Maintenance - Dräger X-dock 5300 Instructions For Use Manual

5.5 After use
1. If required, remove instruments from modules.
2. Close the test gas cylinders.
NOTICE
i i
To keep energy consumption low, Dräger recommends
switching off the station after use according to the
Instructions for Use.
If the gas detectors are stored in the station, this will
lead to increased power consumption by the gas
detectors. If the gas detectors are stored in the station,
Dräger recommends using the X-am 125+/8000+
modules.
NOTICE
i
i
Prior to storing gas detectors in the maintenance
station, select the "Flush" test option to ensure that the
module is flushed with fresh air after completion of a
test.
NOTICE
i
i
Never store the X-am 125 gas detectors for extended
periods (max. 2 months) without a power supply as the
internal buffer battery will run down.

Maintenance

6.1 Maintenance intervals
NOTICE
i i
The maintenance intervals must be established in
each individual case and shortened if necessary,
depending on safety considerations, process
conditions, and the technical requirements of the
equipment. Dräger recommend a Dräger service
contract for all maintenance activities and that all
repairs are carried out by Dräger.
6.1.1 Before every start-up
The following work must be carried out before every start-up of
the equipment:
Check the hoses for dirt, brittleness and damage and

replace if necessary.
Check the hoses are secure, to prevent escapes of gas.

Check that all cable connections are secure.

Visual inspection of the modules and sensor seals. If very

dirty or if there are visible defects, the sensor seal must be
replaced.
6.1.2 Annually
Inspection of the entire X-dock station by competent
personnel.
6.2 Replacing a test gas cylinder
If a test gas cylinder is used up or has expired (expired for
calibration only), the station automatically checks whether
another suitable test gas cylinder is connected. If so, the
suitable test gas cylinder is used automatically.
To replace an empty test gas cylinder with an identical full test
gas cylinder:
1. Close empty test gas cylinder valve.
2. Unscrew the pressure regulator valve from the test gas
cylinder.
3. Screw pressure regulator valve on full test gas cylinder with
identical test gas concentration.
4. Slowly open the test gas cylinder valve.
To replace a test gas cylinder with a test gas cylinder with other
test gas concentration:
1. Close empty test gas cylinder valve.
2. Unscrew the pressure regulator valve from the test gas
cylinder.
3. Screw pressure regulator valve on full test gas cylinder with
changed test gas concentration.
4. Slowly open the test gas cylinder valve.
5. Reconfigure the corresponding test gas inlet, see
chapter 4.6 on page 24.
