z The charging time is typically 4 hours. z A new NiMH power pack reaches its full capacity after three

complete charging/discharging cycles.

z Never store the instrument for extended periods without

being connected to a power source (maximum of 2 months) because the internal buffer battery will drain.

Charging with the multiple charging station

z A maximum of 20 instruments can be charged at the same

time on the power pack (order no. 83 18 805) of the multiple charging station.

z When attaching the charging modules, disconnect the

power pack from the mains supply!

z Position the instrument on an even and level surface.

1. Turn the slots of the interlock into a horizontal position by using a screwdriver or coin.

2. Insert the fastening lug (2) of the charger module (simultaneous power feed) until it engages.

3. Close the lock (1) with a quarter turn (slot is positione d vertically).

4. Attach additional charging modules in the same way.

5. Connect the power pack to the mains.

6. Insert the switched off instrument into the charger module.

{ Display LED (5) on the charging cradle:

z If a fault occurs:

{ Remove the instrument from the charging module and

insert it again.

z If the fault still occurs, have the charging module repaired.

{ It takes approx. 4 hours to fully charge an empty

rechargeable battery.

z In the event of a short circuit or if the power pack is

overloaded:

{ The red "Overload" LED (3) is on, and an audible

alarm sounds.

{ After the fault has been corrected, the alarm is switched

off automatically and the charging process is restarted.

{ In the event of a power failure, the instruments already

charged will be protected from discharging.

WARNING

Explosion hazard! Do not charge underground or in explosion hazard areas!

The chargers are not designed in accordance with the regulations for fire damp and explosion protection.

NOTICE

Even if the instrument is not used, Dräger recommends storing the instrument in the charging cradle (chargingmodule X-am 1/2/5000, order no. 83 18 639).

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 11130 = mixed gas with 50 ppm CO, 15 ppm H

2.5 vol. % CH

, 18 vol. % O

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 concentration

O2: ±0.6 vol. %

TOX: ±20 % of the test gas concentration

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:

z Acknowledge the alarm.

If the displays are outside of the above-mentioned ranges:

z Calibrating/adjusting the instrument, see section 5 on

page 17.

3.4.2 Menu implementation with the documentation of results in the instrument memory

The setting to "Quick bump test" or "Accelerated bump test" is made using the PC software Dräger CC Vision. In the "Quick bump test" a check is carried out as to whether or not the gas concentration has exceeded alarm threshold 1 (with oxygen, the test checks that alarm threshold 1 has not been reached). In the "Accelerated bump test" a check is carried out as to whether or not the gas concentration has exceeded alarm threshold 1 (with oxygen, the test checks that the alarm threshold has not been reached) and whether or not the gas concentration has reached the set bump test concentration.

Setting on delivery: Quick bump test.

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 H

S, 2.5 vol. % CH4, 18 vol. % O

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 Quick menu and

select the bump test, page 16. The current gas concentration values and the special symbol » « (for bump test) flash.

6. Press the key to start

the bump test.

7. Open the test gas cylinder

valve to let test gas flow over the sensor.

 If gas concentration exceeds

the alarm thresholds A 1 or A 2 the corresponding alarm will occur.

Ending the bump test:

After the set bump test concentration has been reached or a gas alarm has been triggered (with "Quick bump test"):

z The display containing the

current gas concentration changes with the display »OK«.

z 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.

z If the concentration values have now fallen under the A1

alarm thresholds, the instrument returns to the measuring mode.

z 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.

z Activating the instrument for the automatic bump test. z Composition of test gas (mixed gas) – standard on delivery:

50 ppm CO, 15 ppm H

S, 2.5 vol. % CH4, 18 vol. % O

z 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 T e st Stat ion 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.

z If the concentration values have now fallen under the A1

alarm thresholds, the instrument returns to the measuring mode.

z 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

z During operation, the measured values for every measured

gas are displayed.

z If a measuring range is exceeded or not reached,

the following displays are shown instead of the measured value display:

z For O

concentrations under 8 vol. % an error is indi cated with »« at the ex-channel instead of the measuring value as long as the measuring value falls below the prewarning threshold (only if measuring range is b100 %LEL, not for >100 %LEL (heat conductance)).

z 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.

6 Operation with pump

With Dräger Pump X-am 1/2/5000

Accessories: Dräger Pump X-am 1/2/5000, sampling hose and probes, see section 12 on page 31.

Commissioning and performing the measurement:

z Refer to the Instructions for Use of the Dräger

Pump X-am 1/2/5000.

With manual pump adapter and rubber ball pump

Accessories: For manual pump adapter, rubber ball pump, sampling hose and probes, see section 12 on page 31.

Commissioning and performing the measurement:

z Refer to the Instructions for Use of the accessories used.

Observe the following during measuring mode with pump

z 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.

z 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.

z 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 flushin g 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
