibration alarm are switched off. 3.6.2 Concentration main alarm A2 � In case of A2, a double tone is audible and the alarm LED flashes twice. After leaving the area, when the concentration has dropped below the alarm threshold: � Press the key. The alarm messages are switched off. 3.6.3 STEL / TWA exposure alarm � The STEL and TWA alarm cannot be acknowledged or cancelled. � Switch off the instrument. The values for the exposure evaluation are deleted after the instrument is switched on again. 3.6.4 Battery pre-alarm Acknowledging the pre-alarm: � Press the key. Only the audible alarm and the vibration alarm are switched off. � The battery still lasts min. 20 minutes after the first battery pre-alarm. 3.6.5 Battery main alarm The battery main alarm cannot be acknowledged or cancelled: � The device automatically switches off after 10 seconds. � Before the instrument is switched off, the visual, audible and vibration alarms are activated for a short time. 3.6.6 Instrument alarm � The instrument is not ready for operation. � For corrective measures, see“Replacing the sensors” on page 21 to page 24. � Contact maintenance or Draeger Service to rectify the problem. WARNING After exposure to concentrations above 100 %LEL, incorrect displays may occur at the CatEx channel. Check the zero point and sensitivity and adjust it if necessary before continuing to use the instrument in a concentration range of 0 to 100 %LEL. In the event of an impact load when using a CatEx sensor in the Dräger X-am 2500 that causes the fresh air display to deviate from zero, the zero point and sensitivity must adjusted.

Commissioning and performing the measurement: � Refer to the Instructions for Use of the accessories used. Observe the following during measuring mode with pump � Wait for the flushing time to elapse: Before every measurement, flush the Dräger sampling hose or the Dräger probes with the air sample to be measured. � A flushing phase is necessary to eliminate or minimise all effects associated with the use of a sampling hose or a probe, e.g. memory effects, dead volume. � The duration of the flushing phase depends on factors such as type and concentration of the gas or vapour to be measured, material, length, diameter, and age of the sampling hose or probe. Generally, when using a sampling hose (new, dry, clean), a typical flushing time of approx. 3 seconds is required for each metre. This flushing time applies in addition to the sensor response time (see the Instructions for Use for the gas detection instrument used). Example: In the case of a sampling hose with a length of 10 m, the flushing time is approx. 30 seconds and the sensor response time is in addition approx. 60 seconds. Therefore, the total time before reading the gas measuring instrument is approx. 90 seconds. The flow-rate alarm is delayed by 10 to 30 seconds depending on the length of the hose. 7 Replacing the sensors � To replace the sensors of the instrument, connect the instrument with a PC. � Replace the sensors using the PC program Dräger CC Vision.
