Maintenance and Cleaning
The ARL EQUINOX X-Ray diffractometer is designed to require only minimal maintenance
operations. However, several preventive maintenance tasks should be performed regularly to
keep an optimal working state of your instrument. Please refer to Appendix 4: Periodic
Preventive Maintenance on page
to find the reminder of the periodic preventive
maintenance operations. Furthermore, the cooling fluid and the detector gas cylinder must be
replaced periodically.
8.1 Replacing the Gas Cylinder
Note
This task should be performed by qualified personnel only
We advise to replace the gas cylinder as soon
as it reaches 20 Bar. The cylinder pressure can
be checked using either the side window or by
opening the side cover and reading the indicator
(the left indicator in case of using the FM53 gas
regulator.
Gas circuit
The gas cylinder (1) is connected to the
instrument gas inlet (2) fast connector. The T (4)
distributes the gas in on the detector (3) and the
external gas inlet (5). The detector out (6) is
connected to the T (7) distributing the fast
connector of purging (8) and the micro-leak
valve (9). This one is connected to the isolating
valve (10) and go to external exhaust (11). The
last circuit is the overpressure line from the
safety valve (12) to external exhaust (13).
CAUTION!
The gas leak valve (9) is adjusted in the factory and should not be modified. It allows
to control the right consumption of gas, allowing an optimum regeneration of the gas
inside detector.
1.
Power down the instrument and unplug the power supply cord from the power supply. See
Section Operation on page
2.
Close the isolating gas valve (10).
